我暫時當tensors只係generalised scalars, vectors and matrices.
Zeroth order tensor 係scalar
First order tensor係vector
Second order tensor係兩支first order tensor嘅一個product,係一個matrix

Maths/physics轉econ唔少人(John Nash),econ轉Math/Phy呢,。

讀fluid勁多tensor

以fluid同埋material嚟講可以。再睇Tensor definition: https://mathworld.wolfram.com/Tensor.html
Tensor=mathematical objects that obey certain transformation rules. What’s the difference?
