Σ1 Ε1 – Mathematical Card Tricks
11 Οκτωβρίου 201830 λεπτάBegin the show with card tricks in which mathematics is clearly being used, but the secret is not easy to figure out. Learn the invariant principle: Some qualities stay the same in a deck even though the order of cards is changing. End with what Professor Benjamin calls the "tear-able" trick, being careful to use cards that you don't mind wrecking.Εγγραφή στο The Great Courses Living ή στο The Great Courses Signature Collection & Living ή αγοράΣ1 Ε2 – What's Your Deal?

11 Οκτωβρίου 201830 λεπτάProfessor Benjamin introduces a special guest, mathematician and magician Brent Morris, master of the perfect shuffle (also known as the faro shuffle), in which two equal halves of the deck are interlaced perfectly. You will learn two versions of this virtuoso technique (the in-shuffle and out-shuffle) along with sequences of shuffles that lead to very interesting symmetries.Εγγραφή στο The Great Courses Living ή στο The Great Courses Signature Collection & Living ή αγοράΣ1 Ε6 – Riffle Shuffles
11 Οκτωβρίου 201832 λεπτάExplore results of an ordinary riffle shuffle, where the deck is cut roughly in half, and the cards are interlaced approximately (but usually not perfectly). Depending on how the cards are arranged beforehand, intriguing effects are possible, based on Gilbreath's principle of patterned sequences. Study several of these magic showpieces.Εγγραφή στο The Great Courses Living ή στο The Great Courses Signature Collection & Living ή αγοράΣ1 Ε7 – Magic with Numbers
11 Οκτωβρίου 201835 λεπτάMaster an impressive medley of number-guessing tricks, involving the golden ratio, the Fibonacci series, and other notable numbers.
