Superposition principle print that page


In physics and systems theory , the superposition principle [ 1 ] , also known as superposition property , states that, for all linear systems , the net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus

Quantum superposition print that page

the overlap energy of the states is nullified, and the expectation value of an operator (any superposition state) is the expectation value of the operator in the individual states, multiplied by the fraction of the superposition state that is "in" that state. An example of a directly | 2011/9/23 0:45:55

Law of superposition print that page


The law of superposition (or the principle of superposition ) is a key axiom based on observations of natural history that is a foundational principle of sedimentary stratigraphy and so of other geology dependent natural sciences : “ Sedimentary layers are deposited in a time

Principle of original horizontality print that page


large plates of the Earth's crust is the cause of folded strata . As one of Steno's Laws, the Principle of Original Horizontality served well in the nascent days of geological science . However, it is now known that not all sedimentary layers are deposited purely horizontally. For instance

Schrödinger's cat in popular culture print that page


illustrates MacIntyre's science-fiction story "Schrödinger's Cat-Sitter". The cat occupies a quantum superposition relative to the tined object , being simultaneously in front of and behind the object, which itself occupies a quantum superposition because it is simultaneously a square-edged

Uncertainty principle print that page

In quantum mechanics , the Heisenberg uncertainty principle states a fundamental limit on the accuracy with which certain pairs of physical properties of a particle, such as position and momentum , can be simultaneously known. In other words, the more precisely one property is measured, | 2011/10/4 4:46:24

Correspondence principle print that page

In physics , the correspondence principle states that the behavior of systems described by the theory of quantum mechanics (or by the old quantum theory ) reproduces classical physics in the limit of large quantum numbers. The principle was formulated by Niels Bohr in 1920, [ 1 ] though | 2011/4/23 11:08:34

Pauli exclusion principle print that page

The Pauli exclusion principle is the quantum mechanical principle that no two identical fermions (particles with half-integer spin ) may occupy the same quantum state simultaneously. A more rigorous statement is that the total wave function for two identical fermions is anti-symmetric | 2011/8/9 10:34:38
