BULGARIAN REVIVAL INTELLIGENTSIA Natural
BULGARIAN REVIVAL INTELLIGENTSIA Natural Philosophy System of Dr. Petar Beron Petar Beron was born at year 1800 in the town Kotel, “a miniature of Nuremberg”, in a rich family of handcrafts and merchants. In Kotel he received his primary education at the cell school of Stoiko Vladislavov and Raino Popovich. He went further to Bucharest where he entered the school of Greek educator Konstantin Vardalach. The latter, a famous for his time pedagogue and encyclopedist, had influenced a lot for the formation of Beron as scientist and philosopher. In 1824 Beron is compelled to leave Bucharest, because he participated in a “Greek plot”, and goes to Brashov, another Rumanian town, where he compiled “The Fish Primer”. This book was fundamental for the Reformation in Bulgaria and an achievement for the young scholar. In 1825 Beron enrolled as a student in Heidelberg University, Germany, where he proceeded philosophy until two years later when he transferred to Munich to study medicine. On the 9 July 1831, after successfully defending a doctoral dissertation, Beron was promoted Doctor in Medicine. Dissertation was in Latin and concerned an operation technique in Obstetrics and Gynecology. The young physician worked in Bucharest and Craiova, but after several years of general practice he quit his job and started merchandise. After fifteen years he made a fortune and went to Paris where he lived as a renter. Here he started a real scientific career. His scope was to entail all the human knowledge by that time and to make a natural philosophy evaluation by creating a new “Panepisteme”. His encyclopedic skills were remarkable. -

Writing the History of Dynamical Systems and Chaos
Historia Mathematica 29 (2002), 273–339 doi:10.1006/hmat.2002.2351 Writing the History of Dynamical Systems and Chaos: View metadata, citation and similar papersLongue at core.ac.uk Dur´ee and Revolution, Disciplines and Cultures1 brought to you by CORE provided by Elsevier - Publisher Connector David Aubin Max-Planck Institut fur¨ Wissenschaftsgeschichte, Berlin, Germany E-mail: [email protected] and Amy Dahan Dalmedico Centre national de la recherche scientifique and Centre Alexandre-Koyre,´ Paris, France E-mail: [email protected] Between the late 1960s and the beginning of the 1980s, the wide recognition that simple dynamical laws could give rise to complex behaviors was sometimes hailed as a true scientific revolution impacting several disciplines, for which a striking label was coined—“chaos.” Mathematicians quickly pointed out that the purported revolution was relying on the abstract theory of dynamical systems founded in the late 19th century by Henri Poincar´e who had already reached a similar conclusion. In this paper, we flesh out the historiographical tensions arising from these confrontations: longue-duree´ history and revolution; abstract mathematics and the use of mathematical techniques in various other domains. After reviewing the historiography of dynamical systems theory from Poincar´e to the 1960s, we highlight the pioneering work of a few individuals (Steve Smale, Edward Lorenz, David Ruelle). We then go on to discuss the nature of the chaos phenomenon, which, we argue, was a conceptual reconfiguration as -
Spiking Neurons and the First Passage Problem
LETTER Communicated by Daniel Tranchina Spiking Neurons and the First Passage Problem Lawrence Sirovich [email protected] Laboratory of Applied Mathematics, Mount Sinai School of Medicine, New York, NY 10029, U.S.A. Bruce Knight [email protected] Center for Studies in Physics and Biology, Rockefeller University, New York, NY 10065, U.S.A. We derive a model of a neuron’s interspike interval probability density through analysis of the first passage problem. The fit of our expression to retinal ganglion cell laboratory data extracts three physiologically rele- vant parameters, with which our model yields input-output features that conform to laboratory results. Preliminary analysis suggests that under common circumstances, local circuitry readjusts these parameters with changes in firing rate and so endeavors to faithfully replicate an input signal. Further results suggest that the so-called principle of sloppy work- manship also plays a role in evolution’s choice of these parameters. 1 Introduction The pattern of electrical discharge event times, recorded from a neuron by a microelectrode in a vertebrate’s central nevous system, largely depends on three macroscale parameters: local synaptic input current s, in response to signals from other neurons, the transmembrane ohmic rate constant γ , proportional to transmembrane conductance, and the intracellular level of stochastic voltage noise, which may be expressed as a diffusion coefficient. Here we develop an expression for a neuron’s interspike-interval proba- bility density distribution in terms of these three variables. Our procedure assigns to the recorded neuron a simplified dynamical model, whose input- output dynamics, in some studied cases, conforms well with laboratory results. -

Interview with Mathmedia
i “Taiwan-I-12-transcript2” — 2013/11/7 — 15:23 — page 1 — #1 i i i Interview with MathMedia Interviewee: Frans Oort Interviewer: Ching-Li Chai Venue: Institute of Mathematics Academia Sinica Date: December 3rd, 2012 Ching-Li Chai(CHAI): Good morning, Frans. Doing this interview is a pleasure. I didn’t expect this. Frans Oort (OORT): The pleasure is mine. It’s a surprise for both of us. CHAI: There is a ritual that we first invite people to talk about their formative years which is always interesting because people’s backgrounds are all different. Would you like to say something about your formative years or when you are younger and decided to go to mathematics? Some people believe that mathematicians are born. The beginning1 OORT: Let me first say something about life as a mathematician, and later I will tell some stories about my personal life. For me it is a surprise you can be together with other people, with different cultural backgrounds, in history, in bringing up, with parents on the one hand, while on the other hand you can be so close to other people. With other mathematicians all of a sudden you understand each other on a much higher level than you ever thought possible. This is one of the most exciting things I have seen in my life. Certainly this is true with my collaborator here; with Ching-Li I have so much in common, and we understand each other. I think mathematically we have a deep contact and I am very grateful for that.
