Quantum physics is a branch of science that studies the behavior of matter and the activities that occur inside atoms. It aims to understand the properties and behaviors of the fundamental building blocks of nature.  Quantum physics is the best description of the particles that make up matter and the forces with which they interact. It explains the physical phenomenon by microscopic and atomic approaches and considers the dual behavior of matter.  Quantum physics can lead to apparent paradoxes. For example, in Schrödinger's cat, an uncertain quantum process leaves a cat dead and alive at... Show more
