For 10 points, name this physicist who lends his name the force experienced by a charged particle in electric and magnetic fields.
Pseudo-Riemannian manifolds with metric signature one comma n-minus-one are named after this physicist. He also names the subgroup of the Poincaré (pwann-kah-RAY) group consisting of isometries that leave the origin unchanged. This physicist names a quantity equal to the hyperbolic cosine of rapidity. In a set of equations named for him, x-prime is equal to his namesake factor times the quantity x-minus-vt. That namesake factor is equal to one over the square root of one minus beta-squared. He names the coordinate transformations between inertial reference frames with constant relative velocity that form the mathematical foundation of special relativity. For 10 points, name this physicist who lends his name the force experienced by a charged particle in electric and magnetic fields.
