Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.
David Montiel Canada Available View Profile Ask A Question View Past Answers	Knowledgeability 9.88 Clarity of Response 10.0 Timeliness 10.0 Politeness 10.0 Total Questions 99	PLEASE READ THIS BEFORE POSTING YOUR QUESTION: While I am glad to offer HELP with problems, I refuse to SOLVE problems. There is a difference. Please do not just copy a question from a texbook or assignment. I WILL REJECT IT. I will only accept questions, if in addition to the statement of the problem, you describe in detail what you have tried so far in order to solve it, and what exactly is the problem you are encountering. In other words where/why are you stuck? I can answer general physics questions up to the level of first or second year undergraduate courses. Topics I am familiar with include: classical mechanics (kinematics, dynamics, etc.), electricity and magnetism, optics, thermodynamics, and special relativity. I may not answer questions at an advanced undergraduate or graduate levels. Also please do not expect help with algebra or arithmetic (performing numerical calculations).
Steve Nelson U.S. Available View Profile Ask A Question View Past Answers	Rating N/A (Expert Not Accept Rating) Total Questions 1510	I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.
