We can dance if we want to
We can leave your friends behind
'Cause your friends don't dance
And if they don't dance
Well they're no friends of mine.
I say, we can go where we want to
A place where they will never find
And we can act like we come from out of this world
Leave the real one far behind
And we can dance.
Although not any of Hipatia works remains, it is known that she was an exceptional astronomer, well-known for the mathematical study of conical curves. One thousand, two hundred years later, in the 17-th century, astronomer Johannes Kepler described that one of those curves, the ellipse, governs the movement of the planets.
