Question
Hi Sir,

Can I assume that Ohm's Law, Kirchhoff's Law cannot be applied to micro electronic circuitry. If so , what sort of Physics and Math applies at this level?

Tq !

Answer
No, those still generally apply when the same circuit elements are addressed (capacitors, resistors, etc).  Especially Kirchoff's rules.  There are materials whose conductivity changes with applied voltage, diodes and transistors, but in general these laws are still applicable.

Expertise

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.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

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