Jest to druga część doskonałego podręcznika nowoczesnej kwantowej teorii pola
(niemal klasycznej już dziedziny fizyki teoretycznej) napisanego przez
znakomitego fizyka i dydaktyka Stevena Weinberga. W ciągu ostatnich kilkunastu
lat kwantowa teoria pola ulegała licznym przeobrażeniom, lecz niewątpliwie
stała się przy tym teorią efektywną - słuszną dla zjawisk pojawiających się w
zakresie energii dostępnych obecnie eksperymentatorom. Metody kwantowej teorii
pola są i pozostaną jeszcze przez wiele lat podstawowym narzędziem fizyków
zajmujących się nie tylko kwantową teorią pola i fizyką cząstek elementarnych,
ale również materią skondensowaną.

One of the world's most captivating scientists challenges us to think about
nature's foundations and the entanglement of science and society. Steven
Weinberg, author of The First Three Minutes, offers his views on fascinating
aspects of physics and the universe, but does not seclude science behind
disciplinary walls, or shy away from politics.
Kniha Ako vysvetliť svet je fascinujúcou správou o tom, ako dejiny fyziky ovplyvnili naše uvažovanie a vývoj ľudstva.
Nositeľ Nobelovej ceny za fyziku Steven Weinberg, sprevádza čitateľov od antického Milétu cez stredoveký Oxford a katedrálnu školu v Chartres až po najnovšie výskumy v CERN-e. Ukazuje, že antickí a stredovekí bádatelia nielenže nevedeli o svete to, čo vieme dnes, ale ani nechápali, čo znamená svetu rozumieť alebo ako toto pochopenie dosiahnuť. Weinberg skúma historické zápasy i spoluprácu fyziky so súperiacimi oblasťami – náboženstvom, technikou, poéziou, matematikou a filozofiou.
Publikácia sprostredkúva pohľad súčasného vedca na prácu svojich predchodcov a objasňuje, akú dlhú a náročnú cestu prešla fyzika, kým sa stala vedou, ako ju poznáme dnes.
Just as Henry David Thoreau “traveled a great deal in Concord,” Nobel Prize–winning physicist Steven Weinberg sees much of the world from the window of his study overlooking Lake Austin. In Lake Views Weinberg, considered by many to be the preeminent theoretical physicist alive today, continues the wide-ranging reflections that have also earned him a reputation as, in the words of New York Times reporter James Glanz, “a powerful writer of prose that can illuminate—and sting.” This collection presents Weinberg’s views on topics ranging from problems of cosmology to assorted world issues—military, political, and religious. Even as he moves beyond the bounds of science, each essay reflects his experience as a theoretical physicist. And as in the celebrated Facing Up , the essays express a viewpoint that is rationalist, reductionist, realist, and secular. A new introduction precedes each essay, explaining how it came to be written and bringing it up to date where necessary. As an essayist, Weinberg insists on seeing things as they are, without despair and with good humor. Sure to provoke his readers—postmodern cultural critics, enthusiasts for manned space flight or missile defense, economic conservatives, sociologists of science, anti-Zionists, and religious zealots—this book nonetheless offers the pleasure of a sustained encounter with one of the most interesting scientific minds of our time.
This book is unique in the detailed, self-contained, and comprehensive treatment that it gives to the ideas and formulas that are used and tested in modern cosmological research. It divides into two parts, each of which provides enough material for a one-semester graduate course. The first part deals chiefly with the isotropic and homogeneous average universe; the second part concentrates on the departures from the average universe. Throughout the book the author presents detailed analytic calculations of cosmological phenomena, rather than just report results obtained elsewhere by numerical computation. The book is up to date, and gives detailed accounts of topics such as recombination, microwave background polarization, leptogenesis, gravitational lensing, structure formation, and multifield inflation, that are usually treated superficially if at all in treatises on cosmology. Copious references to current research literature are supplied. Appendices include a briefintroduction to general relativity, and a detailed derivation of the Boltzmann equation for photons and neutrinos used in calculations of cosmological evolution. Also provided is an assortment of problems.

Pochopení přírodních jevů se redukuje na odhalení fundamentálních fyzikálních zákonů a porozumění struktuře hmoty, prostoru a času na mikroskopické úrovni. Přestože tyto zákony nejsou zcela známy, cíl fundamentální vědy je na dosah. Tento pohled na svět je klíčovým motivem sbírky esejů, která zahrnuje vysoce ceněné texty, jako je například Vesmír podle plánu, zařazený do dvou prestižních sbírek nejlepších amerických esejů roku 2000.
Kniha se zaměřuje na filozofické a společenské souvislosti moderní vědy. Autorův sekulární přístup vychází z racionálního pohledu na svět, kde objektivní přírodní zákony nevyčleňují lidské bytosti. V jednotlivých kapitolách autor poutavě a přesvědčivě prezentuje své názory na různá témata, včetně otázek kolem Velkého třesku, stavu fyziky elementárních částic a možné existence „velkého návrháře“ Vesmíru. Kritizuje postmoderní útoky na vědu jako odraz předsudků kritiků a jejich neporozumění vědecké literatuře. Vysvětluje, že touha porozumět přírodě je klíčová pro osvobození lidského ducha a podporuje moderní liberální uspořádání společnosti.
In this two-volume work, Nobel Laureate Steven Weinberg presents a self-contained and comprehensive introduction to quantum field theory, blending exceptional physical insight with clear exposition. Volume I lays the groundwork by logically developing the foundations of quantum field theory, carefully motivating each step and emphasizing its relevance to understanding nature. Starting with a brief historical overview, the text revisits the principles of relativity and quantum mechanics, leading to the natural emergence of quantum field theory. Weinberg modernizes classic calculations of quantum electrodynamics, employing path integrals and dimensional regularization, while his treatment of renormalization reflects evolving perspectives since the introduction of effective field theories. The scope extends beyond quantum electrodynamics to encompass elementary particle and nuclear physics, enriched with original material, examples, and insights from the author’s extensive research experience. Each chapter concludes with problems, making this work an invaluable reference for physicists and mathematicians utilizing quantum field theory. It also serves as an appropriate textbook for graduate students in the field.
An understanding of nature's final laws may be within our grasp - a way of
explaining forces and symmetries and articles that does not require further
explanation. In it he discusses beauty, the weakness of philosophy, the best
ideas in physics and the honour of accepting a world without god.
A Nobel Prize-winning physicist explains what happened at the very beginning of the universe, and how we know, in this popular science classic. Our universe has been growing for nearly 14 billion years. But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life. In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together. Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.
