I'm a graduate student in physics 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!

comment Which ball touches the ground first?
@ivy_lynx see this question (or any of the other related questions on the site) to understand why that effect is negligible.

comment Is speed of light and sound rational or irrational in nature?
@KyleStrand indeed, you're right, since unitless ratios between physical quantities are pure numbers. But as some other answers and comments also point out, the speed of sound isn't a universal constant, it depends on the conditions.

comment Is speed of light and sound rational or irrational in nature?
@Aaron I would say "the speed of light in m/s" is the product 299792458 m/s. Once you divide out the m/s it's not the speed of light anymore, it's just a number.

comment Is speed of light and sound rational or irrational in nature?
@Aaron the numeric part of the speed of light in this particular unit system, $c/(\text{m/s})$, is rational. But the speed of light itself, $c$, is not just a number so I don't think it's accurate to call it rational.

comment What are quasars?
@JohnRennie I would point out that at the bottom of the answer on that meta question, it says people might downvote questions for showing insufficient effort, but as far as I know there's nothing that says a question can be off topic for that reason.

comment Is it possible to go to graduate school in physics with a different undergrad degree?
But to add to that automatically generated comment, you can find some information on this topic at Academia. For example, see this question.

comment Is it possible to go to graduate school in physics with a different undergrad degree?
This question appears to be off-topic because it is about career advice.

comment Why do we test electric fields with positive charges and not negative ones?
@placeholder I suppose so, so I've clarified the wording, though I think it's a fairly standard convention in physics that, when talking about directed quantities like vectors, parallel means in the same direction, not just along the same axis.

comment Twins Paradox Paradox
All this is true of course, but I think it may miss the key conceptual issue, which is how the other twin can be traveling at $c$ through spacetime and yet still be on Earth to meet the traveling twin when he/she comes back.

comment Twins Paradox Paradox
I think this is actually a good question. I'm not quite sure why people are downvoting it. It comes down to the fact that the explanation you're received is not entirely accurate, but it is a common explanation, and I don't fault you for asking about it.
