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

准确地讲是非线性偏程。

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.

在获取学程中，你必须学习积一，积二，积三，程，要学习大数学知识。

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

你知道，这是旧子力学，求解偏程。

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.

麦克斯韦主要成就是将电场和磁场行为封装到一组程中，现在普遍称为麦克斯韦程组。

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所有程，以及所有曲线和漩涡，那么这就是经济将会发生情况。

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，相对论问题并不在于它涉及许多程、洛伦兹变换和其他复杂数学（虽然它确实涉及——有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。
