81. A History Of Hypercomplex Numbers 1867, hermann hankel (18391873) publishes Theory of complex numbers, containinga proof that complex numbers are the most general algebra that is possible http://history.hyperjeff.net/hypercomplex_slim.html

Back to the Full version Jeff Biggus Part of the HyperJeff Network Sketching the History of Hypercomplex Numbers last updated Monday, 14-Jan-2002 00:20:51 CST Brahmagupta (598-670) writes Khandakhadyaka which solves quadratic equations and allows for the possibility of negative solutions. pre Abraham bar Hiyya Ha-Nasi writes the work Hibbur ha-Meshihah ve-ha-Tishboret , translated in 1145 into Latin as Liber embadorum , which presents the first complete solution to the quadratic equation. Nicolas Chuquet (1445-1500) writes Triparty en la sciences des nombres . The fourth part of which contains the "Regle des premiers," or the rule of the unknown, what we would today call an algebra. He introduced an exponential notation, allowing positive, negative, and zero powers. In solving general equations he showed that some equations lead to imaginary solutions, but dismisses them ("Tel nombre est ineperible"). pre Nicolo Fontana (Tartaglia) finds the general method for solving all types of cubic equations and tells Cardano, under the promise that Cardano tell no one until he publishes first. Cardno tells everyone in 1545. Geronimo Cardano (1501-1576) writes Ars magna on the solutions of cubic and quartic equations. In it, solutions to polynomials which lead to square roots of negative quantities occur, but Cardano calls them "sophistic" and concludes that it is "as subtle as it is useless."

82. From Crossen To Adelaide hermanns brother Joseph Adolh Wilhelm Piltz came to SA in c1846 and married HuldaHankel also Josef Fedinand Hugo Piltz in the 1850s. hermann was farming in http://www.donicht.de/sedwardmcdonald.htm

From Crossen to Adelaide Carl August Hermann Piltz b:c1828 Crossen on Oder Brandenburg,was a carpenter and farmer,I do not as yet know of his parents details,but he came to Adelaide South Australia in 1851 on the ship "EMMY" Hamburg to Melbourne then to Adelaide,the captain was JHC Meyer and the surgeon recorded 28 deaths on arrival at Melbourne, the Ship was wrecked on the return voyage via India. Hermanns brother Joseph Adolh Wilhelm Piltz came to S.A in c:1846 and married Hulda Hankel also Josef Fedinand Hugo Piltz in the 1850s. Hermann was farming in Blumburg S.A with his relations and was married in 1856,where he was a carpenter by this time,in 1861 Hermann was natulized a British citizen so as to be able to purchase land,which he did and was licensee of the Barossa inn in Lobathnal 1862-63,he then again turned back to carpentry in Gawler S.A,his marriage produced two daughters Emmilie Mathilda 1856-1920(my GGGreatgrandmother) and Emma Hermine 1858-59. I have a lot of info' on the Piltz/Pilz clan and it has spread right across Australia into New South Wales and Queensland and many like myself decended from a female and so the name vanishes.

Inhalt Vorwort Marianne Schulz, Gleichstellungsbeauftragte für Frau und Mann Einweihung der Marie-Hankel-Straße Milou H. Obrecht, Urenkelin von Marie Hankel Straßennamen in Dresden – Reine Männersache? Nicole Schönherr, Frauenstadtarchiv Dresden Vorschlagsliste verdienstvoller Frauen für mögliche Straßenbenennungen in Dresden Biogramme Danksagung Bildnachweis, Quellen- und Literaturverzeichnis Vorwort In der offiziellen Geschichtsschreibung sind Frauen kaum erwähnt. Eine Würdigung ihrer Leistungen, ihres Wirkens, ihres Könnens bleibt somit aus. Geschichte ist jedoch immer eine Geschichte von Frauen und Männern, denn unzählige starke Frauen haben die Geschichte mit geprägt. Ehrung und Wertschätzung erfahren historische Persönlichkeiten u. a. durch die Benennung von Straßen und Plätzen mit ihrem Namen, so auch in Dresden. Doch selbst hierbei scheint sich der uralte Mythos vom schwachen Geschlecht hartnäckig zu halten. Dabei gibt es in der Dresdner Geschichte viele bemerkenswerte, verdienstvolle Frauen die Erwähnung und Würdigung verdienen. Unsere Recherche 2002 in Dresden ergab, dass 29 % der Straßen und Plätze in Dresden männlichen Persönlichkeiten, aber nur 3,3 % Frauen gewidmet wurden. Auf Grund von Eingemeindungen gibt es in der Stadt Dresden mehrfach Bezeichnungen von Straßen mit gleichem Namen. Kurz nach seinem Amtsantritt wies Oberbürgermeister Ingolf Roßberg darauf hin und legte fest, bei Neubenennung von Straßen vorrangig verdienstvolle Frauen zu berücksichtigen.
