This remarkable curve appears in many places in nature and in many objects made by humans. It is the shape made by water streaming out of a drinking fountain, as well as the shape of the cable on a suspension bridge. When you stir a glass of water, the surface of the water forms a concave shape called a paraboloid, which is a three-dimensional version of a parabola. Telescope mirrors, satellite dishes, and reflectors on supersensitive microphones all take the form of paraboloids, because they are able to reflect waves coming from far away to a single point, called the focus.
Minute by minute, day by day, they go up and down. Can you learn something about the stock market by thinking of stock prices as random walks? On this graph, one line shows actual stock prices, and the other represents a random walk. Can you tell which is which?
50 ❂ Cutting a Cone What does a parabola have in common with a circle and an ellipse? All three of these curves can be made by cutting a cone in different ways, called conic sections. If you cut a cone horizontally at its tip, you will see a surface in the shape of a circle. Likewise, if you cut it slantwise at its tip, you will reveal an ellipse. Furthermore, if you cut it at an even steeper slant across the cone— at the same angle as the side of WORDS + + KNOW the cone—you will produce a parabola.
