He wrote his doctoral thesis on electromagnetism.

他写有关电磁学的博士论文。

Magnetism is one part of a dual force, electromagnetism.

电磁。

No force — not gravity or electromagnetism or anything — can cross it.

没有任何力量——重力、电磁或任何东西——能穿过它。

How electrons begin to move in the first place is a result of a force of nature called electromagnetism.

电如何开始运动是一种被称为电磁力的自然力的结果。

Electrons are bound to an atom’s nucleus by electromagnetism.

电通过电磁作用核结合。

Electromagnetism also explains all of electricity.

电磁学也释所有电现象。

Quantum mechanics can describe electromagnetism and the strong and the weak force that works inside atoms, but it can't describe gravity.

量力学可以描述电磁力和内部的强力和弱力，但不能描述引力。

Today we learned about Maxwell's equations and their unifying power in the field of electromagnetism.

今天我麦克斯韦方程组及其在电磁学领域的统一力量。

Dark matter is stuff that interacts with gravity but not electromagnetism, so can be felt, but not seen.

暗物质是引力相互作用但不电磁相互作用的物质，因此可以感觉到，但看不到。

But he put them together, to create a new, complete understanding of electromagnetism.

但他将它放在一起，创造对电磁学的全新理。

This leads us to electromagnetism: the description of magnets, electricity, or more generally, electric and magnetic fields.

这引出电磁学：对磁铁、电或更广泛地说，电场和磁场的描述。

So you can see why electromagnetism is an incredibly important force, and this isn't the only important application of it.

所以你可以明白为什么电磁力是一种极其重要的力量，而且这并不是它唯一重要的应用。

But you can't forget everything you've learned about electromagnetism yet, because it's coming back in a shiny new form, known as light!

但是你不能忘记你所学到的关于电磁学的一切，因为它以一种闪亮的新形式回来，被称为光！

Later we'll learn about how electric forces and fields are just half of the story in our pursuit of understanding the larger concept of electromagnetism.

稍后我将到电力和电场 关于我对电磁学的理，这只是故事的一半。

That year, Morse was traveling to the United States from Europe on a ship, when he overheard a conversation about electromagnetism that inspired his idea for an electric telegraph.

那一年，莫尔斯乘船从欧洲前往美国，当时他无意中听到一段关于电磁学的谈话，这激发他发明电报的想法。

On one end we describe how the fundamental particles work and interact with each other with quantum field theory which explains electromagnetism and the nuclear strong and nuclear weak forces.

一方面，我用量场论描述基本粒如何工作和相互作用，该理论释电磁学以及核强力和核弱力。

It goes back to the fact that we have two kinds of forces that are present that we call electricity or electromagnetism, and those two forces are the electric force and the magnetic force.

我有两种力，将其分别称为电或电磁，这两种力就是电力和磁力。

It was a Physicist called James Clerk Maxwell who discovered that these are two aspects of the same thing and derived the wonderfully elegant rules of electromagnetism and theorized that light was an electromagnetic wave.

一位名叫詹姆斯克拉克麦克斯韦的物理学家发现这是同一事物的两个方面，并推导出极其优雅的电磁学规则，并提出光是一种电磁波的理论。

But the vast knowledge of electromagnetism that we have today, and the doors it has opened into the fields of relativity and quantum theory, are all based on the theories that Maxwell and his predecessors developed.

但是今天我对电磁学有广泛的，在相对论和量论领域打开的大门都是基于麦克斯韦及其先进前辈的理论。

Even the basic forces we see today — gravity, electromagnetism, and the two nuclear forces responsible for holding atomic nuclei together as well as letting them disintegrate in radioactive decay — were all squeezed together into one unified super force.

即使是我今天看到的基本力——重力、电磁力，以及两种使核结合在一起并使其在放射性衰变中体的核力——都被挤在一起形成一个统一的超级力。
