Problem: To Catch a Lion in the Sahara Desert.
- 2 Theoretical Physics Methods
2.1 The Dirac method
We assert that wild lions can ipso facto not be observed in the Sahara desert. Therefore, if there are any lions at all in the desert, they are tame. We leave catching a tame lion as an execise to the reader.
2.2 The Schroedinger method
At every instant there is a non-zero probability of the lion being in the cage. Sit and wait.
2.3 The nuclear physics method
Insert a tame lion into the cage and apply a Majorana exchange operator [6] on it and a wild lion.
As a variant let us assume that we would like to catch (for argument’s sake) a male lion. We insert a tame female lion into the cage and apply the Heisenberg exchange operator [7], exchanging spins.
2.4 A relativistic method
All over the desert we distribute lion bait containing large amounts of the companion star of Sirius. After enough of the bait has been eaten we send a beam of light through the desert. This will curl around the lion so it gets all confused and can be approached without danger.
