The term " Golgi apparatus " was used in 1910 and first appeared in scientific literature in 1913.

Based on these descriptions and the Byzantine sources, John Haldon and Maurice Byrne reconstructed the entire apparatus as consisting of three main components: a bronze pump ( the σίφων, siphōn proper ), which was used to pressurize the oil ; a brazier, used to heat the oil ( πρόπυρον, propyron, " pre-heater "); and the nozzle, which was covered in bronze and mounted on a swivel ( στρεπτόν, strepton ).

His measurements of the tiny effect produced in the apparatus he used were an experimental tour de force, accomplished 18 years before the electron was discovered.

Infrared imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

According to his first book, The Silent World: A Story of Undersea Discovery and Adventure ( 1953 ), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur.

* Boarding an apparatus used for gymnastics, such as a balance beam

Mirrors are also used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery.

The Genoese likely got this beverage with the help of the alchemists of Provance, who used the Arab-invented distillation apparatus to convert grape must into alcohol.

A number of problems with that execution ( inappropriate behavior by spectators, incorrect assembly of the apparatus, and the fact it was secretly filmed ) caused the authorities to conduct future executions in the prison courtyard.

Communication is made via a kind of instant messaging / video conferencing machine called the speaking apparatus, with which people conduct their only activity, the sharing of ideas and knowledge.

This method needs no special apparatus and is easy to conduct.

In February 1801, Oersted did manage to experiment with physical apparatus and reported experiments made with a voltaic battery of 600 plates of zinc and silver and of later experiments with a battery of 60 plates of zinc and lead.

The delayed-choice experiment and the quantum eraser are sophisticated variations of the double-slit with particle detectors placed not at the slits but elsewhere in the apparatus.

Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the " factitious airs " had come to a dead end. Scientific apparatus designed by Boulton and Watt in preparation of the Pneumatic Institution in Bristol

In this theory the reason the Michelson-Morley experiment " failed " was that the apparatus contracted in length in the direction of travel.

The apparatus was more than accurate enough to detect the expected effects, but he obtained a null result when the first experiment was conducted in 1881, and again in 1887.

The beauty of the oil-drop experiment is that as well as allowing quite accurate determination of the fundamental unit of charge, Millikan's apparatus also provided a ' hands on ' demonstration that charge is actually quantized.

The income from the shop and his new inventions gave him enough money to experiment on new tricks using glass apparatus that would be ( or at least appear ) free of trickery.

The measurement problem is resolved by this theory since the outcome of an experiment is registered by the configuration of the particles of the experimental apparatus after the experiment is completed.

Because the reaction had been initiated by trace oxygen contamination in their apparatus, the experiment was, at first, difficult to reproduce.

In 1930, Georg Joos conducted an experiment using an automated interferometer with 21-meter-long arms forged from pressed quartz having very low thermal coefficient of expansion, that took continuous photographic strip recordings of the fringes through dozens of revolutions of the apparatus.

The apparatus Cavendish used for weighing the Earth was a modification of the torsion balance built by Englishman and geologist John Michell, who died before he could begin the experiment.

The apparatus was sent in crates to Cavendish, who completed the experiment in 1797 – 1798, and published the results.

Foucault based his apparatus on an earlier experiment by Fizeau ( Figure 2 ) who, in 1849, used two fixed mirrors, one partially obscured by a rotating cogwheel.

The term " empirical methods " refers to experiment, disclosure of apparatus for reproduction of experiments, and other ways in which science is validated by scientists.

Fair sampling assumes that these inefficiencies are unrelated to the hidden variables ; in other words, the number of triples actually detected in any run of the experiment is proportional to the number that would have been detected if the apparatus had no inefficiencies-with the same constant of proportionality for all possible settings of the apparatus.

Oil drop experiment apparatus

From the time when in about 1840 he fitted up some simple physical apparatus in his rooms in Pembroke College, mathematics and experiment ever went hand in hand, aiding and checking each other.

In 1850, he did an experiment using the Fizeau – Foucault apparatus to measure the speed of light ; it came to be known as the Foucault – Fizeau experiment, and was viewed as " driving the last nail in the coffin " of Newton's corpuscle theory of light when it showed that light travels more slowly through water than through air.

Following on with the basic apparatus as the earlier Michelson-Morley experiment, Miller and Morley published another null result in 1904.

In particular he felt that Miller did not take enough care in guarding against thermal gradients in the room where the experiment took place, as, unlike most interferometry experiments, Miller conducted his in a room where the apparatus was deliberately left open to the elements to some degree.

While the Michelson – Morley experiment showed that the speed of light is independent of the orientation of the apparatus, the Kennedy – Thorndike experiment showed that it is also independent of the velocity of the apparatus in different inertial frames.
