Today we've got an episode about a mysterious figure in the online math world.

They disappeared years ago, but they're still sparking debate and speculation.

We all love a good puzzle. Some people have their crosswords.

Some people play Sudoku.

Other people are still doing wordle.

But Ron Gordon, a patent agent and a former physicist in Massachusetts,
