"[2] As he told The Chronicle of Higher Education, Sternheimer did not consider himself an expert in all the topics Grichka Bogdanov included in his thesis, but judged that those portions within his specialty were PhD-quality work. [71], Igor and Grichka Bogdanov have and had vigorously insisted upon the validity of their work, while in contrast, Sokal was an outsider to the field in which he was publishinga physicist, publishing in a humanities journaland promptly issued a statement himself that his paper was a deliberate hoax. Genealogisches Handbuch des Adels, Frstliche Huser XIX. Since 1991, they signed their books as "Bogdanov", preferring "v" to "ff". [58][59] Mia Jovanovi, the rector and owner of Megatrend University, wrote a preface for the Serbian edition of Avant le Big Bang. As per the French newspaper Le Monde, Grichka died in Paris from COVID . The BBC said the un Majid also described more than ten other modifications of meaning, each one biased towards "surestimation outrancire""outrageous over-estimation". The death of Igor Bogdanoff, 72, was confirmed on Monday evening by his lawyer Edouard de Lamaze, as well as his agent. Though they have a strange aura and physical appearance that gets them a lot of media attention, they are intellectuals with doctorate degrees in science. [11], In 2001 and 2002, the brothers published five papers (including "Topological field theory of the initial singularity of spacetime") in peer-reviewed physics journals. [13] Sociologist of science Harry Collins noted that all of the early reports of the incident made reference to the Sokal affair, and he speculated that without Sokal's precedent bringing the idea of hoax publications to mind, the Bogdanov papers would have sunk into the general obscurity of non-influential scientific writing. Igor and Grichka Bogdanoff starred in '80s French sci-fi shows. Schreiber concluded, Just to make sure: I do not think that any of the above is valid reasoning. News of Bogdanoff's death comes just days after his twin brother, Grichka, passed away. "[40] This was not confirmed officially by HKU and no Prof. Yang existed on the roster of the HKU physics department; nor did the university have an "International Institute of Mathematical Physics". The twin celebrities and scientists first rose to fame as co-hosts of the television show 'Temps X', which blended science and science . . Presenter Grichka Bogdanoff has died at the age of 72. Paris Controversial French TV stars and famous twins Igor and Grichka Bogdanoff were inseparable in life, and in death.They had refused to be vaccinated against the coronavirus, believing . The French mainstream media, in both the press and on the Internet, covered the renewed controversy to some extent; media outlets that reported upon it include Acrimed[15] and Ciel et Espace. When your name is used without your consent, it's a violation. "[20][21], Copies of the email reached American mathematical physicist John C. Baez, and on 23 October he created a discussion thread about the Bogdanoffs' work on the Usenet newsgroup sci.physics.research, titled "Physics bitten by reverse Alan Sokal hoax? [10] The story spread in public media, prompting Niedermaier to offer an apology to the Bogdanovs, admitting that he had not read the papers firsthand. The Bogdanov affair was an academic dispute regarding the legitimacy of a series of theoretical physics papers written by French twins Igor and Grichka Bogdanov (alternatively spelled Bogdanoff). [4]) Baez, who made a comparison between the two affairs, later retracted, saying that the brothers "have lost too much face for [withdrawing the work as a hoax] to be a plausible course of action". Igor was born 40 minutes before Grichka. The Bogdanovs quickly became a popular discussion topic, with most respondents agreeing that the papers were flawed. In 1999, Grichka Bogdanoff earned a mathematics Ph.D. from the University of Burgundy (Dijon). Guillaumin noted that "the twins totally deny this sad odyssey. [70] The physicist John Baez compared the two events in his October 2002 post to the sci.physics.research newsgroup. [9] That journal ceased publication in 2005. "[26], Not all review evaluations were positive. In April 2012, a group of 170 scientists published an open letter titled L'affaire Bogdanoff: Libert, Science et Justice, Des scientifiques revendiquent leur droit au blme (The Bogdanoff Affair: Liberty, Science and Justice, scientists claim their right of critique). There is no logic or cohesion in what they write. The two have been involved in a number of controversies, most notably the Bogdanov affair, however, their personalities, family origins, and physical appearances are often more than enough fodder for Internet forums.. Posted in . [29][30], Robert Oeckl's official MathSciNet review of "Topological field theory of the initial singularity of spacetime" states that the paper is "rife with nonsensical or meaningless statements and suffers from a serious lack of coherence", follows up with several examples to illustrate his point, and concludes that the paper "falls short of scientific standards and appears to have no meaningful content. D'origine russe, il tait n le 28 janvier 1928 Saint-Ptersbourg. Physics bitten by reverse Alan Sokal hoax? In Calaque's estimation, the results presented in the preprint did not have sufficient novelty and interest to merit an independent journal article, and moreover the principal theorem was, in its current formulation, false: Grichka Bogdanov's construction yields a bialgebra which is not necessarily a Hopf algebra,[31] the latter being a type of mathematical object which must satisfy additional conditions. After several rounds of plastic surgery and botox, the brothers ended up with a shocking appearance. However, as per the news, Grichka has passed away at the age of 72. This almost goes without saying; for a quantum system, the KMS condition is just the concrete definition of thermodynamic equilibrium. Les frres Bogdanoff ont quatre frres et surs plus jeunes: Franois, Laurence, Graldine et Vronique. The papers were published in reputable scientific journals, and were alleged by their authors to culminate in a theory for describing what occurred before and at the Big Bang. [12] Soon after, Freidel denied writing any such remarks, telling the press that he had forwarded a message containing that text to a friend.[12]. In May 2001, the journal Classical and Quantum Gravity (CQG) reviewed an article authored by Igor and Grichka Bogdanov, titled "Topological theory of the initial singularity of spacetime". Igor and Grichka Bogdanoff became famous in the 1980s after hosting sci-fi shows on French TV, and became well known for their dramatic plastic surgery in recent years, despite denying they had . Both were 72. The paper was discussed extensively at the annual Editorial Board meeting and there was general agreement that it should not have been published. "[19] The paper was accepted by the journal seven months later. But if one accepts that the papers about these difficult questions don't have to be just a well-defined science but maybe also a bit of inspiring art, the brothers have done a pretty good job, I think. Prior to the controversy, the reports on the Bogdanov theses and most of the journal referees' reports spoke favorably of their work, describing it as original and containing interesting ideas. [11] Nobel laureate Georges Charpak later stated on a French talk show that the Bogdanoffs' presence in the scientific community was "nonexistent". Igor Yourivitch Bogdanoff (French pronunciation:[i jui.evit bdanf]; 29 August 1949 3 January 2022) and Grgoire "Grichka" Yourivitch Bogdanoff (French:[ewa ika]; 29 August 1949 28 December 2021) were French twin television presenters,[1] producers, and essayists who, from the 1970s on, presented various subjects in science fiction, popular science, and cosmology. Rather than suing Riazuelo for defamation, Bogdanoff filed a criminal complaint of copyright (droit d'auteur) violation against him in May 2011. "[2], In 2001 and 2002 the brothers published five papers in peer-reviewed physics journals, including Annals of Physics and Classical and Quantum Gravity. The fifth and last "result", Schreiber notes, is an attempt to resolve this contradiction by "invok[ing] quantum mechanics". There is, after all, a long-standing meme that the twins are able to control the market. First the earth cooled. They were both (could still be, I dunno) TV presenters and producers, and scientific essayists. French news outlets have reported that Grichka, who was best known for his work alongside twin brother Igor . And Prince Charles started wearing all of Lady Di's clothes. [37], Alain Riazuelo, an astrophysicist at the Institut d'Astrophysique de Paris, participated in many of the online discussions of the Bogdanoffs' work. It is the Hong Kong University of Science and Technology which is located in Clear Water Bay, not Hong Kong University (HKU), whose main campus is located in the Mid-Levels of Hong Kong Island. Igor and Grichka Bogdanoff are fraternal twin brothers born to Yuri Mikhalovitch Osten-Sacken-Bogdanoff (1928-2012), a Russian painter of Tatar origin and descent from a line of Prince Bogdanoff, and to Maria Maya Dolores Franzyska Kolowrat-Krakowsk (1926-1982). 12729. They lived a similar life in everything. Igor was the first born and his brother Grichka was born 40 minutes later. Yikes.
