欧洲世界于1182年“重新发现”磁罗盘用于海上使用。尽管欧洲人声称这项发明,但它最初是由中国人在公元200年左右使用的,主要用于算命。中国人在11世纪用磁罗盘进行海上旅行。带扣眼的功能按钮用于固定或关闭衣服,这些按钮于13世纪首次出现在德国。在此之前,按钮是装饰性的而不是功能性的。随着13世纪和14世纪欧洲紧身服装的兴起,纽扣变得普遍。使用按钮作为装饰或装饰的历史可以追溯到公元前2800年左右的印度河流域文明,大约在公元前2000年左右。和古罗马文明。意大利数学家莱昂纳多斐波那契主要通过他在1202年的Liber Abaci(也被称为“计算之书”)中的成分向西方世界介绍了印度 – 阿拉伯语编号系统。他还向欧洲介绍了斐波纳契数列。英国科学家,哲学家和方济各会修士Roger Bacon是第一个详细描述制造火药过程的欧洲人。他的书中的段落,“Opus Majus”和“Opus Tertium”通常被认为是欧洲对含有火药基本成分的混合物的首次描述。人们认为,培根最有可能目睹了至少一次中国鞭炮的示威活动,这可能是在此期间访问蒙古帝国的方济各会获得的。在他的其他想法中,他提出了飞行机器和机动船和马车。

The European world “rediscovered” the magnetic compass for use at sea in 1182. Although the Europeans claimed the invention, it was originally used by the Chinese in around AD 200 and was mainly used for fortune telling. The Chinese used the magnetic compass to travel at sea in the 11th century. Buttons with buttonholes are used to secure or close clothes, which first appeared in Germany in the 13th century. Prior to this, the buttons were decorative rather than functional. With the rise of European tight clothing in the 13th and 14th centuries, buttons became commonplace. The history of using buttons as decorations or decorations dates back to the Indus Valley civilization around 2800 BC, around 2000 BC. And ancient Roman civilization. The Italian mathematician Leonardo Fibonacci introduced the Indian-Arabic numbering system to the Western world mainly through his composition in Liber Abaci (also known as the “book of computing”) in 1202. He also introduced the Fibonacci sequence to Europe. British scientist, philosopher and Franciscan monk Roger Bacon was the first European to describe in detail the process of making gunpowder. The passages in his book, “Opus Majus” and “Opus Tertium”, are generally considered to be the first description of a mixture of essential ingredients in gunpowder in Europe. It is believed that Bacon is most likely to have witnessed at least one demonstration of Chinese firecrackers, which may have been obtained by the Franciscans who visited the Mongol Empire during this period. Among his other ideas, he proposed flying machines and motor boats and horse-drawn carriages.
