Dear FOMers, Sad news: Petr Vopenka passed away on March 20, 2015. Some of you might be interested to watch a (free) 22-min Cech documentary on Vopenka (with English subtitles) made in 2006; there is a surprise half-way through, about the origins of Vopenka cardinals. http://docalliancefilms.com/film/891 Best regards, Ali Enayat
