Seiriol, who was then and no doubt is now a uniquely gruff man, summoned me to his office with an email entitled something like TRIVIA ENTERS MY CONSCIOUSNESS, ENGENDERS FURY. So I turned up at the appointed hour, quaking, and ignoring as best I could his theatrical stack of empty whisky bottles. 2/

"Years and years ago, there was a production of The Tempest, out of doors, at an Oxford college on a lawn, which was the stage, and the lawn went back towards the lake in the grounds of the college, and the play began in natural light. But as it developed, and as it became time for Ariel to say his farewell to the world of The Tempest, the evening had started to close in and there was some artificial lighting coming on. And as Ariel uttered his last speech, he turned and he ran across the grass, and he got to the edge of the lake and he just kept running across the top of the water β€” the producer having thoughtfully provided a kind of walkway an inch beneath the water. And you could see and you could hear the plish, plash as he ran away from you across the top of the lake, until the gloom enveloped him and he disappeared from your view.
And as he did so, from the further shore, a firework rocket was ignited, and it went whoosh into the air, and high up there it burst into lots of sparks, and all the sparks went out, and he had gone.

"When you look up the stage directions, it says, 'Exit Ariel.”

Eleven years ago, I wrote to Tom Stoppard to ask about this coup de théÒtre from 1949. It took me down an unexpected rabbit hole - in memory of Stoppard, here's what I found.

I don’t know a lot.

But I know a lot about dinosaurs.

Now we all know dinosaurs lived for millions of years right?

But does you mind actually wrap around how long they dominated for?

Lets get a little perspective.

Did you know Allosaurus never saw flowers but T.rex did?

Sure, but journals have some criterion they use to decide when a published article falls so far beneath basic expected standards that it should be retracted. So likewise they should consider setting some standards that referees are expected to meet, such that failing leads to losing anonymity

I have two apps side by side on my homescreen, one for remembering films I want to see and one for logging films when I've seen them, and I never ever ever remember that the app to click on when I've just watched a film is not the app called JustWatch

When people complain about inflation it's a kind of indirection β€” they don't care that the rate of change of prices is ticking up or down, they really just want lower prices

The exact same thing is going on when the far right complain about immigration
