Impossible: Physics beyond the Edge

Absolute Zero (1x7)

Date de diffusion: Jan 01, 2010

Learn how absolute zero (0 K or -273.15 degrees Celsius) is unattainable due to the third law of thermodynamics. Nonetheless, remarkable things happen on the way toward this impossible goal. For example, electrical resistance and viscosity drop to zero in certain substances, and weird quantum mechanical effects occur.
