美国普林斯顿大学、麻省理工、弗吉尼亚州理工学院,合作一项计划,研究了三年半。研究什么?研究猫俯身伸舌头喝碟子里的牛奶时,为什么从来不会弄湿下巴的毛?三家大学的流体力学家和数学家,在想这个问题。原来早在1941年,美国的科学家就发现猫喝奶时,伸出的舌头,像一个反转过来的字母J。也就是说:舌尖向下卷,把奶很快捞进嘴巴。 Princeton University, Massachusetts Institute of Technology, Virginia Polytechnic Institute, a program of cooperation, studied for three and a half years. What do you study? Why do you never wet the chin when cats lean over their heads and drink milk from their saucer? Fluid mechanics and mathematicians at three universities are thinking about it. As early as 1941, scientists in the United States discovered that when the cat drank milk, the tongue sticking out was like an inverted letter J. In other words: the tip of the tongue down, the milk quickly saliva mouth.
