1 00:00:00,000 --> 00:00:02,000 A geometric map of numbers 2 00:00:03,800 --> 00:00:06,800 Every point on this circle encodes a rotation 3 00:00:09,066 --> 00:00:11,066 As theta grows, the point rotates around the circle 4 00:00:19,466 --> 00:00:22,466 At theta equals pi, the point lands at negative one
