Physicists and acoustic engineers tend to discuss sound pressure levels in terms of frequencies, partly because this is how our ears interpret sound.

Physicists struggled with this problem, which later became known as the ultraviolet catastrophe, unsuccessfully for many years.

Physicists began to understand the concept of a black hole, and to identify quasars as one of these objects ' astrophysical manifestations.

Physicists assumed, morever, that like mechanical waves, light waves required a medium for propagation, and thus required Huygens's idea of an aether " gas " permeating all space.

Physicists also call one-dimensional orthogonal projectors pure states and other density operators mixed states.

Physicists can measure when they can find the operations by which they may meet the necessary criteria ; psychologists have but to do the same.

Physicists often use the way each interpretation deals with Schrödinger's cat as a way of illustrating and comparing the particular features, strengths, and weaknesses of each interpretation.

Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call " vacuum " or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space.

) Physicists have not found any natural process which would be predicted to form a wormhole naturally in the context of general relativity, although the quantum foam hypothesis is sometimes used to suggest that tiny wormholes might appear and disappear spontaneously at the Planck scale, and stable versions of such wormholes have been suggested as dark matter candidates.

Physicists were initially uncertain of the nature of X-rays, although it was soon suspected ( correctly ) that they were waves of electromagnetic radiation, in other words, another form of light.

* Physicists develop M-theory.

Physicists have long been aware that there are solutions to the theory of general relativity which contain closed timelike curves, or CTCs — see for example the Gödel metric.

Physicists showed in the 1920s that in gas at extremely low densities, electrons can populate excited metastable energy levels in atoms and ions which at higher densities are rapidly de-excited by collisions.

Physicists have testified at United States Congressional hearings, however, that weapons with yields of 10 kilotons ( 42 TJ ) or less can produce a very large EMP.

Physicists who study the electrical properties of matter at the microscopic level use a closely related and more general vector equation, sometimes also referred to as Ohm's law, having variables that are closely related to the V, I, and R scalar variables of Ohm's law, but which are each functions of position within the conductor.

Physicists from across Europe ( and sometimes further abroad ) often visited the Institute to confer with Bohr on new theories and discoveries.

Physicists coordinate the beams so that they collide at the centers of two 5, 000-ton detectors DØ and CDF inside the Tevatron tunnel at energies of 1. 96 TeV, revealing the structure of matter at the smallest scale.

Physicists would contribute by assessing the changes in light transmission in the receiving waters.

Physicists working on the project adopted the name " barn " for a unit equal to 10 < sup >− 24 </ sup > square centimetres, about the size of a uranium nucleus.

* Le Bon, Gustave, The Crowd: a study of the Popular Mind ( 1895 )

John Stuart Mill seems to have been an advocate of a type of logical psychologism, as were many nineteenth-century German logicians such as Sigwart and Erdmann as well as a number of psychologists, past and present: for example, Gustave Le Bon.

Other key theorists include Gustave Le Bon ( 1841 – 1931 ) who believed that crowds possessed a ' racial unconscious ' with primitive, aggressive, and antisocial instincts, and William McDougall ( psychologist ), who believed in a ' group mind ,' which had a distinct existence born from the interaction of individuals.

Gustave Le Bon was a French social psychologist whose seminal study, The Crowd: A Study of the Popular Mind ( 1896 ) led to the development of group psychology.

Other major thinkers of crowd psychology include René Girard, Gustave Le Bon, Wilfred Trotter, Gabriel Tarde, Sigmund Freud, Elias Canetti, Steve Reicher and Julia Constintine.

These three then inspired a fourth monograph by French physician and popular science writer Gustave Le Bon, La Psychologie des foules ( 1895 ).

According to pioneer Gustave Le Bon, this resulted in ‘ mental unity ’.

He combined the ideas of Gustave Le Bon and Wilfred Trotter on crowd psychology with the psychoanalytical ideas of his uncle, Sigmund Freud.

Gustave Le Bon ( 7 May 1841 – 13 December 1931 ) was a French social psychologist, sociologist, and amateur physicist.

Among the concepts that Tarde initiated were the group mind ( taken up and developed by Gustave Le Bon, and sometimes advanced to explain so-called herd behaviour or crowd psychology ), and economic psychology, where he anticipated a number of modern developments. Tarde was very critical of Durkheim ’ s work at the level of both methodology and theory.

Class consciousness, as described by Georg Lukács's famous History and Class Consciousness ( 1923 ), is opposed to any psychological conception of consciousness, which forms the basis of individual or mass psychology ( see Freud or, before him, Gustave Le Bon ).
