Tensors

"In the four-dimensional time-space we consider tensors of different orders. The tensor of order zero is a pure number (scalar), the tensor of the first order is a vector, which has 4 components, the tensor of the second order has 16 components, and so on. If once we have expressed the laws of nature in the form of linear relations between tensors, they will be invariant for all transformations. Thus with the aid of the calculus of tensors Einstein has succeeded in satisfying the postulate of general relativity."

Um, if you say so.

Not exactly what I had in mind. For me a tensor is something that adds a little tension where a little tension is called for. For example, you're wearing black pants, a black jacket, and a pink shirt. No tension at all. But if you are wearing a pair of shoes that feature a shade of pink that clashes ever so slightly with your pink shirt, then those shoes serve as your tensor.

I don't wear ties, but if I did, I would think of the tie as the tensor of my ensemble.

A tensor could also be a musical note added to a chord to give it just the right amount of dissonance.

We need tension. Without it, all would be globs and blobs and utterly boring. But we need to get the level our tension just right! Without tension nothing could be "intense." Art without tension is not artistic.

What we don't need is stress, which is what we get when there is too much tension.

In this photo, the red building serves as the tensor.
