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

准确地讲非线性偏方程。

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

我发现我不太擅几何，但我擅方程。

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，你必须学习积一，积二，积三，方程，要学习大的数学知识。

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

你知道，这旧的子力学，求解偏方程。

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.

麦克斯韦的主要成就场和磁场的行为封装到一组方程中，现在普遍称为麦克斯韦方程组。

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的所有方程，以及所有的曲线和漩涡，那么这就经济会发生的情况。

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