Jak Henrietta Leavittová a Edwin Hubble bilionkrát zvětšili vesmír. Běžně dnes uvádíme, že ta a ta hvězda či mlhovina je od nás vzdálena tolik a tolik světelných let. Jak jsme ale na tato čísla přišli? Kniha nás provede od prvních pokusů o určování vzdáleností Slunce a Měsíce, které podnikli antičtí astronomové, až po moderní velikány astronomie, jako byl Edwin Hubble. V jejím centru ovšem stojí téměř zapomenutý příběh ženy, která na počátku 20. století objevila jeden z významných zákonů umožňujících měřit vesmír – Henrietty Swan Leavittové.

Cesta ke kvantovému počítači. Jestliže se vědcům a technikům podaří postavit kvantový počítač, zažije informatika snad největší revoluci od svého vzniku v polovině 20. století. Výpočetními elementy takového stroje budou nepatrné objekty, atomy či ještě menší částice, pro něž neplatí běžná fyzikální pravidla, ale zdánlivě bizarní zákony kvantové mechaniky. V principu by pak mohlo pár desítek důmyslně propojených atomů paralelně provádět mnohem složitější výpočty než nejmodernější superpočítače dneška. Autor v knize zasvěceně a přitom zcela srozumitelně objasňuje teoretickou koncepci kvantového počítání, jeho základní algoritmy i první pokusy tuto fascinující myšlenku prakticky realizovat.

In a series of personal essays, prominent journalist and LGBTQIA+ activist George M. Johnson explores his childhood, adolescence, and college years in New Jersey and Virginia. From the memories of getting his teeth kicked out by bullies at age five, to flea marketing with his loving grandmother, to his first sexual relationships, this young-adult memoir weaves together the trials and triumphs faced by Black queer boys. Both a primer for teens eager to be allies as well as a reassuring testimony for young queer men of color, All Boys Aren't Blue covers topics such as gender identity, toxic masculinity, brotherhood, family, structural marginalization, consent, and Black joy. Johnson's emotionally frank style of writing will appeal directly to young adults.

"No scientist has done more to shape our understanding of the universe than Murray Gell-Mann, the Nobel Prize-winner considered by many colleagues to be the most brilliant physicist of his generation. His discovery of the quark and the Eightfold Way were cornerstones for all that followed in particle physics, the effort to understand the very stuff of creation, In this, the first biography of Gell-Mann, George Johnson tells the story of a remarkable life."

When the woman he loved was diagnosed with metastatic cancer, science-writer George Johnson embarked on a journey to learn everything about the disease and those dedicated to combating it. He discovered a revolution in understanding cancer, revealing an explosion of new ideas about its nature and origins. Johnson explores epidemiology, clinical trials, laboratory experiments, and scientific hypotheses to uncover what we know and don’t know about cancer, explaining why a cure remains elusive. His vivid accounts describe tumors evolving like alien creatures, paleo-oncologists finding petrified tumors on dinosaur and ancient human skeletons, and surprising shifts in scientific understanding regarding cancer's causes, with diet and environmental toxins playing a lesser role than previously thought. Most intriguingly, he reveals how cancer hijacks natural processes involved in healing wounds and human embryonic development, turning them against the body. Throughout his exploration, Johnson captures the human experience with poignant grace, documenting the arduous journey of consultations, surgeries, targeted therapies, and other treatments. Provocative and intellectually vibrant, this work challenges preconceived notions about cancer while offering hope for the future.

First paperback edition of the illustrated history of the hundred greatest American football players of all time who have captivated millions of fans of the National Football League worldwide.

Are there really laws governing the universe? Or is the order we see a mere artifact of the way evolution wired the brain? And is what we call science only a set of myths in which quarks, DNA, and information fill the role once occupied by gods? These questions lie at the heart of George Johnson's audacious exploration of the border between science and religion, cosmic accident and timeless law. Northern New Mexico is home both to the most provocative new enterprises in quantum physics, information science, and the evolution of complexity and to the cosmologies of the Tewa Indians and the Catholic Penitentes. As it draws the reader into this landscape, juxtaposing the systems of belief that have taken root there, Fire in the Mind into a gripping intellectual adventure story that compels us to ask where science ends and religion begins. "A must for all those seriously interested in the key ideas at the frontier of scientific discourse."--Paul Davies

Während Sie diese Worte lesen, verändert sich ein winziger Teil Ihres Gehirns physisch. Neue Verbindungen entstehen – ein Schaltkreis, der ein Gefühl der Wiedererkennung erzeugt, wenn Sie die Worte erneut begegnen. Das ist eine der Theorien des Gedächtnisses, die in diesem faszinierenden und hervorragend lesbaren Buch vorgestellt wird, das die Untersuchungen dreier Forscher zu den Prozessen destilliert, die es uns ermöglichen, ein Gesicht zu erkennen, das zehn Jahre älter geworden ist, oder eine Melodie über Jahrzehnte hinweg zu erinnern. Von Experimenten, die am "Wetware" des Gehirns durchgeführt werden, bis hin zu Versuchen, menschliche Kognition in Computern nachzubilden, ist In den Palästen der Erinnerung Wissenschaftsschreiben in seiner aufregendsten Form.
