July 24-28, 2008 (Excursion on Saturday July 26)
July 29 Mathematical Art Public Activity Day

Five days of Bridges Conference activities (July 24-28)
including an Escher Day on July 28,
are followed by a Family Math/Art Day (July 29).


The Bridges Conferences, running annually since 1998, brings together practicing mathematicians, scientists, artists, educators, musicians, writers, computer scientists, sculptors, dancers, weavers, model builders in a lively atmosphere of exchange and mutual encouragement. Important components of these conferences, in addition to formal presentations, are hands-on workshops, gallery displays of visual art, working sessions with artists who are crossing the mathematics-arts boundaries, and musical/theatrical events in the evening.


In addition to a set of extraordinary speakers and many intellectually stimulating sessions in the connections of mathematics, science, and the arts, the 2008 conference also offers the following events:

BTTB Workshops

Bridges for Teachers, Teachers for Bridges (BTTB) is a collection of special workshop sessions with a theme Fostering Understanding of Mathematical Visualization. BTTB is organized for K-12 teachers.

Musical Event

There will be a night of music performed by a combination of Bridges conference participants and professionals.

Visual Art Exhibit

The Conference will be complemented by an exhibit of mathematical art. There are opportunities for participants and contributors to show their work in the exhibition (see instructions below).

The Excursion

The excursion starts from the conference site and takes the people to several monumental and historical churches built during the middle Ages that also are the exhibit place of artwork of several modern artists from the Netherlands and other European countries. The churches are located in beautiful landscapes surrounding the city of Leeuwarden.  The excursion then will continue with a guided tour of the city of Leeuwarden including visits to the National Ceramics Museum Het Princessehof (Birth house of M.C. Escher), and Fries museum.  The tour ends with the visit of the Leeuwarden City Hall building and a reception in that building.  The tickets will be sold during the first day of the conference.


The Bridges Leeuwarden Conference will be held at the Christelijke Hogeschool in the Netherlands (CHN University), Leeuwarden.

Leeuwarden, as capital of the province of Friesland is seat of the provincial authorities.

Well-known buildings in the city centre include the Kanselarij (the former chancellery), the Waag (old trade centre of the city), the church of St. Bonifatius and the leaning tower Oldehove. One of the eye catchers in the city centre is the ‘Achmea building’ (it belongs to Achmea insurance) which is near the train station. The Achmea building is the tallest building in the city.

Leeuwarden is also the site of the country's largest cattle market, and on Ascension Day the largest flower market in the Netherlands is held here.

For information about how to get to the school, please see the “Location and Travel Guide” on the Bridges website.


Participants have a wide range of selections from four star hotels (with discount) to bed and breakfast facilities, and apartments.  The list of all the accommodations and their prices will be posted during December 2007.

Meals: The campus facility has a dining hall that serves breakfast and lunch every day.  For dinner there is an extensive collection of restaurants offering international cuisine of many types, ranging from simple to luxurious, within walking distance from the university.


The conference will feature presentations of regular, plenary, and short papers, as well as several workshops. The program for the conference is composed from a combination of submitted and invited presentations.

Papers submissions are due by February 1, 2008 for the reviewing process.

Because some people have had difficulties with the new electronic submission system,
the 2008 submission deadline is extended to February 8.

Detailed submission information is available here.

Regular and plenary presentations require a regular paper  with a maximum length of eight pages; short presentations require a two page short paper; and workshops can be accompanied by either a regular or a short paper.

All papers are to be submitted properly formatted as they would appear in the conference proceedings (see the formatting instructions and template on the Bridges website). Papers that ignore the formatting guidelines or the length limits will not be entered into the reviewing process.

In order to have as diverse a representation of authors as possible and to keep the proceedings to a reasonable size, conference participants can be the main author and presenter on only one paper. The main author on each submitted paper should be identified with an asterisk: “*”. This rule includes all contributions: short and regular papers as well as workshop papers.

The regular presentations will be given a 25 minute time slot; short presentations will be given a 15-minute time slot.


The Conference plans to distribute the refereed Proceedings at the conference. Thus, there is a tight and firm schedule:

Deadline for paper submissions for review: February 1, 2008

Submission instructions are given here.

Notification of acceptance of paper: March 25, 2008.

Deadline for submission of final electronic manuscript: April 25, 2008.

All papers must follow the format specified on the Bridges website.  You must also complete your registration by this date. Please note that one non-refundable full registration is required for one author of each paper.

Please note that if you plan to use the on-campus accommodations, you also need to register and pay in full for your accommodations by this deadline.  Of course, you may still seek accommodations outside of campus after this deadline.

The 1998-2006 Bridges Proceedings are available through the online store


The key theme is: “Bridges for Teachers – Teachers for Bridges”

There will be several teacher workshops for K-12 teachers and educators at the 2008 Bridges Conference. If you are interested in making a presentation in one of these workshops you need to submit either a short (two page) or long (eight page) paper; The deadlines for submissions of preliminary and final versions are the same as for the contributed papers. However, the time frame for each accepted workshop will be between 45 and 75 minutes, depending on the nature of the presentation and the time slots that are available. If the paper itself does not make it clear what exactly the activities are that you plan to do in your workshop, please add additional material to explain; this additional material is not intended for publication. Papers intended for the teacher workshops should be marked by the words "BTTB" on the top right corner of the first page of the article. The submission process is the same as for all other papers.


At the conference, there will be an exhibition room for 2D and 3D mathematical art, ranging from computer graphics to quilts to geometrical sculptures. This art exhibit will be curated by Robert Fathauer. All submitted artwork will undergo a refereeing process. There is a limit of five submissions per artist. Images of accepted artworks will also be published on the conference CD.

The primary intent of the art exhibit is to foster active interaction between exhibiting artists and conference participants. Thus we expect all exhibitors to attend the conference and require them to register once they obtain the notification that their work has been accepted. Work of non-registered participants will not be exhibited and will not appear on the conference CD.  Submissions and questions related to the art exhibit should be addressed by e-mail to:

Dr. Robert Fathauer, Tessellations Company,

If you would like to submit your work, please follow the instructions below. Nonconforming submissions will not be entered into the review process.

Please note that all the artworks should be hand delivered to the exhibit room on Monday July 23, 2008, preferably in the time frame 2 p.m. to 7 p.m.  The exhibit participants are also responsible for picking up their works at the end of the conference.   The artworks will not be insured while on display, so the artist assumes all risk for damage or theft.

The exhibit space will only accommodate a limited number of works, which may necessitate rejecting some good quality pieces.  Review criteria include:

• Math content (This is a mathematically sophisticated audience.)
• Esthetic appeal (This is admittedly highly subjective.)
• Medium (A variety of media will make for a more dynamic exhibit.)
• Craftsmanship (The level of skill and effort that goes into making an effective presentation of the idea.)

Due to space constraints, flat works will be limited in size to 24" x 36" (including frame), and 3-D works will be limited to 24" x 24" x 24". 

Please note that the works should be presented in a manner that would be appropriate for a mainstream art gallery.  This is to be contrasted to a poster session or technical illustration look, which most mathematicians are more accustomed to.

For examples of the sort of works that are appropriate, recent art exhibits from the Bridges Conference and Joint Mathematics Meetings are available for viewing online at

Images of any submitted artwork  and accompanying descriptive data and technical description (see below) should be submitted between February 15 and March 15, 2007, to:  Robert Fathauer ( Notification of acceptance will be made via e-mail by April 15.

For each piece of artwork (limited to 5 per artist) please submit the following:

An Image of the Work:

Images should be e-mailed as JPEG files with a dimension of between 500 and 600 pixels in the larger direction.  Color images should be in RGB format. Black and white images should be in grayscale format, not RGB, in order to minimize file size.  The file names for the images must conform to the following format – “Lastname1.JPG”. E.g., if John Doe submitted 2 works, the image for his second work would be called Doe2.JPG.
