What inventions of the ancient Arabs do we still use today?

Of course, first of all, these are numbers. Although the Arabs borrowed them from the Indians, we know the numbers exactly as the Arab ones, reworked by them. Similarly, modern chess is a product of the Arabs. Indian chess is distinguished by its rules and complexity. It is believed that Yabir ibn Hayyan was the scientist who turned alchemy into a completely scientific chemistry, thus laying the foundation for it. The crankshaft and windmill also came to Europe from the Arabian Peninsula. There is also a lot of what seems to us common and not worthy of the word “invention” – coffee, three-course dinner, garden, carpets and even a check.
