(The chapter on non-linear partial differential equations, to be precise.)

准确地讲是非性偏微分方程。

I discover that I'm not very good at geometry, but also that I excel in differential equations.

我发现我不太擅长几何，但我擅长微分方程。

How about this for the app name? The Surprisingly Helpful Equation-Linked Differential Optimized Numerator.

应用程序叫这名儿怎样 出奇-好用-微分-方程-相关 优化-计算器。

I'm telling you, the Lenwoloppali Differential Equation Scanner meets a real need. We've got a hit.

我就说嘛 莱沃帕里微分方程扫描仪满足了实际需求 咱要火了。

You know, it was the old quantum mechanics, solving partial differential equations.

你知道，这是旧的量子力学，求解偏微分方程。

In this degree, you're gonna have to go through calculus one, calculus two, calculus three, differential equations, a lot of math.

在获取学位的过程中，你必须学习微分一，微分二，微分三，微分方程，要学习大量的数学知。

Last year, I was doing differential topography at Cal Tech, and now I sketch leaves in milk foam for adult skateboarders.

去年我还在加州理工学院做微分地形学，如今却为老大不小还玩滑板的人在奶泡上画叶子。

Maxwell's main achievement was encapsulating the behavior of electric and magnetic fields into a set of differential equations, now universally known as Maxwell's Equations.

麦克斯韦的主要成就是将电场和磁场的行为封装到一组微分方程中，现在普遍称为麦克斯韦方程组。

What’d be almost as much of a lie as saying I took advanced differential calculus would be saying that Heathrow is quiet and calm.

说我学过高等微分学几乎是谎言，那就是说希思罗机场安静而平静。

The differential and integral calculus that Newton developed provided an elegant framework to measure change and area under curves, opening up new avenues in physics, engineering, and beyond.

牛顿开发的微分和分提供了一个优雅的框架来测量曲下的变化和面，开辟了物理学、工程学等领域的新途径。

Further, one might suppose that the substance which according to them underlies as matter is too mathematical, and is a predicate and differentia of the substance, ie.

此外，人们可能会假设，根据他们的说法，物质作为物质的基础过于数学化，并且是物质的谓词和微分，即。

Takes a while to derive. In Math, this word  means to obtain something from something else, to get a function or equation from another  sequence, for example, by differentiation.

需要一段时间才能得出。 在数学中，这个词的意思是从其他事物中获得某些东西，从另一个序列中得到一个函数或方程， 例如，通过微分。

So if you could imagine all those differential equations that economists write down, with all the squiggles and the swirls, to say this is what's going to happen to the economy.

因此，如果你能想象经济学家写下的所有微分方程，以及所有的曲和漩涡，那么这就是经济将会发生的情况。

The pitfalls of a pseudo-mathematical method, which can make no progress except by making everything a function of a single variable and assuming that all the partial differentials vanish, could not be better illustrated.

伪数学方法的缺陷无法得到更好的说明，除非将所有事物都作为单个变量的函数并假设所有偏微分都消失，否则它不会取得任何进展。

In fact, the problem with relativity wasn't that it involved a lot of differential equations, Lorentz transformations, and other complicated mathematics (though it did-even Einstein needed help with some of it), but that it was just so thoroughly nonintuitive.

实际上，相对论的问题并不在于它涉及许多微分方程、洛伦兹变换和其他复的数学（虽然它确实涉及——有的方面连爱因斯坦也需要别人帮忙），而是在于它不是凭直觉所能完全搞懂的。
