On this day in physics: 17 February 1888- Happy Birthday to Otto Stern, the Physicist with the most Nobel Prize nominations of all time, with 87 total nominations between 1925 and 1945, and actually sealing the deal in 1943 for the infamous Stern-Gerlach experiment.
Word of the day- Doppler Effect- Continuing on waves, this is a special sort of relativistic wave phenomenon. Imagine a wave such as a sound wave, such as a horn, is being emitted from a moving vehicle at constant frequency. If the car is driving towards you, because of the velocity of the car, the emitted wave will pick up a little extra speed and have a higher pitch. As it drives past you, and moves away from you, the velocity away from you will "slow the wave down a bit" and give it a little lower frequency. This is known as the doppler effect.
