I have recently become very interested in this principle, it is strange how people have more trouble understanding this than convergence. Remarkable. Anyway, one of my new favs is 'The angel may shuffle but the devil still deals'. Anybody else have favourite GP tricks?

In no particular order:
"Aunt Mary's Terrible Secret" by David Williamson (available in a book of the same name) "Best Bet Yet" by Terry LaGerould (From "A Magical Baker's Dozen", available via Lew Brooks) "Please Don't Match" by Terry LaGerould (unpublished) - In this effect, the spectator shuffles the deck, takes out 7 cards, and shuffles them. These cards are torn in half, and then these 14 halves are shuffled together. This half-card stack is placed into the performer's pocket (examined previously), and he pulls cards from the pocket one by one, betting that he'll never pull out the remaining half of any card that was previously pulled. The performer always wins the bet. |

While I know several effects based on the Gilbreath Principle, and I know it is "a thing of terrifying beauty," I don't precisely know the exact principle itself. Where can I find a write up defining and detailing the Gilbreath Principle?

With Playing Cards Martin Gardner If you want some homework! faculty1.coloradocollege.edu I will look for better explanations...although using coloured balls in tubes is a good way to explain it visually (ask me for details if you like). Are you looking for academic formal analysis or a (mathematically speaking) laymans explanation? Our own Jim Morton has offered to e-mail anyone a PDF on the subject in a previous thread: http://www.themagiccafe.com/forums/viewt......2&38 Which also has some great tricks listed already for this topic, still even though I found that I wanted to start a new thread and hear what people think (maybe someone has changed their mind...or there are new people unaware of the beauty).

I am hoping that Phil Goldstein will in fact publish his long-awaited book on Gilbreath before I am too old to shuffle a deck of cards. If it is anything like as clear an explanation of Gilbreath as "Redivider" was of Rusduck, all of us like rgranville and me who are still not sure we understand Gilbreath will rejoice. "Redivider" was wonderful -- the right mix of theory and effects for a non-mathematical layperson like me.

But I do have a mathematical background. I have asked Jim Morton for his writeup. I'm still looking for a precise definition of the principle.

I'm still looking for a precise definition of the principle. Well, the scientific literature about this principle quote the Linking Ring article by Gilbreath ! I found some references about the Gilbreath principle not for any real use, but as a test for inductive theorem prover programs : Gilbreath's principle is at the same time easy to formalize, and non-trivial when you want to convince someone that your prover has "found something" that was "neither written in the rules nor in the prover", I guess. You can find such a reference in : www.cs.utexas.edu which starts with : Quote:

I think I'm in love. That's my language. Is this your field or do you just visit? M |

One of the best effects I've ever seen was Max Maven's "Mockingbird" effect on his "VideoMind" series. Unbeliveable. It's pert of the L and L series. I remember first seeing it and thinking there had to be a stooge helping him out.

There are some good tricks using the principle in the excellent Card Conspiracy Volume 1 by Duffie and Robertson.

"Double-Down", but of course I am biased.
The principle really IS a "thing of terrifying beauty..." Bryn

For those who like Mockingbird, check out Sal Piacente's "Memory Opener", which uses a similar approach.

LordPH, what do you do the times Mockingbird doesn't work? There seem to be a fairly big chance of it failing...
Ooops, I was thinking about The Hawk and now this post can only be edited but not erased. Please ignore. /Tomas |

Aunt Mary's Terrible Secret by David Williamson... I really like this one and the book is so entertaining that it's difficult to put down. You'll also find many, many effects and interesting references in the volumes of "The James File."
