What did I learn this week (2021) - 24

  1. Chiune Sugihara, a Japanese diplomat who defied government orders and saved the lives of thousands of Jews.
  2. How Fighter Jets Lock On: The primary technology that a military aircraft uses to lock and track an enemy aircraft is its onboard radar. Aircraft radars typically have two modes: search and track.
  3. The Doppler effect or Doppler shift (or simply Doppler, when in context) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.
  4. Saw a nice video editing method that bends time and space in slow motion.
  5. Learned bit about responsive images.
