I will do your math, physics, or engineering problems

Hi! I would like to work on your mathematics, physics, or engineering problems (easy or difficult). I have a doctorate (Ph.D.) in physics from an Ivy League university, and I have bachelor's of science (B.S.) in electrical engineering and engineering physics from a very well-known engineering school. By day, I work as an engineer at a large semiconductor manufacturing company. I enjoy solving science and technical problems, so let me hear your proposal!

NOTE: Please message me first before buying a gig! This is important, because I do not accept all job requests, and I am sometimes out of town! Thank you!

UPDATE: Please do not expect your quote to be a single gig. If you have one simple question, then it will be 1 gig. If you ask multiple questions of varying difficulty (especially if many take a long time to hash through), then your estimate will be much higher. I will weigh the length and difficulty of your request and give you a reasonable estimate based upon my assessment. Thanks!
