Today, I would like to talk about the Ishango boneor rather the first evidence of a calculator in the world. It is the oldest attestation of the practice of arithmetic in human history. The Ishango bones are actually two 2 bones of baboon, 10 to 14 cm longwith several incisions on each faces.

The left column can be divided in 4 groupswith each group possessing 19, 17, 13, and 11 notches. The sum of these being Those are the 4 bonr prime numbers between 10 and This constitutes a quad of prime numbers.

The central column is divided in groups of 8. By an approximate count, one can find in the parenthesis, is the maximum number: The minimal sum is 48while the maximal sum is The sum of these 4 numbers is However, we know iishango it is composed of 6 groups of 20, 6, 18, 6, 20and 8 notches.

The first bone has been subject to a lot of interpretation. At first, it was thought to be just a tally stick with a series of tally marksbut scientists have demonstrated that the groupings of notches on the bone are indicative of a mathematical understanding which goes beyond simple counting.

In fact, many believe that the notches follow a mathematical succession. The notches have been interpreted as a prehistoric calculatoror a lunar calendaror a prehistoric barcode. Jean de Heinzellin was the first to consider the bone as a vestige of interest in the ishahgo of mathematics.

All said, it is amazing to realize that there were mathematicians 20, years ago on the African continent. It is so great to realize that my ancestors, on the shores of Lake Edouard, were actually brilliant scientists playing with prime numbers.


They were a great civilization long before the pharaohs of Egypt. Thus, in reality, the Ishango bone is the oldest table of prime numbers in the world. African mathematicsAlexander Marshackancient mathematicsClaudia ZaslavskyCongolese mathematicsIshango boneJean de Heinzelinpaleo mathematicians.

Having been trained in both Prehistory and Anthropology, the analysis of this find scotches two widely held misapprehensions in one grand sweep: Tish Farrell on October 11, at 5: However in the website that I was using https: CMN Project 1 sevicerenozdemir on September 28, at African leader and Resistant to French Imperialism 2.


Craddle of Ancient Mathematics […]. African Heritage on January 1, at 8: Actually, very few mathematicians looked at it, and the fact that they do not agree should make us suspicious. Olivier Keller has written an article which should temper the enthousiasm: You desire to see higher mathematics?

Then your mind will make you see it, even if it is not there.

Ancient African Mathematics: The Ishango Bone 26,000+ years old?

Week art85 on September 14, at 5: Technology may change drastically over time, but the the only thing that has fundamentally changed about the internet has been the iishango, use and apparatus on which to access it.

Additionally, whenever researchers have come across some kind of medium that has information, if they want it badly enough, they are usually able to figure it out like the Ishanago Bone https: Although I think that this is a outstanding find, the people of Ancient Kemet stated that they come from this area of Africa. La fuerza de la toma de datos.

Sihango blacks possessed mathematics twenty thousand years ago, while at that time whites in Europe and the uk were crawling on their hands and knees eating their own excrement! The evil tragedy is, when whites eventually came in to contact with mathematics they would come to use it to count African slaves as they were boarded on to ships bound for America and Europe. Good job, just stop of the iceberg for any further information, feel free to contact us about any question of your own choice.
