One of the most exciting things about learning physics is that we get to start to try to answer "why" questions: why is the sky blue? why does the Sun rise in the East?
Learning new and modern physics can be thrilling because of the explanatory power of the theories we read about and the experiments that have been done, but sometimes we should return to these "why" questions and really examine what it means to answer a "why." One of my favorite physicists to read and learn from is Richard Feynman, and here's his take on why questions. He challenges us to consider how we answer a why question, and what implications this might have for us as students of physics. Enjoy!
