This treatise is a collection of musings on the properties of elliptical parabolas. A parabola, you ask, is it a circle? No, no. A parabola is a curve that opens upwards, like a smiley face. But not just any smiley face, mind you. A parabola is like a smiley face with a hint of existential dread.
No, really, they're not circles.

But wait, there's more! Visit our Parabolas in Space page to learn about the parabolas that exist beyond this mortal coil.
Or, if you will, the Euclid's Dilemma page, where we ponder the implications of Euclid's work on our modern understanding of elliptical parabolas.
