Mathematician Paul Erdős had a fantasy that he'd die giving a lecture.
He'd prove a result,
someone would ask about a generalization,
he'd respond "I'll leave that to the next generation," and then he'd die.
He passed away at a conference in Warsaw #OTD in 1996,
just after proving a new result. 🧪 🧮

50 years ago #OTD NASA's #Viking1 landed on #Mars: https://en.wikipedia.org/wiki/Viking_1 - here is part of the first image sent from the surface. The camera was a horizontally rotating scanner moving left to right: the early vertical columns are brighter because dust from touch-down hadn't settled yet.

15 years ago #OTD the #SpaceShuttle flew for the last time. The most elegant ship that ever carried humans to the cosmos.. and I miss her everyday.
But it's a good opportunity to remember that Atlantis namesake, the ship RV Atlantis, is still alive and working in Argentina!
