The pattern on a sunflower seed is a fibonacci number(34 or so ,I think most probably).
The Fibonacci numbers are one of my favorite numbers.
I know many of them, starting with 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597,2584,4181,6765,10946,17711,28657,46368,…………………………..
Study them, they’re really cool.
