[NewCandle] that which reacteth not and is clear

[Nick Reiter]

Hi Horace and all,

Thanks very much for all your articles and thoughts. I
have not begun to catch up on them as I should, and
probably won't until the weekend.  I have to fly out
to Oakland CA tomorrow to inspect a sputter coater we
are buying at work.

I can post this empirical update for now though - 

I purchased some .1 micron Al spherical powder and
some 3.5 micron spherical as well.  Mixed up some
suspensions in ACS anhydrous ethanol, and put in small
volumetric flasks with GG vac-greased stoppers.  Spent
a couple of days trying my basic protocol - taking
weights of the flasks with the Al spherules in
swirling suspension versus settled out.  Saw no
anomalies or hints of anomaly down below .5 mg.  I do
have plenty of each powder for further variations if I
get inspired.

I won't have a laptop whilst in The Land o' Lotus
Eaters, but if my printer cartridge holds out, I will
print off some of Horace's articles and read'em as I
can.

The Holy Grail 'neath ancient Roslin waits.
The blade and chalice guarding o'er Her gates. 
Adorned in the masters' loving art, She lies;
She rests at last beneath the starry skies.
