I'm a PhD student in biomathematics, working on stochastic individual-based models of evolution in spatially structured populations. My other interests include cryptography, programming games and puzzles, photography and graphic design.


I'm the main author and maintainer of the Stack Overflow Unofficial Patch (SOUP), a user script for browsers with GreaseMonkey-compatible user script support (Firefox, Chrome, Opera, possibly Safari) that fixes or works around a number of outstanding issues with the Stack Exchange user interface.

I tend to answer a lot more questions than I ask. Some answers I'm rather proud of:

CC-Zero Please consider any (original) code I post to Stack Overflow and other Stack Exchange sites to be released under CC-Zero unless stated otherwise. You may do whatever you want with it and don't have to credit me in any way, although of course that would be nice.

comment Do the probability density and the probability current density have a unit
By "(probability) current density", I assume the OP was referring to (probability) flux, which would have units of base quantity per "area" (= surface of a "volume") per time. Of course, $A/m^2 = C/m^2/s$ is a unit of (electric charge) flux, the 1/time part is just hidden inside the definition of the ampere.

comment Why does intramolecular hydrogen bonding cause molecules to separate?
Anyway, I do think that this is a pretty pure chemistry question -- it's not really even "physical chemistry", as the term is conventionally understood -- and, given that it already has a good answer, it might in fact be worth migrating. Yes, I know it could be argued to be on topic here too, but IMO the only real argument to be made for that is that "chemistry is a subset of physics, and so all chemistry questions are on topic", a view which I don't really consider very productive in practice.

@Chris: IME, mods on most sites don't much like being bothered to migrate questions that could've been "self-migrated" (i.e. deleted and reposted on the other site) by the OP. But, yes, cross-posting as such (i.e. having the same question active on two sites) is generally somewhat disliked. In those rare cases where it may be justified, e.g. to get answers from two very different communities (like, say, Christianity vs. Role-playing Games), it's best to explicitly note it in the respective posts.

swap "intermolecular" <-> "intramolecular"; based on answer and comments, they were clearly backwards; misc. copyedits

this has nothing to do with thermodynamics

comment Why aren't units with powers, like cm³, surrounded by parentheses?
@supercat: The IEC binary prefixes exist precisely for that purpose. If you mean $16 \times 2^{20}$ bytes, write 16 MiB; if you mean $16 \times 10^{6}$ bytes, write 16 MB without the "i".

comment Why aren't units with powers, like cm³, surrounded by parentheses?
@supercat: According to the current ISO/IEC standard, $4\,{\rm kB/s}$ $=$ $4{,}000\,{\rm B/s} $ $\ne$ $4{,}096\,{\rm B/s}$ $=$ $4\,{\rm KiB/s}$.
