You're correct: Wired has hyped the original title of the article in Quanta Magazine: "A Path Less Taken to the Peak of the Math World". Any time you see the words "Math Genius" you should assume hyperbole. If you l

"A Wavelet Tour of Signal Processing" by Stephan Mallat is pretty good if you've got a background in signal processing at the undergrad EE level. Math heavy CS may require some recollection of linear algebra and numerical alg

Keep it up. I had a similar experience. Even through my PhD at a top-tier school in applied math, I didn't do "all-nighters" or cram sessions. In fact, after my first 2 years of PhD (where I regularly put in 80 hours a week b

Interesting. How does arbital see itself in relation to Wikipedia's math pages? It seems like you are trying to make it more accessible, like the Wikipedia simplified English descriptions

Anyone have any details? I'm curious how much acqui-hires go for these days.

This confirms Elsevier's status as the most avaricious publisher, accounting for more than one-third of Finland's overall subscription costs. Wiley comes in a distance second at 10%. Many academics, particularly in mathematics, ha

I may be misunderstanding, but the author asserts that Sydney and San Francisco are real (or rather, they have referents), and I'm confused because, in particular, Sydney and San Francisco are real in essentially the same way that numb

So... the assertion is that physical things are real and numbers are not? It's alluring to accept this axiom, but when challenging a platonic view of mathematics, I don't think that we should accept that without discussion. In oth

> if you want to say something is true, you always need to know what difference it makes. Absolutely. It seems that fictionalism avoids both the "in some sense" qualifications and worrying about what difference it makes by asse

It is interesting to interpret the body of mathematics as you would a collection of fictional tales. However, the philosophy begins to unravel (to me) when it asserts that "8 is larger than 5" is false while "Sydney is larger

This article appears to be bent on buttressing an anti-scientific religious viewpoint rather than improving science. (Read the last few paragraphs.) The conclusion strikes the same themes that I've seen many times in the religious ant

This relates closely to the [Darpa Spectrum Challenge]( http://archive.darpa.mil/spectrumchallenge/ ) that I participated in a couple years ago. The goal was to transmit information in a congested and contested RF enviro

This is the crankiest comment I've seen on HN in a while. You "know Fields medalists"? Right. You think that Pricipia Mathematica is the source of all truth in mathematics? Wrong. Most mathematicians working on foundational q

I don't really see a compelling case for this method. The empirical convergence rates are clearly polynomial, while subspace iteration (e.g., Krylov) are "in theory" exponential and in practice pretty good. There is a bit of

Thanks for the edit. Of course an even number isn't prime ;)
