A lament: When I have entered into discussions about the greenhouse effect, global warming, climate change, I have been routinely criticized as not understanding science and/or its method by those on both sides of the controversies. And John O’Sullivan, editor of PSI, has recently shared with me: “As you correctly identify, the main complaint I get about your articles is that they seem rambling and confusing. Best to keep to simple points and remember that most readers have shorter attention spans. Few are retired with time on their hands and prefer to come here to get neat ‘packets’ of information.” 
I conclude these critics might not be familiar with the science of chemistry, and if they once were, maybe they have forgotten. I have this forgetting problem all the time. But I consider this is not the entire answer because I know as a chemist I was not the scientist I am today. For near the end of my career as a chemistry instructor at a small community college I began to read the classic books written by the founders of what I term—modern science. These authors were Galileo Galilei and Isaac Newton.
