Can you change “100″ to “CAT” by moving just two of these toothpicks?

The above puzzle is probably familiar to many lovers of logic games, but new to the multitude who have not yet made the connection between mathematical problems, visual conundrums, and, of all things, fun.
One man who spent a lifetime reaching out to both the initiates and the multitude was Martin Gardner, philosopher, mathematician, magician, and for 25 years the author of the “Mathematical Games” column in the Scientific American. He was also a founding member of the LCSNA and the creator of the irreplaceable Annotated Alice books.
 Martin Gardner
When Martin died last year the foundation Gathering for Gardner vowed to “celebrate Martin’s life and work, and continue his pursuit of a playful and fun approach to Mathematics, Science, Art, Magic, Puzzles and all of his other interests and writings.” One of these celebrations is fast upon us – the second annual Celebration of Mind events to be held worldwide on or around what would have been Martin’s 97th birthday – October 21, 2011.
Last year, people gathered to share magic tricks, puzzles, recreational mathematics problems and stories about Martin at 66 locations from Tokyo to Tehran to Buenos Aires to Boulder, Colorado. This year, 30 hosts have signed up already and the organizers expect many more – if you can’t make the gathering at the McMurdo Station in Antarctica, how about attending one of the 15 already listed in North America? Events held by LCSNA members will undoubtedly have an Alice flavor – if you are hosting one, be sure to get in touch and we will advertise it on the blog.
I wonder how many events this year will feature readings from A Bouquet for the Gardener, the beautiful collection of tributes and reminiscences published by the LCSNA in July? (Available at Amazon.com.)
For a map of planned events, and for guidelines for hosting your own event, go to the Gathering for Gardner website. There you can also find photos and descriptions of previous events along with downloadable visual treats and puzzles to whet your appetite. You can also follow event updates on Twitter account @G4G_CoM.
And finally, if you haven’t figured out the toothpick teaser above, I’m not going to tell you. What are Sunday afternoons for?
Callooh! Callay!! We are delighted to announce that the LCSNA has just published a frabjous new book paying tribute to the late, great Martin Gardner–columnist, philosopher, polymath, magician, religious thinker, and author of more than 70 books, including the groundbreaking Annotated Alice.
The LCSNA’s beautiful 234-page hardcover is a delightful portmanteau accomplishment, combining entertaining and heartfelt reminiscences from those who knew Gardner with a traditional festschrift (academic essays written in his honor). The book is introduced by Gardner’s son Jim, and includes contributions from such noted authors as Douglas Hofstadter, Morton N. Cohen, Scott Kim, David Singmaster, Michael Patrick Hearn, Raymond Smullyan, and Robin Wilson, to name but a few. Our book also contains Gardner’s own final, post-”Definitive Edition” addenda to his towering Annotated Alice classic, as well as an authoritative bibliography of Gardner’s Carroll-related writings.
A Bouquet for the Gardener is a must-read for anyone who loves Lewis Carroll, puzzles, logic, math, and great thinking on a wide range of topics. Current members of the LCSNA will be mailed one free copy as a bonus of membership. We are thrilled to be able to make this important book available to the public as well via Amazon (US link; UK link). Members can also buy additional copies on Amazon.
Our thanks to all who contributed to this effort, both on the pages and behind the scenes. It is impossible to overstate the debt we all owe to Martin Gardner. We invite you to join us in saying thank you and in celebrating his remarkable life by reading A Bouquet for the Gardener.
So far, sixty-six parties have been coordinated around the planet to commemorate the giant Carrollian, Martin Gardner (October 21, 1914 – May 22, 2010) on what would have been his 96th birthday, Thursday. The website g4g-com.org (possibly named by Dr. Evil) invites you to join them “in celebrating the life of Martin Gardner by attending or hosting a G4G Celebration of Mind Party.” There are maps to help find you one in your area, and a Twitter account @G4G_Com has a cacophony of tweets about the ever-increasing number of events.
With great sadness we note the passing of Martin Gardner this past Saturday, May 22, 2010, in Norman, Oklahoma at the age of 95. Martin Gardner was not only a founding member of the Lewis Carroll Society of North America but also, it is surely safe to say, the founder of serious Carroll studies through the publication of his book The Annotated Alice. That work, which went through three editions (The Annotated Alice, 1960; More Annotated Alice, 1990, and The Annotated Alice: The Definitive Edition, 2000) introduced countless numbers of people to Lewis Carroll’s Alice, thereby bringing Carroll’s works to the popular mind as never before. His Annotated Alice also set the standard, one seldom equalled, for a numerous succession of annotated works by other authors. In 1962 he published his Annotated Hunting of the Snark, reprinted in 2006 in an expanded, definitive edition with a brilliant introduction and appreciation by Adam Gopnik.
Like Lewis Carroll, Martin Gardner had a deep appreciation for serious and recreational mathematics [he wrote the famous “Mathematical Games” column in Scientific American for 25 years with more than a few touching on Carroll], a love of language and paradox, and a profound interest in religion. Like Houdini, he was keen on magic tricks and equally intolerant of paranormalists and other charlatans.
Martin was always willing to help those who corresponded with him and, although some of us never had the privilege of meeting him, we all knew him and counted him both a learned guide and an always generous friend.
