My email has been sending out scam messages recently (advertising Amazon). I had to change my password. I hope it is now OK. Probably this was due to me being a former M&S online customer (their site was hacked).

Why don't we let Ukraine into NATO and call Putin's bluff? Stop all this pussyfooting around.

I can't find "Hymns of Modern Thought" in the online catalogue. There used to be several copies in the Library. My online version is however still available on the website: www.leicestersecularsociety.org.uk/PHP_redirect...

Since I was involved in cataloguing the LSS Library some years ago. I was hoping to come to this meeting but have not felt well enough to travel in this heat. It's good to see the improvements being made. I would recommend the biography of George Eliot.

Besides these 'reflecting' pieces which are treated like billiard balls it is also possible to have 'diffracting' pieces that are treated like point particles. They go right to the board edge. So they hit at the corner of a cell and come out on a different colour. No one has done much with these.

Surely if you invert the first two columns of the first example you get a 3x4 with 2 of each tile. Or is there an extra condition not stated?

It seems obvious that Trump has been brain-washed or hypnotized by Putin. He always comes back to repeating the Russian propaganda, that Ukraine started the war, despite knowing it was Russia that launched the attack.

This reminds me of the scene in Indiana Jones where a dervish challenges him with a display of knife wielding, and he just gets out his gun and shoots him.

I've noticed that the same happes on YouTube, where a new related video (or a different version of it) follows immediately after the first one ends, with hardly a pause. I suppose it's all part of the algorithm which reinforces what ever you have been watching before, and offers more of the same.

You can also have a Slip-Bishop or Slip-Queen which goes to the 1st, 3rd, 5th, ..., cells. Similarly a Skip-piece goes to 2nd, 4th, 6th, ... (also known as Dababbarider, Alfilrider, etc). Also Ski-pieces (my own invention) are Rook, Bishop, Queen that miss out the 1st cell in the ride.

Fear of Ideas! The rule of Ignorance in the USA gets more alarming. Our openness to the free flow of ideas, and their rational evaluation, is one of our strengths in the UK.

The panda was introduced by David Parlett who described it as a rook that moves only to squares of opposite colour to that on which it stands. There is a problem by JJSecker in The Problemist 1977. Slip-Rook is my term for the piece.
