## Battle of the cozy comedians: What’s Alan Bennett’s problem with Stewart Lee?

July 22, 2014
By

When in London awhile ago I picked up the book, “How I Escaped My Certain Fate: The Life and Deaths of a Stand-Up Comedian,” by Stewart Lee. I’d never heard of the guy but the book was sitting there, it had good blurbs, and from a quick flip-through it looked interesting. Now that I’ve read […] The post Battle of the cozy comedians: What’s Alan Bennett’s problem with Stewart Lee?…

July 21, 2014
By

I am a statistician, but I have worked in a department of predominantly econometricians for the past 17 years. It is a little like an Australian visiting the United States. Initially, it seems that we talk the same language, do the same sorts of things, and have a very similar culture. But the longer you stay there, the more you realise there are differences that run deep and affect the…

An empty matrix is a matrix that has zero rows and zero columns.
