what is quantum mechanics?

Answer 1

Quantum mechanics is a fundamental branch of theoretical physics that supersedes classical mechanics at the atomic and subatomic levels. It provides the underlying mathematical framework for many fields of physics and chemistry, including condensed matter physics, atomic physics, molecular physics, computational chemistry, quantum chemistry, particle physics, and nuclear physics. Quantum mechanics is a subset of quantum field theory and quantum physics in general, which, along with general relativity, is one of the pillars of modern physics.

The term quantum (Latin, "how much") refers to discrete units that the theory assigns to certain physical quantities, such as the energy of an atom at rest (see Figure 1, at right). The discovery that waves could be measured in particle-like small packets of energy called quanta led to the branch of physics that deals with atomic and subatomic systems which we today call Quantum Mechanics. The foundations of quantum mechanics were established during the first half of the 20th century by Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Max Born, John von Neumann, Paul Dirac, Wolfgang Pauli and others. Some fundamental aspects of the theory are still actively studied.

Answer 3

Completely Awesome!! Quantum mechanics, is the inner workings of things at the quantum level.

Answer 4

The branch of physics that deals with the behavior of matter at the level of the atom, the nucleus, and the elementary particle. At this level, energy, mass, momentum, and other quantities do not vary continuously, as they do in the large-scale world, but come in discrete units, or quanta.
It explained the structure of atoms, atomic nuclei (see nucleus), and molecules; the behaviour of subatomic particles; the nature of chemical bonds (see bonding); the properties of crystalline solids (see crystal); 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.

Answer 5

hi Nuff; i for my section sense, with truthfully no clinical evidence, that each and each determination we make on a daily basis provides an probability for yet another ( or parallel universe). I join the Robert A. Heinlein theory, in all likelihood until eventually now a while yet, an incredible fiction author. attempt "The type of The Beast" or "Stranger In a wierd Land"good gentle exciting reads. yet time is a severe subject, and one i'm afraid I relatively have very fastened notions upon. As i've got self assurance God created it,and holds it until eventually, as you need to assert the time is sweet, and guy ought to circulate forward in basic terms, residing each and each 2nd to the fullest, as there isn't any going lower back. "The previous is historic previous, the destiny a secret, we are able to in basic terms stay interior the now." yet to punch a hollow into yet another universe, will in all likelihood happen sometime, what happens next? nicely which would be an entire different universe lower back. LOL have exciting with this one! Bob

Answer 6

as quantum is the light energy ,quantum mechanics deals withthe mechanism of light energy.

Answer 7

Quantum mechanics is branch of chemistry and physics.It cover both subject. It is depend on angular velocity of molecular and time. the study of Q.M is micro level and theoritical mostly.

Answer 8

quantum mechanics is a branch of physics that deals with the existence of atoms both as waves & as particles ;and that waves behave both as particles and as waves!!!!!! UNBELIEVABLE???
ask the great Einstein himself who proposed this theorem.........

Answer 9

It is a topic in Physics, usually tought in A-level physics. It's very hard though.

Answer 10

divya it's the naming of shells or orbitals present inside a atom
