Benedict de Spinoza (1632 - 1677) was a Dutch religious philosopher of Portuguese Jewish descent, who expressed, for his time, enlightened views about the physical nature of the world he lived in. In his name, Gerard 't Hooft received a grant to be used for research projects. One of these will be the

Spinoza Meeting on the Quantum Black Hole

The Meeting is intended to give the participants optimum opportunity to exchange their ideas about the internal quantum states in a black hole. Their research should not be held up by the need to write contributions to proceedings, and we hope that the most provocative ideas are launched, shot down, and then replaced by others. To underline the informal nature of this Meeting, the lecturers will be strongly encouraged to use the blackboard rather than viewgraphs. Special discussion sessions are planned.

Some details concerning the programme may be changed later. Click this page after a few weeks to check for further information.


The selection procedure, originally planned to be very rigid, has been eased a bit because a larger lecture hall could be reserved.


Registration fee: Hfl 200. This includes lunch, coffee/tea and Conference Dinner, all of which are also subsidised by the Spinoza grant.

Applications can be sent to the secretariat listed below, as soon as possible. It is advisable to include a CV and a short publication list.
After selection, a registration form will be mailed to the applicant. In view of limited hotel space, it is urgently advised to register as soon as possible.


Date: June 29 (Arrival, welcome, registration) - July 4 (departure), 1998
Location: The Minnaert Building, Leuvenlaan 4, De Uithof, Utrecht, The Netherlands.
The lectures will be held in het Gebouw voor Aardwetenschappen, Budapestlaan 4, De Uithof, which is connected to the Minnaert building by an overpass.


On Saturday, July 4, public lecture will be given by Prof. Stephen Hawking. This lecture is not intended for the participants of the Spinoza Meeting, but for students and the general public of interested non-experts. For further information and reservations send an e-mail to hzu@fbu.ruu.nl

Abstracts (so-far)

We ask the other speakers to submit the titles of their lectures, so that these can be displayed on this page. Abstracts are also welcome, but because of the informal nature of our meeting, we leave this as optional.


Information about participating at this meeting, and hotel 
reservations, can be obtained from:

(The postal address given previously may also be used, but we discovered that mail directed to that address takes more time to arrive)


MAPS of the town of Utrecht and of the university area De Uithof can be clicked here.
Note that this map does not yet show the Minnaert building, which is located just south of the physics building ("Natuur- en Sterrenkunde"), connected to the latter by an overpass. It is also connected to the building "Aardwetenschappen", where the lecture hall is located.
