Actions and reactions at the quantum level can appear to violate barriers such as the speed of light and/or to occur without a logical relationship between cause and effect. The first is the nature of observed cause and effect in quantum-level interactions. Two aspects of quantum physics are often cited when discussing God or religion. The value of quantum mechanics lies in explaining these tinier transactions, which is useful in theoretical physics and high-level design, but practically meaningless to the average person’s daily experience. Thus, large-scale systems are, in fact, well-defined and absolute and can be predicted with accuracy. However, as a system includes more and more interactions, the probability of some extreme result lessens. Part of the difference between classical and quantum physics is that quantum-level interactions occur according to a probability curve, not a well-defined, absolute cause-and-effect response. In common experience, quantum physics rarely makes a noticeable impact. As models go, however, it is a relatively recent one, having only been accepted by the general scientific community for the past one hundred years or so. Like most other physical theories, quantum physics was developed over many decades through the work of many different scientists. Quantum mechanics also shows that, at these tiny distances, cause-and-effect relationships work according to probabilities rather than determined, specific results. The theories of quantum physics help explain why changes in physical objects at nanoscopic scales only occur in discrete amounts, known as quanta, as well as why these objects appear to act as both waves and particles.

Merely expressing what occurs at the quantum level sometimes requires an exceptional grasp of mathematics and physics. That is, it does not follow the same flow of cause and effect we see at larger scales. Not only does quantum mechanics involve higher-level physics, but much of what happens at the quantum level is counterintuitive. Even more than other specialized fields within the sciences, it is extraordinarily difficult to explain quantum theories in layman’s terms.

Quantum physics, also known as quantum mechanics, is an application of mathematics used to describe the behavior of matter and energy at an unimaginably tiny scale.
