True, I mentally excluded those who use Ebay as a storefront for their easily sourced items, I was only thinking of similar items of out-of-production stuff. But now that I think about it, even some of them set a Buy It Now price that is only 20% above the usually auction price in order to get a quick sale.

Despite what I thought was a rather large vocabulary, I was frowning upon getting the recent puzzle solution of 'drupe', thinking that can't be a word and not wanting to submit it for the competition because if it's wrong, I won't get a prize, etc.

Looked it up and it is indeed a word, a botany term for types of fleshy fruit with stones like peaches, plums etc, or a small marine mollusc.

The Indian Giant Squirrel has never visited a hair salon for a dye job.

TIL that the voluntary tensor tympani muscle contraction ('ear rumbling') that I have always been able to perform, is not within everybody's power. And for me it's not even a proper 'contraction' - it's so slight that it seems almost just by thought.

TIL that the 'hornet' that flew into my front room a few months ago was most likely a hornet moth.

Sesia apiformis

This thing was sodding HUGE - easily 6cm long and so laboured in its flight I figured it was on its last legs
(although that may have been a consequence of its extreme size). I left it well alone for fear that it WAS a
big stingy thing - which is the whole point I guess!

I once built a 1/4 scale Hornet Moth, but even with its wings folded it wouldn't have fitted in the sitting room:

In re big models; I saw mention the other day of someonne who had built an R/C P51 Mustang. Fair enough, but they had built it to three quarter scale! Why not just build the real damn thing?

TIL that the original Capability Brown landscaping at Croome Court in Worcestershire had pretty much disappeared by the time the National Trust took over and an awful lot of effort has been expended to recreate it.

That an opinion without 3.14 is an onion.

A pie minus pi is energy, in that case.

Today, in fact not ten minutes ago, I learned where my effing fusebox and electricity meter is! Hidden underneath a worktop, behind a false/hinged shelf unit (no sign saying "Beware of the leopard" though...)

FFS people! You could have made it a liittle easier....

If it is actually a fusebox rather than a breaker/consumer unit it might be worth expending a little of the Crissdee Millions on getting an electrician in to replace/re-site it.

that neither π nor √2 is the most irrational number; (22/7 is a pretty good approximation as many of us will be aware) but √2 is fairly irrarional.

φ is the most irrational number (1 √5)/2

The Golden Ratio (why it is so irrational)

Having read PDR's 'PsiPhi' comment in post 1331275 I feel obliged to point out the existence of the Supergolden ratio, ψ.

φ x - x - 1= 0

ψ x - x - 1= 0
