My own revelation of the insight of Karl Popper came from second-year tutorials with Colin McClare, a lecturer in Biophysics at King’s College London. I had the temerity to argue with my tutor. He won. He was right.
I began with The Logic of Scientific Discovery, and read it from cover to cover. Conjectures and Refutations came next.
It continues to amaze me that so many people responsible for making decisions on science, funding, and research priorities seem not to have understood that “Hypotheses are nets – he who casts will catch”.
And that the purpose of every experiment is to test an hypothesis.
