...ased on the size of their molecules, a vortex tube spins gas at a high centrifugal force -- this causes gases to move at different speeds through the tube. "The vortex is sort of like a tornado in a tube.

...toring the data in a central data bank." As the CD spins inside a CD player, centrifugal force pushes liquid medical samples from the inner channels out to the edge, where it mixes with tiny pools of chemicals for testing. All types of analytical functions necessary for the test take place at that time. "W...Chemists spin materials to improve magnetic resonance data

...parts of the Sun spin faster than others." The Sun spins once on its axis every 27 days or so, on average, with the equatorial regions spinning faster than the polar regions of the visible surface. A few years ago, when helioseismology began to reveal the internal pattern of spin, big surprises emerged --...Scientists re-evaluating the meaning of 'desertification,' Duke ecologist says
