Question: Jacques Vallée, a computer scientist, author, ufologist and former astronomer, describes allegations of the Montauk Project as an outgrowth of stories about what experiment?
Context: Aaron Godfred a film director and producer from Alaska and is notable for his work on in the films "Little Blue Pill" and "John Dies at the End".  He is also the founder of Montauk Project Films. Two Sisters (Original title: Entre deux soeurs) is a 1991 animated short by Caroline Leaf, and produced for the National Film Board of Canada by Robert Forget, Yves Leduc, Dagmar Teufel and Jacques Vallée. Sputnik Observatory (SPTNK) is an educational non-profit organization dedicated to the study of contemporary culture.  SPTNK documents, archives and disseminates ideas that are shaping modern thought.  SPTNK is regarded for its Jonathan Harris - designed website that interconnects ideas shared by extraordinary minds in fields as diverse as quantum physics, mathematics, neuroscience, biology, economics, architecture, digital art, video games, computer science and music.  Conversations include such people as physicist Freeman Dyson, game designer Will Wright, venture capitalist Jacques Vallée, biologist Lynn Margulis, aerospace entrepreneur Robert Bigelow, architect Lars Spuybroek and computer scientist Vint Cerf. Jacques Vallée, Sieur Des Barreaux (16 December 15999 May 1673) was a French poet, born in Châteauneuf-sur-Loire.  His great-uncle, Geoffroy Vallée, had been hanged in 1574 for the authorship of a book called "Le Flau de la Joy".  His nephew appears to have inherited his scepticism, which on one occasion nearly cost him his life; the peasants of Touraine attributed to the presence of the unbeliever an untimely frost that damaged the vines, and proposed to stone him.  His authorship of the sonnet on "Penitence", by which he is generally known, has been disputed, notably by Voltaire. The Montauk Project: Experiments in Time by Preston B. Nichols and Peter Moon is the first book in a series detailing supposed time travel experiments at the Montauk Air Force Base at the eastern tip of Long Island as part of the Montauk Project. Brigitte Vallée (born June 6, 1950, in Courbevoie, Hauts-de-Seine, France) is a French mathematician and computer scientist.  She entered the École Normale Supérieure de Jeunes Filles in 1970, and received her PhD in 1986 at the University of Caen (Lattice reduction algorithms in small dimensions).  She is "Directrice de Recherche" at the French CNRS at Université de Caen, since 2001 and specialized in computational number theory and analysis of algorithms.  Amongst the algorithms she had studied are the celebrated LLL algorithm used for basis reductions in Euclidean lattice and the different Euclidean algorithms to determine GCD.  The main tool used to achieve her results is the so-called "dynamical analysis".  Loosely speaking, it is a mix between analysis of algorithms and dynamical systems.  Brigitte Vallée greatly contributed to develop this method. The Montauk Project is an alleged series of secret United States government projects conducted at Camp Hero or Montauk Air Force Station on Montauk, Long Island, for the purpose of developing psychological warfare techniques and exotic research including time travel.  Jacques Vallée describes allegations of the Montauk Project as an outgrowth of stories about the Philadelphia Experiment.  The history of the Montauk Project story is closely associated with — and often believed to originate in — by Preston Nichols. Jacques Fabrice Vallée (] ; born September 24, 1939) is a computer scientist, author, ufologist and former astronomer currently residing in San Francisco, California. Montauk Chronicles is a 2014 documentary film from filmmaker Christopher P. Garetano.  The film covers the alleged happenings in the Montauk Project conspiracy. The interdimensional hypothesis (IDH or IH), is an idea advanced by Ufologists such as Jacques Vallée that says unidentified flying objects (UFOs) and related events involve visitations from other "realities" or "dimensions" that coexist separately alongside our own.  It is an alternative to the extraterrestrial hypothesis (ETH).
Answer: the Philadelphia Experiment
