## short mind boggling questions

 Quote by dpa 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!
It's not so much art as an historical piece.

 Quote by lisab One person's boggle line is different from another's. Most PFers would find this question pretty easy, I think: 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 came up with two interesting solutions, and was working on a third at the bottom of this page that micromass might be interested in reading:

I'll post a link to the image so I don't spoil it:

You can turn around several times, so there are actually infinitely many solutions of your type (1)

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

That's why the "equator" is there. It's really just a line describing the domain of alice's house.

A short "mind boggling" problem with a "not short" answer:

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: $\frac{1}{R_{eq}} = \frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}}+...+\frac{1}{R_{n}}$ )

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.

 Quote by Ryan_m_b By what stretch of the imagination is this "art"?

It is art that is about vision enlarging and the deepening of your awareness.

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 realise 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.

Actually the art here is to make people think it's art. So it is art.

Mind boggling?
 Hello quark charmer, Is its solution related with the one with infinite row with two lines kind. Do post here. That left me thinking for a while!

 Quote by Evo Woule it be art or just a picture of a messy bedroom? I believe it would be considered the latter.
It's art, because it tells a story. The person isn't messy - she's ill. And the reason she's not present in the scene is because she has rushed to the bathroom in a hurry, seeing as how she didn't bother putting on her slippers, meaning she's probably suffering from dyssentry.

If you put this problem on a sign and hold it up in front of the building housing the Physics and Math department, how many professors will you kill off?

Or, alternatively, how many PF members will you kill off?

And something made by an artist isn't necessarily art.

It's about the emotive response, and I think that's what DPA may have been referring to in the comparison between ancient artifacts & art.

I'll take some ancient tools, smash 'em up and make some art out of it.

DPA's digital picture of "art" turned ancient artifact is equal but opposite.
