Resizenowmap.jpg (715×514) TED: Ideas worth spreading. How to Forecast Weather. Ever wondered how to forecast the weather without actually using instruments? Check the Clouds: Clouds can tell us a lot about the weather. For example, they can tell us if it’s going to be warmer on a particular night by simply being there. That’s because they prevent heat radiation from escaping. They can also tell you whether there will be rain and whether there will be bad weather in general (when you see clouds moving in opposite directions of each other). Check the Humidity: If you’re one of those people whose hair gets all curly when it gets really humid out, you know exactly what this is about. Check the Animals: Birds only fly in the sky when they expect fair weather ahead.
Look at the Rainbow (but only in the west) and look for a Red Sky: If you see one in the west, it means a major storm front is coming. Check the Air: If it smells like a compost heap, expect some rain soon. Check the Moon: Seen any red moons lately? Check the Wind: Lectures. Quantrev. NASA Science.

Watch the Program (full-screen) 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. Biology Project - site map.
Communicating at an unknown rate. 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. Despite its fragility in certain regards and its incredible lack of density, aerogel has amazing thermal, acoustical and electrical insulation properties as illustrated by the images here. A single one-pound block can also support half a ton of weight. NASA continues to find new space-based applications for this incredible material. An aerogel window one inch thick has the effective insulative capacity of a ten-inch thick glass window system. 100 Best (Free) Science Documentaries Online.
