A large board since MIT's founding, the Corporation has 60–80 members at any time, some with fixed terms, some with life appointments, and eight who serve ex officio . The Corporation approves

7178-409: The front. Somewhat later, an additional building to the rear (on San Gabriel Drive) was leased as a manufacturing/shipping area, bringing total square footage to 35,000. In February 1978, the company relocated to a 67,000-square-foot (6,200 m ) single-story building at 527 Lakeside Drive in Sunnyvale, part of the newly developed Oakmead Village industrial park. Additional buildings were added as

7275-641: The great majority of its courses available online for no charge, though without any formal accreditation for coursework completed. While the cost of supporting and hosting the project is high, OCW expanded in 2005 to include other universities as a part of the OpenCourseWare Consortium, which currently includes more than 250 academic institutions with content available in at least six languages. In 2011, MIT announced it would offer formal certification (but not credits or degrees) to online participants completing coursework in its "MITx" program, for

7372-593: The late 1990s. Calma Company was incorporated in California on November 13, 1963. Its initial business was as a product distributor, continuing the business of a previously existing partnership of the same name. The company took its name from its founders, Cal vin and Ir ma Louise Hefte. In 1965 Calma introduced the Calma Digitizer, a device consisting of a table-like surface with constrained cursor, whereby an operator could enter coordinate data from

7469-548: The men participated in fraternities and 20% of the women were involved in sororities. Most FSILGs are located across the river in Back Bay near where MIT was founded, and there is also a cluster of fraternities on MIT's West Campus that face the Charles River Basin. After the 1997 alcohol-related death of Scott Krueger, a new pledge at the Phi Gamma Delta fraternity, MIT required all freshmen to live in

7566-446: The most popular department, collectively identify themselves as "Course 6". MIT students use a combination of the department's course number and the number assigned to the class to identify their subjects; for instance, the introductory calculus-based classical mechanics course is simply "8.01" (pronounced eight-oh-one ) at MIT. The four-year, full-time undergraduate program maintains a balance between professional majors and those in

7663-439: The most powerful university-based nuclear reactors in the United States. The prominence of the reactor's containment building in a densely populated area has been controversial, but MIT maintains that it is well-secured. MIT Nano, also known as Building 12, is an interdisciplinary facility for nanoscale research. Its 100,000 sq ft (9,300 m ) cleanroom and research space, visible through expansive glass facades,

7760-702: The names of important scientists and philosophers. The spacious Building 7 atrium at 77 Massachusetts Avenue is regarded as the entrance to the Infinite Corridor and the rest of the campus. Alvar Aalto 's Baker House (1947), Eero Saarinen 's MIT Chapel and Kresge Auditorium (1955), and I.M. Pei 's Green , Dreyfus, Landau, and Wiesner buildings represent high forms of post-war modernist architecture . More recent buildings like Frank Gehry 's Stata Center (2004), Steven Holl 's Simmons Hall (2002), Charles Correa 's Building 46 (2005), and Fumihiko Maki 's Media Lab Extension (2009) stand out among

7857-478: The next five years. The acquisition was completed on April 1, 1981. GE had grander designs for Calma than had UTI. In addition to the hope of maintaining dominance in the IC market, GE aimed for Calma to expand in the architectural, engineering, manufacturing and construction markets – "factory of the future" was a prominent slogan. Due partly to a mass exodus of talent after GE moved its own people into key management positions, partly due to excessive expectations,

7954-399: The order in which the buildings were built and their location relative (north, west, and east) to the original center cluster of Maclaurin buildings. Many of the buildings are connected above ground as well as through an extensive network of tunnels, providing protection from the Cambridge weather as well as a venue for roof and tunnel hacking . MIT's on-campus nuclear reactor is one of

8051-556: The pace of life at the Institute" to match the return to peacetime, remembering the "academic tranquility of the prewar years", though acknowledging the significant contributions of military research to the increased emphasis on graduate education and rapid growth of personnel and facilities. The faculty doubled and the graduate student body quintupled during the presidential terms of Karl Taylor Compton (1930–1948), James Rhyne Killian (1948–1957), and chancellor Julius Adams Stratton (1952–1957), whose institution-building strategies shaped

8148-597: The phrase "from RTL to GDSII" to imply that their system will take users from a high-level logic design to a completed integrated circuit layout ready for delivery to the mask vendor. In the mechanical area, the DDM (for "Design Drafting and Manufacturing") product was introduced in 1977. It was later extended, under the name "Dimension III", to address the architecture, engineering and construction (AEC) market. By 1983, these two products together accounted for 60% of Calma's revenue. Dimension III continued to be used as late as

8245-905: The preferences of the students themselves, diverse social atmospheres can be sustained in different living groups; for example, according to the Yale Daily News staff's The Insider's Guide to the Colleges, 2010 , "The split between East Campus and West Campus is a significant characteristic of MIT. East Campus has gained a reputation as a thriving counterculture." MIT also has 5 dormitories for single graduate students and 2 apartment buildings on campus for married student families. MIT has an active Greek and co-op housing system, including thirty-six fraternities , sororities , and independent living groups ( FSILGs ). As of 2015 , 98% of all undergraduates lived in MIT-affiliated housing; 54% of

8342-637: The protests. The student body, faculty, and administration remained comparatively unpolarized during what was a tumultuous time for many other universities. Johnson was seen to be highly successful in leading his institution to "greater strength and unity" after these times of turmoil. However six MIT students were sentenced to prison terms at this time and some former student leaders, such as Michael Albert and George Katsiaficas , are still indignant about MIT's role in military research and its suppression of these protests. ( Richard Leacock 's film, November Actions , records some of these tumultuous events. ) In

8439-629: The requirements of the customers' specific design or drafting application. Calma's systems enable customers to automate a wide variety of design and manufacturing processes which have previously been performed manually. The primary hardware components of a system are a central processing unit , operator stations and plotter outputs. Their GDS I and II software operated on Data General Corporation's Nova and Eclipse line of 16 bit mini Computers. Sketches or layouts of electronic system were first manually drawn on mylar or paper to scale and were placed on large backlit 48 by 60 inch table digitizers. Using

8536-674: The size of the student body increased to more than one thousand. The curriculum drifted to a vocational emphasis, with less focus on theoretical science. The fledgling school still suffered from chronic financial shortages which diverted the attention of the MIT leadership. During these "Boston Tech" years, MIT faculty and alumni rebuffed Harvard University president (and former MIT faculty) Charles W. Eliot 's repeated attempts to merge MIT with Harvard College's Lawrence Scientific School . There would be at least six attempts to absorb MIT into Harvard. In its cramped Back Bay location, MIT could not afford to expand its overcrowded facilities, driving

8633-526: The spring semester commencing in early February and ceasing in late May. MIT students refer to both their majors and classes using numbers or acronyms alone. Departments and their corresponding majors are numbered in the approximate order of their foundation; for example, Civil and Environmental Engineering is Course 1 , while Linguistics and Philosophy is Course 24 . Students majoring in Electrical Engineering and Computer Science (EECS),

8730-427: The successive terms of the more humanistically oriented presidents Howard W. Johnson and Jerome Wiesner between 1966 and 1980. MIT's involvement in military science surged during World War II . In 1941, Vannevar Bush was appointed head of the federal Office of Scientific Research and Development and directed funding to only a select group of universities, including MIT. Engineers and scientists from across

8827-593: The time of the 1978 acquisition by UTI, the largest shareholder was Calma board chairman Ronald D. Cone. He held 321,706 of Calma's 635,266 outstanding shares. In February 1977, Computervision (CV) filed suit in federal court over Calma's hiring of a group of 5 employees from CV in San Diego. (This group developed Calma's DDM product.) The CV suit against Calma and the five employees alleged breach of competition, breach of non-competition agreements , and interference with contractual relations. This draining lawsuit

8924-588: The war in Vietnam as well as guidance systems for nuclear missiles. The Union of Concerned Scientists was founded on March 4, 1969 during a meeting of faculty members and students seeking to shift the emphasis on military research toward environmental and social problems. MIT ultimately divested itself from the Instrumentation Laboratory and moved all classified research off-campus to the MIT Lincoln Laboratory facility in 1973 in response to

9021-457: Was a 3-dimensional wireframe computer-aided design application. In the mid-1980s, it was one of the top ten selling CAD packages on the market. By 2006, DDM continued to be supported by Parametric Technology Corporation [1] as "Dimension III". The General Motors Central Foundry Division (GM-CFD) had applied DDM to the design of castings and tooling for automotive components such as engine blocks , cylinder heads and steering knuckles . DDM

9118-494: Was conceived and, in its initial implementation, almost single-handedly built by Dr. Sukonick. The first GDS system was shipped in late 1971 to Intel . The growth of sales of GDS paralleled that of the nascent integrated circuit industry. By August 1976 there were 121 GDS systems installed at 70 companies including many Fortune 500 corporations including Motorola , International Telephone & Telegraph , Fairchild Semiconductor , and others. Of these, 43 were installed outside

9215-514: Was designed and constructed by a team of scientists from California Institute of Technology , MIT, and industrial contractors, and funded by the National Science Foundation . It was designed to open the field of gravitational-wave astronomy through the detection of gravitational waves predicted by general relativity . Gravitational waves were detected for the first time by the LIGO detector in 2015. For contributions to

9312-539: Was finally settled out of court in October 1979. In the UTI acquisition of Calma in 1978, 5% of the newly issued stock was held in escrow as a reserve pending the outcome of this litigation. As early as 1970, Calma occupied a building at 707 Kifer Road in Sunnyvale. Roughly 10,000 square feet (900 m ), the building consisted of a large warehouse/manufacturing area in the rear, with an office area of about 10 offices in

9409-579: Was run on Calma's proprietary dual-monitor workstation hardware connected to Data General Nova and later Digital VAX 11/780 -series computers. GM-CFD had DDM installations in Saginaw, MI , Pontiac, MI , Defiance, OH , Bedford, IN , Danville, IL and Massena, NY .
