Physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries.
Its legacy is tangible, with terms like algebra, algorithm and alkali all being Arabic in origin and at the very heart of modern science – there would be no modern mathematics or physics without algebra, no computers without algorithms and no chemistry without alkalis.
For Baghdad-born Al-Khalili this is also a personal journey and on his travels he uncovers a diverse and outward-looking culture, fascinated by learning and obsessed with science. From the great mathematician Al-Khwarizmi, who did much to establish the mathematical tradition we now know as algebra, to Ibn Sina, a pioneer of early medicine whose Canon of Medicine was still in use as recently as the 19th century, he pieces together a remarkable story of the often-overlooked achievements of the early medieval Islamic scientists.

And since pi = 3.14, 25 pi square inches can also be written as 25 times 3.14, or 78.5 square inches. Note that the radius of a given circle is half the diameter of the circle. So to find the area of a circle with a given diameter, first find the radius of the circle by dividing the diameter by 2.
