So, Marsden came up with the model, and as you go through 8.02 and you understand electrostatics and electrodynamics, you'll be able to do this analysis.
后来马斯登提出了这个模型,就像你们通过8。02的考试一样2,你们学过了静电学和电动力学,你也能做这些分析。
So, this is exactly how Rutherford did discover that these particles were present and made this new model for the atom that we now know has both a nucleus, and we know the size, and also has electrons.
他提出了一个,新的原子模型,这里面有一个原子核,和一个电子,原子核的尺寸是知道的。
Well, so far we've had two models that have been thrown out to you: From polytheism's worship of many gods there's a natural evolution to henotheism's elevation of one god to a supreme position.

So, I said I'd tell you a little bit more about where this Bohr radius came from, and it came from a model of the atom that pre-dated quantum mechanics, and Neils Bohr is who came up with the idea of the Bohr radius, and here is hanging out with Einstein, he had pretty good company that he kept.
我要告诉你们,波尔半径是从哪里来的,它起源于前量子力学时代的,原子模型,尼尔斯,玻尔提出了,波尔半径的概念,这是他和爱因斯坦在一起,他们是好朋友,当我们讨论这个原子模型时你们要记住的是,在1911年。
