The Elegant Universe: Pt 1

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.

Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary.

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Solar System Scope Breakthrough Nanotechnology Will Bring 100 Terabyte 3.5-inch Digital Data Storage Disks Have you ever dream of 100 terabyte of data per 3.5-inch disk? New patented innovation nanotechnology from Michael E. Thomas, president of Colossal Storage Corporation, makes it real. 100,000 Stars Chapter 1: Magnetism - Magnetorheological fluids, homemade ferrofluid Magnets and Magnetism We have all played with magnets. A pair of magnets by itself makes a wonderful toy. Today's magnets are even better than the best ones I remember playing with as a child. At toy stores and Radio Shack you can get flexible magnetic strips of plastic that can be cut into shapes with scissors. You can also get cheap and brittle ceramic magnets, stronger Alnico magnets, and even the new super strong rare-earth magnets.

NASA - Home A Science Odyssey: You Try It: Atom Builder How small can we go? The stuff you scrape off burnt toast is made primarily of atoms of carbon. But what makes up a carbon atom -- or any other atom? The first subatomic particle to be identified was the electron, in 1898. Effects of Nuclear Weapons When a nuclear weapon explodes in the air, the surrounding air is subjected to great heat, followed by relatively rapid cooling. These conditions are ideal for the production of tremendous amounts of nitric oxides. These oxides are carried into the upper atmosphere, where they reduce the concentration of protective ozone. Ozone is necessary to block harmful ultraviolet radiation from reaching the Earth's surface. Oxides of nitrogen form a catalytic cycle to reduce the protective ozone layer.

Spectra of Gas Discharges Below are images of the spectra of the lines of each element which would be observed as emission lines in an electrical gas discharge. The images are screen shots of an applet - originally written by John Talbot - which reads in a file with wavelengths and intensities and makes a colourful representation of the spectrum.
