Because they happen to be my area of expertise as an engineer, in fluid dynamics.

这恰好是我的专业领域 作为一名工程师，在动学方面。

But the real culprits were two scientific phenomena: buoyancy and fluid dynamics.

但真正的罪魁祸首是两种科学现象：浮和动学。

So, in order to grasp the essentials of fluid dynamics, let’s just do some pretending, shall we?

那么，为了掌动学的本质， 让我们假装一下， 好吗？

And so there are a lot of interesting, open problems of physics and fluid dynamics embedded in it.

因此，其中嵌入了许多有趣的、开放的物理学和动学问题。

Their scientific work in plasma fluid dynamicswill have deep implications for how we understand our universe.

他们在等离子动学方面的科学工作将对我们如何理解宇宙产生深远的影响。

Today, that concept is known as Pascal's Principle, and it's the reason hydraulics are so useful.

今天，这条定律被称为帕斯卡定律， 这就是动学如此有效的原因。

And in the world of fluid dynamics, if I pulse an air jet in one direction I basically pull air with it.

在动学领域，如果我向一个方向呼出空气，其实我也是在拉动空气。”

He had to be acquainted with meteorology and know enough fluid dynamics to make sure he didn't overload his ship with booty.

他还得熟悉气象学，并掌足够的动学知识，以确保他的船有因战利品而超载。

You have to have a lot of mechanical designers and product designers but also you have to have a lot of fluid dynamics, motor engineers, software people, ballistics people.

你必须有很多机械设计师和产品设计师，但你也必须有很多动学电机工程师，软件人员，弹道学人员。

We were doing flame research almost every day and then a lot of fluid research to see what`s going on with fluid dynamics up in zero g.

我们几乎每天都在进行火焰研究，然后进行大量研究，以了解动学在零重下发生了什么。

But, the science behind these things: how wood burns, how airflow works, if you start thinking about fluid dynamics inside of a cooker, then science has a pretty huge part of it.

但是，这些事情背后的科学：木头是如何燃烧的，气的原理，如果你开始思考炊具内部的动学，那么科学就占了很大一部分。

And so, it's like a different lens, allowing us to see the answers to questions like, " What about combustion? " " What about fluid dynamics? " Now, sleeping is delightful.

因此，它就像一个不同的镜头， 让我们看到诸如“燃烧如何？ ”“动学如何？ ” 等问题的答案， 现在，睡觉是愉快的。
