Flawed
I thought I had discovered something. I got jazzed about Rheticus and how he worked. I imagined his ultimate obscurity to be a glitch in history. I.e., great ideas are often attributed to the promoter rather than the creator. Yep, that's a romantic sentiment fueled by literature & movies. I got interested in the obelisk, which Rheticus lauded as 'The Key'. I was all set to try to emulate his techniques and sing praises to its great contributions as a scientific instrument. I picked up on Danielson's slant and enthusiasm, romanitic and sensational. This is where the book goes wrong. What is needed is a book that focusses on where Rheticus went wrong and why he is obscure, neglected, even scorned.

I started to research the obelisk as a scientific instrument, and came up empty-handed. Then I got a copy of "Obelisk: a History" (Curran, et al., 2009, The Burndy Library, Cambridge MA). This book points out that the secret of the obelisk is that it serves all purposes to all people. This book attributes two paragraphs to Rheticus, one sentence of which lauds him for publication of Copernicus' "Narratio primo". Following such a profound coup, perhaps it went to his head, Rheticus followed a path of "speculative natural science and alchemy". He was absorbed in mysticism & astrology. Scientifically, he regressed rather than progressed. These things were being left behind in science. Yet, Rheticus had such a damning influence that Kepler, in 1627, felt compelled to publicly address & refute Rheticus' theories. The obelisk, as an astronomical instrument, may have been used by Copernicus, but Copernicus' discovery was not new & better measurement. It was interpretation of known data. Rheticus felt Byzantine methodology, the way of the ancients, was the secret. I can imagine he felt they had discovered lost Truth, and what he had to do was replicate their accomplishment.

I suspect Rheticus, too, was romantic and sensational. It was his mission to redirect (misdirect, as it turns out) scientific effort. Rheticus' personal life was disreputable. Perhaps his professional motivations were self-serving and direputable. Rheticus, rightfully, gets credit for getting Copernicus published. Beyond that, he was a disreputable thorn to Enlightenment. To achieve scientific progress required that he be disreputed and disavowed. He earned obscurity, and that idea could make a great book. Danielson's interpretation is skewed. Because I fell into it also, I can understand the seductiveness of Rheticus, and Kepler's frustration with him.

Danielson's book seems well-researched and is worth reading for its thorough exposure of Rheticus. It is not an easy read. Yet, as is evident in this review, I have gotten a lot from having read it.

A rewarding read
Rheticus's indispensible role in helping Nicolaus Copernicus get his great book finished and published at the end of his life is well known in the history of science."No Rheticus, No Copernicus."Building on German sources and scholarship, what author Dennis Danielson provides here is the fuller story of the young German mathematician's career and legacy to the Copernican Revolution.He illuminates Rheticus's contributions both before and after the publication of Copernicus's seminal book.

Prof. Danielson explains for the first time what spurred Rheticus to do what he did and what became of him after his teacher died with Rheticus not yet thirty, and to some extent even how "his subsequent trigonometric research connected with his heroic mission as the first Copernican."One of the interesting suggestions in the book for me was that Rheticus's geometrical emphasis toward astronomy was the substantive connection between Copernicus and Kepler, that it ignited the development of the celestial mechanics to which Kepler devoted his life.Rheticus's posthumously published trig tables were extensive and accurate enough to be used for astronomical computation into the early twentieth century."Rheticus thus played a critical role not only in launching but also in extending the Scientific Revolution."

This book is not a fast read, but it's a rewarding read.I found myself underlining and reflecting a lot.Its 264 pages includes interesting appendices, endnotes, and index.A nice contribution to the history of the Scientific Revolution.

Along with Thomas Kuhn's masterful The Copernican Revolution: Planetary Astronomy in the Development of Western Thought and Owen Gingerich's facetiously titled The Book Nobody Read: Chasing the Revolutions of Nicolaus Copernicus, anyone seriously interested in the context surrounding how Copernicus launched modern astronomy would do well to have this book by Danielson in their library.

The unfinished book
This book was too boring to finish. It bogs you down in information without being an interesting story.

I enjoy astronomy books and astronomy history. One of my favorite books was "Tycho and Kepler: The Unlikely Partnership That Forever Changed Our Understanding of the Heavens". I got this book soon after reading that and thought it would grab me the same way. All it did was make my eyes heavy.

Some day I might pick it up and finish it, but as for now, I'm off reading better choices.

A good read
This book is delightful and fun to read and anyone interested in the history of scientific discovery will enjoy it.Danielson manages to bring to vivid life the story of Copernicus's great insight, how it survived the political, religious, and academic obstacles of its time to reach the hands of other scholars, and how the Copernicus manuscript might never have come down to us at all but for Rheticus, who himself was the founder of modern trigonometry.

While this is a very well-researched and scholarly book, I liked how Danielson brings the story alive, complete with the intrigue of the university politics and the national politics of the day.The author places you in the time.You feel the influence of Luther and Erasmus, patrons of the sciences, clerics of different stripes, dukes and mayors, and large scientific figures.And, for me what was interesting, the role of various competing academic institutions in the emerging nation-states of the Renaissance.That, and the story of all the tenuous links that must be secured before a great scientific idea comes to be accepted.

Danielson makes the personalities real: their intellectual struggles, what drives them, and their foibles.In particular, I found myself outraged at the academic treachery of Osiander, who sullied the first publication of the Copernican manuscript.And readers will find a soap opera element in the charges faced by Rheticus for allegedly molesting a male student.

Overall, I would recommend this book to anyone who would like to know the story of how the Copernican revolution began. ... Read more

Born in Hohenems, Klien started his motorsport career in his early teens. He raced in karting championships in both Austria and Switzerland, before moving to Formula BMW. After winning several titles in lower Formulas, Klien moved into Formula One, driving for the Jaguar Racing team, alongside Mark Webber. At the end of 2004, however, Jaguar sold its Formula One team to Red Bull, which renamed it Red Bull Racing. In an unusual arrangement, Klien shared a race seat with Italian Vitantonio Liuzzi. He stayed at Red Bull for 2006, whilst Liuzzi moved to the Red Bull junior team, Scuderia Toro Rosso. After an unsuccessful 2006, Klien's old teammate Mark Webber replaced him for the 2007 season. Klien was offered alternatives to Formula One for 2007, including driving in the ChampCar series, but he refused and aimed for a seat in Formula One. He secured the test driver's seat at Honda, despite competition from other drivers, including Gary Paffett.

Excerpt: Georg Joachim von Lauchen, also known as Rheticus (16 February 1514 4 December 1574), was a mathematician, cartographer, navigational-instrument maker, medical practitioner, and teacher. He is perhaps best known for his trigonometric tables and for being Nicolaus Copernicus' sole pupil, who facilitated the publication of Copernicus' De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres). Rheticus was born at Feldkirch, Austria. Both his parents possessed considerable wealth, and the father, Georg Iserin, was the town physician. However, he abused the trust of many of his patients, stealing belongings and money from their homes. In 1528 he was convicted and executed for his crimes, and as a result his family was stripped of their surname. The son took as his last name a form of the Latin name for his home region, Rhaetia, a Roman province that had included parts of Austria, Switzerland and Germany; he would be called Rheticus. The crater Rhaeticus is named for him. After Iserin's death, Achilles Gasser took over his medical practice. Gasser helped Rheticus continue his studies and was a strong support to him. Rheticus studied at Feldkirch, Zürich and the University of Wittenberg, where he received his M.A. in 1536. Philipp Melanchthon, the theologian and educator, greatly assisted Rheticus in obtaining appointments at several universities.

Gold was one of three young Cambridge scientists who in the 1950s proposed the now mostly abandoned 'steady state' hypothesis of the universe. Gold's work crossed academic and scientific boundaries, into biophysics, astronomy, aerospace engineering, and geophysics. Gold was born on May 22, 1920 in Vienna, Austria to Max Gold, a wealthy Jewish industrialist who ran one of Austria's largest mining and metal fabrication company, and former actress Josefine Martin. Following the economic downfall of the European mining industry in the late 1920s, Max Gold moved his family to Berlin, where he had taken a job as director of a metal trading company. Following the start of Nazi leader Adolf Hitler's anti-Jewish campaigns in 1933, Gold and his family left Germany and traveled through Europe for the next few years.

Mises à jour gratuites en ligne. Extrait : Georg Joachim von Lauchen, surnommé Rheticus ("originaire de Rhétie", la Rhétie romaine correspondant à peu près à l'actuel Tyrol) est un astronome et mathématicien autrichien, né à Feldkirch (Vorarlberg) le 15 février 1514, mort à Kassa (Hongrie) le 4 décembre 1574. Il est passé à la postérité comme celui qui décida Copernic à publier sa théorie héliocentrique (1541-1543). Né d'une famille aisée du Tyrol autrichien, Rheticus voyagea enfant en Italie. Puis il étudia dans les universités de Zurich, de Wittenberg (où il devint le protégé de Melanchthon), Nuremberg et Göttingen. À 22 ans, Melanchthon lui confia les chaires de Mathématiques et d'Astronomie de la toute jeune université luthérienne de Wittenberg. Informé des idées de Copernic sur l'héliocentrisme, il obtint l'autorisation de son université de se rendre à Frauenburg pour rencontrer Copernic, malgré la désapprobation de Luther, et malgré les persécutions que l'évêque de Varmie, Dantiscus, exerçait contre les Luthériens. Rheticus expliqua plus tard (1543) qu'il avait souhaité rencontrer Copernic parce qu'il venait d'être nommé professeur d'astronomie à l'université de Nuremberg et qu'il se sentait par trop ignorant de cette discipline. Arrivé à Frauenburg à l'été 1539, Rheticus y passa deux années au côté de l'astronome, cartographe et mathématicien Johann Schöner. Copernic n'avait alors écrit qu'un Commentariolus (entre 1510 et 1514, selon Koyré) sur ses hypothèses cosmologiques, fascicule qui n'avait circulé qu'en un très petit nombre d'exemplaires.

Non illustré. Mises à jour gratuites en ligne. Extrait : Kurt Gödel (28 avril 1906 - 14 janvier 1978) est un mathématicien et logicien austro-américain. Son résultat le plus connu, le théorème d'incomplétude de Gödel, affirme que n'importe quel système logique suffisamment puissant pour décrire l'arithmétique des entiers admet des propositions sur les nombres entiers ne pouvant être ni infirmées ni confirmées à partir des axiomes de la théorie. Gödel a également démontré la complétude du calcul des prédicats du premier ordre. Il a aussi démontré la cohérence relative de l'hypothèse du continu, montrant qu'elle ne peut pas être réfutée à partir des axiomes admis de la théorie des ensembles, en admettant que ces axiomes soient cohérents. Il est aussi à l'origine de la théorie des fonctions récursives. Le plus souvent considéré comme Autrichien, il est né à Brno en Autriche-Hongrie, naturalisé Tchécoslovaque à 12 ans, puis Autrichien à 23 ans. Lorsque Hitler ordonne l'annexion de l'Autriche, Gödel devient Allemand (il a alors 32 ans). Il part aux États-Unis pendant la Seconde Guerre mondiale, et il obtient la double nationalité austro-américaine à 42 ans. Il a publié ses résultats les plus importants en 1931 à l'âge de 25 ans, alors qu'il travaillait encore pour l'Université de Vienne (Autriche).

Extrait : Johann Palisa (né à Troppau, Autriche (maintenant en République tchèque) le 6 décembre 1848, et mort le 2 mai 1925 à Vienne) est un astronome autrichien. Il est le découvreur autrichien d'astéroïdes le plus prolifique. Il est également l'auteur de deux catalogues qui mentionnent la position de près de 4,700 étoiles. Johann Palisa a découvert 122 astéroïdes, de l'astéroïde (136) Austria découvert en 1874 à (1073) Gellivara en 1923. De 1866 à 1870 Johann Palisa étudie les mathématiques et l'astronomie à l'Université de Vienne. Il est brièvement astronome assistant aux observatoires de Vienne et de Genève. En 1871, il est nommé directeur de l'Observatoire Naval austro-hongrois situé à Pula (aujourd'hui en Croatie). Il consacre ses premières observations aux planètes mineures. Le télescope a seulement un diamètre de 6 pouces et les conditions d'observations sont meilleures qu'à Vienne. En 1874, il trouve son premier objet et le nomme en honneur de l'Empire, (136) Austria. Il découvrit par la suite 27 autres objets à Pula. De 1880 à 1919, il est membre de l'équipe d'astronome à l'Observatoire de Vienne. Palisa découvrit à cet endroit 94 autres objets, tous par des observations visuelles. L'un des astéroïdes découvert par Palisa en 1911, 719 Albert a été perdu suite à sa première observation à cause d'inexactitudes sur son orbite.

Excerpt: Emil Artin (March 3, 1898, in Vienna December 20, 1962, in Hamburg) was an Austrian-Armenian mathematician. The mathematician Emil Artin was born on March 3, 1898 in Vienna to parents Emma Maria, née Laura (stage name Clarus), a soubrette on the operetta stages of Austria and Germany, and Emil Hadochadus Maria Artin, Austrian-born of Armenian descent. Several documents, including Emils birth certificate, list the fathers occupation as opera singer though others list it as art dealer. It seems at least plausible that he and Emma had met as colleagues in the theater. They had been married in St. Stephen's Parish on July 24, 1895. Emil entered school in September 1904, presumably in Vienna.

Extrait : Michel de Nostredame, dit Nostradamus, né le 14 décembre 1503 à Saint-Rémy-de-Provence, et mort le 2 juillet 1566, est un apothicaire français (on dirait en français moderne : pharmacien). Selon bien des sources, il aurait également été médecin, bien que son expulsion de la faculté de médecine de Montpellier témoigne qu'il n'ait pas été possible d'être les deux à la fois.
