## More self-confidence for approaching games and puzzles

I've reached the proverbial straw moment where I'm realizing that, approaching any sort of numbers/critical thinking game or challenge that is meant to be fun, is instead filling me with absolute dread. I find myself becoming incredibly tense and anxious, and very often preemptively angry at myself for OF COURSE being too stupid to pick it up, which means that often I don't even try to pick it up, which then becomes an inescapable feedback loop. I need to change this, please tell me how!

## Next step: solve in three dimensions

Calculusfilter. A man is led to the center of a valuable field which he does not own. He coats his feet in blue paint so that his path can be traced. At dawn he begins walking. At a randomly selected time he will be told to stop walking, whereupon he will walk in a perfectly straight line back to the starting point. Then he will be given all the land that has been circumscribed by his blue path.

## Where's a good logic puzzle discussion forum?

I recently ran across a wonderful logic puzzle, but no solution was provided. I eventually worked out a complete solution myself, but it was rather ugly, and I would like to see if people smarter than me can come up with something more elegant. Are there any good Internet puzzle discussion forums floating around?

## It's been 24 years. I give up.

My geometry teacher in high school in 1984 showed us this puzzle. I was only half paying attention, but I believe the goal was to draw a line that intersected each segment only once.

## Help me solve this Douglas Coupland puzzle.

I am reading Douglas Coupland's new book (JPod) and I'm always a little frustrated by him. He seems to get the general vibe of nerds but is horribly off on details sometimes (in the first 50 pages, he makes reference to a "56k floppy disk"), which is agonizing. Anyway, he posits a math problem (I don't think this counts as a spoiler, I'll even omit the context and just pose the problem with page number, but if you really don't want to see anything about the book, don't read on, I guess.)

## Geometry Question

Can anyone settle a 15 year old argument for me? It turned into one of those things "we don't talk about" but it's always bugged me. The question is simple and involves three points and a circle - more inside.
