Calculus of the nervous system
Although suffering increasing ill-health, Ada Lovelace maintained her interest in mathematics and science. Her idea that she might use mathematics to understand the nervous system, suggested in this letter dated November 1844 to her friend Woronzow Greig, may have been influenced by trying to understand the effects of the strong drugs she was prescribed. And extraordinary idea at the time, mathematics and computer models are now standard in neuroscience.
神经系统中的微积分学
虽然阿达·洛芙莱斯所遭受的病痛与日俱增，但是她依然保持着对数学和科学的兴趣。她认为可以使用数学来理解神经网络。她在1844年11月写给她朋友Woronzow·格雷格的信中提出了这个想法。这可能是她在尝试理解医生开给她的强力药物带来的副作用时产生的这个念头。虽然现在数学和计算机模型已经成为了研究神经系统科学的标准，但是在当时这是一个非凡的想法。
Mathematical notes
The fascinating manuscript below has the handwriting of both Charles Babbage and Ada Lovelace as they investigate the famous "konigsberg bridge problem" This asks what patterns of "islands" and "bridges" have the property that makes it possible to find a route around them that crosses each bridge exactly once. There are also some triangles and squares that relate to the Pythagorean theorem and a "magic square" of the numbers 1 to 9, in which the sum of the rows, columns, and diagonais is always 15.
数学笔记
下面展示的这段迷人的手稿是由查尔斯·巴贝奇和阿达·洛芙莱斯在研究著名的“七桥问题”问题时同时撰写的。这个问题要求在“岛”和“桥”中找出一条可以经过所有桥和岛并且只经过一次的路径。这张手稿上还有一些跟毕达哥拉斯定理有关的三角形和正方形，还有一个“魔术方块”。这个魔术方块上写的数字只能从1-9中选择，但是每一行，每一列和每一个斜对角线的数字总和都是15。
