"Szerzők sokasága vállalkozott már arra, hogy megpróbálja elmagyarázni [az egyenlet] keletkezését, legalábbis változó sikerrel. Brian Foxnál és Jeff Forshawnál alkalmasabb szerzőpárost keresve sem lehetett volna találni erre a feladatra Magas színvonalon válaszolják meg a könyv címében föltett kérdést, és elkalauzolják az olvasót a 21. századi fizika frontvonalaihoz." - (BBC Focus Magazine). - Brian Cox és Jeff Forshaw a Manchesteri Egyetemen tanítanak részecskefizikát, népszerű tudományos műsorok állandó vendégei. Könyvük afféle intellektuális kalandregény, amelyben arra vállalkoztak, hogy világos nyelven, az átlagember számára is érthetően bebizonyítsák, hogy Einstein speciális relativitáselmélete nem valamiféle misztérium, amelyet csak a tudomány fölkentjei érhetnek föl ésszel, hanem olyan mély gondolati rendszer része, amely folyamatosan alakítja az életünket. Bevezetik az olvasót a modern tudomány világába, bemutatják Einstein fölfedezésének történeti hátterét, és sok mindenről szót ejtenek, kezdve a téridő matematikai szerkezetétől az atombombáig, az asztrofizikától a Nagy Hadronütköztetőn át az anyag eredetéig. Az egyszerű dolgok alapos és részletes ismertetése mellett a tudomány szerelmeseinek is kínálnak csemegét. Sokszínű és kifejezetten olvasmányos, nagyobb részében matematikamentes barangolás a világ leghíresebb egyenlete körül.

Všichni tuto rovnici někdy viděli. Všichni znají i jejího autora. Málokdo však ví, co znamená. A ještě méně lidí chápe, jak k ní od základních fyzikálních principů dojít. Cílem této knihy je rozšířit právě tuto poslední skupinu. Text nás provází od základů klasické mechaniky a intuitivních fyzikálních a geometrických pojmů, přes teorii elektromagnetického pole, speciální a obecnou relativitu, až po standardní model částicové fyziky. Abychom pochopili obsah ústřední rovnice, musíme totiž porozumět významu jednotlivých výrazů, které v ní vystupují. Musíme vědět, co je energie, co je hmotnost a kde se bere a proč je c zrovna rychlostí světla. To vše nám kniha přístupnou formou přiblíží, současně se však autoři nezaleknou ani matematických rovnic. Zároveň ukazují čtenářům, jak se fyzikové dívají na svět. Z celé knihy je cítit radost a potěšení, které autoři zažívají při uvažování o tom, jak vlastně svět ve skutečnosti funguje; poznat je i to, že jde o zkušené vysokoškolské pedagogy, aktivní vědce a mimořádně úspěšné popularizátory v tomto oboru.

Autoři knihy Proč platí E = mc2 přicházejí s exkurzí do další oblasti moderní fyziky – do fyziky kvantové. Text postupuje historicky a připomíná nejprve klasické Newtonovy zákony. Potom se už dostáváme k radioaktivitě a otázce, co to vlastně je částice. Autoři kladou důraz na dvouštěrbinový experiment a zavedení pojmu vlnění. Komplexní vlnovou funkci a sčítání vln vysvětlují pomocí analogie s ručičkovými hodinkami nacházejícími se v každém bodě prostoru. Dostáváme tak mimo jiné i slavný Heisenbergův princip neurčitosti. Díky Pauliho vylučovacímu principu zase pochopíme stavbu atomů a princip polovodičů, a tedy i tranzistory jako základ dnešních počítačů. V závěru knihy se podíváme na standardní model částicové fyziky a skončíme Higgsovým bosonem a původem hmotnosti částic. Jako krásný příklad aplikace kvantové teorie a speciální relativity se v poslední kapitole dozvíme, co se děje, když umírá hvězda, a co po ní zůstane.

An awe-inspiring, unforgettable journey of scientific exploration from Brian Cox and Jeff Forshaw, the top ten bestselling authors of The Quantum Universe. We dare to imagine a time before the Big Bang, when the entire Universe was compressed into a space smaller than an atom. And now, as Brian Cox and Jeff Forshaw show, we can do more than imagine: we can understand. Over the centuries, the human urge to discover has unlocked an incredible amount of knowledge. What it reveals to us is breathtaking. Universal takes us on an epic journey of scientific exploration and, in doing so, reveals how we can all understand some of the most fundamental questions about our Earth, Sun, Solar System and the star-filled galaxies beyond. Some of these questions - How big is our solar system? How fast is space expanding? - can be answered from your back garden; the answers to others - How big is the Universe? What is it made of? - draw on the astonishing information now being gathered by teams of astronomers operating at the frontiers of the known universe. At the heart of all these questions - from the earliest attempts to quantify gravity, to our efforts to understand what dark matter is and what really happened at the birth of our universe - is the scientific process. Science reveals a deeper beauty, connects us to each other, to our world, and to our Universe; and, by understanding the groundbreaking work of others, reaches out into the unknown. What's more, as Universal shows us, if we dare to imagine, we can all do it.

From the bestselling authors of Why does E=mc2? comes The Quantum Universe, in which Brian Cox, presenter of the BBC's Wonders of the Solar System and Wonders of the Universe, and Jeff Forshaw go on a brilliantly ambitious mission to show that everyone can understand the deepest questions of science. But just what is quantum physics? How does it help us understand our amazing world? Where does it leave Newton and Einstein? And why, above all, can we be sure that the theory is good? Here, Brian Cox and Jeff Forshaw give us the real science behind the bizarre behaviour of the atoms and energy that make up the universe, and reveal exactly how everything that can happen, does happen.

'Inspirational' Buzz AldrinWhen exactly did life begin? What really happened during the big bang - and before it? Is the universe expanding? Is dark matter real? Do we live in one of many worlds? What's more, how can we prove any of this?This book is all about how we - any of us - can gain an understanding of the Universe in all its awe-inspiring glory. Brian Cox and Jeff Forshaw take us on an epic journey of scientific exploration, revealing how the biggest questions - from the size of the earth to the distance to the stars - are answerable from our own back gardens. You don't need a Large Hadron Collider or a Hubble Space Telescope to explore the cosmos. You just need this book.

A Brief History of Time for the 21st Century At the heart of our galaxy lies a monster so deadly, not even light can escape its grasp. Its secrets lie waiting to be discovered. It's time to explore our universe's most mysterious inhabitants Black Holes At the heart of the Milky Way lies a supermassive black hole 4 million times more massive than our Sun. A place where space and time are so warped that light is trapped if it ventures within 12 million km. According to Einstein, inside lies the end of time. According to 21st-century physics, the reality may be far more bizarre. Black holes lie where the most massive stars used to shine and at the edge of our current understanding. They are naturally occurring objects, the inevitable creations of gravity when too much matter collapses into not enough space. And yet, although the laws of nature predict them, they fail fully to describe them. Black holes are places in space and time where the laws of gravity, quantum physics and thermodynamics collide. Originally thought to be so intellectually troubling that they simply could not exist, it is only in the past few years that we have begun to glimpse a new synthesis; a deep connection between gravity and quantum information theory that describes a holographic universe in which space and time emerge from a network of quantum bits, and wormholes span the void. In this groundbreaking book, Professor Brian Cox and Professor Jeff Forshaw take you to the edge of our understanding of black holes; a scientific journey to the research frontier spanning a century of physics, from Einstein to Hawking and beyond, that ends with the startling conclusion that our world may operate like a giant quantum computer.

What does E=mc2 actually mean? Dr. Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of twenty-first century science to unpack Einstein's famous equation. Explaining and simplifying notions of energy, mass, and light-while exploding commonly held misconceptions-they demonstrate how the structure of nature itself is contained within this equation. Along the way, we visit the site of one of the largest scientific experiments ever conducted: the now-famous Large Hadron Collider, a gigantic particle accelerator capable of re-creating conditions that existed fractions of a second after the Big Bang. A collaboration between one of the youngest professors in the United Kingdom and a distinguished popular physicist, Why Does E=mc2? is one of the most exciting and accessible explanations of the theory of relativity.
