Perhaps you think you have come to math or physics.
也许你认为你已经学好了数学或者物理。
We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.
我们并不想每次都去解薛定谔方程,而且实际上,一旦我们开始讨论分子,我可以想象,你们中没有一个人,不管你有多么热爱数学或物理,会想去解这种情况下的薛定谔方程,总之,路易斯结构能让我们,有超过,90%,的概率判断出正确的,电子排布。
We are bodies in motion, and who cannot help but obey the law or the physics of attraction and repulsion.
我们处在运动状态,这是无法控制的,只有遵循规律,或者引力和斥力的规律。
And every physical object, or every purely physical object, is subject to deterministic laws because the laws of physics are deterministic.
而每个物理实体 或者说每个纯粹的物理实体,都遵从着确定性的定律,因为物理定律是确定性的
And so this is not like a math problem set or a physics problem set. Or, like a high school physics lab, where we all know what the answer should be, and you could fake your lab results anyway.
或是物理问题集合,又或者是高中的物理实验室,我们对这些问题都有确切的答案,或者你可以把你的实验结果改成正确的,有些事情是不能明确界定的。
Science, particularly more advanced sciences like physics or chemistry, are all about unobservables.
科学,尤其是像物理,或者化学这样较为尖端的科学,研究的都是不可观测的事物。
Whether you are going into physics or not is irrelevant.
这和你是否学物理专业并不相关
We have the pulse being slowed down and almost like a law of physics or something, now comes a reaction- now John Kander makes the music accelerate so let's watch a wonderful example of accelerando here.
这里我们听到节奏慢了下来,但是,与物理类似,反作用出现了,现在约翰·肯德尔加快了音乐的节奏,让我们看到了一个渐速音的好例子
We've learned a lot about the mechanics of how humans work as organisms over the last 100 years or so, how we work as sort of physical objects that have to obey the laws of physics that you know about.
在过去一百多年间,我们已经了解很多,人体作为一个,有机组织的工作机理,以及人体作为一个物理实体,遵循人所共知的那些物理定律的原理
It's one thing to know your place in the universe, or to know the fundamental laws of physics.
知道自己在宇宙中的位置,或知道物理的基本定律是一回事。
Politics political science he tells us in the Ethics again is not a theoretical subject in the matter of physics or metaphysics or mathematics.
政治,政治科学,他在《伦理学》中再次告诉我们的,并非理论性主题,见诸物理学,形上学或数学。
So that's what we are going to focus on, and you will find out that the laws of physics for this entire semester certainly can be written on one of those blackboards or even half of those blackboards.
这就是我们的课程重点,而且你将来会发现,整个学期的全部物理定律,最多也只能写满一块黑板,或者半块黑板
So, for example, when people, and we'll talk about this next class, were looking at different characteristics spectra of different atoms, what they were seeing is that it appeared to be these very discreet lines that were allowed or not allowed for the different atoms to emit, but they had no way to explain this using classical physics.
举个例子,当大家看到,不同原子的特征光谱时,他们看到的是一些分离的线,那可以使不同的原子,发射或不发射出去,但是这些无法用经典物理来解释。
