I will let it swing one oscillation, and when it comes to a halt here, I will start the timer.

我让它，摇摆一个来回，当它停在这里，我将开始计时。

Well, you can think about the physics, actually. When I start this oscillation, I have a choice of two things.

你可以想想，物理有关的，事实上，当我开始振荡，我有两种选择。

And I couldn't be happier, because this tells me that the motion is that of a simple harmonic oscillation.

我们很高兴地发现，这个告诉我们，这个运动，是个简单谐波运动。

It's the same as when you hit two tuning forks at the same time, and hear a low-pitched oscillation in the background.
