Démon a gépezetben
Amikor Darwin elhatározta, hogy megmagyarázza a fajok eredetét, meg sem próbált arra a mélyebb kérdésre válaszolni, hogy mi az élet. A tudósok generációkon át küzdöttek azért, hogy megértsék ezt az alapvető problémát. Az élet tényleg varázslatnak látszik: még egy egyszerű baktérium is olyan káprázatos dolgokat visz véghez, hogy nincs az a mérnök, akinek az alkotása felvehetné vele a versenyt. Mindamellett, a molekuláris biológia elmúlt évtizedekben elért eredményei csak elmélyítették a rejtélyt. Megmagyarázható-e az élet a ma ismert fizika és kémia keretein belül, vagy valamilyen alapvetően új megközelítésre van szükség? Ebben az elmélyült és átfogó, új elemzésében a fizikus és tudománynépszerűsítő Paul Davies egy olyan új és gyorsan fejlődő tudományterületen keresi a választ, amelynek még neve sincs, de kiterjed az informatika, a kémia, a kvantumfizika és a nanotechnológia felségvizeire. A Démon a gépezetben lélegzetelállító utazás a fizika, a biológia, a logika és a számítástechnika birodalmában, az élet homályba merülő kezdeteitől azokig a mikroszkopikus gépecskékig, amelyek sejtjeinket működtetik. Miután összekapcsolja a rákot a tudatossággal és a kétfejű férgeket a madarak tájékozódásával, Davies felismeri, miként gyűjtik össze és dolgozzák fel az információt a biológiai szervezetek, hogy rendet teremtsenek a káoszból, miáltal betekintést engednek magának az életnek a titkaiba.

How to Make an Apple Pie from Scratch
We probably all have a vague idea of how to make an apple pie: mix flour and butter, throw in some apples and you're probably most of the way there, right? Think again. Making an apple pie from scratch requires ingredients that definitely aren't available in the supermarket, ovens that can reach temperatures of trillions of degrees, and a preparation time of 13.8 billion years.
Inspired by Sagan's famous line, Harry Cliff ventures out in search of the ultimate apple pie recipe, tracing the ingredients of our universe through the hearts of dying stars and back in time to a tiny fraction of a second after our universe began. Along the way, he confronts some really big questions: What is matter really made of? How does the stuff around us escape annihilation in the fearsome heat of the Big Bang? And will we ever be able to understand the very first moments of our universe?
In pursuit of answers, Cliff ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the 'Antimatter Factory' where this stuff of science fiction is manufactured daily (and we're close to knowing whether it falls upwards). And he reveals what the latest data from the Large Hadron Collider may be telling us about the fundamental ingredients of matter.
Along the way, Cliff illuminates the history of physics, chemistry, and astronomy that brought us to our present understanding of the world, while offering readers a front-row seat to one of the most dramatic intellectual journeys human beings have ever embarked on.
A transfixing deep dive into origins of our world, How to Make an Apple Pie from Scratch doesn't just put the makeup of our universe under the microscope, but the awe-inspiring, improbable fact that it exists at all.
'A fascinating exploration of how we learned what matter really is, and the journey matter takes from the Big Bang, through exploding stars, ultimately to you and me.' - Sean Carroll, author of Something Deeply Hidden
'If you wish to make an apple pie from scratch, you must first invent the universe.' - Carl Sagan
The Sirens of Mars
As a new wave of interplanetary exploration unfolds, a talented young planetary scientist charts our centuries-old obsession with Mars.
'Beautifully written, emotive - a love letter to a planet' DERMOT O'LEARY, BBC Radio 2
Mars - bewilderingly empty, coated in red dust - is an unlikely place to pin our hopes of finding life elsewhere. And yet, right now multiple spacecraft are circling, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium and Mare Sirenum - on the brink, perhaps, of a discovery that would inspire humankind as much as any in our history.
With poetic precision and grace, Sarah Stewart Johnson traces the evocative history of our explorations of Mars. She interlaces her personal journey as a scientist with tales of other seekers - from Galileo to William Herschel to Carl Sagan - who have scoured this enigmatic planet for signs of life and transformed it in our understanding from a distant point of light into a complex world. Ultimately, she shows how its story is also a story about Earth: it is a foil, a mirror, a tell-tale reflection of our own anxieties and yearnings to find - if we're lucky - that we're not alone.

Stručná historie času
Ve své Stručné historii času Stephen Hawking přístupně a čtivě rekapituluje vědecké i předvědecké názory na vznik a podobu vesmíru. Od mytologických představ o Zemi ležící na krunýři želvy se přes heliocentrické a geocentrické modely Sluneční soustavy dostává k Albertu Einsteinovi a jeho převratným objevům dotýkajícím se povahy prostoru a času. Shrnuje neuvěřitelný pokrok, jaký věda v poznávání vesmíru učinila ve dvacátém století, a dostává se až na práh objevu teorie všeho, která by sjednotila dosavadní fyzikální poznatky do komplexního celku a která prozatím zůstává nedosažitelná.

The End of Everything
We know the universe had a beginning. But what happens at the end of the story?
With lively wit and wry humour, astrophysicist Katie Mack takes us on a mind-bending tour through each of the cosmos' possible finales: the Big Crunch, Heat Death, Vacuum Decay, the Big Rip and the Bounce. Guiding us through major concepts in quantum mechanics, cosmology, string theory and much more, she describes how small tweaks to our incomplete understanding of reality can result in starkly different futures. Our universe could collapse in upon itself, or rip itself apart, or even - in the next five minutes - succumb to an inescapable expanding bubble of doom.
This captivating story of cosmic escapism examines a mesmerizing yet unfamiliar physics landscape while sharing the excitement a leading astrophysicist feels when thinking about the universe and our place in it. Amid stellar explosions and bouncing universes, Mack shows that even though we puny humans have no chance of changing how it all ends, we can at least begin to understand it.
The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know.
Fekete lyukak
„Azt tartják, a tények néha furcsábbak a fantázia szüleményeinél, és ez sehol másutt nem igaz annyira, mint a fekete lyukak esetében. A fekete lyukak különösebbek, mint bármi, amit csak a tudományos-fantasztikus írók megálmodtak.” Stephen Hawking professzor 2016-ban két előadást tartott a BBC Reith-előadássorozatában, arról a témáról, amelyik már évtizedek óta foglalkoztatja őt – a fekete lyukakról. A legendás fizikus ebben a két, maradandó élményt adó előadásában kifejti, hogy csak akkor juthatunk közelebb az univerzum titkainak feltárásához, ha megértjük a fekete lyukakat és azt a kihívást, amelyet ezek az objektumok a tér és az idő természetére vonatkozóan jelentenek.
Reimagining Time: A Light-Speed Tour of Einsteins Theory of Relativity
It was a link to Albert Einstein's 1905 paper-an early attempt at explaining his revolutionary ideas on space, time, and matter-that drew Tanya Bub into his imaginative vision of the world. What particularly struck her was how Einstein interwove words and math to create clear visuals illustrating his theories. As an artist, she naturally started doodling as she worked her way through his concepts, creating drawings that intuitively demonstrated Einstein's core principles.
In Reimagining Time, Tanya Bub teams up with her father, the distinguished physicist Jeffrey Bub, to create a quirky and accessible take on one of science's most revolutionary discoveries. Blending original art and text, they guide readers-even nonmathematicians-through Einstein's theory of special relativity to reveal truths about our universe: time is relative, lengths get shorter with motion, energy and mass are interchangeable, and the universe has a speed limit.
A quirky, funny, and accessible blend of science and art that delves into the heart of Einstein's theory of relativity
"A fascinating introduction to the core concepts of special relativity. The unique illustrated format and elegant writing will appeal to readers who have not encountered these ideas before."-Chad Orzel, author of How to Teach Quantum Physics to Your Dog

Ironický humor, anekdoty ze života, jednoduché a názorné obrázky, ale především spousta dobře dávkovaných znalostí uvádí čtenáře téměř bezbolestně do fascinujícího světa moderní vědy.
Light in the Darkness
For readers of Stephen Hawking, a fascinating account of the universe from the perspective of world-leading astrophysicist Heino Falcke, who took the first ever picture of a black hole.
10th April 2019: a global sensation. Heino Falcke, a man "working at the boundaries of his discipline and therefore at the limits of the universe" had used a network of telescopes spanning the entire planet to take the first picture of a black hole.
Light in the Darkness examines how mankind has always looked to the skies, mapping the journey from millennia ago when we turned our gaze to the heavens, to modern astrophysics. Heino Falcke and Jorg Romer entertainingly and compellingly chart the breakthrough research of Falcke's team, an unprecedented global community of international colleagues developing a telescope complex enough to look directly into a black hole - a hole where light vanishes, and time stops.
What does this development mean? Is this the beginning of a new physics? What can we learn from this about God, the world, and ourselves? For Falcke, astrophysics and metaphysics, science and faith, do not exclude one another. Black Hole is both a plea for curiosity and humility; it's interested in both what we know, and the mysteries that remain unsolved.
History of the Universe in 100 Stars
From the Big Bang to the Gaia Mission, this is a very personal history of the universe through the author's favourite 100 stars.
Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights. And Gamma Draconis, from which we know that the earth rotates around its own axis. There is also the star sequence 61 Cygni, which revealed the size of the cosmos to us.
Then there are certain stars used by astronomers to search for extra-terrestrial life, to explore interstellar space travel, or to explain why the dinosaurs became extinct.
In 100 short, fascinating and entertaining chapters, Freistetter not only reveals the past and future of the cosmos, but also the story of the people who have tried to understand the world in which we live.
Something Deeply Hidden Quantum Worlds and the Emergence of Spacetime
'An authoritative and beautifully written account of the quest to understand quantum theory and the origin of space and time.' Professor Brian Cox
Quantum physics is not mystifying. The implications are mind-bending, and not yet fully understood, but this revolutionary theory is truly illuminating. It stands as the best explanation of the fundamental nature of our world.
Spanning the history of quantum discoveries, from Einstein and Bohr to the present day, Something Deeply Hidden is the essential guide to the most intriguing subject in science. Acclaimed physicist and writer Sean Carroll debunks the myths, resurrects and reinstates the Many-Worlds interpretation, and presents a new path towards solving the apparent conflict between quantum mechanics and Einstein's theory of general relativity. In doing so, he fills a gap in the science that has existed for almost a century.
A magisterial tour, Something Deeply Hidden encompasses the cosmological and everyday implications of quantum reality and multiple universes. And - finally - it all makes sense.
The God Equation
From the international bestselling author of Physics of the Impossible and Physics of the Future
This is the story of a quest: to find a Theory of Everything. Einstein dedicated his life to seeking this elusive Holy Grail, a single, revolutionary 'god equation' which would tie all the forces in the universe together, yet never found it. Some of the greatest minds in physics took up the search, from Stephen Hawking to Brian Greene. None have yet succeeded.
In The God Equation, renowned theoretical physicist Michio Kaku takes the reader on a mind-bending ride through the twists and turns of this epic journey: a mystery that has fascinated him for most of his life. He guides us through the key debates in modern physics, from Newton's law of gravity via relativity and quantum mechanics to the latest developments in string theory. It is a tale of dazzling breakthroughs and crushing dead ends, illuminated by Kaku's clarity, storytelling flair and infectious enthusiasm.
The object of the quest is now within sight: we are closer than ever to achieving the most ambitious undertaking in the history of science. If successful, the Theory of Everything could simultaneously unlock the deepest mysteries of space and time, and fulfil that most ancient and basic of human desires - to understand the meaning of our lives.

The Contact Paradox
In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilisations to our existence. Of course, we don't know if such civilisations really exist. For the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence. So far, SETI has found no evidence of extraterrestrial life, but with more than a hundred billion stars in our Galaxy alone to search, the odds of quick success are stacked against us.
The silence from the stars is prompting some researchers to transmit more messages into space, in an effort to provoke a response from any civilisations out there that might otherwise be staying quiet. However, the act of transmitting raises troubling questions about the process of contact.
In The Contact Paradox, author Keith Cooper looks at how far SETI has come since its modest beginnings, and where it is going, by speaking to the leading names in the field and beyond. SETI forces us to confront our nature in a way that we seldom have before - where did we come from, where are we going, and who are we in the cosmic context of things? This book considers the assumptions that we make in our search for extraterrestrial life, and explores how those assumptions can teach us about ourselves.
Genesis
What if the ancient Greeks were right, and the universe really did spring into being out of chaos and the void? How could we know? And what must its first moments have been like?
To answer these questions, scientists are delving into all the hidden crevices of creation. Armed with giant telescopes and powerful particle accelerators, they probe the subtle mechanisms by which our familiar world came to be, and try to foretell the manner in which it will end.
The result of all this collective effort is a complex tale, stranger at times than even our most ancient creation myths. Yet its building blocks give us the power to work marvels our predecessors could scarcely comprehend. In Genesis, the CERN physicist and bestselling author Guido Tonelli does poetic justice to that great story, the accomplishment of countless minds working together across the ages.
