Alice leaves her house and walks north for 5 km. Then she turns and walks west for 5 km. Then she turns south and walks 5 km, and is back at her house, where she started. How is this possible?
I bet Alice's toes are frozen.lisab said:One person's boggle line is different from another's. Most PFers would find this question pretty easy, I think:

What color is the bear's fur ?

Here's an oldie I really love: You're in a room with 2 doors and 2 guards. One of the doors leads to freedom, the other to death, you don't know which is which. One of the guards always tells the truth the always lies but you don't know which guard is which.
You are allowed to ask one of the guards one question to gain your freedom. What do you ask?

well if eons later that is the only piece of digital work that survives and everything even our way of sleeping changes, then this would be one of the most valued art piece.By what stretch of the imagination is this "art"?
Woule it be art or just a picture of a messy bedroom? I believe it would be considered the latter.dpa said:well if eons later that is the only piece of digital work that survives and everything even our way of sleeping changes, then this would be one of the most valued art piece.
It's not so much art as an historical piece.dpa said:you see you consider a broken rustic chalice or ancient vase as work of art and preserve in a museum and even pay millions.
Yeah, its all about how you define art as!

Type (2) is new to me however, and pretty neat

Exactly Evo. The fact that something is a historical artefact does not automatically make it art. When I visit museums to see ancient tools it is not because I want to go and see something artistic. Even if I go to see ancient art that is far more due to historical curiosity than artistic. If someone now made a cave painting it wouldn't interest me, what interests me is the historical significance.Evo said:It's not so much art as an historical piece.

It is art that is about vision enlarging and the deepening of your awareness.Ryan_m_b said:By what stretch of the imagination is this "art"?

At first sight the artist seems to be saying to the viewer Look at This! Look at This!
But if you accept its challenge to enlarge your vision and expand your sensibilities you will realize the artist is saying Look at me! Look at me!
No, even that is too crude and reductive. M'as tu vu?! M'as tu vu?! sounds, and therefore is, better.

A short "mind boggling" problem with a "not short" answer:
http://www.mathpages.com/home/kmath668/kmath668_files/image001.gif
Infinite grid of resistors with resistance R. Find the resistance between two adjacent nodes.
I tried it for a long time, refusing to look for a solution. I finally caved though :(
(If you want to try it yourself, all you need to know is that resistors in series add up to an equivalent resistance, and resistors in parallel are equivalent by: [itex]\frac{1}{R_{eq}} = \frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}}+...+\frac{1}{R_{n}}[/itex] )

It's obvious with all the hints. Clearly, Alice lives about 5(1+1/2nPi) miles south of the North Pole ;)Q_Goest said:I bet Alice's toes are frozen.
