The Encyclopedia of Astrobiology, Astronomy, and Spaceflight FRONT PAGE NEWS ARCHIVE NEWSLETTER ... Z this site WWW Lambert, Johann Heinrich (1728-77) German philosopher, described by Immanuel Kant as "the greatest genius of Germany." Lambert also ranked among the leading astronomers, mathematicians, and physicists of his day. In his Cosmological Letters (1761) he arrived, independently, at much the same conclusion as Kant and Thomas Wright , concerning the disk-shaped form of the Milky Way and the existence of external systems of stars (galaxies) throughout space. Lambert's Letters which reached a wider audience in eighteenth century Europe than did the works of either Wright or Kant, is also replete with the most extreme kind of speculation about extraterrestrial life. No object in the universe, as far as Lambert was concerned, is devoid of life - and life, moreover, of every conceivable kind. "The Creator," he asserts in his Letters , "... is much too efficient not to imprint life, forces and activity on each speck of dust.... [I]f one is to form a correct notion of the world, one should set as a basis God's intention in its true extent to make the whole world inhabited ..." The principle of plenitude he adopts without restraint: "all possible varieties which are permitted by general laws ought to be realized ... " Yet Lambert is reasonable enough to acknowledge that he is being purely speculative: "And truly, have I not already rambled somewhat beyond the limits of what is credible? I drew conclusions. and surely enough without having in each case appropriate observational evidence on hand ..." Like Wright and Kant, Lambert was driven to his extraterrestrial conclusions by the conviction that God, in his omnipotence, could not fail to populate every corner of the cosmos with all manner of beings. Indeed, these three pioneers of galactic and extragalactic astronomy seem to have been motivated as much by their desire to expand the number of planetary systems available for habitation as they were to populate the heavens with more stars.

22. Quotations By Lambert Quotations by johann H lambert. Proofs of the Euclidean parallel postulatecan be developed to such an extent that apparently a mere trifle remains. http://www-gap.dcs.st-and.ac.uk/~history/Quotations/Lambert.html

Quotations by Johann H Lambert Proofs of the Euclidean [parallel] postulate can be developed to such an extent that apparently a mere trifle remains. But a careful analysis shows that in this seeming trifle lies the crux of the matter; usually it contains either the proposition that is being proved or a postulate equivalent to it. Quoted in C B Boyer, A History of Mathematics (New York 1968) I am undecided wheter or not the Milky Way is but one of countless others all of which form an entire system. Perhaps the light from these infinitely distant galaxies is so faint that we cannot see them.

Johann Heinrich Lambert Born: Died: 25 Sept 1777 in Berlin, Prussia (now Germany) Click the picture above to see three larger pictures Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Johann Lambert was a colleague of Euler and Lagrange at the Berlin Academy of Sciences. In 1766 Lambert wrote Theorie der Parallellinien which was a study of the parallel postulate . By assuming that the parallel postulate was false, he managed to deduce a large number of non-euclidean results. He noticed that in this new geometry the sum of the angles of a triangle increases as its area decreases. Lambert is best known, however, for his work on p Euler had already established in 1737 that e and e are irrational . Lambert was the first to provide a rigorous proof that p is irrational. In a paper presented to the Berlin Academy in 1768 Lambert showed that, if x is a nonzero rational number, then neither e x nor tan x can be rational. Since tan p /4 = 1 then p /4 must be irrational. Lambert conjectured that e and p are transcendental . This was not proved for another century when Hermite proved that e is transcendental and Lindemann proved that p is transcendental.
