====== 2023-08-26 - QED ======

i've recently came across a nice explanation of electromagnetism unification on Veritasium channel:

  * [[https://www.youtube.com/watch?v=1TKSfAkWWN0|how special relativity makes magnets work]]
  * [[https://www.youtube.com/watch?v=hFAOXdXZ5TM|magnets -- how do they work]]

long story short -- magnetic field is just an electric field, viewed from a different frame of reference! this is the key insight behind [[wp>Quantum electrodynamics|QED]] and a Nobel prize in physics in 1965. nice...
