Einstein discovered relativity without ever stepping into a lab—just by imagining what would happen if he rode alongside a beam of light. In this episode, we explore how thought experiments from Einstein, Galileo, and other scientific giants revolutionized our understanding of the universe, and how business leaders like Andy Grove, Brian Chesky, and Reed Hastings used the same mental discipline to solve impossible problems and build billion-dollar companies. Learn the forgotten art of rigorous imagination and how to apply it to your toughest strategic challenges.
