To answer, we first need to understand scalars.

要回答这个问题，我们要解标。

You can either use forces and vectors or you can use energies and scalars.

您既可以使用力和矢，也可以使用能和标。

It's a scalar field, like we think caused inflation, like dark energy could be.

这是一个标场，就像我们认为引发膨胀的那样，类似于暗能可能的形态。

And we were to plot all of the scalar quantities.

我们要绘制所有的标值。

Where are all of the scalar quantities equal.

在哪里所有的标都相等。

That's a scalar, one of the five scalars that they use.

那是一个标，他们是使用的五个标之一。

And now let's  begin the unit 1 review in earnest with vectors and scalars.

现在让我们从向和标开始认真复习第一单元。

And Bobby, please give me some examples of scalars in physics.

鲍比, 请给我举一些中标的例子。

It turns out that scalars also share this coordinate invariance property.

原来标也具有这种坐标不变性。

That's what's called the scalar curvature.

那被称为标曲率。

Remember how I said that linear algebra revolves around vector edition and scalar multiplication?

还记得我说过线性代数围绕着向编辑和标乘法吗？

How would you take those two scalar fields and then bring them together?

你怎么把这两个标场结合在一起？

So a scalar field is, there's, is the temperature the same in every part of the room?

所以，标场是指，房间各处的温度是否相同？

So when you say everything is curved, that R is the scalar curvature of Einstein's pseudo-Romanian metric.

所以当你说到一切都是弯曲的，那个R是爱因斯坦伪罗马尼亚度的标曲率。

Anyway, so there could be a scalar field in the universe that is the dark energy.

无论如何，宇宙中可能存在一种标场，它就是暗能。

But dark energy could also take the form of a scalar field.

但暗能也可能以标场的形式存在。

Now scalar quantities are just a magnitude.

现在标仅仅是大小。

Like if, you know, let's go back to our kind of second grade world of just scalars.

就像，你知道的，让我们回到我们那种只有标的二年级世界。

This is considered to be a scalar quantity.

这被认为是一个标。

And to do that lots of times you will have to add different scalar quantities.

为了做到这一点很多次，你将不得不添加不同的标。
