Hunting Complexity in Zeta

December 20, 2016

A second look at Voronin’s amazing universality theorem


Anatoly Karatsuba and Sergei Voronin wrote a book on Bernhard Riemann’s zeta function. The book was translated into English by Neal Koblitz in 1992. Among its special content is expanded treatment of an amazing universality theorem about the classic zeta function proved by Voronin in 1975. We covered it four years ago.

Today Ken and I take a second look and explore a possible connection to complexity theory.

Bletchley Park

December 12, 2016

Lessons from the Park that still apply today


Iain Standen is the CEO of the Bletchley Park Trust, which is responsible for the restoration of the Park. After the war, the Park was almost completely destroyed and forgotten—partially at least for security reasons. Luckily it was just barely saved and is now a wonderful place to visit and see how such a small place helped change history.

Today I would like to report on a recent trip to Bletchley Park.

Magnus and the Turkey Grinder

December 8, 2016

With part II of our “When Data Serves Turkey” post

Baku Olympiad source—note similarity to this

Magnus Carlsen last week retained his title of World Chess Champion. His match against challenger Sergey Karjakin had finished 6–6 after twelve games at “Standard” time controls, but he prevailed 3–1 in a four-game tiebreak series at “Rapid” time controls. Each game took an hour or hour-plus under a budget of 25 minutes plus 10 extra seconds for each move played.

Today we congratulate Carlsen and give the second half of our post on large data being anomalous. Read more…

When Data Serves Turkey

November 30, 2016

A head-scratching inconsistency in large amounts of chess data

Slate source

Benjamin Franklin was the first American scientist and was sometimes called “The First American.” He also admired the American turkey, counter to our connotation of “turkey” as an awkward failure.

Today I wonder what advice Ben would give on an awkward, “frankly shocking,” situation with my large-scale chess data. This post is in two parts.

Theorems and Proofs—which are more important?


Ken and I wish to thank all who read and follow us. May you have a wonderful day today all day.

But we would like to pose a basic question about teaching complexity theory: Theorems vs. Proofs.

Unskewing the Election

November 8, 2016

Not the polls but voter impulse this time

Cropped from source

Nate Silver has gone out on a limb. Four years ago we posted on how the forecast of his team at FiveThirtyEight jibed with polls and forecasts by other poll aggregators. This year there is no jibe.

Today, Election Day in the USA, we discuss the state of those stating the state of the election.
