“For it is easy in experimentation to be deceived, and to think one has seen and discovered what we desire to see and discover.” —Luigi Galvani
I’ve starting reading The Ten Most Beautiful Experiments, by George Johnson. The book is ten short chapters describing how early thinkers and scientists figured out some of the basic scientific truths that we take for granted today. Galileo and gravity, Harvey and blood circulation, Newton and the spectrum of visible light, Lavoisier and oxygen, and Galvani and electricity and muscle contraction are the first 5 chapters that I read yesterday.
I’m struck by two themes that are repeated in each of the stories. First, the diligence each of these men needed in working through the discovery methods to “discover” the truth. Sometimes it took years of work to learn something that today seems so basic. Each of them not only had to think through the problem, they had to invent the equipment and the methods of experimentation to test their ideas. Everything was from scratch. The second theme was opposition. Each of them had to overcome the accepted false “knowledge” of their time. Sometimes, the accepted ideas of how things are dated back hundreds of years. Their discoveries of true principles weren’t accepted by those in power because they didn’t conform with the accepted “facts” of the day. The false status quo often had more strength than the newly discovered truth.
We need to be truth seekers, even when it might not be popular. The truth is waiting to be discovered. We just need to be diligent to find it—and also not be blinded by the opinions of so-called experts.
