History of Mathematics in and for the Curriculum Notes and References (Part 1) 1. Websites a. Organisations and sources These are the most reliable sources for general information. The BSHM site contains links to other sites which are also good and reliable, and which contain more specialised information. The MacTutor site is the best for Biographies and summaries of Historical Topics. The HPM website provides international links and notices of research topics, projects, publications and other useful items. MathDL LOCI contains accounts of classroom practice and other items of interest. Generally the links to other sites from these sites are reliable and often contain much more information on the history of different subjects. British Society for the History of Mathematics (BSHM) exists to promote research into the history of mathematics and its use at all levels of mathematics education. The Society's Bulletin is published by Taylor and Francis, and carries a wide range of articles and reviews of interest to the history of mathematics and mathematics education communities. This link provides information about how to join the Society; this site also contains information about the Society and its history, its current activities, and various resources on the history of mathematics. http://www.dcs.warwick.ac.uk/bshm/ There is now a BSHM Education site: http://www.bshmeducation.org/education.html MacTutor History of Mathematics Archive http://www-history.mcs.st-and.ac.uk/history/ The most reliable source for biographies and discoveries of mathematicians, accounts of civilisations and cultural aspects, particular topics and many other items. History and Pedagogy (HPM) is the International Study Group on the Relations between History and Pedagogy of Mathematics affiliated to ICMI. Researchers in mathematics education, teachers, curriculum developers, mathematicians, and many historians of mathematics are members of the group. Amongst other things, HPM organises satellite meetings of the ICME conference. The site contains HPM Newsletters, notices of HPM meetings, and links to other sites of interest. http://www.clab.edc.uoc.gr/hpm/ Mathematical Sciences Digital Library (MathDL) is sponsored by the Mathematical Association of America. http://convergence.mathdl.org/jsp/index.jsp It has an on-line publication called LOCI with a subsection called CONVERGENCE a collection of resources for teaching mathematics using its history. http://convergence.mathdl.org/mathDL/23/ © Leo Rogers.

There are many, and it depends on interests and how specialised you want to get. I offer only two as examples. EUCLID This is David Joyce’s site at Clark University - everything you ever wanted to know about Euclid’s Elements with Java animations of the theorems. http://aleph0.clarku.edu/~djoyce/java/elements/toc.html ARCHIMEDES PALIMPSEST PROJECT Fascinating, exciting and ‘bang up to date’! Follow the history of the document, its recovery and the process of preparing it for examination. The subject of this website is a manuscript of extraordinary importance to the history of science, the Archimedes Palimpsest. This thirteenth century prayer book contains erased texts that were written several centuries earlier still. These erased texts include two treatises by Archimedes that can be found nowhere else, The Method and Stomachion. Listen to the video clip of Reviel Netz, the foremost world expert on the interpretation of Greek mathematical manuscripts, and share his excitement about the discovery of Archimedes’ original writing not seen for more than a thousand years! http://www.archimedespalimpsest.org/ c.

Golden Rules for studying the history of mathematics If you already have some research experience, then this next list may seem obvious, but if you look at ‘histories’ of mathematics you will find that they all have their faults - some more than others. a) Chronology versus History. Chronology is useful, but is not history. A time-ordered list of events is just the ‘raw material’ from which we start. The history begins when we fill in the ‘gaps’, and that’s where it gets really interesting. b) Credulity. Historical and mathematical material contains many errors. Some of it is repeating traditional beliefs without foundation, others from carelessness, ignorance, prejudice or chauvinism. Do not believe anything automatically. Check against other sources. c) Priorititis. The claim that “X did something first” is usually meaningless. There are ambiguities about what the ‘something’ is, and what is meant by ‘doing’ it. There are plenty of examples where we can find precursors to an idea. Nothing appears ‘out of the blue’, and there are often discoveries that have happened virtually simultaneously and independently of each other. d) The Solomon Syndrome Historians have often judged mathematics of the past as ‘right’ or ‘wrong’ by their own standards. Typical examples are where an author blames a historical figure for an ‘incorrect proof’ without understanding exactly what it was that the person was trying to ‘prove’. Other common errors have blamed past mathematicians for not having the ‘correct concept’ of something which we take for granted today. e) Speculation. If you can’t show why, how or what happened, don’t invent a reason. If you feel a need to say something, make sure the reader/listener knows you don’t know and that you are making a suggestion or giving a plausible reason. f) The Matthew Synrdome. Matthew’s Gospel says that ‘to those who have much, more shall be given’. The importance of well-known figures is often exaggerated because their work is more likely to have been preserved and investigated. Beware of the ‘halo effect’. Euler was not responsible for the whole of 18th century mathematics, as some might lead you to believe, and there is controversy over Cauchy’s role as the reviewer (and possible plagariser) of the work of Bolzano and Galois. g) Plagiarism. We need to be clear about our sources and reference everything. With the use of the internet, it is even more difficult to spot students’ use of un-referenced material. Wikipedia and similar places are not reliable, and while they might be used by some © Leo Rogers. Revised June 2009 Leo.Rogers@education.ox.ac.uk Oxford University 4 History of Mathematics in and for the Curriculum to gain information, must be checked against reliable printed sources (usually from reputable journals). Learning to use Google Scholar is an art in itself. (These rules are adapted from Ken May’s Bibliography and Research Manual of the History of Mathematics, Toronto 1973) 3. Books. There are many books on the history of mathematics around now, and it is sometimes difficult to find the best available. In general anything published before about 1970 does not reflect the new attitudes to historical research, nor the awareness of the contributions of non-European cultures. All general histories of mathematics have gaps and often you will have to go to more specialized texts to find what you want. At this moment I am suggesting only Five Principal General Reference Books. Others are not useless - we can learn from all of them, but keep in mind the list of caveats above. I have put Amazon prices if you want to buy - but look in your library first. 1. The best standard general History of Mathematics at the moment is: Katz, V. (1998) A History of Mathematics: An Introduction. Harlow, England and Reading Massechusets Addison Wesley This book includes mention of the important contributions of the indigenous cultures of other parts of the world, and of the important contributions of the Chinese, Indian, Mesopotamian and Egyptian civilizations. It brings us up to date with selected issues in 20th century mathematics. Amazon from £27. Get the full version not the short one. 2. A comprehensive source on all kinds of aspects of using historical material in schools and universities is: Fauvel, J. and van Maanen J. (2000) History in Mathematics Education: The ICMI Study. Dordrecht, Boston, London. Kluwer This contains pretty well all that was known about using history of in the mathematics classroom, from curriculum surveys, national approaches, political influence, philosophical and multicultural issues to research perspectives and examples of the use of original sources. I suggest you get hold of this if you can. Your library may have a copy - or get it on inter-library loan and photocopy the bits you want. You can get a used one from Amazon for about £40. Unfortunately this book is expensive, even though there is a paperback edition. It was intended for teachers, but few teachers have seen it. The problem is that Kluwer is well-known for being expensive, but unfortunately they won the publishing contract from ICMI for a whole series of mathematics education ‘studies’ which are all very expensive. The International Commission for Mathematics Instruction (ICMI) is the organizing body that supports mathematics teaching and research. 3. The latest Source Book of information on the latest research on Ancient Cultures. Katz, V. (ed) ( 2007) The Mathematics of Egypt, Mesopotamia, China, India and Islam: A Sourcebook. Four internationally renowned authors write on their own subjects of expertise. This is the real background for the ‘elementary’ mathematics taught in school: © Leo Rogers. Revised June 2009 Leo.Rogers@education.ox.ac.uk Oxford University 5 History of Mathematics in and for the Curriculum Arithmetic, practical geometry, proto-algebra and trigonometry. Amazon about £40. Princeton. Princeton University Press 4. A brand new and very different History of Mathematics Robson, E. and Stedall, J. (eds.) (2008) The Oxford Handbook Of the History of Mathematics. Oxford , OUP Naturally, this book has to be selective, but it is arranged in ‘themes’ rather than in chronological eras. This is a completely different approach to writing the history of mathematics. Geographies and Cultures: Global, Regional and Local. People and Practices: Lives, Practices and Presentations. Interactions and Interpretations: Intellectual, Mathematical and Historical. It deals with mathematics arising from cultural practices as well as the technical aspects of contemporary mathematics taught in schools and colleges. Together they deal with the mathematics of 5000 years, but without privileging the past three centuries, and an impressive range of periods and places with many points of cross-reference between chapters. The key mathematical cultures of North America, Europe, the Middle East, India, and China are all represented here as well as areas that are not often treated in mainstream history of mathematics, such as Russia, the Balkans, Vietnam, and South America. 5.An important source book for any one who is interested in the development of the mathematics at levels usually found in a university undergraduate course is: Stedall, J, (2008) Mathematics Emerging. Oxford, O.U.P. This book contains the resources, translations and commentaries of original mathematical works that were assembled and used for the Oxford University course on the History of Mathematics. Eighteen chapters span the usual topics in Calculation, The beginnings of the Calculus, Number Theory, Probability, Functions, Continuity, Algebra, Complex Analysis, and Foundations of Mathematics. Each of the sections contains samples of original texts, together with translations and valuable commentaries. © Leo Rogers. Revised June 2009 Leo.Rogers@education.ox.ac.uk Oxford University 6
