Experiments upon this subject are not difficult.
Did my crazy husband's experiments keep you up all night?
He had just constructed a boat that could be propelled by a kite with the wind in its favor, and one day he tried experiments to see if he could steer the kite against the wind.
Quinn could poke around with his experiments on his own time as he'd done all summer.
You can't trust the good guys, because they'll use you for science experiments, and the bad guys put you in Hell.
Gerdien has more recently repeated the experiments, employing an apparatus devised by him for the purpose.
Of late years many experiments have been made on the influence of electric fields or currents on plant growth.
The best-known of Joule's experiments was that in which a brass paddle consisting of eight arms rotated in a cylindrical vessel of water containing four fixed vanes, which allowed the passage of the arms of the paddle but prevented the water from rotating as a whole.
Here in Dr. Bell's laboratory, or in the fields on the shore of the great Bras d'Or, I have spent many delightful hours listening to what he had to tell me about his experiments, and helping him fly kites by means of which he expects to discover the laws that shall govern the future air-ship.
Laura Bridgman was born at Hanover, New Hampshire, December 21, 1829; so she was almost eight years old when Dr. Howe began his experiments with her.
The aurists then tried their experiments with quite different results.
The human race is interested in these experiments, though a few old women who are incapacitated for them, or who own their thirds in mills, may be alarmed.
I'd like space to do some independent experiments too.
According to his notes, far more experiments were conducted than were ever discussed with us.
Something about science experiments, Megan said, poking her head in.
In each of a number of experiments he found that the weight of the silver iodide did not differ by one twenty-thousandth of the whole from the sum of the weights of the silver and the iodine used.
One of these experiments may be described.
It was not until the middle of the 18th century that experiments due to Benjamin Franklin showed that the electric phenomena of the atmosphere are not fundamentally different from those produced in the laboratory.
Ramsay, repeating these experiments, found that the inert gas emitted refused xIIl.
S., is famous in connexion with the socialist experiments of Robert Owen.
The results of these first experiments were not encouraging, owing mainly to the poor class of animals, but the exporters persevered, and the business steadily grew in value and importance, until in 1898 the number of live cattle shipped was 359,296, which then decreased to 119,189 in 1901, because of the foot-and-mouth disease.
P. Reeves, State Experiments in Australia and New Zealand; A.
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.
"It is hardly necessary to add," he remarks, "that anything which any insulated body or system of bodies can continue to furnish without limitation cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner that heat was excited and communicated in these experiments, except it be motion."
P. Joule to achieve; his experiments conclusively prove that heat and energy are of the same nature, and that all other forms of energy can be transformed into an equivalent amount of heat.
In such experiments the molecular energy of a gas is converted into work only in virtue of the molecules being separated into classes in which their velocities are different, and these classes then allowed to act upon one another through the intervention of a suitable heat-engine.
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.
Elec. Eng., 2 7, p. 869.) In 1899 experiments were made atMenai Straits to put the lighthouse at the Skerries into communication with the coastguard station at Cemlyn.
The machine will figure this out as it collects more data and incorporates more variables, and then experiments on people to see which combinations of factors work the best.
Essentially, we will be able to run as many controlled experiments as we can imagine instantly and for no cost—and that will revolutionize medicine.
Farming will be done on such a scale that thousands of experiments can be happening at any one time, putting a tiny fraction of the produce at risk.
She cannot sing and she cannot play the piano, although, as some early experiments show, she could learn mechanically to beat out a tune on the keys.
It is evident that if our experiments are solely directed to the verification of this law, they should, if possible; be carried out in a hermetically closed vessel, the vessel and its contents being weighed before and after the chemical change.
The extremely careful experiments of this kind, by H.
Such analyses, which do not always admit of great accuracy, have been confirmed by a few carefully planned experiments in which two components were brought together under very varied conditions, and the resulting compound analysed.
Stas carried out such experiments on the composition of silver chloride and of ammonium chloride, but he never found a variation of one part in 10,000 in the composition of the substances.
Berzelius saw at once that it afforded an admirable test for the correctness of Dalton's views, and he made numerous experiments expressly designed to test the law.
It gives name to a school of gunnery, where officers are instructed and experiments carried out.
Brown, who described experiments which were in disagreement with Pasteur's dictum.
Although the direct object of Pasteur was to prove a negative, yet it was on these experiments that sterilization as known to us was developed.
Another point of great importance is well brought out in the experiments of John Tyndall (Phil.
The experiments of Tyndall upon precipitated clouds have been already referred to.
Experiments by F.
He also carried out many experiments in magneto-optics, and succeeded in showing, what Faraday had failed to detect, the rotation under the influence of magnetic force of the plane of polarization in certain gases and vapours.
This result was apparently confirmed by some independent experiments, but it Is very far from the truth, for it is now known that the actual ratio, or factor as it is commonly called, of the velocity of the wind to that of the cups depends very largely on the dimensions of the cups and arms, and may have almost any value between two and a little over three.
It was given about the end of the 18th century as based on some experiments, but with a footnote stating that little reliance could be placed on it.
In the treatment of the orchestra volumes might be written about Haydn's and Mozart's sense of fitness, as shown in Haydn's experiments and Mozart's settled methods.
Highton in experiments described in 1872, also revived the same suggestion for wireless telegraphy.
Experiments of this kind were actually tried by Graham Bell in 1882, with boats on the Potomac river, and signals were detected at a distance of a mile and a half.
In 1885 Preece and Heaviside proved by experiments made at Newcastle that if two completely insulated circuits of square form, each side being 440 yds., were placed a quarter of a mile apart, telephonic speech was conveyed from one to the other by induction, and signals could be perceived even when they were separated by 1000 yds.
The method of induction between insulated primary and secondary circuits laid out flat on the surface of the earth proves to be of limited application, and in his later experiments Preece returned to a method which unites both conduction and induction as the means of affecting one circuit by a current in another.
Other experiments in inductive telegraphy were made by Preece, aided by the officials of the British Postal Telegraph Service, in Glamorganshire in 1887; at Loch Ness in Scotland in 1892; on Conway Sands in 1893; and at Frodsham, on the Dee, in 1894.
Rathenau of Berlin made many experiments in 1894 in which, by means of a conductive system of wireless telegraphy, he signalled through 3 m.
Several experiments were tried, to determine positively whether or not she had any perception of sound.
Morse showed, by experiments made in 1842 on a canal at Washington, that it was possible to interrupt the metallic electric circuit in two places and yet retain power of electric Morse.
All experiments are fruitful if you don't have any preconceived notions about the results.
Another of Ully's experiments. Hopefully it's better than his demon skunk spray.
As she did every day, she went to the table near his cluttered desk to await her blood draw and any other experiments he wanted to do.
Berzelius, and somewhat later, in the experiments of the Belgian chemist J.
