In the navy,he learned all about navigation,mathematics, mechanics,communications and electronics engineering.

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。
-
You will be able to solve all the problems we have in mechanics.
你就可以解决我们即将碰到的所有力学问题
-
This is something that you're going to prove in statistical mechanics, and so we're not going to worry about where this comes from.
我们会在统计力学中,证明这一结论，现在不需要去,操心这一结论的由来。
-
And today we'll finish that discussion, and, of course, point out actually the failure of classical mechanics to appropriately describe what's going on in an atom.
结束这部分的讨论，当然的，要指出经典力学,在描述原子内部,情况时是失败的。
-
You can actually see the mechanics of end-stopped verse quite clearly in the rhymed version of Paradise Lost that, admittedly, the great poet John Dryden wrote.
在大诗人约翰·德莱顿所写的,押韵版的《失乐园》中能很明显看到，这中孤联诗句的机制。
-
We use the adjective "Newtonian" but we don't speak of certain writers who are still interested in quantum mechanics as "Newtonian writers."
虽然我们用牛顿主义者这个词“,但是我们不会把那些,对量子力学有兴趣的人称作牛顿主义作家“
-
Maybe we can go to the mechanics of it, in case someone who's watching TV... "turn off your TV and meditate now."
也许我们能谈谈具体的一些技巧，也许有些观众。,会关上电视，开始冥想“
-
And so, you know from your Newtonian mechanics, as you were learning in 8.01, the dynamic force here mv^2/r is mv squared over r.
在8。01节对牛顿动力学系统的学习中，我们可以知道这里的运动受力,就是。
-
And so for the standard edition will you be implementing the mechanics of this game so that you can in fact play against yourself.
在标准版中，你可以为,该游戏实现这样的机制,这样，你就可以和自己对打。
-
Now, at this point we'd want to know more about the underlying mechanics about what's gone on in the case of the coma.
这时候我们就会想知道更多,昏迷状况下所发生的,更深层次的机制。
-
We're also working on the mechanics version of this in the studio format.
我们同时也希望在力学课开设,这种教学模式。
-
I mean, quantum mechanics makes sense to no human being, in my view. In those areas, people are inclined to do sort of strange things.
我的意思是在我看来，量子力学对人类完全没有意义，在那些领域，人们总是倾向于,去做有些奇怪的事情。
-
Now, I've highlighted three of these in blue here, imaging, mechanics, and biomolecular engineering because if you go on to study Biomedical Engineering here at Yale anyway, these are the things that you might pick to emphasize on.
我把这三条用蓝色字强调出来,影像学,生物机械学,和生物分子工程,如果你们继续在耶鲁学习生物医学工程,这些内容是你们必须重点掌握的
-
I'm going to now start doing simple problems in mechanics.
现在我来讲解几个简单的力学题目
-
Now, the reason this condition always holds in ordinary mechanics is because you're never, in that case, concerned with a huge statistical population of particles where the disorder among them is an issue.
这个条件在力学中总是成立,这是因为在力学中,我们从来没有关注过大量粒子的统计行为，而对这些系统来说,无序是很重要的。
-
So, remember this makes sense if you just think of it as a wave and forget the particle part of it for right now, because that would be very upsetting to think about and that's not, in fact, what's going on, we're talking about quantum mechanics here.
记住如果你们把它看做是一个波,而忘记它是一个粒子时，这就是可以理解的了，因为如果把它看做,一个粒子就行不通了，实际上也不是这样的，这里我们是以量子力学的角度来考虑问题。
-
It's just like you could say some of the principles of mechanics are very obvious, but to make an engine that operates in terms of those principles is not obvious.
这就像你能说,很多机械原理都显而易见，但是要根据这些原理,制作一个能够运转的发动机,就不那么容易了。
-
So, then we'll get to turn to a new kind of mechanics or quantum mechanics, which will in fact be able to describe what's happening on this very, very small size scale -- so on the atomic size scale on the order of nanometers or angstroms, very small particles.
然后我们要讲到一种,新的力学--量子力学,它可以解释,发生在很小尺度,大约是原子尺寸大小,也就是纳米或埃的量级。
-
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。
-
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
-
For those of you who are not from MIT, - all MIT students have to take two semesters of physics all undergraduate students. For most students this is the most rigorous exposure to physics they've ever had In the first semester of physics, they study what I think was the basic nonunion mechanics.
如果你们不是麻省理工的学生，要知道麻省理工的所有学生,所有本科生---都得学两个学期的物理,对大多数学生来说,这是他们接受的最严格的物理学习,第一个学期他们学一些,基础力学。
-
That's the result you use all the time in mechanics.
这是力学上你们经常要用的结论
-
As we said, Newtonian mechanics does work in most cases, it does work when we're discussing things that we can see, it does work even on things that are too small to measure.
在大部分情况下都适用,对我们可以看到的东西,它都能适用，甚至对一些小到,无法测量的东西它也可以适用。
-
So we are going to be studying in the beginning what's called Newtonian mechanics.
我们首先学习的是,牛顿力学
-
And I'm no scientist and I'm no specialist in sort of empirical matters, and believe me, I'm no authority on quantum mechanics, our best theory of fundamental physics.
我不是科学家,也不是实证方面的专家,相信我,关于量子力学,我并没有发言权,那可是基础物理中最经典的理论
-
But they're not accurate all the time in predicting bonding within molecules, and the reason for this is because Lewis structures are not, in fact, based on quantum mechanics.
但它们在预测分子内,成键时不总是正确的，这是因为Lewis结构，实际上不是基于量子力学的。
-
So, I will point out, in terms of MO theory, because it rigorously does take into account quantum mechanics, it starts to become complicated once we go beyond diatomic molecules.
我要指出的是，对于MO理论，以为它严格的遵守量子力学，所以一旦超过双原子分子,就变得十分复杂了。
