It was really difficult for me to shoot the old-style 'gunslinger' guns because I have tiny little baby hands and they are really large and heavy, so just the physicality of actually having to pull that off was really difficult.

So, we would actually need a really, really, really tiny velocity here to actually overcome the size of the mass, if we're talking about macroscopic particles, to have a wavelength that's going to be on the order.

是10的负34次方焦耳每秒,所以如果我们谈论的是要一个，宏观粒子有相应数量级的波长的话，我们需要一个非常非常非常小的速度来。

We figured out the mass is so tiny that it shouldn't really deflect them very much.

电子的质量这么小,对它基本不会产生影响。

So honestly, one of the best strategies in this course and in programming in general is-- generally speaking design, but it's these little tricks of the trade that will honestly make things much more fun, much more easier, and really allow you to focus on the juicy parts of the problem and not little tiny bugs that you may have started tripping over already.

说实在的，这堂课在编程方面最棒的策略之一,简而言之，就是--设计，但这只是一些让事情更简单,更容易的小技巧，让你专注于问题的核心关键,而不是一些可能让你绊倒的,这样或那样的小错误。
