Quantum mechanics’ is more than just ‘atomic physics.’ The study of matter and energy on the smallest scale is called quantum physics.
The terms quantum physics and quantum mechanics are not the same. The main difference between quantum physics and quantum mechanics is that quantum physics is a branch of science that focuses on quantum mechanics.
Is quantum mechanics a part of physics?
It is important to realize that quantum mechanics is a branch of physics and that the business of physics is to describe and account for the way the world is on both the large and the small scale.
What is the difference between quantum mechanics and modern physics?
The weird behavior of particles in the universe is explained by quantum mechanics. Classical physics failed to explain a number of microphysical phenomena at the end of the 19th century. Quantum mechanics is the branch of physics that studies the motion of atoms. One of the main goals of modern physics is to describe the properties of atoms and molecules. It is the physics that explains what happens.
