MHF 3404, Notes 21 August We'll start with the ancient Greeks. The history of mathematics is a vast subject so we have to be selective. The ancient Greeks are the first modern mathematicians. In any event, that's how we trace our lineage. Euclid lived in Alexandria around 300 B.C. Not the one in Virginia, the one in Egypt. What's a Greek city doing in Egypt? Alexander the Great (356-323 B.C.) conquered a lot of territory. Alexandria is named after him. Euclid wrote The Elements . Mostly we think of him in connection with geometry, but there is a lot of number theory in The Elements also: the Euclidean algorithm, the infinitude of the primes, perfect numbers, and so on. There are two things that stand out to me in the geometry of Euclid: the notion of proof and the notion of construction (or algorithm). A proof is an argument that something is true. Euclid required that proofs start from things that were accepted as true and proceed step by step to the thing being proved. The accepted things are called axioms or postulates; the steps are called deductions. Of course the logic underlying the deductions has to be accepted also. Two of Euclid's postulates for geometry were Postulate 4 . All right angles are equal. Postulate 5 . If a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which the angles are less than two right angles.

To a mathematician, the statement embodies the beauty of algebra and its applications to geometry, hints at Galois theory, and is a rare example of a statement of the nonexistence of a solution. To recreational mathematicians, it is often thought of as a challenge. Every year, mathematicians around the world receive letters from the general population making claims to the contrary. Their solutions fall into two main categories: they either are false or do not adhere to the rules of constructions.

Mathematics Pronunciation Guide A Megametamathematical Guide, for the Diacritally Challenged, of the Proper American English Pronunciation of Terms and Names This guide includes most mathematicians and mathematical terms that may been encountered in high school and the first two years of college. Proper names are generally pronounced as in the original language. Some entries are obscure and may be useful only in a game of mathematical trivia, e. g. d'Alembert's mother, the name of the line in a fraction, or who shot Galois. I have not had the time to include most definitions or accomplishments. The curious person may try searching the internet for such information. However I have given a few, they are indicated with Move the curser to the symbol and wait a second. D ates include B.C. or A.D. only if the choice is not obvious from the context. The Guide is not complete, I will be adding more pronunciations and entries as time permits. (I did not give up my day job.) (The red dates and purple pronunciations are not links.)

50. The Quadratrix During the 19th century the French mathematician pierre wantzel proved that underthese circumstances the first two of those constructions are impossible http://cage.rug.ac.be/~hs/quadratrix/quadratrix.html

THE QUADRATRIX Trisecting an angle - Squaring the circle Introduction Three famous geometrical construction problems, originating from ancient Greek mathematics occupied many mathematicians until modern times. These problems are the duplication of the cube: construct (the edge of) a cube whose volume is double the volume of a given cube, angle trisection: construct an angle that equals one third of a given angle, the squaring of a circle: given (the radius of) a circle, construct (the side of) a square whose area equals the area of the circle. In the ancient Greek tradition the only tools that are available for these constructions are a ruler and a compass . During the 19th century the French mathematician Pierre Wantzel proved that under these circumstances the first two of those constructions are impossible and for the squaring of the circle it lasted until 1882 before a proof had been given by Ferdinand von Lindemann If we extend the range of tools the problems can be solved. New tools can be material tools (ex. a "marked ruler", that's a ruler with two marks on it, a "double ruler", that's a ruler with two parallel sides,...), or

[Conclusion] Text of the video: WHAT ARE WE PLAYING: TANGRAM OR MATH? C.Pellegrino - L.Zuccheri 1. What is Tangram? Tangram is an antique game that originally comes from China. It is formed by dividing a square into seven parts that are called "tan": a square, a parallelogram and five isosceles right-angled triangles, two big ones, a medium and two little ones. The traditional rules of the game are simple: you have to lay the seven tans on a plane, without overlapping them, trying to form a figure that reproduces, maintaining the proportions, the figures that you have seen earlier in the instruction book. It may appear very easy to play the game Tangram, especially if you see the pieces already assembled in a square, but normally a beginner has already difficulties to reform the square, after having taken the pieces out of the box. But Tangram isn't a puzzle as many others. After having played a little bit, you begin to enjoy the subtle elegance with which the square has been divided.

[Conclusione] Testo del video: A CHE GIOCO GIOCHIAMO: TANGRAM O MATEMATICA? C.Pellegrino - L.Zuccheri Il tangram è un antico gioco di origine cinese, ottenuto scomponendo un quadrato in sette parti dette tan: un quadrato, un romboide, e cinque triangoli rettangoli isosceli, di cui due grandi, uno medio e due piccoli . Le regole tradizionali del gioco sono semplici: si tratta di disporre sul piano, evitando sovrapposizioni, tutti i sette tan in modo da formare figure che riproducano, rispettando le proporzioni, quelle riportate in formato ridotto sui libretti che accompagnano il gioco. Giocare con il tangram può sembrare facile, troppo facile, soprattutto quando lo si vede già assemblato sotto forma di quadrato: normalmente però un principiante trova già difficoltà a comporre il quadrato, una volta tolti i pezzi dalla scatola.
