- 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 and me. At our next meeting February 7-8, 2014,
at NKU, we will read two pieces of the work of Bernhard Riemann (1826-1866),
neither of which were published during his short life but both of which were
highly influential when they were published. They were both associated with
the reception of his Habilitation from Göttingen in 1854, one on the
problem of whether "arbitary functions" could be represented by
Fourier series, the other the text of his inaugural lecture on what constitutes
an
*n*-dimensional manifold from the perspective of differential geometry. - 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.
- David Pengelley (New Mexico State University) and I presented an MAA Minicourse,
*Study the Masters: Using Primary Historical Sources in Mathematics Teaching*, at the Joint Mathematics Meetings in Boston in early January, 2012. - I cochaired, with Amy Shell-Gellasch (Beloit College) and David Pengelley, a successful session of papers titled "Treasures from the Past: Using Primary Sources in the Classroom," at the Joint Mathematics Meetings in New Orleans on January 7, 2011.
- 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. I consider this experience a seminal one in establishing me as an historian of mathematics.
- 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. These translations are housed online at the Euler Archive.
- David Pengelley maintains a compendious website listing resources galore for the use of history (and original sources in particular) in the mathematics classroom.
- 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 Maya calendar site (maintained at the Maya World Studies Center in Mérida, Yucatán, México) has a good article on Mayan 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.
- 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 125 Mathematical Perspectives: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).

- 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 Pages, 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.

- HOMSIGMAA (the History of Mathematics Special Interest Group of the MAA): I am currently Chair of HOMSIGMAA.
- Ohio Section (I now act as the Section Archivist.) The Section is preparing for its Centennial celebration in 2015-2016.
- I helped to run a (very successful) MAA Ohio Section Summer Short Course during the summer of 2008 here at Xavier University along 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 and the 11 participants had a great time!
- The Ohio Section has put together a nice local resource called Ohio Masters of Mathematics, a collection of short biographies of noted personalities in the history of mathematics in Ohio.
- The American Mathematical Society
- The Math Forum
- Wolfram MathWorld is sponsored by Wolfram Research.
- The Online Encyclopedia of Integer Sequences, created by Neil Sloane, is one of the most incredible sites on the web. Look up any important sequence of integers and find out what it is and who has written about it. Also a neat way to determine the next term of the sequence!

- WVXU, was purchased from Xavier University by Cincinnati Public Radio in 2006. 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 the U.S. only through the internet. 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.

- The New York Times is the best source for news in the world, even if you don't live in the City.
