1970年,赞比亚的一位修女写信向美国航空航天局太空航行中心的恩斯特·施图林格博士提问:世界上有这么多孩子吃不上饭,为什么还要花费巨资发展探索火星的项目?施图林格博士在回信中讲述了这样一件事:400多年前,德国某小镇住着一位伯爵,他是个心地善良的人,将自己收入的一大部分捐给了镇子上的穷人。这十分令人钦佩。因为那时候穷人很多,而且经常爆发席卷全国的瘟疫。 In 1970, a Zambian nun wrote a letter to Dr. Ernst Sturinger, NASA’s Space Flight Center. Question: There are so many children in the world that can not afford to eat rice and why spend huge sums on developing the Mars exploration project In his reply, Dr. Thuringinger recounted one such thing: More than 400 years ago, a small town in Germany lived with an Earl who was a kind-hearted man and donated a large portion of his income to the town Poor people. This is very admirable. Because then the poor were many and the plagues that swept across the country often broke out.
