Now, no relation to Kevin Bacon, so if you're playing six, seven degrees, six degrees of separation, you can't use Francis Sir Bacon. But nevertheless, Francis Sir Francis Bacon is really the guy who invented or came up with the scientific method. So the scientific method, I know you know from all of your science classes, starts with kind of stating a problem, gathering facts, developing a hypothesis, and then testing that hypothesis and observing the results, and then doing it over and over again. And so you can come up with truth in the science, with science, with the natural world. So this is really different from the way that things were done before the 1600s. This is right around 1600. In the Middle Ages, in the Dark Ages, in the 1300s, 1400s, really truth is set by the Catholic Church.
