A university professor of mathematics takes on tricks based on math.
From the preface:
As mathematics is (or was) my profession and magic my hobby, I was always interested in tricks that combined both, notably tricks with pure numbers. ... Unfortunately, I soon noticed that in most of the so-called mathemagical tricks there was very little mathematics and even less magic! What people use to call "mathematics" are mostly extremely simple arithmetical facts, and if you plodded through the tricks with numbers they proved to be excessively boring.
I do not know if I have succeeded to get around this deplorable state of affairs with the six or more tricks I offer in these Lecture Notes. They all depend on mathematical facts that are not altogether trivial and they lend themselves to good presentation which is of course essential for any magical idea. They all use simple props which (with the exception of the padlock in Chapter 2) can be made up without any difficulty.
