He also showed how one can make sense of adding and multiplying infinities.

他还演示了如何能理解将各种无穷大相加和相乘。

After all, physicists never see real infinities in nature, nor do they want to!

毕竟，物理学家从未在自然界中见过真正的无穷大，他们也不想见到！

In order to taste the infinities of life, they begin early and never go slowly.

为了把无限的生活都品尝一遍，他们抓紧时间、从不懈怠。

He feels himself buried in those two infinities, the ocean and the sky, at one and the same time: the one is a tomb; the other is a shroud.

他觉得自己同时被两种广大无边的东西所掩埋：海和天，一种是墓穴，一种是殓衣。

By tweaking certain values in the models, physicists could avoid these infinities and calculate properties of particles that corresponded to reality.

物理学家可以借由调整模型中的某些参数来避开无穷大，并且计算出粒子的实际性质。
