G> front of a door. You are
G> given a task: pick a door and go through it. One of the doors leads to
G> heaven, the other leads to hell. You are allowed to ask
G> ONE question to one
G> guard to help you decide. However, one guard will always tell the truth,
G> while the other must always tell a lie. Both guards know which is the
good
G> door...

Confession: I kind of cheated here, got the idea from that other chap who
replied first, but couldn't finish his sentences.

Something like "Would you say yes if I asked you if you were guarding the
door to hevean?".

The hevean guard would have to say "yes" and the hell guy "no".

This sort of looks like two questions rolled into one, does that count? I
guess since there's only one yes/no answer it must, right?

Another way to tell could be that the guard telling the truth would know
the answer straight away as it would just be like one question to him, the
liar might get confused a bit.

Heeey, cool. That seems to work OK in my mind at least.

XLNC's answer is close to the 'traditional' way of solving the puzzle. Ask
the question "Which door would the OTHER guard tell me to go through to get
to heaven". Which ever door you are told, go through the other one. This
involves too many double negatives for me, but if you get a piece of paper
out and try it, it works Smile

My solution was to ask "Is the liar guarding the door to heaven?". If the
guard you ask answers 'yes' then go through the other door. If he answers
'no' go through that door. This actually works with any combination of
liar/honest and heaven/hell. How you ask the question determines whether you
go through the 'yes' door or the 'no' door. Try it on paper.

Cool, that looks like three ways of solving the problem. Anyone got any more
by any chance?

More things to warp the mind. A cool puzzle I found in a book called
'riddles in mathematics' or summat like that.


Three guys go into a restaurant. After the meal the waiter brings them the
tab - $30. Each guy gives $10 to the waiter, who takes the money out back to
the manager of the restaurant. When the waiter meets the manager, the
manager says there's been a mistake in the billing - the total cost of the
meal was only $25. The waiter is given the $5 difference to return to the
customers.

On his way back, the waiter realises that $5 will be hard to split between
three people. He pockets $2, figuring that noone will ever know, and returns
$1 to each of the customers.

Now each person payed $9 for the meal, 9x3 = 27. The waiter has $2 in his
pocket. 27 + 2 = 29. But $30 was originally payed. Where did that last
dollar go? Smile

Well let's see, they payed $27, they should have payed $25, the waiter kept
the $2 difference, where's the problem?

I don't think I understand the answer, but putting it like that makes it
seem to work. Smile

Ah, you're too good for me Smile You're right. The hangup which seems to
occur for most people (myself included) is caused not by the story, but by
the wording of the question. The question makes out that you've somehow got
to combine 3 lots of $9 and $2 to make the original $30. Of course this is a
load of bollox. You got it right in that its not $30 you're aiming for...
its the $25 cost of the meal. That one took me, and others I've told the
problem to, a while to figure out.

There's a good story in my favourite book about hangups like this. The
book is going on about how your mind can get set on viewing a problem from
one angle, and fail to see a solution because the problem is only viewed
from a flawed perspective. This is the problem I had with the above puzzle,
when I spent quite some time trying to get $30. $30 has nothing to do with
it.

Anyway. The story is about catching monkeys. Apparently true. Villagers
put a post in the ground and tie a rope to it. The other end of the rope is
attached to a coconut which has been hollowed out; the coconut has a small
hole in it... large enough for a monkey to reach inside. The coconut is part
filled with rice. The monkey comes along, and is able to work out that it
can take the rice by reaching inside. But once it's hand is closed full of
rice, the hand cannot fit back through the hole. As the villagers rush
toward the monkey, its brain is incapable of realising that he can get away
if only he lets go of the rice. The monkey is trapped by its own mindset.

Bugger.

Here's something that's been bugging me for a while now...

Plants and trees.

I'm sure the bastards know things that they're not letting on...

For instance:   How does the sap go all the way to the top and back?  They don't have hearts, and from what I can see from felled tree stumps, they don't have veins either, but there must be some pressure there, otherwise the sap wouldn't run out when you cut them.  People have said things about the pressure from the leaves and the sun and warble grumph, but the things don't die when they lose their leaves in Autumn, and the tree doesn't die in zero degree temperatures.  My Dad doesn't have the answer either, and he said it bugs him too... as he read an article saying that with gravity a tree can only logically have sap up to a certain height, but they can grow higher than that.

Also:  when you have trees growing in a clump, they seem to know that there's another tree next to them and don't grow their limbs long enough to encroach on their space.  How do they know?

How do they all know when to flower at the same time?  How did they know what sort of flower system to create to get specific pollinators? (God I love spellcheck!)

How can they suck up water?  Why, if they're like Spider plants which forms offshoots of little plants which fall down and create new ones, do they need to flower?

Bloody things annoy me.
