Kim Eric Drexler (born April 25, 1955) is an American engineer best known for popularizing the potential of molecular nanotechnology (MNT), from the 1970s and 1980s. His 1991 doctoral thesis at Massachusetts Institute of Technology was revised and published as the book ''Nanosystems: Molecular Machinery Manufacturing and Computation'' (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992. ==Life and work== K. Eric Drexler was strongly influenced by ideas on Limits to Growth in the early 1970s. His response in his first year at Massachusetts Institute of Technology was to seek out someone who was working on extraterrestrial resources. He found Gerard K. O'Neill of Princeton University, a physicist famous for a strong focus on particle accelerators and his landmark work on the concepts of space colonization. Drexler participated in NASA summer studies on space colonies in 1975 and 1976. He fabricated metal films a few tens of nanometers thick on a wax support to demonstrate the potentials of high performance solar sails. He was active in space politics, helping the L5 Society defeat the Moon Treaty in 1980. Besides working summers for O'Neill building mass driver prototypes, Drexler delivered papers at the first three Space Manufacturing conferences at Princeton. The 1977 and 1979 papers were co-authored with Keith Henson, and patents were issued on both subjects, vapor phase fabrication and space radiators. During the late 1970s, Drexler began to develop ideas about molecular nanotechnology (MNT). In 1979, he encountered Richard Feynman's provocative 1959 talk There's Plenty of Room at the Bottom. The term "nano-technology" had been coined by the Tokyo Science University professor Norio Taniguchi in 1974 to describe the precision manufacture of materials with nanometer tolerances, and Drexler unknowingly used a related term in his 1986 book ''Engines of Creation: The Coming Era of Nanotechnology'' to describe what later became known as molecular nanotechnology (MNT). In that book, he proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity. He also first published the term "grey goo" to describe what might happen if a hypothetical self-replicating molecular nanotechnology went out of control. He has subsequently tried to clarify his concerns about out-of-control self-replicators, and make the case that molecular manufacturing does not require such devices. Drexler holds three degrees from MIT. He received his B.S. in Interdisciplinary Sciences in 1977 and his M.S. in 1979 in Astro/Aerospace Engineering with a Master's thesis titled "Design of a High Performance Solar Sail System." In 1991 he earned a Ph.D. under the auspices of the MIT Media Lab (formally, the Media Arts and Sciences Section, School of Architecture and Planning). His Ph.D. work was the first doctoral degree on the topic of molecular nanotechnology and his thesis, "Molecular Machinery and Manufacturing with Applications to Computation," was published (with minor editing) as ''Nanosystems: Molecular Machinery, Manufacturing and Computation'' (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992. Drexler and Christine Peterson, at that time husband and wife, founded the Foresight Institute in 1986 with the mission of "Preparing for nanotechnology.” Drexler and Peterson ended their 21-year marriage in 2002. Drexler is no longer a member of the Foresight Institute. In March 2004 Drexler signed scientists' open letter in support of cryonics. In August 2005 Drexler joined Nanorex, a molecular engineering software company based in Bloomfield Hills, Michigan, to serve as the company's Chief Technical Advisor. Nanorex's nanoENGINEER-1 software was reportedly able to simulate a hypothetical differential gear design in "a snap". In 2006, Drexler married Rosa Wang, a former investment banker who works with Ashoka: Innovators for the Public on improving the social capital markets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「K.
