When the clip is playing, he can wave a palm at the screen to call up the controls to rewind the video or turn up the volume.

当视频播放时，他可以对着屏幕挥动手掌激活控制菜单，倒回视频或者调高音量。

New research suggests that mindfulness meditation can help relieve pain and improve memory by regulating a brain wave known as the alpha rhythm, which "turns down the volume" on distractions.

新的研究表示冥想可以通过管控阿尔法脑波节律，减少分神来帮助减轻疼痛，提高记忆力。

Adjust the frequency, volume, and harmonic content and you can see and hear how the wave changes.

调整频率、体积和谐波内容，你就可以看到和听到波是怎么变化的。

That should make sense to us, because when we talk about a wave function, we're talking about a probability divided by a volume, because we're talking about a probability density.

因为我们说，波函数,是概率，除以体积,因为我们说的是，概率密度，如果我们用它。

So, what we can do to actually get a probability instead of a probability density that we're talking about is to take the wave function squared, which we know is probability density, and multiply it by the volume of that very, very thin spherical shell that we're talking about at distance r.

我们能得到一个概率,而不是概率密度的方法,就是取波函数的平方，也就是概率密度，然后把它乘以一个在ｒ处的,非常非常小的,壳层体积。
