Dear Scientist using Python, EuroSciPy 2013, the Sixth Annual Conference on Python in Science, takes place in Brussels on 21 - 24 August 2013. The conference features two days of tutorials followed by two days of scientific talks that start with our keynote speakers, Cameron Neylon and Peter Wang. The topics presented at EuroSciPy are very diverse, with a focus on advanced software engineering and original uses of Python and its scientific libraries, either in theoretical or experimental research, from both academia and the industry. The program includes contributed talks and posters. Submissions for talks and posters are welcome on our website (http://www.euroscipy.org/). Authors must use the web interface to submit an abstract to the conference. In your abstract, please provide details on what Python tools are being employed, and how. The deadline for submission is 28 April 2013. Until 31 March 2013, you can apply for a sprint session on 25 August 2013. Also, potential organizers for EuroSciPy 2014 are welcome to contact the conference committee.
