No society could improve, Fourier believed, until women's lot improved.

叶认为，除非女性的命运得以改善，否则整个社会难以得以发展。

It was radical when Fourier wrote it in 1808.

但1808年，叶写下的这句话却显得尤为激进。

And it mixes that with deep neural networks, and hence, this is called Deep Fourier-based super-resolution.

它将叶变换与深度神经网络结合，因此被称为基于深度叶的超分率。

Fourier was wounded, so he demanded a second duel.

叶受伤了，所以他要求进行第二次决斗。

" It's like grading high-school students on middle-school tests, " says Dr Fourrier.

“这就像是根据初中的考试成绩来给高中生评分一样，”叶博士说。

Here's an example seismometer signal and its Fourier transform.

这是一个地震仪信号及其叶变换的示例。

This whole plot is what I'll call the " Almost Fourier Transform" of the original signal.

整个图就是我所说的原信号的“近叶变换”。

But, says Dr Fourrier, benchmark scores " should be taken with a pinch of salt" .

但是，叶博士表示，基准分数“应该持怀疑态度”。

They also have to do a Fourier analysis, decompose that, do a power spectrum, filtration, windows.

他们还需要进行叶分析，分解信号，进行功率谱分析，实施滤波处理，并应用窗口技术。

This conversion from waveform to frequencies is done with a very cool algorithm called a Fast Fourier Transform.

这个从波形到频率的转换是通过一个非常酷的算法——快速叶变换来完成的。

The fundamentals of the science around the greenhouse effect date back to Joseph Fourier some 200 years ago.

温室效应的科学基础可追溯到约200年前的约瑟夫·叶。

And so there's definitely a lot of love and crossover between Wolf and- Her name was Dr. Fourier.

因此，狼和——她的名字是叶博士——之间肯定有很多爱和交集。

There are some elegant ways to understand how Fourier transforms work, shout out to the awesome video by 3Blue1Brown.

有一些优雅的方法可以理解叶变换的工作原理，请观 3Blue1Brown 的精彩视频。

The Fourier transform is just the integral part of this.

叶变换就是这个积分部分。

Well, then the discrete Fourier transform will have eight frequency bins.

那么离散叶变换将有八个频率仓。

And now, there is only one final distinction to point out between this and the actual, honest-to-goodness Fourier transform.

而现在，只需要指出这一点与真正的、货真价实的叶变换之间的最后一个区别。

And you have the discreet Fourier transform of this really simple signal.

你可以对这个非常简单的信号进行离散叶变换。

Now this process works fine in principle and you could use it to calculate all discrete Fourier transforms.

现在这个过程原则上工作得很好，您可以用它来计算所有离散叶变换。

Garwin observed Tukey doodling throughout but what he was actually doing was working on discreet Fourier transforms.

加文自始至终都在观察图基的涂鸦，但他实际上所做的是离散叶变换。
