It was 3:00 AM, the "witching hour" for engineering students, and Elias was staring at a problem in (TC7) by Louis Leithold that seemed to defy the laws of physics and logic. Years later, Elias kept his tattered copy of
Elias had found a PDF of it on an old, flickering monitor in the basement lab. As he scrolled through the digital pages of the , it felt like finding a map to a buried treasure.
