In this video, we look at why the Schrodinger equation is incompatible with special relativity, specifically through the lens of Schrodinger plane waves, and the energy vs. velocity curves for relativistic and classical physics.

Stay tuned for the next videos, in which we will derive relativistic wave equations, explore the fourpotential and gauge symmetry, and eventually will return to hydrogen with a relativistic treatment of the electron! :)

For further reading, please check out Introduction to Elementary Particles, by David Griffiths. That book provides a ton of insightful context around the ideas in this quantum physics playlist.
