Why sub-classical physics and quantum physics, can not be unity between the two up?

What do you mean by "sub-classical"?

Sorry, I am a Chinese, English is not so good. I mean about the classical physics "and" quantum physics ", why should distinguish respectively

Why sub-classical physics and quantum physics


With classical physics you cant compute and examine the physics of the too small, at the level of atoms and sub-atomic particles. Classical physics is basically a very good approximation of how the macroscopic worls behaves, but when you examine the microscopic everything is so more complex and sometimes counter-intuitive. Its possible to use quantum physics to calculate macroscopic behavior, but it would imply too many calculations.

Actually, classical physics are special case of quantum mechanics for big masses, big objects and trajectories. In macroscopic world quantum effects are neglectible.
