Modern instruments such as data loggers, pyrometers, accurate scales, etc. made it possible to complete experiments that challenged dearly held beliefs. Our best experiments often resulted in findings that were completely unexpected. Again and again our expectations were confounded by evidence from experiments. It was only because of experimentation that modern designs worked more efficiently. Science to help the planet has become our intention and life's work.
Motivation is more important than training.
Make a difference in a supportive environment. Reinforce the positive results of inquiry. Find something important to do that uses your skills and has very little to do with money, power or influence.
