  1. Incidentally, the title was a hint too: plain in color, and also plain -->plane, since a piece of paper is flat.
  2. My intention was like this: As pure in shade as mother's blessing true, (so same color as milk) And yet in form I'm still possessing, too; (so not liquid... The other way the line could be taken would be about origami, but that was just a secondary thought) Partner both in math and drinking (math for math papers, drinking as in paper cups) I was born of man's quick thinking (because truth be told paper kinda blows my mind still)
  3. Thalia: a solid guess, but no cigar. Hint #2:
  4. Nope. Look more at the first line: what's the "mother's blessing"? I think Molly understood that.

  6. Something that should be odd, but in this case is even, which makes it a symbol of good luck. hmm...
  7. I'm very much interested. I recognize the name, too! I expect great things, my friend.
  8. Question 1: Questions 2 and 3 are correct! Followup question: What are the chances I get the health from the 14th dig versus the 15th dig? Do they differ significantly?
  9. So the other day I was watching a speedrun of the Legend of Zelda: Ocarina of Time (a speedrun is a playthrough of a game with the intent of beating the game as fast as possible). In one particular part of the game, the player is forced to follow around a gravedigger as he digs up various holes. There is one particular outcome that is desired (the "jackpot" of the game, essentially): a permanent health upgrade. There are also three undesirable outcomes that only give out money: a green rupee (the least valuable prize, pretty much $1), a blue rupee (a fairly desirable prize, say about $5), and
  10. Especially when you consider as well that at any point you've got an extra plate either to transfer to or to transfer from (although that does complicate things a bit, it also ensures that pairs such as {4,8} are solvable).
  11. But no matter what you'll always have at least one pair whose average is even. Try it: pick any three numbers such that the average of any two is odd. I'm fairly sure it's impossible, since between a+b, b+c, and a+c at least one is guaranteed to be even. Do you have another counterexample of two numbers whose average is even but can't be reached via doubling?
  12. Aw man, I was so confident I'd finally solved one of Bonanova's legendary puzzles. A start on thinking:
  13. Question: the process shown demonstrates a local maximum for the function, but is there a way to prove that (for instance) at n=1000 it doesn't suddenly reach a new maximum? (I guess what I'm trying to say is, is there a proof, or is the solution presented here just process of elimination?)
