Respected Dr,Stephen... I am in 9th grade and there is a simple question in our book but its answer is not given. The question is "Why do we study Physics?" I know its a very simple question but I am searching for a perfect answer. I searched it in Internet but all the answers were of very higher level but I am in 9 grade and till 8th class we had not separate subject for Physics and it was General Science. I hope you will answer the question in simple words. Have good day.

We study physics because we're curious about how things work.  Physics is the science of how things work.  So on an intellectual level, studying physics is satisfying because it answers questions for us about how things work.  In a more practical sense, it's terribly useful for engineering.  If we need to create a machine to do a job or perform a function, knowledge of physics is where we start when we plan to build it.  This leads to all sorts of things that we find useful every day, like computers and cars.

Dr. Stephen O. Nelson


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.


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.

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