Or the slide rule, for assisting with multiplication and division.

或者计算尺，用于辅助乘法和除法。

Oh, and the phones, of course, mechanical typewriters and slide rules then, no fancy laptops and cell phones.

还有电话，当然，还有机械打字机和计算尺，没有花哨笔记本电脑和手机。

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。

Right? So, what is a slide rule?

正确？那么， 什么计算尺？

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

计算尺只一种物理化身。

But this was a manual for how to use this slide rule, which is enormously important.

但这本手册关于何使用计算尺，其重要性言而。

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

当您使用计算尺时，在某个时刻，您本质上需要估计您结果。

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

我很喜欢计算尺这个物体。

In this book, he talks about a compass, which is not a magnetic compass, but an actual slide rule.

在这本书中，他谈到了一个指南针，这个指南针并非磁性指南针，而一个真正计算尺。

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

我父亲毕业时获得了数学学位，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易出错。

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

这意味着果你只有一把计算尺，你就必须简化。

Then he brought in some books on mathematics and physics and other things, and a bunch of slide rules, calculators, and junk.

然后他拿来了一些关于数学和物理及其他学科书籍，还有一堆计算尺、计算器和其他杂物。

When I visited my dad's house, I would marvel at the slide rules that he had in his junk drawer.

当我参观父亲房子时，我会对他垃圾抽屉里计算尺感到惊讶。

It is a tale that starts with a 42,000-year-old tally stick found in South Africa and moves through finger-counting systems to the abacus and the slide-rule.

这个故事从在南非发现一根有 42,000 年历史计数棒开始，通过手指计数系统发展到算盘和计算尺。

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——我们可能认计算器东西——必须有同形式，因计算尺形式能满足需要。

In other words, you can model things with great predictability and accuracy using supercomputers that you couldn't possibly do sitting with a slide rule or sitting with Traditional mathematics.

换句话说，你可以使用超级计算机以极高预测性和准确性来建模，这你用计算尺或传统数学方法根本无法做到。

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.

真正下一个重大创新一种叫做“计算尺”东西。计算尺 1600 年代出现一项重大创新。

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，果您要使用计算尺进行大量计算，那么一切都必须线性，我意思大多数方程只需乘法或除法，或者只添加一些常数。

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，在计算尺出现之前，我们必须使用这些称“对数表”长图表来计算对数。所以，计算尺背后基础这些非常非常长书，里面有极其精确对数表。
