that's a low-frequency ee forumula, with f = 0.000012 hz :-)
the 400 btu/h-f car conductance might be a 10'x20'x4' box with poor
insulation... 16 ft^3 of steel might have 1000 btu/f, like the same
volume of water.

one master's thesis explored the optimal number of ice cubes for a drink.
the last speck of ice should melt when the drink is done. too few cubes
leave the drink warm, and too many waste ice and reduce the drink volume.
after lots of experimentation, the answer was between 2 and 3.
what are the dimensions of the margarita glass? three 5 f cubes (59 grams,
with 59/454(0.5(32-5)+144) = 20 btu of cooling) seem to work well for
1 liter of 44 f water in two batches in an 8 cm id x 14 cm tall mug
with a 0.5 cm wall thickness and no lid.

obfrug: iraq is not frugal. just started reading webster griffin tarpley's
510-page "9/11 synthetic terror--made in usa." the preface concludes:
it was clearly essential that measures be taken to keep the fingers
of bush, cheney, and the increasingly desperate neocon fascist madmen
away from the nuclear button. during watergate, when nixon had called
his infamous 1973 worldwide nuclear alert as a result of the october
1973 middle east war, british prime minister ted heath had seen the
entire stunt as a manufactured diversion from nixon's watergate troubles
at home. as the bush administration disintegrates, it is clear that
conditions today are similar. on october 28, 2005, when special counsel
fitzgerald presented his indictment of the neocon fanatic irv lewis libby,
bush simultaneously made a raving speech branding iran and syria as
outlaw states with whom his patience was exhausted. many cable networks
showed fitzgerald and bush, along with cheney, as parts of the same
split screen. there it was: wag the dog, in real time. kissinger and haig,
sociopaths though they were, had taken measures to supervise nixon's
access to the football, the briefcase containing the nuclear launch
codes. in the last weeks of watergate, defense secretary schlesinger
had issued a standing order to combat commanders telling them to ignore
any and all orders by nixon to launch attacks unless and until they were
confirmed by himself or by kissinger. in today's white house, there are
no figures to look to who might impose similar restraint: quite the
contrary. faced with looming indictments of many of their clique,
the neocons tended towards a mood of goetterdaemmerung and apocalypse.
the neocons would doubtless prefer a new world war to life behind bars;
like the ss in berlin during the last days, they would think nothing
of letting the river water into the subway tunnels where their
insufficiently martial fellow citizens were hiding.
the impeachment of bush and of many others could hardly wait until 2007.
gunpowder day, november 5, 2005.
