entropy

Claude Shannon founded information theory in 1948, proved Boolean algebra runs circuits in 1937, built a maze-solving mouse, and juggled on a unicycle through Bell Labs hallways.

Ludwig Boltzmann built statistical mechanics, derived S=k log W, and defended atomic theory for decades against fierce opposition. His biography, science, and tragic end.

The four laws of thermodynamics, what entropy really means, heat engines, black holes, the arrow of time, and why life is a local entropy reversal.

Four laws govern how energy moves, transforms, and degrades, from the steam engine to every living cell. Thermodynamics explains why engines have limits and why time has a direction.

Stars will fade, black holes will evaporate, and entropy will win. Here is what physics says a very advanced civilization could do to stretch its lifetime, and where each strategy runs out.

The universe began 13.8 billion years ago and will end — eventually. But how? Heat death, the Big Rip, the Big Crunch, and vacuum decay are all on the table. Here's what physics actually predicts for the final fate of everything.

Entropy is the reason ice melts, eggs don't unscramble, and the universe is heading toward a quiet, cold end. Here's what entropy actually is — and why it's the most powerful idea in physics.
