Eureka! - I have found it!

It was a flash of eureka.

Eureka! We have found it -- a pristine reef, where corals are alive and healthy and form a forest so thick that there is no space even for sand between them.

The shortest distance between two points is a straight line.

Give me where to stand, and I will move the earth.

Give me a lever long enough, and a prop strong enough, I can single-handed move the world.
