Was geht mich die Physik an?: Physikalisch denken in Gesellschaft, Politik und Management.

by Reiner Kree

Politische Themen mit wissenschaftlichem Bezug werden medial immer präsenter. In Talkshows, Zeitungen und politischen Beratungsgremien finden oft Expertinnen und Experten mit Physikausbildung Gehör. Egal, ob es um Klimawandel, Finanzmarktcrashs, Pandemiepolitik oder erneuerbare Energien geht: wir müssen den Aussagen dieser Expertinnen und Experten blind vertrauen, wenn wir selbst kein Fachwissen besitzen. In diesem Buch werden physikalische Grundlagen hinter gesellschaftlich relevanten Themen auf eine allgemeinverständliche Weise erklärt. Dabei geht es vor allem darum, die für die Physik typischen Denkweisen klar zu machen. Auf welchen Grundlagen (Mechanik, Elektrodynamik, Quantentheorie, Feldtheorien, Relativitätstheorien, Statistische Physik) beruhen eigentlich physikalische Aussagen? Wie sind diese Grundlagen entstanden? Wie erstellt man in der Physik Modelle zur Beschreibung komplexer Themen? Was ist „Wahrheit" in Wissenschaften? Wie ist das Verhältnis von Modellen zur Wirklichkeit? Beim Beantworten dieser und vieler weiterer Fragen hat der Autor darauf geachtet, nur Mathematik vorauszusetzen, die das Niveau der Mittelstufe nicht überschreitet. Der vorliegende Band richtet sich an alle, die für Entscheidungen und Urteile ein einfaches aber solides Verständnis des physikalischen Denkens suchen: sei es im Alltag, in Unternehmen oder in der Politik.

The Water Engine: Editorial Alvi Books

by Ares Van Jaag

The "water engine" is an invention unfortunately invented many times. Hydrogen from water is very abundant, renewable and can be used in both energy poor and rich countries. Crude oil and natural gas are limited energy resources. But there are many people who think that certain promising technologies have been suppressed by various political or economic powers, usually with the purpose of protecting their investments and interests and, at the already more absurd extremes of the conspiracy illogical, for sinister motivations of much greater scope. In this new work, the versatile composer and writer Van Jaag, accompanies us on an exciting journey through the history of this unknown invention and its invented inventors.

Water in Biomechanical and Related Systems (Biologically-Inspired Systems #17)

by Adam Gadomski

The contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance.Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants’ roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply.The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system’s properties, mostly those of mechanical nature. The presented work’s chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters’ contents underscore the bioinspiration as the key landmark of the proposed monograph.

Water Resources Management and Sustainability (Advances in Geographical and Environmental Sciences)

by Pankaj Kumar Anju Singh Gaurav Kant Nigam Manish Kumar Sinha

Water is the elixir of life and is crucial for sustainable development. Earlier, it was considered to be a limitless or at least a fully renewable natural resource. During the past 20 years, however, there has been tremendous pressure on this precious natural resource mainly due to rapid urbanization, industrialization and the increase in the human population. Together, these have resulted in increasing demand for irrigation, industrial, and household purposes to meet supply-chain requirements. Keeping in mind the scarcity of available water resources in the near future and its impending threats, it has become imperative on the part of scientists in hydrology and allied disciplines such as geography, landscape planning, sustainability science etc. Regional planners and supply chain management experts also must be involved in studying the spatial and temporal nature of the growing demand for water and the future availability for its judicial use and sustainable management. A primary intent of the book is to provide comprehensive scientific knowledge base on water resource management and sustainability. It covers geo-engineering and scientific problems, case studies, and sustainable solutions in the water resources management domain. Additionally and of equal importance, the chapters of the book provide in-depth coverage on water resource vulnerability, water quality, wastewater treatment, application of remote sensing and geographical information systems hydrological modeling and harvesting, climate variability and runoff, sediment discharge and irrigation planning, community participation in water governance, internet of things and machine learning applications for sustainable water resources management. This practical, state-of-the-art reference book is a valuable resource for students, researchers, scientists, policymakers, spatio-temporal designers of water resource systems, various stake holders interested in hydro-climatology and sustainable water resources management.

It goes viral. Suddenly, Elijah and Kristen are in a new spotlight as the online backlash spins out of control. And the consequences are bigger than they both could have ever imagined because these threats don't stay online...they follow them into real life.

The Way of the Intellectual Dark Web: What Joe Rogan and His Associates Can Teach Us about Political Dialogue

by Jamie Q Roberts

Roberts presents a rigorous and accessible assessment of the Intellectual Dark Web’s origins, shared philosophy, cultural importance, and limitations. Since the mid-2010s, the Intellectual Dark Web (IDW) has been an unprecedented cultural and intellectual phenomenon. Using primarily podcasts and YouTube videos, a new generation of public intellectuals has appeared, loosely coalesced, and gained a vast global audience. This movement has encompassed a range of individuals, notably Joe Rogan, Jordan Peterson, Eric and Bret Weinstein, Ben Shapiro, Heather Heying, and Sam Harris. Other names more broadly associated with the grouping have included Steven Pinker, Jonathan Haidt, Elon Musk, Niall Ferguson, and Stephen Fry. There is a sprawling and ever-growing list of those who have appeared on IDW podcasts and videos, started their own podcasts along similar lines, and share a general ethos. It is a dispersed movement, but a significant one, given the reach of these various online outlets is in the millions globally. Roberts draws together and synthesises the core ideas espoused by the members of this movement and critically assesses its origins, coherence, and the impact it has had on politics and public discourse. He asks – to what extent has the IDW lived up to its professed goal of moving beyond polarisation and radicalisation? An insightful read both for followers of the IDW looking for a coherent and critical overview and for students of popular culture looking to understand this massive but decentralised popular intellectual movement.
