fd9 Posted June 6, 2005 Share Posted June 6, 2005 If anyone could help me decode the following cryptogram, I would be very thankful. abcdefeghijghkcmncopkqarsedieghkhtfjohfhrdircoathsfeghieifhhtkcmncopkqarshkankfnafhfqhicrkhciaffrfkfectphfuhhtfqho By the way, there's no spaces (I don't know why it put one in there).

calbiterol Posted June 7, 2005 Share Posted June 7, 2005 Is it encoded English? And does it have a context? Link to comment Share on other sites More sharing options...
fd9 Posted June 7, 2005 Author Share Posted June 7, 2005 yes it's in english, supposed to be a physics question. Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 say what? what's the question, like the entire thing? Link to comment Share on other sites More sharing options...
Phi for All Posted June 7, 2005 Share Posted June 7, 2005 If it's a substitution cipher, h is a good candidate for the letter e. 18 instances and two parings. Tough with no word spaces. There are actually 2 spaces in the text. You said you don't know why "it" put them there? Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 I'm assuming he means the thread starter. If you look at the beginning part, it goes like this: abcdefeghijghkcmncopkqars This immediately caught my eye. The underlined part is the english alphabet, in the correct order, with the exception of the letter L. How much of a coincidence could it be that it starts with a,b,c,d,e,f,...,g,h,i,j,...,k,C,m,n,...,o,p,...,q,...,r,s... That's about where it stops, but just the progression of letters caught my eye. That would make me think C is L. Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 Note also that there are no L's in the entire thing. Link to comment Share on other sites More sharing options...

Phi for All Posted June 7, 2005 Share Posted June 7, 2005 How much of a coincidence could it be that it starts with a,b,c,d,e,f,...,g,h,i,j,...,k,C[/b'],m,n,...,o,p,...,q,...,r,s.... In a substitution, he could have written out his question, then started assigning letters beginning with a, b, c, and so forth. Note also that there are no L's in the entire thing. Simply a low-instance letter like x or z. Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 I'm not sure I quite know what you mean... Link to comment Share on other sites More sharing options...
Phi for All Posted June 7, 2005 Share Posted June 7, 2005 I'm not sure I quite[/b'] know what you mean... a'b cde fghi a jgaei... = I'm not sure I quite... See the same pattern? You start the substitution at the beginning of the alphabet and apply it to the first words in the sentence. I think I have the last two words, which will help me get the rest.

calbiterol Posted June 7, 2005 Share Posted June 7, 2005 so as soon as you get to a repeat letter, it screws up the progression, right? I think i know what you mean now, I know what substitution is, but I'm a bit of a visual learner, or a do-it-myself-but-can't-explain-to-others kinda person, so I just didn't... see.

calbiterol Posted June 7, 2005 Share Posted June 7, 2005 Maybe one of the characters is a space. Link to comment Share on other sites More sharing options...
Phi for All Posted June 7, 2005 Share Posted June 7, 2005 No, they're all jammed together. If they used a letter as a space, you'd be missing a letter of the alphabet Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 No, I mean perhaps one of the letters they used stands for a space. As in, every Z means a space, just like every A could be a Z. Every g is immediately followed by an h. q and u, perhaps? Link to comment Share on other sites More sharing options...

calbiterol Posted June 7, 2005 Share Posted June 7, 2005 Nevermind, I think we're both misunderstanding each other, and it's a moot point, because it works without that entire idea. Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 Wouldn't happen to have any other letters? I think "fifteen" is in there. If you replace letters so that you get between them at the end, then you are left with a spot with "teen" (translated/transposed) and "iei" unchanged. That would mean i=f and e=i, but that seems to screw up other things. Also, it might be inbetween them. Link to comment Share on other sites More sharing options...
Phi for All Posted June 7, 2005 Share Posted June 7, 2005 A POSITIVE FIVE COULOMB CHARGE IS FIVE CENTIMETERS FROM A NEGATIVE FIFTEEN COULOMB CHARGE. CALCULATE THE FORCE OF ATTRACTION BETWEEN THEM. Negative, attraction, charge were all mispelled. Twenty lashes for the teacher. Or whoever copied it down wrong. Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 I noticed that too, and calculate was misspelled as well. It was driving me nuts. I got it to "A b o s i t i g e f i g e c o m n o m b c h a r s i s f i g e centimeters from a n e s t i g e fifteen c o m n o m b c h a r s e c a n c t n a t e t h e force of a t t r t ction between them" and was starting to go nuts with the "a t t r t ction " thing. Perhaps those spaces really were supposed to be there? There were at least 2, and I thought I might have counted 3. Just a thought. Good job, Phi!

fd9 Posted June 7, 2005 Author Share Posted June 7, 2005 Wow. Just, wow. That was amazing, how did you guys do that? I think I might have to do one more so can someone explain how you came up with that? What decoder did you use? By the way, thanks alot. Link to comment Share on other sites More sharing options...
calbiterol Posted June 7, 2005 Share Posted June 7, 2005 Minds work pretty well . If you have flash and want to try some true cryptograms (I spose it helps to know the definition of one, you should figure it out quick just looking at the puzzles) go to http://teppo.tv/cryptogram/ . The only difference is they use numbers instead of letters. Link to comment Share on other sites More sharing options...
Phi for All Posted June 7, 2005 Share Posted June 7, 2005 I think I might have to do one more so can someone explain how you came up with that? What decoder did you use?Decoder? How would a decoder work when there are no spaces to delimit words? I counted the letter instances and determined that h was a good possibility for the letter e. From there I just substituted randomly until the word "between" suggested itself. That gave me t and n, which both had high occurences and led me to the rest. It helped that I got "teen" and you told us it was a physics question, so I guessed it was probably a number in the teens. "Fifteen" worked and gave me another vowel. I want to know why there were so many misspellings. Did a physics teacher give you this puzzle? Was it not hard enough without them? Does he want students to turn his car over in the parking lot? Is he bigger than me? By the way, thanks alot.You are welcome alot. Your gratitude makes it worth staying up so late. Link to comment Share on other sites More sharing options...

[/quote'] Actually he told us there were misspellings, plus the enocded message were all random symbols before, so I had to transfer them to letters so I could easily use it on the computer. I might of screwed up somewhere. From the sound of it, it just seems to me like you guesstimated the whole thing. I still don't understand how you did it though. How do you "substitute randomly"? How did the word between suddenly "suggest itself" like magic? How long did it take you? Either you're an abnormally good guesser, or there's something I'm completly missing. Did you use a decoder at all? Link to comment Share on other sites More sharing options...
calbiterol Posted June 8, 2005 Share Posted June 8, 2005 FD9, check out the link I gave you. Try a few. It gives you word spaces, but the basic concept is the same - if you have no idea whatsoever, look at how often words come up and try letters.
