There is no doubt that scientific information must be transmitted between scientists through texts reviewed by peers and published in academic journals (if they are in the Q1 range, better than better) so that the whole process transmits confidence, reliability and accuracy.
But how to make some of these conclusions reached in a paper reach the general public? Regardless of the nuance that we introduce in the answer to this question (and that has to do with our meaning of "popularization" and "vulgarization"), the truth is that 400 years ago the first scientists were born who already wanted to make knowledge accessible people (even if it was using some rhetorical and persuasive techniques).
One of the first great popularizers and scientists in history was the German astronomer Johannes Kepler (1571-1630), a key figure in the scientific revolution, and known mainly for his laws on the movement of the planets in their orbit around the Sun.
Kepler decided to put on the cover of his book Stella nova (New Star, 1606) the image of a hen pecking the ground of a farm , with the motto ("looking in manure, finds a grain"), as he was engaged in the work of looking for objective facts, but also in the work of transmitting them: for this reason, he adopted many of the rhetorical techniques that are currently used in the most popular dissemination:
- An apparently prolix story in irrelevant details but that contextualize and bring the reader closer to the narrated event (the burning coal with which he read his instruments on the night of February 19). This device is what Roland Barthes called "the reality effect."
- The determination to report failures as well as successes as a way to show the process of trial and error, the epic background of reaching a peak.
- The insistence on involving the reader as if he were really present (here he even introduces us to his wife, as if we were visiting his house, and that she replies on some occasion or other, as we can read in the following fragment, about the fact that the universe could be the result of chance):
Yesterday, when I was tired of writing and my mind was full of specks of dust from thinking about atoms, he called me to dinner and served me a salad. Whereupon I said, "If we threw the pewter plates, the lettuce leaves, the grains of salt, the drops of oil, vinegar and water, and the glorious eggs into the air, and all these things would remain there for all eternity, So would this salad fall all together by chance? My beauty replied: "But not in this presentation, not in this order).
In the 19th century, this type of narrative became the ideal of the historian, but in the 17th century it was not the historian, but the scientist , who aspired to this kind of realism and proximity, with Kepler at the head. Kepler was interested in relating this story in order to convince his readers that his measurements were accurate, rather than simply using mathematics or scientific evidence. He was also trying to make the aridity of the data more digestible.
Still , Kepler still did not use humor , laughter (although his wife’s comment did exude a certain irony) in order to prevent rigor from turning into rigor mortis. Something that other great popularizers would later rule out, and even groups of comedians like Monty Python (and countless other people connected in one way or another with their members, as you can see in the following video):
Thus it no longer seems so singular that Somnium sive Astronomia lunaris Joannis Kepleri (The Dream or Astronomy of the Moon by Johannes Kepler) was a fictional novel written in Kepler Latin in 1608, considered by many to be the first science fiction work of the world. history , although both its title and elements of its plot coincide with those of a 1532 work by the Spanish humanist Juan Maldonado.
