Leonhard Euler

by Ronald S. Calinger

This is the first full-scale biography of Leonhard Euler (1707-83), one of the greatest mathematicians and theoretical physicists of all time. In this comprehensive and authoritative account, Ronald Calinger connects the story of Euler's eventful life to the astonishing achievements that place him in the company of Archimedes, Newton, and Gauss. Drawing chiefly on Euler's massive published works and correspondence, which fill more than eighty volumes so far, this biography sets Euler's work in its multilayered context--personal, intellectual, institutional, political, cultural, religious, and social. It is a story of nearly incessant accomplishment, from Euler's fundamental contributions to almost every area of pure and applied mathematics--especially calculus, number theory, notation, optics, and celestial, rational, and fluid mechanics--to his advancements in shipbuilding, telescopes, ballistics, cartography, chronology, and music theory.The narrative takes the reader from Euler's childhood and education in Basel through his first period in St. Petersburg, 1727-41, where he gained a European reputation by solving the Basel problem and systematically developing analytical mechanics. Invited to Berlin by Frederick II, Euler published his famous Introductio in analysin infinitorum, devised continuum mechanics, and proposed a pulse theory of light. Returning to St. Petersburg in 1766, he created the analytical calculus of variations, developed the most precise lunar theory of the time that supported Newton's dynamics, and published the best-selling Letters to a German Princess--all despite eye problems that ended in near-total blindness. In telling the remarkable story of Euler and how his achievements brought pan-European distinction to the Petersburg and Berlin academies of sciences, the book also demonstrates with new depth and detail the central role of mathematics in the Enlightenment.Some images inside the book are unavailable due to digital copyright restrictions.

Leonor de Aquitania

by Pamela Kaufman

Leonor de Aquitania, la mujer que cambió el destino de las coronas de Francia e Inglaterra. Esta es la historia de Leonor de Aquitania, una de las mujeres más interesantes de la Europa del medioevo. Nacida en 1112, estuvo primero casada durante diez tormentosos años con Luis VII, rey de Francia, un ferviente devoto que la obligó a partir con él a la Segunda Cruzada. La experiencia despertó en la joven deseos de libertad e independencia. Por lo que decidió emplear todas sus influencias para forzar al Papa anular el desgraciado matrimonio con el monarca francés. Leonor intentó entonces casarse con un amor de juventud, pero obligada a desposarse con el rey inglés Enrique II Plantagenet.

Leonor de Habsburgo (Historia Incógnita)

by Yolanda Scheuber

Yolanda Scheuber, utilizando la muy conocida técnica del racconto y recurriendo, asimismo, al narrador en primera persona, logra construir en esta novela la vida de Leonor de Habsburgo, hija de Juana I de Castilla (la Loca) y de Felipe de Austria (el Hermoso). Así, en los últimos instantes de su vida, Leonor empezará a rememorar su historia, cargada sobre todo por el peso de la obediencia. Aun cuando Leonor estuvo destinada a hacer flamear la divisa de los Habsburgo y llegó a ser reina de Portugal y reina de Francia, actualmente existe muy poca bibliografía sobre ella. A pesar de esto, la autora ha conseguido desarrollar una novela histórica sólidamente documentada. Consigue transmitir con gran verosimilitud la vida palaciega, los problemas políticos, las alianzas entre reinos, los intereses desmedidos y las ambiciones descontroladas… propias de aquellos tiempos en los que Carlos V, obligó a su hermana Leonor a anteponer el deber a la felicidad.

La que fuera reina de Castilla representó, para la Europa de la última mitad del siglo XII y la primera del XIII, un nuevo concepto del espacio femenino, heredado de su madre, Leonor de Aquitania, la que fuera reina de Francia y de Inglaterra, y prototipo de mujer universal. En esta Historia Incógnita, Miguel Romero afronta también los pasajes más importantes de la vida política de Alfonso VIII, su esposo, y un breve recorrido por la vida de su madre, personajes sin los que sería imposible entender adecuadamente la vida de la protagonista. Leonor, precursora del desarrollo de la lírica trovadoresca, procedente de la Occitania francesa, abrió la puerta al juglarismo más cortesano y al cultismo popular. Ayudó a potenciar las ideas constructivas del Cister y fue precursora de la aplicación del primer gótico en las catedrales de Sigüenza y Cuenca, promoviendo la construcción de las Huelgas y el Hospital del Rey en Burgos. La fascinante biografía de una mujer fuera de su tiempo que vivió la Castilla reconquistadora del siglo XIII con pasión y con amor.

Leopard 1 Main Battle Tank 1965-95

by Peter Sarson Michael Jerchel

Development of the Leopard 1 can be traced back to November 1956, when the operational requirement for a new battle tank was formulated by the Federal German Armed Forces (Bundeswehr). Originally a Franco-German project, the tank under design was named the 'Standard-Panzer'. The French later dropped out, however, and on 1 October 1963 the 'Standard' tank was officially named 'Leopard', an appropriate choice considering Germany's wartime pedigree with the formidable Tiger and Panther. This book traces the development and service record of the Leopard 1, detailing its control systems, modifications and variants.

Leopard 2 Main Battle Tank 1979-98

by Michael Jerchel Mike Badrocke

In 1963 West Germany and the United States signed an agreement to develop the best tank in the world - the MBT/KPz-70. Though by 1970 this project was stopped, West Germany used the components created for the MBT/KPz-70 to develop a new main battle tank - the Leopard 2. Since 1979, when the first Leopard 2 rolled off the production line, the Leopard 2 has undergone various modifications, and has been exported to various European countries. Enhanced by Osprey's signature colour plates and cutaway artwork, this book examines the development of the Leopard 2 from the first batch to its evolution into the improved Leopard 2 A5, detailing its features and variants.

Leopold Von Ranke: A Biography (Routledge Approaches to History)

by Andreas D Boldt

Leopold von Ranke endeavoured to understand political order within its own historical context. To understand the nature of historical phenomena, such as an institution or an idea, one had to consider its historical development and the changes it underwent over a period of time. Historical epochs, Ranke argued, should not be judged according to predetermined contemporary values or ideas. Rather, they had to be understood on their own terms by empirically establishing history ‘as things really were.’ Ranke’s influence on History as a modern discipline is thus evident, and this is the first volume in English to chart his life and works for a hundred years.

Lepanto 1571: The Madonna's Victory

by Nic Fields

A military historian’s enlightening reassessment of the famous 16th century naval battle between the Ottoman Empire and Pope Pius V’s Holy League.The battle of Lepanto has long been considered one of the decisive naval battles of history. Yet, the savage fighting on October 7th, 1571, left the strategic map unchanged. The defeated Ottoman Turks were able to replace their losses and launch a new fleet the following year. In Lepanto 1571, historian Nic Fields reexamines the battle and concludes that its importance was psychological. It sank the perception of Ottoman dominance and the inevitability of Islam’s westward encroachment beyond the Balkans.With over 200 ships per side, it was the largest naval battle in sixteen centuries and the last major fight between fleets composed entirely of the muscle-driven galley. These slender ships were the direct descendants of the Classical trireme but carried cannon and marines bearing firearms, although massed archery and cold steel still played a major role on the fateful day. Nic Fields gives an excellent account of this fascinating and spectacular battle.
