Re: 0932: "CIA"

When I learned HTML alt was both the alternative and the hover text.
In fact, I had no idea someone changed that until I read this thread.

Thx, xkcd, today I am a little bit smarter because of you.

Re: Color Switch

The above-posted general solution for the 3x3 does not actually work. (I don't know how it was supposed to work, but I tried it and it didn't.) Here's something that does (although it may, of course not be optimal): Press 2 until 2=4. Press 8 until 6=8. Press 9 until 5=6=8. Press 1 until 5=2=4. Now...

Re: Drunken sailor

I looked through the forum to find it, and I did, but I couldn't find a proof why it would work for 2 dimensions except for "Well of course it would work because it is the same thing twice" that I didn't like since I could say the same for 3 times. The thing is that an n-dimensional drunk...

Drunken sailor

Hi! I was talking to a friend about Gambler's ruin and he said that it reminded him of a puzzle he once saw here called the drunken sailor , and then he told me about the puzzle. He explained the proof that the sailor would arrive home and i thought it was really smart, but then he told me that it w...

Re: Re:

Good job on the recursion, but I do not think it is needed, in my opinion if they all know that they are all perfect logicians, and they all know that they all know they are all perfect logicians, it is enough, and the knowing descends through the hypothetical recursion. I don't think that's true. ...

Re: Re:

I think it may be worth mentioning on the page describing the puzzle itself, or somewhere else, that everyone on the island knows everyone else is a perfect logician. Hmm, yeah. Revised slightly. I'm trying to avoid making it too wordy. But what you suggest isn't technically enough -- you must also...

You ask one of them if one of the other two is younger then the third, you take the one you are told is younger of the two you didn't ask: If you asked the oldest, you marry the youngest. If you asked the youngest, you marry the oldest. If you asked the middle, you either marry the oldest or th...

Re: Poll: How many square numbers do you know?

I remember when I was visiting my Grandma, many years ago... I was six at the time. I noticed that (this is how I described it at the time): If b = a+1, then b^2 = a^2 + a + b. And so you could recursively calculate squares, and avoid multiplication. It took me a while to understand how it worked (...
