Everything tends toward disorder. Unless we choose otherwise.

Ideas from outside your field

Scientists, founders, artists and researchers share one stage. Each talk is something to carry back into your own work.

More than talks

Discovery Sessions and conversations run all day, so the ideas keep moving after the applause.

Scientists, engineers, founders, artists, researchers, students and the plainly curious, from across Cambridge and Boston.

The people in the room

The stage is one part of the day. The rest is the room: founders, researchers, artists and organizers who came to listen and stayed to talk. The conversations between sessions are often the ones that last.
