Il libro egrave; dedicato ad unrsquo;esposizione delle tecnologie monetarie ed analizza le varie tipologie di errore di coniazione che si possono verificare in questo delicato processo. In particolare; nella prima parte del libro; viene approfondita lrsquo;evoluzione delle tecniche di coniazione dalla nascita della moneta sino allrsquo;introduzione dellrsquo;euro; con una descrizione dettagliata del moderno processo di coniazione delle monete destinate alla circolazione. Solo dopo aver appreso i concetti base di tale processo egrave; infatti possibile analizzare nella seconda parte del libro i singoli errori; illustrandone le varie cause ed effetti.Il collezionismo degli errori di coniazione egrave; unarea della numismatica con altissimi potenziali di crescita e ormai numerosi collezionisti si cimentano ogni anno in questa affascinante nicchia della numismatica. Tuttavia; spesso a causa delle pochissime informazioni a disposizione; questo collezionista non comprende fino in fondo le varie forme di errore; non capisce lorigine di tali errori e non sa riconoscerne lautenticitagrave;. Per questo motivo; prima di investire in errori di coniazione; egrave; fondamentale investire in conoscenza per cercare di trovare le risposte ai numerosi dubbi che possono sorgere. Solo una volta appresi i concetti base che consentano di riconoscere gli errori autentici da quelli artefatti e di distinguere un errore raro da uno comune; saragrave; possibile avviare una collezione che potenzialmente non ha limiti!

A mathematicians guide to great architectureBy Joe P.I have used this book as the textbook for a study-abroad class I teach in Rome (Mathematical Beauty in Rome; a UCSD Global Seminar) on the architectural geometry and structural engineering of Roman monuments. Prof. Hahn has given us a wonderful book - clear and carefully written; wide-ranging; mathematically sophisticated - with discussions and problems that will challenge students in engineering and mathematical disciplines. Aside from its value as a textbook; it is a pleasure to read for any technically-minded person; especially if you have a passion for architecture. My advice: read the book; and then take a trip - your own "mathematical excursion" - to visit the sites (with book in hand) that are discussed; and you will have a uniquely delightful travel experience.Note: I have both hardcover and Kindle editions - both are well done.0 of 0 people found the following review helpful. Interesting excursions!By BJOslash;RN FELSAGERAny book trying to bridge mathematics and architecture in a historical perspective is most welcome; and Alexander Hahn has certainly collected some very interesting examples and succeeded in putting them into an appropriate perspective. Unavoidable he has had to make some simplifications but he is not always making them clear to the reader. E.g. he is making an assumption about Utzons sail that is only approximately fulfilled and only for the second sail. The point A does not have the same height as the center of the sphere as is clear from Yuzo Mikamis illustration on the same page and therefore you cannot rotate the sphere so that A lands on the y-axis. But apart from such minor nuissances I really enjoyed reading the book!1 of 1 people found the following review helpful. whew; didnt realize i nedded a masters degree in mathBy Hencha friend; who is also an architect; told me of this book and said it was fascinating. got the book and am also fascinated by the whole concept. it was written by an obviously talented mathematician who apparently thought advanced math was understood by a typical reader. his writing is clear and logical and; with much effort; i can sort of follow his concept. i am constantly amused by his elegant formulas and derivations that look like no formulas i have ever seen. bottom line: better be real good with math to fully enjoy this book.
