I do not respond to off-site contact about moderation. Any moderation questions or comments should go on meta, or bring it up in chat.

I'm a postdoc doing research in high-energy particle physics. I also have a hobby interest in computer programming.

You can find me on Twitter, or check out my blog and personal website! Or you can email me at stack@ellipsix.net.

comment M-theory and Mathematics
@Qmechanic I'm curious as to why you added soft-question? I don't think it applies here. Perhaps the question is off topic (philosophy), but it doesn't seem to be soft.

comment Shouldn't dark matter distort light and there for be directly detectable?
@dmckee I think that's most of the way to being an answer. (I guess it's kind of the answer I posted, but still. As usual, don't take mine as any sort of admonition not to post your own answer if you like!)

comment Physically, what causes joint pain?
I think this is off topic. It might go on Biology though.

comment Dr. Pierre-Marie Robitaille: On the Validity of Kirchhoff's Law
No, I didn't watch the video, and I shouldn't need to. Questions should be self-contained. In any case, the title you had before made it seem like you were claiming Kirchoff's law was wrong, and that's what that part of my comment was about.

What have you done to try to figure out the answer yourself?

comment Dr. Pierre-Marie Robitaille: On the Validity of Kirchhoff's Law
The main aspect of this question seems to be "What do you think about this?" which makes it too opinion-based IMO. I think if you reword it to ask about the validity of the physics, it could be better, and reopenable. Also, the title isn't doing you any favors, claiming that a part of established physics is wrong.

comment Why, fundamentally, are particles charged?
What sort of satisfactory answer could you get that wouldn't cause you just ask why that is the case?

comment Does spaghettification really happen with conditions found close to a black hole?
@Asher that should probably be an answer

comment Why don't photons split up into multiple lower energy versions of themselves?
I think it's worth mentioning the collinear case more prominently. The equivalent process with gluons plays a large role in QCD.

comment What are quarks made of?
@BT and Ron: I've moved the comments to a chat room, so if you two really want to keep going in this vein, do it there, but consider this a reminder that rudeness (as exemplified by a few of the moved comments) is not acceptable on this site.

revised It is possible to have a situiation in which $|\mathrm{d}v/\mathrm{d}t|$ is not zero but $\mathrm{d}|v|/\mathrm{d}t$ is?

comment Would a fast moving (approaching $c$) stream of particles be affected by the gravitational pull of a gas giant?
Hi, and welcome to Physics Stack Exchange! Did you try anything to figure out the answer yourself? If so, you should mention it in the question. We expect people to do a certain amount of investigating on their own before posting here, and the answer to this should be easily available in many other places.

comment Laws first, matter and energy second?
I'm voting to close this question as off-topic because it appears to be about philosophy.

comment Is it physics that leads to development of maths or is it maths that leads to the development of physics?
I think this is off topic, though it might fit at History of Science and Mathematics.
