Euclidean Geometry • Triangles • Circles • Squares • Rectangles • Trapezoids • Pentagons • Hexagons • Octagons • Cyclinders
Try drawing nature using Euclidean Geometry: • A tree using cylinders??? • A mountain range using triangles and pyramids??? • Clouds using circles??? • Leaves??? • Rocks??? • Humans and animals with rectangles and circles???
The point is this… • Our world is fashioned with rough edges and non-uniform shapes. • Euclidean geometry describes ideal shapes which rarely occur in nature. • Why then do we even bother with Euclidean geometry?
Plato believed he could explain nature with five regular solid forms. Astronomers believed that our orbit around the sun was circular. Scientists now know that Plato’s shapes are particles and waves. Astronomers now know that our orbit is elliptical not circular. 1. Historically…
2. The mathematics is relatively easy. • Perimeter • Area • Surface area • Volume • Relationships between two shapes For example: Square vs. shape of Mississippi
3. Men and women consider a house with smooth edges and uniform shapes more beautiful than a house with rough edges and non-uniform shapes. • Why is that nature is more beautiful with rough edges and non-uniform shapes and man made objects are less beautiful with rough edges and non-uniform shapes? And vice versa?
Fractals Defined. • Geometry of irregular shapes which are characterized by infinite detail, infinite length, and the absence of smoothness. • Let’s first see what a fractal is not.
A rectangle is not a fractal. • When we look through a microscope at the rectangle do we see any new details.
