Physics joke

Once upon a time, all scientists in heaven played hide-and-seek games. Unfortunately, it was Einstein's turn to find someone. He plans to count to 100 and start looking. Everyone started to hide, except Newton, who just drew a square with a side length of 1 m on the ground in front of Einstein and stood in the middle. Einstein counted to 97, 98, 99, 100, then opened his eyes and saw Newton standing in front, shouting, "Newton out, Newton out." Newton said I wasn't out, because I'm not Newton. I'm standing in the middle of a square with a side length of 1 m, which means I'm Newton per square meter, so I'm Pascal!

1, you have Pascal.

A group of great scientists played hide-and-seek in heaven after their death. It's Einstein's turn to arrest people. He counted to 100 and opened his eyes. He saw everyone hiding, but Newton was still standing there.

Einstein walked over and said, "Newton, I got you."

Newton: "No, you didn't catch Newton."

Einstein: "You are not Newton. Who are you? "

Newton: "What do you see under my feet?"

Einstein looked down and saw Newton standing on a square floor tile one meter long and one meter wide, puzzled.

Newton: "This is a square meter under my feet, and I stand on it, which is Newton/square meter, so you don't catch Newton, you catch Pascal."

2. spherical chicken in vacuum

The chickens on the farm are sick. The farmer invited biologists, chemists and physicists to see what was wrong with the chicken. The biologist examined the chicken and finally said, I don't know what happened to the chicken. The chemist did some experiments and measurements, but in the end he couldn't find the reason. The physicist stood there and looked at the chicken for a while without even touching it. Then, he took out his notebook and began to write. Finally, after some terrible calculations, the physicist said, "It's done, but it only applies to spherical chickens in vacuum."
