第16届“国际科学与和平周”全国中小学(江苏地区)金匙科技竞赛赛题中有这样一道十分吸引同学的题目:如果是在伸手不见五指的夜晚,人有时会被“鬼迷路”:明明是朝家的方向走,就是走不到家,直到天蒙蒙亮才发现在原地绕圈圈。鬼怪当然是不存在的,可是,这种怪事确实发生过,事情的经过听起来也非常恐怖吓人。请以《关于“鬼迷路”的研究》为题,设计一个实验,揭示这种怪现象背后的科学道理。答案:实际上,人走路时,两脚之间有一定的距离,大约是0.1米,每一步的步长大约是0.7米,由于每个人两脚的力量不可能完全一致,因此迈出的步长也就不一样,若在白天要沿直线
The 16th “International Science and Peace Week” national primary and secondary school (Jiangsu region) Golden Key technology competition title has such a topic that is very attractive to the students: If it is on the dark night, people are sometimes “ghost lost” : Obviously it is the direction of the Asahi family, that is, no one can go home and it is not until daylight that it is discovered that they are winding in circles. Of course, ghosts do not exist, but such strange events do occur. The passage of events sounds scary. Please use the title “Research on ”Ghost Lost Road“” as an experiment to design an experiment to reveal the scientific reasoning behind this strange phenomenon. Answer: Actually, when a person walks, there is a certain distance between the two feet, which is about 0.1 meters. The step length for each step is about 0.7 meters. Since the strength of each person’s feet cannot be completely the same, The steps taken are not the same, if you want to follow a straight line during the day
