This is the subject of my teachings, and I go on to describe
all the possible causes of the stars’ movement across the Universe.
Of these hypotheses, only one must be the correct explanation,
but what animates the bodies in the sky is still beyond the grasp
of those who move at an honest pace through the path to Truth.

As for the quote from the poem On the Nature of Things by Lucretius, an early example of scientific divulgation, 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” (R) that seems to follow the footprints of these few lines from the fifth book of De Rerum Natura. Verses 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.

Spot Finder, a regression analysis

Abstract My ME/CFS regularly improves during the summer. In a previous study, I found that the improvement correlates with air temperature but not with other environmental parameters. In a simulation of summerish conditions performed in a room, during cold months, by artificially increasing air temperature, infrared radiation, and air humidity, the correlation between my symptoms…

La maledizione di Didone

Aeneis, Liber IV, v 607-621 Sole, tu che illumini i giorni umani, Giunone, che sai del mio dolore, Ecate, che tormenti i sonni urbani. E voi Dire e dèi d’Elissa che muore, se sventura benevolenza vale, ascoltatemi. Poiché l’impostore le ancore getterà al litorale e questo Giove comanda che accada, almeno che un nemico eccezionale…

La cognizione del dolore

1. Una resurrezione Cosa pensò Michelangelo, in quel giorno di gennaio del 1506, davanti al gruppo del Laocoonte, appena dissotterrato da un campo, sul Colle Oppio? Michelangelo aveva quasi 31 anni: siamo dopo il Bacco, la Pietà e il David; prima della Cappella Sistina, e delle statue originariamente intese per la tomba di Giulio Secondo,…
