1. What is the total quantity of information entropy in the universe? 2. Instead the appropriate quantity to maximise is the " relative information entropy ," 3. Indeed, information entropy can be used as an index of qualitative variation. 4. The question of the link between information entropy and thermodynamic entropy is a debated topic. 5. According to this principle, the distribution with maximal information entropy is the proper one. 6. Shannon's information entropy is a much more general concept than statistical thermodynamic entropy. 7. Entropy, if considered as information ( see information entropy ), is measured in bits. 8. At an everyday practical level the links between information entropy and thermodynamic entropy are not evident. 9. The logarithm can also be taken to the natural base in the case of information entropy . 10. This is the case of the unbiased bit, the most common unit of information entropy .
