John Durant, Director of the MIT Museum, introduces David Altshuler.

At 1:14, Altshuler begins.

At 36:24, Durant invites groups to assemble and formulate questions for discussion. (Note: The 15 minute small group discussion has been edited out, so the video jumps to the questions offered by the group.)

At 37:30, Altshuler reads the questions written by the groups, and then responds to questions posed by audience members.

At 1:03:51, Durant thanks Altshuler and the audience-participants.
