The 33rd ORESME meeting will be held on Fri-Sat, **January 31-February 1**, at Northern Kentucky University.

We will continue our consideration of the work of **Bernhard Riemann** by reading the following works:

*Foundations for a general theory of functions of a complex variable* (*Grundlagen für eine allgemeine Theorie der Functionen einer veränderlichen complexen Grösse*, Inauguraldissertation, Göttingen, 1851) [his dissertation, in which he introduces the concept of a Riemann surface];

*On the number of prime numbers less than a given quantity* (*Über die Anzahl der Primzahlen unter einer gegebenen Grösse*, Monatsberichte der Berliner Akademie, 1859.) [in which his celebrated zeta function is introduced, and the Riemann Hypothesis first stated].

The first of these papers also comes from the Baker/Christensen/Orde translation, while the second was posted online by David Wilkins at his website

http://www.emis.de/classics/Riemann/

which is devoted to the mathematical papers of Riemann.
