教师节，来看看这些数学教授都说了些啥！

 

今天是教师节，这里分享一下美国数学会曾经分享的数学滑稽网页——数学教授语录（Math Professor Quotes， http://mathprofessorquotes.tumblr.com）。

这里分享一下我们口耐的数学教授们上课期间的一些代表性的语录——当然，有的可能有点雷，不喜误入！

“I teach calculus for money, I research algebra for my soul”
— Calculus professor
“我教微积分是为了挣钱，我研究代数是为了我的心灵。”
—— 微积分教授

“It’s a game, see? I give you an epsilon, and you have to find the N! It’s a very fun game, I promise.”
— Real analysis professor
“这是一个游戏，看着？我给你一个ε，你得去找一个N！这游戏非常好玩，我保证。”
—— 实分析教授

“There are no earthquakes in geometry.”
— Geometry professor
“几何里没有地震。”
—— 几何教授

“Zero is never invited to the eigenvector party.”
— Linear algebra professor
“零从来不会被邀请参加特征向量聚会。”
—— 线性代数教授

“One of you answered a problem on the test with ‘Only god knows this.’”
— Statistics professor
“你们中有个人在考试中这样答题的：‘天才知道。’”
—— 统计学教授

“A differential equation is something with a lot of x’s.”
— Differential equations professor
“微分方程就是某种包含一堆x的东西。”
—— 微分方程教授

“This isn’t mathematics, this is theology.”
— Number theory professor
“这不是数学，这是神学。”
—— 数论教授

“A problem being in NP doesn’t mean that the problem is hard. It just means that it’s slightly not easy.”
— Computer science professor
“一个问题是NP问题并不是说这个问题很难，只是说这个问题有点不太容易。”
—— 计算机科学教授

“A way to define natural numbers is by rocks–if you have that number of rocks, you have a natural number.”
— Discrete math professor
“一种定义自然数的办法就是用石头——如果你有了一堆石头，你就有了一个自然数。”
—— 离散数学教授

“When a ball is a cube, Paris is in Belgium.”
— Logic professor
“如果球是方的，巴黎就是比利时的。”
—— 逻辑学教授

“Love is NOT a symmetric relation.”
— Combinatorics professor
“爱情真不是对称关系。”
—— 组合学教授

“This is the kind of thing you think about for ten minutes and then say, “Yes, it’s obvious.””
— Graph theory professor
“这种事你思考了10分钟，然后说：‘是的，那是显然的。’”
—— 图论教授

“Whenever you make a sign mistake, you can say “Oh, but I meant modulo 2.””
— Abstract algebra professor
“无论何时你符号写错了，你都可以说：‘哎呀，我的意思是模掉了2。’”
—— 抽象代数教授

“It’s really easy to do math, you just have to know how to draw parabolas and potatoes.”
— Topology professor
“做数学真的很容易，你只需要知道怎么画抛物线和土豆就行了。”
—— 拓扑学教授

“It’s algebra, so it’s a little messy.”
— Algebraic topology professor
“那是代数，所以那有点凌乱。”
—— 代数拓扑教授
