Somali Fox and Calculus Options
Posted: Fri Jan 11, 2008 5:06 pm
Abstract: we look into a Somali legend, in which wild animals
share a prey. A fox distributes in a way that the lion
receives the whole. It involves infinitesimal calculus.
The fox in the somali short stories is always cunny and opportunist.
In this note, we shall show how it does this with math. Here is the story.
The family of wild animals (habar dugaag) once killed a she-camel as a prey.
The lion in this sequel referred to as the king) ordered the "caalle"
(waraabe ?) to distribute the meat in a fair way. The latter announced:
" One half for the lion and the remaining half for the rest of us." The king
punished him and then chose the fox to do the work. The fox declared:
" One half of the camel meat for the king. From the remaining, again one half
for the king and so on." [ Hasha ma bar oo bar, bar indhaweyne libaax.
Badhka haray ma fallar oo fallar, falladh indha weyne libaax ...]
The lion: " When did you learn this fairness and justice."
The fox: " When I saw the injured eye of CAALLE."
[" Dawoy yaa ku baray garniqidaa." " Isha caalle oo gebi ka lulata."]
It is not readily evident that the lion gets the whole camel. But when we
add up his share, we get the following geometric series:
1/2 + 1/4 + 1/8 + 1/16 + ...
A well known fact in elementary analysis (calculus) shows that the series
converges to one (which is the whole camel).
