When my mother once asked me why I wanted to go to MIT I answered that I wanted to find out how everything in the world worked. I am still learning how things work and I am still enjoying the search.
Through the years I have have been asked great questions by many friends, most of whom are high school physics teachers. Some of these questions come from the teachers, others come from their students. Either way I feel privileged to receive questions. Each question is a valued treasure. On these pages I will present some of the attempts I have made to answer these questions. I have learned a lot in the process of writing these answers and I am always ready to learn more if others have comments.
You can always find answers to these questions using mathematics in physics textbooks. My goal is to provide answers which are not wrong and which guide people to understand a little better. I try to answer with words and drawings and images but lurking behind my answers is the mathematical description of nature.
