The origins of western science
By Howard Jones
In 2002, in her book Ornament of the World, Maria Rosa Menocal gave us an insight into the debt we owe the Islamic civilization of al-Andalus, which from 750 to 1492 did so much to shape the western culture of the post-Renaissance. We tend to think of western science as essentially beginning with Copernicus, with a nod in the direction of some of the ancient Greek philosophers, such as Aristarchus for the heliocentric theory; or Leucippus and Democritus for the atomic theory. Bertrand Russell portrayed the Islamic scholars as doing little other than transcribe the scientific philosophy of ancient Greece. Menocal showed us how Christian, Jewish and Islamic scholars worked together in harmony not only to render ancient Greek ideas into Arabic, Hebrew and Latin, but also to create much that was new. Al-Khalili adds to this source of original knowledge.
Jim al-Khalili presents another side of this story, but his book focuses on the 9th century Abbasid caliphate of Abu Ja'far Abdullah al-Ma'mum that was centred on Baghdad. It was called Bayt al-Hikma, the House of Wisdom. Jim al-Khalili is Professor of Theoretical Physics at the University of Surry and has already written one of the more accessible books on quantum physics. There were scholars in Baghdad in many of the scientific disciplines. The names of some of these have emerged in the west over recent decades, like al-Khwarizmi whose book, the title of which is abbreviated to al-Jebr, gave us our algebra; al-Biruni, who was a contemporary of Ibn Sina (Avicenna) and debated the philosophy of science with him. Our word `alchemy' is from the Arabic `al-kimiya', `the art of transmutation'; and there are many other words in everyday use, such as alkali and algorithm, that have an Arabic origin.
Most of the other scholars whose work al-Khalili describes were quite new to me. There is something of the general history of the period in this book; but for the most part it focuses on cosmology, arithmetic, algebra, physics, philosophy and medicine in separate chapters, and the contribution of the Arabian scholars. We must remember that this is only two centuries after the life of The Prophet and the social system that his vision inaugurated. So the progress made in learning was considerable and rapid. Of course, the Islamic scholars were also busy translating Greek and Roman texts, but this book puts into perspective the derivative work with the original.
This is a fascinating book, full of scholarship and original historical material, and absolutely no symbolic mathematics to deter the reader. It puts the ancient scholars of Baghdad and their contribution to our heritage into a very human context, though perhaps we could have done with less personal material. There are several pages of Notes, a Glossary of scientists, and an Index at the end. This would make an excellent complement to the books by Menocal and that on the history of western ideas by Richard Tarnas.
