The central part of some flowers displays an interesting mathematical pattern: interlocked clockwise and counter-clockwise spirals. The numbers of clockwise or counter-clockwise spirals, called parastichy numbers, tend to be two consecutive numbers in the Fibonacci sequence (where each number is the sum of the two previous numbers in the sequence). . . . . . . . . . . #math #science #flower #nature #naturephotography #plant #plantlife #life #beauty #earth #center #pattern #naturepattern #sum #fibonaccisequence #number #spiral #mathematical #macro #macrophotography
