古今中外成大事立大业者,都具备敏锐的观察力。爱因斯坦是一位伟大科学家,一次他询问一位朋友的电话号码,那位朋友说:“我家的电话不好记,是24361”,爱因斯坦说:“这很好记嘛,两打(12×2)19的平方”;高斯是一位卓越的数学家,八岁在小学读书,老师出了一道题:“1+2+3+…+99+100”,很多学生从1加2,加3,…挨个的加起来进行计算,惟独高斯观察出:1+100=101,2+99=101,…,50+51=101,∴1+2+3+…+99+100=101×50=5050。我们的学生,将来都是参加祖国四化的建设者,
People who have established large and important events in ancient and modern times, both have a keen observation ability. Einstein was a great scientist. At one time he asked a friend’s phone number. The friend said, “My home’s phone is not easy to remember. It is 24361.” Einstein said: “It’s a good thing, two dozen. (12 × 2) 19 squares; Gauss was an excellent mathematician, studying at the elementary school at the age of eight, and the teacher gave a question: ”1+2+3+...+99+100", many students from 1 plus 2, plus 3, ... add up to calculate, but only Gauss observed: 1+100=101,2+99=101,...,50+51=101,∴1+2+3+...+99+100 =101×50=5050. Our students will all participate in the construction of the four modernizations of the motherland in the future.
