I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, ...

In March 1905, Einstein published a paper explaining the photoelectric effect. When light falls on specific material, electrons might be emitted from its surface. This phenomenon has helped humans ...

Einstein’s heuristic argument that light consists of packets of energy or light quanta could explain the energy dependence of electrons on the frequency of light in the photoelectric effect.

Quantum mechanics looks at how things work at the atomic and subatomic levels, where particles behave in ways that seem ...

Just over 100 pages long, this small but impressive book packs a lot in for the 70th anniversary of Einstein’s death.
