Review: Pi Book Test by Vincent Hedan

Reviewer: John Teo

The “Pi Book Test” is a book test without words.  For a start, it does not involve a book written with words.  Rather, it is a book featuring 10,000 decimals of π.

Although π is the 16th letter of the Greek alphabet, it is in conjunction with Mathematics that all of us learned about π in schools.  Π is the ratio of the circumference to the diameter of a circle.  It is a transcendental number, and has an infinite number of digits after the decimal point.  In schools, π is shorten to 3.142 or even to 3.14.

Vincent Hedan, the creator of the “Pi Book Test”, has come out with a book that contains “10,000 Decimals of π”.  What an interesting concept!  The book does not contain words but just digits after digits – supposedly, up to 10,000 decimals – of π.  Well, not exactly – other than the first page which contains the actual sequence of digits for π, Vincent Hedan has craftily recalculated all the runs of digits of π after that, so that it can accomplish all the effects designed for the book.

Just to show you how cunning and thorough Vincent is, he created an exact duplicate of this book that contains the actual 10,000 decimals of π, and has it listed on Amazon.com so that the public can purchase it.  And the compiler?  He names her Nina Chevendt, which is an anagram of his own name!  Full marks to Vincent Hedan for being so professional and dedicated to our art.

What effects can be performed with this special book?  Vincent Hedan has come out with a 3-phase routine.

First, the performer speaks about the attempt by many people to memorise the digits of π.  The recognized record by Guinness is up to 67,890 digits by Lu Chao of China.  A retired Japanese engineer, Akira Haraguchi, claimed to be able to recite up to 100,000 digits of π in 2006.

To show his prowess at memorizing the first 10,000 digits of π, the performer asks a spectator to name any page number.  He can tell the first 3 digits in that page.  He claims he has a photographic memory and can memorise all the digits found in any page.

In the second phase, he attempts something very much more difficult.  The spectator opens to any page and calls out a sequence of 5 digits from anywhere in that page.  The performer is then able to recognize this sequence and can recite each and every digit that continues from these 5 digits.  He recalls so many digits that the spectator has to turn the page to keep up with the performer.  This is truly an impressive demonstration of memory by the performer!

In the third and final phase, the performer remarks that since π has an infinite number of digits, virtually any sequence of digits can be found in it.  For example, a person’s identity number, credit card number, and even their birthdate can somehow be found somewhere in the digits of π!  To demonstrate this, the spectator states his or her birthdate.  The day and month are translated into a 4 digit sequence.  The performer is able to name the exact page, the line, as well as the position in that line where this exact sequence of digits is found!

If you cannot impress an audience with all these demonstrations, you should probably give up performing magic!  The actual π booklet of digits, the obsession in memorizing π, and the possibility of discovering a personalized sequence of digits in π, form an interesting premise for this effect.

There are no preshow work, no stooge, no sleight-of-hand and no pumping.  The secret is a special system developed by Vincent Hedan.  Kudos to Vincent for coming out with such a system that enables you to perform these three powerful effects!

You have to spend some time memorizing and master the system, much like memorizing a stacked deck of cards.  Speaking of stacked decks, Vincent has versions of the Pi Book Test that are based on the Tamariz’s Mnemonica stack, or the Aronson stack, or the Osterlind stack or even the Nikola stack.

What you receive is the “stackless” version of the π book, which utilizes his own system, and a link to download the instructions in pdf format.  If you want the other stacked version, you will have to contact Vincent Hedan directly.  

There is also a free app for your smart phone developed by Jerome Damien for you to practice the effect before actually performing it in front of a live audience.  The instructions will tell you how to obtain it.

The instructions by Vincent Hedan contains important patter and valuable performance tips that help you to make the effect more impactful to the audience.

If you take the trouble to practice and master the system, you have a killer effect in your hands.
