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

60年代行的是自旋学。

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，它指的是我们解决的练习题数量。

The research is in the Journal of Fluid Mechanics.

这项研究已在《学》杂志上发表。

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.

你看他画的鸟、水或是学，就会觉得那些是真的。

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，我们还会做大量的研究，以发现零重环境下学的况。

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

当然，想要制作这种动画，我们还需要具有物理知识，懂得动画背后的学原理。

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的美国物理学会学会年度会议上。

But the sailors didn't account for fluid dynamics.

但水手们没有考虑到学。

MUKUL SHARMA: " That's precisely what we were doing, was looking at fluid mechanics, chemistry, and so on… and applying all that knowledge to making hydraulic fracturing process better." " Hydraulic fracturing" is the industry term for fracking.

Mukul SARMA：“这正是我们正在做的事情，研究学、化学等… … 并应用所有这些知识来改进水压裂过程。 ” “水压裂” 是水压裂的行业术语。

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.

海洋工程的核心是对学的理解，包括水是如何运动的， 以及物如何在水中移动，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的机制。

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，然后你运行计算学，得到的结果就是阻、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的工程师之一的故事，他突破了学和生物工程的极限，并可以说解决了他们的第一大难题。

[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。

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的开放性物理和学问题。

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

此时，定义人群移动的原则更接近学而不是其他任何东西。

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的课。

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

我进入了计算天物理学和恒星形成的磁学领域。

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.

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

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的升有多大，或者一辆车的空气动学性能如何。

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

学是描述液和气动的学科。
