I was wondering if anyone here uses it, and where can I read and learn about it?
Message: Posted by: Scott F. Guinn (Jan 9, 2002 02:36PM)
Unfortunately, the original manuscript describing it in detail has been out of print for sometime. There are a number of individual routines using it.

You'll find some in:



Duffie's "Effortless Card Magic"

"The Card Magic of Nick Trost"

"Off The Wall" by Ben Harris

Max Maven's tapes and books



This is by no means a complete list, just somewhere to start.

"It is a thing of terrifying beauty," as Max Maven puts it. I first learned of this principle in Maven's VideoMind series in a trick called the "Mocking Bird." What a sweet principle! Spectators may shuffle your stack, which is so convincing. There is a book out by Steve Mayhew and Jack Carpenter called ANGELS MAY SHUFFLE BUT THE DEVIL STILL DEALS. This book is solely dedicated to the Gilbreath principle. H&R BOOKS carries it, but they are out of stock.

Lonnie,



A couple years ago, I wrote a short article that explains how the Gilbreath Principle works. Check your email. If anyone else is interested, drop me a line and I'll email it to you.

I'd also like to second the earlier recommendations
to MacTier's "Card Concepts". Apart from giving one
of the best explanation I've ever read to why and how the principle works you also get in all 35 different routines using this thing of terrifying beauty !

When tired of that you can test some of the other
29 or so principles in the book...

I don't recall the details of the effect - it's been a long time since I've seen the tape - but the general answer (to shuffling more than once with Gilbreath effects) is: "No."

If you read and understand Spanish, a book you must have is Woody Aragon´s "Cosas Mias".

He is a great young cardician from Madrid, specialized in card magic involving mathematical principles. He has routines which are real miracles, and have a great study about the Gilbreath Principle, and what he called, "the new" Gilbreath principle (more or less new applications of the old one, and the combination of this principle with others).

All the best magic,

Is this where a spec shuffles the deck and every 4 cards in line are different suites and stuff?
Someone showed it to me and I went over it over and over again and I understand completely now :)
Message: Posted by: Vernest (Nov 4, 2004 11:03PM)
Epilogue magazines(issues 4, 5) covered a lot of the principle. I believe it was issue 4 that had a lot of riffle shuffle setups for the principle as well as effects. Roy Walton has material on this as well, so if Roy has work, I bet Duffie has some as well. As a matter of fact, I bet he has some good ones.

Fulves published some of this as well, and J.W Searles, Gene Finnell, and well...Norman Gilbreath obviously has a lot of it.

I remember Marlo had some effects with it as well. The one I can remember is where all the cards are taken out two at a time and shown to be red/black, but the ones that are not endup being the selections.
Message: Posted by: Kephri (Nov 5, 2004 01:16AM)
Apart from the sources already mentioned

Take a look at the Semi-Automatic books by Steve Beam, he has some great, comical uses for the Principle I think you would enjoy.
Message: Posted by: chiz (Nov 5, 2004 04:55AM)
This principle is actually pretty straightforward if you think about it. If you have a packet of 10 cards in some order, all of different value, and another packet, in the reverse order. If you shuffle them together in any order, you will still have 10 cards of different value on the top half, and the same on the bottom. Just think about the top card of the reverse pile: If you shuffle the deck, and the only card from the reverse half enters the top half, then that will mean that the bottom card from the top half will now be in 11th place (and not in the top half), that card will be of the same value as the new card in the top half.
The same argument can be used for all the cards....
I hope someone understood that.

Ben

ps. Try understanding the mechanics and stability behind throwing a spinning playing card- that's much more difficult!

Chiz's explanation is about one case of the stack. His stack is [abcd] and [dcba] type which is a particular one called Reverse Stack.

If you learn the principle more preciously, you will find more possibility in using the principle.

Is this principle a theorem or an axiom, i.e. can it be mathematically prooved based on other priciples, or do we just "accept it" like 1+1=2? If it is proovable, can somebody post a proof?

PS: chiz, you put "shuffle" in your post. I don't think it's exact. With an overhand or hindu shuffle, as opposed to a riffle or faro shuffle, I am not sure the principle works.

The Gilbreath principle was first published in the 1959 Linking Ring, not sure of the month. It won trick of the year.
Message: Posted by: Hideo Kato (Nov 5, 2004 08:13PM)
Proof of Gilbreath Principle is very easy. My method of proof is as below.

First of all, you must know Riffle Shuffle is same as taking cards from two packets in random order and pile the cards in one packet face up.

You have Stack-1 with repeating of 1$B!D(Bn. For example, c,h,s,d,c,h,s,d,c,h,s,d,,,,,,.
You have Stack-2 with repeating of n$B!D(B1. For example d,s,h,c, d,s,h,c, d,s,h,c,,,,,,.

If you take n cards from two packets, you can$B!G(Bt take any duplicates, so you will have each of 1$B!D(Bn cards.

After taking n cards, two remaining packets becomes a reverse stack each other again, so you always take each of 1$B!D(Bn cards if you take next n cards.

That$B!G(Bs it.

I was completely fooled by Max Maven's The Hawk and The Mockingbird. I know he has a series of routines that he treasures called the Birds of Prey, most of which remain unpuplished I think. I wonder of they all involve the Gilbreath Principle in some way.

There's also a very nice trick using cards with the alphabet from his friend, Phil Goldstein's book, Redivider. It uses the principle to force a word which can be revealed in almost limitless creative ways.

Personally, I'm not fond of the Dragon's Pearl. On the one hand it's a great premise, but I think that when you deal through the entire deck and show that they all come out in a convenient matching sequence that it just screams mathematical principle and not magic. (I'm not sure if it's just me. Maybe I give spectators too much credit).

I will say though that I love the way Lennart Green produces random (often large) objects from the middle of the deck. Does anybody know of a method for doing this while standing?
Message: Posted by: Nosher (May 12, 2006 06:32PM)

In Lennart Green´s excellent Dragons Pearl the spectator shuffles the cards before the effect occurs, how can yo say it scream mathematical???
I think it looks extremely fair. Yes, if the deck was unshuffled I would think it was a stack.

It's hard to explain why without exposing it, but Mockingbird allows multiple shuffles. The initial shuffle takes advantage of the Gilbreath Principle to put the deck in a certain state. The deck can then be divided into packets in such a way that multiple shuffles are allowed, because they are irrelevent. It's a great, great routine.

I agree with Mats Kjellstrom about Dragon's Pearl. While it may seem to be mathematically based, the combination of the Gilbreath Principle and the legitimate Rosetta Shuffle, done by the spectator is going to fly by 99 out of 100 lay people. All of the coincidences which follow are just inexplicable. And, tying this to a kind of theraputic procedure which combines a sort of fortune telling with healing powers is especially good for ladies, which Lennart points out. This is not the kind of thing you can do everywhere, but in the proper setting, you could start a religion based on it.

Don't play it like a card trick... it transcends that. Do it as some kind of Eastern psychological cleansing process or healing procedure and they will talk about it for the rest of their lives.

Edh, Dragon's Pearl can be found on Lennart Green's "Green Lite" DVD, from A-1 Magicalmedia.


I remember when I first moved to Las Vegas, and began attending Gary Darwin's Midnight Magic Club. At one of those early meetings, I joined a group of people who were performing, and then teaching, routines.

When it came to be my turn, I performed and taught Terry LaGerould's "Best Bet Yet", which depends on the Gilbreath principle, and explained the trick. I tried to explain the Gilbreath principle as best as I could, and then the rest took their turn.

Later that same night, I was talking to Gary Darwin, and he introduced me to an older gentlemen, who had been at the table earlier that evening, but whose name I never learned. Gary said, "Scott, meet Norman Gilbreath!" :wow:

I can now honestly say that I'm the man who taught the Gilbreath principle to Norman Gilbreath. Sure, it was decades after he made it famous, but . . .

I love Lennart Green's very visual explanation of the Gilbreath principle on his "Green Lite" DVD. He uses his outstretched fingers and it really clarifies it... at least for me.

However, don't worry too much about it. There are countless marvelous effects based on GP and you can do them even if you are clueless as to why the principle works.

Message: Posted by: Lawrence O (Mar 20, 2009 02:29AM)
The two Gilbreath principles often referred to (including by Norman Gilbreath) are actually two ways of looking at only one principle. The initial principle is just a less sophisticated use of the “second” which encompasses the principle more thoroughly. The magnetic colors principle was based on the fact that we have 26 red cards, and 26 blacks, therefore, if we have cards of opposite colors, we have both piles in reverse order in terms of color. Gilbreath later realized this but, by then, the concept of two principles had travelled around the world. Max Maven has done a lot to try and set things straight, but people still talk about a "second" principle. Gilbreath's so-called second principle is not, as sometimes claimed, an expansion from a few cards to sets of any size: a set with two colors is the same as a set with two or more numbers. The “second principle” is a specific instance where the set is the full size of each of the packets shuffled into each other. Thus, since the size of the set doesn’t constitutes a change, there is actually no second principle. The principle, as Gilbreath himself later realized, applies to sets of any size. If we are using a set of two, we are using the Gilbreath Principle; if we are using a set of five or a full deck, we are using the Gilbreath Principle. The only technical extension to the Gilbreath Principle was made by the French mathemagician Daniel Péris. However any talk about a first and a second principles could only create confusion.

"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.

Great post(s) Lawrence. ...As usual.

I recently received a copy of Reinhard Müller's "Gilbreath's Principles" and would recommend it, without hesitation, to anyone with an interest in the principle(s). In addition to the history and material contained in the notes, the appendix boasts a valuable (and sizeable) bibliography listing tricks from a wide variety of contributors, and identifies the sources in which they were published. This will keep me busy for quite some time.

I am fascinated by this principle and its use in card magic. A lot of the tricks are "self-working" using the principle, but seem to involve shuffling or dealing the deck out into piles or packets.

What tricks use the principle but come across as the least mathematically-based or self working principle. I love shuffle bored for example, but I think a lot of people realize it is not based on sleight of hand but some sort of principle. Regardless, it is real entertaining and they love the effect.

What tricks best "disguise" that they are based on the Gilbreath principle?
Message: Posted by: Lawrence O (Apr 20, 2009 11:24AM)
Hi Redeagle

Do you think that "mathematically-based or self working principle" should be "disguised" to appear as "based on sleight of hand" or wouldn't you like them to appear as achieved by magic?

If you want "mathematically-based or self working principle" to look magical, do the lay out during the presentation and simply give a magical cause at the magical moment like "casting a shadow" as you wave your hand over the cards or offering a magical phrase like "... and like a ghost gets through the walls of an ancient castle..." or both (giving, by the same token, a tribute to Michael Ammar Charlie Miller and Albert Goshman)

I invented a shuffling to the aces effect which involves the Gilbreath principle, Sort of. Basically, the specator's shuffle to the aces.

In effect: the performer shuffles the cards and the top card is an ace. The spectator then shuffles the cards and the top card is an ace. This is repeated again. The last ace is chosen out of 49 and it turns out to be the ace. After this, I go into a four ace/gambling routine.

I am not aware yet of the content of this Reinhard Müller's book, but being familiar with other things that he studied, I can highly recommend with my "eyes wide shut" to look with open mind at whatever he wrote on this subject as well. Reinhard is a very smart scholar (amongst other things).

Earlier in this thread (2004) Kephri claims there is about 29. Not all of them are equally useful and McTier only gives one or two examples for each principle, except for Gilbreath were he gives about 30...
