Ehrenfest paradox (Ehernfest, 1909)
The special relativistic "paradox" including a quickly rotating disc. As any radial segment of the disc is perpendicular to the direction of motion, there must be no length contraction of the radius; though, since the circumference of the disc is parallel to the direction of motion, it has to contract.
