What is QM? Learn About It Now

• bayan
In summary, QM, or quantum mechanics, is a branch of physics that studies the behavior of matter and energy at a very small scale, such as atoms and subatomic particles. It explains how these particles interact and how they can exist in multiple states or locations at the same time. QM is a fundamental theory that has revolutionized our understanding of the universe and has led to the development of many technologies, including transistors and lasers. It is a complex and abstract concept, but its principles have been successfully applied in various fields, including chemistry, biology, and engineering. Understanding QM is crucial for further advancements in science and technology.

I am not reall familiar with QM, although I may have used some of it's formula's before, But I have no Idea of what QM is. Can some one give a link where I can find some summerised description or something please.

Or just try to explain it to me.

Try wikipedia or something like that. It'll give you a general idea of what's involved a provide some ideas on where to look if you want to know more.

Ok I can try this one, though it may be to basic of an answer. Anyhow, quantum mechanics is the theory that energy is stored in small quanta or packets rather than a large continuous stream. It is to say certain atomic events only occur given they reach certain energy levels. Take electrons in a atom for example, in order to boost an electron to a higher energy level, that electron must absorb a discreet amount of energy. Any less and it will not make the transition. Thats about as basic as I can get right now. Also not that theories in quantum mechanics must revert back to classical views as objects approach marcoscopic levels. Thats to say the theories can be applied to large objects, but the solutions become so precise and complicated that they revert back to classical views such such as Newtonian mechanics.

1. What is QM?

Quantum mechanics (QM) is the branch of physics that studies the behavior of particles at a microscopic level, such as atoms and subatomic particles. It describes how these particles interact with each other and with energy, and provides a framework for understanding the fundamental laws of nature.

2. How does QM differ from classical mechanics?

Classical mechanics is the branch of physics that studies the behavior of objects at a macroscopic level, such as how a ball moves when it is thrown. QM differs in that it takes into account the wave-like behavior of particles at the microscopic level and does not follow the same rules as classical mechanics.

3. What are some practical applications of QM?

QM has numerous practical applications in fields such as electronics, chemistry, and materials science. Some examples include transistors, lasers, and magnetic resonance imaging (MRI) technology.

4. How did QM come about?

QM developed in the early 20th century as physicists began to study phenomena at the atomic level and realized that classical mechanics could not fully explain their observations. Scientists such as Max Planck, Albert Einstein, and Niels Bohr made significant contributions to the development of QM.

5. Is QM a complete theory of the universe?

No, QM is not considered a complete theory as it does not fully explain all aspects of the universe, such as gravity. It also conflicts with the principles of general relativity, which describes the behavior of objects on a large scale. There is ongoing research and debate in the scientific community to try and reconcile these theories and develop a more complete understanding of the universe.
