Eating the Parabola Cookie
The parabola (from the Greek: παραβολή) is a conic section generated by the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface.
A parabola can also be defined as a locus of points which are equidistant from a given point (the focus) and a given line (the directrix).
A particular case arises when the plane is tangent to the conical surface. In that case the intersection is a degenerate parabola consisting of a straight line.
ORIGIN Latin, from Greek parabole ‘placing side by side’.

There seems to be an incomprehensible number of cars parked in the butterfly conservatory parking lot...the culture must be different in that section of the triangle. When you turn your head to the right, it's not unusual to see a small plane or even hear the buzzwhirr of a helicopter...
