Your reference does not refute my claim. For one thing, a page listing only the "fathers" of fields doesn't speak much to whether the majority of scientists are of the same background.

And even then, your page lists 19 people, 10 of which are clearly not Arab, with one other person of unknown origin. Only 8 of the ones in the list were Arab.

A bigger list is here:

But it would take me too long to categorize each. I did click a bunch, and again - the majority were not Arabs.

Edit: I see my original comment was imprecise. Saying "much of the golden age of science in the Islamic world was not performed by Arabs", does not mean there were no Arabs involved, but that a lot of it was by non-Arabs. However, I wouldn't be surprised if the majority were non-Arabs.
