WebHere is a brief history of tensors and tensor products. Tensor comes from the Latin tendere, which means \to stretch." In 1822 Cauchy introduced the Cauchy stress tensor in continuum mechanics, and in 1861 Riemann created the Riemann curvature tensor in geometry, but they did not use those names. In 1884, Gibbs [6, Chap. 3] introduced tensor WebThe dual electromagnetic field Up: Relativity and electromagnetism Previous: Tensors and pseudo-tensors The electromagnetic field tensor Let us now investigate whether we …

In particular, the spin density coincides with the helicity flux density, the true energy density appears in the boost momentum, and so on.
