Introduction — To Vector And Tensor Analysis

A grid or "matrix" of numbers (Stress, Conductivity). It describes how multiple directions interact.

The "magic" of tensor analysis is that tensors follow strict . If you know the components of a tensor in one coordinate system (like standard Introduction to Vector and Tensor Analysis

A list of numbers (Velocity, Force). It has one direction. A grid or "matrix" of numbers (Stress, Conductivity)

This is why Einstein used tensors for . Gravity isn't just a force pulling down; it is the curvature of the "metric tensor" of space itself. Because the laws of physics shouldn't change just because you changed your map, tensors are the only way to write those laws. 4.
