No degree at all. Ok, Associates in Electronics. Might as well be nothing.
Science is the scientific method.
Observe phenomenon.
Form a hypothesis.
Test hypothesis.
If hypothesis fails, throw out old hypothesis and return to step 2.
If hypothesis is confirmed, pronounce it a theory and if it doesn't work for anyone else, throw it out and return to step 2.
If theory is repeatable, confirmable and consistent, it will eventually be confirmed as a scientific fact.
That's it. That's science. On to the next phenomenon.
