If chemical compounds can be proved by experiment to obey these laws, then the atomic theory acquires a high degree of probability; if they are contradicted by experiment then the atomic theory must be abandoned, or very much modified.
Quinn's experiment is very important to him.
I thought, however, that the advantage she would derive would not repay her for the time and labour that such an experiment would cost.
How could youths better learn to live than by at once trying the experiment of living?
At La Carlota the Spanish government established a station for the study of the culture of sugar-cane; by the American government this has been converted into a general agricultural experiment station, known as "Government Farm."
In the next experiment the air was compressed as before, and then allowed to escape through a long lead tube immersed in the water of a calorimeter, and finally collected in a bell jar.
The experiment was interesting, but of course came to little.
In water and in ethylene experiment shows that 8 parts by weight of oxygen and 6 parts of carbon, respectively, are in union with one part of hydrogen; also, if the diagrams are correct, these numbers must be in the ratio of the atomic weights of oxygen and carbon.
Similarly, if we know by experiment the composition of water and of ammonia, we can predict the probable composition of the oxides of nitrogen.
They agree very well with experiment, and require us to suppose that the vibrations are perpendicular to the plane of polarization.
It must be conceded as no small merit in Lydgate that, in an age of experiment he should have succeeded so often in hitting the right word.
The temperature of the water at the commencement of the experiment was 60° Fahr., and after two horses had turned the lathe for 22 hours the water boiled.
The experiment is, in fact, much improved by passing the primary light through a coloured glass.
It is the seat of the New York State Agricultural Experiment Station and of Hobart College (nonsectarian), which was first planned in 1812, was founded in 1822 (the majority of its incorporators being members of the Protestant Episcopal church) as successor to Geneva Academy, received a full charter as Geneva College in 1825, and was renamed Hobart Free College in 1852 and Hobart College in 1860, in honour of Bishop John Henry Hobart.
Possessing an immense range of knowledge, he has filled up lacunae in nearly every part of physics, by experiment, by calculation, and by clear accurate thought.
The department of agriculture has an experiment station, established by the state in 1896, in which important experiments in cotton breeding have been carried on.
He did not, however, infer that since the heat could not have been supplied by the ice, for ice absorbs heat in melting, this experiment afforded conclusive proof against the substantial nature of heat.
In this experiment a great noise was produced, corresponding to a loss of energy, and Joule endeavoured to determine the amount of energy necessary to produce an equal amount of sound from the string of a violoncello and to apply a corresponding correction.
There is some reason to hope that the day of these misconceptions is passed; although there is also some reason to fear that on other grounds the present era may be known to posterity as an era of instrumentation comparable, in its gorgeous chaos of experiment and its lack of consistent ideas of harmony and form, only to the monodic period at the beginning of the 17th century, in which no one had ears for anything but experiments in harmonic colour.
But experiment shows that in this condition much of the violin part sounds incomplete; and the truth appears to be that Haydn is thinking, like any modern composer, of the opposition of two solid bodies of tone - the pianoforte and the stringed instruments.
The weakness of the government in dealing with the strike riots caused a feeling of profound dissatisfaction, and the so-called experiment of liberty, conducted with the object of conciliating the extreme parties, proved a dismal failure.
A similar experiment had been tried in France not without success.
The relationships existing between these enzymes are still the subjects of experiment, and we cannot regard them as exhaustively examined.
It is applied more particularly to the investigations of those who devote themselves to the study of pure as opposed to applied science, to the investigation of causes rather than to practical experiment; thus while every surgeon or physician who treats an individual case of cancer may add to our sum of knowledge of the disease, the body of trained investigators which is endowed by the Cancer Research Fund are working on different lines.
I had the previous winter made a small quantity of lime by burning the shells of the Unio fluviatilis, which our river affords, for the sake of the experiment; so that I knew where my materials came from.
The hyposulphite experiment here again affords an excellent illustration.
He now resolved to try the experiment of applying photography to the determination of stellar parallax.
There is this difference, however, between this experiment and the operation imagined by Maxwell, that when the gases have diffused the experiment cannot be repeated; and it is no more contrary to the dissipation of energy than is the fact that work may be derived at the expense of heat when a gas expands into a vacuum, for the working substance is not finally restored to its original condition; while Maxwell's "demons" may operate without limit.
In 1768 he had published Institutiones metallurgicae, intended to give a scientific form to chemistry by digesting facts established by experiment into a connected series of propositions.
As with other duplex systems it is possible to obtain several approximately correct adjustments with the bridge and its accessories, but only one gives a true balance, and careful experiment is required to make sure that this is obtained.
Following on this he made an interesting experiment, using Morse's method, to connect the Isle of Wight telegraphically with the mainland, by conduction across the Solent in two places, during a temporary failure of the submarine cable in 1882 in that channel.
Following on this first experiment, the East India Company, in 1841, proposed to maintain a permanent flotilla on the Tigris and Euphrates, and set two vessels, the " Nitocris " and the " Nimrod," under the command of Captain Campbell of the Indian navy, to attempt the ascent of the latter river.
The experiment was so far successful that, with incredible difficulty, the two vessels did actually reach Meskene, but the result of the expedition was to show that practically the river could not be used as a high-road of commerce, the continuous rapids and falls during the low season, caused mainly by the artificial obstructions of the irrigating dams, being insurmountable by ordinary steam power, and the aid of hundreds of hands being thus required to drag the vessels up the stream at those points by main force.
He made various reforms which were badly wanted in army administration, but on the whole the experiment of a civilian War Lord was not a complete success, and in April 1909 Senator Casana retired and was succeeded by General Spingardi, an appointment which received general approval.
In 1831 Wheatstone by his " magic lyre" experiment showed that, when the sounding-boards of two musical instruments are connected together by a rod of pine wood, a tune played on one will be faithfully reproduced by the other.
On repeating the experiment when the two vessels were placed in different calorimeters, it was found that heat was absorbed by the vessel containing the compressed air, while an equal quantity of heat was produced in the calorimeter containing the exhausted vessel.
