The Elegant Universe: Series ...
The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. S. BRIAN GREENE:The atmosphere was electric. S. S.

Albert-László Barabási Albert-László Barabási Robert Gray Doge Professor of Network Science Director, Center for Complex Network Research PhD Boston University, 1994 (617)373-7774a.barabasi@neu.edu Research Summary: Just about every field of research is confronted with networks. Metabolic and genetic networks describe how proteins, substrates and genes interact in a cell; social networks quantify the interactions between people in the society; the Internet is a complex web of computers; ecological systems are best described as a web of species. June 2010 In Fractal Finance, Part I we saw that fractals can be useful in describing complex, seemingly chaotic patterns in nature. We also saw how Wall Street took advantage of the same advances in information technology that made the study of fractals possible starting in the 1980s, to come up with computer-driven black-box trading schemes. For example, index arbitrage strategies were widely blamed for the Black Monday crash of October 1987. Wall Street is always on the look-out for new "angles", opportunities to better skin a cat in a place already full of very sharp razors.

Frequency Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s), meaning the number of seconds per cycle. T and f are reciprocals. In some fields, especially where frequency-domain analysis is used, the concept of frequency is applied only to sinusoidal phenomena, since in linear systems more complex periodic and nonperiodic phonomena are most easily analyzed in terms of sums of sinusoids of different frequencies. Definitions and units[edit] Sinusoidal waves of various frequencies; the bottom waves have higher frequencies than those above. Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. It's even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts.

NOVA Jessica Cail "If there's ever a zombie apocalypse, everyone's gonna want me on their team." From SLOSE | Apr 8, 2016 Revealing the Universe’s Mysterious Dark Age Astrophysicists are pushing cosmological theories to their limits to shed light on the universe’s mysterious dark age. Marvin Minsky's Home Page MIT Media Lab and MIT AI Lab Professor of Media Arts and Sciences, MIT Professor of E.E.C.S., M.I.Tminsky at media.mit.edu Abstracts Bibliography Biography People Marvin Minsky has made many contributions to AI, cognitive psychology, mathematics, computational linguistics, robotics, and optics. In recent years he has worked chiefly on imparting to machines the human capacity for commonsense reasoning. His conception of human intellectual structure and function is presented in two books: The Emotion Machine and The Society of Mind (which is also the title of the course he teaches at MIT).

Interesting numbers - Imaginary and complex numbers Interesting numbers --- zero --- one --- complex --- root 2 --- golden ratio --- e --- pi --- googol --- infinity What is i? The square of a number is itself multiplied by itself. It's written with a little 2 above and after the number. So 32 = 9 means three squared is nine. The opposite of a square is a square root, which looks a little like a tick.

Hertz "Megahertz", "MHz", "Gigahertz" and "GHz" redirect here. Top to bottom: Lights flashing at frequenciesf = 0.5 Hz (hertz), 1.0 Hz and 2.0 Hz, i.e. at 0.5, 1.0 and 2.0 flashes per second, respectively. The time between each flash – the period T – is given by 1⁄f (the reciprocal of f‍), i.e. 2, 1 and 0.5 seconds, respectively.

The Scale of the Universe Light travels at 300,000 kilometres per second (186,000 miles per second). In one second, a beam of light can travel SEVEN TIMES around the Earth. This table shows a number of distances to various objects expressed in terms of how long a beam of light takes to travel that distance. Time scales longer than the age of the Universe are possible because of the expansion of the Universe. The scale of the Universe and our place in it are well summarised in Monty Python's Galaxy Song. © 1997, 2013 KryssTal Aerogel: See-Through, Strong as Steel & Ligher than Air « Dornob Despite its incredibly low density, aerogel is one of the most powerful materials on the planet. It can support thousands of times its own weight, block out intense heat, cold and sound – yet it is 1,000 times less dense than glass, nearly as transparent and is composed of %99.8 air. The lowest-density silica-based aerogels are even lighter than air.

3.5m Observatory - One Degree Imager The ODI project is partially funded through the NSF Telescope System Instrumentation Program (TSIP). The One Degree Imager The One Degree Imager (ODI) is the flagship of the WIYN Consortium's new instrument initiatives. The combination of its large size and ability for electronic image stabilization make ODI a unique and very competitive instrument. ODI is sensitive to visible light and features a one thousand mega-pixel camera, an impressive number compared to the average digital camera at eight mega-pixels. The camera will cover a one-square-degree field of view which will allow ODI to capture vast areas of sky, greater than four times the area of the full moon, in a single image.

Unveiling the Mandelbrot set September 2006 Back in the 1970s and 1980s, mathematicians working in an area called dynamical systems made use of the ever-advancing computing power to draw computer images of the objects they were working on. What they saw blew their minds: fractal-like structures whose beauty and complexity is only rivalled by Nature itself. Oscillation Oscillation is the repetitive variation in time of some measure about a central value (often a point of equilibrium) or between two or more different states. The term 'vibration' is precisely used to describe mechanical oscillation but used as a synonym of 'oscillation' too. Familiar examples include a swinging pendulum and alternating current power.
