Fighting all over Tiangang Invincible Hand (Physical Constants) - 36 Volts 42, summer vacation tutoring (physics subject name) - a thermal joke: after the death of Newton and Pascal, all the scientists went to heaven. One day, the scientists were playing hide-and-seek, and it was Einstein's turn to catch them. After he counted 100, he found Newton standing next to him and said, "Newton, I've caught you." "No, you're not catching Newton." "Then who are you?" Einstein asked. "Look what's under my feet?" Newton smiled slyly. Einstein saw that under Newton's feet was a square plank with a side length of one meter. "I stand on a square meter of wood, which is 'Newton/square meter', so what you catch is not Newton, but 'Pascal'." After Einstein heard this, he called Pascal. After hearing this, Pascal smiled, bent down, picked up the board at Newton's feet and said to Einstein: "I am Pascal now, right?" After that, he threw the board away. "There are no more square meters. Now, I am Newton."
