Martin Gardner, born on October 21, 1914, was an American popular mathematics and science writer specializing in recreational mathematics, but with interests encompassing micro-magic, literature (especially the writings of Lewis Carroll and G.K. Chesterton), philosophy, scientific skepticism, religion – and chess. He published more than 100 books and almost all of his columns have been collected in book form. Martin Gardner died in 2010 at age 95, razor sharp until the end. Today he would have been 100 years old.
The caption to the above pictures by Colm Mulcahy, Spelman College, reads: "Martin standing by every word he ever wrote: the six shelves consist entirely of his own publications, dating back to 1930."
I corresponded with Martin Gardner in my teen years, and I can safely say that he played a greater role in my intellectual development than almost anyone else (and I am in good company here). I corresponded with him during my school and college days and followed his columns and writings for decades. Our readers must forgive this rather lengthy celebration of his 100th anniversary – it has personal reasons.
In 1979 I visited Martin Gardner in his home in Hastings-on-Hudson. He and many others (including myself) had recently founded the skeptical Committee for Investigation of Claims of the Paranormal, which mutated into the Committee of Skeptical Inquiry and became the publisher of the Skeptical Inquirer. It was the first time I met him in person.
Gardner's uncompromising attitude toward pseudoscience made him one of the foremost anti-pseudoscience polemicists of the 20th century. His book Fads and Fallacies in the Name of Science (1952, revised 1957) is a classic and seminal work of the skeptical movement. It explored myriad dubious outlooks and projects including Fletcherism, creationism, food faddism, Charles Fort, Rudolf Steiner, Scientology, Dianetics, UFOs, dowsing, extra-sensory perception, the Bates method, and psychokinesis. This book and his subsequent efforts earned him a wealth of detractors and antagonists in the fields of "fringe science" and New Age philosophy, with many of whom he kept up running dialogs (both public and private) for decades.
Martin Gardner's column on mathematical puzzles and diversions in Scientific American were my first contact with the work of this extraordinary man. I was still an early teen in school, but I sent letters (handwritten, on paper, with envelopes and stamps) with comments and solutions. He replied to every single one of them – in my boundless stupidity I did not keep his type-written letters, which are lost forever. I have added some comments to the following puzzles from memory.
If you want to get an impression of the vintage Martin Gardner get hold, if you can, of a copy of his book "Hexaflexagons and other mathematical diversions". It is also available as a PDF file here. You can spend a week or two, as I did in my college days, building hexahexaflexagons (or read the article on them here in Scientific American). Or you can try some of the puzzles that have become legendary. Here a sample:
The props for this problem are a chessboard and 32 dominoes. Each domino is of such size that it exactly covers two adjacent squares on the board. The 32 dominoes therefore can cover all 64 of the chessboard squares. But now suppose we cut off two squares at diagonally opposite corners of the board and discard one of the dominoes. Is it possible to place the 31 dominoes on the board so that all the remaining 62 squares are covered? If so, show how it can be done. If not, prove it impossible.
I participated vigorously the the discussion given in the book. Some ChessBase readers will recall that I used this problem at the end of one of our Christmas Puzzle weeks.
My most memorable exchange with Martin Gardner was over this problem. At the time I sent him the following solution: "I do not (yet) have the mathematical skills to solve this problem. But assuming that the text does not contain a misprint it would appear that it is not necessary to know the diameter of the sphere or the drill bit. Just the length of the cylindrical hole through the middle is enough, the remaining volume will be constant. If that is the case then I can drill a hole of zero diameter through a sphere with a diameter of six inches. So the remaining volume will be 4/3 Pi r³ = 113.09733 cubic inches (I can do volume of a sphere)." Martin wrote back commending my ingenuity, and many years later, when I finally met him, the remembered this exchange and even the fairly silly pseudonym I had used at the time.
The answers to the puzzles are given in the above book – print or PDF. A more recent puzzle involved a desk block perpetual calendar (like this one). The day is indicated simply by arranging two cubes so that their front faces gave the date. The face of each cube has a single digit, 0 through 9, and one can arrange the cubes so that their front faces indicated any date from 01, 02, 03 … to 31. On the left cube of the calendar shown on the right you can see two faces whose digits are 1 and 2. On the right cube you can see three faces, whose digits are 1, 3 and 4. What are the four digits that cannot not be seen on the left cube and the three that cannot be seen on the right cube?
In case you get hooked, there are many other Gardner books with mathematical and logical puzzles. Here I would like to add one (of the many) he gave me when I visited him in in Hastings-on-Hudson in 1979: There are three on/off switches on the ground floor of a house. One is connected to a light bulb on the second floor, the other two are unconnected. The switches are all in the off position. You can switch any position and then climb the stairs to the second floor and examine the bulb. Can you tell which switch is connected in a single try?
The chess enthusiastIn May 2010, shortly after the death of Martin Gardner at the age of 95, Tom Braunlich wrote a eulogy for Chess Life. A link to the article is given below – here are some excerpts:
Martin Gardner was an enduring fan of chess and once played two tournament games with Sammy Reshevsky! Gardner was born in Tulsa, Oklahoma, in 1914 and played chess there in high school until he was graduated in 1931. Later at the University of Chicago he continued as an enthusiastic amateur player. There he met the famous grandmaster. Gardner told me the story.
In those days [the early 1930s] Reshevsky was having difficulty making a living as a professional chess player during the Great Depression, and he had decided to give up the game and take up accounting. He enrolled at the University of Chicago to study for a degree. We had a small chess club going at the university then where I would play, and of course we became aware that Reshevsky was at the school. But we were disappointed that he never came by the chess club to play. Of course, he had no reason to come, as we were all far below his level, and he was trying to give up the game anyway. But those of us in the club hatched a plan to get him. We took up a collection and raised $50 for a guaranteed first prize for a tournament. We put up flyers around the school advertising a double round robin event, making sure to put plenty of flyers around the accounting department. Sure enough, Reshevsky showed up to register for the tournament! $50 was a lot of money in those days and, as we expected, the temptation was too much for him.
Since it was a double-round robin, I got to play him twice. In the first game, I made an error in the opening leaving myself open to a direct attack. But I was surprised he didn’t take that opportunity, continuing instead to just make strong building moves and playing for position, eventually overwhelming me.
Gardner never really lost his love for chess, often using unusual chess puzzles in his columns, but only if they related to mathematical principles he was discussing. An example of this would be the “Eight Queens” puzzle (i.e., how do you place eight queens on a chessboard so that no two queens attack each other?), which could then be generalized to n number of queens on an n by n board and underlying principles revealed. – Read the full article in Chess Life Online here.
The Eight Queens problem has 92 destinct solutions, twelve if you discount those that differ only by symmetry operations (rotations and reflections) of the board. Gardner took it further: place three white queens and five black queens on a 5 x 5 chessboard so that no queen of one colour is attacking one of the other colour. There is only one solution to this problem, excluding reflections and rotations.
The 5 x 5 board comes from a minichess version invented by Gardner in 1969. He proposed a chess variant played on a 5×5 board in which all chess moves, including pawn double-move, en-passant capture as well as castling can be made. The game was largely played in Italy (including by correspondence) and opening theory was developed. The statistics of the finished games is the following: White won 40% of games, Black won 28%, 32% were draws (Gardner's minichess was solved in 2013, and the game-theoretic value turned out to be a draw). In 1980 HP shipped HP-41C programmable calculator, which could play this game at a fairly decent level.
In 1989, Gardner proposed another setup, which he called Baby chess. In difference from Gardner minichess, kings are placed into opposite corners here. – For more information on minichess see this Wikipedia article.
Chess and cheatingIn January 1948 (!) Martin Gardner wrote a short story for the magazine Esquire, Nora Says 'Check', which was subsequently reprinted in a volume of Gardner’s early fiction, The No-Sided Professor. In this story Sierpinsky, the world champion, alleviates his chess boredom by guiding a not very bright waitress named Nora to chess fame with the help of a confederate. During each of Nora’s tournaments the confederate watches from the audience, communicating with a hidden Sierpinsky via a toe-interfaced shoe radio and with the waitress through a language of gestures. The story also anticipates the so-called hippopotamus chess opening – further Sierpinsky boredom alleviation – by nine years. A third Gardnerian anticipation of future chess history flows out of the success of Sierpinski’s hijinks. A world championship chess match transcends all previous bounds of public attention, inflaming the masses from the front page of Pravda to the cover of Time. Of course, this particular world championship match is especially amusing: puppet master and puppet on stage together, still mediated by cigar chomping confederate. Even more amusing is the Frankensteinian catastrophe that befalls Sierpinski at the very climax of his carefully constructed finale. A fourth manifestation of chess prescience – this one almost spooky – appears in the last sentences of the story in the form of an eight-year-old boy from the Bronx. Summary by Danny Purvis – read the entire story here.
Martin Gardner was best known for sustaining and nurturing interest in recreational mathematics for a large part of the 20th century, particularly through his "Mathematical Games" column (from 1956 to 1981) in Scientific American. The October issue has a six-page article on him.
Like a good magic trick, a clever puzzle can inspire awe, reveal mathematical truths and prompt important questions. At least that is what Martin Gardner thought. His name is synonymous with the legendary Mathematical Games column he wrote for a quarter of a century in Scientific American. Thanks to his own mathemagical skills, Gardner presented noteworthy mathematics every month with all the wonder of legerdemain and, in so doing, captivated a huge readership worldwide. Many people—obscure, famous and in between—have cited Mathematical Games as informing their decisions to pursue mathematics or a related field professionally. – From Scientific American October 2014, pp 78-83.
The Mathematical Association of America has just shown 40 minutes of interview footage recorded with the 79-year-old Gardner in 1994 at his Hendersonville, North Carolina, home. Until recently it was stored only on a pair of video cassettes formatted for broadcast television. They were found in a cupboard at MAA headquarters and transferred to DVD. A 14-minute segment of the interview was uploaded to Youtube on October 15, 2014.
