Friday News Mar 24: Celebrating the Ein Stein, Gather Social, New Video

• Celebrating the Ein Stein

  This weekend on Sunday at 12 noon ET (Atlanta time*), we will host a Zoom session (at a new URL, see below) to celebrate this week’s extraordinary announcement by David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss of the discovery of an aperiodic monotile: a single tile which (along with its mirror image) tiles the infinite 2D plane aperiodically.

  The session will be recorded, and we may later post edited highlights on the G4G YouTube channel.

  Participants will need the meeting ID and passcode if they join directly from Zoom, without using the link. People will be able to see each other if they have webcams. Share screen will also be available.
