Thanks to a recent post on aperiodical by Dr. Peter Rowlett (advertising the 13th episode of the program) I tuned in and have found myself absorbed in both maths news and cool mathsy [sic] puzzles. Thank you Colin and Dave for bringing this podcast to iTunes and allowing some of us across the pond to enjoy some conversations between people who use the proper term of “maths” when discussing mathematics.
