Mathblogging.org Weekly Picks

We try to read every blog post that goes through Mathblogging.org. For the Weekly Picks, we collect posts from last week that give you an impression of what the mathematical blogosphere has to offer.

Exposition, Essays etc.

• Punk Rock Operations Research gathers OR-flavored pickup lines - and did not forget to include Lem’s Cyberiad love sonnet.
• Modulo Errors simulates Lichtenberg figures (“captured lightning”) and gives you an applet for your own Christmas tree.
• Mathematical Magic gives a proof without words of a theorem of Gomory on tailless checkerboards (translation).
• cp’s mathem-o-blog analyzes the “princess on a graph” puzzle.

Education

• Angles of Reflection thinks that sometimes low tech is enough for engaging students: Using white-boards for working in groups on problems of the students choice.
• Math 老师 (lǎoshī) works out a curious identity of angles.
• I hope this old train breaks down on being the new teacher: suddenly the own opinion is not as valued as it used to be.
• yofx rocked an algebra final with a Prezi presentation.

Research

• Models of Reality asks where likelihoods come from – and despite the apparent naivite of the question, Daniel’s post is anything but.
• The Geomblog comments on the importance of publishing negative results, especially in data mining.
• mathbabe points out the implication of the conservation law of money for development of economic bubbles and the (European) financial crisis.

Community

• PhD+epsilon shares the experience of tenure reviews.
• James Colliander reports on a town hall meeting at the Canadian Mathematical Society’s Winter Meeting.
• Images des mathématiques explains why the Gaussian distribution appeared at protests in Moscow (translation).
• Peter Cameron spreads Geoff White’s idea of 50 proofs to read before you die.
• Ryan O’Donnell is developing a textbook, Analysis of Boolean Functions, publicly on wordpress — read his guest post at Computational Complexity or Gil Kalai’s impressions at Combinatorics and more.

Shorts, Shoutouts etc.

• reflectivemathsteacher celebrates its first anniversary — congrats!
• Popinga hosts the 44th Italian Carnival of Mathematics (translation).
• MathsInsider chooses its favorite online maths programs of the year.
• Gaussianos shares a Geogebra-applet for the ruler-and-compass construction of the heptadecagon (translation).
• Nuit Blanche shares a full year of posts as PDF — a whopping 872 pages!

Enjoy!
