Round photographic plates.
Caption;-
A photograph of great historical interest.
The track is one left by a positron. This positron possessed,
an energy of 63 MeV, before entering the lead plate from below;
after penetrating the 6 mm. lead plate, it proceeded with an
energy of 23 MeV. This change of energy, shows definitely,
the direction of motion of the particle and, therefore, allows
one to conclude, that it is positively charged.

Big Bertha Thing jeremiah
A film Jeremiah Johnson, not necessarily true.
A mountain man asked him, whether he was any good at skinning bears.
He said that he could skin them, faster than the mountain man could
catch them.
So running down the mountain, with a bear in hot pursuit.
His friend runs in the front door of the cabin and jumps out
the back window.

"You skin that one ... and I'll go catch me another one!"

Hi Tony
++++++
I'm afraid you are going to have to take me through all this very slowly - I did
say my
last Physics was A level some 30+ years ago didn't I?
In answer to your question, yes I'm happy to be archivist - my 486 'boasts' a
reasonable
amount of hard disk space and I could allocate about 500MB to the job with as
many backup
100MB floppies (on a zip drive) as is necessary. I'm a bit puzzled about the
email and
password bit - do you mean that I should log on as AML34 with your password and
download
your mail and files? I'm not terribly comfortable with that idea - I would much
rather
you forward the relevant messages and attachments to me rather than I should
find myself
reading all your mail.
Or perhaps it might be better to set up a closed subconference, one that can
only be
accessed by your volunteers and I would get archive the files from there.
Or you can ask people to copy them to me or mail them to me directly.
Have a think and let me know - I would rather not mess around with your mailbox
- I'm
pretty sure it's against the rules anyway!
Next
++++
I have downloaded and run the Pastures software and there are lots of things I
don't
understand (probably because I don't exactly understand the physics - and I'm
not even
going to try to do that right now - although I think I understand what your
goal is).
First thing I didn't understand was why working through the Worked Example for
Option 1 -
the seven-hour bit took my machine about 20 minutes. So either I'm missing
something
fairly fundamental or there is a much bigger speed differential between a 386
and a
486DX-66 than I would have thought!
Then as Option 4 in the Worked example was next, I tried that, but it didn't
work -
presumably because it shouldn't be next, it should be after Option 3?
When you refer to 'Edit particle.dat' are you referring to the Dos Edit command
or are you
using the term Edit more loosely than that?
Anyway, having made a miserable attempt at running the examples I decided that I
really
need my hand held on this one. I'm afraid that perhaps your documentation steps
just
aren't quite small enough for me. Would it be too much trouble to go over it
again at
half speed? If it would and I can't be of much help to you running the damn
thing, I will
still happily act as archivist because I am now quite intrigued by it all!
Cheers for now
Pam
PS I don't understand your Big Bertha messages either - and I've heard of
Serpico, there
was a not very good film made about the case a few years ago that has been doing
the
rounds on Sky.
PPS: Did you ever get Philip Sims on board? You certainly managed to alienate
a few mods
though didn't you? <<<Grin>>>
Cheers once more
Pam
