akg4075017 Roger Bacon, OFM (c.?1214 - c.?1292), also known by the scholastic accolade Doctor Mirabilis (Latin for 'wonderful teacher'), was an English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empirical methods.. He is sometimes credited (mainly since the 19th century) as one of the earliest European advocates of the modern scientific method inspired by Aristotle and by later scholars such as the Arab scientist Alhazen. His linguistic work has been heralded for its early exposition of a universal grammar. Pictures From History Pictures From History.

akg3877911 The Wujing Zongyao, (literally: 'Collection of the Most Important Military Techniques') is a Chinese military compendium written in 1044 CE, during the Northern Song Dynasty.. Its authors were the prominent scholars Zeng Gongliang, Ding Du and Yang Weide, whose writing influenced many later Chinese military writers. The book covered a wide range of subjects, everything from naval warships to different types of catapults.. Although the English philosopher and friar Roger Bacon was the first Westerner to mention the sole ingredients of gunpowder in 1267 (i.e. strictly saltpetre, sulphur, and charcoal) when referring to firecrackers in 'various parts of the world', the Wujing Zongyao was the first book in history to record the written formulas for gunpowder solutions containing saltpetre, sulphur, and charcoal, along with many added ingredients.. It also described an early form of the compass (using thermoremanence), and had the oldest illustration of a Chinese Greek Fire flamethrower with a double-acting two-piston cylinder-pump that shot a continuous blast of flame.
