Albert Einstein - The Size and Existence of Atoms

The video explores Einstein's contributions to physics, starting with his explanation of the photoelectric effect and moving to his work on Brownian motion. Brownian motion, the random movement of particles in fluids, provides evidence for the existence of atoms. Einstein mathematically described this motion and used it to estimate the size of atoms, demonstrating a clever approach to understanding the unseen world of particles.

What was the role of the photoelectric effect in Einstein's exploration of physics?

Discuss the relationship between the movement of particles in fluids and the concept of atoms.

What is Brownian motion and how does it relate to the existence of atoms?

Explain the significance of Einstein's work on Brownian motion.

How did Einstein derive the size of atoms from Brownian motion?
