File:Sir Isaac Newton by Sir Godfrey Kneller.jpg|link=Isaac Newton (nonfiction)|1676: Isaac Newton summarized the state of development of his method of fluxions and power series in the "Epistola posterior," which he sent to Oldenburg to transmit to Leibniz.

||1851: William Lassell discovers the moons Umbriel, and Ariel, orbiting Uranus. Pic.

||1804: Wilhelm Eduard Weber born ... physicist and academic. Pic.

||1821: Mathematician Philipp Ludwig von Seidel born. He formulated the notion of uniform convergence. Pic: https://it.wikipedia.org/wiki/Philipp_Ludwig_von_Seidel ... AMA says 23 Oct.

||1825: Carl Anton Bjerknes born ... mathematician and physicist. Bjerknes' earlier work was in pure mathematics, but he is principally known for his studies in hydrodynamics. Pic.

||1830: Marianne North born ... biologist and painter.

||1847: James MacCullagh dies ... mathematician. His most important paper on optics, entitled "An essay towards a dynamical theory of crystalline reflection and refraction", describes a potential function for a dynamical theory for the transmission of light. MacCullagh found that a conventional potential function proportional to the squared norm of the displacement field was incompatible with known properties of light waves. In order to support only transverse waves, he found that the potential function must be proportional to the squared norm of the curl of the displacement field. No birth date. Pic.
