Expert Profile: Steve Nelson

Expertise: Ph.D. from Duke University in Physics. Explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties. Homework I may be able to give you a start on with a general category of question but I will not answer any specific question with actual numbers, etc (please don't ask if that's what you want).

Experience in the area
I'm a physics professor, research in nuclear astrophysics. I teach physics, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.

Thanks so much. We will be able to use the hair dryer idea pretty easily. Hubby is trying to purchase a boat, but is unfamiliar with this type of co

Thank you! I've wondered about that for quite a while.

2008-11-20 Help!: Never seen a lab quite like that, so it would help if you followed up with some more details, but I'll take a stab at helpin' ya out here. I'm going to guess that you had to measure the weight (gravitational...

2008-11-20 boat hull: That would work, probably. Air in the upper parts of the hull would significantly muffle the sound compared to water. The best measure would be a change of the speed of sound. Another method would be...

2008-11-20 electromagnetism: You'll have to look up the maximum amperage or the starting amperage of the battery for the car you're referring to, and either measure or estimate the wire radius (probably under 1 cm) and make sure everything...

2008-11-20 boat hull: Yes, estimate the volume of the balsa (area estimate times thickness) and do the same for the fiberglass. Balsa's density is about 100–200 kg/m^3, Fiberglass is about 1900 kg/m^3. Multiply density by...

2008-11-19 Query about the electromagnetic forces.: Wow, you really asked a difficult question to answer. Unfortunately, the actual answer to this question is a subject which would require courses in quantum mechanics and likely quantum electrodynamics...
