Few biographies of al-Biruni exist in English, and this is the first for young adults. Al-Biruni studied medicine, physics, philosophy, mathematics, and astronomy, and possessed a profoundly stunning intellect. He helped develop mathematics, from trigonometry to calculus, mapped cities and the distances between them, and inspired others in the virtuous pursuit of knowledge.
There aren't many books available in English about the great scientists of the islamic world, so the publication of this series about Al-Biruni, Al-Khwarismi, Ibn-Sina etc is very welcome. A bit boring and summarizing style with an apologetic tendency. By the way, it is just 100 pages with big letters, and has nice illustrations.
