The Mathematical Laboratory
• Founded 1937, Sir MV Wilkes.• EDSAC ran first stored program 1949• Thenceforth provided a computer
service• Titan, IBM machines, Phoenix• Diploma started in 1953• Undergraduate Tripos in 1969• Moved to WGB in 2001• Rated 5* and ‘Excellent’
University of CambridgeComputer LaboratoryDJG 2004
1949: Edsac 1
University of CambridgeComputer LaboratoryDJG 2004
1977: Cambridge Distributed System
University of CambridgeComputer LaboratoryDJG 2004
1993: Autostereo Display

William Gates Building
• A split with the Computer Service
• All research under one roof
• Two lecture theatres, one practical laboratory.
• Intel, Optronics and LCE currently on top floor
• Microsoft MSR out the back in their own building.

Undergraduate Courses• 25% Computer Science (with 75%
maths)• 50% Computer Science (with 25% NST)• Full time for years 2 and 3 leading to
BA.• Part II General - A one year part II• Diploma - A masters-like conversion
course
University of CambridgeComputer LaboratoryDJG 2004
Admission
• Undergraduates admitted by Colleges• Admission requirements:
– A-level Maths– One other science A level (pref Further
Maths)– A third A-level or international equivalent
• Postgraduates (PhD) must find a supervisor who will has an interest in their research

What is Computer Science ?
• It is not how to use Microsoft Excel
• It is not how to design web sites
• It is not how to be an IT manager
• We don’t even train people in C++ programming.
• It is about theory of data representation
• It is about network protocol design
• It is about the history and future of operating systems
• It’s about fundamental differences between programming paradigms.
University of CambridgeComputer LaboratoryDJG 2004
Example CST Subject Areas
• Continuous Maths• Discrete Maths• Software Engineering• Programming• Operating Systems• Compilers• Databases• Information Theory
and Coding
• Computability• Semantics• Hardware• Processor Design• Business • Communications• Spec and Verification• VLSI
University of CambridgeComputer LaboratoryDJG 2004
3 year Tripos Practical Work
• Ia: Java ticks• Ia: ML ticks• Ia: Hardware ticks
• Ib: ECAD and Architecture ticks• Ib: Group Projects
• II: Project and Dissertation (25% marks).
University of CambridgeComputer LaboratoryDJG 2004
ML programming demo.• ML is the first language our students
see• It is functional (not imperative)• One of the most-advanced languages
ever becoming mainstream (almost mainstream).
• Aim to teach fundamentals, not arbitraryness.
– `If something has been known for 10 years and looks as though it will remain true for the next 10 years, then it’s probably worth teaching’ - RMN.

ML: Three Ways to Add Up(* Mathematician *)fun intsum1(a, b) = (b-a+1) *(a+b) div 2;
(* Engineer *)fun intsum3(a, b) = if (a=b) then a else
let val midpoint = (a+b) div 2in intsum3(a, midpoint) + intsum3(midpoint+1, b)end
;
(* Computer Scientist *)fun intsum2(a, b) = if (a = b) then a else a + intsum2(a+1, b);

Postgraduate Courses
• PhD in theoretical computer science– Can be in any area researched in the
department.
• 1986: M Phil in Speech and Language Processing (with dept of Engineering)
• Fourth Year in School of Technology ?– Currently being planned.
University of CambridgeComputer LaboratoryDJG 2004
Current Major Research Areas• Programming Languages, Compilers
• Security - Smart Cards, Trusted Computing• Systems - OS, Processors, Middleware,
Trust, Networks, H/W.• Rainbow - Graphics, HCI, Asynch H/W• Natural Language and Information

Supporter’s Club
• 10 to 50 Local Industry Fund Contributors
• Originally for local companies• Library and consultancy access• Frequently funds PhD Students• Specialist Lecture Series• Recruitment Fair Once a Year• Well-attended annual dinner!
University of CambridgeComputer LaboratoryDJG 2004
Women in Computer Science
• Sometimes seen as a male profession ?• WICS mission to redress balance.• Currently 4 or so female out of 30
lecturers.• Only 5 to 10 percent of undergraduates• 15 percent of postgraduates ?• WICS regular meetings, open agenda• Women frequently come top in Tripos.• 2002: 26.9% of the 52 female applicants to Cambridge
Computer Science were accepted compared to 21.6% of the 416 male.
University of CambridgeComputer LaboratoryDJG 2004
Graduate Association
• Recently established, 2002
• 200-300 members• Annual update and
dinner• Advice and consultancy• Should become self-
funding
• Called ‘The Cambridge Ring’
University of CambridgeComputer LaboratoryDJG 2004
Local Industry• 28,000 Hi-tech employees in Cambridge• 14,000 of them in computing/electronics• New companies are always being founded
