一个体重70千克的人,体内包含:45升水、足够染白一个鸡棚的钙、做成2200根火柴需要的磷、70块肥皂用的脂肪、打2英寸钉子所需的铁、做9000根笔芯所需的碳、一勺镁。我不止70公斤。我记得有一个叫作“宇宙”的节目,卡尔·萨根在貌似宇宙空间的布景前晃来晃去,口若悬河。一集节目中,他坐在一个装满制造人类所需原料的缸子跟前。他用一根棍子在缸子里搅拌,想知道他能不能造出生命来。 A body weight of 70 kg, the body contains: 45 liters of water enough to dye a chicken shed calcium, making 2200 matches need phosphorus, 70 soap fat, playing 2 inches nail iron, do 9000 Refill the required carbon, a spoonful of magnesium. I am not only 70 kilos. I remember having a program called “The Universe,” with Carl Sagan dangling in front of a seemingly cosmic space. In one episode, he sat in front of a tank full of ingredients needed to make mankind. He stirred in a cylinder with a stick, wondering if he could make life.
