Why Did Newton Have Mental Illness Later in His Life?
牛顿晚年为何会精神失常？
红人自画像
大家都听说过那著名的苹果落地的故事吧：一位青年在苹果树下专心读书，突然一只苹果从树上直落下来。这位青年陷入了沉思，从而发现“万有引力定律”，这位青年就是我——牛顿。
All of you must have heard about the story of the falling apple: A young man was concentrating on reading under an apple tree. Suddenly, an apple fell straight down. The young man then fell into contemplation and was inspired to formulate the Universal Law of Gravitation. I am that young man—Newton.

古古和同学们从小就听大人们讲牛顿的故事，以及牛顿由于专心工作而闹出的笑话，然而这位偶像级科学家却在50岁时精神失常了。这究竟是怎么回事呢？古古决定探望他。
Since childhood, Gugu and his classmates have heard about Newton’s stories, including that famous anecdote about his over-concentration on his work. But the star scientist had mental illness later in his life. What was wrong? Gugu felt worried and decided to call on him.
(G=Gugu N=Newton)
G: How are you doing, great scientist?
N: Fine. I just can't fall asleep everyday, feeling a bit uncomfortable.
G: You need to take a good rest. You're too devoted to work and I heard that you once boiled your pocket watch as an egg. If you go on living under such great pressure, your health would be damaged.
N: Indeed. Sometimes I feel exhausted. Moreover, my mother passed away the other day. I’m so sad.
G: Sorry to hear that.
N: That’s not the end. After that, I went back to Cambridge. One morning, I came back from church only to find the manuscripts on optics and chemistry and some other papers were all burned to ashes.
G: That’s too awful.
N: You see. I just can’t help but feel bad. Everyday I live in gloom.
G: Come on! You have to take care. Just cheer up!
古古：大科学家，您好吧！
牛顿：噢，挺好的。就是最近有些不舒服，天天都睡不着。
古古：您要多注意休息啊，您太专注工作了，听说您曾经把怀表当作鸡蛋煮。长期如此会影响健康的。
牛顿：是啊，有时我的确太累了。更糟糕的是，前几天，我母亲逝世了。我陷入极度的悲伤痛苦之中。
古古：那真不幸。
牛顿：坏事并没有结束，办完母亲的丧事，我回到了剑桥大学，一天早上，我从教堂做完祈祷回来，发现书桌上有关光学和化学的手稿及一些论文全部被烧毁了。
古古：太倒霉啦。
牛顿：我难过极了。每天的心情都糟透了。
古古：唉！您要珍惜自己的身体，乐观一点哦。
