Jacob M. Cohen, known as Conflux on Discord, is a high school student at the math-focused Proof School, located in San Francisco, California. Now a New York Times-published puzzle constructor, he has been interested in math and wordplay from a young age. He finds both of those subjects to be intrinsically fascinating and beautiful, and has spent much time exploring them.

These interests converged into Puzzles for Progress, available at puzzlesforprogress.net. It’s home to 300+ original logic and word puzzles of 100+ types; he compiled the best puzzles of the first year into a book, which you’re presumably holding!

Jacob’s non-puzzle pastimes include wasting time on the internet, writing inefficient code, following elections, blogging about nothing in particular at Chromatic Conflux (tinyurl.com/confluxblog), and writing bios about himself in third person.
