That slide is on your--is in the slides that are distributed if you want to follow on that website, there's the picture that I copied yesterday.
在发给你们的幻灯片里,如果你想在那个网站上做深入了解,这是我昨天从网站上拷贝下来的一张图片
There will be things in the class that are not covered in the readings, and may or may not be apparent from looking at the slides online, so coming to class is probably a good idea.
课上可能还会讲到阅读资料中没有的内容,可能网上的课件上也不一定包括这些内容,所以来上课才是明智之举
So, one thing they did, because it was so easy to measure kinetic energy of electrons, is plot the frequency of the light against the kinetic energy of the electron that's coming off here. And in your notes and on these slides here, just for your reference, I'm just pointing out what's going to be predicted from classical physics.
他们做的其中一件事,因为测量电子动能是很容易的,就是画出光的频率,和出射电子动能之间的关系,在讲义的这里,仅仅是,为了做个比较,我要指出,经典物理所给出的预测,这个不作为对你们的要求。
But at the end of the day, the point of the slides is not to expect you to now go write programs in C but really to just remind you that, hey, if you ever get distracted from some of the minutia that is the semicolons, parentheses, and what is very new to many of you, it's really no different than the fun and games we implemented with Scratch last week.
但是最终,我们课件上讨论的主题,并不是让你现在就写一个C语言的程序,而是要告诉大家不要你被那些分号括号,还有一些从未见过的符号等一些细节搅得心烦意乱,因为它们本质上,和我们上周用Scratch做出来的游戏,并无区别。
