Tensor Phone Cases - iPhone and Android

Description: A beautiful equation, assembling the four equations of Maxwell in a compact unique equation.

Description: The definition of the electromagnetic tensor derived by working in 4 dimensions in Minkowski spacetime.

Description: The Jacobian matrix made out of the different partial derivatives of the components of the function, which is used in solving linear partial differential equations, and other problems in mathematics

Description: The Einstein Field Equations are a useful set of differential equations that describe the behavior of a scalar field in a vacuum. They have been used extensively in the fundamental physics of special relativity, quantum mechanics, and in relativity and cosmology.
