the logic tea

The Logic Tea is a series of talks on topics in philosophy, linguistics, mathematics, computer science and related fields of interest. In particular, it addresses the Masters of Logic and PhD candidates of the Institute for Logic, Language, and Computation.

The series covers a wide variety of topics reflecting the diverse and interdisciplinary character of the Institute. Speakers include members of the ILLC as well as guests from other universities and research institutions. The talks aim at being accessible to the entire ILLC audience.

Talks will last about one hour, tea and cookies are available. Afterwards you are cordially invited to a round of drinks and some snacks in the 'Cafe Polder' in Science Park.


For further information, for suggestions, or if you would like to give a presentation at the Logic Tea yourself, please send an email to Sirin Botan, Julian Schlöder, or Bonan Zhao.
