Orwell Notes Hitler's Rigidity of Mind

It is a sign of the speed at which events are moving that Hurst and Blackett’s unexpurgated edition of Mein Kampf, published only a year ago, is edited from a pro-Hitler angle.

He had crushed the German labour movement, and for that the property-owning classes were willing to forgive him almost anyth...

 Climate Forecasts vs Projections

"Projections are essential for giving us information on long-term trends, but the timescale is beyond what many policy makers (and the public) consider to be relevant to their decision-making processes.

The current best estimate for the age of our universe is between about 10 billion and 20 billion years, which is plenty long enough. It turns out, however, that it is not so easy a priori to design a universe that expands, as our universe ...
