newton

Isaac Newton was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus.
In the Principia, Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of the equinoxes and other phenomena, eradicating doubt about the Solar System's heliocentricity. He demonstrated that the motion of objects on Earth and celestial bodies could be accounted for by the same principles. Newton's inference that the Earth is an oblate spheroid was later confirmed by the geodetic measurements of Maupertuis, La Condamine, and others, convincing most European scientists of the superiority of Newtonian mechanics over earlier systems.
































Anton Seitz was a German painter of the second half of the 19th century. He is known as a painter-genre painter, a representative of the Munich School of painting.
Seitz trained at the Nuremberg Art School in engraving, but after moving to Munich, he concentrated on domestic painting. His paintings depicted either individual characteristic figures or scenes with several actors. His subjects the artist mainly found in the everyday life of "little people".
In 1876 Seitz became a member of the Munich Academy of Fine Arts, already considered a leading master of Munich painting.


Johann Georg Meyer von Bremen was a German painter who specialized in Biblical, peasant and family scenes.
He is associated with the Düsseldorf school of painting. In 1841, Meyer opened a studio of his own, but moved to Berlin as his fame increased (1853).
