## A classical “deep” simplification involves the use of Minkowski’s metric equation to view special relativity, prior to tackling the formidable obstacles presented by multiple inertial frames.

## This equation precipitated thinking that lead to even deeper simplifications in our understanding of gravity, at the same time extending Pythagoras’ theorem to allow study: (i) of relativistic acceleration with simple algebra, and (ii) of curved spacetime problems with simple calculus.

## Edwin Taylor won the Oerstead medal of the American Association of Physics Teachers, earlier this year, and is now co-authoring a book on Scouting Black Holes with John Wheeler, with hopes for “a second course” in physics directed in part to this end.
