It was those crazy free-wheelin' fluid dynamic '60's.

60年代行是自旋学。

If we're studying fluid dynamics, it's the number of practice problems that we've solved.

如果我们在学习学，它指是我们解决练习题数量。

The research is in the Journal of Fluid Mechanics.

这项研究已在《学》杂志上发表。

The findings were presented at the Annual Meeting of the American Physical Society's Division of Fluid Dynamics in Pittsburgh.

这一发现已经出现在匹兹堡召开美国理学会学会年度会议上。

And of course, to accomplish this, we also need to be physicists and know the underlying laws of fluid dynamics.

当然，要制作这种动画，我们还需要具有理知识，懂得动画背后学原理。

But the sailors didn't account for fluid dynamics.

但水手们没有考虑到学。

Fluid mechanics is the description of the flow of liquids and gasses.

学是描述液和气动学科。

I went into computational astrophysics and magneto hydrodynamics of star formation.

我进入了计算天理学和恒星形成磁学领域。

So, I took a class called Fluid Mechanics in college, I believe first semester, second year.

所以，我在大学二年级第一学期上了一门叫做学课。

At this point,   the principles defining crowd movement are closer to fluid dynamics than anything else.

此时，定义人群移动原则更接近学而不是其他任何东西。

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

这其中蕴含了很多有趣开放性理和学问题。

Fluid mechanics is notoriously difficult, mostly because motions of tiny things like molecules get really complicated really fast.

学 notoriously 难，主要是因为像分子这样微小东西运动会变得非常复杂非常快。

Using fluid mechanics you can work out how much lift is generated from an aeroplane's wing, or how aerodynamic a car is.

使用学，你可以计算出飞机机翼产生升有多大，或者一辆车空气动学性能如何。

[Derek] For fluid mechanics, I always expect that you have to keep the Reynolds number the same as in the real world phenomena.

- [Derek] 对于学，我总是希望你必须保持雷诺数与现实世界现象相同。

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.

我们几乎每天都要做火焰研究，我们还会做大量研究，以发现零重环境下学状况。

One might say he could see birds and flight if you look at his drawings of birds, or if you look at his drawings of water and hydrodynamics.

你看他画鸟、水或是学，就会觉得那些是真。

So the work that we do is combining fluid mechanics with problems that are relevant in health and epidemiology to understand better how pathogens are transmitted.

所以我们所做工作是将学与健康和行病学相关问题结合起来，以便更好地理解病原是如何传播。

A wing airfoil or something, shape of some kind, and you run computational fluid dynamics, you get, as a result, the drag and lift and all that stuff, right?

一个翼型截面或者某种形状，然后你运行计算学，得到结果就是阻、升等等这些东西，对吧？

Today, I'm going to tell you a story about one of nature's most extraordinary engineers that pushes the limits of fluid mechanics and bioengineering and arguably solves their No.

今天，我将向您讲述一个关于自然界最杰出工程师之一故事，他突破了学和生工程极限，并可以说解决了他们第一大难题。

Integral to marine engineering is an understanding of fluid mechanics, how water moves and how things move through water, as well as watercraft propulsion, the mechanisms used to create thrust to move marine vessels through the water.

海洋工程核心是对学理解，包括水是如何运动， 以及如何在水中移动，还包括船舶推进机制， 即用来产生推使海洋船舶在水中移动机制。
