2. He concerned himself not only with those philosophical questions that had been treated by the Aristotelian Neoplatonists of Alexandria but also with such miscellaneous subjects as astrology, medicine, Indian arithmetic, logogriphs, the manufacture of swords, and cooking. He is known to have written more than 270 works (mostly short treatises), a considerable number of which are extant, some in Latin translations.

 3. "Al-Kindi General Hospital" , one of the biggest medical centres in present day Baghdad was named after his tremendous contributions in medical and pharmaceutical sciences

4.In geometry al-Kindi wrote, among other works, on the theory of parallels. He gave a lemma investigating the possibility of exhibiting pairs of lines in the plane which are simultaneously non-parallel and non-intersecting. 

5. Al-Kindi wrote many works on arithmetic which included manuscripts on Indian numbers, the harmony of numbers, lines and multiplication with numbers, relative quantities, measuring proportion and time, and numerical procedures and cancellation. He also wrote on space and time, both of which he believed were finite, 'proving' his assertion with a paradox of the infinite.
