3 Mar 2020: 1.3 Time-independence. Definition. A spacetime is stationary if it admits a Killing vector field ka whichis everywhere timelike: gabk. ... akb < 0. We can choose coordinates as follows. Pick a hypersurface Σ nowhere tangentto ka and introduce

6 Jul 2020: Cobalt yielded an intrinsic rema-nent magnetization of $ 500 kA/m. Other magnetic materials, such asparamagnetic iron oxide, could be utilized with a stronger magneticfield.

8 Nov 2020: 2. Yang-Mills Theory. Pure electromagnetism is a free theory of a massless spin 1 field. We can ask: is it. possible to construct an interacting theory of spin 1 fields? The answer is yes, and the. resulting theory is known as Yang-Mills. The
