First Shape Found That Can’t Pass Through Itself

Quanta Magazine has a nice article on a question I’d not even thought about – can all shapes pass through themselves? And, apparently, the answer is ‘no’, but only for a very limited number of shapes.

The article is pretty good and breaks down the problem and its history quite nicely. Go read!

The Lonely Shore / BBC (1962)

The BBC archive has just thrown up this lovely little clip. Shot in 1962, this short Ken Russel piece can only be described as a post apocalyptic archeological report. It has good fun misidentifying various pieces of 60s paraphernalia and contains a couple of sly digs at archaeology’s propensity to call anything it doesn’t understand ’religious’.

It also has a few subtle hints as to the nature of this post apocalyptic world; there’s still no mass production, no knowledge of radiation, nor (given the ignorance of the electric fire) apparently, electricity. Indeed, destruction must have been almost total – no books, no photos, no pictures. Even no real oral history.

The BFI also has a nice article on The Lonely Shore here.
