Monsoons: global energetics and local physics as drivers of past, present and future monsoons

Global constraints on momentum and energy govern the structure of the zonal mean tropical circulation and rainfall. The continental-scale monsoon systems are also facets of a momentum- and energy-constrained global circulation, but their modern and paleo variability deviates substantially from that of the longitudinal mean through mechanisms neither fully understood nor well simulated. A framework grounded in global constraints yet encompassing the complexities of monsoon dynamics is needed to identify the causes of mismatch between theory, models, and observations and, ultimately, improve regional climate projection. In a first step towards this goal, disparate regional processes must be distilled into gross measures of energy flow in and out of continents and from the surface to the tropopause, so that monsoon dynamics may be coherently diagnosed across modern and paleo observations and across idealized and comprehensive simulations. Accounting for zonal asymmetries in the circulation, land/ocean differences in surface fluxes, and the character of convective systems, such a monsoon framework would integrate our understanding at all relevant scales: from the fine details of how moisture and energy are lifted in the updrafts of thunderclouds, up to the global circulations

Vampires in the village Žrnovo on the island of Korčula: following an archival document from the 18th century

Središnja tema rada usmjerena je na raščlambu spisa pohranjenog u Državnom arhivu u Mlecima (fond: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) koji se odnosi na događaj iz 1748. godine u korčulanskom selu Žrnovo, kada su mještani – vjerujući da su se pojavili vampiri – oskvrnuli nekoliko mjesnih grobova. U radu se podrobno iznose osnovni podaci iz spisa te rečeni događaj analizira u širem društvenom kontekstu i prate se lokalna vjerovanja.The main interest of this essay is the analysis of the document from the State Archive in Venice (file: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) which is connected with the episode from 1748 when the inhabitants of the village Žrnove on the island of Korčula in Croatia opened tombs on the local cemetery in the fear of the vampires treating. This essay try to show some social circumstances connected with this event as well as a local vernacular tradition concerning superstitions

Liquid crystals: a roundtable

This Roundtable began life as a public event on the subject of liquid crystals in our visual, material, media, scientific and artistic cultures. The event’s premise was that liquid crystals are the ur-form that constitute and govern Modernity and its after-shocks. For sure this is because the dialectic of liquidity and crystallization, of flow and refraction, is key to the advent of screen-based media (LCD TVs, computers and mobile devices) and thus how we perceive, image and imagine the world. As such, liquid crystals as a ‘phase of matter’ are epochal. But more than this because, while the emergence of such a brave new world is manifestly contemporary and their ‘discovery’ is comparatively recent (1888), the very fact of liquid crystals goes back at least 4.5 billion years: water, for instance, is crystalline and thus our planet, our ecology and we ourselves are always already liquid crystal. Such a self-evident but underacknowledged fact, discerned and foregrounded superbly by Esther Leslie in her recent book Liquid Crystals: The Science and Art of a Fluid Form (2016), becomes an occasion to bring together historians, theorists and practitioners of the convergences of design-science, media-ecology, political-aesthetics, and graphic-technologies. Using Leslie’s book as a springboard, each of the five contributors, including Leslie herself, were invited to deliver a 10-minute presentation, an opening statement to set the scene, and raise fundamental questions to be considered further in the ensuing discussion. This structure is retained here, along with some of the informality that live conversation afford
