Quad VDW Theorem: For all c there exists W=W(c) such that for all c-colorings of {1,...,W} there exists a,d such that a and a+d2 are the same color. What is known about W(c)? The first proof of Quad VDW was nonconstructive. The second proof was constructive but used VDW's theorem and gave terrible bounds, even for W(2). EASY: Show W(2)=5 ON A HS MATH COMP: Show that for all 3-colorings of {1,...,2...

This came up in comments recently so I thought I’d clarify the point. Mister P is MRP, multilevel regression and poststratification. The idea goes like this: 1.

In 1937, a year after Turing had his seminal paper, Ronald Coase published a paper The Nature of the Firm to give a framework to why we have companies and how large they become. In a perfect market economy we shouldn't need a firm at all, everyone is just an independent contractor and market pricing will drive efficient use of labor. Coase notes there are costs to creating contracts and one can ga...
