Quadratic are Everywhere, All you have to do is look!
What do you think when you here "Quadratic Equation"?
Most people immediately jump to thoughts of algebra and math formulas, or think of equations that have letters where the numbers should be. Alternately some may think of graphs of parabolas. While these are accurate from a purely mathematical point of view, there are many other places where we can see quadratic equations in action.
Look around and what do you see?
If you do a little searching, and you know what your looking for, you can see quadratic equations in many place in the world around you. Some places may be expected, such as in engineering, but others may come as a surprise.
