Spotlight on the Doppler effect

If you have ever stood on the side of a highway, or an ambulance passed you by at high speed, you must have noticed the change in tone that occurs exactly when the vehicle or the siren passes you by: the noise "drops" sharply from high to low tones, from treble to bass.

when the vacuum was first discovered

  • 4 תגובות
The Italian physicist Evangelista Torricelli was born in Rome to a humble and poor family. Although luck was not in his favor, his hard work paid off. He managed to reach the top of the Italian Academy and worked with the great scientist of the time, Galileo Galilei. His curiosity led his country, and then the entire world, towards a solution to a riddle that is more than two thousand years old - what is the nature of the vacuum? Torricelli's way of solving the problem was based on a simple experiment that contained a flask, a glass tube and mercury.
