Not all these blogs are popular, so I figured a link dump was in order:
Social Science Statistics Blog, Correlation is Not Causation, Part 1,345,649,303. It made me laugh.
MathsClass, Bearing and airports. A Dan Meyer-like “here’s a picture figure out what it means” exploration of the numbering of airport runways.
Rip’s Applied Mathematics Blog, Color: odds and ends. Additive and subtractive colors, and how they can be manipulated like vectors.
Calculus I Blog, Early Method for Finding Tangents. Post from a student blog about finding tangents without Calculus.
Division by Zero, Top 8 Most Popular Polygons. Fun with Google Trends: poor, unloved nonagon.
y of x, What Would a Spectator Friendly Math Competition Look Like? Going above and beyond the thrill of pencil and paper.
Maths: The Final Frontier, Wheels within wheels: A gallery of epicycles. Just lovely.
neverendingbooks, The Scottish Solids Hoax. Neolithic Platonic solids, or wishful thinking?
