Source of Information

The insight of Bennett on Maxwell’s daemon shows that the information can not be easily erased. By the time symmetry of physical laws, the information can not be easily created, either.
There is this ad hoc observer in quantum mechanics that can collapse the state of a system and create information. And there is also this black hole of Hawking that seems to erase information. How are they connected?

Equivalent Trade

It’s more importance to recognize equivalence in things around us than to focus on favoritism. First of all, this helps us find different solutions to one given problem thus increase the chance of resolution. Secondly, this helps us choose quickly when the scale is tilted. Besides, we don’t need to invent/learn new tricks when the old ones will do.

Intended Prediction

It’s amazing to see people not being aware of how they are treating others. Is this generally true for all things they are interacting with? Or, is it a special thing for their interaction with other people? From the assumption of this article, the ability to predict the intention of others should be something natural. However, people don’t always use this ability when they are interacting with others.
