数学家和天文学家,班哲明.班尼卡出生,1731119

1752年,班尼卡的注意力,完全被一个木头做成的时钟所吸引 。这是美洲第一个由此方式做成的时钟,在长达十年的时间里都可以精准地报时。20年之后,,他成功的预测 到1789年的日蚀 现象,反驳了那些知名天文和数学家的推论。他的能力震撼了许多人,包括托马斯杰弗逊,邀请他成立团队为华盛顿区丈量,也就是今日我们的首府所在地。

闲暇之时,班尼卡撰写有关宾州、德拉瓦、马里兰和弗吉尼亚的农民历及星象历书。农民历包含医药和治疗的知识、列出班尼卡自行计算河流、潮汐的信息、和日月蚀的时间。
17911802年,他每年出版一本历书。


In 1752, Banneker attracted attention by building a clock entirely out of wood. The first ever built in America, it kept precise time for decades. Twenty years later, Banneker again caused a stir, when he successfully forecast a 1789 solar eclipse. His correct prediction contradicted those of better-known mathematicians and astronomers. Banneker's abilities impressed many people, including Thomas Jefferson, who recommended him for the surveying team that laid out Washington, D.C., making it the monumental capital it is today.

In his free time, Banneker wrote the Pennsylvania, Delaware, Maryland, and Virginia Almanac and Ephemeris. The almanac included information on medicines and medical treatment, and listed tides, astronomical information, and eclipses calculated by Banneker himself. He published the journal annually from 1791 to 1802.
