Understanding Quantum Mechanics in terms of relations and mutual information Relational Quantum Mechanics is a way of thinking about quantum phenomena that avoids hidden variables, many worlds, or excessive subjectivism. It is based on the idea of treating quantum systems and observers on the same footing, and on the idea that physical properties are not intrinsic: they describe how systems affect one another. I describe how this way of thinking about quantum phenomena improvesupon the conventional Copenhagen interpretation, and how it leads to a natural formulation of quantum theory in information theoretical terms. Time permitting, I also briefly describe why this way of viewing quantum mechanics can be suitable for quantum gravity, where the quantum behavior of spacetime itself is not neglected.
