- So those parts of the metric tensor turn out to be really important.
- Minkowski space, Riemannian geometry, the Ricci tensor, Lorentz symmetry, the Poincare group.
- There's specific the type of MRI that shows connectivity in the brain called GTI diffusion tensor imaging.
- So they can't be tensors, and they're not.
- But, but anyway, I I couldn't wait to do all the tests that we do to look for the length of the tensor.
Examples
-
In this next study, DTI study, this diffusion tensor imaging, it's kind of MRI.
-
The tensor, in turn, can be related directly to components of the Riemann curvature tensor of spacetime generated by the wave.

Etymology
The word tensor also comes from the Latin tendere meaning 'to stretch', which you can see in tension. In math and physics a tensor is a way to describe how things 'stretch' or change when forces act, so a tensor shows the relationships between directions and strength.
