Experimental nuclear and particle physicist. These days I'm teaching, but I've spent a lot of time on nucleon structure in fixed target electron scattering and neutrino oscillations using reactors and beam sources.

comment How can I measure the mass of the Earth at home?
Given that the policy that many edits makes CW has been dropped I have removed the wiki status from this post.

comment Does a Michelson-Morley experiment uphold mass-energy equivalence and special relativity?

comment Is there such a thing as purple light?
It is always worth remembering that the brain does a lot of processing on a set of sparse and limited signals, but then we try to explain the sensations of color with fairly simple models. It should not e surprising that there are corner cases in which our models err.

comment Does mass increase at relativistic OUTSIDE of the mass's frame of reference?
You have misunderstood at least half the answers to the many, many other questions on this topic. There are two ways to define mass in these contexts and the question has been repeatedly and correctly answered for both ways.

In all seriousness he is lucky that we have a new tool which lets us manually move comment threads.

comment What is $Q_p/Q_e$ experimentally?
No doubt because it complicates the uncertainty expression, and with the difference being valued at $10^{-21}$ or less it simply doesn't matter to the result.

simplify at the end as we have already used the relevant approximation.

Have you looked in the Review of Particle Physics? That is always the first place to check for these kinds of things.

comment Energy and work
"Work is just a synonym of energy" Er ... no. You've got it right in the rest of your post, but the words are not synonymous and they can not be interchanged. You can not say "The force does 5 J of energy to the body", nor "The rock has 5 Joules of work".

Neutrinos do have mass in every sense of the word.

comment Why does electromagnetic refraction happen?
The underlying physics is Huygen's principle. In fact the answer to almost every "Why does ..." question in optics in Huygen's principle. It is usually underplayed in basic treatments (I think because you have to understand it's application to appreciate it and you have to appreciate it to understand it's application), but it is really important.
