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),而是在于它不是凭直觉所能完全搞懂的。
