[Mr Ramsbotham]

He developed theories to explain those facts. Then, he developed experiments to prove whether his theories were correct.

Actually, one develops hypotheses on the basis of observations, then proceeds to the experimentation stage. If experimentation bears out the hypothesis, a theory may be produced. To the average person, the word "theory" implies something that's highly speculative, but to the scientist the word imports something of high probability.

[Congressman Billybob]

Having taken statistics in a PhD program, I know that you are correct. But if I had introduced the word hypothesis, I would have been obligated to spend a sentence or two explaining it to non-statisticians.

Didn't have any sentences to spare. So I wrote it as you see it.
