PCR, wfw, interview candidate, wfh, start packing.
Into the office for the third day on the trot and I'm a bit knackered as I've never really agreed with early mornings. At least the coffee is free at work, but it's a classic case of you get what you pay for...
I can vouch for 'Loon - there's a round bright thing emanating from the East. I shall report it.
No lightning here, pity - damn council cutbacks, though all the rain recently has made the roads a mess, gravel everywhere.
Meetings all day, hopefully a quick run before the drinking starts
cafe three stroll uneventful, need to plan lunch
finished gluing new tubs on new wheels yesterday, may give them a go later, then i've got that set ready for hols
White sugarloaf pineapple!? On the shelf, next to the real pineapple this morning. When did this happen? Any good?
Today was my Friday which makes me very happy, lad is back from Italy and had a great time, which also makes me happy. Work is an absolute shitshow so I'm thinking about the happy things.
Fettled the MTB ahead of a pootle tomorrow, doing our usual of getting a train to Guildford or Godamnitalming and then wobbling back along the Wey towpath. Pub lunch will feature, probably a couple of other refreshment stops for good measure.

So today it’s freezing and windy,
mooched about in town, had lunch and came back for dinner.
Banach–Tarski paradox
From Wikipedia, the free encyclopedia

"Can a ball be decomposed into a finite number of point sets and reassembled into two balls identical to the original?"
The Banach–Tarski paradox is a theorem in set-theoretic geometry, which states the following: Given a solid ball in three-dimensional space, there exists a decomposition of the ball into a finite number of disjoint subsets, which can then be put back together in a different way to yield two identical copies of the original ball. Indeed, the reassembly process involves only moving the pieces around and rotating them without changing their shape. However, the pieces themselves are not "solids" in the usual sense, but infinite scatterings of points. The reconstruction can work with as few as five pieces.[1]
An alternate form of the theorem states that given any two "reasonable" solid objects (such as a small ball and a huge ball), the cut pieces of either one can be reassembled into the other. This is often stated informally as "a pea can be chopped up and reassembled into the Sun" and called the "pea and the Sun paradox".
2nd paragraph. If you can understand it, let me know 'cos I don't.
Edit: just encountered a very busily munching (and sneezing) hedgepig, first time this year actually to see one eating, the food's been going steadily for weeks now. Forza Spike.
