ON THE PRINCIPLES AND DEVELOPMENT OF THE CALCULATOR Babbage, Charles

On the Principles and Development of the Calculator and Other Seminal Writings by Charles Babbage and Other.
Edited and with an Introduction By Philip Morrison and Emily Morrison
Crackpot to his contemporaries, genius to modern scientists, Charles Babbage (1792-1871) was the true discoverer of the principles on which all modern computing machines are based; but his time received his work with scorn, and his name has been virtually forgotten until recently. This original Dover publication is now the only complete story available of the life and work of this amazing mathematician-philosopher-inventor.
Part I consists of selections from Babbage's long-out-of-print autobiography, "Passages from the Life of a Philosopher." In his own unrestrained and "somewhat peculiar" way (Encyclopaedia Britannica), Babbage tells the lively story of his youthful escapades, his warm friendships (and embittered enmities) with such outstanding European figures as Laplace, Biot, Humbolt, and Sir Humphry Davy, and the dominating obsession of his life -the creation of a machine that would forever remove the mistakes and wasted effort inevitable in any extensive arithmetical calculations.
His dream has only now come true, but to convince yourself that Babbage was indeed far ahead of his time, turn to the articles by the inventor and by his contemporaries that explain the principles and operation of his brilliant -but never completed- calculating machines.

COLECCÔES DO MUSEU MONOGRÁFICO DE CONIMBRIGA Moutinho Alarcao, A.

Frequentemente o vistante de Conínbriga avança duas perguntas cuja resposta é difícil e incerta: quantos habitantes tinha a cidade; donde ihes vinha a riqueza?

Nem a epigrafia, nem o estudo dos monumentos e das casas já descobertas, nem as dimensoes aproximadamente conhecidas do anfiteatro, nem o cálculo da água que o aqueduto podia distribuir diariamente, sugerem valores demográficos. Pelo contrário, nao é difícil imaginar a composiçao desta sociedade, formada maioritariamente por uma populaçao indígena que latinizou os seus nomes e adoptou a cultura romana mas permaneceu livre e fiel às suas raízes célticas. Era esta populaçao quem garantia a força do trabalho agrícola e artesanal, era ela ainda quem detinha a maior parcela da propriedade e do poder económico, ao lado das familias de origem itálica -que constituiam de preferência os quadros jurídicos e administrativos- e dos escravos e libertos, indispensáveis componentes do tecido social romano.

LIFE IN RURAL AMERICA

National Geographic 1974
Frogs croaking in the night. It is a sound we learn to live without in the city, but it can instantly summon a flood of memories of a country childhood... "In the pages of Life in Rural America, five writers and more than a score of photographers cross the United States visiting farms, ranches, and small towns -"Home" for millions of Americans no matter where they live now. In these surroundings old customs and traditional values linger alongside changes wrought by mechanization, new highways, and modern communications.

THE DEVELOPMENT OF MODERN CHEMISTRY Ihde, Aaron J.

Over the past two centuries chemistry has developed from germinal speculations on the nature of gases and minerals to a hoghly complex discipline encompassing munerous areas of study. This authoritative and comprehensive volume traces the historical development of chemistry from its roots in ancient Greek theory to the revolutionary and explosive discoveries of the 20th century.The author, Professor Emeritus of Chemistry and History of Science at the University of Wisconsin, places the role of alchemy as a "precursor" to chemostry in perspective -he reveals that chemistry inherited just as much from medicine and technological arts. This book also shows how discoveries concerning gases in the mid-18th century were pivotal in creating the foundations of chemistry as a modern science.

ABC FOR BOOK COLLECTORS Carter, John

Not only is the actual language of book-collecting full of jargon and special terminology. The rules, conventions and taboos of the cult are also legitimately puzzling to the layman, and its technique involves many unsuspected subtleties. Here, under about 450 alphabetical entries, ranging in length from a single line to several pages, may be found definition and analysis of the technical terms of book-collecting and bibliography, interspersed with salutary comment on such subjects as auctions, condition, facsimiles and fakes, "points", rarity, and the like.
This is an essential reference book for every book collector, from aspirant to addict. It belongs on the private shelf of all but the most omniscient of librarians and antiquarian booksellers. And it will entertain any general reader who relishes the niceties of connoisseur-ship for their own sake.

EL MUSEU D'ART DE CATALUNYA Farré i Sanpera, M.Carme

Si haguéssim de fer un recorregut per la nostra histia, un dels camins ens duria al Museu d'Art de Catalunya, on es recull i s'exhibeix la creació plàstica dels homes que foren coprotagonistes del naixement, de la configuració, de l'establiment i de l'expansió d'una nació.
Les colleccions d'art romànic aplegades al Museu constitueixen el més important conjunt existent al món i el fan, per tant, museu únic i indispensable per a qualsevol persona interessada en l'Edat mitjana. El fet de comptar amb la major i més completa quantitat d'obres aplegades d'aquest període de l'Occident implica, naturalment, la presència d'algunes peces que converteixen el Museu en primera collecció mundial, pel que fa a la singularitat i la bellesa d'aquestes.
