Abstract

Depuis quand et comment sait-on que la Terre n'est pas plate ? Comment fait le Soleil pour briller aussi fort et depuis si longtemps ? Nous savons tous beaucoup de choses : par exemple que la Terre est ronde et tourne autour du Soleil ; qui lui-même tourne autour du centre de la galaxie et qu'il brille depuis des milliars d'années... Mais saurions-nous raconter quand, comment et par qui ces connaissances ont été établies ? « Si on veut donner le goût des sciences, il faut d'abord leur donner du goût. » rappelle Étienne Klein. C'est la tâche relevée avec brio par Alain Riazuelo et Roland Lehoucq. Il fallait tout le talent de l'astrophysicien Roland Lehoucq pour mettre en scène cette épopée de la connaissance qui commence au VIe  siècle avant notre ère avec les Grecs Anciens, et s'achève aux dernières années du XXe siècle. Un texte qui illustre la puissance de l'intellect humain, excité par un beau problème. Éclairant à tout point de vue !

Abstract

"Monsignor Francesco Bianchini was the culture tsar of Rome under his friend Pope Clement XI, who reigned from 1700 to 1721. Famous as an astronomer, historian, and archaeologist, Bianchini also dabbled in high-stakes diplomacy and low-level espionage. Monsignor's scientific expertise ranged from observational astronomy to the imaginative reconstruction of ancient monuments. He discovered several comets; designed and built a glorious solar observatory in a Roman basilica; discovered and interpreted ancient inscriptions; and wrote an account of the first 32 centuries of human history, from the Creation to the fall of Assyria. During the first part of Clement's 20-year reign, which was dominated by the War of the Spanish Succession, Bianchini visited England while on a diplomatic mission to France. In London he met Newton, who esteemed him as one of the world's very few "candid seekers of truth," and in Paris he met James Stuart, the claimant to the thrones of Britain. When James set up his court-in-exile in Italy, his good friend Bianchini became one of the courtiers. Heilbron presents Bianchini as an exemplar of the churchman-diplomat-scholar of the time, deeply learned yet caught up in worldly affairs. Heilbron's account roves with ease, verve, and wit between erudition and antiquities, astronomy and history, and international and papal politics whose high point was the daring rescue of an imprisoned princess"--
