Arabic, among many other languages is on a low profile simply because no science is produced in these languages. English won the game because bits and bytes were invented in English. Arabic is indeed a great and very rich language, perhaps more than English, unfortunately, nothing with importance is being produced in Arabic, especially in the last 1.4k years.
I am also unclear what you mean by "especially". Are you saying that there was actually more scientific output in Arabic before 1400 years ago?
