If the world is a chaotic flux of matter and energy, a seething mass of atoms everywhere, then why are there recognizable things at all?:
The most striking feature of many complex systems is their non-random nature. The universe is populated by distinct classes of recognizable things: galaxies, stars, crystals, bacteria, people. Given the limitless variety of ways in which matter and energy can arrange themselves, almost all of which would be 'random,' the fact that the physical world is a coherent collection of mutually tolerant, quasi-stable entities is surely a key scientific fact in need of explanation.
