一、勾股定理趣闻二则1953年,中国科学考察团出国考察.途中,著名数学家华罗庚出上联“三强韩赵魏”.让同行的钱三强、张钰哲、赵九章、贝时璋、吕淑湘等对下联.一时,几人都被难住.最后,还是华老把下联对上了:九章勾股弦.此联巧在明镶暗嵌.上联明镶,三强即战国时期的韩、赵、魏三国;暗嵌,指“钱三强”.下联明镶,九章,指首次记载我国古代数学家发现勾股定理的一部数学著作;暗嵌,指“赵九章”.华老此联,确有独到之处!
First, the Pythagorean theorem anecdotes two In 1953, the Chinese scientific expedition to study abroad on the way, the famous mathematician Hua Luogeng out on the “top three Han Zhao Wei.” Let the peer money Sanqiang, Zhang Yuzhe, Zhao Jiuzhang, Tony When Zhang, Lv Shuxiang, etc. on the next couple. At the moment, a few people are stumped. Finally, or the old couple put on the next: nine chapters of the string. That is, the Han Dynasty, Zhao, Wei three kingdoms during the Warring States period; secretly embedded, refers to the “money Sanqiang.” Under the Ming set, nine chapters, refers to the first record of ancient Chinese mathematicians found the Pythagorean theorem of a mathematical work; Refers to “Zhao Jiu Zhang ”. Old couplets, indeed unique!
