- Glow in the dark soldiers, circa Civil War era. Discovered by a high school student. I love this story. It really shows the importance of asking questions.
- So 3-D printers might be making houses soon. I can see this being very useful for martian or lunar colonies since it could potentially be automated.
- And of course, one more Olympics link.

I enjoyed reading this article about diving. It answered a lot of my questions and added some physical elements. Brown commented on how she had to tape her wrists in order to enter the water correctly and with less damage to her body because she wasnt strong enough. Last year in physics, we learned that falling objects gained speed, a very unique strong body is needed for a successful, safe dive. Divers seem to have a certain body shape than for example a free style swimmer. I can only imagine how much force is needed to dive off of the board. This refers to all olympic sports; although the athletes have different bodys certain muscles that are used more often in their sport are accentuated.
The "rip" effect is seems very difficult for the divers this olympics, I only witnessed one or two from an athlete from china.
I found the article, "Giant 3-D Printer to Make An Entire House in 20 Hours," very interesting. However, I also find that this new robot and device will bring much more unemployment and make the already bad economy worse. If it takes a day to build a house that is supposed to take 6 months to build, there will be a huge increase in the number of houses. Then there will be too many houses and not many will be sold. Thus, resulting in a worse economy. We should stick to hard work and not make robots that can take the jobs away from hard working people.
On the other hand, this robot may be used to create jobs rather than take to take them away. Instead of building houses, it could build big factories that would increase production in the US and give people jobs at the factories. If the factory gives more jobs than the amount of workers needed to build a factory, the economy will improve, giving more jobs on a daily basis.
This 3-D printer may be beneficial to the world if used correctly.
After reading "Giant 3-D Printer to Make An Entire House in 20 Hours" I was astonished to discover that we have developed technology advanced enough to potentially create an entire house down to the wiring completely by machine without actual construction workers this quickly. I would have expected something like this to occur much further in the future. This, as stated, could start other-world colonies and we wouldn't have to risk human lives. After all, it would be a first attempt at building any kind of life-sustaining structure on another planet and would be extremely dangerous for humans to work physically on the planet that has no breathable oxygen in it's atmosphere. With this advancement there are draw-backs. Some of which would be unemployment, with a machine doing all the work there would be less demand for human workers and mostly demand for a few technicians to monitor the machines. Also it could cause us to go through natural resources even faster with building being so feasible now that a machine could do it in 20 hours. This would mean the potential for more deforestation and certain minerals to be depleted quicker. I personally would love to see an off-world colony before I die of old age but do we really need another machine to take more jobs from people here on Earth? Not everyone has a degree in robotics and programming and would not be able to get a job maintaining one of these advanced computer systems.
Although the 3-D printers of now are probably not able to create entire buildings, I can see their potential as a cheaper alternatives to human labor or in possible planet colonization in the near future where conditions are hostile to human life. However, the one thing that worries me is that it will replace the builders of today, possibly causing unemployment rates to maybe go up. Despite this, it could be a worthwhile option in the future when the technology gets better, creating cheaper housinig and causing less injury when these buildings are being created.
I found the article about diving to be very interesting due to the fact that a lot of science goes into doing something that is second nature to some people. They have to be able to put in the right amount of power and torque their body the perfect way in order to enter the water as smoothly as they do. If any of these elements is off, the end result would not be there and the "rip" described in the artle would not be there. I think that it is amazing that even when someone is going at about 35 miles an hour while still accelerating, they are not hurt when they hit something at would feel like cement because of the fact that they entered the water a certain way. Those swimmers that cannot do a rip dive could therefore feel a lot of pain because they had therefore not entered the water the correct way.
I found the article "Giant 3-D Printer to Make An Entire House in 20 Hours" to be extremely fasinating. 3D-printing has revolutionized the way we can make everyday objects from lego pieces, to guitars, and from car bodies to artificial livers. Seems really cartoonish, right? But the scale of this evoloution could be much bigger if the “printers” themselves scale up enough to incorporate structures as large as houses. We live in a world where we survive and live off of technology. Technology has transformed to a level thats mind bobbling. The idea of making houses and buildings with 3d printers seems to be very robotic. Even though this is such a great concept,this idea could put unemployment at risk. With less hours and less work needed, the less jobs there will be. We already have seen machines take over majority of labor, this will take it over the top. If this advancement is put into place, there will be alot of tension and disruptions among our society. This thought provking system will need highly educated people to make it work. Sooner or later highly educated labor will someday replace a number of low-tech skilled jobs. Are our younger generations capable of that? Yes learning and advancing is a part of life. Technology can be for the good, however it could potentially put at risk our communites, our nation and even the world.
I found the article “Giant 3-D Printer to Make an Entire House in 20 Hours” to be very fascinating. It is indeed a marvel that technology in a short span of about 200 years, has come so far as to build houses in less than a day’s time. While it is remarkable that the construction of actual houses could be done by the application of the 3D printer technology, the other possibilities that consequently arise from this development are endless as well. For if houses can be constructed using the said method, the same 3D printer technology can construct bridges, super fast rail networks, urban infrastructure, stadiums, ports and airports as well in no time. The rate of growth in infrastructure and thereby the overall quality of life will be phenomenal. By the same extension of the technology, several other expensive equipment, like automobiles, planes, etc. can be made at perhaps fractional costs on account of much faster manufacturing cycles. Life Sciences can be another area that can make huge gains from adopting the technology. Present day surgeons, for example, use 3D Computer Imagery (MRI/CT Scan) to determine the precise location of their surgical efforts. It can simplify their job enormously and make it hugely safer for the patients if the surgeons are able to conduct dummy surgeries on real life 3D replicas.
It is really incredible, how technology advances so fast, technology can be used for several things, like us blogging comments on this website, to helping save people in hospitals. Having the printer build in unmanned locations like in the sea, or on Mars and the Moon will be a great idea. An invention like this will clearly put the USA ahead of the world.
Initially, I was shocked to hear about 3-D printers planning to build houses. Technological advancements never cease to amaze me and as the world ages, there will be even bigger and better advancements. There are pros and cons to a 3-D printer potentially building a well-structured, sustainable house. A con would be that unemployment rates will increase, however, the cost of the house would be less. I agree with the article where it says that the models could be ideal for emergency housing, such as hurricane victims. The idea of 3-D printers creating houses is a risky idea because one cannot be sure that the house can withstand natural obstacles such as high winds, rain, and snow.
3D printer making houses? Great! Not if you're a labor worker. As Sagar has said, this can either make or break jobs, and as I said humans are a lazy species, this 3D printer will more likely than not break jobs. Not only that, but I would hate the fact that machines will soon take over our lives. I mean, they already did, just look at this blog, Facebook, phones, etc. Did machinery already take over? We've already seen Wattson beat Ken Jennings and Brad Rutter in Jeopardy, do we really need another machine to take over our labor lives?
You know the world is advancing way to quickly when professors are talking about 3D printers making houses. Honestly, I wouldn't want to live in a house entirely made by a 3D printer. You never know the little nuances that can happen. What is the printer runs out of some material or forgets to form a certain piece that can potentially lead to bigger disasters. I barely trust the internet as it is now, how can I possibly trust a printer to create a house. This machinery will also be very costly. No only will it be costly, but also it will be deleterious for the labor workers. What new technology will take over another family's job? We already have phone that follow our commands by simply talking into a mic. Instead of trying to advance why don't we all take a break and enjoy what's left of the natural state of life.
I found "Why Some Civil War Soldiers Glowed in the Dark" to be a very interesting article. Many people automatically assume that bacteria is bad. Lumped together with parasites and viruses, many are under the assumption that bacteria is always harmful. Like a live vaccine infected with a virus, not all "bad" things are really bad. It's crazy to think that being infected with this bacteria helped wounds heal better than it would without. No one would think that an assumed harmful bacteria would actually kill all the other microorganisms around. It's so interesting to think that bacteria helped heal a wound. Medicine will never cease to amaze me.
I found the article about the 3-D printers outrageous. I have always believed in scientific advancement but after reading Sagar’s post, I realized this could be a bad idea. I agree with Sagar that this will cause unemployment which we already have enough of. The thing I don’t agree to though is that robots can be helpful by making factories and giving jobs to people. These factories only cause more robots to be made for the assembly line. Clearly robots are more efficient than human hands, resulting in what everyone knows as the dreadful unemployment. A perfect example of this is in a well-known book, “Charlie and the Chocolate Factory.” In this book, Charlie’s dad worked at a toothpaste factory which had a line of men screwing on the caps on the toothpaste tubes. That was until a robot, more efficient, less costly, and sleeker than the workers replaced them. Charlie’s dad was fired all because of technological advancement. Why do business owners do this? Why would they try to cause unemployment? The answer is they do it for the money. Like I mentioned before, robots are much more efficient. For example, it says in the article that it would only take 20 hours for these “3-D printers,” or robots, to build a house it takes many construction workers 4 to 6 months. A business man looking at the statistics would instantly choose robots over worker because more houses in a certain amount of time means more money. Robots are also cheaper. There would no longer be wages even though there would be an initial cost. Over time though, robots would be cheaper, and cheaper means more money. It is obvious that robots are better but isn’t there a better place for robots. If the world does not stop this robot frenzy, the world would soon look something like this:
“We do not need any humans to make any planes or cars or anything else for that matter in the factory. We make the factories so we won’t need builders. Houses, roads, hotels and more, we make them all and even the stores. We don’t need the humans to be the cashiers, because we are more advanced. We protect the stores from robbers of all types, humans and robots. We have robots that drive your cars and planes, no more pilots or chauffeurs are needed again. Not to forget that we can write books. No need for authors and their tedious work. We finish thing 2000 times faster and are probably smarter than our creators. In fact, we do not need to be programed by humans; there are robots for that too.” -Robot 31451627349
Soon the world once dominated by humans for many years will all go down the drain when our superior creations take over. I know it sounds crazy but all the current events with robots taking human tasks and becoming flawless hints at the fact that robots can ruin human lives. First assembly line workers were fired and soon to come are the construction workers when the 3-D printer comes out. Unemployment is not going to ever get better if robots keep taking over the jobs humans CAN do. I believe that humans should be doing all the things we can and whatever we can’t do, the robots should do. For example, humans should do work that is not painful and robots should be the ones going into the deep oceans and studying thing humans can’t ever possibly do. Another thing robots can do is go into outer space and collect information and leave the analyzing for astronomers. DON'T LET THE ROBOTS TAKE OVER!
In the article, "Giant 3-D Printer to Make An Entire House in 20 Hours" Rebecca Boyle pointed out an important concept that 3-D printers can make large objects such as airplanes and buildings. The idea of machine building my home or an airplane that I am traveling in makes me feel very anxious. Therefore, I am concerned about the quality of the items produced, and also with their durability. However, I think people should still play some type of role in major manufacturing like this because it is incredible to see such ideas develop and technology grow. Technology is beneficial because it can be applied to actual sized buildings for emergency housing or low-income structures and also print out customized luxury homes. Before airplanes, many people traveled by a train or a boat. Now airplanes have made accessing other parts of the world easier, faster, and more cost efficient. 3-D printing could do the same because it could help low income people or those in less developed nations. However, a negative side to this idea is if buildings are being created through a printer, then the people who usually build buildings would be out of a job. It takes special skills to run these machines, so construction workers would not be qualified to make 3-D printers, which would cause unemployement for the construction workers. Another negative aspect is the materials used to make these buildings would be wasted such as paper and plastic. Even though there are several pros and cons to this concept, we know that technology is expanding and developing each day and the world will soon be able to witness how great and helpful the existence of 3-D printers are.
In regards to the "Giant 3-D Printer to Make An Entire House in 20 Hours" article, I agree with what many others are saying. It's a great technology that could help reduce injuries due to construction and help produce more houses in shorter periods of time, but it also reduces jobs related to construction. It is yet another example of human laziness and it could lead to more unemployment. However, I agree that it is a very good idea to use it in the construction of buildings on the moon and Mars like the article states. Conventional construction work would not be able to be used there due to the fact that it isn't exactly easy to call a construction company and request a house built on another planet. Structures can be created in space with little effort on our part, furthering our capabilities of exploring the universe.
After reading "Giant 3-D Printer to Make a House in 20 hours",I felt like I was living under a rock. I didn't even know there were 3-D printers!!!!!! The benefits for using an advanced piece of technology like this is extraordinary. Everything from the time efficiency to work safety will be improved if companies actually decide to use this printer. Sadly, there will also be some major set backs. The most important is that many people in the construction field will lose there jobs. Construction was always one field that aided the country when it was having some financial difficulty. For example during the Great Depression, to create jobs, America employed people to build the Empire State Building, the Hoover Dam and countless other structures. Even if you look back a couple of years, Obama passed legislation to increase construction and road work around the country in order to create new jobs.I guess everything has its pros and cons and these are the problems we will have to deal with as technology continues to grow at such a rapid rate.
I found the article about the diving very interesting. I did not know how much strength and power is needed to preform a dive. I know that they have to put a lot of power into the dive and do the correct movements to land in the water at as close to a 180 degree angle as they can to get a perfect dive with no splash, but even with that, I am shocked that it does not hurt them when they enter the water, falling at the speed and height that they jump from. You really need to have a stronger upper body to be able to dive from a 10 ft. platform and be able to enter the water. It was also interesting to find out that the temperature of the pool can impact how much it hurts when the diver lands in the pool. I'm surprised at how much strength you need to be able to perform a dive, along with the flexibility needed.
I found the article on olympic diving to be very interesting and answering some of my questions that I came across while watching the event on T.V. this past week. The comentators kept referring to the fact that each diver entered the water at a max rate of 35 mph. When Brown mentioned that she had to tape up her wrists to keep from injury I also remembered a story of one of the American divers saying that every night she had to wear braces and wrist guards because of the effect of her impacts into the water. As Lea said it shows how the divers need to have strong body to be able to attempt dives safely.
Brown also mentioned that in a diving pool they tend to warm the water to lession the surface tension. I know one of waters biggest charactoristic is cohesion where the water particals will stick to each other with hydrogen bonds. When heated up the particls will move faster and have less of a chance to form the hydrogen bonds.
Who knew science could be found even in diving?
Although the idea of using giant 3-D printers to make houses is intriguing, I don’t believe it would be entirely beneficial. In this economy, our biggest focus should be on reducing the amount of unemployment. It would truly be a mistake to allow these printers to replace builders, electricians, and other workers. These workers depend solely on the struggling housing industry for employment. If we take their jobs away, what other jobs will they be able to find in this poor economic state? The article also mentioned that these printers could be used to create buildings and facilities on Mars and the moon. However, I don’t think that planetary exploration should be our primary focus when we can’t even help our own planet. Just because we can create this technology doesn’t mean we should use it. Currently, people aren’t even that interested in buying houses so why should we work to make the housing system more efficient?
3d printing an entire house in 20 hours is extradonary. Just imaging your house growing from bottom up in a day. An advantage of 3d printing is that they can make incredibly complex structures ordinary machines or people can't, allowing for stronger and lighter products. Housing prices would drop, and maybe the day will come when you can buy a house for $100. Regarding the issue of losing jobs, I believe the idea of economy is becoming obselete. In only a few decades, machines will literally be doing all the work, leaving everybody jobless. How will money work then? The only way is to abandon the idea of currency and accept that humans need to live mutually.
It is always interesting to hear about various organisms and how they affect history. Diseases in particular can traumatically impact events in history. Fortunately for the soldiers, the diseases negatively infected parasites that may have killed the soldiers. Additionally, the fact that the connection was made by high school students is very fascinating.
The three-dimensional printers are very interesting. In the article, it mentioned that it could possibly be used in order to construct structures for the colonization of the moon or Mars. However, the materials that the printer uses would either need to be created at the site or transported with the voyagers, and the printer itself would need to be brought and assembled at the site.
The mechanics of diving are certainly useful. By understanding how our bodies work, athletes can potentially increase their level of performance. Personally, I can’t believe how fast they can be descending.
Reading the article "Giant 3D Printer to Make An Entire House in 20 Hours", I was shocked yet pleasantly surprised. Even with the advancements that science and technology have presented society with, I never expected that something so prolific would have been created so soon but I was happy that scientists have figured out a way to create houses in a short amount of time compared with how long it normally takes to build a house. But while there are many benefits, there are also drawbacks, as with everything else. With the economy being in the state that it is, can we afford to replace construction workers and laborers with technology and increase the unemployment rate when we are struggling to find jobs as it is? Technology is advancing and enabling us to make our lives much simpler but at what cost? Would mass-producing houses further damage our economy? Environmental concerns should also be considered; if houses are produced at a much faster rate, how much damage would we be doing to the land and trees around us? The country as a whole has already undergone plenty of development. Although I think a 3D printer would be beneficial, I also believe that the negative aspects outweigh the positive.
We can learn a couple of things from the article, "Why Some Civil War Soldiers Glowed in the Dark." Some of those things are like the importance to be well-educated in all areas of school, and the importance of learning about life which the dentition of Biology. The reason why I chose to read the article as it combines two of my favorite subjects, history and science. This shows how all subjects that we typically learn in school are interconnected hence it is vital to specialize in these fields of studies. In addition, it is important to study microorganisms as it is the key to answer man question that seemed impossible at the time. When Bill and Tom carried out the experiment indicating that the Photorhabdus luminescens were responsible for the glowing that saved many peoples lives during the Civil War. It opened a new realm of possibility which seemed before impossible. Using what we learned about this bacteria, we can create an "artificial bacteria" that can kill pathogens which can severely hurt us. Is this in the real of possibility? Yes. Is it practical or what can we do to achieve this? I will leave up to you. To briefly sum it up, learning about how life works on earth can lead to magnificent discoveries and cures to practically incurable diseases. In addition, this shows how biology and the scientific method can be applied in our lives today.
After reading the article, "Why Some Civil War Soldiers Glowed in the Dark," I could not believe how much information Bill Martin and his friend were able to obtain on their own. By acknowledging his mother's work on the glowing bacteria, P. luminescens, Bill was able to make the connection between this bacteria and the glowing wounds on the civil war soldiers: a connection that apparantly no one else was able to make for a hundred and forty years!
Furthermore, he made this dicovery at seventeen years old with probably no scientific background on microorganisms and bacteria. Moving forward, I was highly interested by how P. luminescens and nematodes not only had the abiltiy to make the tissue in the wounds glow, but also were able to fight off other infectious pathogens and germs and essentially save the glowing soldiers' lives. It makes me wonder about how many more soldiers would have died if it was not for these bacterium. Perhaps if these little life-saving organisms had not been present at the battlefield, we would all be looking at a different outcome for the Civil War.
In response to the article "Olympic Diving Physics," I never knew so much science was involved in the sport of diving. I knew there was some physics involved with the amount of force needed to push off of the platform, but never imagined ever flip and step needed intense practice and understanding of the physics involved with these flips and steps. For example, when a diver is jumping off the platform/springboard he/she might go into a tuck position to gain speed while flipping while their feet are still on the platform. By putting energy into the board, the energy then propels the diver up and away from the board because of Newton's Third Law of Motion. The "rip" entry looks very difficult to execute and even more so to master, as even more agonizing practice must go into this peculiar entry into the water. I believe I have only seen the "rip" entry once or maybe twice before in the Olympics over the years.
The article about glowing bacteria is so fascinating. When i was first reading through the article and saw that the wounds on soldiers started to glow, i got a little suspicious. This must be something bad! Later as i was reading i read about how the doctors said that these glowing wounds, were actually a good thing! Bacteria is commercially broadcaster as something bad. For example,things like hand sanitizer say "kills 99.9% of bacteria." We are so used to seeing bacteria as a bad thing that when I saw an article like this I was even more interested! As i was reading, I started t question the part where the article said that this bacteria cannto survive in normal human body temperatures later to find that when the soldiers might have gotten hypothermia the bacteria could easily survive. Who knew this glowing bacteria could be a good thing! It's even more interesting to see someone so young, so interested in this topic that they could win a competition with the research and experiments they led!
After reading "Olympic Diving Physics", I was truly amazed. Watching the Olympics, the divers made it seem like diving was no big deal: just take a deep breath, bounce off the platform or springboard, do the flips, and go into the water! No big deal. But behind it all takes the skill and and accuracy to go in without splashing. Before this article, I had no idea what speed divers dived at and how one could injure himself/herself because of the water pressure and surface tension. 35 miles per hour is pretty fast going in to the water. And if divers land wrong, it would hurt for sure. From this article, it's pretty evident that everything in the sport of diving matters. From the "approach" on the diving board to how a person flips, and the timing of it all. Also, from watching the Olympics this year and this article, I learned that when diving, divers need strong shoulders to push through the water. The line "Diving is all about lines and form" is the aesthetic part, in my opinion, because that is where the actual dive comes from and the "lines and form" determine if there will be a splash at all.

The idea of a 3D printer to create houses and even building is extremely innovative; however, I do not think that 3D printers at this time would be beneficial for the economy. At this time, the United States is still recovering from a serious recession and a 3D printer used to build houses would be taking work away from a lot of construction workers and factories. Factories that create machines that are used in building houses and buildings, such as cranes, would have a difficult time surviving in this economy. I think this 3D crane would be extremely beneficial in space. Since, humans cannot be in space for very extended periods of time, the 3D printer would help to expand space exploration. We still might be very far off from installing a 3D printer on the moon or another planet, but it is an idea that will be worth it.
My dad once told me that during his adolescent age, there were no televisions, cars, or computers up until mid way through his teenage years in India. He considers internet one of the world's greatest wonders. After hearing how it was for him during his younger years, I am also awestruck by the human advancement in the past years. Teenagers today consider these electronics as a part of the world, as if they were here forever. I and many other teens do not realize how much the technological field has progressed through the past 20 years and rather take these electronics for granted. After reading "Giant 3-D Printer to Make An Entire House in 20 Hours", my eyes opened at how much we are moving forward. We are soon to have machines printing houses out in what is relatively to modern construction time the time it takes to snap your fingers. I was thoroughly impressed by the fact that the electrical wiring and other technical areas will also be handled by a machine. Sure this may or may not cause for less labor which may lead to lower job opportunity. To me, this is one of the amazing technologies that came about in my life span, just like the tv and the computer came about in my father's.
Sorry for the relatively late comment. I did not get the chance to use a computer in the past few days.
After reading "Giant 3-D Printer to Make An Entire House in 20 Hours", I was shocked to see such an advancement. Personally, I don't think this is a beneficial idea. Many Americans are unemployed, and if this development is to be carried out, then many more people would lose their jobs. There are so many people involved with building any type of construction. If a 3-D printer were to conduct all of the necessary steps to build a house, then unemployment will rise, making the economy weaker. The house itself may not be secure against weather changes, such as snow storms and thunderstorms. If this 3-D printer house cannot withstand weather changes, then what is the use of it? But I do believe that these printers will be useful in establishing houses and buildings in emergencies. If a hurricane or a flood affected an entire area, then the 3-D printers should be used to aid those in need. For right now, I think that scientists should leave the construction to the people, and not the technology. At this time, they should help with the economy, not hurt it.
After reading “Why Some Civil War Soldiers Glowed in the Dark,” I pondered over what amazed me more – the fact that luminescent bacteria saved soldiers’ lives in the Civil War or that the source of the glow-in-the-dark wounds wasn’t discovered until almost 150 years later by two high school students. But it sure is intriguing that the bacteria, Photorhabdus luminescens, happened to be in the realm of the high school student’s knowledge since his mom was a microbiologist & just one simple question resulted in a major discovery. I had read somewhere that nematodes have tubular digestive systems, basically making it easier from them to puke up the bacteria inside, because the tube has two ends. They are found almost everywhere, from soil to ocean floors, and there are over 27,000 species of nematodes that we have discovered so far. It just goes to show that open wounds are especially dangerous and should be treated immediately because these bacteria are ubiquitous, and the wound can get infected effortlessly. Yet it amazes me that the one thing that we all prevent from going into our bodies can end up saving our lives. The bacteria probably killed off the other pathogens trying to enter through the wounds; as a result, it saved the soldiers from death due to infection. Furthermore, they even cleared out the immune system, allowing the soldiers to return to perfect health. I wonder, if further research can be done on this specific species of bacteria, possibly even altering it, to be a helpful immune system cleanser.
When watching the Olympics I was always interested in the diving portion of the games. The one thing that caught my eye was why judges would reduce scores due to splashing. This article explains in full that " The Rip Entry" is the core of the score. Judges look that the diver's hands are perfectly perpendicular with the water. This must take quite a lot of technique and skill. Also, it was interesting to read that the divers perform their dives into bubbles when training. As much as I try to run away from Physics (wasn't my best subject), I realize that this subject is EVERYWHERE. Teachers would be happy to note that once the term "Newton's Third Law of Motion" rose I was able to define it right away. It makes sense how this is put into diving terms. A fiver's "work"is done on the diving board by butting energy into the board and a diver harness the "equal and opposite". It all makes sense now!
The article about 3-D printers was very intriguing to read. It is almsot stunning that technology is being devoloped so that a complete would be able to be made in 20 hours. It is hard to believe how advanced this technology is, it was almost as if I was reading a SciFi story. One negative aspect is that normal housing projects that normally take six months can now be finished in one day without many jobs or labor. Although I do agree that this machine will take away from our jobs and have a negative impact on our economy, it is also true that the machine can be used in more beneficial ways and can be very helpful. The article mentions that this machine could be ideal for emergency housing also. Imagine if this machine was available after hurricane Katrina.
In response to the article "Giant 3-D Printer to Make An Entire House in 20 Hours," I was surprised that something like a 3D printer even exists. I thought a cure for the common cold would have come quicker. Anyway i think something like a 3D printer can be both beneficial and detrimental in equal ways. For example building a house in 20 Hours is amazing. Think about how useful this would have been during Hurricane Katrina. Hurricane Katrina destroyed around 275,000 houses. New replacement houses would be built quickly and less people would have to stay in the Superdome or the New Orleans Arena. Also a machine like this would help us build labs and facilities on the moon or mars. On the other hand, one can only think about how many jobs would be lost to a machine like this. Unemployment is at an all-time high and building robots that get rid of jobs isn't the right idea. In the future I believe that a 3D printer should only be used to build facilities on planets and moons, and for emergency housing.
Although initially daunted by the lengthiness of the article, I thoroughly enjoyed reading "Why Some Civil War Soldiers Glowed in the Dark." With additional historical background, I was able to conceptualize the P. luminescens bacteria more clearly. It's ironic how hypothermia, which enabled the P. luminescens to kill off the pathogens in the soldiers, actually saved lives for once. Like the remora, as seen on Shark Week(a suckerfish that normally acts as a parasite), attached to the belly of a shark (remora eat away bacteria while traveling with the shark), this "Angel Glow" shared a beneficial symbiotic relationship with its hosts. I do wish the article went into more detail about the bio-mechanics of how bacteria become bioluminescent, however it was still a very interesting and educational article.
"Giant 3-D Printer to Make An Entire House in 20 Hours”
Before reading this article, I would have never thought houses could be made using something as ephemeral as 3-D printing technology. It terms of efficiency and cost, 3-D printing seems like a liable option for house building. However, how sturdy are these houses? Are they meant for long term homeownership? If anything were to go wrong, will the house require special parts and materials in order to be repaired? These are few of the questions that may arise when putting an idea as hypothetical as this to action. Another issue that will arise is the decline of good old-fashioned american labor. If entire houses, not to mention buildings, are built with the use of printers, many middle-class americans as well other blue-collar workers will be jobless. We would be facing an economical issue similar to that of the industrial age.
The article about a house being made from a 3-D printer very fascinating. It is a great advancement in technology and should be viewed as a huge accomplishment. However, to be honest, I would not want to live in a house solely built by a printer. As for the jobs that people say would be lost, I completely agree. I understand that as our world advances, technology will obviously be relied on more for creating or perfecting things, but technology shouldn’t be fully relied on to build something as important as a house. It shouldn’t be something that creates the house; it should be something that helps the contractors with the creation. People who have a part in building houses will be replaced by a printer, leaving them unemployed. This printer may help speed the house-building process; however quality should always be more important than quantity. The printer may be more efficient, but what would happen if something didn’t go as planned? These are just some things to take into consideration before letting a 3-D printer build a house you may live in in the future.
I was very amazed by what I learned from the article "Why Some Civil War Soldiers Glowed in the Dark." It was interesting to learn how nature can produce such a coexistence between organisms, such as the nematodes and the P. luminescens bacteria, that could create a medical miracle that saved so many lives. It is amazing to find that two organisms could join together to "infect" a person and the bacteria could actually help heal a person. Discoveries such as this one can help postpone the effects of bad bacteria and are the catalysts for medical advancement. The P. luminescens is proof that all bacteria is not bad.
I found the Olympic Diving article very interesting. As a springboard diver myself I know firsthand the importance of using the board to propel yourself into the air. If you do not ride the board before jumping off then you will not have enough time to preform intricate dives along with twists and flips. This would result in you crashing against the surface of the water, which hurts...a lot. One thing I did not know was that the temperature of the water affects your impact. This makes sense considering that heat causes particles move faster thus lowering the degree of surface tension. One thing I did not realize is how fast platform divers are moving. They have to be very strong to withstand that amount of force. Their upper body has to be able to break through the water to create the desirable rip entry. Diving is very difficult as you need to use every muscle in your body to preform seeminly effortless acrobatics with perfect technique.
I believe that 3-D printing wouldn’t work well for building regular homes, but does offer great opportunities for building homes in third world countries and low-income housing. Though it takes away jobs in the carpentry industry in offers more jobs opportunities that deal with the production and transport of concreteUnions most likely would fight against 3-D printed homes because they require less people to build and less time being paid to build them. Also, from a aesthetic standpoint I don’t feel concrete houses would be that popular. The average suburban family in the North-East isn’t looking for that style of house. In Florida and the South-West concrete hacienda style houses are already commonly built. 3-D printers offer a more cost effective way of building them. Due to housing bubble and economic downturn there is no shortage of cheap mass produced suburban homes.
Though I feel there is not much demand for 3-D currently as the new style of suburban homes, they do offer opportunity for low-income families and third-world countries. Concrete is a relatively cheap building material, less workers means less for the cost of labor, and quick building also lowers the costs. Transporting and assembling the printers may prove difficult in under developed areas without proper roadways. By keeping the costs low the price of the homes could be covered by charities or even the homeowner.
Intuitively, I was very fascinated with the idea of a 3D printer, a machine, building a whole entire house in as little as 20 hours. The advanced piece of technology will definitely prevent delays,work related injuries and other labor issues because of the speed and accuracy with which it has the potential to build houses. Using 3D printers to build entire houses will undoubtedly be economical and beneficial in the sense of efficiency and cost because it can build many houses in such as short period of time- causing the price of houses to significantly decrease. But in the financial situation that America is in today, all the construction workers and developers will lose their job- making the unemployment rate even higher. Additionally, even though it is an understatement to say that technology is evolving at such a rapid rate to a point where it is extremely precise, I would much prefer to have and live in a home that was meticulously put together with extra care by construction workers. To me, I would personally prefer to know that people took their time to build and put together a house, not a machine.
In Response To: Olympic Diving Physics
I found this article to be very interesting; however, apart from the 10 meter high platform, and the 35 mph water entry speed, I found that the "physics" or science involved were similar to that of other sports. For example, the physics involved in diving off a springboard would be similar, if not the same, to the that of gymnastics (i.e. the vault, or something similar to that event). Yes, there are a lot of different intangibles when comparing the two sports—the courage it takes to free fall from 10m up in diving or overcoming the nerves for 25m sprint down the "runway" before vaulting. But, when it comes to the actual physics involved during the launch from the platform and the jump off the board and vault over the obstacle, it's mostly the same (the difficulty given the circumstances might make one sport arguably harder than the other). Yes, physics is involved, more than one would think, in diving, but in every other sport there is just as much involved. The only difference is that the rules, location, and people are different. In other words, the equation is the same, only the value of the variables are different.
“Giant 3-D Printer to Make An Entire House in 20 Hours”
I heard about 3-D Printers a while back, while looking at a short segment on National Geographic where physicist David Kaplan, replicates a crescent wrench using a 3-D Printer. The real amazing feature of this new invention is that it can replicate moving parts. By placing an object underneath a scanner and highlighting its movable parts on a computer, the printer is able to replicate its practical uses as well, such as tightening a bolt. Although the recipe for the printing material is a company secret, they say its durable as concrete. One could only think about the possibilities of this new printer. There would be more affordable structures, easy emergency housing, and even luxury models. My only question is if they were to make these houses on the moon, how would they replicate them? Would they scan an entire house or would they create smaller scaled fully functional house and enhance the size on the computer. Although some may say this may be a threat to employment around the country, we should realize the importance of advancing technology and welcome it. It’s like saying that we shouldn’t have created the pick-up truck, because we could hire more people to carry supplies from one place to another. We shouldn’t be afraid of new inventions that could change our lives for the better.
The article "Giant 3-D Printer to Make an Entire House in 20 Hours", really opened my eyes to how advanced we are becoming. I never imagined that a machine could build an entire house all by itself. A ton of work is put into manually creating houses, and to think that we are working towards creating machinery that could complete all the work in less than a day, is just phenomenal. These giant 3-D printers will speed up production, and lower the amount of manual labor needed. However we shouldn't let the machines do all the work, because then many people will be out of a job. The giant 3-D printer can create wonderful possibilities, yet also come with disadvantages aswell.
The article "Why Some Civil War Soldiers Glowed in the Dark" was very interesting. It showed me that anybody can discover something amazing if they ask the right questions. I also found it interesting that the bacteria Photorhabdus luminescens can give off a slight glow and can actually save people's lives. It shows me that living things can have a wide variety of characteristics.
The article "Giant 3-D Printer to Make An Entire House in 20 Hours" also amazed me. It really shows how far we have come in terms of technology when you don't even need people to build a house now. I agree with Khoshnevis when he said that using the 3-D printer would be ideal for the moon or Mars. It would be the perfect way to create structures before we start going there.
3D printers are a very interesting and extraordinary invention. Building things such as airplanes and food is amazing, but building houses and colonies is astounding. Houses could be built more quickly and efficiently, and some time in the future, we could colonize some place outer space. I remember reading an article a year ago about Stephen King advising the world to build houses and colonize in space because of overpopulation. The chances of that happening are much higher as a result of 3D printing. However, this could be bad for many people who could lose their jobs. Unemployment rates could skyrocket if printing houses becomes successful. It will be interesting to see what the future holds.
In response to “Giant 3-D Printer to Make an Entire House in 20 Hours” I feel that though having this sort of advanced technology is great and exciting, we have taken it too far. We have continued to develop in ways which we don’t need to develop, and instead of using technology to make the impossible possible, we have used it to simply make things easier and faster. We as humans already have the ability to build houses, creating a machine to do the job for us are simply wasteful. Though having a 3-D printer do all of the work for us in a short amount of time sounds amazing, is it something we really need? Replacing peoples’ jobs with technology can be harmful in the long run, more and more are becoming unemployed.
After reading "Giant 3-D Printer to Make a House in 20 hours,” I was pretty intrigued. I had already known that 3D printers existed and what they were capable of, but I never imagined this. Making a house in 20 hours is a huge accomplishment with the use of a 3D printer. Knowing that we have technology that can build houses within a matter of hours is pretty surprising. Having this technology is very beneficial because its “safe, reliable, and affordable.” This would make more people want to buy these types of houses, which would boost the economy. Also, these houses are going to be made in a short period of time which is definitely a positive thing. On the other hand, having 3D printers would decrease the number of jobs available in the construction industry, which would make more families unemployed. If technology is progressing like it is now, then within a few decades we will have robots and other new technology doing our work for us. This being said, is too much technology really a good thing?
The article "Olympic Diving Physics" gave me a whole new perspective of the sport. Before reading this article I had no idea that physics played such a huge role in this aesthetically pleasing event at the Olympics. The fact that the way one walks on the board the motions one should go through while on the board showed me how meticulous and critical the sport really is. During the Olympics when I was watching the platform event on TV I was so amazed that the divers made such a small splash in the water because they were jumping from such a high platform. During this event I heard the commentator say that the splash is controlled by the form in which the diver heads into the water. Also while I was watching this event the way the divers created a hole (which in the article was stated as being a rip entry) in the water with minimum splash really amazed me , and the article stated that many of the times the divers are going in to the water at about 35 mph! Creating such a small splash when one is hitting the water with that much speed is incredible. All in all this article showed me how truly brilliant and difficult this sport is to master. One has to understand physics very well because it plays a key role in the techniques a diver uses to create an aesthetically pleasing dive!
I found the article entitled "Why Some Civil War Soldiers Glowed in the Dark" to be quite amusing. It's one thing for some organisms to have the ability to glow, but when they are inside humans and are able to make people glow in the dark as well? Now that's pretty cool. What's even cooler, is the fact that glow in the dark bacteria using humans as a host, may have even saved some soldiers' lives. The P. luminescens bacteria, which most likely seeped into the wounds through soil, used chemicals that made them glow, to kill of bacteria that was infecting the wounds of the soliders.Most people view bacteria as a bad thing, but in the case of these soldiers it was a good thing. It's amazing how somthing so small, could have such a big impact on so many people.Another thing that interested mewas the fact that sevral soldiers mentioned the glowing, but it was kind of just passed off as folklore until this student asked a question. As Dr. H mentioned, this article shows the importance of asking questions.
I found the article “Giant 3-D Printer to Make An Entire House in 20 Hours” to be extremely fascinating. The intriguing and complex idea demonstrates how quickly our technology is advancing to benefit society circumstantially and allow for science to delve into greater extremes never before imagined. Although it seems like a great alternative to building on a time conscious basis, I don’t think it will be able to create quality products since it is simply mass-produced by a machine as opposed to the intricate handwork of actual workers. Also, I don’t believe it is the right time to employ this major type technology at the current economic state that our society is suffering from. At the moment, our major concern is reducing the amount of unemployment that many families are facing due to the poor economy. Many people are losing their only source of income and as a result are scraping by on a day-to-day paycheck. Implementing this type of technology would take away the jobs of builders, printers, manufacturers, electricians, and construction workers. All of these people will lose their jobs as a result to this massive technology advancement in a time where they solely depend on it to provide for their families. Additionally, the article mentions that these 3-D printers will allow us to construct structures and laboratories on the moon or mars. Even though this may be a beneficial step toward the exploration of space, it should not be our world’s main imperative. First we must tackle the planet that we actually live on as opposed to a foreign, unattainable habitat somewhere in space. If we can’t create a sustainable, easy way of life on Earth, how are we going to build one on other planets that don’t even provide the essential oxygen needed for survival?
Wow, open heart surgery really is something of magic. After reading the article of the woman with an aortic aneurysm, I was blown away with the entire process of open heart surgery. Step by step she explained her day in detail. It was incredible how calm she maintained just sitting in the waiting room, knowing she was only minutes away from having her chest ripped open. After going into surgery, she explained what her surgeons had to do step by step. Coming from an ordinary woman. The process seemed quite simple. Her heart needed to be stopped, the root of the aorta had to be removed and replaced, and than it had to be set back into working order. In my opinion, the scariest part of the surgery is definitely being put on a bypass machine. Knowing a man made machine is keeping you between life and death is simply incredible. However, its the humans who perform the real magic. These surgeons were able to use a piece of synthetic material to actually replace the root of the aorta for more than a lifetime. Because of these incredible people the woman was able to tell of her incredible story.
After reading the article, "Why Some Civil Soldiers Glowed in the Dark," I realized how "caring" nature can be with its own antibacterial remedies. One such remedy, that was "unintentional" and was made famous during the American Civil War in Tennessee, was the Photorhabdus luminescens (P. luminescens) bacteria. After the Battle of Shiloh in 1862, more than 16,000 soldiers were left wounded (along with more than 3,00 dead) in the fields and forests of battle. Sure their were army medics and doctors, but some wounded soldiers had to sit through 2 rainy days and nights with dirt and shrapnel in their moist open wounds before they received medical attention. During this time, soldiers that had received the "Angel's Glow" (wounds that glowed) were more likely to survive than others. Bill Martin and John Curtis did an experiment to find out what could have caused this glow. After research, they found that P. luminescens could have been the cause of this glow. P. luminescens shares a symbiotic (perhaps mutualistic) relationship with nematodes. For food, nematodes take shelter in the blood vessels of insect larvae. Here they puke out the P. luminescens bacteria that kills microorganisms and other living functions in and of the larvae (insect). This allows both the P. luminescens and nematode to eat the larvae and then move onto another insect larvae. Therefore, P. luminescens could have gotten into the wounds of soldiers through the soil and used the chemicals they possess to kill any pathogens/microorganisms in the wound. The wound would've provided suitable conditions for the bacteria because it likes cooler conditions and the cool weather/ rain helped to lower soldiers' body temperatures. Based on this article, one question I would like to ask is if their are any other species of life that help cleanse an open wound....
The article, "Olympic Diving Physics", is very interesting because it is amazing how some people can flip and twist in a variety of ways into the water. Some people may not consider diving a sport, but they haven't tried it themselves. Divers must be precise with every dive into the pool because it can cause harmful injuries especially from higher platforms. It is one thing to drive 35 mph but it is another thing to dive into a pool at 35 mph from a 10 meter platform while flipping and twisting all at once.
After I read the article about the bacteria in the soldiers’ wounds, the first question that popped into my mind was, “How is it possible for the bacteria and nematodes to travel into the wounds and complete their whole cycle of digesting and glowing so quickly? The men battle for a few days and then get treated afterwards.” I know that in the Civil War era, the health care field was incomparable to that of today, but I wondered just how long it took to treat all the people. The article says men were in the rain for days which lowered their body temperatures and made a good home for the bacteria and nematodes. Moreover, they generally stayed outside even when they waited for treatment. So I can gather that the worms were quick movers and quickly infected the host bodies. And although the human immune system could eventually get rid of them, surely the soldiers were not in top health and their bodies did not have enough nutrients or strength to clear them out quicker. Thus, over time the bacteria have “a chance to show off its glow.” The article also describes the relationship between the nematodes and the bacteria. I think it is mutualistic because when the bacteria are clumped and glowing, they attract other insects for the nematode to eat. The nematode eats the bacteria as well, but gives them a perfect breeding ground to repopulate in its stomach. Then they get pushed out and attract insects again; both sides benefit each other in this relationship.
I think it’s just great that divers can practice diving into bubbly water. The aerator generates bubbles to break the “flat, hard” surface of generally still water and the diver is cushioned in a softer landing in case he or she messes up. However, a free falling diver going from 10 meters hits the water at around 35 mph and accelerates at 32 feet/second before hitting it. That seems so scary, falling head first at a high speed, and as the author of the article said, the force causes some divers to break their stances and hit themselves.
On a last note, I think a similar rip entry effect could be achieved by jumping (from a high distance) in the pencil stance where the whole body is perpendicular to the pool, but just feet first. Then as you hit the water, you move your feet apart, like a diver moves his hands.
The diving article was great, and it's ridiculous the amount of courage the divers have to do this over and over again. My stomach nerves tingle at the thought of entering the water at 35 miles an hour. My favorite part of the article will was applying what I read to observing the videos. Halfway through the article I got sidetracked on YouTube for a good five minutes marveling at the twisting dives and minute splashes. Watching the divers during the jump shows how detail intensive diving is and how one misstep can screw the whole physics of an entry up.
I found the article about those glowing wounds during the civil war very intriguing. I have never heard of glowing wounds before. It was very interesting to read about how the scientists discovered how there wounds glowed. I love how such an amazing biological event can exist all the way back then and still lead to a great discovery today. This was such a rare and unusual condition that it was given the nickname Angel's Glow. The scientists gave a very well written explanation of under what conditions the glow needs to occur.
The Giant Printer Article caught my attention immediately. I have a great interest in architecture and design and it’s amazing how technology has advanced this much to create one of man's first idea of a shelter which would take weeks and compressing it into as short as 20 hours. This technology is good for what the article mentions, emergency houses and cheap shelters but I’m not so sure about complex homes with the necessary plumbing and wiring. This instrument is a good start for a structural outline but the details needed for a luxury house is all up to us. None the less if this printer exist and works it would be a phenomenal aid for construction workers and architects using them as tools such as CAD, mistakes can be corrected precisely and more safely. I’m not sure how this printer may operate in zero gravity and how it could form the desired shape of the concrete without it going in every direction, or having it freeze instantly and crumbling before the building can form, but the final frontier is till another time. The current possibilities can revolutionize how we operate ourselves during construction and how we think about architectural design with new and evolved forms.
"Giant 3-D printer to make an entire house in 20 hours" After reading the article it was shocking to see how far technology has come and now we have 3D printers that can not only make houses, but on Mars. 3D printers can save a lot of time in making houses which can hence save a lot of money. However, the printers would cost many people their jobs and the unemployment rate will increase. So, we should focus on making more jobs for people instead of taking them away. Even though the 3D printers have advantages, I do not believe it is worth the jobs of many architects and the risk of the economy becoming worse.
The Giant 3d Printer article is very fascinating. It is amazing to see how far technology has come. Yes, it is a good thing, because everything would be more efficient. But also, this printer would cost people their jobs, and everyone knows our unemployment rate is already pretty high.
After reading the article about glowing wounds, I was surprised to find out that microorganisms were helping the soldiers. Back in the times of the Civil War, usually anything that happened to wounds wasn't good. I didn't expect to learn that sitting in the mud and rain for two cold days actually helped them. Even though most microorganisms have no affect on the human body at all, it is interesting to know that those that do affect us can do more than just harm us. Despite their being prone to infection, in this case the soldiers were eventually saved by bacteria. Although the soldiers weren't saved by angels, their specific environment and conditions which made it possible for the glowing bacteria to live at all, is somewhat of a phenomenon.
Response to "Why Some Civil Wat Soldiers Glowed in the Dark": I found this very interesting that bacteria could do this. Normally, when people think of a wound having bacteria, they automatically assume that it is harmful. It actually saved their lives though from more harmful bacteria and diseases. I was shocked to learn that it wa possible for the wounds of the soldiers to glow. Are there any current cases that this happens with now?
After reading the aricle,"Giant 3-D printer to make an entire house in 20 hours" I was really amazed by how fast technology is advancing. I really find this type of technology to be a great deal of help because now houses can be built faster, easier, cheaper, and safer. With this technology buildings can be made without the cost of people's lives. This technology can be a great deal of help to poor communities and countries around the world becasue we can now build homes faster and cheaper which allows the poor people to be able to buy homes too. This in turn, will reduce corruption and other evils in poor communities and countries because everyone will be able to afford a home. All in all, I strongly feel this technology can benefit our society today.
Growing up I have always had a gigantic imagination. If I didn’t get what I wanted, I wouldn’t cry like other kids. Instead, I remember wishing I had the copy machine that a cartoon character Timmy Turner had in the Nickelodeon show “The Fairly OddParents.” The copy machine that Timmy’s fairy god parents granted him could make a real life copy of whatever picture he wanted.
After reading “Giant 3-D Printer to Make An Entire House in 20 Hours”, I am flabbergasted. I still cannot believe that something I thought could only in a cartoon is close to being a reality. Although this is exciting, a giant 3-D printer has both pros and cons. This invention could be advantageous in building animal shelters, homeless shelters and other government funded buildings. These buildings would cost less money to build because laborers wouldn’t have to be paid; thereby also reducing the amount people spend on taxes. A negative aspect is that a lot of jobs would be lost in an already bad recession. Another con is than there would no longer be beauty in architecture. Everything would look mundane and boring. I can’t speak on behalf of others, but I know that I would miss seeing the aesthetic creations of dexterous architects such as Flank Lloyd Wright’s Taliesin.
I personally like the article on the 3D printer. I have only recently heard about 3D printers and it was interesting to read more about them. I was amazed at the fact that with the technology that we have now, we could potentially build a house within 20 hours compared to the long, arduous six months it usually takes. But although 3D printers could lower the prices of houses, I personally do not like the idea of living in a house that was made by a machine opposed to one that was crafted by people.
The article on the P. luminescens bacteria surprised me in many ways. I was shocked to learn that a reason for the luminescence on soldiers’ wounds was not determined until recently. This probably became common during other wars near that time, so I’m surprised that no one was able to find out before Bill Martin. This shows how asking questions can lead to something amazing. In school, teachers always say it’s important to ask questions, and this discovery is another example of how this is true. Bill Martin could have just thought it was a myth that wounded soldiers glowed and not have asked any questions. If he had done that, he wouldn’t have solved a hundred forty year old mystery. The helpfulness of the bacteria could possibly lead to expanding the use of microbes for medical uses.
It would have been helpful if the article explained why the bacteria glowed. Also, I did have one question after reading the article, and it was whether another bacteria species could have caused the soldiers to glow. I wondered what caused Bill Martin and Jon Curtis to determine that it was P. luminescens and not any other bacterium.
After reading about the glowing soldiers i was astounded. I am a history buff so this was 2 times as interesting for me. First of all the civil war is a very rich part of our country's history. It seems like so much happened during it.
This is just one more thing that is so interesting. First of all these people were glowing, that is amazing i mean the chances of that must be quite small. Even more interesting about t is that it is two cases of antagonism in one. i mean the soldiers were hosting the bacteria and the bacteria was hosting the glowing nematode. So the nematode killed the bacteria and was left in the soldiers cuts as it glowed. As a result of this the soldiers that were glowing had a better survival rate because the glowing nematode killed most of the bacteria.
This really show how small organisms can get i mean these nematodes are to bacteria as bacteria is to us. There is always something to delve into further and to ask questions about.
I had never thought about the idea of making houses differently until I read the "Giant 3-D Printer to Make An Entire House in 20 Hours" article. It surprised me that we even had the technology to do this! The fact that we could do this in 20 hours amazed me. While we could save time, I feel like there are many negatives to this idea. For example, would it be as trustworthy as doing it manually? When people do it by hand, we can see the mistakes that might have been made and correct them. Also, the idea of more unemployment is not good. New Jersey itself has a 9.8 percent unemployment rate. What would people do if even more jobs were cut because of this? While it would be good for hurricane victims and for emergency housing, would it be good enough to stand? I would not want to live in a house made by a 3D printer. I dont think I would totally trust it. As good as technology is, it always has room for error.
I was surprised when I heard about the 3-D printer, I didn't know such a thing was possible! For me a 3-D printer seemed far away into the future, I didn't realize that in fact, it was not so far away after all! These kinds of innovations can lead to huge things, slowly man has furthered technology and efficiency. Imagine what we can do with a 3-D printer! The faster we can build buildings the more man can do in a shorter amount of time. Not to mention that the cost of human labor will be saved. In the future when we want to build colonies on Mars think of how helpful this tool will be. We would not need manual labor to do the job, which would be very helpful because manual labor would take time, and the workers would have to go through many hardships. Using the 3-D printer for such a task would be very efficient and would not take long to do which is always best for creating houses on a lifeless, hostile planet. With this invention it seems that it could play crucial part in establishing colonies on distant planets. Our world just keeps getting better and better with the amazing inventions human beings are capable of creating.
These kinds of inventions spur the economy. Innovation increases automation which results in higher efficiency and productivity as I stated in the previous paragraph. Both efficiency and productivity have huge parts in our economy.Productivity and economy contribute to a nation's GDP (gross domestic product), meaning at the end of the day how much a country produced in terms of goods and services.
