Thought Experiments
Manage episode 384148019 series 3517317
When Einstein was 16, he appears to have conducted his first thought experiment, imagining what things would look like if he travelled on a beam of light. This was an approach he'd continue to use throughout his career of using thought experiments to investigate the mysteries of the universe, an approach other great Theoretical Physicists of the 20th century like Bohr and Schrodinger would emulate to explore the mysteries of the quantum. Indeed some of the greatest experiments of the 20th century didn't happen in the lab but in the imaginations of some of the most gifted scientists in history.
