The study of the vocabulary of the Catholic religion may be taken as a definition of the liberal arts. Origins of Catholic Words is a work of reference organized like a lexicon or encyclopedia. There is an entry for each word of importance having to do with the Catholic Church. Anthony Lo Bello gives the etymology of the word, describes what it means, and then adds whatever further discussion he feels is needed; in some cases this amounts to several pages. Lo Bello has assembled, over a number of years, lucid and wide-ranging remarks on the etymology and history of the words that occur in the study of the Catholic religion. A true labor of love, this sophisticated, one-of-a-kind dictionary will delight those who take pleasure in learning. Anyone interested in words and language-indeed, in culture, will find something interesting on every page. This is a book one may read and not just consult. The author has been ecumenical in his choice of authorities. J. B. Bury, Lord Chesterfield, Mandell Creighton, S. R. Driver, Ferdinand Gregorovius, Dr. Johnson, Henry Charles Lea, Bishop Lightfoot, Thomas Babington Macaulay, John Stuart Mill, Henry Hart Milman, Leopold von Ranke, and Bertrand Russell find their places alongside Alban Butler, Denzinger, Ignaz Doellinger the Abbe Duchesne, Adrian Fortescue, Bishop Hefele, Cardinal Gasparri, Msgr. Ronald Knox, Msgr. Horace K. Mann, John Henry Newman, Ludwig von Pastor, Wilfrid Ward, William George Ward, and Evelyn Waugh. There have been many changes in the Catholic Church since 1962, and one of the goals of this book is to describe what will soon be missing from the memories of all living people. The Origins of Catholic Words may, Lo Bello hopes, make its small contribution so that the situation not arise, which would convict John Henry Newman of error when he wrote, "What the Catholic Church once has had, she never has lost."

Gaudiopolis (The City of Joy) was a pedagogical experiment that operated in a post-World War II orphanage in Budapest. This book tells the story of this children's republic that sought to heal the wounds of wartime trauma, address prejudice and expose the children to a firsthand experience of democracy. The children were educated in freely voicing their opinions, questioning authority, and debating ideas. The account begins with the saving of hundreds of Jewish children during the Siege of Budapest by the Lutheran minister Gabor Sztehlo together with the International Red Cross. After describing the everyday life and practices of self-rule in the orphanage that emerged from this rescue operation, the book tells how the operation of the independent children's home was stifled after the communist takeover and how Gaudiopolis was disbanded in 1950. The book then discusses how this attempt of democratization was erased from collective memory. The erasure began with the banning of a film inspired by Gaudiopolis. The Communist Party financed Somewhere in Europe in 1947 as propaganda about the construction of a new society, but the film's director conveyed a message of democracy and tolerance instead of adhering to the tenets of socialist realism. The book breaks the subsequent silence on "The City of Joy," which lasted until the fall of the Iron Curtain and beyond.

During the fifties, one of the authors, G. Stampacchia, had prepared some lecture notes on ordinary differential equations for a course in ad analysis. These remained for a long time unused because he was no vanced longer very interested in the study of such equations. We now see, though, that numerous applications to biology, chemistry, economics, and medicine have recently been added to the traditional ones in mechanics; also, there has been in these last years a reemergence of interest in nonlinear analy sis, of which the theory of ordinary differential euqations is one of the principal sources of methods and problems. Hence the idea to write a book. Our text, based on the old notes and experience gained in many courses, seminars, and conferences, both in Italy and abroad, aims to give a simple and rapid introduction to the various themes, problems, and methods of the theory of ordinary differential equations. The book has been conceived in such a way so that even the reader who has merely had a first course in calculus may be able to study it and to obtain a panoramic vision of the theory. We have tried to avoid abstract formalism, preferring instead a discursive style, which should make the book accessible to engineers and physicists without specific preparation in modern mathematics. For students of mathematics, it pro vides motivation for the subject of more advanced analysis courses."

Do you ever wonder about the origins of mathematical terms such as ergodic, biholomorphic, and strophoid? Here Anthony Lo Bello explains the roots of these and better-known words like asymmetric, gradient, and average. He provides Greek, Latin, and Arabic text in its original form to enhance each explanation. This sophisticated, one-of-a-kind reference for mathematicians and word lovers is based on decades of the author's painstaking research and work. Origins of Mathematical Words supplies definitions for words such as conchoid (a shell-shaped curve derived from the Greek noun for "mussel") and zenith (Arabic for "way overhead"), as well as approximation (from the Latin proximus, meaning "nearest"). These and hundreds of other terms wait to be discovered within the pages of this mathematical and etymological treasure chest.
