that the laws of physics for this entire semester

整个学期的全部物理定律
certainly can be written on one of those blackboards

最多也只能写满一块黑板
or even half of those blackboards.

或者半块黑板
And the purpose of this course

这门课的目的
is to show you over and over and over again

就是要反复告诉你们
that starting with those one or two laws,

从其中的一两条定律出发
you can deduce everything,

你可以推导出一切
and I would encourage you to think the same way.

我鼓励你们用同样的方法来思考
In fact, I would encourage you to think the way physicists do,

其实即使你们不打算以后当物理学家
even if you don't plan to be a physicist,

我也希望你们能像物理学家一样思考
because that's the easiest way to do this subject,

因为这是学习这门课的捷径
and that is to follow the reasoning behind everything I give you.

也就是利用我给你的条件一步一步地推导
