 Posts: 206 Add as FriendChallenge to a DebateSend a Message 1/10/2010 5:18:14 PMPosted: 8 years agoThis is an intersesting paradox:~From http://en.wikipedia.org...'s_paradox_of_the_Grand_HotelConsider a hypothetical hotel with many rooms, all of which are occupied – that is to say every room contains a guest. Suppose a new guest arrives and wishes to be accommodated in the hotel. If the hotel had only finitely many rooms, then it can be clearly seen that the request could not be fulfilled. But the hotel of interest has infinitely many rooms, so if you move the guest occupying room 1 to room 2, the guest occupying room 2 to room 3 and so on, you can fit the newcomer into room 1. By repeating this procedure, it is possible to make room for a countably infinite number of new clients: just move the person occupying room 1 to room 2, the guest occupying room 2 to room 4, and in general room N to room 2N, and all the odd-numbered rooms will be free for the new guests.--Thoughts?After demonstrating his existence with complete certainty with the proposition "I think, therefore I am", Descartes walks into a bar, sitting next to a gorgeous priest. The priest asks Descartes, "Would you like a drink?" Descartes responds, "I think not," and then proceeds to vanish in a puff of illogic.

Then again I'm biased. (^_^)At 10/3/2016 11:49:13 PM, thett3 wrote: BLACK LIVES MATTER!

This is because infinities are unbounded, and they follow different mathematical rules than finite numbers.For instance, if you take an infinite value and add 1 to it, the value has not changed at all. You can continue to do this ad infinitum and the value has not changed.So even though you have added more guests and not gotten rid of any, the number of guests in the hotel has remained exactly the same. This would not have been true in the case of a finite hotel, which is why it is not possible in that case. However, infinity functions in a way so that there is no contradiction.

You can't divide infinity by infinity, and you can't fill infinity with infinity. Infinity is not finite, it's not a number.-- I agree that it is true that its not number. Which just brought to my attention that the enire paradox assumes it is a number when it says, "infinite number of rooms".-- The reason that it is a paradox is because it contains a contradiction which was logicaly (maybe) derived from "true" premises.I fail to see the contradiction.-- A contradiction exists if we accept that in this case it is possible to add to an already full hotel.

If you truly have an infinite number of rooms, and the guests are arriving at a finite rate (as the story implies), there will always be more room. Sure, you could say that an infinite number of rooms minus an infinite number of guests means no rooms, but infinity minus one is still infinity, and minus another one is infinity, and infinity minus one ad infinitum will remain infinity.

Essentially, you constantly double the number of guests. Infinity will NEVER be reached, and therefore, the rooms will never run out.

I'm pretty sure the hotel starts with infinite guests in this example, though.

 Posts: 3,500 Add as FriendChallenge to a DebateSend a Message 1/11/2010 6:45:57 PMPosted: 8 years agoThe problem is the premise that you've filled a hotel with infinite rooms. If this is true, then you can't add more people.It is odd when one's capacity for compassion is measured not in what he is willing to do by his own time, effort, and property, but what he will force others to do with their own property instead.

 Posts: 751 Add as FriendChallenge to a DebateSend a Message 1/12/2010 5:13:39 AMPosted: 8 years agoConsider a hypothetical hotel with many rooms, all of which are occupied Then by definition the hotel must have a finite number of rooms.But the hotel of interest has infinitely many roomsIf the hotel had "infinitely" many rooms, then there are an infinite number of empty rooms at all times, no matter how many guest you have (even if that number was infinite!). Why?Well vacancies = number of rooms - number of occupantsObviously infinity - any real number = infinity... so that case is trivial.But what if you had infinite occupants? Does infinity - infinity = 0? No.Lets assume:infinity - infinity = 0But now lets add one to each side: 1 + infinity - infinity = 0 + 1. Well we know infinity + 1 = infinity so what we now have is:infinity - infinity = 1Oops! It turns out infinity - infinty is undefined because infinity is just a conceptual limit and not an actually defined term.So the "paradox" is really just a misuse of mathematical terms to create a bogus premise.
