Question: The Pleasure of Finding Things Out and what lecture on nanotechnology are both authored by American physicist Richard Feynman?

Context paragraphs:
Nanotechnology in fiction: 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.

The Pleasure of Finding Things Out: 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.

Brownian ratchet: In the philosophy of thermal and statistical physics, the Brownian ratchet or Feynman-Smoluchowski ratchet is a thought experiment about an apparent perpetual motion machine first analysed in 1912 by Polish physicist Marian Smoluchowski and popularised by American Nobel laureate physicist Richard Feynman in a physics lecture at the California Institute of Technology on May 11, 1962, during his Messenger Lectures series The Character of Physical Law in Cornell University in 1964 and in his text "The Feynman Lectures on Physics" as an illustration of the laws of thermodynamics.  The simple machine, consisting of a tiny paddle wheel and a ratchet, appears to be an example of a Maxwell's demon, able to extract useful work from random fluctuations (heat) in a system at thermal equilibrium in violation of the second law of thermodynamics.  Detailed analysis by Feynman and others showed why it cannot actually do this.

Feynman's Lost Lecture: 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.

There's Plenty of Room at the Bottom: "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.

QED (play): QED is a play by American playwright Peter Parnell that chronicles significant events in the life of Nobel Prize-winning physicist Richard Feynman.  It presents scenes from a fictional day in Feynman's life, less than two years before his death, interweaving many strands from his biography, from the Manhattan project to the "Challenger" disaster inquiry to more personal topics such as the death of Feynman's wife and his own fight with cancer.  The play, which grew out of a collaboration between Parnell, actor Alan Alda, and director Gordon Davidson, premiered in 2001.  The original production, directed by Davidson and starring Alda as Feynman, was performed first at the Mark Taper Forum in Los Angeles and, from late 2001 to mid-2002, on Broadway.

Ralph Leighton: 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."

Joan Feynman: Joan Feynman (born March 31, 1927) is an American astrophysicist.  She has made important contributions to the study of solar wind particles and fields; sun-Earth relations; and magnetospheric physics.  In particular, Feynman is known for developing an understanding of the origin of auroras.  She is also known for creating a model that predicts the number of high-energy particles likely to hit a spacecraft over its lifetime, and for uncovering a method for predicting sunspot cycles.  Feynman is the younger sister of physicist Richard Feynman.

Quantum Man: Richard Feynman's Life in Science: Quantum Man: Richard Feynman's Life in Science is the eighth non-fiction book by the American theoretical physicist Lawrence M. Krauss.  The text was initially published on March 21, 2011 by W. W. Norton & Company. " Physics World" chose the book as Book of the Year 2011.  In this book, Krauss concentrates on the biography of the physicist Richard Feynman.

Feynman diagram: In theoretical physics, Feynman diagrams are pictorial representations of the mathematical expressions describing the behavior of subatomic particles.  The scheme is named after its inventor, American physicist Richard Feynman, and was first introduced in 1948.  The interaction of sub-atomic particles can be complex and difficult to understand intuitively.  Feynman diagrams give a simple visualization of what would otherwise be a rather arcane and abstract formula.  As David Kaiser writes, "since the middle of the 20th century, theoretical physicists have increasingly turned to this tool to help them undertake critical calculations", and so "Feynman diagrams have revolutionized nearly every aspect of theoretical physics".  While the diagrams are applied primarily to quantum field theory, they can also be used in other fields, such as solid-state theory.
