These things were proposed to contain outward-flowing layers called simulacra by a Roman thinker who described their downward motion being interrupted by random deflection. (10[1])Lucretius’ De rerum (10[1])natura claims free will is caused by the “swerve” of these things. (10[1])The so-called “laughing (-5[1])philosopher” is best known for his theory of these things, which Leucippus contrasted with the void existing between them. Democritus theorized that (10[1])the universe (10[1])is made of these things, (10[1])which are (10[1])named for the word for “uncuttable.” For 10 points, (10[1])Greek philosophy conceptualized what smallest units (10[1])of matter that today name structures containing protons and neutrons? ■END■
