Transcript Who Was Fibonacci?

Introduction

This project is about a great mathematician that made a
chain of numbers that are called Fibonacci number
chain. In this PowerPoint I will tell you who he was, and
what kind of math he made.

Who Was Fibonacci?
People say he was the greatest
mathematician of the middle ages. He was
born in Pisa (Italy) the city with the leaning
tower of Pisa. Fibonacci’s name is
pronounced (fib-oh-arch-ee). He was born on
c. 1180. He died on c. 1250. His other job
besides a mathematician he was a merchant.
Fibonacci Numbers

Fibonacci numbers are numbers that are added
one after the other. For example:
0,1,1,2,3,5,8,13,21,34,55…….These are only
the first 12 patterns though.
Rabbit Sequence




I can tell you a bit about the Fibonacci rabbit sequence.
N=new pair of bunnies
M=Mature pair of bunnies
The 0 month there was one N. The 1 month the N pair is
now an M and those rabbit’s had a N. The 2 second
month the N pair is M and they had a N pair so now
there is to M’s and one N. This sequence will go on till
the cow’s come home.
Tree Sequence

The tree sequence is when on the first part of the tree
you have the first number of the Fibonacci sequence the
second part there is still one branch it could go on like
this forever. The taller the tree the more Fibonacci
numbers.
Fibonacci in Nature

The Fibonacci sequence is all around us in math, and
science, and of course nature. The Fibonacci sequence
is in elephants because their tusks are curved, and
another animal that uses the Fibonacci sequence is the
big-horned sheep. The Fibonacci sequence is also in
flowers. It is shown in a very cool way. Cosmos have 8
petals and the daises have 13, 21, 34, 55, 89 depending
on the variety.
Pascal’s Triangle

Pascal’s triangle isn't as hard as it looks. To figure out
the number you are working on look at the two numbers
above the one you are trying to figure out. Add them
together and you will get your number.
Some Secrets About Him And
Others.


Leonardo Da Vinci you may think he was just an artist,
but Fibonacci inspired him to be a mathematician.
Fibonacci also inspired Pascal to be a mathematician.
Equiangular Spiral

The equiangular spiral is pretty much the Fibonacci
sequence. Say you were to use grid paper you find two
squares close to the bottom right corner. Those are the
ones that start the sequence. Then you make a two by
two square. And you could keep going on like that
forever.
Conclusion
As you can see Fibonacci numbers are in nature, math,
science you name it. That is why the Fibonacci
sequence is so important.
