Indeed. In fact, it is one of the most amusing aspect of the anglophone west (at least for the last few decades). Despite public perception (by public I mean those who have been to university since the 90s), Western historians of science and mathematics in general have never not acknowledged the previous works of the Persianate civilizations commensurate to their knowledge of them in their time. But somehow in the last few decades professional historians have had to waste time figuratively looking over their shoulders lest they be percieved as being Eurocentric. And, if they were to somehow find a way to show -- requiring whatever hermeneutical gymnastics -- that a prominent scientist was influenced (or even better, had stolen) from some other "cultures" than nothing better! (ex: Copernicus from the Maragha school as an example of interpretive gymnastics)
But, of course, this is one of the symptoms of the degeneration that now afflicts your particular civilization and is bringing about it's inevitable transformation to something else -- but better this than the fate of the Abassids or the Sung.
I'm going to get downvoted to oblivion for this. But it's still the truth: just wait until you try to get muslims to confirm what exactly about islam "safeguarded" science in the middle ages.
The answer is slavery, and patronage by very, very rich people (who outright owned the scientists, and these in turn kept libraries of the great scientific works of the past, as trophies for the sultan, with zero public access). Oh and the fact that they recreated the Roman habit of kidnapping slaves and then selling them, sometimes an enormous distance from where they were captured. That is how Hindu numerals spread.
One very famous example is the "Blue Mosque", the greatest piece of islamic architecture for over 500 years, the tallest building in the world for a very long time (only overshadowed by the Church it was copied from: the Aya Sofia) which is a copy of a Church building by a Jewish architect (who was a slave to the sultan). Yes, minarets are a Christian idea.
Perhaps this is the reason the Blue Mosque doesn't have one of the defining features of islamic architecture of mosques: it doesn't have a catwalk, a podium for selling slaves, which most ottoman mosques have.
Then, usually during periods of economic stress, muslims destroyed their science, usually for religious reasons. Of course, this happened in the Christian west too. In the west science (specifically the copying of books by the Catholic church, then giving public access to them. No public access existed in any caliphate) recovered faster than these religious attacks could destroy it. In islamic nations it didn't. Islam was more scientifically advanced in 800 than in 1800 (or 1900). Or, to put it another way: the more actual muslims a society had (in 800 that was almost none), the less science existed.
Why? The only disagreement with these claims comes from islamic supremacists. Even in islamic sources directly you can verify most of the claims (slavery, Blue Mosque - Aya Sofia + architect, slavery in mosques, barely any muslims in early muslim society ...)
Look up on Wikipedia, look up in history books. These are not small details.
