The idea that solar sails have a principle of operation includes
both notions of solar flux after stellar pulsation, and as well
as what sort of results from Casimir, where Casimir force, and
Casimir effect, is cataloged under effects and forces when
they're "fictitious", in a world of "hidden" variables, what
as well are as simply complementary and supplementary in the
wider dialectic, vis-a-vis the ultraviolet catastrophe,
electron physics, and ignorance about notions like
the "second spectrum" of light and these kinds of things.

In 1846 Faraday announced new principles and effects about daily.
Many of these of course still exist as "empirical" or outside
the model of "most severe abstraction".
