(Solution to Problem 56)IHearYou2 gives the correct solution in #817, although no explanation. ![:(](//storage.proboards.com/forum/images/smiley/sad.png) The greatest time an EEer can stay on the plank is one hour (corresponding to a distance of one mile). Think of the EEers as silhouettes. Two EEers bumping into each other and instantly turning around looks exactly the same as two EEers passing "through" each other. So even though EEers are constantly bumping, to an observer there is simply one group of silhouettes marching right at 1 mph and one group marching left at 1 mph and the two groups just pass straight through each other. With this in mind, it is easy to see that placing a right-facing EEer on the left edge of the plank and/or placing a left-facing EEer on the right edge of the plank is the best we can do. In either case, regardless of how other EEers are laid out, at least one EEer walks a full mile along the plank.

Problem 57 (Grand Relocation Problem) - Alien Attack!The following puzzle is also one of the more interesting (and less taxing) ones from the 2010 CPC, this one by Mr. Clyde Law. To complete it, I recommend either: - right clicking, copying the image, and pasting it into MS Paint, where you can easily complete it using the flood filler
- right clicking, viewing the image, and printing it
NO visiting the 2010 CPC site to find the solution! Such actions are cheating. ![](http://boards.msn.com/Themes/default/emoticons/angry_smile.gif) ![](http://img90.imageshack.us/img90/8836/fillo1.gif) ![](http://img824.imageshack.us/img824/2406/fillomino.gif) ![](http://img838.imageshack.us/img838/8155/fillo2.gif) The first to complete it earns the distinction "Temporary Saviour of Earth". ![](http://boards.msn.com/Themes/default/emoticons/thumbs_up.gif)

FLUORIDE IS THE TRUTH! *Tsk* Poor deluded SbS... treating the verb "is" as set equivalence rather than (the correct) set inclusion. In fluoride land, if SbS is a person and a nutty person is a person, we must conclude that SbS is a nutty person. Shameful that our friend was driven to such an admission: ![:(](//storage.proboards.com/forum/images/smiley/sad.png) (It's in bold, caps, glowing and in blue, so it MUST be true.) ;D So that's how they got you environmental engineers around moral hazard! The CDC made their videos blue and glowy! ![:o](//storage.proboards.com/forum/images/smiley/shocked.png)

Ha! Quick! The solution to the puzzle is not the completed fillominos. It's the words spelled out by the special (red) fillominos. Somebody pull it out of SbS's image quick and help her snatch defeat from the jaws of victory! ![:D](//storage.proboards.com/forum/images/smiley/grin.png)

Contributor Puzzle - Frog Leap TestBy: kentThis might drive you crazy! Keep at it 'cause it is possible. This is one way to keep your mind sharp! Here is a little 'test' that is (supposedly) part of a second grade Computer class in China. Some figure it out right away. Others report having to work on it for a week (or more) to solve it.

Problem 58 - The Ping Pong Puzzler
You are in a room that is a perfect 8 x 8 x 8 cube. There are no windows or doors (don't ask me how you got in there). In the center of the floor there is a 12 inch pipe that is sticking 6 inches out of the floor. In the bottom of the pipe is a ping pong ball with a diameter that is one millimeter smaller than the inner diameter of the pipe.
You have a 12 inch piece of string, a match, a magnifying glass, a 6" ruler and a paper clip.
How do you get the ping pong ball out of the hole?
(Note: the answer to this one can be Googled but it wholly takes the fun out of it. I'm curious to find out if the EE crowd can think "out of the box" enough to solve it sans Google.)

Lay the ruler across the top of the pipe, tie one end of the string to the ruler, the other to the paperclip. lower the paperclip onto the top of the ping-pong ball, light the match, and use the magnifying glass to focus the light onto the paperclip until it is just hot enough that part of the ping pong ball melts to it and then you can lift it out. Obviously I didn't use google, and it probably wouldn't work (can't keep a match let long enough) but, that's the first thing off the top of my head.

I was about to type my 'solution' when yours appeared, Apple. The concept was similar except for when to heat the paperclip: Tie one end of string around center of ruler, and the other end around paper clip. Balance ruler over pipe opening. Before lowering paper clip, unbend the loose end, and heat the tip using magnifying glass and match. Quickly lower paperclip down to fuse it to the ping-pong ball, and then raise the string to remove ball.

Problem 59 - Canada's Odd DemographicsCanada is full of Canadians--about 33 million of them at present. What you may not have known is that all Canadians are the same age. Don't believe me? I'll prove it to you. Suppose there are exactly n people in Canada, where n is a whole number. My proof is simple enough: we assume that any subset of n-1 Canadians are all identical in age, and prove that the full set of n Canadians are identical in age. To do this: choose an (arbitrary) set of n-1 Canadians. Call the set 'A', and pick two (arbitrary) Canadians in it. Call them c1 and c2. Now choose a second, different set of n-1 Canadians. Call this set 'B'. Since set A can only have one Canadian that set B does not, we know that either i) c1 must be in both A and B, ii) c2 must be in both A and B, or iii) c1 and c2 are both in A and B. Hence, there is always one Canadian in both sets. Let us call this Canadian 'c'. We know that everyone in set A (by assumption) has the same age. Hence, c's age is group A's age. We also know that everyone in set B has the same age. Hence, c's age is group B's age. Hence, set A's age and set B's age are equal. And since everyone in our complete set of n is contained in either A or B, we conclude that everyone in the complete set has the same age. So, we've proved that if any n-1 Canadians have the same age then any n Canadians have the same age. Naturally, we can extend by induction backwards from n = 33 million all the way to n = 1. Start by assuming that every 32,999,999 Canadians have the same age, and use our proof to show that all 33,000,000 Canadians are the same age. To prove that every 32,999,999 Canadians have the same age, we assume that every 32,999,998 Canadians have the same age and use our proof again, etc., etc., all the way back to n = 1. For n = 1, a set of one Canadian is just one person. Hence, trivially we see that everyone in the set has the same age. Therefore we have proved by induction that every Canadian is the same age! ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) Now... you might be thinking: that's some wacky math. But the brainteaser is: where is the fallacy in my logic? Where is the error?

(SPOILER)
If n=2 how can there be one Canadian in both sets?
(Highlight the text in this message to reveal.)
Is it true that the average Canadian has one breast and one testicle?

Problem 60 - Literally a Problem
The words below will all look familiar. But many of us use them in such specific contexts that we lose track of their deeper literal meaning. For example: "candidate A was on par with the other candidates" borrows the word 'par' from golf, where 'par' literally refers to the expected number of strokes a professional player should take on a particular hole. Without using a search engine, a dictionary, or any other resource, can you provide the literal meanings of the following words (or at least your best guess)? Please indicate '(SPOILER)' if your post contains solutions. Or if you know how, enclose your solution in a [color=white] [/color] block as colleenz has done in #227. I will award 1 karma to each poster who contributes at least one correct answer (or a suitably humorous "best guess" ![;)](//storage.proboards.com/forum/images/smiley/wink.png) ). 1. blasted (adj.), e.g. "I'm going to kill that blasted snow leopard." 2. enormity (n.), e.g. "The enormity of the Tartans' victory finally dawned on him." 3. SWAT (n.), e.g. "The SWAT team stormed into SBS's villa to shut down her illegal fluoride operation." 4. sin (n.), e.g. "Arnold Schwarzenegger's sin had come back to haunt him." 5. moron (n.), e.g. "Fund snow leopard conservation? You must think I'm some kind of moron." 6. chesterfield (n.), e.g. "After successfully slaying the snow leopard, I collapsed in my comfy chesterfield." 7. yuppie (n.), e.g. "I applied for the job but they hired some yuppie." 8. layman (n.), e.g. "Don't ask me. I consider myself a layman in these matters." 9. draconian (adj.), e.g. "I consider myself tough on crime and even I thought the treatment was draconian." ( Hint: the literal definition has nothing to do with dragons.) 10. lambaste (v.), e.g. "I'm watching the politicians lambaste each other on C-SPAN." ( Bonus: one karma to you if you can give the literal meaning of "C-SPAN" sans help.) BONUS: hell (n.) - In this case, I'm looking for original definition in Old English. +1 karma to the person who solves it sans help.

Problem 61 - Logical and Not
For the logical at heart: You are a cook in a remote area with no clocks or other way of keeping time other than a four minute sandglass timer and a seven minute sandglass timer. (The kind you turn over - hourglass shaped.) You do have a stove, however, with water in a pot already boiling. Somebody asks you for a nine-minute egg, and you know this person is a perfectionist and will be able to tell if you undercook or overcook the eggs by even a few seconds. What is the least amount of time it will take to prepare the egg? And how will you prepare it so that it is neither undercooked or overcooked? For the not-so-logical at heart: A completely black dog is strolling down Main Street during a total blackout affecting the entire town. Not a single streetlight has been on for hours. Just as the dog is crossing the middle line, a Buick Skylark with 2 broken headlights speedily approaches his position but manages to swerve out of the way just in time. How could the driver have possibly seen the dog to swerve in time? (Please remember to prefix hints with '[HINT]' and spoilers (solutions) with ' '.)
