Tuesday — time for some picks from last week!
On the expository side of blogging, Alasdair’s Musing gave an introduction on Ruth-Aaron pairs and Tito Eliatron Dixit a primer on the Vitali set (translation). Also, Mind Your Decision shared a case study of an unfriendly takeover bid gone bad.
On the researcher side of blogs, Computational Complexity asked where theorems go to die while God Plays Dice nuked a simple problem with generating functions. Regarding research, Libres pensées d’un mathématicien ordinaire reflected upon an old favorite problem and its recent solution and Nuit Blanche examined a stunning claim. You might also want to keep an eye on Gowers’s Weblog starting a new series for beginning maths students to overcome the restrictions of traditional teaching. — and check out Not Even Wrong‘s TEDx talk. Finally, Statistical Modeling, Causal Inference, and Social Science discussed yet another dubious Wegman paper.
Regarding the mathematical community, Piece of Mind and Geometry Bulletin Board followed up on the UK development and the recent letter by UK mathematicians to the Prime Minister. Frank Morgan asked for opinions on the NSF’s change of “Mathematical Sciences” to “Mathematical and Statistical Sciences”.

The week is on its way so here are some picks from last week.
First of all, you should head over to Math Accent and its fantastic crowd-sourcing project for a creative commons book! It’s less than a day to go, so hurry up and give what you can!
On the teacher side of blogs, ichoosemath taught without having the answers and Real teaching means real learning changed the definition of an exam. Continuous Everywhere but Differentiable Nowhere found the problem that never fails and Musing Mathematically shaded squares. Finally, Gyre&Gimble reflected on pre-chunking
On the researcher side of blogs, Libres pensées d’un mathématicien ordinaire remembered John Michael Hammersley while Azimuth studied Fool’s Gold. Flavors and Seasons shared a reflection on discussions and Regularize started a series on the uncertainty principle for the windowed Fourier transform. On top of that, Peter Cameron’s Blog celebrated the 1254th London Algebra Colloquium.
On the art side of blogs, Intersections shared a poem by Allison Hedge Coke and Singing Banana gave the solution to its Game of Nine. On the philosophy side, M-Phi asked if/why mathematicians should care about philosophy of mathematics.
Last but not least, Rachel Binx wrote about her data visualization work at this years MTV Video Music Awards,
Maurizio Codogno started a series on Gödel’s Incompleteness theorem (translation) and MathBlog.dk gave a short exposition on the pigeon hole principle.

It’s already Wednesday — time for some picks from last week!
On the research side of blogs, Freakonometrics looked at some old data from “The origin of sex differences in Science” — and finds the difference to be elsewhere (translation). After its epic series on the “crazy Greeks” and their geometry, Gli Studenti Oggi started a new series on how computers calculate logarithms (translation) while Computational Complexity had a guest post (and lots of discussion) from the IT History Society. Finally, Libres pensées d’un mathématicien ordinaire shared a large list of references on Markov Chains and The Geomblog saw some conference blogging via guest-writing students — best practices.
On the teacher side of blogs, Math Mambo decided to not just help, but join a student taking an online course (including fun grief). Misscalcul8 shared a conversation with Marcelle Good on textbooks. Think, Thank, Thunk shared the story of students discoverning the product rule by themselves while Exzuberant embraced Rebecca Black to make statistics a hit. Also, Learning and Teaching Maine handed out the criteria for the upcoming Math&Multimedia Carnival — deadline is Sept 23.
Elsewhere, Richard Wiseman’s Blog re-shared an amazing illusion, The Mathematical Tourist wrote about “Pythagorean Fractal Tree” by Koos Verhoeff and Math For Grownups had to endure a small shitstorm after a book review didn’t get the math right.

We are back with (a lot of) new picks!
The story making the most waves last week was probably this article on the NYT homepage on how to fix math education. It was picked up by Mathlog (in German, here is a translation), the Whizz blog, Rational Mathematics Education, dy/dan, and A Recursive Process.
Staying with math-education for a second, Lost in Recursion describes an idea of how to gain authority without overpowering the students, I Choose Math wants to give his students time to do what they feel like and decides to try different approach for correcting worksheets this year, Musing Mathematically remembers the wonders of exploring infinity for the first time, and Mr Honner continues his series on the 2011 New York State Math Regents Exams.
More essayistic texts were posted on Research Tips, seeing the necessity to change the way mathematical publishing works, Statistical Modeling, Causal Inference, and Social Science, musing about the honesty of an apology offered by an author who plagiarized himself, Computational Complexity gives examples for how to get ideas for things to work on (which, to be honest, is from two weeks ago), Azimuth fears tipping points, QED Insight rants a bit and then gives his opinion on how science and beliefs can coexist, Mind Your Decisions warns that some people making stupid choices can rig the game for everyone, and finally there was a guest-post of Barbara Jolie on Peter Cameron’s blog about randomness, followed up by a post on where randomness originates from.
Posts more exclusively concerned with mathematical research included xamuel.com on the compactness theorem, n-Category Café on Hadwiger’s theorem, Terry Tao starting a series of posts on Hilbert’s fifth problem, and Vismath (in German, translation) and 0xDE on tilings. Also noteworthy is the post on Alasdair’s Musings on Matlab-alternatives, Walking Randomly‘s report on developments in math-software in August, and two book reviews on Xi’an’s Og.
If you want to relax after reading all these posts, Mathematics for Teaching offers a nice video on mathematical patterns in nature, which goes together well with this post on La Covancha Matematica (in Spanish, translation). You might also enjoy this visualization of a very old goodie on Math Is The New Black.
Which brings us to the lighter side of math: Math Fail had some entertaining pics last week, Misscalculate wrote an ode to math, and are these the dangers of applying mathematics to real life we can see on Math Is The New Black?
If after all this you should still be hungry for more, Let’s Play Math! collected some recent Carnivals.
