Is this statement true or false?

[p51ngh]

Saw this the other day somewhere. Thought I would post it here.

Alright, all of you brainiacs out there. We're going to see how smart you people really are.

Is the following statement true or false?

This statement is false.

Get thinking!!

 

[debonair]

The following sentence is true. The preceding sentence is false.

Can someone help me solve this:

It is 0 degress C today and it is predicted that it will be twice as cold tomorrow. What will be the temperature tomorrow?

 

[avanbuiten]

Yes I can - tomorrow it will be -8.89 degrees C.

You're welcome!





Method:
0 degrees C = 32 Fahrenheit;
16 Fahrenheit = -8.89 degrees C

 

[p51ngh]

you have used the Farenheit scale.. why this scale? why not use the Kelvin scale or the Celcius scale?

Try solving it without converting to other scales.

 

[avanbuiten]

Ok then....the answer is -8.89 degrees C.








Method:
-2*0 degrees C = -8.89 degrees C where zero in this sense is a special number.

 

[p51ngh]

huh!?
that doesn't make any friggin sense!

OK lets say it is -8.89 degrees C today and it is predicted that it will be twice as warm tomorrow and half as warm the day after tomorrow. What will be the temperatures for the next two days?

Prove that the sum of 4 zeroes is 24.

You may use any mathematical symbol any number of times to reach the final answer of 24.

 

[4EverStudent]

How about (0! + 0! + 0! + 0!)! ?

 

[King]

24 surely..........

Regarding the temperature question.
As far as im concerned everything should be calculated in K. Not C or F.
These were made up by human beings for the craic to simplify everything.
K dosnt sound right on the weather channel.
We need everything to be relative to zero not 273.

So the answer in C should be -136.5C approx.

 

[kazikizi]

-136.5C??

it can't be...That is way too cold.

 

[jimjoachim]

Its aberdeen on a saturday night!!

Its the only logical answer.

 

[p51ngh]

Avanbiten and Jimjochim,

Lets say it is -136.5 deg C.
1. What is the temperature if it is going to be twice as warm?
2 What is the temperature if it is going to be half as warm?

I doubt if 0 deg C is going to be an answer to any of those.

 

[jimjoachim]

-136.5 C = 136.5K
Twice as warm = 273K = 0C

Keep everything in K.

 

[p51ngh]

no... you are making your calculations up. what if it is 273K and it is going to be twice as cold..... what will be the temperature?

 

[jimjoachim]

Assuming by twice as cold you mean half the heat its then 136.5K = -136.5C

If it isnt tell me why it isnt??

 

[nemesis]

Another take on the temperature question:

set a neutral temperature of 15 C (neither hot or cold) the 0 C is 15 too cold so twice as cold is -15 C.

The answer will vary depending on what temperature you define as just right.

 

[p51ngh]

Good point nemesis... actually I sort of started to think along those lines aswell:

Let TwiceCold(T Deg) denote twice the coldness of a temperature T in degrees

TwiceCold(0 Deg) cant be -136 because

1. TwiceCold(-1 Deg) is -2 deg C.
2. TwiceCold(+1 Deg) is +0.5 deg C.

1 and 2 show that twice the coldness of 0 + dT deg C is no where near -136 deg C, and that TwiceCold(0 deg C) has to be between -2 deg C and +0.5 deg C

what do you say?
