Mathblogging.org Weekly Picks

We try to read every blog post that goes through Mathblogging.org. For the Weekly Picks, we collect posts in one category from last week to give you an impression of what the mathematical blogosphere has to offer. (Read this for more information on this change.)

Last week, we focused on “Pure Researchers“.

Research

• Low dimensional topology continues a series about topology of large data sets.
• Konrad Voelkel shares an introduction to Thom spaces.
• At Alpha Zero Categorical, Jason Polak starts a series on linear algebraic groups.
• Felix Breuer designs a file format for formal sketches of mathematical articles.

Community, Art

• What’s on my blackboard? has captured some snark planning.
• At Combinatorics and more, Gil Kalai congratulates Tim Gowers to his knighthood.

Exposition

• Gaussianos (translation) explains how Zeckendorf’s representation by Fibonacci numbers connects to converting miles and kilometers.
• ∑idiot’s Blog gives you Latent Dirichlet Allocation from scratch.
• At Division by Zero, Dave Richeson found a nice puzzle with a squarable region by Leonardo da Vinci.

Enjoy!
