Quantum mechanics is constructed not as a description of properties of things but as a description of how things affect us when we interact with them, focusing on measurement outcomes rather than pre-existing intrinsic properties.

Rovelli's learning process showed that despite mastering quantum mechanics' formal apparatus as a student in the 1970s, he was not genuinely understanding it; years of reflection revealed the need for fundamental reconceptualization leading to his relational interpretation.

Quantum mechanics describes what happens at measurement interactions but says nothing about what happens between measurements; attempts to describe the in-between reality force us into problematic stories like Heisenberg's view that nothing exists between measurements, or wave-function descriptions where particles spread across space.

In relational quantum mechanics, the observer is also a quantum system, so an object manifests properties only relative to a specific observer, not absolutely; what you observe about me is different from what I observe about myself because we are in different relational positions.

Nagarjuna's philosophy, specifically its relational and anti-essentialist stance, has liberated Rovelli from metaphysical prejudices about independent reality that were blocking genuine understanding of quantum mechanics.

Systems have no properties by themselves, only properties relative to other systems; when a system manifests itself to an observer, that manifestation exists only as an interaction between the two, not as an intrinsic state.

If a system has no properties except those manifested in interactions, then there is nothing to describe about it between interactions—the system is, in a sense, nothing in itself, only the interactions matter.

Nagarjuna's philosophy teaches that entities in relation do not have independent reality by themselves; to talk meaningfully about relations, the relata themselves cannot have independent intrinsic being—this is the conceptual core needed to think coherently about quantum mechanics.

Nagarjuna's fundamental radicality lies in questioning any attempt to find a fixed, solid ground or starting point upon which to build understanding of reality; his negation is not about denying the conventional world but about rejecting the search for ultimate, independent reality.

Nagarjuna rejects the notion that mind is ultimate reality, and instead dissolves the conventional/ultimate reality distinction by refusing to ask what ultimate reality 'is'—opening an ontological space where conventional phenomena remain meaningful without needing metaphysical grounding.

Classical mechanics allows us to decompose the world into discrete systems with intrinsic properties; quantum mechanics, by contrast, blocks this approach by being constructed as a theory of measurement outcomes rather than intrinsic properties.

Particle-wave duality arises because we cannot consistently describe an electron as having a definite position between measurements; between manifestations as a particle, the electron must be described as a wave spreading through space, manifesting all positions simultaneously.

Rovelli was initially skeptical of connecting Indian or Chinese philosophy with modern science based on earlier unsuccessful attempts, but was persuaded by repeated suggestions from colleagues to engage with Nagarjuna.

The relational interpretation of quantum mechanics solves the interpretive crisis by showing that properties manifest relative to specific observers, making the measurement problem coherent: there is no gap between measurements because there is no 'state' independent of interaction.

Nagarjuna's approach is radically deflationary about metaphysics: it does not affirm alternative positive claims about reality but systematically negates all attempts to establish a fixed ground or ultimate foundation.

Time Is the Counting of Processes

Time is not something processes happen within; rather, time is the name we give to a set of processes that are next to one another — processes are fundamental and time is their counting, so reality at bottom consists of processes affecting other processes, with an object being merely a monotonous process that repeats itself.

Past/Future Asymmetry Is Thermodynamic Not Fundamental

The reason we treat the past as fixed and the future as open is that the present contains many traces of past events and few of future events — a contingent thermodynamic fact arising from the entropy gradient — not a fundamental feature of nature; microscopically, the past and future are exactly symmetric.

Properties Are How Things Affect Other Things

Quantum mechanics ultimately tells us we cannot break the world into objects with intrinsic properties; what the properties of a thing are is the way in which it affects other things, so there are no things by themselves — the world is a reciprocal reflection of partial internal perspectives with no external observer-independent point of view.

Rovelli Argues the Flow of Time Is Illusory

Carlo Rovelli works in a theory of quantum gravity with no time variable and argues that the experienced flow of time is illusory; time is just the counting of processes, and the apparent fixedness of the past versus openness of the future is not metaphysical but a thermodynamic fact — we have abundant traces of the past because we live in an entropy gradient.

Spacetime and gravitational field are identical

Einstein's stroke of genius in general relativity was realizing that Newtonian spacetime and the gravitational field are the same thing; gravity is not a thing that lives in spacetime but a manifestation of the nature of spacetime itself, which can therefore stretch, bend, and move.
