Coats of arms were at first used only by kings and princes, then by their great nobles, but by the mid-13th century arms were being used extensively by the lesser nobility, knights and those who later came to be styled gentlemen. In some countries the use of arms spread even to merchants, townspeople and the peasantry. From the mundane to the fantastic, from simple geometric patterns to elaborate mythological beasts, this fascinating work by Terence Wise explores the origins and appearance of medieval heraldic devices in an engagingly readable style accompanied by numerous illustrations including eight full page colour plates by Richard Hook.

After disastrous defeats at the hands of the Mongols in the 13th century, the Russian principalities became vassals of the Khans of the Golden Horde for more then 200 years; and at the same time the western princes faced the German crusaders of the Teutonic Order. Remarkably, Russia responded with a new surge of military vigour. Eventually, freedom from the 'Mongol yoke' coincided with a degree of unity around a powerful new state - Muscovy. This exciting chapter of history is illustrated with rare early paintings, photos, diagrams, and eight plates reconstructing the mixed influences of East and West in the appearance of Russian warriors.

In 1543 three Portuguese merchants entered a turbulent Japan, bringing with them the first firearms the Japanese had ever seen: simple matchlock muskets called arquebuses. They proved a decisive addition to the Japanese armoury, as for centuries the samurai had fought only with bow, sword and spear. In 1575, one of the greatest original thinkers in the history of samurai, Oda Nobunaga, arranged his arquebusiers in ranks three deep behind a palisade and proceeded, quite literally, to blow his opponent’s cavalry to pieces, marking the beginning of a new era in Japanese military history.

In the first half of the 18th century the French had been the European leaders in artillery, possessing the only standardised range of pieces. These pieces, were sturdy but extremely heavy. This books shows how at the beginning of the Seven Years' War, Austria seized the lead by introducing new light field pieces - the 3pdr., 6pdr., and 12pdr. guns - and some excellent light howitzers. Other powers adopted this new system, however no complete overarching methodology existed until the implementation of the Gribeauval system, which was to revolutionise the artillery of Europe and make possible the highly efficient field artillery of the Napoleonic Wars.

Over the past three years PHP has evolved from being a niche language used to add dynamic functionality to small sites to a powerful tool making strong inroads into large-scale, business-critical Web systems.
The rapid maturation of PHP has created a skeptical population of users from more traditional "enterprise" languages who question the readiness and ability of PHP to scale, as well as a large population of PHP developers without formal computer science backgrounds who have learned through the hands-on experimentation while developing small and midsize applications in PHP.
While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on "scaling" PHP for large-scale, business-critical systems. Schlossnagle's Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

Эта книга является непосредственным продолжением книги «Элементы комбинаторной и дифференциальной топологии». Она начинается с определения симплициальных гомологий и когомологий; приводятся многочисленные примеры их вычисления и их приложений. Затем обсуждается умножение Колмогорова-Александера на когомологиях. Значительная часть книги посвящена различным приложениям (симплициальных) гомологий и когомологий. Многие из них связаны с теорией препятствий. Одним из таких примеров служат характеристические классы векторных расслоений. Сингулярные гомологии и когомологии определяются во второй половине книги. Затем рассматривается ещё один подход к построению теории когомологий — когомологии Чеха и тесно связанные с ними когомологии де Рама. Книга завершается различными приложениями теории гомологий в топологии многообразий. В книге приведено много задач (с решениями) и упражнений для самостоятельного решения.
Для студентов старших курсов и аспирантов математических и физических специальностей; для научных работников.
