AHA! Moments

Welcome to C&EN's AHA! Moments.

A reader named Irv Goldman suggested to Editor-in-Chief Rudy Baum that we should consider reporting on the special moment in a chemist's career that changed that person's thinking, where a problem became crystal clear and the person said or thought, "Aha!".

We are pleased to bring you the following AHA! Moments.
