WRONG ANSWER!!

As long as they have matching spin state, they act as one angel
independent of their count.
My answer was "All of them". ;-)

Thanks for Playing!

No, the answer to that question is 180. Any more and they fall off
the edge.

Not to spoil anybody's fun, but the original question that the Schoolmen
were debating was whether an angel--a pure spirit--occupied any space.
The question was not whether it was 1 or 180, but whether it was a
finite or infinite number.

I AM GLAD YOU ASKED THAT. SIMPLE:
CAPS HAVE ONE BIT LESS SET, SO IT SAVES ON ENERGY.

It doesn't matter if they're set or reset. If you're perfectly
consistent, you might save kTlog(2) per character-instance, but only
when the messages are erased. So you might as well use all lower-case,
if you're really shiftless.

it "matters" more than that. lower case letters, numbers, most
punctuation and <sp> all have bit-5 (little-endian) set. the <SP> is
"important" because it exists between words. since it takes "more" power
to change states, a "significant" power savings can be had by using all
lower case.

And that's normally good enough ! Best ignore the change in boiling point vs atm
pressure. ;~)


A bit of knowledge can be dangerous...

http://www.ucl.ac.uk/sts/chang/boiling/index.htm

Which is why I reccomended condensing steam on a metal block. Avoids
all sorts of problems with superheat. Once you've done that, might as
well use the same block in melting ice for consistancy.

I JUST USED TO HOLD THE SENSOR IN MY HAND AND SET FOR 37.5°C.

Got a fever? Hands tend to be pretty cool compared to internal body
temperature, more so on some people than others.

You'd do much better by sticking it umm.. somewhere more ummm..
consistent in temperature...

Drug-store medical thermometers are very accurate within their range.
Along with melting ice, they provide an excellent pair of cal points.

A more important question is where they're keeping the
infinite number of monkeys with typewriters. Those
obviously DO exist; I submit to you, as evidence - the

An IR thermometer will not be very accurate on lower as body temps due
to the radiation measured.


An IR is good for above 50 F or 25 C
Calibration is best done close to the temps really measured.
And yes boiling and freezing water is very accurate and the method
with the black body is best.

Have I got really rubbish thermometers? I've tried measuring body temperature both in my mouth and under my arm, and it's never more than about 30C.

Anything above absolute zero emits InfraRed radiation.

IR thermometers are calibrated for a very small temperature window,
compared to the span of what is available. From low temps to high temps,
many models are available. Many operate at a specific wavelength due to
spectral windows on their transducers that make the unit very application
specific.

A good IR thermometer,correctly factory calibrated, should be left
alone, and will remain deadly accurate for years. If one thinks one's
reading is off the mark, think about emissivity factor. Do not ever
blame your instrument. Operator error is often (nearly always)the case.
Calibrated thermo-couples are always nice to have around to verify your
IR Thermometer reading capability.

That is, if one buys a reputable instrument to begin with.

Now, if you examine the spec Fluke published, you should find a range
of operation, under which it is meant to give a calibrated reading.

The device (IR Transducer) that does the reading (likely a resistor
bolometer) is perfectly capable of reading lower, but the electronics it
feeds only got designed to work in a specific voltage window, so there
will be no read out below a certain threshold. It has to do with Fluke's
circuitry and calibrated window of operation. The transducer itself is
capable of far more, I guarantee it. Just don't point it at the Sun.
