Math CentralQuandaries & Queries


I have a research paper due on real life uses of conic sections
I've looked through all your conic topics and uses of them,
but and i cant seem to find real life uses for circles.
What are real life uses of circles?


How about the wheels on a bicycle or the wheels on a car? How does the odometer in a car know how far the car has travelled? Does it use the circumference of the circular tire?

The information on the hard drive on your computer or on a DC or DVD is stored in concentric circles.

Why do above ground pools have a circular shape?

All of trigonometry is based on the circle. In fact many books call the section on trigonometry Circular Functions.

These are a few ideas.
