Sky Colors

Science & Nature

"Sky Colors" explores the captivating science behind the ever-changing colors of the sky, from the familiar daytime blue to the vibrant hues of sunset. The book delves into the fundamental principles of atmospheric science, meteorology, and Earth sciences to explain these optical phenomena. One intriguing insight is how Rayleigh scattering, the selective scattering of sunlight by atmospheric particles, is most effective at shorter wavelengths, resulting in the blue sky we see when the sun is high. As the sun sets, its light travels through more of the atmosphere, scattering away the blue and leaving the longer wavelengths of red and orange to dominate. The book systematically builds upon core concepts, beginning with the physics of light and atmospheric composition, then delving into Rayleigh scattering and its dependence on wavelength and particle size. It also explores how atmospheric conditions, such as humidity and pollution, can modify the scattering process and impact sky color. This approach emphasizes scientific reasoning and the link between theoretical predictions and real-world observations.Finally, "Sky Colors" connects these scientific principles to broader environmental phenomena, such as air quality monitoring and climate change, demonstrating the interdisciplinary nature of this captivating subject. By understanding the science of sky colors, readers can gain a deeper appreciation for the natural world and its intricate processes.

C'è qualcuno là fuori?

Science & Nature

C'è qualcuno là fuori, oltre i confini del Sistema solare, alle estremità della nostra galassia, nello spazio intergalattico? Considerando l'esperienza e i dati osservativi, dovremmo concludere che nell'universo siamo soli, eppure da parecchi millenni gli uomini popolano il cielo di figure bizzarre, omini verdi e dischi volanti che cambiano aspetto a seconda della cultura e del gusto dell'epoca. E, come si scopre in questo libro, tra gli sponsor degli alieni non ci sono soltanto visionari e scrittori fantasiosi, ma anche illustri scienziati come Keplero, al quale si deve la scoperta delle leggi che regolano i movimenti dei pianeti e pure una descrizione particolareggiata dell'aspetto dei seleniti e delle città lunari! Per i sostenitori della fantarcheologia, poi, l'inseguimento dei nostri fratelli spaziali è un'ossessione che ha portato a vedere «prove» del passaggio di alieni sulla Terra tra i graffiti delle caverne o le figure scolpite su antichissimi monumenti: nelle loro congetture, tanto suggestive quanto strampalate, gli extraterrestri avrebbero eretto piramidi un po' ovunque, dall'Egitto al Messico, costruito le enormi statue di pietra dell'Isola di Pasqua e trasmesso ai nostri antenati i rudimenti della civiltà. In un racconto disseminato di curiosità e di rivelazioni sorprendenti e arricchito da singolari immagini, gli autori ripercorrono la lunga storia della ricerca di altri esseri intelligenti e interrogano la scienza sull'enigma della pluralità dei mondi, consapevoli che, malgrado nessuno conosca la risposta, la domanda è fra quelle più affascinanti di sempre. Una domanda cui Margherita Hack ha voluto dedicare i suoi ultimi mesi di lavoro.

Jenseits von Freiheit und Würde

Science & Nature

In seinem höchst beunruhigenden und provokativen Buch hat B. F. Skinner aus Methoden und Resultaten seiner jahrzehntelangen Forschungsarbeit die Summe gezogen und darauf eine Analyse von Zustand und Zukunft der Gesellschaft und des einzelnen Menschen aufgebaut. Die Krise, in der sich die Weltzivilisation befindet, kann nur überwunden werden, wenn das Verhalten des Menschen von Grund auf neu motiviert wird. Die einzige Überlebenschance sieht Skinner in einer radikalen Revision der geheiligten Ideale von Freiheit und Würde. Diese machtvoll wirksamen Wertvorstellungen haben in der Geschichte stets eine wesentliche Rolle gespielt beim Kampf des Menschen gegen Tyrannei, Despotie und andere Formen autoritärer Herrschaft. Obwohl Skinner ihre wichtige historische Funktion durchaus sieht, gibt er den nahezu religiös verehrten Dogmen von Freiheit und Würde die Hauptschuld an dem gefährlichen Götzenkult, in welchem mittlerweile der Idee vom autonomen Menschen gehuldigt wird. Freiheit und Würde sind Tabus, ihre kritiklose Verinnerlichung hat schwerwiegende Folgen, vor allem weil sie uns an der hergebrachten Bestrafungsethik festhalten lassen und so die Entwicklung einer effektiveren kulturellen Praxis vereiteln.

Il lungo racconto dell'origine

Science & Nature

La cosmologia moderna è oggi una grande scienza, supportata da fisica, matematica e tecnologie costosissime, che sembra schiuderci i segreti dell'Infinito. Ma le domande e le spiegazioni sull'origine e la natura dell'universo sono vecchie quanto l'uomo. Dai babilonesi ai cinesi e i maya, caste di sacerdoti-astronomi usavano le sorprendenti conoscenze sui movimenti degli astri per sostenere il loro potere, ricorrendo spesso a miti fantasiosi. Furono greci i primi astronomi-filosofi con metodi di calcolo rigorosi. Con il Cristianesimo, per secoli gli astri sono stati espressione di Dio. E solo da Galileo ad oggi, la scienza ha faticosamente affrancato l'indagine sul cosmo dai diktat della religione. In ogni caso, dai miti più ingenui alle teorie scientifiche più ardite, quello dell'universo resta il racconto più affascinante che ha accompagnato l'evoluzione culturale dell'uomo. Questo libro ripercorre le cosmologie delle grandi civiltà. Una grande avventura della ragione, dal mito alla scienza, attraverso cui è cresciuta la nostra conoscenza dei misteri della vita.

El punto crucial

Science & Nature

Juntos estamos avanzando a gran velocidad por el carril rápido de una autopista que cruza la frontera de las creencias tradicionales, las religiones y los hábitos del pasado. Al hacerlo, estamos consiguiendo que desaparezcan los límites de lo que en su día pensábamos que era imposible. Estas experiencias tan importantes son nuestro pasaporte de entrada a un nuevo mundo que emerge ante nuestros ojos.Entre las muchas incertidumbres que traen, sin embargo, hay una cosa que podemos saber con absoluta certeza: nuestras vidas están cambiando de tal manera y a tanta velocidad que no estamos preparados para ello. Y el mundo que veo emerger es un mundo donde la guerra ha quedado obsoleta y donde el uso de amenazas para solventar nuestros problemas ya no tiene sentido. Un mundo donde el deseo de cooperación es mayor que el miedo que nos conduce a la compentencia violenta. Y también veo un cambio en nuestra manera de pensar que hace de todo esto algo verdaderamente posible. Sin embargo, para lograr ese cambio, antes debemos empezar a reconocer las realidades que tenemos ante nosotros así como la promesa que éstas esconden. Un buen punto de partida es agradecer el hecho de estar viviendo en una época de extremos.

Notte di stelle

Science & Nature

La notte stellata non è solo uno spettacolo affascinante, ma lo spazio sterminato nel quale sono scritte migliaia di scoperte scientifiche e di antiche storie. I nostri antenati hanno trovato nel cielo le conoscenze più utili alla sopravvivenza: hanno imparato a orientarsi in mare o nei deserti, a costruire orologi e calendari, a sfruttare i cicli stagionali per i lavori dei campi. Incantati dai movimenti degli astri e dei pianeti, intimoriti dalle eclissi o dalle comete, hanno anche popolato il firmamento di dèi ed eroi che ne spiegassero il mistero. Oggi l'osservazione scientifica degli oggetti celesti ci ha permesso di apprendere molte cose intorno alla nascita e alla vita dell'universo e della Terra. In un percorso che tocca l'astronomia e l'archeologia, la scienza e il mito, gli autori ci insegnano a «leggere» il cielo notturno: partendo dalle costellazioni, visibili a occhio nudo e ben riconoscibili, Margherita Hack spiega la formazione e la struttura delle stelle e i fenomeni astronomici che vi sono legati, accompagnandoci attraverso galassie, buchi neri e nebulose. Viviano Domenici racconta le leggende e i miti legati alle stelle nelle differenti culture, raccogliendo notizie e curiosità dalle cosmogonie, dall'archeologia, dall'arte e dalla letteratura di tutti i tempi e di tutti i Paesi. Una lettura avvincente tra i segreti, i sogni e le paure degli antichi che hanno riposto fra gli astri più brillanti le loro favole più belle rendendole immortali.

Zeitbewusstheit

Science & Nature

Den Zeitraum von neun Tagen, den ein Tropfen Wasser durchschnittlich in der Atmosphäre verbleibt, können wir leicht nachvollziehen. Aber die Hunderte von Jahren, die sich ein Molekül Kohlendioxid, das den Klimawandel antreibt, darin erhält, überschreiten die Grenzen unserer Vorstellung. Doch gerade die Prozesse, die weit vor uns lagen, prägen unsere Gegenwart, und unser heutiges Verhalten wird noch über Generationen hinweg gravierende Folgen für den Zustand der Erde haben. In Zeitbewusstheit zeigt Marcia Bjornerud eindrucksvoll, wie die Geologie als Biografin unseres Heimatplaneten anhand der Messungen von Erosion und Gebirgsbildung, aber auch von Ozean- und Atmosphärenveränderungen ein Verständnis für die Tiefenzeit und den Rhythmus der Erde bereithält, das wir in unserer Epoche der Beschleunigung dringend brauchen, wenn wir Lösungen für die drohende Umweltkatastrophe finden wollen. Die Lebensdauer der Erde mag im Vergleich zu der eines Menschen ewig erscheinen, doch zur Sicherung des Überlebens beider bleibt uns in Wirklichkeit nur wenig Zeit.

Climate Change, Environmental Refugees, and Human Rights in the Middle East

Science & Nature

This in-depth and readable text introduces students to the current and historical impacts of climate change on the region. The Middle East and North Africa (MENA) region has experienced more frequent droughts, heat waves, and other extreme weather events than the rest of the world. Flooding has forced human migration and displacement in Egypt, Iran, and Tunisia in 2020, while wildfires have spread in Lebanon, Syria, and Turkey. The author, a specialist in the MENA region, unpacks the implications of several developments that have triggered large-scale migration from rural to urban areas in the Middle East, and North Africa, and threaten to destabilize the region. These include, among other things, widespread famine, population displacement, and the growing decline of agricultural productivity. Digging deep into key terminology and frameworks such as the 1951 Refugee Convention, climate–human rights nexus, climate-related protest, environmental politics, green investment, and climate governance, the author demonstrates how human rights and climate change are inextricably intertwined and provides additional context to support student learning. This book examines the environmental threats and history of individual countries, including a survey of how the issues of climate change, forced migration, and human rights interface with socioeconomic, political, and legal perspectives.
