The eight solutions of Apollonius' problem. The three given circles are shown in black. The eight solution circles are shown as four pairs (blue, magenta, yellow and grey). In each pair, one solution circle encloses the given circles that are excluded by the other solution, and vice versa. For example, the larger blue solution encloses the two larger given circles, but excludes the smallest; the smaller blue solution does the reverse.

Epsilon Near Zero makes for interesting quantum predictions. Metamaterials can have near zero permittivity, making waves move extremely fast. The natural frequency of a time varying epsilon, near zero, gets smeared out, indicating a broad spectrum of quantum produced photons from the vacuum.
