As Arabs were travelers and tradesmen they carried their ideas, inventions and enormous amounts of freights to where ever they travelled to. They got the idea from India, China, Ancient Egypt etc. Some say the knowledge gap was occurred due to deliberate conspiracies. This was mainly because they never wanted their offspring to know what Muslims have contributed to their advancement and just wanted to show the European superiority. After the industrialization, secularization started to exist in Europe. After these events Muslim inventions were rare. Europe wanted to strip itself of their past dark ages from the history and also wanted to rise fresh. With roughly 1.6 billion Muslim in the world today, only two have won Nobel Prize in science.
