input: Frege matriculated at the University of Jena in the spring of 1869 as a citizen of the North German Confederation. In the four semesters of his studies he attended approximately twenty courses of lectures, most of them on mathematics and physics. His most important teacher was Ernst Karl Abbe (1840-1905; physicist, mathematician, and inventor). Abbe gave lectures on theory of gravity, galvanism and electrodynamics, complex analysis theory of functions of a complex variable, applications of physics, selected divisions of mechanics, and mechanics of solids. Abbe was more than a teacher to Frege: he was a trusted friend, and, as director of the optical manufacturer Carl Zeiss AG, he was in a position to advance Frege's career. After Frege's graduation, they came into closer correspondence. His other notable university teachers were Christian Philipp Karl Snell (1806-86; subjects: use of infinitesimal analysis in geometry, analytical geometry of planes, analytical mechanics, optics, physical foundations of mechanics); Hermann Karl Julius Traugott Schaeffer (1824-1900; analytical geometry, applied physics, algebraic analysis, on the telegraph and other electronic machines); and the philosopher Kuno Fischer (1824-1907; Kantian and critical philosophy). Starting in 1871, Frege continued his studies in Gottingen, the leading university in mathematics in German-speaking territories, where he attended the lectures of Rudolf Friedrich Alfred Clebsch (1833-72; analytical geometry), Ernst Christian Julius Schering (1824-97; function theory), Wilhelm Eduard Weber (1804-91; physical studies, applied physics), Eduard Riecke (1845-1915; theory of electricity), and Hermann Lotze (1817-81; philosophy of religion). Many of the philosophical doctrines of the mature Frege have parallels in Lotze; it has been the subject of scholarly debate whether or not there was a direct influence on Frege's views arising from his attending Lotze's lectures. In 1873, Frege attained his doctorate under Ernst Christian Julius Schering, with a dissertation under the title of "Ueber eine geometrische Darstellung der imaginaren Gebilde in der Ebene" ("On a Geometrical Representation of Imaginary Forms in a Plane"), in which he aimed to solve such fundamental problems in geometry as the mathematical interpretation of projective geometry's infinitely distant (imaginary) points. Frege married Margarete Katharina Sophia Anna Lieseberg (15 February 1856 - 25 June 1904) on 14 March 1887.

Question: Pinhead is a fictional character from the Hellraiser series, first appearing as an unnamed figure in the Clive Barker novella The Hellbound Heart. The name "Pinhead" is derived from a sobriquet given to him by the crew of the first Hellraiser film; he is first credited as such in Hellbound: Hellraiser II. Nearly thirty years after The Hellbound Heart was published, the character was given the designations the Hell Priest and the Cold Man in the sequels that followed, The Scarlet Gospels and Hellraiser: The Toll. Pinhead is one of the leaders of the Cenobites, formerly humans but transformed into creatures which reside in an extradimensional realm, who travel to Earth through a puzzle box called the Lament Configuration in order to harvest human souls.

Described by Doug Bradley as stronger than Jason Voorhees and Michael Myers, Pinhead is an extremely powerful being, and as such, has several supernatural abilities. His preferred method of attack is by summoning hooks and chains to mutilate victims, often pulling said victims in several directions to tear them apart. These chains are subject to his total mental control and he may direct them at will. The chains may even change shape after having attached to a victim. Pinhead is highly resistant to damage and direct assault, being able to resist both gunshots and futuristic energy weapons. His magic is also used for creating objects out of thin air, teleporting, creating explosions at distances and deceiving opponents with illusions. He is capable of creating other cenobites from both living and dead victims. In order to act in the physical world, Pinhead needs to have been purposely summoned through the Lament Configuration, though this in itself is not usually enough for Pinhead to target the puzzle-solver: in Hellbound: Hellraiser II, Pinhead stops the Cenobites from torturing an emotionally traumatised girl who was manipulated as a proxy into opening the Configuration, remarking "...it is not hands that call us, it is desire." In Hell on Earth, he temporarily eliminates these restraints when he is separated from the part of him that is Elliot Spencer, wreaking havoc indiscriminately upon every human subject he encounters until he is finally defeated when Spencer willingly merges with Pinhead once again, the combination binding Pinhead as Spencer keeps his extremes in check. During this incident his powers were apparently expanded beyond their normal limits allowing him to physically warp reality to his will. Pinhead at first has no memory of his human past, though is reminded of it in Hellbound: Hellraiser II, which results in what screenwriter Peter Atkins described as him being "spiritually weakened" and subsequently killed by the Chanard Cenobite.
