However, according to him, there is less duality, in the sense of opposition, than synthesis ( one is the limit of the other ) and the effort of synthesis is constant according to him, like in his first formula, in which the first member pertains to mechanics and the second to optics:

However, professional optics fabricators and large research groups test their mirrors with interferometers.

However, in optics one cannot measure the electric field directly as it oscillates much faster than any detector ’ s time resolution.

However, their speed is obtained by combining numerous computers which, individually, are still slower than optics.

However, only about 1 percent of the night sky is close enough to a natural guide star to use adaptive optics, so various methods to create artificial laser guide stars have been developed, including the sodium laser system developed by the Lawrence Livermore National Laboratory and used by the University of California's Lick and Keck observatories.

However, many have also held an unofficial but highly influential role as a political or campaign advisor to their husbands — both Mila Mulroney and Laureen Harper were considered their husbands ' " secret weapons ", whose instinctive sense of campaign optics proved invaluable to their husbands ' careers ; Harper, for example, was credited as the brains behind a public appearance in which her husband, Prime Minister Stephen Harper, appeared on stage at Ottawa's National Arts Centre to sing The Beatles ' " With a Little Help from My Friends ", which was widely perceived as softening the Prime Minister's somewhat stiff and autocratic public image.

However, his observations extended into many other departments, including researches on optics.

However the resolution handicap has begun to be overcome by adaptive optics, speckle imaging and interferometric imaging, as well as the use of space telescopes.

However, the active optics system of the NTT was able to correct that error without refiguring the mirror.

However, this star can be much fainter than is required for natural guide star adaptive optics, because it is only used to measure tip and tilt and all higher order distortions are measured with the laser guide star. This means that many more stars are suitable and a correspondingly larger fraction of the sky is accessible.

However, Maxwell's theory was unsatisfactory regarding the optics of moving bodies, and while he was able to present a complete mathematical model, he was not able to provide a coherent mechanical description of the aether.

However, in practice, the quality of the image generally depends on the quality of the optics ( lenses ) and viewing conditions, not on magnification.

However, scholarship indicates that this claim of priority is not so clear ; Leonhard Euler discussed the principle in 1744, and there is evidence that Gottfried Leibniz preceded both by 39 years.

However, the revolution must be preceded by organisations able to convince people of the anarchist communist alternative and method.

However, the release of the lingual closure is preceded by a raising of the closed glottis to increase the air pressure in the space between the glottis and the point of closure, resulting in a release with a characteristic popping sound.

However, like those who preceded him, Marty dies -- as a result of a self-inflicted gunshot under very bizarre comedic circumstances.

However WB-62 lists a different and rather interesting chronology – here Atrahasis is listed as a ruler of Shuruppak and gudug priest, preceded by his father Shuruppak who is in turn preceded by his father Ubara-Tutu.

However, she was preceded by El Aguila, Firebird, Living Lightning, Skin, Spider-Man 2099, White Tiger, Angela Del Toro, and La Bandera.

However, the later discovery of the photoelectric effect demonstrated that under different circumstances, light can behave as if it is composed of discrete particles.

However, it remains ambiguous whether the discovery predates arrival of Europeans because of the presence of a Patagonian Missionary Society mission station on Keppel Island, founded in 1856.

However, most chemists followed Kekulé's lead in pursuing and developing what some have called " classical " structure theory, which was modified after the discovery of electrons ( 1897 ) and the development of quantum mechanics ( in the 1920s ).

However, the reason for this correction to the partition function remained obscure until the discovery of quantum mechanics.

However, the Delft merchants had decided to keep the discovery secret and returned in 1615 to hunt for their own profit.

However, the discovery of the object 1996 PW, an asteroid in an orbit more typical of a long-period comet, suggests that the cloud may also contain rocky objects.

However host discovery or ping scanning or ping sweep is still a part of network scanning tools like nmap, as it may give basic evidence about the existence of a remote machine.

However immediately after his discovery he did not improve it, allegedly because of an agreement to spend the next five years developing the New York City electric light and power system.

However, recent DNA analysis and the discovery of a common ancestor has supported the view that they share a common lineage, and thus rabbits and rodents are now often referred to together as members of the superclass Glires.

However, the presence of man in the Lower Paleolithic is attested by the discovery of stone tools characteristic of Acheulean such as hand axes reported by Théodore Monod at the tip of Fann in the peninsula of Cap-Vert in 1938, or cleavers found in the south-east .< ref > Abdoulaye Camara et Bertrand Duboscq, La préhistoire dans le Sud-Est du Sénégal, Actes du 2 < sup > e </ sup > Colloque de Kédougou, 18 – 22 fév.

However, the influence of evolution on behavior has been of interest to biologists and philosophers since soon after the discovery of evolution itself.

However, tin and lead can be smelted by placing the ores in a wood fire, leaving the possibility that the discovery may have occurred by accident.

However, research indicates that open-source software does have a higher flaw discovery, quicker flaw discovery, and quicker turn around on patches.

However, the subsequent discovery of the Kuiper belt, and in particular of the object, which is larger than Pluto yet does not fit Bode's law, have further discredited the formula.

However, Faraday was the first to publish the results of his experiments and thus receive credit for the discovery.

However he soon reversed this rosy assessment, when on October 23, 1854, The Times of London published a report by explorer-physician John Rae of the discovery by Eskimos of the remains of the lost Franklin expedition along with unmistakable evidence of cannibalism among members of the party:
