"There's Plenty of Room at the Bottom" was a lecture given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959.
 Feynman considered the possibility of direct manipulation of individual atoms as a more powerful form of synthetic chemistry than those used at the time.
 The talk went unnoticed and did not inspire the conceptual beginnings of the field.
 In the 1990s it was rediscovered and publicised as a seminal event in the field, probably to boost the history of nanotechnology with Feynman's reputation.
The Pleasure of Finding Things Out is a collection of short works from American physicist Richard Feynman, including interviews, speeches, lectures, and printed articles.
 Among these is his famous 1959 lecture "There's Plenty of Room at the Bottom", his report on the Space Shuttle "Challenger" disaster, and his speech on scientific integrity in which he coined the term "cargo cult science".
 The original forward was written by Freeman Dyson.
Synthetic molecular motors are molecular machines capable of continuous directional rotation under an energy input.
 Although the term "molecular motor" has traditionally referred to a naturally occurring protein that induces motion (via protein dynamics), some groups also use the term when referring to non-biological, non-peptide synthetic motors.
 Many chemists are pursuing the synthesis of such molecular motors.
 The prospect of synthetic molecular motors was first raised by the nanotechnology pioneer Richard Feynman in 1959 in his talk "There's Plenty of Room at the Bottom".
Tom Newman (23 March 1894 – 30 September 1943) was an English professional player of English billiards and snooker.
 He was born Thomas Edgar Pratt in Barton-on-Humber, Lincolnshire.
 He always appeared under the name Tom Newman when playing billiards or snooker and changed his name formally in 1919, shortly before his marriage that year.
Tom Newman, a graduate student at Stanford University in 1985, was one of the two people to meet one of a pair of challenges put forth by Nobel Prize-winning physicist Richard Feynman at the annual meeting of the American Physical Society in 1959, in a talk titled "There's Plenty of Room at the Bottom".
Ralph Leighton ( ; born 1949) is an American biographer, film producer, and friend of the late physicist Richard Feynman.
 He recorded Feynman relating stories of his life.
 Leighton has released some of the recordings as "The Feynman Tapes".
 These interviews became the basis for the books "Surely You're Joking, Mr. Feynman!
" and "What Do You Care What Other People Think?
", which were later combined into the hardcover anniversary edition "Classic Feynman: All the Adventures of a Curious Character".
 Leighton is an amateur drummer and founder of the group Friends of Tuva.
 In 1990 he wrote "Tuva or Bust!
 Richard Feynman's Last Journey."
Feynman's Lost Lecture: The Motion of Planets Around the Sun is a book based on a lecture by Richard Feynman.
 Restoration of the lecture notes and conversion into book form was undertaken by Caltech physicist David L. Goodstein and archivist Judith R. Goodstein.
 Feynman had given the lecture on the motion of bodies at Caltech on March 13, 1964, but the notes and pictures were lost for a number of years and consequently not included in "The Feynman Lectures on Physics" series.
 The lecture notes were later found, but unfortunately without the photographs of his illustrative chalkboard drawings.
 One of the editors, David L. Goodstein, stated that at first without the photographs, it was very hard to figure out what diagrams he was referring to in the audiotapes, but a later finding of his own private lecture notes made it possible to understand completely the logical framework with which Feynman delivered the lecture.
Biological engineering or bio-engineering (including biological systems engineering) is the application of concepts and methods of biology (and secondarily of physics, chemistry, mathematics, and computer science) to solve real-world problems related to life sciences or the application thereof, using engineering's own analytical and synthetic methodologies and also its traditional sensitivity to the cost and practicality of the solution(s) arrived at.
 In this context, while traditional engineering applies physical and mathematical sciences to analyze, design and manufacture inanimate tools, structures and processes, biological engineering uses primarily the rapidly developing body of knowledge known as molecular biology to study and advance applications of organisms and to create biotechnology.
 This may eventually include the possibility of biologically engineering machines and 3D printing that re-order matter at a molecular scale.
 Physicist Richard Feynman theorized about the idea of a "medical" use for these biological machines, introduced into the body, to repair or detect damages and infections.
 Feynman and Albert Hibbs suggested that it might one day be possible to (as Feynman put it) "swallow the doctor".
 The idea was discussed in Feynman's 1959 essay "There's Plenty of Room at the Bottom."
The Tomcats were a band from Perivale, England in the early to mid sixties.
 The founder members were Tom Newman (later founder of Virgin Records with Richard Branson, and producer of Mike Oldfield's "Tubular Bells"), Pete Cook (later luthier to John Entwistle, and creator of the 'Ned Callan' guitar range with Tom Newman), Allan James (later bass player with psychedelic band July with Newman and Jackson), and Chris Jackson, drummer - (The Devil Rides Out).
The use of nanotechnology in fiction has attracted scholarly attention.
 The first use of the distinguishing concepts of nanotechnology was "There's Plenty of Room at the Bottom", a talk given by physicist Richard Feynman in 1959.
 K. Eric Drexler's 1986 book "Engines of Creation" introduced the general public to the concept of nanotechnology.
 Since then, nanotechnology has been used frequently in a diverse range of fiction, often as a justification for unusual or far-fetched occurrences featured in speculative fiction.
