Solution to Chess Freeze Puzzle

Here is the solution to the Chess Freeze Puzzle published on 1st November 2007. If you havent tried it as yet.. First take a look at : Chess Freeze Puzzle
At first, the board looked almost unchanged to Norm and Ray. The most important change was that Sally had reversed the board itself; this kept Norm and Ray from noticing that the White pieces had advanced to the Black side, and vice versa. With the pawns "behind" the other pieces, and only able to move forward, things are starting to look grim. Perhaps the Knights can hop out of the jam? No, because two pawns have deftly sidestepped to block that escape route. There's no way out.

Black

N R B Q K B R N

White


Can you think of another such setup of pieces, that is substantially different from this one, and in which neither player can move or capture?

"Intellectual Genealogy Note": I really did think up this problem and its solution all by myself. However, I'm not expecting much in the way of royalties!

Alien Attack Puzzle

Alien Attack Puzzle
There are three Federation Officers assigned to take three hostile aliens to "Peace Talks" on another planet. However, they must follow the following rules:

* They have only one small space ship.
* Only two individuals can ride in the space ship each time.
* All Federation Officers can pilot the space ship, but only one alien can pilot the ship.
* If at any time there are both Federation Officers and aliens on a planet, then there must always be more (or the same number of) Federation Officers than aliens on that planet. This is because if there are more aliens than Federation Officers, then the aliens will kill the Federation Officers. Count any individual in the space ship when it is on one planet as being on that planet.
* The one space ship is the only means of transportation. There is no other way to get to the "Peace Talks". No one can exit the space ship while it is in flight.
* To start off, all the Federation Officers and aliens are on the same planet.

The Question: Can all Federation Officers and aliens get to the other planet alive, and if so: how?

Common Conversations in Human Languages

Travel across places, boundaries, countries and continents is now becoming common. English has become a connecting medium for the human race across the planet. But, how would it be to exchange pleasantries with people in their native languages. It sounds real good, to me atleast!

Check out these links:
Now, the big question: How many living human languages do exist? There are many numbers circulating around. As per the sage, there were more than 6000 human spoken languages at one time, but the effective number has now dwindled to 100, and is receding quite fast. With what is termed as Globalization, English has now emerged as the de-facto standard.

Ethnologue is an encyclopedic reference work cataloging all of the world’s 6,912 known living languages. It consists of language maps with country, language codes, language families, primary language names of 7299 languages with a total of 39,491 alternate names.

Solution to Aristotle's Number Puzzle

This is the solution to Aristotle's Number Puzzle posted on 27th October 2007. For those who haven't tried it yet, first have a look and bash your mind at Aristotle's Number Puzzle .

The other two hats have the values B = 20 and C = 30.

One stumbling block to solving this problem is the fact that, in general, you can't solve it. Or more precisely, in most case, no matter how many chances they are given, A, B and C will not be able to determine their numbers. So keep in mind that there must have been something special about the particular numbers that made it possible in this case. The fact that A was able to solve the problem is a clue as to what the numbers must have been.

Secondly, imagine that A sees that B and C both have a 25 on their hats. Since his number can't be 0 (the numbers were specified to be positive), it must be 50. And he knows this immediately. So we can rule out the case of (50,25,25).

But more importantly, we have discovered a rule. If any player sees the other two players have the same number of their hats, then that player knows immediately that his number is the sum of those numbers, and the game is over.

Now let's assume that the numbers 50, 20 and 30 are correct, and show how A figured out his number.

When A is about to make his first statement, he sees a 20 and a 30. This means his number is either 10 or 50. But he has no other information to go on, hence his statement "I cannot determine my number."

After B and C have spoken, it is A's turn again. Although B and C can't guess, this itself is an important and new piece of information for A. A now knows that there is not enough information for B or C to determine their values. And A now thinks about how this can be possible.

Remember, A knows his value is either 50 or 10. A now examines the consequences if his number is 10. In particular, he imagines the current game from C's perspective.

If A's number was 10, then when it was C's turn to speak, C would realize that his own number must be 10 or 30. But C would also know that B could not guess his own number. However, C would realize, if C's number were 10, then B would have seen two 10's and won the game. And that didn't happen.

Therefore, (still assuming that A's number is 10), and B did not see two 10's. Therefore, C would have realized that his own number cannot be 10, and so must be 30. So if A's number was 10, C would have had enough information to win the game.

But C did not say anything. Therefore, A now realizes that his own number cannot be 10, and that it must be 50. And so A can win the game.

Now, this shows that for the given data (50,20,30), A's answer is reasonable. It does not show that there is no other set of numbers for B and C for which a similar process would allow A to determine his number.

Chess Freeze Puzzle

Chess Freeze Puzzle
Norm and Ray were about to sit down to a game of chess when Sally walked in.

"Still playing the same boring game?" she asked, "Let me make it more interesting. I'll set up the pieces on the board a little differently."

"OK," they said, glad to let someone else take care of the chore of setting up the pieces. When they sat down to play, it seemed that only a few pieces were in an unusual position.

"Come on, make your move," said Norm. But when Ray picked up a piece to move, Sally said, "No, that would be illegal."

Ray's brows furrowed for a minute, and then he saw that she was right. He pondered the board for a few more minutes.

"I can't move," he said, "and what's more, neither can you."

How had Sally set up the board?
