Cheap thermometer calibration technique?

Correct. It's also not good for tea too.

Ever heard of "the Curate's egg" ?

As Rich pointed out earlier, boiling occurs when the vapour pressure equals the ambient pressure. The reason is that at that point there's nothing to prevent bubbles from growing without limit. You do need to nucleate the bubbles first, of course, which is why still liquids can be superheated considerably before they launch.

Isn't it always ? The things I've seen people do !

atm

Sure, but my method works in the office kitchen with an electric kettle. Note that the temp drops a couple of degrees when power is removed, indicating that the liberated steam is (briefly) over 100C.

Graham

But there are hot and cold people by at least a degree either way.

Graham

p.s. I thought it was 37.4 anyway.

The way the French do ? Wonder what they do in Quebec !

Graham

Could this possibly be the funniest and most arcane thread to appear in s.e.d for a long long time ?

Graham

Nah. Or at least, not just that. Pull (and hold) sufficient vacuum on a container with water in it, and the water will indeed boil away at low temperature. Granted, you'll get any dissolved air out of it during the process, but that'll only be part of what goes on.

Not here. I have a CRT display and read news in white-on-black. Caps have more pixels set, therefore more illuminated CRT pixels so more energy used.

Bye.

Ouch ! That must hurt !

Graham

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.

Yes... less caloric input to the egg per unit time.

He is an idiot. The excess air comes out of water LONG before it ever reaches a vacuum.

It changes phase, DonkTard. Lay terms... that's boiling, idiot, which it physically does quite violently, until it is all vaporized, and removed from the chamber (most of it).

Is it all black or all white that uses more power on a CRT?

LCD? Plasma?

Subtractive or additive color mixing?

On a CRT the illuminated pixels come from (multiple) electrons sent from the back end of the tube at high speed, dark pixels are where no electrons are flowing.

LCDs use a kind of optical gate to control the flow of light, dark pixels and light pixels cost pretty-much the same amount, most of the energy is used to run the backlight.

these are like a bunch of tiny neon lamps, they light up when a current is flowing, dark pixels use less power.

LED displays are like that too.

Until the dark emitting diode is prefected all luminescent displays will be additive :)

It doesn't. Everybody's known that since fourth grade, except the incurable idiots.

Thanks, Rich

In article ,=20 snipped-for-privacy@yeeha.com says...>=20

it "matters" more than that. lower case letters, numbers, most=20 punctuation and all have bit-5 (little-endian) set. the =20 is "important" because it exists between words. since it takes=20 "more" power to change states, a "significant" power savings can be=20 had by using all lower case.
