Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious... As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness.

«Ci sono frontiere, dove stiamo imparando, e brucia il nostro desiderio di sapere. Sono nelle profondità più minute del tessuto dello spazio, nelle origini del cosmo, nella natura del tempo, nel fato dei buchi neri, e nel funzionamento del nostro stesso pensiero. Qui, sul bordo di quello che sappiamo, a contatto con l'oceano di quanto non sappiamo, brillano il mistero del mondo, la bellezza del mondo, e ci lasciano senza fiato». Tale è il presupposto di queste «brevi lezioni», che ci guidano, con ammirevole trasparenza, attraverso alcune tappe inevitabili della rivoluzione che ha scosso la fisica nel secolo XX e la scuote tuttora: a partire dalla teoria della relatività generale di Einstein e della meccanica quantistica fino alle questioni aperte sulla architettura del cosmo, sulle particelle elementari, sulla gravità quantistica, sulla natura del tempo e della mente.

Focusing on the visual aspects of national identity in post-Independence Mexico, the book explores the often-overlooked role of visual culture beyond renowned muralists. It spans from the early nineteenth century to modern times, analyzing how illustrated periodicals, literature, and the works of graphic artists, filmmakers, and photographers reflect and reshape discourses on ethnicity and cultural hybridity. The study highlights the eclectic and self-reflexive nature of Mexican visual discourse, revealing its complexity and significance in shaping national identity.

The official centenary commemorating the Mexican Revolution of 1910 provided scholars with an opportunity to consider memorialization and its legacies and ‘afterimages’ in the twentieth century through to the present time. This collection of new essays, commissioned from experts based in Mexico, Europe and the United States, plays on the interrelated notions of ‘revisitation’, haunting, residual traces and valediction to interrogate the Revolution’s multiple appearances, reckonings and reconfigurations in art, photography, film, narrative fiction, periodicals, travel-testimonies and poetry, examining key constituencies of creative media in Mexico that have been involved in historicizing, contesting or evading the mixed legacies of the Revolution. The interplay of themes, practices and contexts across the chapters (ranging from the 1920s through to the present day) draws on interdisciplinary thinking as well as new findings, framing the volume’s discourse with a deliberately multi-dimensional approach to an often homogenized topic. The contributors’ scholarly referencing of artists, novelists, poets, photographers, foreign correspondents, critics, filmmakers and curators is detailed and wide-ranging, creating new juxtapositions that include some rarely studied material.
