A very interesting animation of Faraday´s Magnetic Induction and Lenz´s Laws. A circular metallic ring is located in a region with an uniform external magnetic field. First, the ring is located in a plane perpendicular to the external field lines and the intensity of the field is increased, so the induced current on the ring and its corresponding field lines are shown. Then the ring is rotated and the corresponding induced currenta and field lines are presented.

On Wednesday, February 1 Dr. Steven Jones gave the following presentation on 9/11 and the physics of falling bodies and how it was physically impossible for these structures to have collapsed based on the conclusion that our government has given us. This video could possibly be the most conclusive work yet in disproving the 9/11 myth. Utah Valley State College

Many mechanical examples of Newton's laws of motion and the nature of our 'clockwork' universe are be demonstrated. These laws have enabled us to venture out into space and explore other worlds. The Voyager Mission to the outer planets are examined, and the slingshot effect, which enabled the Voyager spacecraft to reach their destinations in a fraction of the time taken by a direct route, will be explained and demonstrated. Finally, how likely are we to reach our nearest star in this millennium?
