FIBONACCI AND THE GOLDEN RATIO
Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece, to the Italian mathematician Leonardo of Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose, have spent endless hours over this simple ratio and its properties. Biologists, artists, musicians, historians, architects, psychologists and even mystics have pondered and debated the basis of its ubiquity and appeal. In fact, it is probably fair to say that the Golden Ratio has inspired thinkers of all disciplines like no other number in the history of mathematics.
