His gaze traveled over her face, detecting something that touched his mouth with a slight smile.
But in the mode of detecting these swarming bodies, a typical change was made on the 22nd of December 1891, Max Wolf.
The phenomena of chromatic polarization afford a ready means of detecting doubly refracting structure in cases, such as that produced in isotropic bodies by strain, in which its effects are very minute.
Then we started hearing all this nonsense about Byrne until it got us wondering if there might be something to it, so we did a little detecting ourselves.
Hence devices for detecting the oscillations in the antenna are merely very sensitive forms of ammeter and voltmeter.
These wave-detecting devices may be divided into two classes: (i) potential operated detectors, and (ii) current operated detectors.
Klaproth and Vauquelin also investigated this earth, but without detecting that it was a complex mixture - a discovery reserved for C. G.
The imperfections of the thermopile, with which he began his work, led him, about 1880, to the invention of the bolometer, an instrument of extraordinary delicacy, which in its most refined form is believed to be capable of detecting a change of temperature amounting to less than one-hundred-millionth of a degree Centigrade.
He belongs distinctly to the romantic school; his forte is vivid and picturesque description, the lively presentation of scenes and actions, characters and states of society, not the subtle analysis of motives, the power of detecting the undercurrents or the generalizing faculty.
He advanced towards the modern view of elements as the undecomposable constituents of material bodies; and understanding the distinction between mixtures and compounds, he made considerable progress in the technique of detecting their ingredients, a process which he designated by the term "analysis."
But the essential narrowness and timidity of his general outlook prevented him from detecting and estimating latent forces, either in politics or in matters strictly intellectual and moral; and this lack of understanding and sympathy accounts for his distrust and dislike of the passion and fancy of Shelley and Keats, and for his praise of the half-hearted and elegant romanticism of Rogers and Campbell.
For the rest of his life Walsingham was mainly occupied in detecting and frustrating the various plots formed against Elizabeth's life; and herein he achieved a success denied him in his foreign policy.
This instrument was devised for the purpose of detecting counterfeit coin, especially guineas and half-guineas.
It is a vast mine of experimental observation on the symptoms of poisoning of all kinds, on the appearances which poisons leave in the dead body, on their physiological action, and on the means of detecting them.
Macpherson is said to have sent Johnson a challenge, to which Johnson replied that he was not to be deterred from detecting what he thought a cheat by the menaces of a ruffian.
Until means are devised for detecting aurora during bright sunshine, our knowledge as to the hour at which these causes are most frequently or most powerfully in operation must remain incomplete.
ELECTROSCOPE, an instrument for detecting differences of electric potential and hence electrification.
To employ the electroscope as a means of detecting radio-activity, we have first to test the leakage quality of the electroscope itself.
The credit for detecting its value belongs to the late Gaston Paris, although his edition (1897) was partially anticipated by the editors of the Monumenta Germaniae Historica, who published some selections in the twenty-seventh volume of their Scriptores (1885).
The accuracy of his measurement, by which he established within 2% the above law, was only limited by the sensibility, or rather insensibility, of the pith ball electrometer, which was his only means of detecting the electric charge.2 In the accuracy of his quantitative measurements and the range of his researches and his combination of mathematical and physical knowledge, Cavendish may not inaptly be described as the Kelvin of the 18th century.
He ascertained the distribution of electricity among several spheres (whether equal or unequal) placed in contact in a straight line; and he measured the distribution of 2 In 1878 Clerk Maxwell repeated Cavendish's experiments with improved apparatus and the employment of a Kelvin quadrant electrometer as a means of detecting the absence of charge on the inner conductor after it had been connected to the outer case, and was thus able to show that if the law of electric attraction varies inversely as the nth power of the distance, then the exponent n must have a value of 2 t Isua.
It led at once to the construction of the galvanometer as a means of detecting and measuring the electric current in a conductor.
Hertz then devised a wave detecting apparatus called a resonator.
Branly of Paris devised an appliance for detecting these waves which subsequently proved to be of immense importance.
As a scientific explanation of the myths the theory is of no value, but it affords fine scope for the exercise of Bacon's unrivalled power of detecting analogies in things apparently most dissimilar.
Many of these curious modifications may, it is true, be due to other causes than climate only, but they serve to show how powerfully and mysteriously local conditions affect the form and structure of both plants and animals; and they render it probable that changes of constitution are also continually produced, although we have, in the majority of cases, no means of detecting them.
Recourse is still had to dreams as a means of detecting, crime.
The definition of life must really be a description of the essential characters of life, and we must set out with an investigation of the characters of living substance with the special object of detecting the differences between organisms and unorganized matter, and the differences between dead and living organized matter.
For full accounts of methods used in detecting minute traces of arsenic in foods, &c., see "Report to Commission to Manchester Brewers' Central Association," the Analyst, 1900, 26, p. 8; "Report of Conjoint Committee of Society of Chemical Industry and Society of Public Analysts," the Analyst, 1902, 27, p. 48; T.
From the above instances we see that an instrumental appliance that polarizes a beam of light may be used as a means of detecting and examining polarization.
To this lofty quality of intellect he added a rare sagacity in perceiving analogies, and in detecting the new truths that lay concealed in his formulae, and a tenacity of mental grip, by which problems, once seized, were held fast, year after year, until they yielded up their solutions.
He thought his poetry too imitative, detecting not only the truthful severity of Crabbe, but a "slight bravura dash of the fair tuneful Hemans."
There is not much difficulty in detecting the difference tone by a resonator if it is held, say, close to the reeds of a harmonium, and Helmholtz succeeded in detecting the summation tone by the aid of a resonator.
