There is large body of work from the mid 1980s and early 1990s that addresses the question of hardness, sensitivity and robustness from various statistical physics/computer science collaborations. Of course, it is still ongoing, but th

To get the effect I was referring to, yes it is too strict a class. I wasn't thinking very hard about it, but my idea was that conformal transformation have nice compositional properties, which could be exploited in developing the meth

This is very interesting. I wonder if anyone knows what can be gained in terms of separating out different topologies by allowing for a restricted family of conformal transformation on top of the tanh functions, of the sort that allows taki

This looks like an excellent product. I think I might try it out. I say "I think" because I wonder whether or not it might be too small for the things I would use it for. Might there be an option for larger (say A4 or US Letter si

The IPython notebook is not quite a full blown IDE, but does support precisely this feature. Notably the notebook can support a Julia backend. For certain types of work one might prefer this kind of thing to an IDE.

The point of this game is to lose in the fewest number of steps.

You mean 5 figure loans right? Five figures are quite common (I am paying one off myself) but I think 6 is really quite rare. In any case, with few exceptions tuition money does not get used to conduct any kind of research. Most of it will

Hey, thanks. This was a fun problem. I got a little bit obsessed though, and I wonder if it might be possible to finish the problem on pencil and paper. I am sure I can finish an approximate version, but I am not sure I can get 12 digits. D

The Wikipedia article on the method used to calculate this sum mentions applications to quantum field theory [1]. Links to applications might be an interesting category of metadata for Wikipedia math articles which could be semi-automatical

I don't know of any use behind the calculation of the value for this particular series. But Ramanujan summation (and other summation methods for divergent series) show up in the renormalization calculations in field theories. So this m

Which assumptions were weak? I'm not sure what the comment has to do with the US, but the Russophone world is well aware of the importance of this problem to the effect that one would expect news of any consensus on the validity of thi

Very cool. I thought to myself, before clicking on the article, "this is Hacker News, so its probably some interesting number theoretic sieve... but then again there are a lot of people who like to cook so maybe its some kind of novel

I think I completely agree with you. As you point out, one expects that there is a small but finite probability to have Boltzmann brain-like things pop up in the universe. And if it did happen it would violate the second law, which is maki

This is pretty silly. The ``paradox'' only arises because of a confused notion an apparent incongruity between the second law of thermodynamics and the subjective perception that complex "things" in the universe (rivers,

I think I can understand what you mean about worrying about the lack of emphasis of functional programming in Julia, in the sense that it certainly isn't emphasized explicitly, but I wonder if your concern is more specific than that? I

If you already have a background in each of Ruby ,Python, Haskell and Haskell you probably can learn a good chunk of Clojure in a weekend, as it shares many features with these languages. The main difference, of course, is the prominence of

Well, what would happen is that the clone would commence a depth first walk down the path of the original's imagined task graph and probably overdose on some stimulant while trying to prove the Riemann hypothesis. I found the story in

It may indeed be a strange choice, but I think there are many reasons for why one might try Julia beyond the speed aspect. The main one for me (and I think the language designs also state something to this effect) is the language wide parad

I only skimmed the article until I saw "lein new", so I have no comment on anything before that. But I did want to say that I liked the explanation of the tree structure with the English language example. I think I might steal it.

This particular professor, as far as I am aware, would probably not be considered as active in QFT. He has been working on turbulence and chaos recent (albeit, employing techniques from field theory). At any rate, I don't really see th

This is a very good point and I think I would like to refine my comment in response to it. I think it is important to distinguish between individual vs collective accountability, as well as accountability within a field and the accountabili
