Please help me before my time runs out. Read the passage from Sugar Changed the World.
The vast Muslim world was wonderful for the growth of knowledge. The Greeks had developed a level of practical experience and technical understanding a thousand years more advanced than anyone else nearby. The Muslims began to translate some of these ancient Greek texts. From India, Muslims learned of the zero, which allowed them to invent what we still call "Arabic” numerals. And because the Koran, the sacred book of Islam, is written in Arabic, scholars throughout the Muslim world learned to read Arabic and to share their knowledge. The Muslims swept past Jundi Shapur and learned the secrets of sugar. As they conquered lands around the Mediterranean Sea, they spread word of how to grow, mill, and refine the sweet reed.
