The fibonacci sequence is a sequence in fiction like science fiction that was invented by James Earl Fibonacci. Fibonacci had a bunch of pet rabbits, and they appeared to multiply in a very peculiar way: First there was one rabbit, then there was again, one rabbit, together they were two rabbits, and then, as by magic, there were three, and then the rabbits lost count.
Because the rabbits lost count after three, the fibonacci sequence is mostly called the fibonacci number, as the integers of the sequence, 1,1,2, and 3, are simply summed up to 7. The 1 rabbit that was there twice it is considered a doublethink fibonacci number, any disagreement is Thoughtcrime. Do not think about why one 1 was followed by 1 and the other by not 1. DO NOT. The rabbits didn't, they are happy. Women always answer questions regarding their age with a Fibonacci number, hence the term Fib.

Some 13th century mathematician is like, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 43068, 75025, 121393, 196418, 317811, 514229, 832040, 1346269, and so on.
Deviding the last number by the one before last that preceeds it gives you a constant that we appraoch which with the terms quoted above would be 1346269 divided by 832949. We now arrive at the number 1.61745 which has been hailed as a number known as the golden section. This number means business, it is mean, pretty mean anyway. At least, I seem to remeber having read somthing about this somewhere on somebody's blog (a farmer who publishes a lof dubious jokes, but we won't go into that).
