The Tensor Turf War

The Tensor Turf War
The eternal divide between pure mathematicians and physicists captured perfectly! Mathematicians define tensors with rigorous precision—"an element of a tensor algebra"—complete with abstract structures and formal properties (and apparently bodybuilder physiques). Meanwhile, physicists take the pragmatic approach—"something that transforms like a tensor"—focusing only on how it behaves in calculations rather than what it fundamentally is . This is basically the mathematical equivalent of asking "but what is a tensor?" and getting two completely different answers depending on which department you're in. The buffed Doge vs. regular Doge format perfectly captures how mathematicians think their definition is inherently superior while physicists are just trying to get their equations to work before lunch.
