It wasn’t my intention to incite a holy war. I am at this minute pleading redemption at the altar of the great Slug. Have made my ritual offering of circular slide rules (with handy conversion tables on the back) and have been chanting from the Cambridge four figure log tables but to no avail. I fear the only atonement is to sacrifice my HP32s2 by ritualistic dismemberment (just as well I have two - heh,heh). Coming from an enlightened but still antidisestablishmentarianistic country, I do not view anthropomorphism based measurement units as "bad", any more than you would view a bloody axe as bad. Its just we put our faith in metal rather than flesh. I am just packing my bags for my annual pilgrimage to Sevres France to kneel before the only true Kilogram(me). Wonder what He will weigh this time?

Cheers

Steve

Oooh! Oooh! I have witnessed dimensional impurity! kilograms are mass, not force. I must now undergo the Buckingham pi sanctification ritual--dressing in sackcloth and ashes and become a mendicant eating locusts preaching to the heathen of the evils of feet and inches, gallons and units of measure not named for dead physicists.

Alas! it would have been better for me had I been caught with resumés written in English in Montreal.
