Repeat tonight of this, on Bletchley Park geniuses Bill Tutte and Tommy Flowers. Tutte was later awarded a Fellowship of @royalsociety.org.

Here’s the massive, magnificent but very rare Octobasse, invented in 1850. To play it, the musician must stand on a platform. You can hear its rather alarming deep bass tone, and see it being played, at www.youtube.com/watch?v=12X-...

Fifty years ago today saw Australia meet West Indies at The Oval in the last round of Group matches at the inaugural World Cup. Those of us of a certain age will remember Alvin Kallicharran's onslaught on Dennis Lillee (Patrick Eagar)

@gideonrachman.bsky.social shrewd on why Trump will beat Musk. But he’s wrong that this is a ‘surprise’ for Marxists. He should read Lenin and Gramsci. As Adam Tooze acknowledges, they are very relevant to understanding our era.

Proud Boys leader Enrique Tarrio tried to give a press conference to announce his lawsuit against DOJ. Much to my surprise it turned out to be the greatest press conference of all-time.
