A few weeks ago I posted a review of the book Science & Islam by Ethan Masood, a tie in with a BBC series from about five years ago. I felt that the book was a bit of a let down, but loved the topic and wanted to read more on it. As a follow up I then wrote a post giving a bit more detail on the Islamic contributions to Mathematics. I wouldn’t pretend that I’m a better writer than Masood, but I wanted to focus a bit more on some of the techniques and details of the work than he did. I do have a scientific background, but I don’t want to make this into a science blog so I’m attempted to strike a bit of an awkward line between the history and the science. With that introduction/disclaimer out of the way – here’s a short summary of the Islamic world’s contribution to Astronomy.
Looking at it now, Mathematics may be the headline grabbing topic for the Islamic golden age but Astronomy (and its unfortunate and misguided relative Astrology) were at least as important. Not only did they provide the motivation for a lot of the work in mathematics and physics, but they also did a lot of very underrated work in moving the topic forward from its ancient roots towards the early heliocentric model of Copernicus. Islamic scholars invented technologies like the astrolabe, published tables of data that later scientists would draw on, and worked out a lot of the mathematical difficulties for the later models. Unfortunately, the political and educational system in the Islamic world meant that they weren’t fully able to capitalize on this; the wonderful observatories were only ever short term institutions and the whole thing stagnated around the turn of the sixteenth century.
