Ann. Phys., 3. Folge, 45. - Leipzig, Verlag von Johann Ambrosius Barth, 1892, 8°, VIII, 824 pp., nebst 8 figurentafeln, Pappband d.Zt.; feines Expl. First printing of a famous paper in astrophysics. Lebedew argues, "that if a small-enough particle is placed near the sun, the attractive force of the sun's gravitation could be more than compensated for by the repulsive force from the light rays." Partington "Breakthroughs", 1892 A. "As early as 1891 Lebedev became seriously interested in the pressure of light. He turned his attention to the fact that since the force of gravity is proportional to the volume of a body whereas light pressure must be proportional to its surface, it may be asserted that in a particle of cosmic dust the forces of light pressure pushing the particle away from the sun will be equals to the force of gravity attracting it toward the sun. Lebedev used this theory to explain why comets'tails always point away from the sun." DSB Pyotr Nikolaevich Lebedev (1866-1912) was a Russian physicist. His name was also transliterated as Peter Lebedew and Peter Lebedev. Lebedev was a creator of first scientific school in Russia.

Clean and fine. First printing of Lebedew's importent paper which he presented at an international conference (1899), and in which he described his detection of the pressure of light."He was interested in the possibility that light might exert pressures. This had been predicted by Maxwell's equations and it was a handy explanation, for instance, for the fact that comet's tails always pointed generally away from the sun whether the comet was approaching the sun or receding. In 1901 (in the paper offered), using very light mirrors in a vacuum, Lebedew was actually able to observe and measure the pressure exerted by light, again confirmning Maxwell's theories, as well as providing a vehicle for Arrhenius' life-spores."(Asimov).Parkinson "Breakthroughs", 1899 C.

(22 x 14,5 cm). VIII, 876 S. Mit 2 gefalteten Tafeln. Moderner Halbleinwandband im Stil der Zeit. Erste Ausgabe. - "As early as 1891 Lebedev became seriously interested in the pressure of light. He turned his attention to the fact that since the force of gravity is proportional to the volume of a body whereas light pressure must be proportional to its surface, it may be asserted that in a particle of cosmic dust the forces of light pressure pushing the particle away from the sun will be equals to the force of gravity attracting it toward the sun. Lebedev used this theory to explain why comets' tails always point away from the sun. His hypothesis was considered correct until the discovery of the solar wind, which creates substantially greater pressure than the sun's light. Around 1898, Lebedev began experimental research on light pressure. Although its presence had been predicted by Maxwell's theory, it had not been detected experimentally before Lebedev. He first undertook research on the pressure of light on solid bodies. By extremely ingenious methods Lebedev succeeded in completely eliminating these side effects and not only detected the pressure of light but also measured it and showed the correctness of Maxwell's quantitative theory. 'Opytnoe issledovanie svetovogo davlenia' ('An Experimental Investigation of the Pressure of Light') was read by Lebedev at the International Congress of Physicists at Paris in 1899 and was published in 1901" (DSB). - Titel verso gestempelt, sonst sehr sauber und wohlerhalten. - DSB 8, 106.
