Quantum mechanics is used to explain the behavior of objects the size of an atom or smaller. Without QM, we could not understand how transistors operate, much less how to build them. No transistors, no high speed electronics, no personal computers, no internet, no 'Answers.com'.

∙ 13y agoThe theory of quantum mechanics is used to explain the structure of atoms, atomic nuclei, and molecules; the behaviour of subatomic particles; the nature of chemical bonds ; the properties of crystalline solids ; nuclear energy; and the forces that stabilize collapsed stars. It also led directly to the development of the laser, the electron microscope, and the transistor.

Also, pretty much everything that ever happens ever happens because of quantum mechanics, as it is the study of how EVERYTHING works fundamentally, although that could and did happen even if we didn't know it.

What is dynamical quantities in quantum mechanics?
One of the quantities used to describe a system in classical mechanics, such as the coordinates of a particle, thecomponents of its velocity, the momentum, or functions of these quantities.
How does the atomic model you used today differ from Bohr model?
The modern atomic model is based on quantum mechanics.
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.
What is classical particle?
Classical physics refers to the branch of Physics whereby energy and matter are two very different concepts. It is usually based on the theory of electromagnetic radiation and the laws of motion.
Why it is said relativistic quantum mechanics?
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler. Physics students typically study regular quantum mechanics before moving on to quantum field theory.
Who developed the quantum theory of the nuclear atom and used the observations of albert Einstein to formulate it?
Quantum Mechanics was invented by Max Plank - and Einstein had nothing to do with it, in fact Einstein was uncomfortable with Quantum Mechanics for the entirety of his career.
What is a bidoublet?
A bidoublet is a term used in quantum mechanics for a binary doublet.
What is quantum computing used for?
The Quantum computer is used for Quantum mechanics. A regular computer or laptop has restrictions due to physics but a Quantum computer performs faster with being able to be in more states at once.
Where is quantum physics used in the real world?
I'm guessing you are asking why we do not see quantum behaviour in the normal world? Well if it is then because of the a effect called decoherence (the interference of air and other mediums) that wipe out quantum behaviour in macroscopic objects

Quantum mechanics can be used to calculate the probability of an electron's what at any given time?
An electron's location or momentum, but not both.

Which System of mathematical equations is used to describe behavior of small particles traveling at velocities near speed of light?
Schrödinger's equations, I believe
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.
