We take time for granted as it passes during every moment of our existence. Other things may change, but time remains constant and predictable. The past, the present, and the future exist within a harmonious, reliable, and never-changing system. Or at least that’s how it seems. It was Albert Einstein who, in 1905, first theorized that time might not be quite as straightforward as that. In one of the most influential papers on physics ever published[1], he proposed something called “time dilatation.”

The most authoritative philosophers and historians of science agree in stating that the Copernican revolution did not originate from astronomical motivations but from ideological reasons. Both Copernicus and Galileo shared the Pythagorean doctrine, with an anti-Christian background, even before developing the shaky astronomical model that symbolized it. So, if scientific reasons were not what led to the birth and dominance of the heliocentric model, to what extent does the idea of the Earth's movement correspond to reality?

People often think of imagination as something used only in creative endeavours. In fact, we use imagination constantly as we reminisce, anticipate, plan, daydream, read, create imagined worlds. The truth is we live in the here and now much less than we tend to think. Imagination isn’t the exception in our daily lives; it’s our default setting. Yet only now are we beginning to understand exactly how it works. From hallucination to sleepwalking, from REM sleep to delusions, neurologist Adam Zeman brilliantly guides us through the latest scientific studies in the world of the imagination.

After the extinction of the dodo and Carolina parakeet and the collapse of the American bison population, naturalists expected many more vulnerable species to die out with spread of industrialization. This triggered a race to collect rare species of animals expected soon to be lost forever. Established in 1893, Chicago's Field Museum aimed to become a global center of study. Zoologist Daniel Giraud Elliot persuaded museum patrons to fund an immediate expedition to British Somaliland (contemporary Somalia). There, his team hunted and killed hundreds of animals for the growing collection.

19 aprile 1943. Albert Hofmann, chimico in forze all'azienda farmaceutica Sandoz di Basilea, inforca la bicicletta e si avvia verso casa. Sembra un giorno come un altro, se non fosse che ha appena assunto 250 microgrammi di dietilammide-25 dell'acido lisergico, un composto da lui stesso sintetizzato nella ricerca di uno stimolante della circolazione sanguigna. Ciò che accade durante il tragitto sconvolge la sua nozione del reale: visioni coloratissime, meravigliose e mostruose, percezioni di realtà parallele, terrori, euforie. È nato l'Lsd.

Oggi sappiamo che l’universo ha avuto origine con un big bang e si è espanso sotto il controllo delle componenti oscure di materia ed energia; abbiamo imparato come si formano, evolvono e interagiscono le galassie, e come nascono, vivono e muoiono le stelle; abbiamo cercato i pianeti extrasolari e i segnali della vita, ascoltato l’urlo della fusione di due buchi neri e molto altro ancora. Un sapere frutto del balzo in avanti dell’astrofisica e della cosmologia nel Novecento, stimolato e secondato dai grandiosi progressi della fisica e dalla tecnologia.

An unbelievable series of events led to the establishment of the Northwest Electro-development Laboratory, later the U.S. Bureau of Mines Albany Research Center. Though the fledgling lab had difficulty securing staff due to World War II, world-renown metallurgist William J. Kroll was hired early on as a consultant after fleeing Nazi occupation. Kroll, who had pioneered a method for producing commercial titanium, worked with his core group of associates to develop malleable zirconium, just as a need arose for the little-known metal.

In the mid-1800s a dreaded illness swept through the tropical regions of the globe. Malaria was a prevalent and often deadly parasite. It caused fever, chills, headaches, even confusion, seizures, and sometimes death. A cure needed to be found but this quest would lead to an unexpected discovery.

In Charged, James Morton Turner unpacks the history of batteries to explore why solving "the battery problem" is critical to a clean energy transition. As climate activists focus on what a clean energy future will create the history of batteries offers a sharp reminder of what building that future will consume. With new insight on the consequences for people and communities on the front lines, Turner draws on the past for crucial lessons that will help us build a just and clean energy future, from the ground up.

How many times have we looked for something and found something else? A partner, a job, an object? The same thing often happens to scientists: they design an experiment and discover the unexpected, which usually turns out to be very important. This fascinating phenomenon is called serendipity, which takes its name from the mythical Serendip, a place from which, according to a Persian fable, three princes set off to explore the world, making chance discoveries along the way.

Il settore dei trasporti, in particolare quello su strada, è responsabile di un quarto delle emissioni di gas serra e i combustibili fossili che utilizza producono sostanze tossiche per l’uomo e per l’ambiente, oltre a essere soggetti a oscillazioni di prezzo per ragioni geopolitiche. La mobilità elettrica sta emergendo negli ultimi anni per dare una risposta efficace a questi e altri problemi, nella prospettiva di un pianeta sempre più decarbonizzato secondo gli obiettivi già stabiliti dai governi e dai trattati internazionali.
