So, it's Newtonian mechanics, and the reason for this is because Newtonian mechanics does not work on this very, very small size scale.
牛顿力学,因为牛顿力学,在这种很小的尺度下不适用,我们说过,牛顿力学。
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。
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。
We'll come back to that, but you have to understand the structure of Newtonian mechanics.
我们等下回头再讲,不过你们要理解牛顿力学的体系框架
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“
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。
Out of postulate three it says Newtonian mechanics applicable.
从假设3我们可以知道,牛顿力学在这儿是适用的。
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
So the product of Newtonian mechanics of predicting the future given the present, has got two parts, and one is called kinematics and the other is called dynamics.
所以牛顿力学,基于现状对未来的预测,包含两个部分,一部分被称为运动学,而另一部分被称为动力学
So, that was Newtonian mechanics at work, because what did I do?
这就是牛顿力学的运用,我刚刚做了什么呢
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。
See, that's an example of Newtonian mechanics.
看到了吗,这就是牛顿力学的一个例子
So, Newtonian mechanics has two parts.
它包含两部分
So, just, if you can take what I'm saying for a moment right now that in fact this should collapse in this very small time frame, we have to see that there's a problem with one of these two things, either the Coulomb force law or Newtonian mechanics. So, what do you guys think is probably the issue here?
所以如果你们考虑我,开始说的这个塌缩应该,发生在很短的时间里,那么这两者之一就有问题,要么是库伦定律,要么是牛顿力学,你们觉得应该是哪个的问题?
So, Newtonian mechanics is our first topic.
我们先来看看牛顿力学
