Is quantum mechanics a set of fields or is it just a lone branch of mechanics?
121314151617
Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.

What is the difference between quantum mechanics and quantum physics?
Quantum Mechanics is a branch of physics describing the behavior of energy and matter at the atomic and subatomic scales. It explains it itself and Quantum Physics is the same deal. They're just two different ways in saying it.
Is there any evidence against the theory of quantum cosmology?
Quantum cosmology is a field attempting to study the effect of quantum mechanics on the formation of the universe, especially just after the Big Bang. Despite many attempts, such as the Wheeler-deWitt equation this area of interest has yet to be fruitful. Quantum cosmology is a branch of quantum gravity.
Where on WikiAnswers are the questions and answers on quantum mechanics?
Quantum mechanics questions are generally in the Quantum Mechanics or Physics categories. Unfortunately, though, people mis-categorize lots of their questions. To access these topics, click on the categories in blue, just under your question.
What is quantum physics's impact on the environment?
Quantum mechanics has no effect on the environment it just describes how the environment behaves
What you need to study the quantum mechanics?
Quantum mechanics studies the movement and interaction of subatomic particles, like electrons, nucleons, quarks, etc.
Is quantum mechanics valid only for very small particles like atoms only?
Quantum Mechanics is valid for nearly everything (So far) it's just that the effects of it are only seen in microscopic scales like individual particles.
What happens in the quantum cafe?
The quantum cafe is used by Brain Greene in his book The Elegant Universe to illustrate the weirdness of quantum mechanics. It is also featured in the NOVA documentary with the same name based on his book. A lot of things happen in the cafe, people and objects change in shape, objects teleport around, you order one drink but you get another. As Brain himself remarks you are never sure what you will get when you order something. Since this is just an illustration it is not meant to be a literal description of quantum mechanics. Most of the things in the quantum cafe can be related to the Uncertainty Principle of quantum mechanics.
Why was quantum mechanics invented?
Quantum Mechanics is one of the three branches of Modern Physics, being the other two, Classical Mechanics and Relativist Mechanics. Quantum Mechanics is needed to learn the intimate behavior of the smallest particles existent: subatomic particles. It deals with the interaction amongst, the forms of energy they receive and deliver, and the way they emit energy, a way done in packets, or quanta, also called photons. Quantum Mechanics is one of the base knowledges for the design of modern electronics.
Does the string theory bridge the gap between Einstein's theory of relativity and quantum mechanics?
No, string theory is an attempt to bridge the gap between EVERYTHING, not just relativity and quantum, into one fundamental theory.
Why do electron contunuouslty move?
If you mean move around in "orbit" around the nucleus ...They don't. In quantum mechanics, forget everything you know from everyday experience about how objects behave, because quantum mechanics is WEIRD. One of my teachers once told me "nobody ever really understands quantum mechanics, they just get used to it." There's a fair amount of truth in that statement. Trying to picture it in your mind will only get you so far; at a certain point you just need to do the math and trust what it says even if it doesn't make any sense.
What is quantum mechanics effects?
Quantum mechanics explains the spectrum of glowing bodies, the photo-electric effect, hydrogen emission lines, electron interference patterns -- and just stuff found prior to 1925. QM effects form the basis of all electronics, including the computer on which you are using to ask this question.
Do elecrons move in a circular path?
Well according to quantum mechanics they do not - owing to the uncertainty principle. So instead they just "fuzz" around the nucleus of the atom
