Leonardo of Pisa (Fibonacci) · Mathematics
The real mathematics linking the Fibonacci sequence to the golden ratio - the ratio of consecutive terms converging on phi (about 1.618) - done honestly, together with a clear-eyed debunking of the exaggerated ‘golden ratio in everything’ mysticism, most of which has nothing to do with Fibonacci at all.
You learned that the ratio of consecutive Fibonacci numbers converges to the golden ratio phi (about 1.618), the positive solution of x squared = x + 1; that Euclid had defined this same ratio as dividing a line in ‘extreme and mean ratio’; and that Fibonacci himself never linked his sequence to it. Explai…
Leads to Euclid.
