Bridges: Mathematical Connections in Art, Music, and Science

School of Architecture, The University of the Basque Country

San Sebastian (Donostia), Spain

July 24-27, 2007 

The conference consists of a 4-day combination of Bridges Conference activities (July 24, 26, and 27) and an excursion day to Bilbao (July 25).


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 2007 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. The special feature for this year’s music performance will be the introduction of maestro A. Borhani.  He will play several Persian classical instruments such as the Tar, Setar, Santur, Daf, and Tonbak. He will also talk about their relationships with other disciplines.

Visual Art Exhibit

The Bridges Donostia 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 Bilbao Excursion

Bilbao, founded 700 years ago, is a classic European city in every respect. Uncluttered and easily explored on foot, its wide open boulevards feature interesting public buildings, museums, parks and the titanium clad Guggenheim Museum (a highlight of the trip). A delightful riverside stroll will take you to the Old Quarter where Renaissance, Baroque, Neoclassic and Modernist buildings house innovative shops and traditional Basque restaurants and tapas bars. Bilbao is also a friendly, open city where visitors are welcomed and made to feel at home.  Please note that this excursion includes a trip to the Chillida Sculpture Garden. The tickets for this excursion will be sold during the first day of the conference.


The Bridges Donostia Conference will be held at the School of Architecture at the University of the Basque Country in San Sebastián, Spain.

San Sebastián (Donostia in Basque) is the capital city of the province of Guipuzcoa, in the Spanish autonomous community of the Basque Country. The city is located in the northeast of Spain, on the Bay of Biscay, close to the French border. San Sebastián's picturesque coastline makes it a popular beach resort.

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


Participants have a choice of staying in the campus facilities (comparable to a three star hotel and within walking distance of the conference site) or staying in a nearby hotels (a list of hotels is provided on the “Accommodations” section of the Bridges website).

The on-campus accommodations are high-quality facilities for singles or couples. They include complete breakfasts for every day of stay. The "Conference Dorm Basic Package" covers the nights of July 23--27.  The package is available only for a block of all five nights; it costs 280 Euros for singles and 450 Euros for couples.  The registration deadline for on-campus accommodations is April 23, 2007.

Package rates are for arrival on July 23 and departure on July 28. People may extend their stay by two nights before and/or after the conference.

The availability of campus accommodation is limited. For information about on-campus accommodation and registration, and for making reservations, please go to the “Accommodations” page on the Bridges website.  The page also contains a list of hotels within walking distance of the conference.

Meals: The campus facility has a beautiful dining hall that serves breakfast every day. For lunch and 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, 2007 for the reviewing process.

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, 2007

Please send a copy of your submission as a Microsoft Word or PDF file to

If electronic submission is impossible, please contact Reza Sarhangi to make alternate arrangements.

Notification of acceptance of paper: March 25, 2007.

Deadline for submission of final electronic manuscript: Monday April 25, 2007.

All papers must follow the format specified on the Bridges website.  You must also complete you 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 2007 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, 2007, 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.
