When you squeeze some crystals, you distort their lattice of atoms just enough to separate a pair of charged particles and that in turn gives rise to a voltage. Such materials are called piezoelectric…

This post was originally published on October 6, 2012. I recently rediscovered it and decided to republish it with a few updates. Geometric symmetry in nature is often a sign of unperturbedness, as i…

Symmetry in nature is a sign of unperturbedness. It means nothing has interfered with a natural process, and that its effects at each step are simply scaled-up or scaled-down versions of each other. F…
