Carlo Rovelli

Aika on aivan muuta kuin mitä vaistomme antaisi ymmärtää. Aika on innoittanut filosofeja ja taiteilijoita, mutta ajan synty ja suunta ovat tieteen suuria ongelmia. Aika kulkee hitaammin tai nopeammin paikasta tai nopeudesta riippuen, menneisyys ja tulevaisuus eroavat vähemmän kuin ajattelemme, eikä maailmankaikkeus piittaa nykyhetkestämme lainkaan. Ajan luonne purkaa ajan mysteeristä vyyhtiä tieteen, filosofian ja taiteen avulla. Entropiasta Einsteiniin ja kvanttiteoriaan käsityksemme ajasta on kokenut mullistuksia. Aikaa ymmärtääksemme meidän täytyy ymmärtää, miten vajavaiset aistimme ja muistimme luovat aikaa. Carlo Rovelli on kansainvälisesti arvostettu teoreettinen fyysikko. Hänen maailmanlaajuisesti yli miljoona kappaletta myynyt kirjansa, suomennettuna Seitsemän lyhyttä luentoa fysiikasta (Ursa, 2016) toi modernin fysiikan lukijoiden ulottuville eloisalla otteella.

A warning to humankind from one of the world's greatest physicists 'What drives these pages is the guilty collective conscience of my profession, theoretical physics. My sole aim is to help avert what seems to me to be the unintended, yet scarcely avoidable, end point of the current politics of the governments we have elected- nuclear war.' The world is re-arming, embroiled in endless wars. The Doomsday Clock has now been set to 85 seconds to midnight, with the risk of nuclear war the highest it has ever been. We think we understand the history of the nuclear bomb, but it is clear we have failed to learn from the past. In this urgent book, acclaimed physicist Carlo Rovelli reframes the story of nuclear weapons- from how the atomic bomb came to be to why Germany didn't build it and why the US used it when the war had been won to the narrowly averted atomic disasters of the Cold War. With lucidity and passion, he explores the many mistakes and misunderstandings that got us here, delivering a reckoning for scientists, who invented the deadliest weapon ever known, and a warning for all of us.As he grapples with the legacy of his scientific forebears, Rovelli spotlights the true nature of the decisions being made by leaders around the world today. A timely and ardent cry for peace, this searing indictment of short-sighted politics is essential reading for anyone seeking sanity at a moment of greatest peril.

The anniversary edition of the international phenomenon'One of the best books of the 21st century' (Guardian) These seven short lessons guide us, with simplicity and clarity, through the scientific revolution that shook physics in the twentieth century and still continues to shake us today. In this enchanting overview of modern physics, Carlo Rovelli explains Einstein's theory of general relativity, quantum mechanics, black holes, the complex architecture of the universe, elementary particles, gravity, and the nature of the mind.Not since Richard Feynman's celebrated Six Easy Pieces has physics been so vividly, intelligently and entertainingly revealed.

A TLS BOOK OF THE YEAR 'Anaximander is a delight and so is this book' -- James McConnachie, Sunday TimesNow widely available in English for the first time, this is Carlo Rovelli's first book: the thrilling story of a little-known man who created one of the greatest intellectual revolutions Over two thousand years ago, one man changed the way we see the world.Since the dawn of civilization, humans had believed in the heavens above and the Earth below. Then, on the Ionian coast, a Greek philosopher named Anaximander set in motion a revolution. He not only conceived that the Earth floats in space, but also that animals evolve, that storms and earthquakes are natural, not supernatural, that the world can be mapped and, above all, that progress is made by the endless search for knowledge. Carlo Rovelli's first book, now widely available in English, tells the origin story of scientific thinking: our rebellious ability to reimagine the world, again and again.Translated by Marion Lignana Rosenberg

»Jag vet inte om idén att svarta hål avslutar sin långa livstid genom att omvandlas till vita hål är korrekt. Det är det fenomen jag har studerat de senaste åren. Det involverar tiden och rummets kvantmekaniska natur, skilda perspektivs samexistens och grunden till att det förflutna skiljer sig från framtiden. Att utforska denna idé är ett äventyr som fortfarande pågår. Jag berättar det som om det vore en rapport från frontlinjen. Vad är svarta hål, som myllrar i universum? Vad är vita hål, deras svårfångade småsyskon? Och de frågor som alltid har förföljt mig: Hur förstår vi det vi aldrig har sett? Varför vill vi alltid gå vidare och se lite längre bort…?«– Carlo Rovelli

Carlo Rovellin uusin teos hahmottelee hänen teoriaansa valkoisista aukoista. Rovelli kuljettaa lukijan opastetulle kierrokselle, ensin mustan aukon tapahtumahorisontin taakse, mustan aukon nieluun, jossa ajan ja avaruuden pitäisi päättyä. Mutta Rovellin universumin versiossa näin ei tapahdu. Rovelli vie lukijansa mustan aukon sydämeen ja sitten ulos toiselle puolelle. Hän ehdottaa, että kun mustan aukon muodostava tähti jatkaa romahtamistaan, siitä tulee lopulta niin pieni ja kompakti, että yleisen suhteellisuusteorian lakien on väistyttävä kvanttimekaniikan tieltä.Tämä on kirja maallikoille ja Rovelli ymmärtää sen asettamat rajoitukset. Hän sivuuttaa yksityiskohdat välittääkseen vaikutelmia teoriastaan ja kosmoksen ytimessä olevasta hämmästyttävästä asiasta. Samalla hän esittelee omaa tutkimustyötään, sen seikkailua ja epävarmuutta ja iloa edetä tuntemattomaan. Hän kutsuu lukijan kokemaan tieteenteon kuumeen ja levottomuuden ja valkoisen aukon poikkeuksellisen elämän.

‘If you want to remember why you once fell in love with the idea of the cosmos, or want to fall in love with it for the first time, then this book is for you’ ObserverFrom Carlo Rovelli, the bestselling author of Seven Brief Lessons on Physics, this is a story of wonder, new worlds and why the end is just the beginningLet us journey into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born . . .With lightness and magic, here Carlo Rovelli traces the ongoing adventure of his own cutting-edge research, of the uncertainty and joy of going where we've not yet been. Guiding us to the edge of theory and experiment, he invites us to go beyond, to experience the fever and the disquiet of science. Here is the extraordinary life of a white hole.A BOOK OF THE YEAR ACCORDING TO THE FINANCIAL TIMES * SUNDAY TELEGRAPH * NEW STATESMAN * NEW SCIENTIST

A mesmerizing trip to the strange world of white holes from the bestselling author of Seven Brief Lessons on Physics and The Order of Time Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole's core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work. He traces the ongoing adventure of his own cutting-edge research, investigating whether all black holes could eventually turn into white holes, equally compact objects in which the arrow of time is reversed. Rovelli writes just as compellingly about the work of a scientist as he does the marvels of the universe. He shares the fear, uncertainty, and frequent disappointment of exploring hypotheses and unknown worlds, and the delight of chasing new ideas to unexpected conclusions. Guiding us beyond the horizon, he invites us to experience the fever and the disquiet of science--and the strange and startling life of a white hole.

Prominent scientists and philosophers of science address contemporary debates on the nature of Time. Their contributions freely discuss its unity and reality, its compatibility with the orders of classical philosophy (present, past and future) and with the disputed idea of free will (Volume 1). They also present a detailed and updated state of the role of Time in the so-called exact sciences: biology — or more precisely genetics, evolution, neurosciences, natural and artificial intelligence (Volume 2) , and physics — relativity, quantum mechanics and quantum gravity, and cosmology (Volume 3).
