Very far OT

Thanks for the url, I've bookmarked it. I tried to respond to you personally, but the msg wouldn't go through. I don't know how to change "munged" e-mail addresses to make them work. Jerry 47

A friend, who is wintering in Mexico, the luck dog, E-mailed me a request for a name. I don't know and Google, probably to my incorrect parameters hasn't produced a result. What he wants to know is the name of the form or figure as he describes it below. Engineers? Any help appreciated.

Cheers all - Jim.

If one takes a strip of paper (or any other material) say about a 1/2" wide and say 12" long and, holding one end firmly gives the other end one twist, then attaches the two ends together, one now has an object that has been changed from two-sided - duel-plane (a top and a bottom) to a single side or plane. For if one now traces the surface of this strip with a finger one will be able to transverse both 'sides' of the strip without removing the finger from the surface, as it now has only one plane - one continuous 'side'.

mobius strip.

Or rather - to be pedantic about it - a Möbius strip, after the mathematician who devised it :) Chek Change' boos' to 'bos' in address to email directly

Once again thanks all. Much appreciated. Cheers - Jim.

This rarely works on PCs because the ALT key (equiv to Mac's Option) is often usurped by program-key combinations. Other Mac tricks include Option n to get a ~ over an 'n', Option e to accent a vowel and Option i for a circumflex. The other Option combinations tend to give variant characters, such as o, a, oe, ae and so on. My personal favorite is the Option semicolon, because it allows me to trail off after contributing to thread drift...

Ever read the 'Barmy Jeffers' kids books by J.H. Brennan? He uses a Mobius Strip to go to another world...

Hmmm. I have the Damon Knight "100 years of SF" in a 2-part paperback edition, by Pan. A good collection with some rarities in it (Kipling, "With The Night Mail" for instance).

In the same vein but with an extra dimension, Robert Heinlein's "...And He Built A Crooked House" depicts an architect's whimsical house, built in the shape of an unfolded tesseract (a four-dimensional cube): - in Los Angeles. There is a small earthquake - and I'll leave the rest as an exercise for the reader :-)

yes, i have the knight also. crooked house is in the heinlein anthology unpleasant preofession of johnathan hoag. really goof bunch of stories......

ooooooops, good bunch of stories.
