[committee] Tech talk

[Andrew Williams]

Hi, just following up on a discussion at the 50th dinner, about my 
giving a tech talk at UCC one evening. I gave one in 2019 about the 
Murchison Widefield Array radio telescope and a bit about the SKA, but a 
lot's changed since then, and I'd be happy to do an updated talk.

Monday, Wednesday or Friday nights suit me best, whatever works for you 
guys.

Andrew
