If it doesn't work, it's Physics. If it's incomprehensible, it's Mathematics. The difference between the laws of nature and Murphy's law is that with the laws of nature you can count on things screwing up the same way each time. If an experiment works, something has gone wrong. Experiments should be reproducible, they should all fail in the same way.
Exceptions always outnumber the rules.
Don't believe in miracles, rely on them. If the facts do not conform with the theory, they must be disposed of. If enough data is collected, anything may be proven by statistical methods. When in doubt make it sound convincing. First draw your graphs, then plot your points.
