classical physics vs quantum physics
Why do we say that classical physics is a lot different from quantum physics?
The laws that determine the macroscopic world should be derivable from quantum laws. So in a way the Newtonian or classical laws are basically quantum laws( maybe a bit approximated)
So why differentiate between macroscopic and microscopic world?

All dogs may be animals but not all animals are dogs.
All classical physics is a consequence of quantum - but not all quantum physics can be described classically.
Technically - classical physics is what QM does on average ... so the math is different.
