## Unscramble the Blue Letters

We didn't know for almost 40 years until fnark Nelson Cole came along. And at a gathering of prestigious aciamren mathematicians, he walked to the board, took up a piece of chalk, and srteatd writing out the powers of two: two, four, eight, 16 — come on, join in with me, you know how it goes — 32, 64, 128, 256, 512, 1,024, 2,048. I'm in geek heaven. We'll stop it there for a second. Frank Nelson Cole did not stop there. He went on and on and cuclaeltad 67 perwos of two. He took away one and wrote that number on the board. A frisson of enmcetxeit went around the room. It got even more exciting when he then wrote down these two lgrae prime numbers in your standard multiplication fraomt — and for the rest of the hour of his talk Frank Nelson Cole busted that out. He had found the prime factors of (2 ^ 67) - 1. The room went berresk — (Laughter) — as Frank Nelson Cole sat down, having delivered the only talk in the history of mathematics with no words. He admitted afterwards it wasn't that hard to do. It took focus. It took dedication. It took him, by his estimate, "three years of Sundays."

## Original Text

We didn't know for almost 40 years until Frank Nelson Cole came along. And at a gathering of prestigious American mathematicians, he walked to the board, took up a piece of chalk, and started writing out the powers of two: two, four, eight, 16 — come on, join in with me, you know how it goes — 32, 64, 128, 256, 512, 1,024, 2,048. I'm in geek heaven. We'll stop it there for a second. Frank Nelson Cole did not stop there. He went on and on and calculated 67 powers of two. He took away one and wrote that number on the board. A frisson of excitement went around the room. It got even more exciting when he then wrote down these two large prime numbers in your standard multiplication format — and for the rest of the hour of his talk Frank Nelson Cole busted that out. He had found the prime factors of (2 ^ 67) - 1. The room went berserk — (Laughter) — as Frank Nelson Cole sat down, having delivered the only talk in the history of mathematics with no words. He admitted afterwards it wasn't that hard to do. It took focus. It took dedication. It took him, by his estimate, "three years of Sundays."
