Henri Poincaré, The logic of infinity: The cardinal number
| |

We must not forget the preceding considerations when defining the cardinal number. If we consider two collections, we may seek to establish a law of correspondence between the objects of these two collections, so that any object of the first … Read More

Henri Poincaré, Why space with three dimensions – Analysis Situs (Topology)
| |

Geometers usually distinguish two kinds of geometries, which they call the first of metric and the second of projective; metric geometry is based on the notion of distance; two figures are regarded as equivalent when they are “equal” in the … Read More

(The wave-particle duality, in which we can see how the same phenomenon can be perceived in two different ways, was one of the philosophical problems posed by quantum mechanics.) The philosophy of physics refers to the set of philosophical reflections … Read More

Ontology of Gravitational Singularities
| |

Peter Bokulich and Erik Curiel (Curiel and Bokulich 2018) assert that general relativity (GR) allows singularities, and that we need to understand the ontology of singularities if we want to understand the nature of space and time in the present … Read More

Gravitational Singularities
| |

Within the classical theory of Newton’s gravity there is the fundamental possibility of singularity. No signal can propagate from within a singularity, but its gravitational influence is permanently present externally and depends only on the total mass, the angular momentum, … Read More

But obviously, after the publication of Principia in 1687, … Read More

The Ontology of General Relativity
| |

In classical vision, space and time are containers; matter is the content. The distinctive property of matter is that it carries energy and impulse, preserved over time, resulting in energy and impulse being fundamental ontologically. (Norton 2012) General Relativity (GR) … Read More
