How To Imagine The Tenth Dimension Video. Nature by Numbers Movie. Do People Always See the Same Things When They Look At Colors? Update: It looks like the video was taken down by the uploader. Sorry guys. Color is simply how our brains respond to different wavelengths of light, and wavelengths outside the spectrum of visible light are invisible and colorless to us simply because our eyes can’t detect them. Since colors are created in our brains, what if we all see colors differently from one another? BBC created a fascinating program called “Do You See What I See?” That explores this question, and the findings are pretty startling. In the English language (and most languages), there are distinct words for “green” and “blue. However, when scientists visited a tribe in northern Namibia that has a completely different way of grouping and naming colors, they found that the exact opposite was true — the tribe members picked out the slightly different green square easily, while struggling to see the blue one.

Do you get frustrated when a big group of people strolls down a narrow hallway spread out from wall to wall? If you're in a hurry, it can be almost impossible to get past them. This weird looking flooring is designed to end that problem, by subconsciously nudging people over so they walk on the right. The floor uses lenticular lenses like those cheezy postcards that change depending on your viewing angle, only in this case the tile sections shift from dark to light in a pattern that moves over towards the right.

This tricks your brain into following the direction the pattern appears to be moving, over towards the right wall. If this actually works, I would be in favor of paving all New York City sidewalks with this stuff. Via OhGizmo! MIT Creates New Energy Source. This is some pretty exciting news. It seems that researchers at the Massachusetts Institute of Technology (MIT), one of the most prestigious science and engineering schools in the United States, has created a new energy source -- and it's clean and renewable. The odd thing is that the only way you can see this energy source is with a very powerful microscope, because it is created by using nanotechnology. For a few years now, we have been hearing about the possibilities offered by the new field of nanotechnology. Now it looks like the first usable breakthrough has been accomplished.

MIT has devised a process to generate electricity using nanotechnology. The researchers built tiny wires out of carbon nanotubes. The nanotechnology batteries will have a couple of other advantages over current batteries. Second, these batteries are non-toxic since they are made of carbon. Computers, cell phones and other electronic devices will be the first to benefit from the nanotechnology batteries. Microrobot swims through eyes to deliver drugs | Crave. Is that a speck in your eye? Or just a microrobot helping preserve your vision?

Researchers are working on tiny machines that can be directed through eyes to help treat conditions like macular degeneration, which can impair vision. Scientists at the Swiss-based Institute of Robotics and Intelligent Systems (IRIS) led by Bradley Nelson are developing tiny, electromagnetically controlled microrobots that can move to a target location in the eye and remain there for months, releasing drugs. The therapy is seen as an alternative to multiple eye injections to treat macular degeneration, which can lead to legal blindness. In the New Scientist vid below, the robot is seen moving in an eye taken from a dead pig. The microbots can also position a biodegradable drug capsule before they are removed with a magnetic needle. Nelson, whose group is part of the Swiss Federal Institute of Technology Zurich (ETH), said commercialization of the technology is being explored. The Sacred Geometry Of Music.

The Sacred Geometry Of Music by Andrew Lorimer Music uses the laws of vibration to manifest aurally what exists at the center of everything. Into our reality springs a non-visual harmonic law that is universal. The notes and intervals of music speak directly to the chakra centers and causes them to vibrate in harmony to the vibration of a string or vocal chords, speakers moving through the air, or the sound of someone’s lips making a farting noise through a metal tube. Music uses the laws of physics and mathematics to bring out an emotional response in the listener. The music of the Western world uses a mathematical system based on Twelve. All the songs you have ever known and sang along to in your life use the same simple laws based on the number twelve. Clock Harmonisphere The mathematics of the harmonisphere are amazing.

When we measure the same chords on the harmonisphere, the seven chords have the same mirrored combinations as the piano: Langton's Ant. A 4-state two-dimensional Turing machine invented in the 1980s. The ant starts out on a grid containing black and white cells, and then follows the following set of rules. 1. If the ant is on a black square, it turns right and moves forward one unit. 2.

If the ant is on a white square, it turns left 3. When the ant is started on an empty grid, it eventually builds a "highway" that is a series of 104 steps that repeat indefinitely, each time displacing the ant two pixels vertically and horizontally. (right figure) steps. Thinking Unconventionally. A Letter from a College Professor Some time ago I received a call from a colleague, who asked if I would be the referee on the grading of an examination question. He was about to give a student a zero for his answer to a physics question, while the student claimed he should receive a perfect score and would if the system were not set up against the student. The instructor and the student agreed to an impartial arbiter, and I was selected. I went to my colleague's office and read the examination question: "Show how it is possible to determine the height of a tall building with the aid of a barometer.

" The student had answered: "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. I pointed out that the student really had a strong case for full credit since he had really answered the question completely and correctly. At this point, I asked my colleague if he would give up.
