Received: Published: August 18, 2021; August 31, 2021 Abstract The history of epilepsy is intermingled with the history of human existence dating back to antiquity. Hippocrates, the founder of scientific medicine, was the first to de-mystify the condition of epilepsy by providing a more scientific approach to it. Since then, many centuries have passed until the recording of electrical waves was applied. First in experimental animals and close to the hu- th century, William Gilbert Galileo and Thomas Willis man brain. The birth of epileptology was characterized by the advent of electroencephalography and the delineation of underlying Cybulski and Jelens- pathophysiological mechanisms. Starting in the 16-17 investigated electricity of ka-Macieszyna various substances, and Otto von Guericke developed the first electrostatic apparatus. About two centuries later , published photographs of EEG, and some years later Hans Berger published its results. From then on, the progress to electroencephalography was rapid in all areas.

  • Ampere, the Etherians, and the Oersted Connexion
    AMPERE, THE ETHERIANS, AND THE OERSTED CONNEXION KENNETH L. CANEVA* IN 1826 Andre-Marie Ampere published the 'Mathematical theory of electrodynamic phenomena, uniquely derived from experiment', in which he showed how the mathematical law for the force between current elements could be derived from four ingenious equilibrium experi- ments.1 He made a great show of following a Newtonian inductivist methodology, and his law, like Newton's for gravitation, was presented as a purely descriptive mathematical expression for a certain class of pheno- mena, one for which its author did not provide any causal or ontological justification. Ampere's electrodynamics would accordingly seem to have been a solid contribution to the Laplacian-Newtonian approach to physics so actively pursued in France during the first quarter of the nine- teenth century.2 It does not surprise us to read that his electrodynamic force law and his molecular-currents theory of magnetism were immedi- ately and widely accepted by his French contemporaries.3Ampere was, in this view, just another of the many great French mathematical physicists of the period. There are, however, serious problems with this picture. For one, Ampere's work was not warmly received by his contemporaries.4 In fact, those who were the coldest were among those who should have been the warmest if the acceptability of a theory was simply a function of its mathematical-descriptive success. The three most prominent representa- tives of the style of physics which had been dominant in France during the first two decades of the nineteenth century, Laplace, Biot, and Poisson, were either hostile or silent.

    Isaac Newton’s sinister heraldry Alejandro Jenkins∗ Escuela de F´ısica, Universidad de Costa Rica, 11501-2060 San Jos´e, Costa Rica (Dated: Oct. 2013, last revised Jul. 2014) After Isaac Newton was knighted by Queen Anne in 1705 he adopted an unusual coat of arms: a pair of human tibiæ crossed on a black background, like a pirate flag without the skull. After some general reflections on Newton’s monumental scientific achievements and on his enigmatic life, we investigate the story of his coat of arms. We also discuss how its simple design illustrates the concept of chirality, which would later play an important role in the philosophical arguments about Newton’s conception of space, as well as in the development of modern chemistry and particle physics.
