"Gilbert Romme et la communauté scientifique pétersbourgeoise (1779-1786)"

Lire la présentation de la correspondance de Gilbert Romme http://chec.univ-bpclermont.fr/article127.htmlChoisi comme gouverneur du jeune Pavel Stroganov, Gilbert Romme séjourne en Russie de la fin 1779 au printemps 1786. Le père de son élève l'introduit très vite auprès des membres de l'Académie des sciences de Saint-Pétersbourg et il se lie plus particulièrement avec Peter Simon Pallas. Pourtant sa correspondance avec ses compatriotes et amis riomois reste très discrète sur ses lectures et sur les activités intenses et variées qu'il mène dans la capitale russe. Les Notes scientifiques et anecdotes viennent combler cette lacune. Romme, en effet, est devenu une véritable plaque tournante entre les savants pétersbourgeois et parisiens. Lui-même voit sa curiosité naturelle et sa réflexion stimulées par ces contacts qui font naître chez ce mathématicien et physicien des intérêts nouveaux, d'ordre linguistique par exemple, en phase avec ceux de son époque

Optical Classification of Gamma-Ray Bursts in the Swift Era

We propose a new method for the classification of optically dark gamma-ray bursts (GRBs), based on the X-ray and optical-to-X-ray spectral indices of GRB afterglows, and utilizing the spectral capabilities of Swift. This method depends less on model assumptions than previous methods, and can be used as a quick diagnostic tool to identify optically sub-luminous bursts. With this method we can also find GRBs that are extremely bright at optical wavelengths. We show that the previously suggested correlation between the optical darkness and the X-ray/gamma-ray brightness is merely an observational selection effect.Comment: 6 pages, 3 figures; accepted for publication in Ap

A Most Fateful Encounter: How Scipio Africanus Defeated Hannibal Barca at the Battle of Zama

This thesis addresses the question of why Hannibal Barca suffered such a decisive defeat at the hands of Scipio Africanus in the Battle of Zama. I begin by conducting a thorough analysis of the two ancient sources that have provided us with the bulk of what is known about the battle and the events leading up to it. My analysis of them primarily concerns itself with determining how objective and trustworthy these accounts are, and as such how much faith can be placed in the details they provide. Using these sources, I then proceed to examine the events leading up to the Battle of Zama itself, specifically Scipio\u27s campaign in North Africa and how his strategic decisions and maneuvers ultimately forced Hannibal to return to North Africa and confront him. I then conduct an analysis of the battle itself and each general\u27s tactical performance. Before drawing my own conclusions as to why Hannibal lost, I review the texts of scholars who have also written on the subject to determine what they believe were the factors responsible for Hannibal\u27s defeat, categorizing them into two major schools of thought. Finally, I choose one side and then add my own contributions as to why Scipio Africanus triumphed in the end

Keeping Members United in Contentious Times

[Excerpt] In contentious times, members often don’t see eye to eye, generating division and rivalries that undermine solidarity. Increasing membership diversity can lead to misunderstandings, which can escalate to disrespect. As a steward, you play a critical rol

Industry clusters and SMEs

Studie naar de rol van clusters van bedrijven in de economie. Clusters van bedrijven krijgen een groeiende aandacht op alle bestuurlijke niveaus. De achterliggende gedachte is dat samenwerking tussen bedrijven op technologisch gebied leidt tot de creatie van extra toegevoegde waarde, niet alleen voor de samenwerkingspartners zelf, maar ook voor de lokale, regionale en nationale economie. In de studie wordt een clusterdefinitie gepresenteerd en een raamwerk dat als basis kan dienen voor nader onderzoek naar de rol en positie van het MKB in clusters.
