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

60年代流行的是自旋流体。

The research is in the Journal of Fluid Mechanics.

项研究已在《流体》杂志上发表。

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

如果我们在习流体，它指的是我们解决的练习题数量。

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

一发现已经出现在匹兹堡召开的美国物理会流体会年度会议上。

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

当然，想要制作种动画，我们还需要具有物理知识，懂得动画背后的流体原理。

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

流体是对液体和气体流动的描述。

Next the hydrokinetics, the hydromechanics and the hydrostatics.

接下来的是流体动，流体和流体静。

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

流体是出了名的困难，主要是因为分子等微小物体的运动会变得非常复杂。

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

使用流体，您可以计算出飞机机翼产生了多少升，或者汽车的空气动特性如何。

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

- [Derek] 对于流体，我总是希望你必须保持雷诺数与现实世界现象相同。

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、水或是流体，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，我们还会做大量的流体研究，以发现零重环境下流体的状况。

And so a single scuba diver can go anywhere from the surface to 40 meters, or 120 feet deep, to measure the hydrodynamic signatures that organisms create.

样潜水员可以到达 水下40米以内的任何地方，120英尺深的任何地方，去记录生物体留下的流体的痕迹。

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.

因此，我们所做的工作是将流体与健康和流行病相关的问题结合起来，以更好地了解病原体的传播方式。

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，他突破了流体和生物工程的极限，并可以说解决了他们的第一大难题。
