Fractals in Fruit

We bought a pineapple for dinner yesterday and I noticed the individual small fruits that made up the entire pineapple were fractals.  A fractal is a mathematical set that typically displays self-similar patterns.  Fractals can be exactly the same each time they are repeated, or like in my picture, almost the same each time.  These fractals aligned just so that I could see a part of the Fibonacci Sequence.  The Fibonacci Sequence is a series of numbers where each number is the sum of the two previous numbers.  For example, the 5 yellow fractals and the 8 green fractals make up the 13 blue fractals in my picture.  I thought this was fascinating because I never really paid attention to the way fractals make up entire objects and how the Fibonacci Sequence is common in nature.  (~MG1)

Weave of a Rattan Chair

I saw this chair in my house and I noticed that the backrest is a tessellation.

After zooming into the weave pattern I realized that the pattern was made up of triangles and circles. Ideally, all of the triangles should have the same side lengths and angle measures, but this is not true because the width of each rattan strip is not the same. (~LSU2)
