Everyone at MIT has to take two terms of physics, mechanics and electromagnetism.
这里的所有学生都需要修两学期的,物理，力学，和电磁学。
-
Now this is what you learn in elementary physics and in mechanics, right.
这就是我们从基础物理,和力学中学到的。
-
And they had this feeling because there had just been this huge boon of discovery, of scientific advances that included Newtonian mechanics, it included Dalton's atomic theory of matter, also thermodynamics and classical electromagnetism.
他们会有这样的感觉,是因为他们刚，经历科学上的,大繁荣期，包括牛顿力学,道尔顿物质原子理论，热力学和电磁学,都取得了巨大进展。

Some of you are probably going to be doctors and you don't know why I'm going to do special relativity or quantum mechanics, but you don't know when it will come in handy.
你们中的有些人可能会成为医生,但你们现在不能理解,我为什么要讲相对论和量子力学,但是说不定什么时候,你就用上了呢

So, we now have this new way of thinking about how a nucleus and an electron can hang together, and this is quantum mechanics, and we can use this to come up with a new way to describe our atom and the behavior of atoms.
我们现在有了这种全新的,方法来研究电子和核子是,如何在一起的，这就是，量子力学，通过它我们,可以用一种全新的方式。
-
And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.
上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的，波动性和粒子性,和光的波动性和粒子性。

So, let's think qualitatively for a second about what that means or what the real meaning of that is. What that is telling us is that according to Newtonian mechanics and Coulomb's force law, is that the electron should actually plummet into the nucleus in 0.1 nanoseconds.
让我们定性的想想,这意味着什么,这告诉我们,根据牛顿力学,和库仑定律，电子,在0。1纳秒内,就会掉到原子核里面。
-
Or, if you're a pediatrician with a really small patient who will not sit still, it's because the laws of quantum mechanics don't allow an object to have a definite position and momentum.
或者你是个儿科医生,而你的小病人却总也坐不住,这是因为量子力学,不允许物体同时具有确定的位置和动量
