Narrow Escape
The Narrow escape problem is a ubiquitous problem in biology, biophysics and cellular biology which has the following formulation: a Brownian particle (ion, molecule, or protein) is confined to a bounded domain (a compartment or a cell) by a reflecting boundary, except for a small window through which it can escape. The narrow escape problem is that of calculating the mean escape time. This time diverges as the window shrinks, thus rendering the calculation a singular perturbation problem.

“Comedy is an escape, not from truth but from despair; a narrow escape into faith.”

“His virtues walked their narrow round,

The single talent well employed.”

“Narcotics have been systematically scapegoated and demonized. The idea that anyone can use drugs and escape a horrible fate is an anathema to these idiots. I predict that in the near future, right wingers will use drug hysteria as a pretext to set up an international police apparatus.”
