@Jasper10,
The reason Einstein could not relate his theories to the quantum was because he he didn’t understand that the universe operates due to electromechanical processes and absolutely does not operate due to a philosophically biased secular science gravity theory.
He didn’t understand magnetic force “toggling” effect on matter due to SPIN.
Everything vibrates or “toggles” in the universe producing sinusoidal wave forms.Even electrical and magnetic fields.Everything interacts because everything is interconnected.The universe is saturated with push/pull magnetic forces at both the macro and micro levels.This is what holds particles together.
Electromagnetism is the common denominator between the macro and micro therefore.
Natures science and philosophy is different to secular science and philosophy.
PERIOD.
