Tensor

[ Clarification ] Tensors could be written as "scalar" "vector" "matrix" etc.. but "scalar" "vector" "matrix" aren't always tensors. This is because scalar vector matrix are more of mathematical definitions whereas tensor describes a physical quantity. "Tensor" relates to the word "tension". I explained about the tensor for Physics and Engineering students. I mainly tried to relate with General relativity course. Stress tensor, energy-stress tensor and momentum-stress tensor are also explained.
