I turned up at some pottery classes
And found them all reciting vases.
A slip of the ears
It appears.

Here’s a little puzzle, that no-one can find out,
Whether every little swing has a little roundabout.
Many years ago an aged relative passed away, and for some reason I inherited her ear trumpet. I've always treasured it, as a relic from a past era.
I've been sheltering for 12 weeks, because I am quite vulnerable.
Today I went out, at last. Infection in my locaility is down to the level just before the lockdown. So I decided that, given the good weather, it would be safe to emerge blinking into the sunlight. It could be "Now or never", with "Now" being the better option.
Here is a record of the exploration* I made on my mobility scooter.
* "X" marks a spot where a car pulled up on the other side of the road and the driver wound down the window and said "Dr Walker, I presume." Well not exactly that, it was someone I knew, who said "How are you?" but roughly similar.
My herd of Wildebeest are restless, but I keep promising them it's not long until the Gnu normal...
Brexit. Was it just a Brussels rout?

If I was or were a Toad
I wouldn’t cross the road.
I wouldn’t get frisky.
Too risky.
can u be more definite?
I asked my plumber for a quotation.
Guess what I got back. "To be or not to be".
Je sais que c'est ringard
Mais je viens de penser que
Je t'aime juste le petit lait que tu es.
I know it's cheesy
But it's just occurred to me that
I love you just the whey you are.
I was reminded of this today by a friend and colleague. The TSP problem asks how to calculate the shortest round trip between a set of cities, given the respective distances between them.
Simply comparing all the possible routes one after another will obviously work, but with even a few cities, and the fastest computer in existence, it could take thousands or millions or more years. So is there a way to solve it in a feasible length of time?
The TSP attracts a lot of attention, because it’s easily stated and most people have a gut feeling there should be a lightbulb intuition that will show the way. However decades of professional and amateur endeavour have not succeeded. We have good ways to calculate it well enough for delivery services say, but no way of finding the absolute optimum until the customer is long dead. Amazon and Google and others use algorithms which are good enough, and they are good enough; shaving 100 metres off a delivery trip will avail nought if there is a parked car en route.
So it’s a theoretical question, but to my mind they are the ones that we learn most from.
Let XKCD have the last word. This is the approach that will probably work best in this year of crisis, and perhaps at all times.
There’s a joke meme that runs, “There’s no X in Y”.
For example: “There’s no L in denial” and slightly off-colour, “There’s no P in bath”.
And in fact no X in why.
In this vein I offer, “There’s no As in bright blue skies”.
Any more suggestions? Please post in Comments.
I'm so glad dockers are exempt from quarantine rules. The're quay workers, after all.
Somebody, I don’t recall who, said “The path of honour is often insane, but it is always honourable.”
I think that kind of makes sense.
Don't understand why piano tuners aren't available.They're key workers after all.
