Heisenburp
A Heisenburp device is a pattern which can detect the passage of a spaceship without affecting the spaceship's path or timing. The name is a reference to Werner Heisenberg's Uncertainty Principle, a principle in quantum physics which states that it is physically impossible to detect a particle without affecting it in some way; it was coined by Bill Gosper. The first Heisenburp device was constructed by David Bell in December 1992.
Some Heisenburp reactions do affect the spaceship, but only for a few generations, after which it evolves as if it had never been affected. Such reactions have generally been called "pseudo-Heisenburp" reactions since the discovery of "pure" or "true" Heisenburp reactions where the spaceship is not even temporarily affected.
Example
Natural Heisenburp is a periodic Heisenburp device found by Brice Due on January 3, 2007.[1] A glider passes through the following p46 twin bees shuttle pair completely unaffected, but a second glider (out of the blue) emerges soon, following the first at a 2hd offset.
