The photo on their web site doesn’t do it any justice. Trever Nicholas‘s Luma is based on the concept of a […]

Alas, I was unable to travel and the panel was canceled. However, one of of the other panelists blogged about what he would have said. I’ll post a […]

For example, suppose three urns are filled with the following balls. Urn 1: […]
