ø PHI: The Golden Ratio or Golden Section (In Nature, Art, Science and Religion) The Golden Section is a unique Ratio (or relationship between parts) that seems to be preferred by Nature as the best geometry for growth, energy conservation, elegance and has some fundamental relationships to the platonic solids and the Mandelbrot set. It was formally discovered by the Greeks and incorporated into their art and architecture, but it has been shown to occur even in prehistoric art, possibly as a function of Man's natural affinity for it's beauty. The rectangle at left has a vertical edge length of 1 the horizontal or width of the rectangle is 1.618 If we make a line inside and form a square (far left) it creates another 'golden rectangle' (at right)

The Metric System
by Anthony Carpi, Ph.D. hide The metric system , also known as the Système International d'Unités ( SI ), was developed in the late 1700s to standardize units of measurement in Europe. The metric system is the primary system of measurement used through much of the world and in science. Each type of measurement has a base unit to which prefixes are added to indicate multiples of ten. Scientific notation is a shorthand for writing very small and very large numbers.These are practice problems to help bring you to the next level. It will allow you to check and see if you have an understanding of these types of problems. Math works just like anything else, if you want to get good at it, then you need to practice it.
