Students have a lot of trouble with the concepts because there is not much intuition about electromagnetic phenomenon.
学生们对于理解概念,觉得很困难,因为对于电磁学现象,只有很少能凭直觉理解的。

From next term we try to move it into the own term version of electromagnetism, which are up till now has been taught in the lecture-station format.
从下学期起我们将搬去,电磁学自己的实验室，现在这门课还是用,讲座-背诵型方式讲授。

In fact, until we do electricity and magnetism the next semester, everything's going to be based on just the laws of Newton.
其实,在下学期学习电磁学之前,所有的内容都是基于牛顿定律的

When a brief pulse of electricity is sent to the read/write head it flips on a tiny electromagnet for a fraction of a second.
当一个简单的电脉冲被送到读写头,它会短时间内出现一个小的电磁。

So, our detection devices are a little bit limited here today, we're actually only going to be using our eyes, so that means that we need to stick with the visible range of the electromagnetic spectrum.
我们今天所有的探测仪器十分有限，实际上我们要用我们的眼睛来观测，这意味着我们只能看到,电磁谱中的可见光区间。

But in hard drives where we actually have these moving platters, here is in fact, how we get from electricity and magnetism to those zeros and ones.
但是在传统硬盘中我们确实有高速运转的磁盘，这就是事实，但问题是我们如何,把电磁信号转化为0和1的。

Except for electromagnetism, the basics of mechanics, which is the motion of Billiard balls and trucks and marbles and whatnot, was set up by Newton.
除电磁学外,力学的基础,也就是台球,卡车,弹球以及其它小玩意儿的运动原理,都是由牛顿建立起来的

Newton. And he sent us on the road to understanding all the natural phenomena until the year 18-hundred-and-something when Maxwell invented the laws of electromagnetism and wrote down the famous Maxwell Equations.
他引领我们走上了探索自然现象之路,直到19世纪的某一年,麦克斯韦提出电磁学定律,并写下了著名的麦克斯韦方程组
-
And I think that's very important especially with electromagnetism, which is so numb toward if, so abstract and so much math flowing around.
我觉得这是非常重要的,尤其是对于电磁学来说，它是一门很难懂的，很抽象的学科,包含很多数学在里面。
