Roche Equation

Under the dome of the observatory, his wife was giving birth, and Li Qiong was observing the transit of Jupiter. The baby's first cry broke through the night sky, and he blurted out the name "Ling Po"; a moment later, his daughter was born with a tidal signal, and he saw the equation of Roche's limit and whispered "Luo tide". The nurse laughed at him for being crazy, but he said: "Every child is a love letter from the universe to the world - the stars are words and the names are commas."
