Tracing uraniums past, and how it intersects with our understanding of other radioactive elements, this book aims to disentangle our attitudes and to unpick the atomic mindset.Chain Reactions looks at the fascinating, often-forgotten, stories that can be found throughout the history of the element. Ranging from glassworks to penny stocks; medicines to weapons; something to be feared to a powerful source of energy, this global history not only explores the development of our scientific understanding of uranium, but also shines a light on its cultural and social impact.By understanding our nuclear past, we can move beyond the ideological opposition to atomic technology and encourage a more nuanced dialogue about whether it is feasible - and desirable - to have a genuinely nuclear-powered future.

Wir sind Pioniere und gehen voran. Wir machen aus Sonnenstrahlen Strom und anschlieend speisen wir den Strom ins eigene Hausnetz ein. So sparen wir nicht nur Strom, sondern auch CO2 ein. Wir retten die Welt, den es werden immer mehr, die sich uns anschlieen. Balkonkraftwerke sieht man bereits uberall und taglich werden es mehr. Lucas Wolf zeigt dir mit seinem Buch, wie es geht.

Aerospace engineering encompasses a broad range of disciplines, including aerodynamics, which studies how air flows around objects like aircraft wings; propulsion systems, which power vehicles through the atmosphere or space; materials science, which focuses on developing lightweight yet durable materials for aerospace applications; and avionics, which involves designing and implementing electronic systems for navigation, communication, and control.Additionally, aerospace engineers work on structural design to ensure that vehicles can withstand the stresses of flight and space travel, as well as thermal management to regulate temperatures in extreme environments. They also contribute to the development of guidance and control systems to maintain stability and control during flight.Moreover, aerospace engineering extends beyond Earths atmosphere, with space exploration being a significant area of focus. This includes designing spacecraft for missions to satellites, communication and observation, etc. Overall, aerospace engineering plays a crucial role in advancing our understanding of the universe and expanding our capabilities beyond the confines of our planet.

Augusto Righi (1850-1920) e stato uno dei massimi scienziati italiani e un pioniere della Fisica a livello mondiale.Tra i fondatori nel 1884 del Circolo Matematico di Palermo, membro dellAccademia dei Lincei e di numerose istituzioni scientifiche italiane e straniere, nel 1905 Righi venne nominato senatore del Regno dItalia per i suoi meriti scientifici.Le sue ricerche abbracciarono un campo vastissimo: studi sui condensatori, sullelettroforo di Volta, sui dielettrici e sulle scintille elettriche, sui fenomeni ottici e magneto-ottici, sullisteresi magnetica; fu il primo a dimostrare leffetto di isteresi nei materiali ferromagnetici e il suo contributo allo studio degli effetti di Hall e Kerr ne porto alla luce alcuni aspetti fondamentali, che sarebbero stati spiegati solo successivamente, ma la sua fama e soprattutto legata allo studio delle radiazioni elettromagnetiche.Le ricerche sulle onde elettromagnetiche pongono Righi, assieme a Heinrich Rudolf Hertz, Nikola Tesla, Oliver Joseph Lodge, Alexander Stepanovitch Popov, fra i precursori di Guglielmo Marconi.Il saggio di Augusto Righi Lintima struttura della materia, che oggi riproponiamo allattenzione dei nostri lettori, tratto da un suo discorso pronunciato a Parma nel 1907 in occasione del Congresso della Societa Italiana per il Progresso delle Scienze, costituisce uno dei classici della letteratura scientifica italiana.

Jag har i denna bok valt att skriva om familjen Viperidae, huggormarna. For mig borjade mitt intresse med den huggorm som finns i svensk natur, numera har jag ett antal huggormsarter i terrarium hemma i kallaren. Boken beskriver familjen huggormar och tar sedan upp sex olika arter i varsitt kapitel (urvalet ar helt baserat p vad jag har for arter i hemmet). Utover detta s tar boken upp en hel del begrepp inom herpetologin och zoologin som kan vara bra att kunna, vad man ska gora om man blir biten och vad man bor fundera p innan man tar steget att skaffa ormar som kan vara farliga for ens halsa.

Die faszinierende Welt der Zeit und des Zufalls verstandlich und spannend erklart.Warum wiederholen sich manche Vorgange scheinbar zeitlos, wie die Bewegung der Erde um die Sonne? Sonne und Erde ein System, das nicht zu altern scheint. Was unterscheidet dieses System von anderen, die eine klare Zeitrichtung haben? Wenn wir morgens in den Spiegel schauen, merken wir sofort: Alternde Systeme sind real!Noch nie hat jemand beobachtet, wie sich eine goldbraune Flussigkeit plotzlich entmischt und Milch und Kaffee fein sauberlich getrennt nebeneinander zur Ruhe kommen. Ist bei Systemen mit erkennbarer Zeitrichtung die unerwartete Verwandtschaft von Zeit und Zufall die entscheidende Zutat?Was ist Zufall? Ist es der Mangel an Kenntnis oder die grundsatzliche Abwesenheit einer Ursache?Diese und andere physikalische Fragen, die auch vor Relativitatstheorie und Quantenphysik nicht Halt machen, stellt der Autor sich und seinen Lesern. Auf allgemeinverstandliche Weise beantwortet er einige davon

Piotr Jakubowski is a physicist and universal philosopher who has extended his Unified Physics to a Unified Description of the entire Universe, including life and human consciousness. The Universe formula he discovered will fundamentally change all natural sciences and the technologies based on them. The Model-Naturics of the Earths climate is the only such model based on the embedding of the Solar System in its vast Cosmic Hierarchy. Reconstructing and predicting changes in the global climate over millennia is possible and reliable. The consequences of calculated changes for us humans in the near and distant future are severe.

There is a manuscript of Maharsi Bharadvaja titled Amsu-bodhini (with a commentary of Bodhananda) at the library of Oriental Institute, Vadodara (Baroda). In the introductory passages, it is said that in the original text of Bharadvaja, the aphorisms of Amsu-bodhini are divided into twelve chapters having one thousand sections. In order to make it understandable, Bodhananda wrote a commentary on it. Actually the available manuscript is the first chapter of the work, having a commentary over the first 50 aphorisms of Maharsi Bharadvdja. The title of this chapter is Srstvadhikarah i.e. the Evolution of the Universe. Description of aphorisms in first chapter describes creation of Solar system.

Per molti secoli la mano sinistra venne considerata la mano del diavolo e il mancinismo simboleggio un segno di inferiorita e devianza fino al XX secolo in Europa. Dagli anni Settanta, la percentuale dei mancini in quasi tutto il mondo e aumentata perche, tendenzialmente, non sono piu stati costretti a correggersi. Ancora oggi, tuttavia, la mano destra e associata ad attributi positivi e la mano sinistra a superstizioni o tabu. Una differente lateralizzazione degli emisferi cerebrali distingue mancini e destrorsi. Cio puo comportare sia vantaggi sia svantaggi. Questo testo e una raccolta delle conoscenze scientifiche piu recenti sul mancinismo, ma non solo. Influenze stagionali e lunari sulla fisiologia dellumana specie possono spiegare una misteriosa formula magica.

Die Physik beschreibt die Grundkrafte mit vier Wechselwirkungen, deren Ursache so genannte Bosonen sein sollen. Diese virtuellen Austausch- oder Kraftteilchen sollen sich zwischen Materieteilchen und Feldern hin und her bewegen und dabei Krafte austauschen. Die vorliegende Arbeit bezweifelt diese Vorstellung und stellt eine andere Theorie auf. Danach beruhen die fundamentalen Krafte auf dem Spin von Korpern und Systemen. Die Spin-Eigenschaften, Spin up und Spin down, von schnell rotierenden Korpern und Systemen bewirken, je nach Drehrichtung, Anziehung und Abstoung

The themes running through the book are friends and friendships. It is not an academic study of friendship. It is about the relationships with some of the people the author has encountered during his life. Readers will be able to define for themselves whom they regard as good, best, close etc. friends. This book should act as a catalyst for them to arrive at these definitions. The book shows how the class ceiling was broken by his liberal thinking parents, university education and marriage. He made deep interclass friendships. He was brought up with a live-in nanny, housekeeper, gardener etc. His mother was brought up old money and upper class in Germany. Several of his friends are professors and the human sides of these and those who taught him are demonstrated.His friendship and love of Frank, his brother, a merchant navy radio officer, resulted in his love of the sea and cruising with his parents and friends. During the pandemic lockdowns of 2020/21, his garden became a friend. His relationship with the garden was a major factor in preventing loneliness and depression. Social therapeutic gardens.A significant involvement with science in his early life supplied him with an enquiring mind and involved deep working relationships with fellow scientists. Some of the scientific work undertaken jointly with his PhD supervisor, W R Keatinge, as described. Was he a friend?Since his wife died in 2015, social media and electronic means of communicating have kept him in close touch with friends and others. The evolution and some history of these modes of communication used by the author over 50 years and are described. He was actively in politics in the earl 1980s. Political work creates friendships and camaraderie amongst campaigners.

Uber das Klima und seine Veranderung wird viel gestritten. Die einen sehen uns untergehen, andere raten zu mehr Gelassenheit. Tatsachlich ist die Entwicklung des Klimas unserer Erde eine komplexe Sache. Viele Faktoren und lange Zeitraume bestimmen die Entwicklung von Temperaturen, Niederschlagen und Klimazonen. Autor Helmut Schlafer hat auf der Suche nach einer Antwort zahlreiche wissenschaftliche Parameter zusammengetragen von Eiszeiten uber Treibhausgase und Aerosole bis zu den groen Stromungen in den Meeren und der Atmosphare sowie dem Einfluss unserer Sonne aufs Klima. So ist die Klimafibel entstanden. Sie soll anregen, sich offen und vorbehaltlos auseinanderzusetzen mit diesem komplexen Thema. Moglicherweise steht am Ende, dass wir doch nicht untergehen und es sogar Hoffnung gibt.
