These things were proposed to contain outward-flowing layers called simulacra by a Roman thinker who described their downward motion being interrupted (10[1])by random deflection. (10[3])Lucretius’ (10[1])De (10[1])rerum (10[1])natura (10[1]-5[1])claims free will is caused by the “swerve” (10[2])of these things. (10[5])The so-called “laughing (-5[1])philosopher” is best known for his theory of these (10[1])things, (10[3])which (10[1])Leucippus (10[1])contrasted with the void existing (10[1])between them. (10[2]-5[1])Democritus (10[4]-5[1])theorized (10[3])that (10[1])the universe (10[4])is (10[1])made (10[1])of (10[1])these (10[2])things, (10[9])which (-5[1])are (10[2])named for the word for “uncuttable.” (10[5])For (10[1])10 points, (10[4])Greek (10[1])philosophy conceptualized what smallest units (10[1])of matter that today name structures containing protons and neutrons? ■END■ (10[1])
