Anthony's Law of Force

Barber's Laws of Backpacking
1. The integral of the gravitational potential taken around any loop
train you choose to hike always comes out positive.
2. Any stone in your boot always migrates against the pressure
gradient to exactly the point of most pressure.
3. The weight of your pack increases in direct proportion to the
amount of food you consume from it. If you run out of food, the
pack weight goes on increasing anyway.
4. The number of stones in your boot is directly proportional to the
number of hours you have been on the trail.
5. The difficulty of finding any given trail marker is directly
proportional to the importance of the consequences of failing to
find it.
6. The size of each of the stones in your boot is directly propor-
tional to the number of hours you have been on the trail.
7. The remaining distance to your chosen campsite remains constant as
twilight approaches.
8. The net weight of your boots is proportional to the cube of the
number of hours you have been on the trail.
9. When you arrive at your chosen campsite, it is full.
10. If you take your boots off, you'll never get them back on again.
11. The local density of mosquitoes is inversely proportional to your
remaining repellent.

Finagle's Rules
Ever since the first scientific experiment, man has been plagued by the
increasing antagonism of nature. It seems only right that nature should
be logical and neat, but experience has shown that this is not the case.
A further series of rules has been formulated, designed to help man accept
the pigheadedness of nature.
Rule 1 To study a subject best, understand it thoroughly before you
start.
Rule 2 Always keep a record of data. It indicates that you've been
working.
Rule 3 Always draw your curves, then plot the reading.
Rule 4 In case of doubt, make it sound convincing.
Rule 5 Experiments should be reproducible. They should all fail in
the same way.
Rule 6 Do not believe in miracles. Rely on them.

pleases.

1 Computers are unreliable, but humans are even more unreliable.

2 Any system which depends on human reliability is unreliable.
3 The only difference between the fool and the criminal who attacks a
system, is that the fool attacks unpredictable and on a broader
front.
4 Undetectable errors are infinite in variety, in contrast to dectable
errors, which by definition are limited.
5 Investment in reliability will increase until it exceeds the
probable cost of errors, or until someone insists on getting some
work done.
