The physicist Dirac once gave a lecture at the end of which, he said : " Are there any questions?" One student raised his hand and said: " Professor Dirac, I didn't understand your proof of Theorem 3." Professor Dirac replied : " That's not a question! "

So far, our lovely pianolady has been kind enough to post my jokes and puzzles for me, because I was not quite sure how to do it, but now I think I do, hence from now on, I will post them myself. My deepest thanks to Monica!

A 2volume set of books is sitting on a shelf. Volume 1 has 256 pages and Volume 2 has 257 pages. A bookworm starts from the first page of Volume 1 and bores its wat to the last page of Volume 2. The thickness of the pages of each volme is two inches, and each cover is one quarter of an inch thick.How far did the worm fravel?
NOTE: Whenever I end with a question, the answer will be given next time.

Raymond  I think you just made a kind of paradox/riddle right here. "How can one member post a message but it shows up as being from another member?"
FYI you other guys  I was doing the posting for Raymond, including the last one, which is why it's from pianolady and not Raymond.
my guess  the worm traveled 4 1/2 inches?

My english is probably not good enough for the details. If the complete cover of a single book is 1/4 inch, then the front side or back side of the cover is each 1/8 inch, provided the thickness is equally distributed.
Then the worm goes through 2*2 inches (paper way) and 2*1/8 cover ways, that means 4 1/4 inches all together?
But maybe Raymond will have it more precisely. The first book has 256 pages, and the second book has 257 pages. I assume the worm starts inclusively the first page of the first book, and reaches the last page of the second book (but eats not through the last page, very, very important!).
So more precisely I would say, the way is 2 inches + 1/4 inch + 2*256/257inches, what means alltogether NEARLY 4.242217899 inches

Assuming that Volume 1 is on the left and Volume 2 is on the right and that the books are arranged in a traditional bookshelf manner, it would be .5 inches. If Volume 1 is on the right and Volume 2 is on the left and the books are arranged in a traditional bookshelf manner, then it would be 4.5 inches. I'm not sure why you included the number of pages, though. Unless it was in an attempt to make the trick of the riddle as plain as possible without giving it away...

Oh yeah [hitting myself on the head]. Good one!
Should have known it would have been trickier than what I first thought.

Yes, riddles are never that simple, though this one was pretty simple as far as riddles go. Though I think Ray should have worded it a bit better.

Great
Ok, Terez gets a point. But Olaf should get something for his answer  like a handshake, or .0001 point because although incorrect, it sounded good.

It wasn't incorrect, really, any more than your answer was. Because if Volume 1 were on the right, you would be correct, and Olaf would also be correct if at the same time a bit nitpicky.

For the bookworm problem, I am assuming that the books are in the normal position, in which Volume 1 is to the left of Volume 2, in which case the 1st page of Volume 1 is separated from the last page of Volume 2 only by two book covers! And so the answer is one half an inch (as some of you have already realized), not 4.5 inches, which is the usual answer. But as Terez correctly pointed out , if Vol. 1 were to the right of Vol. 2, then the answer would be 4.5 inches. Terez was also right in that in the statement of the problem, I should have said that the two volumes were in the normal position in that Vol.1 was to the left of Vol.2.
Here is another one, perhaps too simple: A certain draw contains 24 blue socks and 24 red socks .Someone goes into the room where the draw is, but the room is dark. What is the minimum number of socks she must take out of the draw to be sure that she has two socks of the same color? [Answer given next time.]

uhhh... would the answer be 3 socks? Because if you draw the first, it's either red or blue... then the second could be the same as the first, or different. Then the 3rd would automatically match one of the two picked originally.
Oh... and Nihilists don't believe in absolute zero, because they believe the universe has no absolute constants!

In most people's closets, the socks are organized in pairs or it would be a hell every morning to find a matching pair right? In that case, it would be sufficient to only take out one pair (assuming again that the organizer of the closet pair them in colors from the beginning), so to speak two socks.
However, I believe that we should not involve people's habits in the riddle, so the answer is already given by demonic_advent namely 3 socks.
(...and what is a Nihilists? It is not in any of my lexicons...)
Along with demonic and Robert and three socks  'I concur'. (I've always wanted to say that )

Nihilism
the belief that there is no universal truth or underlying reality that undergirds moral values; that ultimately existence is meaningless. From the Latin "nihil" or "nothing".

Madam, what makes you think that I play with my hands?

As some of you have coreectly said,the answer to the problem of the 24 blue and 24 red socks is 3, not 25! Since there are not 3 different colors, then given 3 socks, at least two of them must be of the same color.
If I had asked what is the smallest number of socks one must draw to be sure of getting at least two of DIFFERENT colors, then the answer would be 25.
I am reminded of a joke: A man meets a friend on the street and says: "Do you realize that you are wearing one black shoe and one brown shoe?' The friend replies;' That's interesting. I have another pair just like it at home."
Now for another puzzle: A certain convention hosted 100 politicians. Some were honest and some were crooked. A statistician observed that whichever two were picked at random, at least one of them was crooked. From this, can it be determined exactly how many are honest and how many are crooked? [Answer next time.]

The most obvious answer would be that 99 were crooked and 1 was honest as if it was 100% certain that whatever pair he picked, at least one was crooked there could not be more than 1 honest. If there were two honest, they could be picked at the same time.
What I don't like about my answer is how you put it when you say "some were honest". Were indicates plural which means that there should be more than 1. However, I am not sure we should involve grammar in the riddles.
By the way, I would not like to live in that country...possible I might already do .

It can't be determined... because if we only know that one of the two is crooked, then we don't know what the other is. He could be either. Thus, it's impossible to find an exact number.

Well Robert, your problem is only HYPOTHETICALLY solvable since the very premise of there being an honest politician must also be assumed to be hypothetical. So, hypothetically speaking the answer is that there is exactly one hypothetically honest politician in the group. If there were more
than one, then a pair could be formed that did NOT have a crooked politician, hypothetically speaking of course.
By the way, not hypothetically speaking I thoroughly enjoyed your Bach on youtube.

I'm confused. Raymond  has this been solved already?

But can a hypothetical answer be correct?
The way I would look at it is like this: The original phrasing in the question was could it be determined how many were crooked. TECHNICALLY... ignoring any hypotheticals... it CANNOT be determined, because there if you pick out two, and at least one is crooked... then technically speaking, there could be as little as 1 honest man, but possibly more. Technically... it's impossible to determine an exact amount. There can be any number of hypothetical numbers... but can hypotheticals really work?
God... I'm sooooo confused...

But how can it be 1 honest and 99 crooked???
... life just doesn't make sense.
My brain is already fried enough from having my midterm exams this week... and I just got demolished by my Astronomy and British Literature midterms... I can't even imagine trying to figure out how this riddle is possible.
... I'm off to go hide in the corner again

I think it is high time that the polition puzzle gets settled! Some of you have already gotten it correctly: We are givn that of the hundred politicians, some were honest and some were crooked, hence there is at least one honest one call him Jim. Now pair Jim with any one of the other 99 politionsin this pair, at least one is crooked (which is given), but it isn't Jim, so it must be the other one. This "other one" can be ANY of the 99. hence all of these 99 are crooked!
Put more simply, to say that of any two, at least one is crooked, is but another way of saying that no two are honest, and hence at most one is honestor still put otherwise, if two were honest, those two would form a pair in which neither was crooked, violating the given condition that there is no such pair.
Another puzzle: A boat has a metal ladder coming over the side with six rungs spaced one foot apart. At low tide the water hit the second rung from the bottom. Then the water rose two feet. Which rung did it then hit?

oh, yay  I know this one. (Raymond, thanks for posting this when I'm awake).
When the water rises, so does the boat. Hence, the water level stays the same on the ladder= the second rung from the bottom.
Robert  I gave up on the river quiz, and I can't find my reading glasses to see the answer.

Now now Pianolady....just becareful, haven't you learned a lesson with Smullyan's puzzles? Those who are hasty with answering are usually wrong (or dead lucky).
With a puzzle the first thing to do is ask a question:
The puzzle states that the ladder is coming over the boat, that does not necessarily imply that it originates from the boat. The ladder could be driven into the harbor floor serving as a letoff for ships that are too deep to enter any waterways. (usually a smaller boat is tied to the pilon)
But chances are that you are correct. This is also an old one (just like this puzzle: An electric train is traveling north at 200kph and there is a headwind of 160kph with southerly winds at 15kph, at what speed is the smoke traveling once it leaves the locomotive? )

Monica is correct.
Hehe...an electric train? So no smoke at all unless the brakes are burning .
Robert  guess what? I just got the family over the river. Yippee! I wasn't really trying this time and it happened in about 30 seconds. I'm kind of astonished. (and no, I did not cheat.) The little dance they all do at the end is a little weird, isn't it?
