Pendulum Waves

Watch this bead chain loop defy gravity and bend physics Science is unendingly cool because it can consistently confound the expectations of researcher and layman alike. Case in point, what do you figure would happen if you had a bead chain coiled up in a small container, then pulled one end out? You probably didn’t guess that it would leap up and uncoil like a tiny metallic snake, but that’s what happens. This demonstration is sometimes called Newton’s Beads.

History of nuclear weapons A nuclear fireball lights up the night in the United States nuclear test Upshot-Knothole Badger on April 18, 1953. Nuclear weapons possess enormous destructive power derived from nuclear fission or combined fission and fusion reactions. Starting with scientific breakthroughs made during the 1930s, the United States, the United Kingdom and Canada collaborated during World War II in what was called the Manhattan Project to counter the suspected Nazi German atomic bomb project.

But this is getting to be old hat for Fadnes, who last year won an international competition for wingsuit flying, earning him the sobriquet of the world's fastest flying human. Inspired to try?

Wave energy securing airports - Science (9) - ABC Splash - Overview Electromagnetic radiation is energy that travels in waves. Some examples include gamma rays, X-rays, microwaves and radio waves. Watch this clip to learn more about the properties of energy waves, such as wavelengths, and how electromagnetic radiation is being used in airport security to see through people's clothes but not their bodies. How will this help detect hidden weapons? Duration: 2 mins 29 secs Source : BBC Learning area: Science Secondary: Year 9

Students use giant balls to build omnidirectional motorcycle Riding this bike takes balls. Gigantic balls. Quite possibly the largest pair of balls you've ever seen in one place. Round wheels are out and spherical wheels are in with this project from students at San Jose State University, the end result of which will be a rideable electric motorcycle that uses balls instead of wheels.
