It’s #FibonacciDay in the US, because when the date is written MM/DD, it forms the beginning of the #Fibonacci sequence: 1,1,2,3. The pattern is found throughout nature in pinecones, flowers, spiral shells, etc. Celebrating the day reminds me of Rader’s love for math concepts. pic.twitter.com/xp64hTI7xS
