Here's yet another cool mathemagical principle!
Check out Lewis Jones' "The Pattern Principle" in Steve Beam's "Semi-Automatic Card Tricks, Vol. 3". The principle itself isn't a math principle, however, it would be next to impossible for it to work if the mathematics of it weren't worked out properly. Basically, it minimizes the work required to remember the order of the colors in the deck. One read through the principle, and the included effects, "Red Alert 1, 2, 3 & 4," and I was well, like this: There's some great & unexplored potential in the "Pattern Principle". |

Here's a mentalism effect from Buckley's Gems of Mental Magic that uses a math idea that very few know. The effect, called Devious Digits as described by Buckley:
Here is a miracle in which a number that runs into the quintillions is reached by multiplication of a random selection of numbers. Yet a spectator who calls a friend of the performer by telephone is given this long number accurately while it is being worked out by the assistant in the room. The multiplication involves a 15-digit number times any number from one to thirteen. While the first number is not really random, the second is freely selected. It's a killer! landmark Another favorite old-time gag is the Piano Card Trick from Royal Road. Though simple, it's amazing how many people you can fool with it if you present it as a sleight of hand trick. landmark

There's a similar use of this principal used by Roger Curzon (from Sheffield's Magick) in his booklet "Blood on the Tricks". Effect is - a spectator 'shuffles' a packet of 9 differently numbered cards; - 1 or 2 spectators randomly generate a number using a calculator The 9 cards when dealt out form the 9 digit number generated. Not a math effect per se, but very powerful - can be dressed up as either (im)probability of events occurring, the power of the subconscious etc, etc... Cheers |

Lately I've been doing a lot of work with Bob Hummer's "3 object divination" principle. It's very versatile. A good description is in Bill Simon's Mathematical Magic book.

There's a trick in Scarne on Card tricks, with a name I don't recall, that's very good. The spectator shuffles the deck. Upon getting it back, you ribbon spread it face up and get a quick look at the third card from the bottom as you show that the cards are well mixed. Now write a prediction and keep it face down on the table, which names this card. Have someone reach into deck and pull out any ten cards (except for the bottom 3). Now mix those ten up and have someone pick any 4 of them & turn them face up. Now if you can, for each of those 4 cards transfer enough cards from the top to bottom to make each one equal ten. E.g., if a 3 shows, transfer 7 cards to the bottom, if a 10 or face card shows, don't transfer any. If you can do this without visibly counting so much the better, but sometimes I do it openly. Then look at the 4 cards that were selected from the 10. Add their values. Openly deal that number face up but stop when you get to the number and hold that card face down. Turn over your prediction and show it. Now turn over the card. They will match.

Does anybody else use Gardner's cube root and fifth root 'calculations'? I find people seem to enjoy these as an amazing demonstration of memory. (I don't present them as lightning calculations, but instead patter about how I have been honing my memory by memorizing tables of roots.) I usually precede this with some actual easy calculations of squares of 2-digit numbers ending in 0 or 5.

Cube and fifth root are great demonstrations especially to an audience who is more mathematically oriented.
If you can do other mental calculations using logarithms for instance, it absolutely kills. |

By far the best trick using mathematics is to be found in the “Royal Road to Card Magic”, page 148 and is called “An Incomprehensible Divination.”
It kills laymen and some magicians. I have used it for years. |

See my Oct 11, 2003, 11:21pm post. I don't believe they're still in print, but you can find them if you hunt. Keep your eyes peeled towards Lybrary.com, in order to find the upcoming electronic versions of them.

One that hasn't been mentioned but I've been utilizing for some time is Osterlind's Breakthrough Card System (if that qualifies).

Aronson's Undo Influence card principle is one of those principles that even when you try it out for yourself, you fool yourself. It seems it can't possibly work--yet it does, every time.

I used to do the cube root thing in my first performances - I forgot if I learned it from Kaye or Corinda.
While some mention Hummer's 3 object divination, I found that the next effect in Gardner's "Math, magic and mystery" more to my taste. It was Yate's FOUR object divination, using disguised parity or binary switching. I've used it over the phone (once on a friend's girlfriend who just HAD to call me after she participated in one of my shows!) The end effect is that I have them hold their hands over two, last objects (i.e. coins) and I can mysteriously tell them under which hand their previously chosen object is! She freaked!

My favorite principle is the principle of restricted choice, which relates to bridge, not to magic. It's based on a similar idea to the old "Let's Make a Deal" show. Briefly: Three closed doors; behind one is a new car, behind the other two are rocks. After you pick a door, you're going to be shown a rock. So, you pick your favorite door. Before you get to see what's behind the door you chose, the host shows you a door you DIDN'T pick, and behind it is...a rock. Now, you may keep your original choice, or switch for the other unopened door. Better to keep the first choice, to switch, or is it a toss-up? If you're unfamiliar with this problem, it can be very counter-intuitive. It has strong practical application at the bridge table.

Guess they forgot to tell Bill Buckley. "...as we reason and love, we are able to hope. And hope enables us to resist those things that would enslave us." |
