This is the subject of my teachings, and I go on describing all the different causes the movement of the stars across the Universe might spring from. Among these hypotheses, only one must be the right explanation, but which one deserves the crown is still beyond the grasp of those who move at an honest pace through the path to knowledge.

As for the quote from the poem On the Nature of Things by Lucretius, an early example of scientific divulgation, I’ve crafted a translation that sacrifices adherence to the original hexameters and gives up on metric, in favor of the inner meaning that I think these verses bear. The original hexameters in Latin are the following ones:

… id doceo, plurisque sequor disponere causas,
motibus astrorum quae possint esse per omne;
e quibus una tamen sit et hic quoque causa necessest,
quae vegeat motum signis; sed quae sit earum
praecipere haudquaquam est pedetemptim progredientis.

Titus Lucretius Carus, De Rerum Natura, V 529-533

The reader may have recognized some similarities with ideas promoted by natural philosophers who were born after Galileo had started the scientific revolution, about sixteen centuries apart from the end of Lucretius’ life. Besides the obvious “Hypotheses non fingo” by which Newton admitted that even though his mathematical model described so well the movement of planets, he had no idea of the cause of gravity; besides that, we can also mention Chamberlin’s “Method of Multiple Working Hypotheses” that seems to follow the footprints of these few lines from the fifth book of De Rerum Natura. Lines in which almost a presage of the convergence of a Baconian series can perhaps be acknowledged; a prophecy that has traveled through twenty centuries to teach us what we have painfully learned again during this vertiginous hiatus and that we often forget about.

An estimation of the proportion of asymptomatic Omicron infection

Abstract In this document, I compare data from two COVID vaccine trials carried out in South Africa (the Ubuntu trial and the Sisonke sub-study). Both trials were conducted on unvaccinated subjects, asymptomatic at the time of enrollment. Among them, some were found positive to SARS-CoV-2, but while the variant was identified as Delta in the … Continue reading An estimation of the proportion of asymptomatic Omicron infection


A collection of some of my artworks, made during these last 20 years. I would like to write some notes on each one of them; I might do it in the future.

La búsqueda de Borges

“A las dificultades intrínsecas debemos que añadir que Averroes, ignorante del siríaco y del griego, trabajaba sobre la traducción de una traducción.” Jorge Louis Borges, La busca de Averroes Tengo insomnio en este periodo: la noche no puedo dormir, si no hasta que la noche misma no está lista para el sueño. Y no es … Continue reading La búsqueda de Borges
