Ringing the changes, or 'change ringing' is where a set of bells is rung in every permutation.
So for (minimalist) example if you have three bells, A,B and C, they could be rung in the orders:
A,B,C
B,A,C
B,C,A
C,B,A
C,A,B
A,C,B
In each row, each bell is rung
once and only once; the only difference is their order.
Obviously, the number of permutations is n! (or n factorial), where n is the number of bells. This function grows quickly with increasing n.
I propose that convoys of people, on foot or in vehicles, could amuse themselves on long trips by reordering themselves in such a manner.
Where possible, horns should be sounded.

The Belgian Tourniquet will never feel the same. |

I'd like to see columns of soldiers walking down the road, reordering themselves from column to column,
Towers-of-Hanoi-style, ordered by height or weight. |

[8th] Don't knock it until you have tried it. |

Trying to control a 2 ton lump of bronze that you can't see, whirling at the end of a rather flimsy rope, with any 1/100 second misjudgement clearly audible to a few thousand bystanders, is not for wimps. |
|
| |
// Don't knock it until you have tried it. // |
|
| |
What makes you think we haven't ... ? Raising the bells, trying not to snap the backstay, getting a firm grip on ther sallie ... too much like hard work. |
|
| |
I never thought anything. |
|
| |
Would this help people avoid accidents on long trips ? |
|
| |
Or would it tend to cause them ? |

The audio snippet in the link should be played in the Math Department to announce lunch time. |

Just operating by instinct? Sort of the GW Bush "trust the gut" approach? It seems to be working out for you! |
|
| |
I used to trust my gut but then it turned on me. Turned huge. |
|
| |
//P.S. you missed A,C,B// |
|
| |
Hah. Can't count to 3!.

// I still believe in gut reactions but its rare I am called upon to talk to peoples intestines. // |
|
| |
Hardly surprising, since you oratorial talents seem more suited to your own Lower Rear Orofice ... |
|

/ But I do have some musical talent in that department. / |
