MAA Ohio Section 2008 Summer Short Course:

• I helped to run the (very successful) MAA Ohio Section Summer Short Course this summer, June 18-20, 2008, here at Xavier with Prof. David Pengelley (New Mexico State University). The course was entitled Study the Masters: Using Primary Historical Sources in Teaching and Research. Participants started work on individual projects creating classroom modules based on primary historical documents for teaching a nice variety of mathematical topics. David & I were really excited to be involved in it!

Courses of my design:

• MATH 125 Mathematical Perspectives: Strategies for Cooperation and Competition
• MATH 147 Calculus from an Historical Perspective

Stuff I'm really interested in professionally:

History of Mathematics

• I am cofounder (with Prof. Dan Curtin, Northern Kentucky University) of the Ohio River Early Sources in Mathematical Exposition (ORESME) Reading Group, a biannual seminar in the Cincinnati area that meets to read significant original sources in mathematics.  The ORESME home page is maintained by Prof. Curtin. ORESME has just celebrated its 10th anniversary!
• The MacTutor History of Mathematics Archive at St. Andrews, Scotland, is one of the neatest sites that exists on the Web.  It is a substantial compendium of all sorts of information about important mathematics and mathematicians of history.
• David Joyce at Clark University maintains a great page on the history of mathematics.
• I spent three weeks each during the summers of 1996 and 1997 at the Institute on History of Mathematics and Its Use in Teaching (IHMT) at American University in Washington, DC.  The Institute was organized under the auspices of the Mathematical Association of America and was funded by the NSF through their Undergraduate Faculty Enhancement program.
• Whenever I teach the History of Mathematics course here at Xavier, I arrange a field trip with my students to visit the Rare Book Collection at the University of Cincinnati. It houses a remarkably large number of old books of historical importance in mathematics. Our visit there is often the high point of the semester!
• One of my distinguished colleagues at the IHMT, Ed Sandifer (Western Connecticut State University), is a founding member of the Euler Society. One of the more exciting goals of the Society is to prepare English translations of as much of the mathematical opus of the great eighteenth century mathematician, Leonhard Euler; it just celebrated the tricentennial of Euler's birth in 2007.  These translations are housed online at the Euler Archive.
• David Calvis at Baldwin-Wallace College (Berea, OH) has a wonderful page of mathematics history stuff.
• David Wilkins of Trinity College, Dublin, maintains this nice page of historical resources.
• The International Study Group on the Relations Between History and Pedagogy of Mathematics, an affiliate of the International Commission on Mathematics Instruction, has a newsletter and annual meetings.
• The Canadian Society for the History and Philosophy of Mathematics has a very interesting web page.
• Jeff Miller's project on the earliest known uses of many mathematical terms is fascinating and under continuous revision.

Specific resources arranged chronologically

• An article by Don Allen on Babylonian mathematics.
• A very nice bibliography on Babylonian mathematics by Eleanor Robson at Oxford.
• Images of pages from some of the rare books in the Vatican collection of Greek mathematics.
• There are a number of sites devoted to Euclid's Elements, easily the most influential work in all of mathematics:
• Ralph Abraham maintains the Visual Elements of Euclid site.
• David Joyce maintains another site focued on the Elements of Euclid.
• A page devoted to Archimedes by Chris Rorres at Drexel University.
• The Maya calendar site (maintained at the Maya World Studies Center in Mérida, Yucatán, México) has a good article on Maya mathematics.

• Japanese sangaku (temple geometry problems) are exhibited at this page by Hiroshi Kotera. There is a related page showing how sangi are used to solve polynomial equations.
• The Biblioteca Nazionale Centrale and the Istituto e Museo di Storia della Scienza, both of Florence, Italy, and the Max Planck Institute for the History of Science in Berlin have prepared an electronic publication of the Ms. Gal. 72, a manuscript by Galileo Galilei.
• Andrew McNab at the University of Manchester (England) has put together a page devoted to Isaac Newton which he calls Newtonia.
• Biographies of Women Mathematicians are being prepared by students at Agnes Scott College.
• My colleague here at Xavier, Sheila Doran, has designed a course called (MATH 114) Women in Mathematics.
• A site with a number of resources on the history of computing is maintained by the Ancient Computing Machinery Project.
• An enormous collection of information  is housed at the Virtual Museum of Computing by Jonathan Bowen at the University of Reading (England).

Number Theory

• The Number Theory Web provides links to more than 1400 number theorists worldwide. Of special interest is their constantly updated New Listings page where one can learn about the latest news in the field.
• Check out the Prime Page, the prime source of information on prime numbers!  It is maintained by Chris Caldwell at the University of Tennessee at Martin.
• There is also an interesting page, designed by Chen Shuwen (at Jiang Xing Electronic Ltd., in Jiangmen City, Peoples' Republic of China) and mirrored at a server in France, on equal sums of like powers of integers.

• MUG, the Maple Users Group, is an invaluable resource.
• A comprehensive source of links to a lrge number of resources, packages, pages, etc. is kept by Alejandro Jakubi at his Maple on the Web page.

Libraries

• Xavier University Library's electronic catalog, Xplore.
• Washington Research Libraries Consortium (DC), which includes American University with its Artemas Martin Collection of mathematics books.
• The University of Michigan Library is one of the best in the country. When you telnet there, login with the word "mirlyn" (Thanks to Fred Rickey for this telnet link).
• The Robert H. Goddard Library at Clark University has a fine collection of late nineteenth-century mathematics.
• A collection of old mathematics books kept at Georgia Tech University.

Other cool stuff:

Bridge

• I participate in the Xavier Univerity Bridge Marathon, a 12-pair social party bridge game. We play 8 times a year, once a month, October to May; the October and May sessions are on campus and the others are at members' homes. Each meeting involves two tables (4 pairs) and 6 hands per table for a total of 18 hands.
• For the more adventurous, see the American Contract Bridge League home page.

Maps

• There are a few wonderful map resources on the Web.  My favorite is still MapBlast.  But GoogleMaps is quite nice.

Radio

• WVXU, was recently purchased from Xavier University by Cincinnati Public Radio.  Cincinnati Public Radio also runs WGUC, the home of classical music on radio in Cincinnati. WVXU provides NPR programming, including the news programs Morning Edition, Weekend Edition, and All Things Considered; also, Fresh Air, and Wait, Wait, Don't Tell Me.  It also carries Echoes and A Prarie Home Companion.
• The best radio for my taste, however, is available in Cincinnati only through the web.  It's the thrice-weekly radio show Late Junction, which plays eclectic classical, progressive, and world music late nights on Tuesdays, Wednesdays and Thursdays on BBC Radio 3.  I'm very glad that the BBC posts these shows for listening up to 7 days after the original broadcasts; that way I can get my weekly fix.

E-zines

• The New York Times is the best source for news in the world, even if you don't live in the City.
• I'll also provide a link to the Cincinnati Enquirer for you.

The Weather, etc.

• My wife claims that we spend $70 a month for cable just so that I can watch the Weather Channel.  She's right, almost.  Here's their forecast for the Cincinnati area.
