Isn't that science rather than logic?

My fault. When I filled in the request form to the department in charge of colouration I wrote "blue" instead of "puce" which I originally intended

Alan - is this like "Why is the sea wet?" (because the sea weed) or does it have a sensible answer?

Yes Everso. There is no sky, except in your mind. Clouds yes but the blue sky is just white light refracted through the atmosphere.

An easier one. Put a wooden spoon and a metal spoon in the freeze overnight. Blindfold your spouse or assistant then place one spoon in each hand and ask which is the colder. 10 to 1 you will get the wrong answer.

(By the way, it works best with a scantily-clad assistant. Just a little insider tip there, even though I'm risking my Magic Circle privileges.)

I've just been googling "Is the sky blue - logical thinking" and got myself tied up on a logical thinking website. I gave up because I find thinking logically hurts my brain.

Is it still there when you close your eyes. Get your scantily-clad assistant out in the sunshine for this and tell her it is a high frequency wave (bye bye) hitting her retina and rushing up her optic nerve to tell your brain. Her brain will yawn and say 'I call that frequency blue' .

But is MY blue the same as YOUR blue? We will never know.

You may not believe me Everso, but I worked this out in a hotel bed in St. Helens after a printing crew asked me why it is blue. Strange, printers neven know anything about colour.

But is MY blue the same as YOUR blue? We will never know. Exactly! that is the main point. How do you know it is 'blue'? Your Mummy told you.

When YOU'RE looking at the sky you might see it as (what I would call) green. But because you call it blue then it's blue to me. But I'll tell you what, my blood has a bluish tinge.

Quite, bear that in mind an let us return to Weyland's scantily clothed model. Suggest you wear gloves for this. Ask her/him to open their hands and place one spoon in each hand and, when she/he stops dancing ask which was the colder. Was the metal colder the wood or vice versa?
