An Introduction

  1. Jul 27, 2016 #1

    My name is Troy. I am a mechanical engineer in between jobs, and have an interest in astronomy and aquaria. I have joined primarily because I have a specific question about light which could not be resolved by google, I have seen physics four a few times before, and hope that this will be the best way to get a straight answer for my question.
