Math patterns of the primes
PATTERN
EXISTS
Patterns of the primes you can play with.
Interactive versions of the videos. Turn the machines, jump to a million and check the math yourself: every number on screen is computed and tested, and a conjecture is always called a conjecture.
Experiments
Checked, not guessed
Every number and claim on a page is checked by an automated test before it goes online.
Proven or conjectured
A theorem is shown as a theorem. When something is only conjectured, the page says so.
