Now, what happens is that as we do that, as we peel these skins of the onion, and we get closer and closer to the underlying law, we see that each skin has something in common with the previous one, and with the next one. We write them out mathematically, and we see they use very similar mathematics.
当我们剥下这些洋葱皮 从而接近下一层的定律时， 我们发现每一层洋葱皮和它前一层 、后一层之间都存在共性。当我们用数学把它们表示出来时 我们发现他们使用的数学是相似的。
