Michael Wendl (and here) dissects some variants of the magic separation, a self-working card trick…
Martin Gardner—one of history’s most prolific maths popularisers [see here]—frequently examined the connection between mathematics and magic, commonly looking at tricks using standard playing cards. He often discussed ‘self-working’ illusions that function in a strictly mechanical way, without any reliance on sleight of hand, card counting, pre-arrangement, marking, or key-carding of the deck. One of the more interesting specimens in this genre is a matching trick called the magic separation.
This trick can be performed with 20 cards. Ten of the cards are turned face-up, with the deck then shuffled thoroughly by both the performer and, importantly, the spectator. The performer then deals 10 cards to the spectator and keeps the remainder for herself. This can be done blindfolded to preclude tracking or counting. Not knowing the distribution of cards, our performer announces she will rearrange her own cards ‘magically’ so that the number of face-ups she holds matches the number of face-ups the spectator has. When cards are displayed, the counts do indeed match. She easily repeats the feat for hecklers who claim luck…

As we conjure, we might spare a thought for Persian polymath Omar Khayyam; the mathematician, philosopher, astronomer, epigrammatist, and poet died on this date in 1131. While he’s probably best known to English-speakers as a poet, via Edward FitzGerald’s famous translation of the quatrains that comprise the Rubaiyat of Omar Khayyam, Omar was one of the major mathematicians and astronomers of the medieval period. He is the author of one of the most important works on algebra written before modern times, the Treatise on Demonstration of Problems of Algebra (which includes a geometric method for solving cubic equations by intersecting a hyperbola with a circle). His astronomical observations contributed to the reform of the Persian calendar. And he made important contributions to mechanics, geography, mineralogy, music, climatology, and Islamic theology.

Day after tomorrow– this this Wednesday, the 27th– Sotheby’s will be auctioning the late, great Ricky Jay’s remarkable collection of magic publications and artifacts…
… You have the rare opportunity to get your hands on a complete guide to the base practices of highwaymen, sharpers, swindlers, money-droppers, duffers, setters, mock-auctions, quacks, bawds, jilts, etc. in eighteenth-century London.
That text is part of The Ricky Jay Collection, perhaps the world’s greatest assemblage of books on magic, deception, and trickery. As detailed in this enjoyable New York Times report, the Sotheby’s sale is a cornucopia of oddities from the late conjurer.
What’s really for sale — beyond the Houdini posters, guides to card tricks, and beautiful landscapes painted by armless entertainers — is the source material for Ricky Jay’s storytelling.
Jay (1946-2018) was, by all accounts, one of the world’s greatest practitioners of legerdemain, a word that literally translates as light of hand [see here for its amusing etymology]. In other words, he did card tricks. But not just any card tricks: His 1977 book Cards As Weapons (available for free here!) begins with a letter to the Secretary of Defense explaining just how valuable his skills might be:
“Drawing on techniques developed hundreds of years ago by ‘ninja’ assassins, I have developed my own system of self-defence based solely on a pack of cards,” he wrote. “I believe I have discovered a viable method of reducing the defence budget while keeping a few steps ahead of the Russkies.”
And Jay could indeed pierce the skin of a watermelon with a playing card from across a room. But when you came right down to what he did with his 52 assistants, the man was famous for moving pieces of waxed paper around on a table. The gulf between collating stationery and “the theatrical representation of the defiance of natural law” was filled by his deep knowledge and ready wit.
One of his signature tricks was The Four Queens, in which the waxed rectangles with the Qs in their corners are blended into the pack and need to be reunited. Or as Jay framed it, “I have taken advantage of these tenderly nurtured and unsophisticated young ladies by placing them in positions extremely galling to their aristocratic sensibilities.”
You can really see the storytelling taking shape here in his Sword of Vengeance trick. What do shogun assassins have to do with cards? That’s exactly what you forget to ask until it’s too late:
Jay’s ability to unspool a story was clearly infectious, as his profilers couldn’t resist taking flights of erudition.
“He’s like someone carving scrimshaw while surrounded by Macy’s Thanksgiving Day dirigibles,” wrote Tom Carson in Grantland.
“His patter was voluble, embroidered with orotund, baroque locutions; he would describe the watermelon rind, for instance, as the ‘thick pachydermatous outer melon layer’,” wrote Mark Singer in The New Yorker.
To include him in the pantheon of Great Wits is to recognize why he amassed The Ricky Jay Collection and what he learned from it. The shaggy dog story, as previously detailed in GWQ #101, is a psychological non-sequitur: You follow it at great length to eventually learn it goes nowhere. But in Ricky Jay’s dexterous hands, the story was an ideal way to distract you from his dexterous hands. His words were how he could really transport the audience into a world of wonders. It’s as if he harnessed the shaggy dogs and mushed them through the Iditarod…

As we riffle and cut, we might send accomplished birthday greetings to Marion Eileen Ross; she was born on this date in 1928. An actress with a long history in film (e.g., The Glenn Miller Story, Sabrina, Lust for Life, Teacher’s Pet, Some Came Running, and Operation Petticoat), she is best remembered for her role as Marion Cunningham on the sitcom Happy Days, on which she starred from 1974 to 1984 and for which she received two Primetime Emmy Award nominations. (That said, your correspondent will always remember her for her remarkable performances as Grandma SquarePants in SpongeBob SquarePants.)
