Review of book by Carlo Rovelli
Clear and convincing description and explanation of quantum theory.
“The discovery of quantum theory … is the discovery that all the properties (variables) of all objects are relational, just as in the case of speed. Physical variables do not describe things: they describe the way in which things manifest themselves to each other.” p. 83
“… the relationship between two objects is not something contained in one or the other of them: it is something more besides. This interconnection between all the components of the universe is disconcerting.” p. 93
“… no universal set of facts exists.”
“… the relativity of reality.” p. 96
“… the world is not continuous but granular. There is no infinite in going toward hte small: things cannot get infinitely smaller. It tells us that the future is not determined by the present.” p. 108
