Yep, and that's why the whole concept of entropy and especially negentropy is superfluous, it's just lack of information ! http://www.av8n.com/physics/thermo/e

(However, it is perhaps useful to separate them into two concepts when teaching the 19th century thermodynamics, since it would be hard to avoid questions about the subjectivity of information ?)
- IIAOPSW 4y agoI agree profoundly with everything except "the concept is superfluous". Yes its just a lack of information, or as I say it "entropy is the name of the bits you don't have." That's a profoundly useful thing. You can talk about the password entropy (the bits in the search space for the password you don't have), the mutual entropy (how many bits does Alice have that Bob is missing) etc.
- BlueTemplar 4y agoYes, I was perhaps too radical here. But the usefulness is akin to "syntactic sugar", and in some cases not realizing that they are fundamentally the same concept can be harmful in itself...
