ABSTRACT
Learning something new can be exciting and exhilarating, but it can also be tiring and frustrating. In my dad's case, it can also be embarrassing. It changes with a teacher/guide/mentor. Teachers inspire, challenge, and help push learners to active experimentation, even when we as learners aren't sure about our perceived skills. Copernicus comes around and drops a knowledge bomb on the entire world (while on his deathbed) when he publishes a book supporting his "Sun as the center of the solar system" theory in 1543. Well, no one believes him. They call it heresy. And most people go about their business the same as before. By 1650, most astronomers (thanks to Galileo's efforts) believed the science supported the heliocentric view on the world, and helped persuade the public on the validity of this theory. As humans, we've always had to unlearn. The problem is that unlearning is hard. It rails against our biases.
