Hardback. Condition: New. An illustration-packed dive into the geometry, engineering, and physics of soccer ballsThe Football takes readers on an entertaining and fact-filled exploration of the mathematical secrets of the most popular spherical object on the planet. The football is familiar to billions of fans across the globe, but how many really look at it? Do footballs all have the same shape? Spoiler: not exactly. How does their shape affect how they play? With Étienne Ghys as our guide, we discover why ballistics, friction, and air flow are key to scoring goals-and why the football is a mathematical problem that engineers are still trying to solve.Ghys begins with the classic Telstar ball used in the 1970 World Cup in Mexico. Its twelve black pentagons and twenty white hexagons are what most of us picture when we think of the sport. Following the story through successive World Cups, he shows how engineers constantly challenge themselves to reinvent the ball, aiming for a perfect sphere while accounting for manufacturing requirements and aerodynamics. Along the way, Ghys introduces us to the mathematics of Platonic solids, symmetries, polyhedra, turbulence, roughness, drag, and spin. He paints engaging portraits of the engineers and sports insiders who study and apply these phenomena and explains how the skills of players factor into how the ball behaves, whether the game is being played in stadiums, schoolyards, or backyards.Featuring a wealth of color illustrations, The Football blends a lively narrative with insights from a world-renowned geometer to tell a mathematical story unlike any other.…

Couverture rigide. Condition: Très bon. #Relié : 159 pages #Parution : janvier 2013 #Résumé : Que peuvent bien avoir en commun des phénomènes naturels aussi que différents que l'agencement d'une graine de tournesol, l'élégante spirale destinée par la coquille de certains mollusques et les bras de la voie lactée? Quelle règle géométrique d'une inégalable harmonie se cache dans l'oeuvre des plus grands artistes, de Vitruve à Salvador Dali et de Vinci à le Corbusier? Aussi incroyable que cela puisse paraitre, la réponse a ces deux questions réside dans un simple nombre. Un nombre d'humble apparence, connu depuis l'antiquité et dont la présence remarquée dans les représentations artistiques et naturelles lui valut l'appellation de "nombre d'or" ou de" divine proportion" Chargé de plus de 2000 ans de mathématiques et d'autant de réflexions sur l'harmonie et des liens qui unissent les nombres et notre perception de l'espace , le nombre d'or n'en finit pas de nous fasciner.…
