300 BC), mathematicians have studied the golden ratio for its frequent appearance in geometry. The golden ratio or golden mean (only one of the ways the number has been called through the ages) has a special significance in Mathematics and the Arts.Įver since Euclid (fl. That number φ is known as the golden number.

If you divide each number of the Fibonacci sequence by its predecessor, you obtain another sequence of numbers that tends to a number. The Fibonacci sequence are the numbers in the following infinite integer sequence:Ġ, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, … and so on. If it branches every month after that at the growing point, we get the picture shown here.Īgain, whether we consider the branching or the growth of new leaves on sneezewort, the sequence gives the n th Fibonacci number. Suppose that when a plant puts out a new shoot, that shoot has to grow two months before it is strong enough to support branching. This is under the unrealistic assumption that the ancestors at each level are otherwise unrelated.Īchillea ptarmica or “sneezewort” is a plant that displays the Fibonacci numbers in the number of growing points that it has.

The number of ancestors at each level, F n, is the number of female ancestors, which is F n-1, plus the number of male ancestors, which is F n-2.

This sequence of numbers of parents is the Fibonacci sequence. Therefore, any male bee has 1 parent (1 bee), 2 grandparents, 3 great-grandparents, 5 great-great-grandparents, and so on. Thus, a male bee always has one parent, and a female bee has two. However, if an egg was fertilised by a male, it hatches a female. The following assumptions are being made that i f an egg is laid by an unmated female, it hatches a male or drone bee. Honeybees and Sneezewort The Bee Ancestry Codeįibonacci numbers also appear in the description of the reproduction of a population of an idealised honeybees. At the end of the 4th month, the original female has produced yet another new pair, while the female born two months ago produces her first pair also, making 5 pairs.Īt the end of the n th month, we see that the number of pairs of rabbits is then equal to the number of new pairs (which is the number of pairs in month n−2), plus the number of pairs alive last month (n−1).At the end of the 3rd month, the original female produces a second pair, making 3 pairs in all in the field.At the end of the 2nd month the female produces a new pair, so now there are now 2 pairs of rabbits in the field.At the end of the 1st month, they mate, but there is still one only 1 pair.The puzzle posed by Fibonacci was the following…įibonacci’s Rabbits How many pairs of rabbits will you obtain after one year? Now, suppose that our rabbits never die and that the female always produces one new pair (one male and one female) every month from the second month on. Rabbits can mate at the age of one month, so that at the end of its second month a female can produce another pair of rabbits. Suppose a newly-born pair of rabbits, one male and one female, are placed in a field. The original problem investigated by Fibonacci in 1202 was about how fast rabbits could breed given ideal circumstances. According to Tobias Dantzig, his father was “a lowly shipping clerk nicknamed ‘Bonaccio’, which, in the idiom of the time, meant a ‘simpleton’.” Which made ‘Fibonacci,’ the ‘son of a simpleton’… This couldn’t have been further from the truth. From sunflowers to sea shells, the same recurrent mathematical pattern can be observed in Nature, again, and again, and again…įibonacci “Leonardo of Pisa” was an Italian mathematician who lived in the Middle Ages. The Fibonacci numbers are applicable to the growth of every living thing: a single cell, a grain of wheat, a hive of bees, all of mankind. From the leaf arrangement in plants, to the pattern of the petals of a flower, the bracts of a pine cone, or the scales of a pineapple.
