Quantum mechanics

Quantum mechanics (QM; also known as quantum physics or quantum theory) including quantum field theory, is a fundamental branch of physics concerned with processes involving, for example, atoms and photons. In such processes, said to be quantized, the action has been observed to be only in integer multiples of the Planck constant, a physical quantity that is exceedingly, indeed perhaps ultimately, small. This is utterly inexplicable in classical physics.

Quantum mechanics gradually arose from Max Planck's solution in 1900 to the black-body radiation problem (reported 1859) and Albert Einstein's 1905 paper which offered a quantum-based theory to explain the photoelectric effect (reported 1887). Early quantum theory was profoundly reconceived in the mid-1920s.

The reconceived theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical function, the wave function, provides information about the probability amplitude of position, momentum, and other physical properties of a particle.

Quantum

In physics, a quantum (plural: quanta) is the minimum amount of any physical entity involved in an interaction. Behind this, one finds the fundamental notion that a physical property may be "quantized," referred to as "the hypothesis of quantization". This means that the magnitude can take on only certain discrete values.

A photon is a single quantum of (visible) light as well as all other forms of electromagnetic radiation and can be referred to as a "light quantum". The energy of an electron bound to an atom is quantized, which results in the stability of atoms, and hence of matter in general.

As incorporated into the theory of quantum mechanics, this is regarded by physicists as part of the fundamental framework for understanding and describing nature.

Etymology and discovery

The word "quantum" comes from the Latin "quantus", meaning "how much". "Quanta", short for "quanta of electricity" (electrons) was used in a 1902 article on the photoelectric effect by Philipp Lenard, who credited Hermann von Helmholtz for using the word in the area of electricity. However, the word quantum in general was well known before 1900. It was often used by physicians, such as in the term quantum satis. Both Helmholtz and Julius von Mayer were physicians as well as physicists. Helmholtz used "quantum" with reference to heat in his article on Mayer's work, and indeed, the word "quantum" can be found in the formulation of the first law of thermodynamics by Mayer in his letter dated July 24, 1841. Max Planck used "quanta" to mean "quanta of matter and electricity", gas, and heat. In 1905, in response to Planck's work and the experimental work of Lenard (who explained his results by using the term "quanta of electricity"), Albert Einstein suggested that radiation existed in spatially localized packets which he called "quanta of light" ("Lichtquanta").

Amit

Amit is a common male name, in India, Nepal and Israel.

In Nepali, Sanskrit, Hindi, and Bengali, Amit (Hindi: अमित, Bengali: অমিত) means infinite or immeasurable or limitless or boundless. It is the wordstem root of the Amitabha Buddha and one of the 108 names of Hindu God Shri Ganesha. It also means an eternal friend of everyone in Hindi, Nepali and Sanskrit

In Hebrew, Amit (Hebrew: עמית‎) means colleague, friend. The word appears in the Bible in a context vaguely suggesting such a meaning. However, Even-Shoshan dictionary suggests a Roman source (esp. French: Ami). Though traditionally a common male name, it is being increasingly used as a female name in Israel. Nevertheless, it is still among most popular names given to Jewish boys in Israel.

Coast to Coast AM is a North American (United States and Canada) late-night radio talk show that deals with a variety of topics. Most frequently the topics relate to either the paranormal or conspiracy theories. The program is distributed by Premiere Networks, both as part of its talk network and separately as a syndicated program. The program now airs seven nights a week 1:00 a.m. – 5:00 a.m. Eastern Time Zone.

Created and originally hosted by Art Bell, the program is now hosted on most nights by George Noory. According to estimates by Talkers Magazine, Coast to Coast AM has a cume (cumulative weekly audience) of around 2.75 million unique listeners (listening for at least five minutes), making it the most listened-to program in its time slot. Today, the program is heard on more than 600 stations in the U.S., Canada, Australia and Guam.
