Loschmidt’s paradox

Loschmidt’s paradox, also known as the reversibility paradox, is the objection that it should not be possible to deduce an irreversible process from time-symmetric dynamics.

This puts the time reversal symmetry of (almost) all known low-level fundamental physical processes at odds with any attempt to infer from them the second law of thermodynamics which describes the behavior of macroscopic systems.

Both of these are well-accepted principles in physics, with sound observational and theoretical support, yet they seem to be in conflict; hence the paradox.

The most powerful illusion

Posted on by

One of the most powerful illusions of the human experience is the illusion that we’re seeing objective reality through our own perceptions. We can only see what we see.

— Christopher Nolan 

We simply assume that the way we see things is the way they really are or the way they should be. And our attitudes and behaviors grow out of these assumptions.

— Stephen R. Covey
