Hyperbola

[Sarah]

A curve formed by a section of a cone, when the cutting planemakes a greater angle with the base than the side of the cone makes.It is a plane curve such that the difference of the distances fromany point of it to two fixed points, called foci, is equal to a givendistance. See Focus. If the cutting plane be produced so as to cutthe opposite cone, another curve will be formed, which is also anhyperbola. Both curves are regarded as branches of the samehyperbola. See Illust. of Conic section, and Focus.

some weird shape only math geeks know about.

a double edged curve no one knows about.

Hyperbola: A disease rampant among those who discuss Ebola with little or no scientific knowledge and thereby are prone to making outrageous, stupid and simplistic suggestions on how to deal with the complex issues surrounding epidemiology and biology.
Symptoms include keeping children home from school because someone three towns away might POSSIBLY been in the same country as a confirmed case, amnesia for certain public officials who voted to drastically cut medical research and development budgets and now need to cover their ass, and/or being a commentator on Fox News.

[Julian]

A symmetrical open curve formed by the intersection of a circular cone with a plane at a smaller angle with its axis than the side of the cone.
