Descartes' Circle Theorem, Princess Elizabeth, and Spinors
Daniel Parrochia
In this article, on Descartes' famous "circle theorem," we first attempt to explain how the philosopher could have arrived at the equation that he presents without demonstration in…
From Schwartz Space to Structural Aging (Towards a small history of Old Age mathematics)
Daniel Parrochia
Starting with some historical considerations, we examine the various attempts to model old age that fall within the realm of mathematical physics. For example, we study the mathema…
On complemented, uniquely complemented and uniquely complemented nondistributive lattices (a historical and epistemological note about a mathematical mystery)
Daniel Parrochia
Complemented lattices and uniquely complemented lattices are very important, not only in mathematics, but also in physics, biology, and even in social sciences. They have been inve…
Global warming in figures and the question of its treatment: some historical and epistemological views
Daniel Parrochia
We first recall fundamentals of elementary climate physics: solar constant, radiative balance, greenhouse effect, astronomical parameters of the climate (theory of Milankovitch). W…
A "network of networks" (from history to algebra)
Daniel Parrochia
Recall first the algebraic treatment of flows or tensions in a transportation network , i.e. a connected antisymmetric 1-graph . Assume that, unusually, we take the val…
On von Weizsäcker's philosophy of Quantum Mechanics
Daniel Parrochia
We are interested here in the program of reconstruction of quantum mechanics of the German physicist and philosopher Carl Friedrich von Weizsäcker, which still has some supporters…
Pacotte tree networks, graph theory and projective geometry
Daniel Parrochia
The notion of tree network has sparked renewed interest in recent years, particularly in computer science and biology (neural network). However, this notion is usually interpreted…
Are there really many worlds in the "Many-worlds interpretation" of Quantum Mechanics?
Daniel Parrochia
Since the 1970s, the Everett-Wheeler many-worlds interpretation (MWI) of Quantum Mechanics (1955) has been much in the news. One wonders about the worlds in question, their branche…
Majorana equation and its consequences in physics and philosophy
Daniel Parrochia
We focus here on the work of the italian physicist Ettore Majorana, and more particularly on his 1937 article on the symmetrical theory of the electron and the positron, probably o…
Some remarks on history and pre-history of Feynman path integral
Daniel Parrochia
One usually refers the concept of Feynman path integral to the work of Norbert Wiener on Brownian motion in the early 1920s. This view is not false and we show in this article that…
on some (so-called) paradoxes of quantum physics
Daniel Parrochia
This article is devoted to the study of which appears as the most famous paradoxes of quantum theory (Schrodinger cat, EPR argument and Aspect experiments, delayed choice experimen…
