How did one philosopher's colossal mistake derail human science for 2,000 years? Learn about the fierce ancient debate over the nature of matter, from Empedocles and the early atomists like Democritus, to Aristotle's rejection of the atom. And, learn why it matters for general chemistry students and the MCAT.
