I am doing my problem-based-learning (PBL) background research and this picture popped into my head.
This diagram represents how we view knowledge and applies to any field of subject, not just medicine. As you study any subject more in-depth, you soon realize that you don’t know anything at all. As your knowledge increases, so does your awareness of what you don’t know. I can easily see how a person can devote their entire lives to learning about the kidneys, the brain or even an obscure protein. The knowledge never stops growing. It’s quite a humbling experience.
