Right? So, what is a slide rule?

正确的？那么， 什么是计算尺？

Nobody uses a slide rule, unless you go to maybe Oxford in the 1960s.

没有人使用计算尺， 除非你在 1960 年代上过牛津大学。

And the slide rule was just a kind of physical incarnation of that.

计算尺只是它的一种理化身。

I have a fondness for the slide rule as an object.

我很喜欢计算尺体。

Now, what tips would you give people who are looking to run the slide rule over making a new investment?

在， 您会给那些希望在进行新投资使用计算尺的人提供什么建议？

My father graduated with a degree in mathematics, and I remember seeing slide rules around his house.

我父亲毕业获得了数学学位，我记得在他家里看到过计算尺。

The slide rule made calculations a lot faster and less error-prone than using the log charts and pen and paper.

与使用日志图表和笔和纸相比，计算尺使计算速度更快且更不易出错。

For most people, it was the first time they didn't have to do math on paper or use a slide rule.

对于大多数人来说，是他们第一次不必在纸上做数学或使用计算尺。

It's that when you use the slide rule, at a certain point, you're essentially needing to estimate your result.

当您使用计算尺，在某刻，您本质上需要估计您的结果。

And this means that if all you have is a slide rule, you have to simplify it.

意味着如果你只有一把计算尺，你就必须简化它。

The parting in his short gray hair was almost unnaturally straight, and his narrow toothbrush mustache looked as though he trimmed it using a slide rule.

他银色的短发几乎被不自然地梳得笔直，他的短小胡子，像是比着滑尺修剪过的。

And then really the next big innovation is a thing called the " slide rule." The slide rule was a major innovation that came along in the 1600s.

真正的下一重大创新是一种叫做“计算尺”的东西。计算尺是 1600 年代出的一项重大创新。

The guy with blueprints; the guy in a three-piece suit; the guy with a slide rule and calculator; the guy that's going to pave the forest and perhaps destroy whole ecosystems.

些人带着蓝图，穿着三件套西装，随身携带着卷尺和计算器，些人会在森林里修路，甚至可能摧毁整生态系统。

So, the calculator–the thing that we might recognize as a calculator–kind of has to have a different form because the slide rule's form isn't cutting it.

因此，计算器——我们可能认为是计算器的东西——必须有不同的形式，因为计算尺的形式不能满足它的需要。

So, prior to the slide rule, we had to calculate logs using these long charts known as " log tables." So, the basis behind the slide rule were these very, very long books of incredibly accurate logarithmic tables.

因此，在计算尺出之前，我们必须使用些称为“对数表”的长图表来计算对数。所以，计算尺背后的基础是些非常非常长的书，里面有极其精确的对数表。

Fundamentally, if you're going to be doing a lot of calculations with a slide rule, everything has to be linear, by which I mean most equations need to just be multiplications or divisions or just adding some constant number.

从根本上讲，如果您要使用计算尺进行大量计算，那么一切都必须是线性的，我的意思是大多数方程只需是乘法或除法，或者只是添加一些常数。
