<p>This week would have been the 100th birthday of Martin Gardner, who is deservedly credited with turning on several generations of people worldwide to the pleasures of maths! To mark the occasion here are some favourite puzzles that, apart from being fun, also lead to some serious maths.</p>

<p>American man of letters and numbers <a href="http://www.martin-gardner.org">Martin Gardner</a> was born 100 years ago, on 21 October 1914. Of the hundred or so books he left us, more than half are about mathematics and physics in some form. For over fifty years he championed puzzles and recreational mathematics, most famously in the <em>Scientific American</em> column he wrote regularly from 1957 to 1981. He's deservedly credited with turning on several generations of people worldwide to the pleasures of maths and creative problem solving in general.</p><p><a href="https://plus.maths.org/content/five-martin-gardner-eye-openers-involving-squares-and-cubes" target="_blank">read more</a></p>https://plus.maths.org/content/five-martin-gardner-eye-openers-involving-squares-and-cubes#commentsgeometrypuzzlerecreational gameMon, 20 Oct 2014 08:50:22 +0000mf3446209 at https://plus.maths.org/contentWhat mathematicians get up to
