As temperature increases starting from absolutezero they first decrease steeply in resistance as the carriers leave the donors or acceptors.

Then in 1951, in the first nuclear cooling experiment, he produced the lowest temperature ever achieved until then at only ten millionths of a degree above absolutezero.

Layzer argued that, rather than in an initial high entropy state, the primordial universe was in a very low entropy state near absolutezero.

The common organisms of choice to study cryobiosis are tardigrades, which are known to survive freezing to near absolutezero. We repeat the process until the model temperature reaches the value of absolutezero. For example, my theory would never permit causing pain to others in order to reduce the pain of maximum sufferers to absolutezero. Gas-phase reactions at low temperatures : towards absolutezero. The measure of the disorder is the residual entropy, which does not vanish even at absolutezero. The values are chosen so that the dynamics of vortex nucleation can be followed easily as the temperature approaches to absolutezero. This condition implies that at the critical temperature the magnitude of the initial order parameter does not exceed its value at the superconducting state at temperature absolutezero. In addition to tape noise (caused by random magnetic particles), circuits themselves inevitably produce noise due to electron movement (theoretically reduced as one approaches absolutezero of temperature!). I do not subscribe to the view that we must reduce it to an absolutezero. From the Hansard archive Example from the Hansard archive.
