1963年,坦桑尼亚的马干中学初三年级的学生姆潘巴偶然发现一个奇怪的现象:他把冷热不同的两杯牛奶同时放入冰箱中,过一段时间后观察发现,热牛奶已经结成了冰,而冷牛奶竟仍是很稠的液体!姆潘巴满怀疑惑地去请教他的物理老师。可是他的物理老师武断地认为那是不可能的,一定是姆潘巴搞错了。姆潘巴升人高中又去请教他的高中物理老师,但仍未得到满意的回答。不久,达累斯萨拉姆大学物理系主任奥斯·玻恩博士访问该校,姆潘巴借此机会向玻恩请教:“如果取两个相似的容器,放人等容积的水,分别为35℃和100℃,把它们同时放人
In 1963, Mpamba, a third-year student from Tanzania’s Makan Middle School, stumbled upon a strange phenomenon: He put two different kinds of hot and cold milk in the refrigerator at the same time. After a while, he observed that hot milk had been formed. The ice, but the cold milk is still a very thick liquid! Mpmba wondered to ask his physics teacher. However, his physics teacher arbitrarily thought that it was impossible. It must have been a mistake by Mpamba. Mpamba went to high school to ask his high school physics teacher, but he has not yet received a satisfactory answer. Soon, Dr. Osbourne, the director of the Physics Department of the University of Dar es Salaam, visited the school. Mpamba took the opportunity to ask Bonn: “If you take two similar containers and put equal volumes of water, For 35°C and 100°C, release them simultaneously
