To try to oppose the general religious and moral conviction of such a majority by a legislative fiat would be to invite the same breakdown of law and order that was occasioned by the ill-starred Prohibition experiment.

A sense of self-certainty and the freedom to experiment with different roles, or confidence in one's own unique behavior as an alternative to peer-group conformity, is more easily developed during adolescence if, during early childhood, the individual was permitted to exercise initiative and encouraged to develop some autonomy.

Altruism, the experiment suggested, was not a superior moral faculty that suppresses basic selfish urges but rather was basic to the brain, hard-wired and pleasurable.

It is a popular belief that alchemists made contributions to the " chemical " industries of the day — ore testing and refining, metalworking, production of gunpowder, ink, dyes, paints, cosmetics, leather tanning, ceramics, glass manufacture, preparation of extracts, liquors, and so on ( it seems that the preparation of aqua vitae, the " water of life ", was a fairly popular " experiment " among European alchemists ).

The experiment showed that after removing this bacteria, healthy bacteria was able to move in and replace the habitat and preventing S. mutans from regrowing.

For example, antibacterial selection within whole bacterial populations for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the Luria – Delbrück experiment.

In an article he submitted for the medical journal The Lancet during World War I, Fleming described an ingenious experiment, which he was able to conduct as a result of his own glass blowing skills, in which he explained why antiseptics were killing more soldiers than infection itself during World War I. Antiseptics worked well on the surface, but deep wounds tended to shelter anaerobic bacteria from the antiseptic agent, and antiseptics seemed to remove beneficial agents produced that protected the patients in these cases at least as well as they removed bacteria, and did nothing to remove the bacteria that were out of reach.

The first person to experiment in this fashion was Francis Herbert Wenham, who in doing so constructed the first wind tunnel in 1871.

The 1904 Thomson model was disproved by the 1909 gold foil experiment, which was interpreted by Ernest Rutherford in 1911

The experiment was abandoned the following season.

The frequency of new enhancing lesions as detected by Gd-enhanced MRI was reduced by more than half in 12 patients, comparing the six-month run-in phase to the six-month post-BCG phase of the experiment.

By repeating the experiment with particles of inorganic matter he was able to rule out that the motion was life-related, although its origin was yet to be explained.

The October experiment allegedly took place while the ship was on its first shakedown cruise in the Bahamas, although proponents of the story claim that the ship's logs might have been falsified, or else still be classified.

He allegedly died in an explosion of an alchemical experiment in the " Hotel zum Löwen " in Staufen im Breisgau.

By the mid 70's, it existed only as chunks of rubble, after destruction in an experiment in more exciting pot fires allegedly involving newspaper, xylene, and matches.

John William Strutt, 3rd Baron Rayleigh | Lord Rayleigh's method for the isolation of argon, based on an experiment of Henry Cavendish's.

Many find aberration to be counter-intuitive, and a simple thought experiment based on everyday experience can help in its understanding.

But it is not known if any experiment based on this idea has been ever achieved.

It is also used to form reasonable hypotheses about complex physical situations that can be tested by experiment or by more developed theories of the phenomena, and to categorize types of physical quantities and units based on their relations to or dependence on other units, or their dimensions if any.

Depending on the outcomes of the experiment, the theory on which the hypotheses and predictions were based will be supported or not.

Armstrong was of the opinion that anyone who had actual contact with the development of radio understood that the radio art was the product of experiment and work based on physical reasoning, rather than on the mathematicians ' calculations and formulae ( known today as part of " mathematical physics ").

The von Neumann description of quantum measurement of an observable A, when the system is prepared in a pure state ψ is the following ( note, however, that von Neumann's description dates back to the 1930s and is based on experiments as performed during that time – more specifically the Compton – Simon experiment ; it is not applicable to most present-day measurements within the quantum domain ):

# The experiment should be so designed and based on the results of animal experimentation and a knowledge of the natural history of the disease or other problem under study that the anticipated results will justify the performance of the experiment.

In the early 11th century, Alhazen ( Ibn al-Haytham ) wrote the Book of Optics ( Kitab al-manazir ) in which he explored reflection and refraction and proposed a new system for explaining vision and light based on observation and experiment.

In the most common experiment of this type, a true random number generator ( RNG ), based on electronic or radioactive noise, produces a data stream that is recorded and analyzed by computer software.

However, using data from an internet survey based experiment performed in 2006 on a random sample of 574 adult university students, a study was conducted that examined public approval for the use of racial profiling to prevent crime and terrorism.

One very early experiment in electrical telegraphy was an electrochemical telegraph created by the German physician, anatomist and inventor Samuel Thomas von Sömmering in 1809, based on an earlier, less robust design of 1804 by Spanish-Catalan polymath and scientist Francisco Salva Campillo.

In science, the term " theory " refers to " a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

* Home experiment based on index matching between glass and paint thinner

At least one other group based in central Europe has attempted to replicate Podkletnov's gravity impulse generator experiment, but they have elected not to publish their results.

The same experiment, known as ICARUS and based on a new technique of electronic detection of ionizing events in ultra-pure liquid argon, is aiming at the direct detection of the neutrinos emitted from the Sun, a first rudimentary neutrino telescope to explore neutrino signals of cosmic nature.

An experiment based on flux quantization of a three-grain ring of YBa < sub > 2 </ sub > Cu < sub > 3 </ sub > O < sub > 7 </ sub > ( YBCO ) was proposed to test the symmetry of the order parameter in the HTS.

The calculation that underlies the Casimir experiment, a calculation based on the formula predicting infinite vacuum energy, shows the zero-point energy of a system consisting of a vacuum between two plates will decrease at a finite rate as the two plates are drawn together.

Another precedent to the prepared piano was an experiment by the French composer Maurice Delage ( 1879 – 1961 ): his Ragamalika ( 1912 – 22 ), based on the classical music of India, calls for a piece of cardboard to be placed under the B-flat in the second line of the bass clef to dampen the sound, imitating the sound of an Indian drum.

In the 1 February 2007 issue of Nature, David Leigh, a professor at the University of Edinburgh, announced the creation of a nano-device based on Feynman's thought experiment.
