Ask the
Physicist!
Do you have a
question related to physics? Most questions will have the answers posted at
this website. Submit your question below and I will attempt to answer as
quickly as possible. If you do not submit a valid email address, I will not
answer your question. Please read the
groundrules
for the site. If the answer is to your liking, please
consider making a donation to help support this
service. A history

New policies:
-
This site is becoming increasingly popular so it is taking up my time disproportionately to the amount of donations I have received. In future, questions which
-
violate groundrules, (Please stop sending me obvious textbook problems.)
-
that I consider to be "off the wall", or
-
are not likely to be of general interest to the many people I know read the answers
-
will simply be discarded. In the past I have tried to answer all questions even if the answer is simply that I won't or can't answer, but that is becoming too time consuming. If you don't get an answer within a week or two, you can always ask again with a "plea"; no guarantees, though.
-
If your question is clearly astronomy or astrophysics, particularly detailed questions about black holes, stellar evolution, dark matter or energy, the big bang, etc., areas in which I am not expert, I may not answer. If you google ask astronomer or ask astrophysicist you will get lots of possibilities. I recommend NASA's Ask an Astrophysicist.
The Physicist will be on an extended camping trip from June 28
until sometime at the end of July. It is unlikely that I will
answer any questions during this time but will catch up later.
