Abstract
What is information? What is its relation to Reality? I think we can ask these questions in another order: what is reality? isn't reality just all the information we could get from it? According to Niels Bohr, "There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature." So physics is all about "information", it's all about what we can say given some amount information (but never full amount information of reality). The philosophy is like duck test: If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck. So duck is from all those information.
