You'd be surprised by how much of today's used mathematics is actually "old". I mean most of it (even the mathematics of electromagnetism) hasn't changed since the 19th century and before, we are using the same theorems they used at the time.
Maxwell-Faraday equation.
Maxwell-Gauss equation.
Maxwell-flux equation.
Maxwell-Ampère equation.
However the point that medieval gives the false impression that Al-Kāshī was a European astronomer still stands but unlike what you suggested before; changing the title, I hope this changed the impression.
I was suggesting that the use of the term may not have been accurate given the fact Iran was different from Europe.
Nonetheless, Al-Kāshī(1380-1429) lived under Timurid dynasty (1370–1507)[0] succeeding Iran's "Middle Ages" making him thus, not an "Iranian medieval" astronomer.

"The Middle Ages was a period in Western history spanning the time from the 5th to the 16th century"[0]
and
"Middle Ages, the European historical period from the 5th to the 15th century (476-1453). By analogy, the term is also used to refer to periods in nations outside of Europe having similarities in social and military development"[0]
Iran, even during that period of Islamic rule , is far from similar to Europe on both the social and military level.
If either of us is to tolerate a certain degree of imprecision (for me that medieval concerns not only Europe and for you that the Islamic Golden Age is not a fixed time interval) then we'll come to a understanding, other than that, I think there is not a proper name of that period.
Edit: Note that the goal is to convey the time period, not the geographical location. When it comes to history those two are inter-dependent you cannot make a random choice of words.
Al-Kāshī was not a "medieval astronomer", the Middle Ages are related to European history and Al-Kāshī lived in Iran during the Islamic Golden Age.
100km is the altitude where lies the Karman Line[0]; the boundary between the Earth's atmosphere and outer space. So technically, space IS what's above 100km ;)
Here's another great one: a certain well known mathematican, we'll call him Professor P.T. (these are not his initials...), upon his arrival at Harvard University, was scheduled to teach Math 1a (the first semester of freshman calculus.)
He asked his fellow faculty members what he was supposed to teach in this course, and they told him: limits, continuity, differentiability, and a little bit of indefinite integration.
The next day he came back and asked, "What am I supposed to cover in the second lecture?""
Of course it does, it is about square roots and inversions.
In most of the cases, in order to optimize an algorithm or solve a problem, mathematics will do it for you, and that ranges from simple arithmetic properties to base changing theorems in linear algebra.
You just can not tackle such subjects without expecting it to contain a fair bit of math .
