Explanation of gyro precession: http://bit.ly/U4e8HQ More: http://bit.ly/GyroMORE Less Than: http://bit.ly/GyroLESS Equal To: http://bit.ly/GyroEQUAL Huge thanks to A/Prof Emeritus Rod Cross, Helen Georgiou for filming, Alex Yeung, and Chris Stewart, the University of Sydney Mechanical Engineering shop, Duncan and co. Ralph and the School of Physics. In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt like. Music By Kevin MacLeod www.Incompetech.com "Tempting Secrets"
Using a bucket with stretchy fabric stretched over it, allow visitors to experiment with marbles and weights to discover some basics about gravity and orbits. View more details about this activity here: http://1.usa.gov/1JxnkMv
This clip is taken from the NOVA PBS series "THE ELEGANT UNIVERSE' and is used under the provisions of the Digital Millineum Copyright Act of 1998 (Title IV). Brian Greene guides us through Newton's discovery of gravity to the explanation of it, through Einsteins Theory of Relativity. Brian Greene is a theoretical physicist and one of the best-known string theorists. Since 1996 he has been a professor at Columbia University. The Elegant Universe was adapted for a three hour program in three parts for television broadcast in late 2003 on the PBS series NOVA. http://www.pbs.org/wgbh/nova/elegant/
At the MIT Media Lab, the Tangible Media Group believes the future of computing is tactile. Unveiled today, the inFORM is MIT's new scrying pool for imagining the interfaces of tomorrow. Almost like a table of living clay, the inFORM is a surface that three-dimensionally changes shape, allowing users to not only interact with digital content in meatspace, but even hold hands with a person hundreds of miles away. And that's only the beginning. Created by Daniel Leithinger and Sean Follmer and overseen by Professor Hiroshi Ishii, the technology behind the inFORM isn't that hard to understand. It's basically a fancy Pinscreen, one of those executive desk toys that allows you to create a rough 3-D model of an object by pressing it into a bed of flattened pins. With inFORM, each of those "pins" is connected to a motor controlled by a nearby laptop, which can not only move the pins to render digital content physically, but can also register real-life objects interacting with its surface thanks to the sensors of a hacked Microsoft Kinect.

7 OPTICAL ILLUSIONS THAT WILL PUT YOUR BRAIN TO WORK Do you like puzzles? Even in the pre-internet era, optical illusions were very popular. You know, pictures with a full-fledged landscape, a portrait or a simple still life, but if you look at them from a certain angle, it miraculously turns into something different. For example, the branches of trees take the shape of faces, the waves of a raging ocean turn into silhouettes, and sometimes it happens that the beautiful girl on a portrait gets old and becomes a disheveled old lady with a huge nose right in front of your eyes

Dan Burns explains his space-time warping demo at a PTSOS workshop at Los Gatos High School, on March 10, 2012. Thanks to Shannon Range from the Gravity Probe B program for creating the original demonstration which he shared with Dan in 2004.
