Extractions: zpracovali: Jiøí Svrek, Roman Barto Typografické poznámky k matematickým vztahùm jsou uvedeny na konci tohoto textu. 4. Historie èísla p Ve Starém zákonì v Bibli lze nalézt zmínky, napøíklad pøi popisu velkého chrámu krále alamouna postaveného kolem roku 850 pø.n.l, z nich vyplývá, e èíslo p bylo odhadováno èíslem 3. Egypané a obyvatelé Mezopotámie odhadovali èíslo p hodnotou 25/8 a (10). Na obranu alamounových øemeslníkù je tøeba uvést, e pøi stavbì chrámu byly pouívány velké kvádry kamene, pøi jejich usazování na místo nebyla nutná velká pøesnost. Skuteènost, e pomìr délky krunice k jejímu polomìru je konstantní, byla známa velmi dlouho. První odhady èísla p byly získány mìøením, jako v pøípadì "biblické" hodnoty 3. V egyptském papyru, který objevil A. Henry Rhind je odhad èísla p dán èíslem 4.(8/9) První teoretický výpoèet èísla pí pochází od Archiméda ze Syrakus (287 - 212 pø.n.l.). Archimédes získal odhad p Archimédes vìdìl, e èíslo pí není rovno 22/7 a netvrdil, e objevil pøesnou hodnotu. Jeho nejlepím odhadem je 3.1418, jeho chyba je asi 0.0002. Archimédes pro odhad èísla p pouil metodu vepsaných a opsaných mnohoúhelníkù krunici s jednotkovým polomìrem. Nalezl vztahy pro odhad èísla pí pomocí obvodù tìchto mnohoúhelníkù a nalezl iteraèní vztahy mezi obvody n-úhelníkù a (n+1)-úhelníkù.

Extractions: The following list is given in reverse chronological order. It is a representative sampling of the talks that I have given in the past decade, not the complete list. Duplicates have been consolidated and some talks have been omitted entirely. Talks given in 2002: "A Reader's Guide to Euler's Introductio," Euler 2K + 2 Conference. Countdown to the Tercentennary , Rumford Maine, 4-7 August 2002. Leonhard Euler's Introductio in analysin infinitorum is surely one of his most famous works. For a century after its publication in 1748 it was widely read by aspiring mathematicians. Today, thanks to John Blanton, it is available in English translation. To encourage aspiring historians to read this famous work, a reader's guide will be distributed. It will summarize the contents of the individual chapters of the Introductio , explain points that the reader might miss, point out antecedents of the work, and detail how the work influenced later mathematics.

Extractions: by Kim Ives PHOTO: Leon Romain has devised a theorem for trisecting any angle, one of geometry's great puzzles. If he is right, it could change your life. So far, nobody has proved him wrong. Around 450 B.C., the Greek mathematician, Hippias of Ellis, began searching for a way to trisect an angle. Over 2000 years later,in 1837, a French mathematician named Pierre Wantzel proclaimed that it was impossible to trisect an angle using just a compass and a straightedge, the only tools allowed in geometric construction. But now, at the dawn of the twenty-first century, a Haitian computer program designer, Leon Romain, claims he has proven,with a "missing theorem," that it is possible to trisect an angle with those simple tools, disproving Wantzel's assertion and exploding centuries of mathematical gospel.

Extractions: 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.
