Focus: Electron Spin Influences Nanotube Motion
The spin of an electron often occupies a reality all its own, with little bearing on the electron’s overall motion or the motion of nearby atoms.

Speed of light
From CreationWiki, the encyclopedia of creation science
The speed of light in vacuum is held to be constant at 299,792,458 m/s (186,282.397 miles per second). Designated by the symbol "c" (for "constant"), it is a fundamental quantity of the universe.
