Communicating underwater is challenging. Light and odors don’t travel well, but sound moves about four times faster in water than in air — which means marine mammals often use sounds to communicate. The most famous of these underwater vocalizations is undoubtedly the whale song. Stephanie Sardelis decodes the evocative melodies composed by the world’s largest mammals.

Philippe Beck. Poetry, between Hegel and Schiller. 2016

Philippe Beck is a contemporary French poet, writer, and philosopher. He is Professor of Poetry at The European Graduate School / EGS and Senior Lecturer of Philosophy at l’Université de Nantes. Interested in the nature of the poetic experience, for Beck, the poetic today lies not only between scientific experience and common sense experience but allows for their communicability. His work traverses poetry, poétologie, prose, and philosophy, as evidenced in his intellectual biography Beck l’impersonage, from 2006, and his latest work, Contre un Boileau, un art poétique, published this year. He has published sixteen books of poetry and was awarded the Grand Prix de Poésie (Grand Poetry Prize) from the French Academy in 2015 in recognition of his poetic oeuvre.

Beck began his advanced studies in literature and philosophy at L’École normale supérieure de Saint-Cloud in 1985. He went on to complete his doctoral studies at L’École des hautes études en sciences sociales under the supervision of Jacques Derrida, receiving his doctorate degree with honors in 1994 with his dissertation entitled Histoire et imagination (History and Imagination).
Beck’s poetry is highly influenced by his philosophical education. Following Derrida’s particular way of writing, many of Beck’s poetic works are conceived as comments on other texts. Often “metatextual” and “intertextual,” Beck’s poetry functions as a kind of palimpsest. They are, as well, often self-reflexive, as in the case of Garde-manche hypocrite (Hypocritical Oversleeve), his first book of poetry published in 1996, and Garde-manche deux (Oversleeve Two), a revised version of the former published in 2003. In Chants populaires (Folk Songs), from 2007, Beck reinvents seventy-two fairytales originally written by the Brothers Grimm. However, he does not simply paraphrase or retell these stories, but rather, in poetic form, offers interpretations and commentaries with the aid of psychoanalysis, sociology, and philosophy.

The Wolfgang Pauli Lectures 2016 are dedicated to Biology. In this lecture Prof. James E. Rothman, Yale University, New Haven, USA (2013 Nobel Prize in Physiology or Medicine) traces the lines of basic discoveries over the past century that resulted in vast improvements in public health in our time.

Pauli Lectures 2016: On the Sorting of Proteins to Compartmentalize the Cell

The Wolfgang Pauli Lectures 2016 are dedicated to Biology. Prof. James E. Rothman, Yale University, New Haven, USA (2013 Nobel Prize in Physiology or Medicine) is renowned for discovering the molecular machinery responsible for transfer of materials among compartments within cells. In so doing, Rothman provided a unified conceptual framework for understanding such diverse and important processes as the release of insulin into the blood, communication between nerve cells in the brain, and the entry of viruses to infect cells.
