Logic Problem, Can you solve it?
I know this is really nerdy, but I felt compelled to post it anyways!
(I know you've probably heard it, though. It's quite old.) If it's zero degrees fahrenheit today, and it is going to be twice as cold tomorrow, then what is the temperature, in fahrenheit, going to be tomorrow? I came up with a solution of my own, but it's only half-feasible! |

The coldest that you can go is absolute zero, or -459 F.
So, if it were -229.5 F (half of -459) and someone said it was going to be twice as warm you would say -229.5 F + 229.5 F = 0 F. So I say that twice as cold as 0 F is -229.5 F. That's my final answer. |

The statement "twice as cold" makes the problem impossible to solve. "Cold" is simply an absence of heat in varying degrees (from 0 degrees Kelvin to infinity degrees Kelving), meaning that "twice as cold" is a value relative to "warm" or "hot". No reference to "warm" or "hot" was given, thus the problem is mathematically impossible to solve.
Trying to divide 0 degrees or a conversion of 0 to another scale is also inaccurate, as "dividing by two" or "halfing" was not called for: converting to Kelvin and dividing the result by two is not a true solution, as to divide "cold" by two, you must first define it relative to "warm", and as discussed in the previous paragraph, that is impossible you are all wrong |

you implied that it is 0f "warm" or "hot" by giving that temperature |

^^^ this is the right logic. i did not do the calculations so i'm not sure about the number Slik provided. but if you follow this, then you should get the right answer. makes sense to me. |
