Fibonacci in nature : The bee ancestry code


Fibonacci numbers also appear in the description of the reproduction of a population of idealized honeybees, according to the following rules:

  • If an egg is laid by an unmated female, it hatches a male or drone bee.
  • If, however, an egg was fertilized by a male, it hatches a female.
Thus, a male bee will always have one parent, and a female bee will have two.

If one traces the ancestry of any male bee (1 bee), he has 1 parent (1 bee), 2 grandparents, 3 great-grandparents, 5 great-great-grandparents, and so on. This sequence of numbers of parents is the Fibonacci sequence.

Between faith and prayer


'Is there anything more important than prayer?' a disciple asked his teacher.
The teacher told the disciple to go to a nearby tree and cut off a branch. The disciple obeyed.
'Is the tree still alive?' asked the teacher.
'As alive as it was before.'
'Then go over there and slice through its roots.'
'If I do that, the tree will die.'
'Prayers are the branches of a tree whose roots are called Faith,' said the teacher. 'Faith can exist without prayer, but prayer cannot exist without faith.'
