Does Logic Apply To Hearings?

June 8, 2017


The problem of mining text for implications

2016 RSA Conference bio, speech

Michael Rogers, the head of the National Security Agency, testified before the Senate Intelligence Committee the other day about President Donald Trump. He was jointed by other heads of other intelligence agencies who also testified. Their comments were, as one would expect, widely reported.

In real time, I heard Admiral Rogers’s comments. Then I heard and read the reports about them. I am at best puzzled about what happened.

Is this a new or old paradox?

UK Independent source—and “a gentle irony”

Roger Bannister is a British neurologist. He received the first Lifetime Achievement Award from the American Academy for Neurology in 2005. Besides his extensive research and many papers in neurology, his 25 years of revising and expanding the bellwether text Clinical Neurology culminated in being added as co-author. Oh by the way, he is that Bannister who was the first person timed under 4:00 in a mile race.

Today I cover another case of “Big Data Blues” that has surfaced in my chess work, using a race-timing analogy to make it general.

Or just human ingenuity at finding patterns in ‘random’ data?

Cropped from source

Bill Clinton was the 42nd President of the United States. He came close to becoming the first First Gentleman—or whatever we will call the husband of a female president. He is also a fan of crossword puzzles, and co-authored with Victor Fleming a puzzle for this past Friday’s New York Times.

Thomas Royen is a retired professor of statistics in Schwalbach am Taunus near Frankfurt, Germany. In July 2014 he had a one-minute insight about how to prove the famous Gaussian correlation inequality (GCI) conjecture. It took one day for him to draft a full proof of the conjecture. It has taken several years for the proof to be accepted and brought to full light.

Today Ken and I hail his achievement and discuss some of its history and context.

Today we congratulate Sir Tim on his award and review the work by which the Web flew out and floated wide.
