Macsyma ( / ˈ m æ k s ɪ m ə / ; "Project MAC's SYmbolic MAnipulator") is one of the oldest general-purpose computer algebra systems still in wide use. It was originally developed from 1968 to 1982 at MIT 's Project MAC .
128-509: In 1982, Macsyma was licensed to Symbolics and became a commercial product. In 1992, Symbolics Macsyma was spun off to Macsyma, Inc., which continued to develop Macsyma until 1999. That version is still available for Microsoft 's Windows XP operating system. The 1982 version of MIT Macsyma remained available to academics and US government agencies, and it is distributed by the US Department of Energy (DOE). That version, DOE Macsyma,
256-500: A " Public Ivy ". Since its inaugural 1990 reputational survey, Times Higher Education has considered Berkeley to be one of the world's "six super brands" along with the University of Oxford and the University of Cambridge , Harvard University , MIT , and Stanford University . The 2010 United States National Research Council Rankings identified Berkeley as having the highest number of top-ranked doctoral programs in
384-404: A 36- bit word (divided up as 4 or 8 bits of tags, and 32 bits of data or 28 bits of memory address). Memory words were 44 bits, the additional 8 bits being used for error-correcting code (ECC). The instruction set was that of a stack machine . The 3600 architecture provided 4,096 hardware registers, of which half were used as a cache for the top of the control stack ; the rest were used by
512-541: A 3600 depending on the model and the revision of the Ivory chip. The Ivory instruction set was later emulated in software for microprocessors implementing the 64-bit Alpha architecture. The "Virtual Lisp Machine" emulator , combined with the operating system and software development environment from the XL machines, is sold as Open Genera. Sunstone was a processor similar to a reduced instruction set computer (RISC), that
640-478: A blue background with an imaginary yellow pen. The California Victory Cannon, placed on Tightwad Hill overlooking the stadium, is fired before every football home game, after every score, and after every Cal victory. First used in the 1963 Big Game, it was originally placed on the sidelines before moving to Tightwad Hill in 1971. The only time the cannon ran out of ammunition was during a game against Pacific in 1991, when Cal scored 12 touchdowns. The Cal Mic Men,
768-531: A cameo appearance in the movie Real Genius . The company was also referenced in Michael Crichton's novel Jurassic Park . Symbolics' Graphics Division was sold to Nichimen Trading Company in the early 1990s, and the S-Graphics software suite (S-Paint, S-Geometry, S-Dynamics, S-Render) ported to Franz Allegro Common Lisp on Silicon Graphics (SGI) and PC computers running Windows NT . Today it
896-453: A company to commercialize Macsyma. Pavelle had written many scientific papers using Macsyma. With the papers in hand, Pavelle and Moses approached several venture capital firms that showed interest in funding a Macsyma startup. With potential deals close to finalization, MIT suddenly decided that MIT personnel should not profit directly from MIT developments. In early 1982, Macsyma was licensed by MIT to Arthur D. Little , Inc. (ADL), which became
1024-548: A culvert upstream of the recreational complex at the mouth of Strawberry Canyon and passes beneath California Memorial Stadium before appearing again in Faculty Glade. It then runs through the center of the campus before disappearing underground at the west end of campus. The north fork appears just east of University House and runs through the glade north of the Valley Life Sciences Building,
1152-491: A custom Symbolics Hardware Design Language (HDL), addressed a 40-bit word (8 bits tag, 32 bits data/address). Since it only addressed full words and not bytes or half-words, this allowed addressing of 4 Gigawords (GW) or 16 gigabytes (GB) of memory; the increase in address space reflected the growth of programs and data as semiconductor memory and disk space became cheaper. The Ivory processor had 8 bits of ECC attached to each word, so each word fetched from external memory to
1280-520: A directory called MAXSRC . Symbolics Symbolics, Inc. , was a privately held American computer manufacturer that acquired the assets of the former company and continues to sell and maintain the Open Genera Lisp system and the Macsyma computer algebra system . The symbolics.com domain was originally registered on March 15, 1985, making it the first .com -domain in
1408-489: A hacker's software could remain free software . In this way, Symbolics played a key, albeit adversarial, role in instigating the free software movement . In 1983, a year later than planned, Symbolics introduced the 3600 family of Lisp machines. Code-named the "L-machine" internally, the 3600 family was an innovative new design, inspired by the CADR architecture but sharing few of its implementation details. The main processor had

#17327833116951536-540: A line of Lisp machines , single-user computers optimized to run the programming language Lisp . Symbolics also made significant advances in software technology, and offered one of the premier software development environments of the 1980s and 1990s, now sold commercially as Open Genera for Tru64 UNIX on the Hewlett-Packard (HP) Alpha . The Lisp Machine was the first commercially available workstation , although that word had not yet been coined. Symbolics
1664-581: A new center for computing and data science. For the 2020 fiscal year, Berkeley set a fundraising record, receiving over $ 1 billion in gifts and pledges, and two years later, it broke that record, raising over $ 1.2 billion. Officially named the "University of California, Berkeley" it is often shortened to "Berkeley" in general reference or in an academic context ( Berkeley Law , Berkeley Engineering , Berkeley Haas , Berkeley Public Health ) and to "California" or "Cal" particularly when referring to its athletic teams ( California Golden Bears ). In August 2022,
1792-646: A parallel variant of Lisp and, initially, was used primarily by the AI community, so the Symbolics Lisp machine was a particularly good fit as a front-end machine. For a long time, the operating system didn't have a name, but was finally named Genera around 1984. The system included several advanced dialects of Lisp. Its heritage was Maclisp on the PDP-10, but it included more data types, and multiple-inheritance object-oriented programming features. This Lisp dialect
1920-435: A print and online edition. Berkeley's FM student radio station , KALX , broadcasts on 90.7 MHz. It is run largely by volunteers, including both students and community members. Berkeley also features an assortment of student-run publications: There are ninety-four political student groups on campus, including MEChXA de UC Berkeley, Berkeley ACLU , Berkeley Students for Life, Campus Greens, The Sustainability Team (STEAM),
2048-400: A request from Richard Fateman, then a professor at UC Berkeley , MIT provided a temporary license for Macsyma code in 1979. This was almost immediately brought up on the new VAX-11/780 computer using a dialect of Maclisp, Franz Lisp , written by Fateman's group. MIT reluctantly licensed versions of VAX Macsyma from Berkeley to about 50 universities, starting with Caltech, under condition that
2176-702: A research facility and headquarters for the California Institute for Quantitative Biosciences , opened. Supported by a grant from alumnus James Simons , the Simons Institute for the Theory of Computing was established in 2012. In 2015, Berkeley and its sister campus, UCSF , established the Innovative Genomics Institute to develop CRISPR gene editing , and, in 2020, an anonymous donor pledged $ 252 million to help fund
2304-572: A royalty payment to ADL of 15% of Macsyma gross sales. This royalty led to speculation on the desire of MIT and ADL to see MACSYMA prosper. The development of Macsyma continued at Symbolics despite the fact that it was seen as a diversion from the sales of Lisp machines , which Symbolics considered to be their main business despite the fact that Macsyma sales and the leveraged sales of Lisp Machines reached 10% of overall sales at Symbolics within two years. Despite resistance from many in Symbolics, Macsyma
2432-682: A simplified version (at right), known simply as the Symbolics keyboard . The Symbolics keyboard featured the many modifier keys used in Zmacs, notably Control/Meta/Super/Hyper in a block, but did not feature the complex symbol set of the space-cadet keyboard. Also contributing to the 3600 series' success was a line of bit-mapped graphics color video interfaces, combined with extremely powerful animation software. Symbolics' Graphics Division, headquartered in Westwood, Los Angeles , California, near to

The traditional role comes from students holding megaphones and yelling, but now includes microphones, a dedicated platform during games, and the direction of the entire student section. Berkeley students are offered a variety of housing options, including university-owned or affiliated residences, private residences, fraternities and sororities, and cooperative housing (co-ops). Berkeley students, and those of other local schools, have
2688-532: A student regent, and a non-voting student regent-designate. Prior to 1952, Berkeley was the University of California, so the university president was also Berkeley's chief executive. In 1952, the university reorganized itself into a system of semi-autonomous campuses, with each campus having its own chief executive, a chancellor, who would, in turn, report to the president of the university system. Twelve vice-chancellors report directly to Berkeley's chancellor, and

#17327833116952816-612: A system of semi-autonomous campuses, with each campus given a chancellor, and Clark Kerr became Berkeley's first Chancellor, while Robert Sproul remained in place as the President of the University of California. Berkeley gained a worldwide reputation for political activism in the 1960s. In 1964, the Free Speech Movement organized student resistance to the university's restrictions on political activities on campus—most conspicuously, student activities related to
2944-543: A trustee of the College of California, suggested that a new campus site north of Oakland be named in honor of Anglo-Irish philosopher George Berkeley . The university began admitting women the following year. In 1870, Henry Durant , founder of the College of California, became its first president. With the completion of North and South Halls in 1873, the university relocated to its Berkeley location with 167 male and 22 female students. The first female student to graduate
3072-458: A university task force was formed which recommended renaming the athletic identity to "Cal Berkeley" to further tie the athletic brand to academic prestige, and reduce public confusion. The University of California is governed by a twenty-six member Board of Regents , eighteen of whom are appointed by the Governor of California to 12-year terms. The board also has seven ex officio members,

For example, a host name and a request for "Terminal Connection" might yield a connection over TCP/IP using the Telnet protocol (although there were many other possibilities). Likewise, requesting a file operation (such as a Copy File command) might pick NFS , FTP , NFILE (the Symbolics network file access protocol), or one of several others, and it might execute
3328-584: Is Oski the Bear , who debuted in 1941. Previously, live bear cubs were used as mascots at Memorial Stadium until it was decided in 1940 that a costumed mascot would be a better alternative. Named after the Oski-wow-wow yell, he is cared for by the Oski Committee, whose members have exclusive knowledge of the identity of the costume-wearer. The University of California Marching Band , which has served
3456-466: Is a current, free, open codebase that includes numerous additional features, several alternative front ends, and works with a number of Common Lisp engines. While this has resulted in some incompatibilities between Macsyma and Maxima, programs written in the Macsyma algebraic language can often be run, with only minor changes, in either system. ITS Macsyma from around 1982 is available, with most files in
3584-661: Is also home to the University of California Botanical Garden , with more than 12,000 individual species. What is considered the historic campus today was the result of the 1898 "International Competition for the Phoebe Hearst Architectural Plan for the University of California," funded by William Randolph Hearst 's mother and initially held in the Belgian city of Antwerp ; eleven finalists were judged again in San Francisco in 1899. The winner
3712-490: Is an important symbol of California school spirit. The Big "C" has its roots in an early 20th-century campus event called "Rush," which pitted the freshman and sophomore classes against each other in a race up Charter Hill that often developed into a wrestling match. It was eventually decided to discontinue Rush and, in 1905, the freshman and sophomore classes banded together in a show of unity to build "the Big C." Students invented

4480-673: The Civil Rights Movement . The arrest in Sproul Plaza of Jack Weinberg , a recent Berkeley alumnus and chair of Campus CORE , prompted a series of student-led acts of formal remonstrance and civil disobedience that ultimately gave rise to the Free Speech Movement, which movement would prevail and serve as a precedent for student opposition to America's involvement in the Vietnam War. In 1982,
4608-556: The Defense Advanced Research Projects Agency ( DARPA ) had invested heavily in AI solutions, severely damaged Symbolics. An internal war between Noftsker and the CEO the board had hired in 1986, Brian Sear, over whether to follow Sun's suggested lead and focus on selling their software, or to re-emphasize their superior hardware, and the ensuing lack of focus when both Noftsker and Sear were fired from

In early 1995 the company shipped Macsyma 2.0.5, with many improvements: On Wester's large test of symbolic math, Macsyma 2.0.5 scored 10% better than Maple and 15% better than Mathematica. Although Macsyma 2.0.5 was still very slow at numerics, it had a greatly strengthened portfolio of numerical analysis and linear algebra routines. (In 1996 Macsyma added LAPACK which greatly increased
6016-428: The 3600 family were popular for artificial intelligence (AI) research and commercial applications throughout the 1980s. The AI commercialization boom of the 1980s led directly to Symbolics' success during the decade. Symbolics computers were widely believed to be the best platform available for developing AI software. The LM-2 used a Symbolics-branded version of the complex space-cadet keyboard , while later models used

The initial Ivory processors were fabricated by VLSI Technology Inc in San Jose, California , on a 2 μm CMOS process, with later generations fabricated by Hewlett-Packard in Corvallis, Oregon , on 1.25 μm and 1 μm CMOS processes. The Ivory had a stack architecture and operated a 4-stage pipeline: Fetch, Decode, Execute and Write Back. Ivory processors were marketed in stand-alone Lisp Machines (the XL400, XL1200, and XL1201), headless Lisp Machines (NXP1000), and on add-in cards for Sun Microsystems (UX400, UX1200) and Apple Macintosh (MacIvory I, II, III) computers. The Lisp Machines with Ivory processors operated at speeds that were between two and six times faster than

Symbolics felt that they no longer had sufficient control over their product. At that point, Symbolics began using their own copy of the software, located on their company servers, while Stallman says that Symbolics did that to prevent its Lisp improvements from flowing to Lisp Machines, Inc. From that base, Symbolics made extensive improvements to every part of

8576-655: The commercial advantages of purpose-built Lisp machines. By 1995, the Lisp machine era had ended, and with it Symbolics' hopes for success. Symbolics continued as an enterprise with very limited revenues, supported mainly by service contracts on the remaining MacIvory, UX-1200, UX-1201, and other machines still used by commercial customers. Symbolics also sold Virtual Lisp Machine (VLM) software for DEC, Compaq, and HP Alpha-based workstations ( AlphaStation ) and servers ( AlphaServer ), refurbished MacIvory IIs, and Symbolics keyboards. In July 2005, Symbolics closed its Chatsworth, California , maintenance facility. The reclusive owner of

9216-400: The deans of the fifteen colleges and schools report to the executive vice chancellor and provost, Berkeley's chief academic officer. Twenty-three presidents and chancellors have led Berkeley since its founding. Presidents Chancellors With the exception of government contracts, public support is apportioned to Berkeley and the other campuses of the University of California system through
9344-513: The early 1980s. At the 3600's introduction, the smallest disk that could support the ZetaLisp software was 14 inches (360 mm) wide (most 3600s shipped with the 10½-inch Fujitsu Eagle ). The 3670 and 3675 were slightly shorter in height, but were essentially the same machine packed a little tighter. The advent of 8 inches (200 mm), and later 5 + 1 ⁄ 4 inches (130 mm), disk drives that could hold hundreds of megabytes led to
9472-658: The end of 2023, has raised over $ 6.2 billion. Berkeley is a large, primarily residential research university with a majority of its enrolment in undergraduate programs but also offering a comprehensive doctoral program. The university has been accredited by the Western Association of Schools and Colleges Senior College and University Commission since 1949. The university operates on a semester calendar and awarded 8,725 bachelor's, 3,286 master's or professional and 1,272 doctoral degrees in 2018–2019. There are 1,789 full-time and 886 part-time faculty members among
9600-507: The first TCP/IP implementations. It also supported DECnet and IBM's SNA network protocols. A Dialnet protocol used phone lines and modems . Genera would, using hints from its distributed namespace database (somewhat similar to Domain Name System (DNS), but more comprehensive, like parts of Xerox's Grapevine), automatically select the best protocol combination to use when connecting to network service. An application program (or
9728-542: The first implementation of the Hewlett-Packard Precision Architecture ( PA-RISC ). Symbolics' research and development staff (first at MIT, and then later at the company) produced several major innovations in software technology: The Symbolics Graphics Division (SGD, founded in 1982, sold to Nichimen Graphics in 1992) developed the S-Graphics software suite (S-Paint, S-Geometry, S-Dynamics, S-Render) for Symbolics Genera. This software
9856-842: The history of the western part of North America, with an emphasis on California, Mexico and Central America. The Bancroft Library also houses the Mark Twain Papers, the Oral History Center, the Center for the Tebtunis Papyri, and the University Archives. In his memoirs, Clark Kerr records Berkeley's rise in the rankings (according to the National Academies ) during the 20th century. The school's first ranking in 1906 placed it among
9984-410: The introduction of the 3640 and 3645, which were roughly the size of a two-drawer file cabinet. Later versions of the 3600 architecture were implemented on custom integrated circuits, reducing the five cards of the original processor design to two, at a large manufacturing cost savings and with performance slightly better than the old design. The 3650, first of the G machines , as they were known within
10112-549: The licenses would be revoked when negotiations for a proper license were complete. Indeed, this happened when the negotiation with Symbolics (see below) was complete. Symbolics was reluctant to license the VAX product, since VAX constituted competitive hardware to their own Lisp Machines and therefore suppressed the VAX software for five years. UC Berkeley also brought up copies of Macsyma on Motorola 68000 -based systems, most notably Sun workstations. Symbolics suppressed those as well. At
10240-686: The maintenance of the six Cal flags, the large California banner overhanging the Memorial Stadium Student Section and Haas Pavilion , the California Victory Cannon, Card Stunts and The Big "C" among other duties. The Rally Committee is also responsible for safekeeping of the Stanford Axe when it is in Cal's possession. Overlooking the main Berkeley campus from the foothills in the east, The Big "C"
10368-526: The major Hollywood movie and television studios, made its S-Render and S-Paint software into industry leaders in the animation business and its 24 fps lock displays were featured in Star Trek movies. Symbolics developed the first workstations able to process high-definition television (HDTV) quality video, which enjoyed a popular following in Japan. A 3600, with the standard black-and-white monitor, made
10496-425: The market momentum. Market share did not increase above 2%, because the competitors were entrenched in all key accounts, converting to a new product is very costly in learning time, and market growth declined. Also, starting in 1992 or 1993, Mathsoft engaged in a strategy of spending $ 10 million on direct mail at very low prices, which won much of the remaining growth in the symbolic math market, just when Macsyma Inc.
10624-523: The medical schools at the University of California, San Francisco and Stanford University . The university offers Master of Arts , Master of Science , Master of Fine Arts , and PhD degrees in addition to professional degrees such as the Juris Doctor , Master of Business Administration , Master of Public Health , and Master of Design . The university awarded 963 doctoral degrees and 3,531 master's degrees in 2017. Admission to graduate programs
10752-415: The mix of skills needed to add the kind of graphics, notebook interface and better numerics that Mathematica had. By 1989, it was clear to Petti that Symbolics would implode due to poor product strategy, and that it would take Macsyma with it. (Some product issues: (1) Symbolics' software was designed for MIT-class software developers without enough concessions to others. (2) Symbolics' world-class software
10880-559: The nation's first ROTC programs was established at Berkeley and its School of Military Aeronautics began training pilots, including Jimmy Doolittle . In 1926, future Fleet Admiral Chester W. Nimitz established the first Naval ROTC unit at Berkeley. Berkeley ROTC alumni include former Secretary of Defense Robert McNamara , Army Chief of Staff Frederick C. Weyand , sixteen other general officers , ten Navy flag officers , and AFROTC alumna Captain Theresa Claiborne . In
11008-426: The nation. Berkeley doctoral programs that received a #1 ranking included English, German, Political Science, Geography, Agricultural and Resource Economics, Mathematics, Physics, Chemistry, Biochemistry, Molecular Biology, Genetics, Genomics, Epidemiology, Plant Biology, Computer Science, Electrical Engineering, Mechanical Engineering, and Civil and Environmental Engineering. For Fall 2022, Berkeley's total enrollment
11136-1644: The next decade. Engelman and his staff left in 1969 to return to The MITRE Corporation . Some code came from earlier work, notably Knut Korsvold's simplifier. Later major contributors to the core mathematics engine were: Yannis Avgoustis ( special functions ), David Barton (solving algebraic systems of equations ), Richard Bogen ( special functions ), Bill Dubuque ( indefinite integration , limits, power series, number theory , special functions , functional equations, pattern matching , sign queries, Gröbner , TriangSys), Richard Fateman ( rational functions , pattern matching , arbitrary precision floating-point ), Michael Genesereth (comparison, knowledge database), Jeff Golden (simplifier, language, system), R. W. Gosper (definite summation , special functions , simplification, number theory ), Carl Hoffman (general simplifier, macros, non-commutative simplifier, ports to Multics and LispM , system, visual equation editor ), Charles Karney (plotting), John Kulp, Ed Lafferty ( ODE solution, special functions ), Stavros Macrakis ( real/imaginary parts , compiler, system), Richard Pavelle ( indicial tensor calculus , general relativity package, ordinary and partial differential equations ), David A. Spear ( Gröbner ), Barry Trager (algebraic integration, factoring , Gröbner ), Paul S. Wang (polynomial factorization and GCD , complex numbers , limits, definite integration , Fortran and LaTeX code generation), David Y. Y. Yun (polynomial GCDs ), Gail Zacharias ( Gröbner ) and Rich Zippel ( power series , polynomial factorization , number theory , combinatorics ). Macsyma
11264-596: The option of living in one of the twenty cooperative houses participating in the Berkeley Student Cooperative (BSC), a nonprofit housing cooperative network consisting of 20 residences and 1250 member-owners. About three percent of undergraduate men and nine percent of undergraduate women—or 3,400 of total undergraduates—are active in Berkeley's Greek system. University-sanctioned fraternities and sororities comprise over 60 houses affiliated with four Greek councils. The Associated Students of
11392-749: The original site of the Campus Arboretum. Trees in the area date from the founding of the university. The campus features numerous wooded areas, including: Founders' Rock , Faculty Glade, Grinnell Natural Area, and the Eucalyptus Grove, which is both the tallest stand of such trees in the world and the tallest stand of hardwood trees in North America. The campus sits on the Hayward Fault , which runs directly through California Memorial Stadium. The official university mascot
11520-445: The product issues, Petti tried in late 1988 to persuade Symbolics to adopt a software-only or board-level strategy; but the fourth president in four years would hear nothing of it. In 1990 Petti left Symbolics for a start-up. Macsyma, Inc., was founded in 1992 by Russell Noftsker (chairman, who had co-founded Symbolics ) and Richard Petti (president, who had turned around Macsyma for a time at Symbolics) by raising funds and purchasing
11648-530: The request over TCP/IP, Chaosnet, or whatever other network was most suitable. The most popular application program for the Symbolics Lisp Machine was the ICAD computer-aided engineering system. One of the first networked multi-player video games, a version of Spacewar , was developed for the Symbolics Lisp Machine in 1983. Electronic CAD software on the Symbolics Lisp Machine was used to develop
11776-440: The rights to Macsyma from the ailing Symbolics. Although the market was growing fast, Macsyma sales in 1991 and early 1992 were still falling rapidly. Macsyma's market share in symbolic math software had fallen from 70% in 1987 to 1% in 1992. By 1993, market growth had slowed and the market had standardized on Mathematica and Maple. The competitors had development staffs that were 4-8 times as large as that of Macsyma Inc. throughout
11904-524: The same reason.) Gold Hill Lisp was too unstable, and its weak architecture made it impossible for Gold Hill to eliminate the bugs. This was a crucial failure for Macsyma. It meant that Macsyma could not respond on PCs when Mathematica appeared on Apple computers in mid-1988. Macsyma appeared on Windows PCs in August 1989 using the CLOE Lisp from Symbolics. However, the Macsyma staff was too small and lacked
12032-574: The same time Fateman worked to change the (now revoked) temporary license for Macsyma into something more permanent. Ultimately, the United States Department of Energy imposed on MIT the requirement that they release a copy into the National Energy Software Center (NESC) library in 1982, while allowing MIT to assert restrictions in terms of high price and no redistribution. This was intended to protect
12160-510: The slower peripherals during normal operation. An Ethernet interface was standard equipment, replacing the Chaosnet interface of the LM-2. The 3600 was roughly the size of a household refrigerator. This was partly due to the size of the processor (the cards were widely spaced to allow wire-wrap prototype cards to fit without interference) and partly due to the size of disk drive technology in
12288-625: The software, and continued to deliver almost all the source code to their customers (including MIT). However, the policy prohibited MIT staff from distributing the Symbolics version of the software to others. With the end of open collaboration came the end of the MIT hacker community. As a reaction to this, Stallman initiated the GNU project to make a new community. Eventually, Copyleft and the GNU General Public License would ensure that
12416-611: The speed of most numerical linear algebra.) . The development team, at this time, included Jeff Golden (language, compiler, etc.), Bill Gosper (special functions, summation), Howard Cannon (user interface, optimization), and several consultants. Bill Dubuque worked on integration, equation solving, database, and optimization. Christopher Stacy and David H. Wood added MATLAB 's language and matrix functionality. Other developers made major contributions in numerical analysis, graphics, and help systems. The company could not continue indefinitely to outperform staffs 4-8 times as large and reverse
12544-523: The technology transfer to Symbolics. (Such restrictions have been since lifted, 2002 or so.) This so-called DOE Macsyma had been rewritten at MIT in a pre- Common Lisp dialect called NIL lisp , incompletely implemented on VAX/VMS , an unpopular system in academia, where Berkeley VAX Unix was common. DOE Macsyma formed the basis for the much-later open source Maxima system. In 1981, Moses and Richard Pavelle , an MIT staff member and proponent of applying Macsyma to engineering and science, attempted to form
12672-402: The time. Central processing unit (CPU) clock speed varied depending on which instruction was being executed, but was typically around 5 MHz. Many Lisp primitives could be executed in a single clock cycle . Disk input/output (I/O) was handled by multitasking at the microcode level. A 68000 processor (termed the front-end processor , (FEP)) started the main computer up, and handled
12800-435: The top six schools ("Big Six") in the nation. In 1934, it ranked second, tied with Columbia and the University of Chicago , behind only Harvard ; in 1957, it was ranked as the only school second to Harvard. In 1964, Berkeley was named the "best balanced distinguished university", meaning the school had not only the most top departments but also the highest percentage of top ranking departments in its school. The school in 1993
12928-541: The university also owns land to the northwest of the main campus, a married student housing complex in the nearby town of Albany ("Albany Village" and the "Gill Tract"), and a field research station several miles to the north in Richmond, California . The campus is home to several museums including the University of California Museum of Paleontology , the Berkeley Art Museum and Pacific Film Archive , and
13056-538: The university is also a producer of Rhodes Scholars , Marshall Scholars , and Fulbright Scholars . Made possible by President Lincoln 's signing of the Morrill Act in 1862, the University of California was founded in 1868 as the state's first land-grant university, inheriting the land and facilities of the private College of California and the federal-funding eligibility of a public agricultural, mining, and mechanical arts college. The Organic Act states that
13184-626: The university since 1891, performs at every home football game and at select road games as well. A smaller subset of the Cal Band, the Straw Hat Band, performs at basketball games, volleyball games, and other campus and community events. The UC Rally Committee, formed in 1901, is the official guardian of California's Spirit and Traditions. Wearing their traditional blue and gold rugbies, Rally Committee members can be seen at all major sporting and spirit events. Committee members are charged with
13312-421: The university's academic enterprise which is organized into fifteen colleges and schools that comprise 180 departments and 80 interdisciplinary units offering over 350 degree programs. Colleges serve both undergraduate and graduate students, while schools are generally graduate only, though some offer undergraduate majors or minors: The four-year, full-time undergraduate program offers 107 bachelor's degrees across
13440-561: The upscale residential neighborhoods of the Berkeley Hills . Immediately southeast of campus lies fraternity row and beyond that the Clark Kerr Campus and an upscale residential area named Claremont . The area south of the university includes student housing and Telegraph Avenue , one of Berkeley's main shopping districts with stores, street vendors and restaurants catering to college students and tourists. In addition,
13568-455: The west of the central campus is the downtown business district of Berkeley ; to the northwest is the neighborhood of North Berkeley, including the so-called Gourmet Ghetto , a commercial district known for high quality dining due to the presence of such world-renowned restaurants as Chez Panisse . Immediately to the north is a quiet residential neighborhood known as Northside with a large graduate student population; situated north of that are
13696-580: The world. In August 2009, it was sold to napkin.com (formerly XF.com) Investments. Symbolics, Inc. was a computer manufacturer headquartered in Cambridge, Massachusetts , and later in Concord, Massachusetts , with manufacturing facilities in Chatsworth, California (a suburban section of Los Angeles ). Its first CEO, chairman, and founder was Russell Noftsker . Symbolics designed and manufactured
13824-486: Was 45,745: 32,831 undergraduate and 12,914 graduate students, with women accounting for 56% of undergraduates and 49% of graduate and professional students. It had 128,226 freshman applicants and accepted 14,614 (11.4%). Among enrolled freshman, the average unweighted GPA was 3.90. Berkeley's enrollment of National Merit Scholars was third in the nation until 2002, when participation in the National Merit program
13952-682: Was Frenchman Émile Bénard , who refused to personally supervise the implementation of his plan and the task was subsequently given to architecture professor John Galen Howard . Howard designed over twenty buildings, which set the tone for the campus up until its expansion in the 1950s and 1960s. The structures forming the "classical core" of the campus were built in the Beaux-Arts Classical style, and include Hearst Greek Theatre , Hearst Memorial Mining Building , Doe Memorial Library , California Hall, Wheeler Hall , Le Conte Hall, Gilman Hall, Haviland Hall, Wellman Hall, Sather Gate , and
14080-404: Was a ' strategic business unit ' that should be funded based on its performance and potential, not based on the prospects of the main workstation business. However, Symbolics cut the Macsyma headcount after this period of sharp growth; Symbolics tried to use Macsyma as a tiny cash cow to fund the losses of the workstation business that was 30 times its size. The greatest product weakness of Macsyma
14208-594: Was a spinoff from the MIT AI Lab , one of two companies to be founded by AI Lab staffers and associated hackers for the purpose of manufacturing Lisp machines. The other was Lisp Machines , Inc., although Symbolics attracted most of the hackers, and more funding. Symbolics' initial product, the LM-2, introduced in 1981, was a repackaged version of the MIT CADR Lisp machine design. The operating system and software development environment, over 500,000 lines,
14336-470: Was also used to create a few computer-animated movies and was used for some popular movies. University of California, Berkeley The University of California, Berkeley ( UC Berkeley , Berkeley , Cal , or California ) is a public land-grant research university in Berkeley, California , United States. Founded in 1868 and named after the Anglo-Irish philosopher George Berkeley , it
14464-457: Was an old technology that was not important for Lisp applications, so they declined to invest in it. Double-precision arithmetic in Macsyma (on a PC version) was about six times slower than Fortran. Also Macsyma's matrices were implemented as lists of lists, which cost another factor of perhaps 5–10 in speed for key algorithms. Macsyma did not have many of the basic algorithms of numerical linear algebra , such as LU decomposition . In 1987-88,
14592-690: Was called Lisp Machine Lisp at MIT. Symbolics used the name ZetaLisp. Symbolics later wrote new software in Symbolics Common Lisp , its version of the Common Lisp standard. In the late 1980s (2 years later than planned), the Ivory family of single-chip Lisp Machine processors superseded the G-Machine 3650, 3620, and 3630 systems. The Ivory 390k transistor VLSI implementation designed in Symbolics Common Lisp using NS,
14720-606: Was discontinued. For 2019, Berkeley ranked fourth in enrollment of recipients of the National Merit $ 2,500 Scholarship (132 scholars). 27% of admitted students receive federal Pell grants . Berkeley students are eligible for a variety of public and private financial aid. Inquiries are processed through the Financial Aid and Scholarships Office, although schools such as the Haas School of Business and Berkeley Law , have their own financial aid offices. Much of
14848-431: Was easily superior to these other packages in symbolic math. Pavelle ran the Macsyma division at Symbolics until early 1986. In the second half of 1986 Richard Petti became the manager of the Macsyma business to reduce the sales and avoid conflict with employees in Symbolics. Macsyma cut headcount but expanded its sales force and marketing, and focused its developers more on features that customers asked for. (For example,
14976-493: Was formed in 2005 and broadcasts online. It is run by students with a variety of backgrounds and majors. Since the mid-2010s, it has been a program of the ASUC . Berkeley's independent student-run newspaper is The Daily Californian . Founded in 1871, The Daily Cal became independent in 1971 after the campus administration fired three senior editors for encouraging readers to take back People's Park . The Daily Californian has both
15104-572: Was in 1874, admitted in the first class to include women in 1870. Beginning in 1891, Phoebe Apperson Hearst funded several programs and new buildings and, in 1898, sponsored an international competition in Antwerp , where French architect Émile Bénard submitted the winning design for a campus master plan. Although the University of California system does not have an official flagship campus , many scholars and experts consider Berkeley to be its unofficial flagship. It shares this unofficial status with
15232-475: Was its numerical analysis. Mastering symbolic math was a herculean task; but numerical capabilities were critical to get a piece of the much larger engineering and lower-end scientific markets. At MIT Macsyma had a link to the IMSL (now a product of Perforce Software ) numerical libraries, but this link was severed when Macsyma moved to Symbolics. Lisp developers at Symbolics generally believed that numerical analysis
15360-400: Was losing share in the market due to dependence on very high-cost hardware. (3) In moving to VLSI hardware in the mid-1980s, Symbolics converted from 36-bit word size to a 40-bit, without justification from the market for the enormous development cost of this change.) Macsyma could not assemble a buy-out team due to lack of cooperation from MIT. After keeping reasonably quiet since 1986 about
15488-520: Was maintained by Bill Schelter . Under the name of Maxima , it was released under the GPL in 1999, and remains under active maintenance. The project was initiated in July, 1968 by Carl Engelman , William A. Martin (front end, expression display, polynomial arithmetic) and Joel Moses (simplifier, indefinite integration : heuristic/Risch). Martin was in charge of the project until 1971, and Moses ran it for
15616-472: Was originally founded as part of the university. Berkeley was a founding member of the Association of American Universities and was one of the original eight " Public Ivy " schools. In 2021, the federal funding for campus research and development exceeded $ 1 billion. Thirty-two libraries also compose the Berkeley library system which is the sixth largest research library by number of volumes held in
15744-453: Was released for DEC VAX computers and Sun workstations using Berkeley's Franz Lisp in the early to mid 80s. However, problems at Symbolics over the sales of Macsyma on computers other than Symbolics' eventually led to the decline of Macsyma sales. In the first half of 1986, Macsyma revenues were lower than in the first half of 1985, in a growing industry. Wolfram 's SMP program and Waterloo Maple were growing at this time, although MACSYMA
15872-413: Was struggling to rebuild its world-class product. In 1999, Macsyma were acquired by Tenedos LLC , a holding company that previously had purchased Symbolics. The holding company has not re-released or resold Macsyma, but Macsyma continues to be distributed by Symbolics for Microsoft Windows versions up to Windows XP . There is also a GPL -licensed version, called Maxima , based on the 1982 version of
16000-549: Was the only remaining member of the original 1906 "Big Six", along with Harvard; in that year Berkeley ranked first. The American Council on Education , a private non-profit association, ranked Berkeley tenth in 1934. However, by 1942, private funding had helped Berkeley rise to second place, behind only Harvard, based on the number of distinguished departments. In 1985, Yale University admissions officer Richard Moll published Public Ivies: A Guide to America's Best Public Undergraduate Colleges and Universities which named Berkeley
16128-682: Was to be released shortly after the Ivory. It was designed by Ron Lebel's group at the Symbolics Westwood office. However, the project was canceled the day it was supposed to tape out. As quickly as the commercial AI boom of the mid-1980s had propelled Symbolics to success, the AI Winter of the late 1980s and early 1990s, combined with the slowdown of the Ronald Reagan administration's Strategic Defense Initiative , popularly termed Star Wars , missile defense program, for which
16256-584: Was written in Maclisp , and was, in some cases, a key motivator for improving that dialect of Lisp in the areas of numerical computing, efficient compilation and language design. Maclisp itself ran primarily on PDP-6 and PDP-10 computers, but also on the Multics OS and on the Lisp Machine architectures. Macsyma was one of the largest, if not the largest, Lisp programs of the time. In response to
16384-531: Was written in Lisp from the microcode up, based on MIT's Lisp Machine Lisp . The software bundle was later renamed ZetaLisp , to distinguish the Symbolics' product from other vendors who had also licensed the MIT software. Symbolics' Zmacs text editor, a variant of Emacs , was implemented in a text-processing package named ZWEI , an acronym for Zwei was Eine initially , with Eine being an acronym for Eine Is Not Emacs . Both are recursive acronyms and puns on
