To answer, we first need to understand scalars.

回答这个问题，我们首先需理解标。

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那样，类似于暗能可能形态。

And we were to plot all of the scalar quantities.

我们所有标。

Where are all of the scalar quantities equal.

在哪里所有标都相等。

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

那是一个标，他们是使用五个标之一。

But one of the problems is, okay, what do I do with a Python scaler?

但是一个问题在于，好吧，我该怎么使用一个 Python 标呢？

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, 请给我举一些物理学中标例子。

And what are vectors? Scalars? And what does this mean?

什么是向？标？这是什么意思？

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。

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，那个R是爱因斯坦伪罗马尼亚度标曲率。

Which two dimensional vectors can you reach by altering the choices of scalers?

通过改变标选择可以得到哪些二维向？

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，让我们回到我们那种只有标二年级世界。
