Will the Universe End in Heat Death? What Physi...

“Heat death” is the idea that the universe runs down until no energy differences are left to do work. It began with Kelvin’s 1852 dissipation paper. Modern cosmology refines it:...

A treasure vault where a heap of gold coins under a shaft of light has spilled into a disordered scatter across the floor

What Exactly Is Entropy? Boltzmann’s S = k log ...

Entropy is not really “disorder.” It is a count of how many microscopic arrangements look the same from outside. Here is Clausius’s version, Boltzmann’s formula, and why the count almost...

A giant hourglass of glowing golden sand on a cliff at dusk beside a shattered egg, dust blowing away on the wind

Why Does Time Only Go Forward? Entropy and the ...

The basic laws of motion work the same forwards and backwards, yet eggs never unscramble. The answer runs through entropy, probability and the state of the early universe, and part...
