Einstein's view; “For the time being, we have to admit that we do not possess any general theoretical basis for physics, which can be regarded as its logical foundation.” 1940 ('Science') corresponds to Karl Poppers views on poor foundational solidity in science,1 to Russell's 'Turtles all the way down' and 'piled' foundations of structures on boggy ground relying on local consistency, friction and inertia. We argue that 'fundamental' is relative not absolute within reductionist hierarchies and may be infinitely recursive. However 'condensation' of massive particle pairs with discrete rotations may occupy a non-arbitrary position in a sequence with no known smallest possible scale. We identify that at it's ridiculously simplest just relative motion may produce & characterise a ground state of matter and provide a detectable foundational mechanism, pehaps valid at all gauges. Most solutions in science seem simple and obvious once discovered. We explore whether a most fundamental cause may exist, also simpler than assumed. Relative motion in viscous fluids produce paired vortices at all known scales. Additional motions and interactions then build increasingly complex 'particulate' momenta. We test the simplest as a candidate for 'most fundamental' using a Reduction by functionalization variant of the severest Nagalian reductionism test; the unification of established theories. The two 'pillars' of science, Relativity and Quantum Mechanics, often seen as fundamental, may share a single derivation, perhaps even the most ridiculously simple one. Using plain English we test this proposition analyzing outcomes of interactions between one of the simplest motions spherical rotation. Surprising results close to with Einstein, Bell & Von Neumann's ideas are found and tested.
