Indeed, Samkhya-Yoga is not identical to quantum physics, because they are based on a completely different approach. Quantum physics is based on measurement and analysis of reality by doing physical experiments and then formally explaining that using mathematics. Quantum physics is also a more deeper and vigorous study into matter. Samkhya, on the other hand is a experiential based analysis of reality which is then rationally explained using reasoning.
Samkhya-Yoga rather than beginning by analysing matter to see what the world is made of, begin by analyzing experience to show what our world of experience is made of. If now we look at the Samkhya categories we can see why they enumerate these categories as such.
Observation shows us that all information comes to us via our senses, of which there are 5 major senses: ears, skin, eyes, tongue and nose. They each receive a particular category of data: ears receive sound, skin receives touch, eyes receive colour, tongue receives taste and nose receives smell. Thus the essential sensory elements are known tanmatras. The source from which the data is being received are gross and tangible physical elements and are known as the bhuttas.
Then analysis will show that the bhutas have specific properties. Earth, received by the nose as smell has all 5 properties of mass and weight, liquidity, form, movement and vibration. Water, received by the tongue as taste has 4 properties of liquidity, form, movement, vibration. Light, received by the eyes as colour, has 3 properties of form, movement and vibration. Wind, received by the skin as touch has has 2 properties of movement and vibration. Ether, received by the ears as sound waves, only has 1 property of vibration.
Thus the sequence of how the elements come into being is inferred in this order from most subtle to gross: sound waves, winds/forces, light, fluidity and solid matter. This is of course near identical to how modern physics understands how matter comes into being. It begins as a wave, then next up we have fundamental forces like gravity, then photons, then electrons etc and finally atoms. It is interesting to note even in Samkhya matter begins as a wave before it becomes a particle and attains mass. Again, this cannot be a coincidence.
The next categories Samkhya deals with are mental categories: manas, ahamkara and intellect, which are collectively known as the instrument of cognition and inner instrument(anthakarana) Samkhya observes there is a faculty within us which processes data, makes judgements and personalizes the world and hence posit the existence of mind. It also posits the existence of a subtle body as the framework that holds these entities.
Then using inference Samkhya concludes that the mind and physical matter are both possessed of the properties of the gunas i.e., they are the same continuum of matter. It thus declares that it is the mental which produces the physical or the physical is just a more gross manifestation of the mental. The mental and the physical are in an interactive relationship.
Hence Samkhya declares there are three levels or dimensions of matter: There is the physical consisting of the physical elements; the subtle consisting of the subtle elements, senses and mind. The final dimension of matter, the causal, is inferred through several arguments that there must be a fundamental, undifferentiated, imperceptible state where the gunas are vibrating, which is producing all other dimensions of matter.
In the end though Samkhya and Modern physics take an entirely different approach of study of reality, they arrive surprisingly at similar conclusions of how reality is constituted. Thus this goes to show that in order to study reality the yogi is just as much equipped as a physicist in working it all out.
