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 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 often have a very precise mathematical theory describing how a system will behave.

The extant books have the traditional titles Against the Logicians ( books VII-VIII ), Against the Physicists ( books IX-X ), and Against the Ethicists ( book XI ).

Against the Mathematicians VII-XI is sometimes distinguished from Against the Mathematicians I-VI by giving it the title Against the Dogmatists ( in which case Against the Logicians are called books I-II, Against the Physicists are called books III-IV, and Against the Ethicists is called book V, despite the fact that it is commonly believed that the beginning of the work is missing and it is not known how many books might have preceded the extant books ).

Physicists such as Alain Aspect and Paul Kwiat have performed experiments that have found violations of these inequalities up to 242 standard deviations ( excellent scientific certainty ).

Physicists tend to have significantly less experience of statistical techniques, and thus lean on approaches based upon partial differential equations, and solutions to these based upon numerical analysis.

Physicists have argued over whether fractals can be used to authenticate the paintings.

Physicists have also developed other MRI-based techniques such as magnetic resonance spectroscopy ( for measuring some key metabolites such as N-acetylaspartate and lactate within the living brain ) and diffusion tensor imaging ( for mapping white matter tracts within the living brain ).

* Physicists at Brookhaven National Laboratory announce that they have created a newly discovered state of matter by smashing atoms in the Relativistic Heavy Ion Collider.

Physicists such as Stephen Hawking and Roger Penrose have suggested that universes both fork and combine, which could be visualized as more of a system of roads and pathways.

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 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 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 showed in the 1920s that in gas at extremely low densities — even interstellar matter considered dense in an astronomical context is at high vacuum by laboratory standards — electrons can populate excited metastable energy levels in atoms and ions which at higher densities are rapidly de-excited by collisions.

Physicists Rudolf Fleischmann and Carl Friedrich von Weizsäcker were known to be working at the University of Strasbourg, as was Eugen von Haagen, an expert on viruses whose work was of great concern to the Alsos Mission's Biological Warfare Section.

Physicists then, as now, often look at a property with the word " available " or " utilizable " in its name with a certain unease.

* Physicists Demonstrate Qubit-Qutrit Entanglement by Lisa Zyga at Physorg. com, February 26, 2008.

Physicists can look at this trail of ions and determine the path that the particle took.

His books include The Physicists ( 1978 ), a history of the American physics community, In the Name of Eugenics ( 1985 ), currently the standard text on the history of eugenics in the United States, and The Baltimore Case ( 1998 ), a study of accusations of scientific fraud.

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

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

: Physicists do of course carry around with them a working philosophy.

The therapist works closely with the Radiation oncologists, Medical Physicists and other members of the health care team.

" Physicists attempt to reduce the complexity of nature to a single unifying theory, of which the most successful and universal, the quantum theory, has been associated with several Nobel prizes, for example those to Dirac and Heisenberg.

Physicists are unable to demonstrate experimental and astrophysical constraints of zero probability of catastrophic events, nor that tomorrow Earth will be struck with a " doomsday " cosmic ray ( they can only calculate an upper limit for the likelihood ).

Physicists Bret M. Huggard and Richard L. Kautz came up with a mathematical equation that approximates the motion of the Tilt-A-Whirl.

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.

Physicists argue that space-time can be understood as a sort of stretchy fabric that can bend due to forces such as gravity.

• Ames Lab Physicists succeed in growing the first large crystal of solid helium

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

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

Biographies of Famous Electrochemists and Physicists Contributed to Understanding of Electricity.

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 Gustave le Bon and P. Audollet and spiritualist

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