故事一:第20只凸透镜一次科学课后,学生刚从实验室回到教室,实验员便告知我,实验室少了一只凸透镜,怀疑是我班学生刚才带走了。首先想到的办法是:搜学生的抽屉或书包,这可能会找到,但肯定会让那个拿凸透镜的学生遭到别人嘲笑或者诬陷。一只凸透镜不易查出来,那么几只呢?十几只呢?灵光一闪。想到了第二个办法。先要求学生由班长和体育委员组织,在走廊上静立5分钟,我则趁此机会到实验室借了19只凸透镜。丢失的一只还没找回来,又来借19只,实验员满腹狐疑。
Story one: the first 20 convex lens After a class of science, students just returned from the classroom classroom, the experimenter told me that the laboratory less a convex lens, suspected to be my class just taken away. The first thing to think of is: searching for a student’s drawer or school bag, which may be found, will certainly make the lenticular student laugh or fraudulent. A convex lens is not easy to find out, then a few? Ten only? Emmanuel flash. I came up with the second solution. Students are required to be organized by the squad leader and sports commissioner for 5 minutes in the corridor. I took this opportunity to borrow 19 convex lenses in the lab. Lost one has not recovered, but also to borrow 19, full of suspicions laboratory technicians.
