haha..i don't want to hear any shit from anyone about thinking spatially until you've taken a course on knot theory.

Sweet. I took a rock climbing class, we learned all sorts of knots, why they work, how they work, and when to use them.

So, I'll go on about my day thinking and discussing spatial things.

:roll:

Interestingly enough I think that's A LOT different than my #1. I'm sure there's more than one solution for a few of these... especially 1 and 10.

Aw, thanks sweetheart =)

Hmm. I guess they'd be like like most multiple variable/multiple answer problems. I'd like to see the screen shot if you still have it up?

OK - so I finally was able to find an old problem that I've already solved once, and it didnt have any ridiculous diagram to go along with it. The math is nothing more complex than high-school algebra. This is a good one for right now - as i may have to draw up some diagrams for most of the other's I can think of right off.

Given this pattern - find the exact value. yes, one exists - I already solved this one time on this forum, actually, and I've edited it - so no cheating.


1 + 1/(2+1/(1+1/(2+1/(1+1/(2 + 1.......

[HAULN-SS]

I'll post some "less numbers, more thinking" problems later tonight - more along the lines of disentanglement, walking around problems, etc.

My #1 looked like this:

ditto

And another fairly easy one for warming up with:

There's a room 10' x 38' and 20' tall. An ant is in the middle of the "short" wall, 1' off the floor - and a crumb is taped to the opposite wall 1' down from the ceiling in the middle. What is the minimal distance the ant will have to travel to get to the crumb?


I'll get the 'knot' problems up later on tonight, as i'll have to look at some diagrams and draw those, it seems.

+1... I got through it 'cause I started thinking in terms of symmetry.

The Infernal Goat
Farmer Derek has carelessly poured gasoline on his goat while refueling his tractor. Pleased with a job well done, Derek pulls out a cigarette and tosses the match over his shoulder onto the unsuspecting animal. Panicking, the flaming beast heads for a lake which is 5 miles due north of the barn. The barn is 12 miles due west of the goat. The goat runs at 25 miles per hour, but 2/3 of the way there, he falls into a ditch and breaks his leg, so his speed is reduced to 6 miles per hour, however, 1/4 the flames have been extinguished by water in the ditch. The goat can survive for one hour in complete flame. Assuming 1D6 Damage per round from fire;

Does the goat survive?
About how many hit points does the goat have, and if not enough, how many would it need to guaranteed survival?


edit: It's supposed to be 1/4 of the flames extinguished.

I got through it 'cause I started thinking in terms of symmetry.

i just realized that one block needs to satisfy all three views (3-D sudoku concept) and then saw the symmetry for some of them :lol:

[HAULN-SS]

Given 4 perfect squares of different sizes, arrange the 4 squares so that one side from each square forms the sides of an arbitrary quadrilateral. Draw lines that go from the center point of one square to the center point of the most opposite square. Repeat for the other 2 squares. Show these two overlapping lines are perpindicular.

So, in looking back at it again,

#6 can be solved with 10 blocks instead of 11.
#8 can be solved with 12 blocks instead of 16.

yea I found a few where I was 'done' but I had used less blocks than they said to use, I thought that was part of the challenge on a few of them...all in all this was pretty easy, once you skipped 1 and did the rest of them first :roll:

Math problems for fun are for the gheys.

Thats just the block building... No targets or goals.

Yeah I got excited when I realized the one I posted was a "2" but version 1 shouldn't even count.
