Margarete Kahn
Margarethe Kahn (known as Grete Kahn, also Margarete Kahn, born 27 August 1880, missing after deportation to Piaski, Poland on 28 March 1942) was a German mathematician and Holocaust victim. She was among the first women to obtain a doctorate in Germany. Her doctoral work was on the topology of algebraic curves. Life and work Margarethe Kahn was the daughter of Eschwege merchant and flannel factory owner Albert Kahn (1853–1905) and his wife Johanne (née Plaut, 1857–1882). She had an older brother Otto (1879–1932). Five years after the untimely death of his wife Johanne, their father married her younger sister Julie (1860–1934), with whom he had a daughter, Margaret's half-sister Martha (1888–1942). After attending elementary school from 1887, and the Higher School for Girls from 1889 to 1896, Kahn until 1904 took private lessons to prepare for her ''Abitur'', because few high schools for girls existed at that time in Hesse, Germany. In 1904 she was given permissi ...

Gymnasium (Germany)
''Gymnasium'' (; German plural: ''Gymnasien''), in the German education system, is the most advanced and highest of the three types of German secondary schools, the others being ''Hauptschule'' (lowest) and ''Realschule'' (middle). ''Gymnasium'' strongly emphasizes academic learning, comparable to the British sixth form system or with prep schools in the United States. A student attending ''Gymnasium'' is called a ''Gymnasiast'' (German plural: ''Gymnasiasten''). In 2009/10 there were 3,094 gymnasia in Germany, with students (about 28 percent of all precollegiate students during that period), resulting in an average student number of 800 students per school.Federal Statistical office of Germany, Fachserie 11, Reihe 1: Allgemeinbildende Schulen – Schuljahr 2009/2010, Wiesbaden 2010 Gymnasia are generally public, state-funded schools, but a number of parochial and private gymnasia also exist. In 2009/10, 11.1 percent of gymnasium students attended a private gymnasium. The ...

Propaedeutics
Propaedeutics or propedeutics (from Ancient Greek , ''propaídeusis'' 'preparatory education') is a historical term for an introductory course into an art or science. The etymology of propedeutics comprises the Latin prefix ''pro'', meaning earlier, rudimentary, or in front of, and the Greek ''paideutikós'', which means "pertaining to teaching". As implied by the etymology, propaedeutics may be defined more particularly as the knowledge necessary before, or for the learning of, a discipline, but not which is sufficient for proficiency. In medicine, the terms "propedeutics"/"propedeutic" specifically refers to the preliminary collection of data about a patient by observation, palpation, temperature measurement, etc., without specialized diagnostic procedures. The 1851 '' Encyclopaedia Americana'' writes that it is: ...a term used by the Germans to indicate the knowledge which is necessary or useful for understanding or practising an art or science, or which unfolds its nature and ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Klara Löbenstein
Klara Löbenstein (15 February 1883 – 10 June 1968) was a German mathematician. She was among the first women to obtain a doctorate in Germany. Her doctoral work was on the topology of algebraic curves. Life and work Löbenstein was born in Hildesheim, Prussia on 15 February 1883 to merchant Lehmann Löbenstein and his wife Sofie (née Schönfeld). In 1904, Löbenstein was given permission to take her ''Abitur'' at the Realgymnasium I '' Gymnasium'' in Hanover. Thus she belonged to a small group of talented young women in Germany at the beginning of the 20th century who were allowed to take the ''Abitur'' externally at boys' schools. Since Prussia began to allow women to formally attend university only from the winter semester of 1908–09, Löbenstein and her friend Margarete Kahn first attended the universities of Berlin and Göttingen as guest students. They studied mathematics, physics, and propaedeutics at Berlin and Göttingen. Löbenstein's field of expertise was al ...
