It's gonna be a pretty stupid demo if that was the smallest, but here we go.
如果这个就是最轻的,那这似乎是个,很无聊的演示,我们继续。
All right. So let's test what we, in fact, know about the photoelectric effect, and before we do that actually, we're going to calculate what we would predict, so when we do the demo it will be meaningful and we can tell whether we're successful or not.
好的,我们来测试一些,我们实际上懂了,多少光电效应的东西,在我们做测试之前,我们先算一下我们能预知什么,这样我们做的测试会很有意义,并且也知道我们是否成功了。
Now at Harvard Thinks Big I happened to tear into this thing myself and it would seem a little pointless to re-hash that same demo so instead I thought I'd solicit an ideally sufficiently strong volunteer to come on up.
现在在“哈佛大梦想”的讨论会上,我反复思考这件事,觉得再演示一遍似乎意义不大,因此我想找一位合适的志愿者,上讲台来。
And when we talked about that, what we found was that we could actually validate our predicted binding energies by looking at the emission spectra of the hydrogen atom, which is what we did as the demo, or we could think about the absorption spectra as well.
当我们讨论它时,我们发现,我们可以通过,观察氢原子,发射光谱,来预测,结合能,就像我们在演示实验里做的那样,或者我们也可以观察吸收谱。
I taught I'd demo just a couple little snippets with this.
我已经教过了。
This demo needs a little work next year.
明年这个演示也会比较费事。
So your role in here in this demo is to get an int from Jordan.
所以你在这个演示里面的角色是,从Jordan那里获取一个int数。
- So now if Christiana doesn't actually -- if either programmer or who's programming these little puzzle pieces, don't actually do anything with this return value, and I call, get int, she wants to hand this piece of paper -- to me, but if I don't actually assign -- no, no, I just messed up the demo.
现在如果Christiana没有-,如果程序员或谁在编写这段代码,不要对这个返回值做任何事情,我调用GetInt,她把这张纸给我,但是如果我没有赋值-,不,不,我刚才把这个演示搞乱了。
