P.S. Fun with QED-quod erat demonstrandum

In the world of physics most people translate QED as Quantum Electrodynamics... if you really want to have fun, interchange QED with the original QED of physics..."quod erat demonstrandum".

Most physics professionals today have forgotten that QED was once common for this Latin phrase. It literally translates in "what was to be proven" and is a common way of identifying the conclusion of a mathematical or logical argument.

It is the cornerstone of scientific pursuit.

Consequently QED is not QED.
