We found a new pattern in the primes! One that we didn't know was there. Primes don't like to repeat their last digits. It's really, really strange. A prime could end with a one, three, a seven, or a nine. I mean the exceptions are two itself, which obviously end in a two and five itself. But apart from that, they end with a one, a three, a seven, or a nine, right. And because we hope that primes are random, or they feel like they kind of appear randomly, that each one of those should be equally likely and something strange has happened, so some mathematicians in Stanford have looked at this and they've looked at consecutive primes and they've noticed things like if a prime ends in a nine, it's actually more likely to, for the next prime to end in a one, rather th...
