[Homework]2012-03-28 阿尔伯特·爱因斯坦 Einstein—7

HW

But you know Issac Newton himself was not satisfied by that. Objects move because they are pushed  not pulled Objects move because they are pushed. So what is pushing this, Newton didn't know. So Newton simply threw his handsome   and said I don't know. So I am inventing something called gravitational pull.

And Einstain said , no this theory can be right.
He was prepared simply go I really want to solve this problem , I want to briliantly understand the whole universe .

ax Plank said to him , you can work on gravity if you want to but  two problems.

You are not going to be successful the problem is too hard.

And if you do, no one will believe you.

It's an extremely difficult task . It's not clear where to begin or how to go about doing it at all . Ultimately the thing that gives him that clue turns out to be his fateful way of reasoning , the thought experiment.

To * you and I would called daydreaming but he calls it thought experiment because he is Einstain .

He is in his patent office looking out the window . He imagine a man working on the roof and he begins to wonder what would happen if one of those man which fall off the roof .

And then he had the happiest thought of his life, the inspiration of the ages .

He had a vision the man will not actually be feeing his own weight, He would be weightless

And then he imagine if you are in a elevator and somebody cuts the cord  what happens to you? You fall, but the elevator falls the same as you do. You are weightless inside the elevator  . So then  Einstain got it.

It is as though gravity which has been switched off , what's really going on?

The reason such thing has gravitional fall ,the earth has curved the space around me and space is pushing me into this chair space itself can be curved.
