I have constructed a Czech math joke!

"One such study, recently published in the European Journal of Social , failed to find evidence that stereotype threat significantly impaired ’s inhibitory control and performance.

... “The ‘answers’ appear to be more complex than I had originally hoped, however. My has found mixed evidence for the theory of threat, and large-scale replication studies have sparked controversy over the robustness of this phenomenon.”"

Happy Black Friday. As is traditional, wear hooded black robes and listen only to Norwegian black metal music today.

this result will surprise literally nobody but it's still important

"Reviewer bias in single- versus double-blind peer review"

pnas.org/content/early/2017/11

spoilerssss: " ... single-blind reviewers are significantly more likely than their double-blind counterparts to recommend for acceptance papers from famous authors, top universities, and top companies. The estimated odds multipliers are tangible, at 1.63, 1.58, and 2.10, respectively."

😱

The "efficiency gap" makes sense only if you think 3--1 majorities are ideal.

@webmind Now you have to figure out if I boosted ironically or not ;).

Is it just me or is it rather annoying to have people asking for boosts. I'm less inclined to boost if you ask. I'll boost if i want to spread the info. Fav if i like or want to remember. Def not joining the chainletter stupidity.

A Schnyder wood and the resulting straight-line grid embedding of a planar triangulation.

Counting in balanced ternary, from Michael Stifel's Arithmetica Integra, published in 1544. This is part of a general discussion of manipulation of numbers as sums of elements in a geometric series.

The next chapter describes algorithms for computing square roots, cube roots, and so on. A modern formulation of Stifel's algorithms would involve binomial coefficients, so of course Stifel provides a handy illustration of "Pascal's" triangle.

Pricking the Garter: A centuries-old application of the Jordan Curve Theorem. This *might* be the game "fast and loose" that Shakespeare referred to in several of his plays. Jordan published his proof of his eponymous theorem in 1906, although it was formally stated by Bolzano about 60 years earlier, and implicitly assumed by Euclid. This is also a precursor of the textbook parity-based point-in-polygon algorithm discovered by Gauss in the 1840s.
