Question - 199

The second visual shows a common motivating example of the work of the man in the first visual. The third visual is an obscure but quite innovative use of the same work. Identify the man and the work he is most famous for.

Answer: The man is Leonardo of Pisa, more popularly known as Fibonacci. The second visual shows how a rabbit population evolves according to the Fibonacci sequence if, as Rahul Trivedi put it, they are left to do what they do best. The third is an abacus-like device used by Incans called the Yupana which is based on the Sequence. Rajeev, Rahul Trivedi, An0n, Raghu, Schmetterling, Hirak, Adi, Rajesh, Avinash, Shweta and Swapnaa got this. Well done.

Fibonacci and his series.

Leonardo of Pisa who popularized the Indian number system in the west using an old Indian problem.

Better known as Fibonacci.

BTW, the rabbit population diagram looks like a proof of Mendel's experiment. Genetic features being inherited and some mutations on the way :)

Oh, forgot about the third thing. It is a counting tool used by the Incas, which takes advantage of the fact that the Fibonaaci numbers provide the continued fraction approximations of the golden ration (Well, the calculator was not based on this fact, but it sounds cool anyways)

Fibonacci and the eponymous sequence

That Fibonacci and his rabbits. The last one is a Yupana, an incan abacus which is believed to have worked using the fibonacci series.

Fibonacci

Liber Abaci book written by Fibonacci considered the problem of how many pairs of rabbits would there be each month if you started with a pair of newborn rabbits to explain a number sequence now known to us as Fibonacci series

yupana.....counting tool used by Incas based on Fibonacci numbers

Fibonacci (didn't know his name was Leonardo of Pisa and that he's nicknamed Fibonacci coz he's the son of Bonaccio).

He's famous not for inventing the F-series, but for writing the book "Liber Abaci" which introduced the Hindu-Arabic numeral system to Europe and in which the F-series was used.
