Difficult question

[fruitfly]

If the outside temperature is 0 C and by the time we get back it will be twice as cold, what will be the temperature?


This is a very important thing to know when making a flightplan, so I guess it shouldn't be too difficult for our real-world pilots!

Just answered the first thing that came to my mind...

Twice as cold? 0C is 32F, so would it be 16F? You really can't multiply/divide with 0.

[fruitfly]

That's right! It has to be transposed to some other system; 0 is not a number, but a sign for nothing.

I hoped it will take you longer! Maybe I'll have more luck with this one:

Why did the kamikaze wear helmets?

Because injuring your head if forced to do some maneuvers enroute and crashing the plane into the ocean would've been even more pointless than
reaching your destination and killing yourself by hitting the target.

You are all so serious !!!

Ah but Engineers and Mathematicians regard 0 as a real number.

fruitfly: Sorry, but your question made me think and that was the result.

No one here is quite that nerdy! JK!

Twice as cold?

I don't think it's a question of numbers, but a question of feel. When does it feel twice as cold or twice as hot.\

It would vary from person to person me thinks.

[pegase]

In fact, twice as cold is an oximoron.

The absolute 0 is like in space -272° C
So let's return Fruitfly's question like this:


what will be the temperature when it will be HALF AS WARM

Things become eazy: -136°

[AndrePaul]

as brad said 0 is 32F, so half wud be 16F, so i am guessing -2????????

You pose a very interesting question. What is the temperature if it's
twice as cold as zero degrees? The Fahrenheit and Celsius temperature
scales are "relative" temperature scales, in that they are both
relative to a couple of specific temperatures, namely the freezing and
boiling points of water.

Let's make your question a little more specific: "What is the
temperature if it's twice as warm as 0 degrees Celsius (the freezing
point of water)?" To answer this question we need to convert this
Celsius temperature to an "absolute" temperature scale, a scale with
no negative temperatures. We'll use the Kelvin scale.

0 degrees Kelvin is the point at which all motion in matter stops; it
is known as "absolute zero." No temperature can exist that is lower
than 0 degrees Kelvin. The formula to convert from Celsius to Kelvin
temperature is K = C + 273.15, where K is the Kelvin temperature and C
is the Celsius temperature. So 0 degrees Celsius is equal to 273.15
degrees Kelvin. We can double this number to get 546.30, the
temperature that is twice as warm as 0 degrees Celsius. We can then
subtract 273.15 from our answer to convert it back to the Celsius
scale.

The temperature is 273.15 degrees Celsius when it is twice as warm as
0 degrees Celsius.

Makes perfect sense, doesn't it?

HAAAAAAAAAAAA! GREAT! I love it! THAT's the answer. It's gotta be!



And if you like the tricks with numbers, listen to this one. It's an ancient one. Originaly it was about camels, but since this is an FS forum, I'll
adapt it a bit. So it goes:

Once upon a time there was a man who was working hard all his life and at the eve of his life he had an airline company consisted of 17
planes. (We'll have to assume they were the same brand!)
But that was not all he had; he also had three sons: the oldest, not so old and the youngest.
As it sometimes happens, he felt he was parting with life, so he summoned his sons and at his death bed he told them:
"My dear sons, it's time for me to go where every living thing goes. I have acomplished many things, but what really matters is this
company. Don't reduce it; don't sell the planes once I'm gone. I leave it all to you and the way you will divide it amongst yourselves will be
this way:

The oldest one, you will inherit 1/2 of the planes!
Not so old one, you'll get 1/3 of the planes!
The youngest one will get 1/9 of the planes!

As he had said that, he passed away.

The brothers knew right away it will be impossible to fulfill the father's wish without selling a plane. And yet, they have promissed not to do
so. They also knew their father was not senile and he knew what he was talking about very well. They tryed everything, but in vain.
So they decided to call for help.
They knew there was a wise man in a distant country so they sent him a mail:
"We need your help urgently! We'll send you a plane to pick you up, just say when and where."
He promptly replyed:
"I accept the invitation. No need to send a plane for me - I'll come with my own. But you will pay me 100 000 $."

OK!

So to make a long story short, he came, solved the problem, took the money and flew back home.

How did he do that!?

(Dan, maybe we should have psted this as an easter egg question!? )



P.S. The answer is VERY ELEGANT!!!

Half as warm for zero would be the same as half as cold - the answer will always be zero.
