    Prehistory of Transit Searches

    Full text link
    Nowadays the more powerful method to detect extrasolar planets is the transit method. We review the planet transits which were anticipated, searched, and the first ones which were observed all through history. Indeed transits of planets in front of their star were first investigated and studied in the solar system. The first observations of sunspots were sometimes mistaken for transits of unknown planets. The first scientific observation and study of a transit in the solar system was the observation of Mercury transit by Pierre Gassendi in 1631. Because observations of Venus transits could give a way to determine the distance Sun-Earth, transits of Venus were overwhelmingly observed. Some objects which actually do not exist were searched by their hypothetical transits on the Sun, as some examples a Venus satellite and an infra-mercurial planet. We evoke the possibly first use of the hypothesis of an exoplanet transit to explain some periodic variations of the luminosity of a star, namely the star Algol, during the eighteen century. Then we review the predictions of detection of exoplanets by their transits, those predictions being sometimes ancient, and made by astronomers as well as popular science writers. However, these very interesting predictions were never published in peer-reviewed journals specialized in astronomical discoveries and results. A possible transit of the planet beta Pic b was observed in 1981. Shall we see another transit expected for the same planet during 2018? Today, some studies of transits which are connected to hypothetical extraterrestrial civilisations are published in astronomical refereed journals. Some studies which would be classified not long ago as science fiction are now considered as scientific ones.Comment: Submiited to Handbook of Exoplanets (Springer

    Revisiting the Early Modern Philosophical Canon

    Get PDF
    I reflect critically on the early modern philosophical canon in light of the entrenchment and homogeneity of the line up of seven core figures: Descartes, Spinoza, Leibniz, Locke, Berkeley, Hume, Kant. After distinguishing three elements of a philosophical canon -- a causal story, a set of core philosophical questions and a set of distinctively philosophical works -- I argue that recent efforts contextualizing the history of philosophy within the history of science subtly shift the central philosophical questions and allow for a greater range of figures to be philosophically central. However, the history of science is but one context in which to situate philosophical works. Looking at the historical context of 17th century philosophy of mind, one that weaves together questions of consciousness, rationality, and education, does more than shift the central questions -- it brings new ones to light. It also shows that a range of genres can to be properly philosophical, and seamlessly diversifies the central philosophers of the period

    Gardens of happiness: Sir William Temple, temperance and China

    This is the author accepted manuscript. The final version is available from Taylor & Francis via the DOI in this recordSir William Temple, an English statesman and humanist, wrote ā€œUpon the Gardens of Epicurusā€ in 1685, taking a neo-epicurean approach to happiness and temperance. In accord with Pierre Gassendiā€™s epicureanism, ā€œhappinessā€ is characterised as freedom from disturbance and pain in mind and body, whereas ā€œtemperanceā€ means following nature (Providence and oneā€™s physiopsychological constitution). For Temple, cultivating fruit trees in his garden was analogous to the threefold cultivation of temperance as a virtue in the humoral body (as food), the mind (as freedom from the passions), and the bodyeconomic (as circulating goods) in order to attain happiness. A regimen that was supposed to cure the malaise of Restoration amidst a crisis of unbridled passions, this threefold cultivation of temperance underlines Templeā€™s reception of China and Confucianism wherein happiness and temperance are highlighted. Thus Templeā€™s ā€œgardens of happinessā€ represent not only a reinterpretation of classical ideas, but also his dialogue with China.European CommissionLeverhulme Trus

    How Galileo dropped the ball and Fermat picked it up

    Get PDF
    This paper introduces a little-known episode in the history of physics, in which a mathematical proof by Pierre Fermat vindicated Galileo's characterization of freefall. The first part of the paper reviews the historical context leading up to Fermat's proof. The second part illustrates how a physical and a mathematical insight enabled Fermat's result, and that a simple modification would satisfy any of Fermat's critics. The result is an illustration of how a purely theoretical argument can settle an apparently empirical debate
