can anyone tell me the difference between classical mechanics and quantum mechanics??

Er... no. A key conclusion of QM is that waves and particles are just different sides of the same coin. Mathematically, Schrodinger wave equations are ultimately equivalent to quantum particle equations. The schrodinger equation gets most limelight because it is generally considered as easier, and making more sense.Quantum is all about waves, the dynamics of all things is determined by waves.
Classical mechanics is a theory that describes the motion of macroscopic objects in the world we experience, while quantum mechanics is a theory that describes the behavior of particles at the atomic and subatomic level.
Quantum mechanics is considered to be the more fundamental theory, as all classical mechanics principles can be derived from it. However, classical mechanics is still a useful and accurate theory for describing the behavior of macroscopic objects.
The uncertainty principle states that it is impossible to know both the exact position and momentum of a particle at the same time. This is due to the probabilistic nature of quantum mechanics, where the location of a particle can only be described in terms of a probability distribution.
Quantum mechanics describes particles as having wave-like properties, such as being able to exist in multiple states simultaneously. This allows for phenomena such as superposition and entanglement, which have no classical counterpart.
Mathematics is essential in both classical and quantum mechanics. Classical mechanics uses mathematical equations to describe the motion of objects, while quantum mechanics relies heavily on mathematical concepts such as wave functions and operators to describe the behavior of particles.
