I'm a post-doctoral researcher with a wide range of interests. My career is in complex systems science (or maybe cybernetics) and the origins of life, but I also have research interests in

  • the foundations of statistical mechanics and its relationship to information theory
  • Earth systems science
  • non-equilibrium thermodynamics in general

I'm also generally interested in the foundations of quantum mechanics and in black holes, though I wouldn't say I'm an expert on those things.

It's probably worth noting that despite the fact that my research is in physics-related areas, all my degrees are in other subjects. If I occasionally seem to start talking in an alien language, this is probably why.

comment Is there an upper limit to a rocket's size/payload?
@KyleKanos I've fixed the answer so that it explains the issue with gravitational acceleration properly, and also explains why Asad's answer to the linked question is wrong (and yours is right).

comment Why is there water coming out of a car’s tail pipe?
@TimS I meant by volume, which is proportional to mole number for gases.

comment Is there an upper limit to a rocket's size/payload?
@KyleKanos thanks, you're right that I should have included the gravitational acceleration in the equation. But unless I misunderstood it on my quick reading, I don't really agree with Asad's answer. He assumes the burn rate remains constant as the rocket size changes, which seems a weird assumption to me. If you let it scale proportionally to the mass you still end up with $m_f$ times a constant, as in my answer.

comment How is the logarithmic correction to the entropy of a non extremal black hole derived?
I wonder what this looks like in non-Planck units. There must be a bunch of constants inside that $\ln$ to make its argument dimensionless, and knowing what they are might give some insight into your question. (I know this is old, but just saying.)

comment Why does sand stick to my shoes?
I don't know for sure but I always assumed it's because salt crystallises out as the water evaporates. The test would be to use pure silica sand wetted with pure water, and see if it sticks to clean shoes.

comment Why isn't the best case classical solution to the CHSH game 100%?
This is getting silly. How can a question about the CHSH game be off topic on a physics site? The idea that questions have to be "about physics" has always been a bit flaky (i.e. blatantly subjective), but if you're going to draw the line here it's just ridiculous.
