First of all I am a scientist, or a chemist to be more precise. I am changing career to become a chemistry teacher and my course requires me to write an essay on the nature of science and teaching science etc.. I'm having a hard time understanding these 3 philosophers view on what science is? Thomas Kuhn - Came up with the idea of Paradigm shifts and that scientists create their own paradigms to explain a phenomena, this can change hence the term paradigm shift? that's all I understand... Karl Popper - Something about falsifiability? Francis Bacon - no idea. Can anyone explain to me what their view on science was and how they differed to each other as simple as possible? I am trying to critique their views but I first need to understand them in good detail. Many thanks for your assistance.
