Quantum mechanics

Quantum mechanics is a branch of physics which deals with physical phenomena at microscopic scales, where the action is on the order of the Planck constant. Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. In advanced topics of quantum mechanics, some of these behaviors are macroscopic and emerge at only extreme energies or temperatures. The name quantum mechanics derives from the observation that some physical quantities can change only in discrete amounts, and not in a continuous way. For example, the angular momentum of an electron bound to an atom or molecule is quantized. In the context of quantum mechanics, the wave–particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons, and other atomic-scale objects. The mathematical formulations of quantum mechanics are abstract. A mathematical function known as the wavefunction provides information about the probability amplitude of position, momentum, and other physical properties of a particle. Mathematical manipulations of the wavefunction usually involve the bra-ket notation, which requires an understanding of complex numbers and linear functionals. The wavefunction treats the object as a quantum harmonic oscillator, and the mathematics is akin to that describing acoustic resonance. Many of the results of quantum mechanics are not easily visualized in terms of classical mechanics—for instance, the ground state in a quantum mechanical model is a non-zero energy state that is the lowest permitted energy state of a system, as opposed to a more "traditional" system that is thought of as simply being at rest, with zero kinetic energy. Instead of a traditional static, unchanging zero state, quantum mechanics allows for far more dynamic, chaotic possibilities, according to John Wheeler.

### Sample Sentences & Example Usage

Relativity keeps anything from happening at once.

**Quantum mechanics**keeps everything from really happening at all.**Quantum mechanics**is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us closer to the secret of the 'Old One.' I, at any rate, am convinced that He is not playing at dice.Schrodinger's Cat is a classic example of Paradox, in my view. In actuality, it was a Gedankenexperiment or a Thought Experiment, created by Austrian Physicist Erwin Schrodinger in 1935. Not many folks are probably aware that Schrodinger himself called that experiment “a ridiculous case.” Here’s the "Schrodinger's Cat" in Schrodinger's own words: “A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): In a Geiger Counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none. If it (i.e. decay) happens, the Geiger Counter discharges and through a relay releases a hammer that shatters a small flask of Hydrogen Cyanide. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has (undergone) radioactive decay.” So you see, the cat's life or death truly depends on the formation of a subatomic alpha particle that triggers off the avalanche of electrons in the Geiger Counter. There is an equal probability that it may not happen, and hence the cat should remain both alive and dead per Copenhagen interpretation of

**quantum mechanics.**Philosophically speaking, Human Life is full of paradoxes, and we often find that the uncertainties therein bear a startling resemblance with Schrodinger's Cat experiment. The total randomness of events that shape our human lives, and determinedly control the outcome (i.e. future) can be extremely perplexing and equally thought-provoking as Schrodinger's Cat experiment....a pre-written and pre-destined Reductio ad absurdum perhaps!
