It really does say borrow 1 sheep. Not that I didn't believe, but man. There it is.

They were practical in those days. In those days it was nothing to be ashamed of to borrow a sheep. Folks helped each other out, you know, it takes a viking to raze a village.

If I could borrow a few sheep, I wouldn't need to mow our lawn. It's not such a bad idea.

There are people up here who lend out their goats for that purpose. True.

ok - I went looking for answers elsewhere and found this ...
So in a sense, we are all right. He did and yet did not.

Semantics, not geometry - whatev.

But no one, except you, perhaps, define how to make a circle this way, where both ends are moving.

I, and some others, I daresay, define a circle (in this vernacular, vulgar example) as a closed path lying in a plane, with a center and a stationary radius. The area swept by the radius is "inside" the circle, the path traced by the other end of the radius not at the center "is" the circle and everything else beyond the distance of the radius is "outside" the circle.

Stuff inside the circle has been circled.

In your illustration, there are an infinite number of ways to get a turn of rope around the squirrel. And, yes, I can clearly see the situation you describe, and the squirrel won't be encircled. I see that. In your illustration NOTHING will have been encircled, not even the tree. Are you saying that by "attaching one end of the rope to the squirrel" that the tree escapes too?

The original question says "go around" If the earth "goes around" the moon, then why do we always see the same face of the moon? IF you "go around" the outside of your house you see the front, sides and back, becasue you went around it. If your house were to turn with you similar to the way the moon and earth turn, would you still say you went "around" your house if you didn't see the sides or the back?

Walking up and down the street isn't walking around the block.

Now, about those other answers you've all been avoiding.

this is a bit of a straw man. you would need to anchor the other end of the rope to the tree in order to be analogous to the problem at hand.

omg

But, the Earth doesn't go around the moon. The moon goes around the Earth. and if the house was rotating in place as i walked around it, always presenting the front... yes. i would still say i went around it....as long as the ground were stationary...


i know, infi... we're ridiculous.

Hey, if we configure the rope and the hunter and the squirrel and the tree like you describe, send the hunter on his path, like you describe, all that. You're saying the answer to the question "did he go around the squirrel?" is No. I ask you this question: at the end of that exercise "did he go around the tree?"

As I see it, there would be no turn of rope around the tree.

*****

If you're saying a concept of "facing" is the geometrical key here, what if the squirrel takes the rope, the hunter stands in one place holding the other end of the rope, the squirrel spins around once wrapping the rope around him, changing the "facing", the squirrel has revealed all his sides to the hunter, there's a rope encircling him, but the hunter hasn't moved. Has the hunter encircled him? Has the hunter gone around the squirrel? If it's the rope test you apply, then the answer would be yes, right?

Different question--you've shown us the booklet's "answer": "no". Is this how you, footfootfoot, would answer this question as well?

There would be no turn of rope around the tree because the rope was attached to the moving squirrel. The object of the question. If you made the tree the object of the question and attached the rope to the stationary tree there would be a turn of rope around it.

THAT is precisely the point. It is about the relative positions of the hunter and squirrel. If the squirrel stayed in one spot then the hunter would have gone around the squirrel.

I claim that the man has most positively gone around the squirrel,
just as the rim of a wheel goes around the hub which turns on the axle;
just as the earth goes around the sun, which has a lesser orbit proportional to their difference in weight.

Classic, in this case the the hub of the wheel is the tree and the squirrel is the opposite side of the rim.

MOVING RIGHT ALONG:
I'm posting two today since the first one is an old, very easy one.
