The book Enumerative Combinatorics: Volume 2 by combinatorialist Richard P. Stanley contains a set of exercises which describe 66 different interpretations of the Catalan numbers.

Zero is probably the most misunderstood number. Even the imaginary number i is probably better understood, because it's usually introduced only to comparatively sophisticated audiences. The momentous introduction of zero metamorphosed the ancient Indian system of numeration into the familiar decimal system we use today.

The counting numbers start with 1, but the natural integers start with Keep counting each time the same event happens again and stop your timepiece when you reach "10", for this will mark the passing of 10 periods.

If you don't want to use zero in that context, just say something like "Umpf" when you first press your stopwatch; many do When applied to calendarsthis unambiguous tradition seems to disturb more people than it should.

Since the years of the first century are numbered 1 tothe second century goes from toand the twentieth century consists of the years to The third millenium starts with January 1, For some obscure reason, many people seem to have a mental block about some ordinary mathematics applied to zero.

Zero certainly qualifies as a multiple of two it's zero times two. Nevertheless, we keep hearing things like: Zero to the power of zero is equal to one! A related discussion involves the factorial of zero 0!

All constructible numbers are algebraic but the converse doesn't hold. Lindemann was the advisor of at least 49 doctoral students.

The three earliest ones had stellar academic careers and scientific achievements: The diagonal of a square of unit side.

At least one version of a dubious legend says that the man who disclosed that dark secret was thrown overboard and perished at sea.

The square of any fraction features an even number of prime factors both in the numerator and in the denominator. Diameter of a cube of unit side. Once the conjecture is made, the truth of the general theorem is fairly easy to establish.

A more pedestrian approach, probably used by Theodorus, is suggested below Let's present that weak argument, anachronistically, in the vocabulary of congruencesfor the sake of brevity: Therefore, my firm opinion is that Theodorus himself knew very well that his theorem was perfectly general, because he had proved it so Pheidias also created the sculptures on the Parthenonwhose architecture embodied the golden ratio, half a century after Pythagoras described it.

The letter e may now no longer be used to denote anything other than this positive universal constant.Mathematics Books.

This book presents a clear and comprehensive introduction to one of the truly fascinating topics in mathematics. Catalan numbers are named after the Belgian mathematician Eugene Charles Catalan (), who "discovered" them in , though he was not the first person to discover them.

The Mathematics Genealogy Project is in need of funds to help pay for student help and other associated costs. EugĂ¨ne-Charles Catalan has 3 students and descendants. Department of Mathematics. Empedocles of Acragas (c.

BC) Inventor of rhetoric and borderline charlatan.

His arbitrary explanation of reality with 4 elements (Earth, Air, Fire and Water) and 2 forces (Love and Strife) dominated Western thought for over two millenia.

Eugene Catalan studied mathematics and design in a university located in Paris. Eventually, he became an architect, just like his father. At the age of 15, he tutored and taught his fellow students how to solve geometry problems in school. + free ebooks online.
