The way it works is a letter stands for another letter. For example: AXYDLBAAXR is LONGFELLOW (does not apply to today's cryptogram).
Beware, the game is very addictive. If this is your first time, don't be intimidated, you’ll be solving them all within a few days. If you’re stumped, take a break and return to it.
PLEASE DO NOT post the answer in general comments, but DO post your time and how you made out.
You can certainly send your solution to my private reply, or if you need a hint for today’s Cryptogram ASK THE GROUP FOR HELP!
I suggest printing these out and work them on paper. If you need a little help you can copy and paste it to Hal’s Helper below.
You can then work on the puzzle without using pen and paper, but I recommend that you do NOT look at the letter counter.

One last request. Feel free to post a fun or clever clue, the more tangential to the quotation the better, but please don’t put the actual words of the quote in the clue.## ping list message
If you need a clue ask the group to send you a letter to your private reply.

Long ones are easy!
They are. It’s easier to find patterns of letters for common words or common letter combinations.
Good one today, although I was actually primed to look for today’s subject.
I was going for an interesting topic more than a difficult puzzle. Your observation is, of course, correct:
https://en.wikipedia.org/wiki/Unicity_distance
In cryptography, unicity distance is the length of an original ciphertext needed to break the cipher by reducing the number of possible spurious keys to zero in a brute force attack. That is, after trying every possible key, there should be just one decipherment that makes sense, i.e. expected amount of ciphertext needed to determine the key completely, assuming the underlying message has redundancy.
Claude Shannon defined the unicity distance in his 1949 paper "Communication Theory of Secrecy Systems".
Thanks.

No one would have believed, in the last days of the 19th Century, that human affairs were being watched from the timeless worlds of space.
No one could have dreamed that we were being scrutinized, as someone with a microscope studies creatures that swarm and multiply in a drop of water.
Few men even considered the possibility of life on other planets.
And yet, across the gulf of space, minds immeasurably superior to ours regarded this earth with envious eyes, and, slowly and surely, they drew their plans against us ...

What's up, Doc?
Deja vu all over again.
