paragraph_text: Denis Guedj (1940 – April 24, 2010) was a French novelist and a professor of the History of Science at Paris VIII University. He was born in Setif. He spent many years devising courses and games to teach adults and children math. He is the author of "Numbers: The Universal Language" and of the novel "The Parrot's Theorem". He died in Paris.

paragraph_text: The physics of quantum mechanics was thereby reduced to the mathematics of Hilbert spaces and linear operators acting on them. For example, the uncertainty principle, according to which the determination of the position of a particle prevents the determination of its momentum and vice versa, is translated into the non-commutativity of the two corresponding operators. This new mathematical formulation included as special cases the formulations of both Heisenberg and Schrödinger. When Heisenberg was informed von Neumann had clarified the difference between an unbounded operator that was a Self-adjoint operator and one that was merely symmetric, Heisenberg replied "Eh? What is the difference?"

paragraph_text: Prometheus Unbound is a four-act lyrical drama by Percy Bysshe Shelley, first published in 1820. It is concerned with the torments of the Greek mythological figure Prometheus, who defies the gods and gives fire to humanity, for which he is subjected to eternal punishment and suffering at the hands of Zeus. It is inspired by the classical "Prometheia", a trilogy of plays attributed to Aeschylus. Shelley's play concerns Prometheus' release from captivity, but unlike Aeschylus' version, there is no reconciliation between Prometheus and Jupiter (Zeus). Instead, Jupiter is abandoned by his supportive elements and falls from power, which allows Prometheus to be released.

paragraph_text: Guy Pearce reprises his role as Peter Weyland, the trillionaire founder and CEO of Weyland Corporation (now the Weyland - Yutani Corporation) who died before the destruction of the Prometheus. Noomi Rapace had played archaeologist Dr. Elizabeth Shaw as a member of the destroyed Prometheus in the prequel film, and appeared in a short promotional prologue to Covenant that was set in the period between the two movies, but does not act in the final cut of the movie itself, though her voice is heard and image seen. Andrew Crawford portrays the role of a neomorph, while Goran D. Kleut portrays the roles of both neomorph and xenomorph. Lorelei King portrays the voice of the Covenant's computer ``Mother ''; she was a colleague of Helen Horton, the voice of the Nostromo's`` Mother'' from 1979's Alien.

paragraph_text: Percy Bysshe Shelley ( ; 4 August 17928 July 1822) was one of the major English Romantic poets, who is regarded by some as among the finest lyric and philosophical poets in the English language, and one of the most influential. A radical in his poetry as well as in his political and social views, Shelley did not see fame during his lifetime, but recognition of his achievements in poetry grew steadily following his death. Shelley was a key member of a close circle of visionary poets and writers that included Lord Byron, John Keats, Leigh Hunt, Thomas Love Peacock and his own second wife, Mary Shelley, the author of "Frankenstein".

Dostoevsky died less than four months after its publication.

paragraph_text: A monstrous, mutated Fifield returns to the Prometheus and kills several crew members before he is killed. The Prometheus' captain, Janek, speculates that the structure was an Engineer military base that lost control of a virulent biological weapon, the dark liquid. He also determines that the structure houses a spacecraft. Weyland and a team return to the structure, accompanied by Shaw. David wakes the Engineer from stasis and speaks to him in an attempt to explain what Weyland wants. The Engineer responds by decapitating David and killing Weyland and his team, before reactivating the spacecraft. Shaw flees and warns Janek that the Engineer is planning to release the liquid on Earth, convincing him to stop the spacecraft. Janek and the remaining crew sacrifice themselves by ramming the Prometheus into the alien craft, ejecting the lifeboat in the process, while Vickers flees in an escape pod. The Engineer's disabled spacecraft crashes onto the ground, killing Vickers. Shaw goes to the lifeboat and finds her alien offspring is alive and has grown to gigantic size. David's still-active head warns Shaw that the Engineer is pursuing her. The Engineer forces open the lifeboat's airlock and attacks Shaw, who releases her alien offspring onto the Engineer; it thrusts an ovipositor down the Engineer's throat, subduing him. Shaw recovers David's remains, and with his help, launches another Engineer spacecraft. She intends to reach the Engineers' homeworld in an attempt to understand why they wanted to destroy humanity.

He served briefly as a colonial surveyor but left after a few years to rejoin the army. He died while in the service in Saugor, Bengal, India at 39.

paragraph_text: The punishment of Prometheus as a consequence of the theft is a major theme of his mythology, and is a popular subject of both ancient and modern art. Zeus, king of the Olympian gods, sentenced the Titan to eternal torment for his transgression. The immortal Prometheus was bound to a rock, where each day an eagle, the emblem of Zeus, was sent to feed on his liver, which would then grow back overnight to be eaten again the next day. (In ancient Greece, the liver was often thought to be the seat of human emotions). In some stories, Prometheus is freed at last by the hero Heracles (Hercules).

paragraph_text: Pandora ( pan-DOR-ə; Greek: Πανδώρα) is an inner satellite of Saturn. It was discovered in 1980 from photos taken by the Voyager 1 probe, and was provisionally designated S/1980 S 26. In late 1985 it was officially named after Pandora from Greek mythology. It is also designated as Saturn XVII.Pandora was thought to be an outer shepherd satellite of the F Ring. However, recent studies indicate that it does not play such a role, and that only Prometheus, the inner shepherd, contributes to the confinement of the narrow ring. It is more heavily cratered than nearby Prometheus, and has at least two large craters 30 kilometres (19 mi) in diameter. The majority of craters on Pandora are shallow as a result of being filled with debris. Ridges and grooves are also present on moon's surface.The orbit of Pandora appears to be chaotic, as a consequence of a series of four 118:121 mean-motion resonances with Prometheus. The most appreciable changes in their orbits occur approximately every 6.2 years, when the periapsis of Pandora lines up with the apoapsis of Prometheus and the moons approach to within about 1,400 kilometres (870 mi). Pandora also has a 3:2 mean-motion resonance with Mimas.From its very low density and relatively high albedo, it seems likely that Pandora is a very porous icy body. There is a lot of uncertainty in these values, however, so this remains to be confirmed.

paragraph_text: Baruch Hirson (10 December 1921 – 3 October 1999) was a South African political activist, academic, author and historian, who was jailed for nine years in apartheid-era South Africa before moving to England in 1973.

The episode was nominated for seven awards at the 1998 Emmys and won one. The entry generally received positive reviews; some reviewers called it a classic, with others calling it the most striking stand-alone episode of the show's fifth season.

paragraph_text: Then, in 1997, an almost complete Australopithecus skeleton with skull was found in the Sterkfontein caves of Gauteng, South Africa. It is now called ``Little Foot ''and it is probably around three million years old. It was named Australopithecus prometheus which has since been placed within A. africanus. Other fossil remains found in the same cave in 2008 were named Australopithecus sediba, which lived 1.9 million years ago. A. africanus probably evolved into A. sediba, which some scientists think may have evolved into H. erectus, though this is heavily disputed.
