A discussion of

"Undiluted Hocus-Pocus:
The Autobiography of Martin Gardner"

"Martin Gardner wrote the Mathematical Games column for Scientific American for twenty-five years and published more than seventy books on topics as diverse as magic, philosophy, religion, pseudoscience and Alice in Wonderland. His informal, recreational approach to mathematics delighted countless readers and inspired many to pursue careers in mathematics and the sciences. Gardner's illuminating autobiography is a disarmingly candid self-portrait of the man evolutionary theorist Stephen Jay Gould called our "single brightest beacon" for the defense of rationality and good science against mysticism and anti-intellectualism."

@ColinTheMathmo I won't be able to join this, but the books of #MartinGardner's "Mathematical Games" Scientific American columns helped prompt my interest in the subject back when I was at school - and I remember when going to a university admissions interview in #maths, there was one of his "Aha!" books put out for candidates to read while waiting in the corridor.
