Mathematical Play in honour of Richard Guy: A day of recreational math for high school students

Richard Guy was an enthusiastic participant in recreational mathematics.  We invited high school students to propagate his love of doing math for fun by joining us to solve mathematical puzzles, problems and challenges.  Problems from a special issue of Crux Mathematicorum dedicated to Richard Guy were distributed on Saturday morning by email to registered participants.  Mathematicians were available via Zoom in drop in sessions to discuss the problems with students, and to offer additional hourly challenges.  Participants were invited to post their solutions on a discussion board, and notable contributions by students were recognized during the closing ceremonies session. Organized by Dr. Bill Sands and Dr. Lauren DeDieu.

Date: Saturday, October 3, 2020

“Peace is a disarming concept”: a celebration of the life of Richard Guy

Richard and Louise’s family and their many friends raised a cup of hot chocolate together and celebrated the impact their lives have had beyond the world of mathematics. Friends and family spent time celebrating Richard’s passion for mathematics and how he shared this passion with others.   It was a time for family, friends, and colleagues to share their memories of Richard and reflect on the impact he has made to the community and in their lives.
