Critical Hit

[dakyon]

Unlike classical physics, quantum physics reveals astonishing and fascinating new phenomena. For example, atomic particles still move about at absolute zero - a consequence of Heisenberg’s Uncertainty principle. These quantum fluctuations can result in transformations between different material states. If these phase transitions occur at absolute

I thought that absolute zero, in classical physics or otherwise, was merely a theoretical, asymptotic "temperature" that could be approached but never actually achieved. Even in classical physics, isn't it considered impossible to completely stop the motion of particles?

Forgive me, it's been a while since i studied either form of the subject.

It's impossible to hit absolute zero, but we've come *very* close (0.45 nK). And yes, theoretically, subatomic particles still move around at absolute zero, albeit not very much.

You are correct. Technically, absolute zero cannot be achieved. However, the the classical assumption is that were we able to reach such a temperature, particles would retain no energy, and thus no motion . . .the regression should be somewhat linear. The quantum fluctuations from the uncertainty principle actually contest that smooth linear regression.
