Lewis Carroll (actual name Charles Dodgson, 1832 - 1898) was one far-out fellow. In addition to
writing the famous tale of "Alice in Wonderland," he was an accomplished mathematician and
logician. As a prank, he invented an elliptical pool table with a mark at one focus and a hole at
the other focus and challenged expert pool players to sink more balls in the holes than he. What
advantage did he have over those who didn't know about reflecting properties of ellipses?
Solution
Lewis Charoll magic table has the advantage that if the balls pass through one focus i.e.
assuming it as black dot. if it goes through the other focus then the ball whereever you hit then
the ball will finally go in the pool dug. This is the reflection property of ellipse which is used by
Lewis caroll in order to win against its opponent
