"For a long time I had a strong desire in studying and research in sciences to distinguish some from others, particularly the book [Euclid's] Elements of Geometry which is the origin of all mathematics, and discusses point, line, surface, angle, etc." (Khayyam in Fauvel and Gray, 6.C.2, p. 236)
I don't understand the beginning of the sentence. The author had a strong desire in what exactly ? In studying ? In studying, and research in sciences ? What does he distinguish ? From other what ?
The syntax used confuses me.
