Reflecting cold

[The Natural Philosopher]

Both.

[dennis]

So the gravitational pull from the Earth on everything increases.

[Lieutenant Scott]

I've photocopied paper to make more of it. I'm telling you it works. Saves me buying my own. Let it grow its own babies!

[Lieutenant Scott]

That's just a minor English usage point, and nowhere near as silly as the other above reversals.

[Lieutenant Scott]

It's a stupid theory. The bulb would get bigger and bigger with all that darkness in it.

[Lieutenant Scott]

Is it measurable?

[Lieutenant Scott]

>>>> Dennis' physics doesn't extend to relativity.

There should be an engineers' GPS without the relativity fix, how far off would it be?

[Lieutenant Scott]

Don't, you'll get a headache.

I've never found an inaccuracy. There are scientific minds on there too, and they quickly correct any fuckups.

[Lieutenant Scott]

I'd say neither. That's POTENTIAL energy.

>>> Reflecting cold? That's an interesting concept.

Ahhhhhh, I've been fitting the reflective side inwards, how stupid of me.

Why are they called radiators when they are primarily convectors?

[Lieutenant Scott]

Which is why some people falsely believe you will freeze to death in space. More likely you will explode due to exceedingly high relative blood pressure.

[Tim Streater]

I don't think that's quite true. There will be an emission spectrum. Something red hot is emitting light, and infra-red as well. As long as the object receives as much energy as it sends out one way or another, its temperature remains constant.

[Tim Streater]

You mean its reflecting the heat radiated at it by the room, back into the room. So the wall behind it will be cooler as heat is conducted to the cold outside.

[Tim Streater]

Depends where is space you are. Equilibrium temperature at Earth's distance from the Sun is -15C. The fact that the Earth's average temperature is +15C is a bit of a clue that there is life here.

[Tim Streater]

at *all* wavelengths for which your body absorbs EMR. Water is good at absorbing infra-red.

[Tim Streater]

Mmmm, well hypothesis really. Until you make predictions based on your hypothesis and do experiments that verify that your predictions in fact occur. Then and only then do you have some right to call it a theory.

Anything that's a hypothesis.

[Tim Streater]

Now don't be silly, dennis. It *is* a theory because any number of experiments have been done to verify it. If you think it's only a hypothesis, you'll need to refute all the experiments that have confirmed it over the last 100 years.

That's perfectly possible.

Correct.

[Tim Streater]

Give them a good smack.

[Roger Chapman]

ISTR that it is roughly even stephen but can't remember whether the information relates to modern panel radiators or the old fashioned monster cast iron ones which were the original radiators.
