Absolute zero is a situation that is impossible to achieve in reality. At that temperature the laws of classical physics break down. Even nearly above it, they start to misbehave enourmously.
That's really just to say that nature is less straightfoward than we think. There are a few situations where zero K might be beenficial. Example, electricity distribution could be revolutionised. Transmit it through zero resistance conductors without having to ramp up the PD to 425,000 volts or more. And through hair thin wires.
Problem, how do you keep 'em that cold? |
