The general colloquium will resume in September.

In addition to the General Mathematics Colloquium, there is a regular Seminarium Recreatieve Wiskunde (Dutch seminar on recreational mathematics), which is aiming at anybody interested in the recreational aspects of mathematics. The lectures of this seminar do not require a mathematical background.

The Instituut Lorentz (for theoretical physics) organizes the famous Colloquium Ehrenfestii, which is a natural sciences seminar meant for a general audience.

Other general mathematics colloquia are organized in
Amsterdam (UvA)   Delft   Groningen   Utrecht

No. 174 is a large lecture room meant for about 60 people. The room is equipped with both a blackboard and an overhead projector.
Usually, the audience consists of 20-30 people, among whom faculty and Ph-D. students from various branches of mathematics as well as guests from abroad. Therefore, speakers are expected to present their lectures in English, and to make their lectures accessible to non-specialists.
Speakers are welcome to meet any of the organizers before the start of the lecture. The offices of the organizers are on the third floor (Jan-Hendrik Evertse, room 228, Floske Spieksma, room 248; after entering the building take the elevator on the left and get off at the third floor (push 2). Then take the corridor to the right. Offices 228 and 248 are both on the right-hand side of this corridor; no. 228 is about half way and no. 248 at the end. The library of the institute is also on the third floor (after exiting the elevator take the corridor to the left).
