Fibonacci Sequence in Nature

In this video, Caitlin introduces the Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones. The sequence, named after Italian mathematician Fibonacci, is explored through its historical context and mathematical properties. Caitlin demonstrates how to visualize the sequence by drawing a spiral using boxes with side lengths corresponding to Fibonacci numbers. The video also highlights the occurrence of Fibonacci patterns in nature, such as in leaves, flowers, and shells. The episode concludes with safety tips for exploring nature and encourages viewers to observe these patterns themselves.

Who was Fibonacci and what is he known for?
