Gabriel’s Horn is a three dimensional surface that contains a finite volume but has an infinite surface area. It is made by taking the two dimensional graph of y=1/x and revolving it around the x-axis (with the domain of x ≥ 1). If we look at x coordinates from 1 to a, the volume can be…

14-billion-years-later:

Kirlain photography is a method of photographing the electrical discharge of various objects, the process involves placing said object upon a photographic plate and running a voltage across it. This outlines the subject, in this case a set of leaves, with a corona of electrical energy that is only visible on the plate.
