Gears within the M-209 have prime-number ratios to prevent repetitive positions—with over one million positions before the key repeats. The M-209, however, is not fully secure, partly because its prime numbers are short. #MathAtSFO #Mathematics #Math#cryptology#cipherThis tweet was posted on March 28, 2022.
An outsider cannot unscramble the code without knowing the secret letter. But if many messages are sent, an enemy can statistically detect the pattern of the device and the secret key.

Creating a Klein bottle is impossible in our universe—you need four spatial dimensions! In our 3-D universe, every Klein bottle must have a self-intersection, where tubing crosses through a wall. #MathAtSFO#Mathematics#KleinbottleThis tweet was posted on October 25, 2021.
