Crypto challenge

Postby theme » Sat Nov 02, 2013 5:26 pm UTC

I'm giving an encrypted text as a string of seemingly random digits. Can anyone decrypt it?
73519-825359-98423-7862147 82-974631 7982-714693-9746413 71254-9746413-974631-7982 7158539-9746413-71254-98423-4862-1752593-82-98423
If nobody solves it I will post some hints :D

EDIT: corrected mistake by deleting an extra word at the end of the code, so it should be a proper sentence

Spoiler:
XKCD is the best webcomic of

(∫|p|2)(∫|q|2) ≥ (∫|pq|)2
Thanks, skeptical scientist, for knowing symbols and giving them to me.

Cauchy, your answer is right! Congrats! I didn't expect it to be solved this quick!
I somehow got an extra word in the end of the code, making the answer an incomplete sentence. I'm deleting the extra word.
BTW you are supposed to put the answer in a spoiler tag

I know this topic is ancient, but can someone point me to how this was solved. Thanks!

If you have a full-size computer keyboard with numeric pad, look at the positions of the number 1-9 keys there as a grid. Within each string of numbers in the code, imagine drawing lines between the corresponding points in the grid, and the shapes you'll be drawing are just (a low-resolution attempt at) letters.

Thank you, curiosityspoon!
