RIP Katherine Johnson: The extraordinary NASA mathematician astronauts trusted over computers

Sean o' bhaile na gleann

RIP indeed..

101 years is a helluva innings.

Coincidentally, I sat and watched Hidden Figures only yesterday - a cracking film.

I only noticed two anachronisms - I dare say others will have noticed more.

1. The 7090 computer is described as a 'mainframe' - the term hadn't been invented back then. There weren't any 'minis' or 'micros' to compare against.

2.There's a sequence at about the 55-minute mark where two Redstones blow up, followed by another explosion... which I'm pretty sure is the Challenger disaster. There's just no mistaking the shape and colour of that fireball hurtling through the sky.
