Ok, time for some real discussions on TF. Tell us which law of physics you like most!
For me, I just love the Doppler effect! Don't you just have to love those cows standing in the field staring with wide eyes at the passing trains? One can only imagine what goes on in their brain at that time. I bet they are calculating the frequency of the sound of the train in relation to the distance of it (in real time of course)!
Come on Thai girls, I know you get all excited about physics. What is your favorite law of physics?
