Week9_Zombies!

Monday, March 9th, 2009

This week we learned about the interesting field of nanotechnology. We discussed how nanotechnology concerns many fields that involve objects of extremely small size. Wikipedia describes nanotechnology as dealing with structures of 100 nanometers or smaller. In class we went over many example of nanotechnology including the iconic Bucky ball and how chains of carbon can be used to create structures. The applications of nanotechnology are interesting and can be extremely helpful for us. A good example is nanobots that can identify cancer cells and then kill them off, effectively preventing the serious effects that they have on the body. Another example is the creation of nanotubes made from carbon. These tubes are very strong, strong enough to build the fabled space elevator. It is applications such as these that make nanotechnology one of the more important fields of research currently. However, with good things there are always bad things as well. Nanotechnology could also be used to create harmful things.

Resident Evil is a series of video games and films that deals with an apocalyptic scenario in which a virus called the T-Virus breaks out and infects the world. This virus degenerates the living and reanimates the dead. Organisms are infected by being bitten or scratched by an infected organism, making it very easy for the virus to spread. Taking into account the amount of dead existing in the world, the chances of survival against the virus are virtually zero. Also prolonged exposure to the virus mutates the body of the organism further and creates monstrosities. This sounds like a normal zombie movie however the explanation of the creation of the T-Virus is the intriguing part. The T-Virus was created by a clandestine team of three researchers by combining an unnamed virus that they found with the Ebola virus. This virus caused rapid mutations. It was meant to be used for medical purposes because it showed signs of regenerative capabilities, however when one of the researchers died, the other two thought of exploiting it for money and using it as a biological weapon. When the virus was combined with Leech DNA, the T-Virus was created. This tinkering with viruses and DNA is analogous to Nanotechnology because viruses are smaller than 100 nanometers. Although this scenario has not been reproduced in reality, it could be hypothetically possible with all of the new advances in the field of nanotechnology. Combining viruses to create new strains is possible due to the mutating capabilities of viruses. The Resident Evil series is a horrifying scenario due to the hypothetical possibility of it happening, a true example of nanotechnology gone wrong.

Nanotechnology is a very interesting idea and can be used for many useful things such as killing cancer or making structures. However without supervision, nanotechnology could also be used to make harmful things such as viruses or machines

This is a trailer for the Resident Evil: Degeneration movie. This movie is interesting due to the realistic situation where the virus starts at an airport which is promptly quarantined. http://www.youtube.com/watch?v=pjuN0xUJssg

This is a funny PSA about the T-Virus http://www.youtube.com/watch?v=biUF1ZlGlY4

Week 9: Nanotechnology - by Adam Parker

Monday, March 9th, 2009

Since it’s the last week of blog posts I’m just going to post a bunch of links to things that I think are cool and have to do with nanotechnology. Up first is the Nokia Morph concept phone. Using nanotechnology at the core of the Morph makes it extremely versatile. Users can switch between flexible and solid modes allowing users to bend it into a watch and lock it onto their wrist. The device can become transparent, change colors, and  be manipulated by its touchscreen. If this isn’t cool enough, the nanoparticles can be designed to be superhydrophobic making the entire phone weather and dirt resistant.

Designed for oil spills, these recyclable nanomesh paper towels designed by MIT students can absorb up to 20 times their original weight. The only catch it that they do not absorb water at all, meaning you won’t be buying these for your kitchen anytime soon. The good news is that these will go a long way in the effort to prevent and safely deal with oil spills.

An assistant professor at Stanford has harnessed the power of nanotechnology for the development of super long-lasting lithium-ion batteries. Meaning we could see laptops with 20 hour batteries and ipods that can last a week sometime in the near future.

Nanotechnology batteries

The recently created NanoNuno umbrella has the amazing ability to become completely dry after just one shake. Covered with nanotech particles, the material doesn’t absorb any of the water it comes into contact with. Get yours for only $94. Available Now.

One of the most interesting nanotech related inventions comes to us in the form of bullets. Scientists have figured out a way to attach tiny nano tags to gun cartridges. Once fired, the nano tags stay attached to the bullet allowing crime scene investigators to easily match bullets to their respective guns and suspects.

It’s been a fun and interesting quarter. Thanks for reading. Goodbye.

Week9_Nanotechnology by Manuel Aleman

Monday, March 9th, 2009

            Nanotechnology has been a big subject recently.  There has been much debate on the implications of nanotechnology.  Nanotech can help create many new materials and devices for many different areas, such as electronics, energy production, and medicine.  However, nanotech raises many of the same issues as with any new technology, which include concerns about the environmental impact of nanomaterials, their effects on global economies, and their toxicity.  One area that nanotechnology has helped is construction and architecture.  There have been many new innovations with concrete that have been made because of nanotech.  Concrete has been innovated to bend like metal and even to be five times as strong as regular concrete without any reinforcing steel bars.  There have even been innovations which created concrete which doesn’t need a vibration machine to remove the air bubbles inside, which can save lots of time during construction. Furthermore, there are also translucent concrete or concrete incorporating transparent elements, allowing people to build floors that are lit from below.

            Cement industries use to produce 7% of the human production of carbon dioxide, which brought about efforts for greener materials.  One huge innovation with concrete, because of nanotech, has been self-cleaning concrete.  It was found that if you add titanium dioxide to cement, you obtain a self-cleaning concrete that not only remains the same color for centuries, but can even clean the air by breaking down dangerous pollutants.  When titanium dioxide absorbs UV light, it becomes highly reactive and it starts to break down pollutants that come into contact with the concrete. Concrete can be brittle and can even break under a heavy load, but a new concrete called Ductal addresses these problems.  Ductal is five times stronger and can bend.  Since it is able to bend, it will show signs of cracking before it falls, so you will be able to see that there is a problem in advance.  Ductal is made by adding small fibers, made of steel or polymer, throughout the concrete.  These fibers reinforce the concrete.  During production of concrete, the concrete is consolidated and needs to be kept damp so that the concrete achieves a high early strength.  When finishing production the concrete has to be vibrated to remove air bubbles.  A new cast-in-place concrete named Agilia improves the productivity of concrete.  Agilia is a self-consolidating concrete that requires no vibration.  Agilia is highly fluid-like and spreads into place under its own weight.  Agilia contains a mix of superplasticizers which keep the concrete fluid and cuts down on the water needed.  It also achieves good consolidation without internal or external vibration and it does not show defects that are caused by segregation or bleeding of the concrete.  This reduces the time and costs of production.

Week 9_Nanotech by Dalton Abbott

Monday, March 9th, 2009

Before this week’s lectures, I was very unfamiliar with the field of nanotechnology and its scientific impact, but Professor Vesna’s lecture and the guest speaker’s presentation provided certain valuable insight into the importance of further developing research regarding nanotechnology. Nanotechnology concerns controlling matter at an atomic or molecular scale, a very small size at which particles are invisible to the human eye. I feel that because of this fact, people often underestimate the importance of nanotechnological engineering. Most do not realize the profound impact of the molecular makeup of virtually any matter whatsoever, resulting also in a lack of understanding of the potential scientific breakthroughs and discoveries made in the field of nanotechnology. A few days ago, I happened to stumble upon a CNN article that directly supports my previously stated argument of the importance of nanotechnology in this rapidly advancing technological world.

The article, which can be found here, discusses how developments made through nanotechnology resulted in increased solar panel efficiency. A coating, made from silicon dioxide and titanium dioxide nanorods, is applied on top of the solar panels, which causes the amount of usable absorbed light to jump from about 67% to over 96%. The coating allows sunlight to be captured from all angles rather than only from specific ones, and scientists and developers are expecting to transform the solar energy market within the next few years. In this case, a seemingly simple coating allows for an almost fifty percent boost in solar panel efficiency for any who care to purchase it when it becomes available for mass distribution. With the country in a seemingly insurmountable energy crisis, solar technology is going to be increasingly relied upon in the future, as it is a renewable resource and is also cost-effective is one is willing wait to see a return on one’s investment.

I found another insighful, yet perhaps more ambitious, article on CNN as well, which can be accessed here. This article focuses on scientist Naomi Halas’s vision of using nanotechnology to cure cancer. During the interview, she outlines the process by which cancer would be eliminated, which involves the creation of “nanoshells” that invade a cancerous area and use light reflection to “gently” destroy a cell, creating a non-invasive or rigorous but still potentially life-saving form of treatment. Though this approach is still in its developmental stages and is most likely years away from implementation on any large scale whatsoever, it provides another form of evidence for the infinite possibilities made available by nanotechnology. In being able to access and alter matter in its developmental stages, scientists are able to work on a completely new level of innovative freedom. They are able to approach seemingly unsolvable problems in a completely new light in the sense that nanotechnology opens doors never before thought possible. As long as the field of nanotechnology continues to be adequately and appropriately funded, there is no reason to believe that a multitude of new discoveries and potential functions of the incredibly diverse, far-reaching discipline won’t continue to be accessed or developed at a rapid pace. Upon reflecting on the past week’s teachings, I now view the future of science in a new light, as nanotechnology offers an endless possibility hope and opportunity for scientific progress.

Extra Credit_Sound+Science Symposium by Manuel Aleman

Monday, March 9th, 2009

            I attended two of the presentations for the sound and science symposium. I attended the Gabor’s Sonic Model presentation by Curtis Roads and the Illusions in Music and Speech by Diana Deutsch.  Curtis Roads is a composer of electronic and electroacoustic music.  He teaches and pursues research in the area of music and technology.  He was Editor and Associate Editor of Computer Music Journal, and he cofounded the International Computer Music Association in 1979.  He was also a researcher in computer music at MIT, and he also has had experience working in the computer industry. He was invited to teach electronic music composition at Harvard University, and sound synthesis techniques at the University of Naples. He has also been appointed Director of Pedagogy at Les Ateliers UPIC and Lecturer in the Music Department of the University of Paris VIII.  Lately, he has been researching a new method of sound analysis that is the analytical counterpart of granular synthesis called dictionary-based methods.  Electronic music is music that uses electronic musical instruments and electronic music technology in its production.  Roads showed in his presentations many things that deal with electronic and electroacoustic music, as well as things involved with his research and analysis of sounds.  One work he showed us was how he recorded pulses and could speed up or slow down the pulses in order to make a melody.  One of the most memorable parts of his presentation was a project where he recorded a Ferrari accelerating and decelerating.  He then edited the recording so that you could only hear the engine.  He played the edited version for us and while the track was playing increased the speed and slowed it down in order to create different melodies.

            The second presentation I attended was Illusions in Music and Speech by Diana Deutsch.  Deutsch conducts research on perception and memory for sounds, and music. She has discovered a number of musical illusions and paradoxes, which include the scale illusion, the glissando illusion, the octave illusion, the cambiata illusion, the triton paradox, and others. She also explores ways in which we hold musical information in memory, and in which we relate speech and the sounds of music to each other. Much of her current research focuses on absolute pitch.  In her presentation she went over many of the illusions she has researched and some of the findings that went along with it.  One project she presented was the octave illusion, which she herself discovered.  The octave illusion is an illusion produced when simultaneously playing two sequences of two notes that are spaced an octave apart.  Most people hear a single tone that switches between their left and right ears, while simultaneously the pitch switches back and forth between high and low.  She said the reason for this was because the tones are sine waves of constant amplitude, and switch between high and low four times a second, with no amplitude drops and that most people do not hear this pattern correctly, which is why the illusion rises.  The most memorable project presented was the tritone paradox.  The tritone paradox is another illusion where a pair of “shepard tones”, which are seperated by a half octave, was played.  The paradox is that some people hear the notes ascending and others descending.  Deutsch ended the discussion of the paradox by discussing how different populations tend to hear the notes the same way.

Week 9_Nanotechnology, the iPod, and GMR by Sarah Lechner

Monday, March 9th, 2009

 During lecture, Professor Vesna mentioned a poll measuring the percentage of iPod Nano owners who had heard of nanotechnology versus the percentage of iPod Nano owners who did not know what nanotechnology was.  The percentages that resulted were quite shocking.  A significantly larger amount of iPod Nano owners had never even heard of nanotechnology!  This seems paradoxical, since a portion of the word nanotechnology is in the name of the product.  Personally, I am an iPod Nano owner and have heard of nanotechnology, but I was not very clear on what roll nanotechnology plays in the iPod Nano.  I decided to look into the relations between nanotechnology and the iPod and was fascinated by what I found.

On October 9, 2007, the two men who discovered the technology that makes the iPod possible were rewarded with the Nobel Prize for Physics.  These two men are Albert Fert and Peter Grunberg.  Back in 1988, Fert and Grunberg independently discovered an effect known as giant magnetoresistance (GMR).  So how is this process with “giant” in its name related to “nano”technology?  In a GMR system, very small changes in magnetic resistance result in much larger changes in electrical resistance.  This allows information to be stored in an extremely small area that is still readable.  Therefore, the giant magnetoresistance effect allows us to store huge amounts of information in a magnetically charged microscopic area that can be read by translating the information into electric current.  Clearly, the giant magnetoresistance effect plays an important role in both the storage and retrieval of information.

The products of the discovery of GMR are vast.  Since the discovery of GMR, computers have rapidly improved, mp3 players have been developed and miniaturized, and nanotechnology has become a very applicable field of research.  For example, look at the line of iPods that Apple has produced in the last 10 years.  The first iPods were bulky and could store a relatively limited amount of songs.  Here is the promotional video released with the first iPod: First iPod

After the the first generation of iPods, Apple began introducing a whole new world of memory storage.  Within the span of a few short years, memory increased from 30 GB to 120 GB.  Apple then had the freedom to introduce video, photos, and games to these remarkable devices.  Apple just recently released their newest gadget, the iPod shuffle (3rd generation).  This device holds up to 1,000 songs, has the ability to speak the name of the song, and is less than two inches tall.  

So from 2001, when the first iPod was released, to 2009–a span of eight short years–the iPod has shrunk from 4 in. tall and 2.5 in. thick, weighing 6.5 oz. (with only 5 GB of memory) to a tiny 1.8 inches tall and .7 in. thick, weighing .38 oz.  See for yourself:

 

Original iPod

New iPod Shuffle

New iPod Shuffle

 Although nanotechnology is now being applied to a multitude of projects (many of them more beneficial or important than that of an mp3 player), I think that the time line of Apple products is a nice visual for the quick progression of nanotechnology over the last decade.  Once a science of the future, nanotechnology is now a very real, exciting topic in science today.

Blog #9 on Nanotechnology by Sara Captain

Monday, March 9th, 2009

The article about in “Technoetic Arts” by Victoria Vesna and Jim Gimzewski titled “The Nanomeme Syndrome: Blurring of fact & fiction in the construction of a new science” contains many interesting ideas that pervade above and beyond the subject at hand, nanotechnology. For instance, there is the element of perception. In the article, they write that it’s like the “doors of perception” have been opened to society by the invention of the STM in the early 1980’s. I couldn’t help but recognize this metaphor as being famous; William Blake coined it in 1793 in “The Marriage of Heaven and Hell,” then Aldous Huxley wrote about “The Doors of Perception” in his writing about drugs, and then the metaphor was popularized by Jim Morrison, who named his rock band The Doors after it. Blake uses the phrase to explain why Hell uses etchings for printing: “If the doors of perception were cleansed every thing would appear to man as it is, infinite. For man has closed himself up, till he sees all things through narrow chinks of his cavern.” It is interesting that Vesna and Gimzewski should reference the STM to the etchings for printing in Hell, whether intentionally or unintentionally, because there are in fact many differences between the two; while both are tools for precision, one engraves a person’s ideas, while one only observes or “feels” atoms and molecules. Thus, while the STM does “cleanse” doors of perception because it enables humans to observe objects as they truly are, it does not “open” doors of perception because the objects being perceived were always there. The STM helps clarify, correct, and guide a person’s perception of things, but it does not necessarily open doors to very new, foreign objects to be perceived. Therefore, I think understanding that the analogy made in the article finds its roots in a reference to Blake’s work helps give the phrase “doors of perception” in the article a fuller meaning.
Perception, nonetheless, seems to play a defining role in the article. Vesna and Gimzewski argue that Nanotech nessesitates cooperation between science, technology, and art. However, the only point at which I felt convinced of this while reading the article was when they came out and said that media arts similarly plays with manipulation of sensory perception in the same way that microscopes are able to magnify miniscule objects so that they are perceived as large by the human eye. I felt this was the only time during the article when the connection was made between the science of STMs and the art of media technology. The perceptions we have of objects can be habitually altered by technology, and this acknowledgement unites microscopes with movie cameras. However, for Vesna and Gimzewski to assert that, “…media artists, nano-scientists and humanists need to join forces together and envision such possibilities,” may be a bit over-warranted. Why should they? Why does this proposition call for a “need to join forces” as opposed to continuing with the disparities between them? Sure, they can and should share their advancements for the sake of general progress, but why should there in any way need to be a unification? This call for action seemed a little arbitrary to me, but perhaps I am underestimating the possibilities and end purpose of STMs and the like.

But Vesna and Gimzewski themselves state that “In science, commonly agreed human perceptions are constantly in question.” So, wouldn’t it be destructive to science to try to conglomerate pure science with other manipulations of perception? Isn’t the purpose of science in the first place to try to weed out irrationalities, misperceptions created by the imagination? While the purpose of most arts is the exact opposite, to celebrate the irrationalities, the perceptions (not “misperceptions) created by the imagination?

Week 9_ Nanotechnology By: Nicolina Greco

Monday, March 9th, 2009

Before I took this class, even as a science major, I had never heard the term nanotechnology, nor did I know what it is all about. After doing research and listening to our guest speaker during Thursday’s lecture, I now have a better understanding of Nanotechnology and how it is being discovered today. 

Nanotechnology is defined as the engineering of functional systems at a molecular scale. It is believed that by engineering tiny machines, we are projected to eventually have the ability to build things from “bottom up” inside personal nanofactories. A “personal nanofactory,” or “PN” as it is called, is a proposed new appliance that can be used at home that can combine individual molecules into useful shapes. Eventually, these nanofactories will build off each other, hence the bottom up theory. By using mechanochemistry, nanotechnology will be able to control matter matter from a nanometer scale. Mechanochemistry is the idea of using a vaccuum to push or pull a molecule the right way until you create the exact reaction you wanted. The following is an illustration of how mechanochemistry is predicted to work: 

While in the vacuum, a mechanical manipulator is used to add an atom to a surface. The atom is first bound to a molecule at the tip of the mechanical manipulator and is pointed to where you want it placed. By placing the atom close enough to the surface, the bond will transfer. What makes this chemical reactivity different from regular chemistry is that through mechanochemistry, the tool tip can be directly positioned by a computer so that this one reaction can be performed at a wide variety of sites on the surface, allowing for more variability in what can be created.

Significant names to remember concerning this revolutionary scientific breakthrough are K. Eric Drexler and Richard Feynman. In the 1980’s, Drexler was the first researcher who popularized the name “nanotechnology” when he proposed to the idea of building machines at the scale of molecules only a few nanometers wide, smaller than a cell. He proposed to create machines such as motors, robotica arms, and computers on this sub-atomic level, which is quite hard to imagine. As he devoted his life to his research, much criticism bashed the idea of nanotechnolgy, calling it a work of science fiction. However, as more and more research is being conducted, nanotechnology as a whole has become more accepted and supported. 

Much of Drexler’s inspiration came from the famous Nobel Prize winning physicist Richard Feynman. Feynman claimed that thnigs could be fabricated from the bottom up on an atomic level. The following quote is Feyman’s vision that helped me to undertand the perspective of nanotechnology a lot better:

I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. . . The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big. — Richard Feynman, Nobel Prize winner in physics

Although it is hard for us  to imagine, Feynman makes a solid arguemnt in that these tiny factories are very likely to be created within the next few decades. A man named Mike Roco of the U.S. National nanotechnology initiate descried the 4 generations of nanotechnology development, as seen below:

According to this chart, we are currently in the second stage of the proposed cutting edge research. In fact, it is awesome to realize that one of top facilities for this research is right here on campus at UCLA at the California NanoSystems Institute (CNSI). CNSI has recently partnered with NanoPacific Holdings Inc. to commercialize nanoparticle-based technology that could prolong the lives of cancer sufferers. The following link is an article that further explains this nanotechnology partnership research , and shows just how awesome, cool, and important our school is:

 <http://nanotechnologytoday.blogspot.com/2008/01/ucla-industry-partnership-to-develop.html>.

With all the cutting edge research and scientific findings in nanotechnology, I am now convinced that it will become the next revolutionary breakthrough in science in the years to come.

Week 9_Lithoparticles and Buckypaper by Christina Cheng

Sunday, March 8th, 2009

            In the world today, nanotechnology is becoming more and more prominent in both research and commercial use.  Here at UCLA, Professor Thomas Mason of the Department of Chemistry has taken a big step toward the field of nanotechnology in creating nano-sized particles called lithoparticles.  Although I am not familiar with the chemistry details of how lithoparticles are produced, it basically involves adding polymeric material to a liquid medium.  The fluorescent particles can then be manipulated to be of certain shapes, size, or even alphabets.  At the Mason Lab, researchers even succeeded in creating the 26 alphabets, and they were able to pick up and arrange these lithoparticle alphabets using laser tweezers.  Meanwhile, the importance of lithoparticles lies not only in its method of production, but also in the significance that lithoparticles are smaller than most cells.  The fact that scientists are now able to generate tiny particles that they can manipulate into a form that is desired demonstrates the power of being able to control many biological processes in the near future.  For example, it is possible that lithoparticles may one day be used to direct certain signaling procedures or to fit with certain enzymes.  In addition, due to the small size and fluorescent nature of the lithoparticles, it may also be possible to use them as markers that can be inserted into cells to allow researchers to follow and identify different cells.  Personally, I think it is amazing how the lithoparticles are produced with such detail in both size and form.  Not only are they uniform in size, but it is also obvious that they are of the same font.  The appearance of these lithoparticles is almost identical that of typed alphabets on the computer.  At the Mason Lab, one of the researchers even arranged the alphabets in an order that spells “UCLA,” as shown below:

 

Here is a link to more information about Mason’s research: http://www.sciencedaily.com/releases/2007/03/070319174619.htm

 

            Talking about nanotechnology, I will have to touch on my idea of using nanomaterial in the structure I proposed for my final project, which was The Environmental Sky Tower.  For most of the class lecture on nanotechnology, we learned about fullerenes and carbon nanotubes, so I thought about how carbon nanotubes could be incorporated into my project.  After doing some research, I discovered that there are “buckyballs”, as well as “buckypaper.” Both “buckyball” and “buckypaper” are composed of carbon nanotubes, but they are arranged in different ways in the two forms.  For my project, I proposed the addition of a film of buckypaper on the steel that is used to build the structure.  Although the name may give an impression that it is really a sheet of paper, buckypaper is actually produced from sheets of carbon nanotubes that are tightly stacked together.  While the material may be light, it is definitely a lot stronger than normal paper.  In fact, I was shocked when I read that buckypaper may be 500 times stronger than steel.  Recently, it was suggested that buckypaper may be used as one of the materials in automobiles, airplanes, and monitors in the future.  Moreover, since buckypaper conducts electricity and heat very efficiently, it may even be used in the production of computers that are highly effective in dissipating heat.  Currently, nanotechnology is already being used to produce nanolaminate metals that are stronger than regular metals.  My idea of applying a film of buckypaper is similar, except it will require a mass production of sheets of carbon nanotubes due to the large size of the structure.  Hopefully, the use of buckypaper and carbon nanotubes as building materials will become more prevalent in the near future, for that the strength of these materials will definitely allow us to construct stronger buildings that are less prone to damage and natural disasters.

week 9: nanotechnology

Sunday, March 8th, 2009

The lecture on Thursday, by Professor James Gimzewsk, allowed me to understand the importance of fusing art, science, and technology. The fusion of art, science and technology in today’s world can lead to the creation of many small objects for the improvement of the human health, new electronics and seeking for better energy production.

Many scientists have begun work in the creation of nanotechnology by controlling matter at the atomic and molecular level. This control has allowed for the innovating thinking and creation of a nano-particle that would improve the health of a patient with cancer. You may ask how an object smaller than a strand of hair can possibly improve the health of a patient, that is suffering from cancer? The answer is simple. As you may know the as the US technology is growing at a fast rate, its scientists have begun to work on a nano-particle that can diagnose cancer. These nano particles are more accurate and are much cheaper. Then they are also thinking in creating nano-shells can be linked to anti body, which would recognizes cancer cells and be taken in by the tumor. Then the particle would release some type of inferred light into the tumor cell getting rid of the tumor, without harming other human cells around it.

Not only is nano technology being used for the creation in the medical field but also many advance electronics and the production of energy, which might help us become energy independent. The power of nanotechnology will allow for the creation of faster computer chips, increasing the US technological power. In addition there are scientists that are seeking a better model of a solar panel to trap solar energy, in order to become energy independent. However there are very few supporter of the use and the development of nanotechnology, those who are against it fear that it would bring great harm to the environment and creating various toxins harmful to humans. This isn’t true for many scientist are seeking ways of creating nanotechnology that is helpful to US humans and also considering if the creation will arise to have any harmful affect on humans.

I believe that the technological advances of this century are fascinating however I believe that they should take into consideration if there it may lead to any harmful effects on humans and try to prevent it. For the idea of creating technology is for the improvement and well being of humans.

On Friday the 06, I attended two talks of the sound and science symposium.

The first one was title scaling the sonic terrain, this presentation was created to inform on the project of Andrea Fully, which deals with raising environmental awareness through sonification. Throughout her presentation she discussed how she utilized specific data of the environment, such as a hurricane and climate in NYC or even of Antarctica. The sounds she used were different some were high pitch some low and each signified a different part of the data. I found this quite interesting for I didn’t know that environmental awareness was also being displayed through sound. I was also amused of the sounds that nature creates, what I would like to do is take the sounds she created and listen to them while standing in the location she created them to see how the sounds relate with the environment.

The second presentation I attended was the one on insects, trees and climate by James P. crutchfield. Throughout his presentation he discussed how the tree beetles are being studied, as well as the tree they reside in. He stated that many scientists as well as he are taking ultra sound of the tree where the beetles are residing and the bugs themselves; however each creates a different sound which helps them distinguished in the ultrasound. The ultra sound of the tree can tell the state of infection of the tree. This ultra sound helps gather informing on the current state of the outbreak of the tree beetles due to climate change.
