Delivery of first year diplomas on Friday September 10
One year ago, the universities of Delft and Leiden started
a common Mathematics curriculum. On Friday September 10,
from 4:15-5:00 pm in room 174 of the Snellius there will be a meeting
at which the students from Delft and Leiden who have passed
the first year exam receive their diplomas. Before the actual delivery
of the diplomas there will be four short lectures in which the speakers
discuss their experiences with/ideas about the first year of the curriculum.
The speakers are Reinier Bröker (teacher of exercise classes in algebra,
Leiden), Joost de Groot (first year mentor, Delft), Robbert Fokkink
(chairman of the education committee, Delft), Frans Saris (dean of the
faculty of sciences, Leiden).
After the meeting from 5:00-5:30 pm there will be a "borrel" for the students
and their parents.
Mathematical Institute Barbecue 2004 on Friday September 10
After the "borrel" mentioned above, from 5:45-8:30 pm there will be a
barbecue for the employees of the Mathematical Institute, their partners
and children, and our guests from Delft. The barbecue is on the inner
court of the Snellius, near to the bar on the ground floor.
Please contact Jeanine Daems
