Veteran, YouTube-Taught Math Student, Physicist: Josh Carroll's Journey to Booz Allen

Blog

In the 1997 movie “Good Will Hunting,” a genius janitor taught himself advanced mathematics from equations left on a professor’s chalkboard. Two decades later, Josh Carroll similarly pored over equations on YouTube—today's chalkboard—during shifts as a security guard.   

In Carroll’s case—the experience was transformative: making him a YouTube and media star in his own right. Highlights follow from Carroll’s journey from self-taught math scholar to Booz Allen physicist and technical support engineer.
