June 22-26, 2004 Massachusetts Institute of Technology

Program

The conference talks will be held in building 54 (the Green building, the tallest building on campus) every day except Friday. There are front and back entrances to 54-100 from different staircases. On most days, we will also have access to a lounge on the 9th floor with a reasonable view and lots of seating space. There are also benches outside the building.

On Friday, the conference will be held in 34-101. The main entrance to 34-101 is off of Vassar Street. Please do not arrive late for talks in 34-101 as the entrance is under the overhead projector screen. (Well, please don't be late regardless, but especially on Friday.)
