User:Entity Valkyrie 2/Heisenburp
A Heisenburp device is an object which can detect the passage of a spaceship without affecting the glider'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.
Examples
The first heisenburp on the left is a glider heisenburp (for the south-west glider in the glider cluster), reacting with a pi-heptomino, the heisenburp device. The glider passes the Pi at T=18. The glider is not affected, but the pi's evolution changed to produce an Eater 1. At gen 18, the glider acts as a rock. The glider's spark causes the Eater 1 to be produced.
Heisenburp devices can be used to not just detect gliders, but also other spaceships such as MWSS, HWSS and Sir Robin. The heisenburp on the right is a combination of an HWSS and glider heisenburps. The heisenburp device of the second heisenburp (right) is a herschel.
- Top left -- Generation 0: The purple HWSS and glider of the spaceship cluster will be used. The HWSS will convert the green herschel to a pi-heptomino (with the help of the blue ship catalyst) shown by the house in cyan, then the glider will change the evolution of the house to make an eater 1 and block (which is the same reaction as the first heisenburp device).
- Left -- Generation 21: The purple HWSS gives out its spark, changing the evolution of the herschel. The image ignores the herschel's first natural glider, which will escape south-westwards.
- Bottom left -- Generation 108: The HWSS cluster glides off to the north undamaged; the purple HWSS didn't receive temporary damage. The blue ship comes into play and will eat the semi-traffic light on the south.
- Top right -- Generation 115: The house (green) has appeared. The purple glider is in the position to be detected. After detection, the house will evolve into the pink eater 1 and block.
- Right -- Generation 130: This is basically the same as T=18 on the first heisenburp. The glider's spark changes the pi-heptomino's evolution.
- Bottom right -- Generation 165: The process is complete. The eater 1 and block have appeared. The purple glider didn't receive temporary damage. The glider cluster drifts off north-eastwards.
