 | | In the real-life, macroscopic world of people, elves and flying reindeer, the quantum behaviour of each of the squillions of particles from which we are made averages out, so what we see is the everyday phenomenon of causes preceding effects, and people who can never be in two places at once. |
 | | Cynics might attribute this last consequence to the deficiencies of Railtrack, but it is a fact that real people, even bearded men with red hats and big boots, tend to be found in discrete locations, irrespective of whether they are being watched or not. |
 | | Importantly, these macroscopic quantum objects observe the rules of the quantum world when cooled to within a whisker of absolute zero - minus 273 C. Any warmer than this, and the choreography breaks down and the clusters behave like any old bunch of atoms. |
