CORRECTIONS

- At 06:28 the graphics are wrong: the 10p should have moved out, not the 1p. My code and what I say are all correct. First spotted by @toolowforzero

- At 16:19 the bottom of the sigma should be

little n to read “n = 1”, not big N. First spotted by @andreysmirnov5482.

- Let me know if you spot anything else!
