Looks at a very interesting intersection of science and politics -- how the animosity of Germans, even by scientisits, during and after World War 1 had to be overcome in order for relativity (proposed by world citizen Einstein) had to be disseminated as a theory, and then proven (by a team led by an English scientist/pacifist. Fascinating to think about the lack of objectivity when it comes to science (think: the climate catastrophe).
That it was written and read by my grandson's godfather made it even interesting. Still can't say I understand relativity, though.
