... collectively known generally as impressionists, though the word "plein-airist" - luminist - has been chosen sometimes by them and by their admirers. The neo-impressionists in pictorial principle do not differ from the impressionist. Their technical procedure is different, and based on an optical law which proves that pure primary colours, put alongside of each other in alternating small quantities, will give, at a certain distance, a freshness and sparkle of atmosphere not attained by the earlier technical methods of the impressionistic school, which does not in the putting on of the ...

... comes, that in nature itself the more the principle of law breaks forth, the more does the husk drop off, the phaenomena themselves become more spiritual and at length cease altogether in our consciousness. The optical phaenomena are but a geometry, the lines of which are drawn by light, and the materiality of this light itself has already become matter of doubt. In the appearances of magnetism all trace of matter is lost, and of the phaenomena of gravitation, which not a few among the most illustrious ...

Still suspicious of his good faith, I suggested, tentatively, that perhaps the discrepancies between the normal man's vision and the pictures on the wall were the result of intentional distortion on the part of the artists. At this the professor ...

Galilei (1564-1642) enlarged the Copernican system with the aid of the telescope; and the telescope was an outcome of the new study of optics which had been inspired in Roger Bacon and other medieval scholars by the optical works, directly founded on the Greek, of the Spanish Moors. Giordano Bruno still further enlarged the system; he pictured the universe boldly as an infinite ocean of liquid ether, in which the stars, with retinues ...

In our opinion the mighty Newton won the greatest honours in the development of the science of optics, inasmuch as he was the first to connect and explain the vast mass of objective optical facts by a subjective and pregnant hypothesis. But, according to Virchow's view, Newton on the contrary transgressed greatly by teaching this erroneous hypothesis; for even in "exact" physics none but "independent and certain facts" are to be taught ...

... motionless above the earth. The telegraph poles traversing the plain in a long, straight line until lost to view in the hazy distance, appear to be suspended in mid-air; camels, horses, and all moving objects more than a mile away, present the strange optical illusion of animals walking through the air many feet above the surface of the earth. Long rows of kanaat mounds traverse the plain in every direction, leading from the numerous villages to distant mountain chains. Descending one of the sloping cavernous ...

He determined to attack the "second inequality," i.e. the optical illusion caused by the earth's annual motion, but first revived an old idea of his own that for the sake of uniformity the sun, or as he preferred to regard it, the earth, should have an equant as well as the planets. From ...

So it is ...

A gray-green uniform that at a distance would fade into misty obscurity had been devised after exhaustive experiments by optical, dye and cloth experts co-operating with the military high command. These uniforms had been standardized and fitted for the millions of men enrolled in Germany's regular and reserve armies. Rifles, great pyramids of munitions, field kitchens, traveling post-offices, motor lorries, a network ...

Again did he glance at the optical instrument, with his mouth wide open; then, making a comical movement of distrust, he quickly departed whence he had come. When he had got fairly into his row-boat, he entered into a most animated conversation with his fellows, and, judging by his motions as he put his ...

Olszewski, and illustrated for the first time in public the liquefaction of oxygen and air, by means of apparatus specially designed for optical projection so that the actions taking place might be visible to the audience. Soon afterwards he constructed a machine from which the liquefied gas could be drawn off through a valve for use as a cooling agent, and he showed its employment for this purpose in connexion with some ...

If any distant world (which may be the case) are so far ahead of us Tellurians in optical resources as to see distinctly through their telescopes all that we do on earth, what is the grandest sight to which we ever treat them? St. Peter's at Rome, do you fancy, on Easter Sunday, or Luxor, or perhaps the Himalayas? Pooh! pooh! my friend: suggest ...

The subject of optics, his own especial study, is treated with greater fulness; he enters into the question of the anatomy of the eye besides discussing problems which lie more strictly within the province of optical science. In a word, the "Greater Work," to borrow the phrase of Dr. Whewell, is "at once the Encyclopedia and the Novum Organum of the thirteenth century." The whole of the after-works of Roger Bacon—and treatise after treatise ...

No, not even though, as I before said, the Squire had seen, just under his nose, a very long pair of soles inserted in the apertures—that sight had only confused and bewildered him, unaccompanied as it ought to have been with the trunk and face of Lenny Fairfield. Those soles seemed to him optical delusions, phantoms of the overheated brain; but now, catching hold of Stirn, while the Parson in equal astonishment caught hold of him—the Squire faltered out, "Well, this beats cock-fighting!

Right before us, on the flat island mentioned before, were several small single trees or shrubs, growing at different distances from each other, close to the shore, but some optical delusion had detached them from the land on which they stood, and they had the appearance of so many little vessels sailing along the coast of it.

Half the extreme breadth intercepted between the circle and oval was 429/100,000 of the radius, and he remembered that the "optical inequality" of Mars was also about 429/100,000. This coincidence, in his own words, woke him out of sleep; and for some reason or other impelled him instantly to try making the planet oscillate in the diameter of its epicycle ...
