The winter games in Vancouver provide a chance for the United States' four-man bobsled team to win its first gold medal in more than 60 years. And with the help of Paul Doherty, senior scientist at the Exploratorium in San Francisco, Deborah King, associate professor in the Department of Exercise and Sports Sciences at Ithaca College, physicist George Tuthill of Plymouth State University, and bobsled designer Bob Cuneo, the team explains how they hope to accomplish this feat.

In February, Olympic skiers such as Julia Mancuso, Ted Ligety, Marco Sullivan and Scott Macartney will race down Vancouver's Whistler Mountain at speeds of up to 90 miles an hour. Paul Doherty, senior scientist at the Exploratorium in San Francisco, and Sam Colbeck, a retired scientist from the U.S. Army Cold Regions lab, explain the physics of this downhill thrill ride.

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt looks at the science of projectile motion and parabolas with the help of former NFL punter Craig Hentrich. NSF-funded scientists Professor Jim Gates from the University of Maryland, Professor John Ziegert of Clemson University, and Professor Rhonda Hughes from Bryn Mawr College, explain the...

It is a brief explanation about a relativistic space propulsion system which uses a lattice/matrix of Phase Displacement Space Drives, producing crisscrossing pattern of Phased Standing Waves, to generate a sequence of spinning waves for causing a FTL moving force, in order to warp spacetime, enabling fast interstellar travel in an energy-efficient way.

Science experiment, kids experiment with gravity while creating a pop bottle racer.

On the four fundamental forces of physics.

Our understanding of fundamental concepts like force, definition of mass and the inverse square law of gravity appears to be flawed. Our entire underdstanding of science is dependent on these very basic concepts. This three part series explores the validity of these concepts.
