Einstein and Light - Deepstash

Einstein and Light

Albert Einstein did not think about symmetry when he wrote his first relativity papers in 1905. He was considering several seemingly unrelated puzzles and connecting the dots.

  • Einstein realized that the speed of light - a speed that stayed constant - was a measurable manifestation of the symmetrical relationship between electric and magnetic fields.
  • Light didn’t need anything to travel through because it was itself electromagnetic fields in motion.
  • There was no universal here and now.
  • It took some years for Einstein to acknowledge that space and time are interwoven and impossible to disentangle.
