Ecrit exceptionnel de Charles Péguy, la note sur M. Descartes parle cependant de tout sauf de René Descartes. Le grand philosophe n'est en effet que le prétexte introductif à un voyage à travers les méandres clairs et sinueux si caractéristique de la pensée de Péguy, et notamment ses thèmes fétiches : la pensée de Bergson, grand penseur du temps ; le Juif et le Chrétien ; le catholicisme ; l'écriture et le durcissement de la pensée ; la Grâce et la Sainteté.Ces dernières sont au coeur de l'ouvrage : Péguy ne se lasse pas, dans des réflexions d'une force rigoureuse et d'un lyrisme tenu, d'analyser à travers elles de grandes figures comme le Polyeucte de Corneille, Saint-Louis et Jeanne d'Arc ; mais aussi de revenir en longueur sur la chevalerie française, la royauté, l'Histoire de France. A travers ces cheminements si pleins d'une nécessité qui lui est propre, Péguy revient ensuite longuement sur la sainteté de Jésus, sur l'avilissement du monde moderne, l'épargne, l'avarice et même les fonctionnaires et la retraite.Un livre d'un charme, d'une profondeur et d'une fascination infinies, dans lequel s'épanouit le meilleur de Péguy.

This book will help you quickly learn to program for microcontrollers and IoT devices without a lot of study and expense. MicroPython and controllers that support it eliminate the need for programming in a C-like language, making the creation of IoT applications and devices easier and more accessible than ever. MicroPython for the Internet of Things is ideal for readers new to electronics and the world of IoT. Specific examples are provided covering a range of supported devices, sensors, and MicroPython boards such as the Raspberry Pi Pico and the Arduino Nano Connect RP2040 board. Programming for microcontrollers has never been easier. The book takes a practical and hands-on approach without a lot of detours into the depths of theory. It'll show you a faster and easier way to program microcontrollers and IoT devices, teach you MicroPython, a variant of one of the most widely used scripting languages, and is written to be accessible to those new to electronics. After completing this book, and its fun example projects, you'll be ready to ready to use MicroPython to develop your own IoT applications. What You Will Learn Program in MicroPython Understand sensors and basic electronics Develop your own IoT projects Build applications for popular boards such as Raspberry Pi Pico and Arduino Nano Connect RP2040 Load MicroPython on compatible boards Interface with hardware breakout boards Connect hardware to software through MicroPython Explore connecting your microcontroller to the cloud Develop IoT projects for the cloud Who This Book Is For Anyone interested in building IoT solutions without the heavy burden of programming in C++ or C. The book also appeals to those wanting an easier way to work with hardware than is provided by platforms that require more complex programming environments.

Environment as a Weapon considers how the confluence of war and nature from the time of the Agricultural Revolution (10,000 BCE) to our present day has been represented in works of history, geography, and literature. In the Epic of Gilgamesh, the Torah and Greco-Roman myths, warfare is a trope commensurate with environmental disasters, extreme climate, and plague. In the medieval age myths the Táin, and Beowulf environments become allies and enemies. The equestrian steppeland as foundation of Genghis Khan’s and his heirs Pax Mongolica is chronicled in The Secret History of the Mongols and The Travels of Marco Polo. The West African Griot legend of Sundiata and the Little Ice Age wreck of the Spanish Armada in 1588 speak to oceanic and atmospheric dimensions of warfare. American Revolution political pamphlets, poetry, diaries and weather logs, reflect the severe weather and terrain deployed by George Washington’s early campaigns in the war of independence. Napoleon’s midwifing of Total War is captured in Mary Shelley’s Frankenstein, Leo Tolstoy’s War and Peace, and Charles Minard’s Carte figurative carto-graph of the disastrous 1812 French invasion of Russia. The U.S. Civil War and the organic-industrial assembles of its battles, arguably the first Anthropocene War, is parsed by the clarifying poetry of Emily Dickinson. Geopolitik and geo-hazards of flood and fire feature in the Global War works of Samuel Beckett, Kurt Vonnegut and James Dickey. The literature of Vietnamese and American war combat veterans reveals how North Vietnam’s Environmental Military Complex stalled the American Military Industrial Complex in the jungles, and R&R districts of southwestern Asia. Finally, he sci-fi of H.G. Wells’ World Set Free and David Mitchell’s Cloud-Atlas frame Oppenheimer’s sub-atomic deployments at Hiroshima and Nagasaki, James Lovelock’s ‘Gaia’ and U.S. military discourses situating global warming as a national security threat to America. Indeed, Environment and War ironically resonates with U.N. Secretary General António Guterres proclamation that “seventy-five years ago, the world emerged from a series of cataclysmic events: two successive world wars, genocide, a devastating influenza pandemic . . . Our founders gathered in San Francisco promising to save succeeding generations from the scourge of war.” Thus, a holistic approach to studying and mitigating the human and environmental impacts of warfare, must integrate methods from the arts, humanities and sciences. This involves understanding how the historical geographies of the Earth’s planetary systems have been perceived, deployed and emerged as agents of warfare, with the lithosphere, hydrosphere, cryosphere, biosphere and atmosphere transformed as arsenals against anthropogenic global warming. This book will be of interest to geographers, historians, and scholars in environmental studies, climate change, literature and military studies, as well as the broader environmental humanities.
