RE: From Entropy to Consciousness [Part 1]
As always a very interesting article.
That entropy is information you dont have, sounds very interesting but it is kind of hard to understand.
Is unknown information a kind of energy?
Looking forward to your next articles!
ok when this entropy is information you dont have, than cryptography is about maximising the entropy of a message like a string. Iformation stored needs energy (we could argue on this one) but besides this fact, this term refers only to information (there is of course a connection between all those "entropys"). But shannon-entropy is all about the bits a system holds. It is observer dependent. If you throw a coin (with maximum entropy of 1bit) and you look on the outcome, you reduce the entropy to 0bit. Getting information means reducing shannon-entropy. Now there is only 1bit of information. For me it can still be 1bit of entropy...untill you show me the result.
If the result is a password, than i can guess it easily with maximal two guesses. Its head or tail. If you use 30 coins/bits it would be still easy but when sequence(reihenfolge) matters, it gets a lot harder. And with a sha256 it takes multi-million of years for me to guess it. Because there is a lot information I dont have.
Ah great comment, i think i understand that part now:D
Really interesting topic
