Stellarator configurations such as the proposed NCSX, a quasi-axisymmetric stellarator design,

Fusion devices generally fell into two classes, pulsed machines like the z-pinch that attempted to reach high densities and temperatures but only for microseconds, while steady state concepts such as the stellarator and magnetic mirror attempted to reach the Lawson criterion through longer confinement times.

Princeton Plasma Physics Laboratory started building a new stellarator, NCSX, but as of 2008, work was abandoned due to high costs.

The Helias has been proposed to be the most promising stellarator concept for a power plant, with a modular engineering design and optimised plasma, MHD and magnetic field properties.

He contends this idea doesn't conflict with experiments on which the principle of conservation of matter and energy is based because some slight error must be assumed in such experiments.

He devised experiments such as the ignition of methane by an electric spark in a closed vessel.

The CDC thus only recommends vaccination for: 1 ) All laboratory and field personnel who are working with Y. pestis organisms resistant to antimicrobials, 2 ) People engaged in aerosol experiments with Y. pestis and 3 ) People engaged in field operations in areas with enzootic plague where preventing exposure is not possible ( such as some disaster areas ).

Cosmological perturbation theory, which describes the evolution of slight inhomogeneities in the early universe, has allowed cosmologists to precisely calculate the angular power spectrum of the radiation, and it has been measured by the recent satellite experiments ( COBE and WMAP ) and many ground and balloon-based experiments ( such as Degree Angular Scale Interferometer, Cosmic Background Imager, and Boomerang ).

Furthermore, unforeseen side effects of ion propulsion might in some way interfere with typical scientific experiments, such as fields and particle measurements.

There are experiments in which the wave and particle natures of electromagnetic waves appear in the same experiment, such as the self-interference of a single photon.

Others have argued that data such as the Bereitschaftspotential undermine epiphenomenalism for the same reason, that such experiments rely on a subject reporting the point in time at which a conscious experience occurs, thus relying on the subject to be able to consciously perform an action.

These experiments are used to prove, verify, and reinforce laws and theorems such as Ohm's law, Kirchhoff's laws, etc.

However, today many schools use progressive education methods, such as hands on activities and science experiments in Junior High Schools.

In basic chemistry scientists are typically interested in experiments conducted at atmospheric pressure, and for reaction energy calculations they care about the total energy in such conditions, and therefore typically need to use H. Furthermore the enthalpy is the working horse of engineering thermodynamics as we will see later.

Most physicists who have examined the matter concur that experiments, such as those of Alain Aspect and his group, have confirmed that physical probabilities, as predicted by quantum

Some workers in the field have also attempted to formulate hidden variable theories that exploit loopholes in actual experiments, such as the assumptions made in interpreting experimental data, although no theory has been proposed that can reproduce all the results of quantum mechanics.

B. Rhine worked largely in the laboratory, carefully defining terms such as ESP and psi and designing experiments to test them.

In all such experiments order of the cards must be random so that hits are not obtained through systematic biases or prior knowledge.

Recently the tram has seen a very big revival with many experiments such as ground level power supply in Bordeaux, or trolleybuses pretending to be trams in Nancy.

Captive balloons may be more convenient for such experiments, because kite-carried antennas require a lot of wind, which may be not always possible with heavy equipment and a ground conductor.

In 1953, Brian Pippard, motivated by penetration experiments, proposed that this would modify the London equations via a new scale parameter called the coherence length.

Many experiments to detect proposed dark matter particles through non-gravitational means are underway.

Gettier proposed two thought experiments, which have come to be known as " Gettier cases ," as counterexamples to the classical account of knowledge.

Mariners had noticed that lightning strikes had the ability to disturb a compass needle, but the link between lightning and electricity was not confirmed until Benjamin Franklin's proposed experiments in 1752.

A methodology for designing experiments was proposed by Ronald A. Fisher, in his innovative books: " The Arrangement of Field Experiments " ( 1926 ) and The Design of Experiments ( 1935 ).

In her book The Shock Doctrine, author and social activist Naomi Klein criticized Friedman's ideology and the principles that guided the economic restructuring that followed the military coups in countries such as Chile and Indonesia, drawing analogies between the way that Friedman proposed using the social " shock " of the coups to create an economic " blank slate " with Ewen Cameron's controversial medical experiments that used electroshock therapy to create a mental " blank slate " in patients with mental disorders.

Learning from these experiments, Danish physicist Niels Bohr proposed in 1913 that the electrons in atoms are arranged in shells surrounding the nucleus, and that for all noble gases except helium the outermost shell always contains eight electrons.

James Bjorken proposed that pointlike partons would imply certain relations should hold in deep inelastic scattering of electrons and protons, which were spectacularly verified in experiments at SLAC in 1969.

The inventor proposed to make new experiments, but, chagrined at the raillery of the common people, who called him wizzard, and terrified by the Inquisition, he took the advice of his friends, burned his manuscripts, disguised himself, and fled to Spain, where he soon after died in an hospital.

Inspired by Harry Harlow's famous experiments on rhesus monkeys, which established a link between neurotic behavior and isolation from a care-giving mother, Prescott further proposed that a key component to development comes from the somesthetic processes ( body touch ) and vestibular-cerebellar processes ( body movement ) induced by mother-child interactions, and that deprivation of this stimulation causes brain abnormalities.

After animal experiments researchers of a pharmaceutical company have proposed N-acetylcarnosine as a treatment for ocular disorders that have a component of oxidative stress in their genesis, including cataracts, glaucoma, retinal degeneration, corneal disorders, and ocular inflammation.

This equation was also proposed by van der Waals, who further proposed that could be given by the expression,, where is a universal constant for all liquids, and is the critical pressure of the liquid ( although later experiments found to vary to some degree from one liquid to another ).

Lead and the Homestake Mine have been selected as the site of the Deep Underground Science and Engineering Laboratory, a proposed NSF facility for low-background experiments on neutrinos, dark matter, and other nuclear physics topics, as well as biology and mine engineering studies.

The earliest constants of motion discovered were momentum and energy, which were proposed in the 17th century by René Descartes and Gottfried Leibniz on the basis of collision experiments, and refined by subsequent researchers.

An alternative theory was proposed by Peter J. Gierasch in the following year which held instead that the meridional ( Hadley ) circulation may transport the momentum by eddy-mixing .< ref > The actual cause of this phenomenon continues to be debated in the literature, with GCM experiments suggesting that both the Fels / Lindzen and Gierasch mechanisms are involved.

In 1965, Hannes Alfvén proposed a " plasma cosmology " theory of the universe based in part on scaling observations of space plasma physics and experiments on plasmas in terrestrial laboratories to cosmological scales orders-of-magnitude greater.

Alfvén proposed the use of plasma scaling to extrapolate the results of laboratory experiments and space plasma physics observations to scales orders-of-magnitude greater ( see box ).

The French Academy of Sciences originated the first recorded blind experiments in 1784: the Academy set up a commission to investigate the claims of animal magnetism proposed by Franz Mesmer.

Each time a newer set of laws is proposed, it is required that in the limiting situations in which the older set of laws were tested against experiments, the newer laws are nearly identical to the older laws, to within the measurement uncertainties of the older measurements.

Although there is little publicly available data from the Halite-Centurion series, the results, augmented by experiments on the Nova laser, supported detailed simulations that ignition and net energy gains could be achieved with a few MJ, or energies close to those originally proposed by Nuckolls.

It had been proposed to De Winter to make up for the want of skill by firing shell from the lower deck guns ; and some experiments had been made during the summer which showed that the idea was feasible ; but want of familiarity with an arm so new and so dangerous presumably prevented its being acted on in the battle.
