It looks … Continue reading Year of Mysteries, Part 5: Miss Smilla’s Feeling for Snow...

Seeing as linguistics is on the agenda, I thought I’d mention this excellent book I just finished, “Is That a Fish in Your Ear,” by David Bellos. Bellos is a translator and scholar of French literature, and in his book he covers all sorts of topics. Nothing deep, but, as a non-expert on the topic, […]

Shravan Vasishth, Daniela Mertzen, Lena Jäger, et al. write: Treating a result as publishable just because the p-value is less than 0.05 leads to overoptimistic expectations of replicability. These overoptimistic expectations arise due to Type M(agnitude) error: when underpowered studies yield significant results, effect size estimates are guaranteed to be exaggerated and noisy. These effects [&#...

The anthropic principle in physics states that we can derive certain properties of the world, or even the universe, based on the knowledge of our existence. The earth can’t be too hot or too cold, there needs to be oxygen and water, etc., which in turn implies certain things about our solar system, and so […]

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...
