"Stephen Hawking's closest collaborator offers the intellectual superstar's final thoughts on the cosmos-a dramatic revision of the theory that made him the heir to Einstein's legacy. Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led Hawking to study the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse-countless different universes, most far too bizarre to harbor life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked shoulder to shoulder for twenty years on a new quantum theory of the cosmos. As their journey took them deeper into the big bang, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. Once upon a time, perhaps, there was no time. This led them to a revolutionary idea: the laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. On the Origin of Time takes the reader on a quest to understand questions bigger than our universe, peering into the extreme quantum physics of black holes and the big bang and drawing on the latest developments in string theory. As Hawking's final days drew near, the two collaborators developed a final theory proposing their radical new Darwinian perspective on the origins of our universe. Hertog offers a striking new vision that ties together more deeply than ever the nature of the universe's birth with our existence. This new theory profoundly transforms the way we think about our place in the order of the cosmos and may ultimately prove Hawking's biggest legacy"--

"Ich sehe Alligatoren mit Posaunen!" - Muhammad Ali; Kinshasa, 1974Die Zutaten hätten dramatischer nicht sein können: Inszeniert von einem kriminellen Boxpromoter mit Sturmfrisur (Don King) im Reich eines Diktators mit Leopardenfellmütze (Mobutu), trafen am 30. Oktober 1974 in Kinshasa im damaligen Zaire zwei Boxer aufeinander, um sich einen epischen Kampf zu liefern. Der eine war Muhammad Ali, der seine besten Jahre hinter sich hatte, aber entschlossen war, den verlorenen Weltmeistertitel zurückzuerobern. Der andere war George Foreman, der so wortkarg war wie Ali wortgewaltig und als klarer Favorit gehandelt wurde. Millionen Fernsehzuschauer auf der ganzen Welt verfolgten diese spektakuläre Titanenschlacht mit überraschendem Ausgang, die als Rumble in the Jungle in die Geschichte einging.In Kinshasa mit dabei war auch das "Enfant terrible" der amerikanischen Literaturszene, der Starautor und Pulitzer-Preisträger Norman Mailer, der seine Eindrücke und Beobachtungen ein Jahr später unter dem Titel The Fight veröffentlichte, eine literarische Reportage von rund 250 Seiten.In unserer Hommage an das legendärste Boxereignis aller Zeiten erscheint Mailers Text in einer gekürzten Fassung, eingeleitet von einem Essay des Mailer-Experten J. Michael Lennon und erstmals bebildert mit Farb- und Schwarz-Weiß-Fotografien jener beiden Männer, die wie keine anderen Ali sowohl im Ring als auch im Privatleben im Bild festhielten: Howard L. Bingham und Neil Leifer.

In his new book, Stephen Levine, author of the perennial best-seller Who Dies?, teaches us how to live each moment, each hour, each day mindfully--as if it were all that was left. On his deathbed, Socrates exhorted his followers to practice dying as the highest form of wisdom. Levine decided to live this way himself for a whole year, and now he shares with us how such immediacy radically changes our view of the world and forces us to examine our priorities. Most of us go to extraordinary lengths to ignore, laugh off, or deny the fact that we are going to die, but preparing for death is one of the most rational and rewarding acts of a lifetime. It is an exercise that gives us the opportunity to deal with unfinished business and enter into a new and vibrant relationship with life. Levine provides us with a year-long program of intensely practical strategies and powerful guided meditations to help with this work, so that whenever the ultimate moment does arrive for each of us, we will not feel that it has come too soon.

Gnostics have always sought to "know" rather than to accept dogma and doctrine, often to their peril. This inquiry into Gnosticism examines the character, history, and beliefs of a brave and vigorous spiritual quest that originated in the ancient Near East and continues into the present day.Lawrence Durrell writes, "This is a strange and original essay, more a work of literature than of scholarship, though its documentation is impeccable. It is as convincing a reconstruction of the way the Gnostics lived and thought as D.H. Lawrence's intuitive recreation of the vanished Etruscans."

When Robert Pirsig's Zen and the Art of Motorcycle Maintenance was first published in 1974, it caused a literary sensation. An entire generation was profoundly affected by the story of the narrator, his son, Chris, and their month-long motorcycle odyssey from Minnesota to California. A combination of philosophical speculation and psychological tension, the book is a complex story of relationships, values, madness, and, eventually, enlightenment.Ron Di Santo and Tom Steele have spent years investigating the background and underlying symbolism of Pirsig's work. Together, and with the approval of Robert Pirsig, they have written a fascinating reference/companion to the original.Guidebook to Zen and the Art of Motorcycle Maintenance serves as a metaphorical backpack of supplies for the reader's journey through the original work. With the background material, insights, and perspectives the authors provide, Guidebook to Zen and the Art of Motorcycle Maintenance is destined to become required reading for new fans of the book as well as those who have returned to it over the years.

Brilliant, funny, charming, imperious, Diana Vreeland?the fashion editor of Harper's Bazaar and editor-in-chief of Vogue?was a woman whose passion and genius for style helped define the world of high fashion for fifty years. Among her eclectic circle of friends were some of the most renowned and famous figures of the twentieth century?artists and princes, movie stars and international legends, including Chanel, the Duke and Duchess of Windsor, Isak Dinesen, Clark Gable, and Swifty Lazar.Moving from English palaces to the nightclubs of 1930s Paris, the wilds of Wyoming to the exclusive venues of New York high society, D.V. takes readers into this iconic woman's dazzling life, evoking the luxury and brio of an era that encompassed Josephine Baker, England's Queen Mary, Buffalo Bill, and Diaghilev.Vibrant with the vivid, irresistible voice that elevated every tête-à-tête and dinner party, D.V. brings this renowned and uninhibited raconteur alive, whether recalling herself as a young girl, her search for the perfect red, her piquant observations about her world, or her abhorrence for nostalgia. Like her legacy, Vreeland's story, told in her own words, is a classic to be celebrated by both loyal admirers and a new generation of culture mavens and style savants.

Ny udgave med et længere nyskrevet efterord af Tor Nørretranders.Om fysikeren Niels Bohrs (1885-1962) rolle i atomfysikkens begyndelse og om udviklingen af det kvante-mekaniske verdensbillede, de erkendelsesteoretiske og begrebslige vanskeligheder heri samt om Niels Bohrs indsats i atomvåbenspørgsmålet.

Stephen Hawking var et enestående menneske. På én gang en ikonisk skikkelse i vores populærkultur, skelsættende forfatter og formidler af videnskabeligt stof til den almene læser, en dreven spøgefugl – og sidst, men ikke mindst en helt afgørende forsker, der bidrog med grundlæggende indsigter til vores forståelse af, hvordan den verden og det univers, som har skabt os, er dannet og fungerer.Fysikeren og forfatteren Leonard Mlodinow mødte første gang Stephen Hawking, da de skrev deres første bog sammen. Leonard og Stephen blev venner – og Mlodinow har været personligt og professionelt tæt på både Hawking, menneskene omkring ham og hans videnskabelige resultater. I ‘Stephen Hawking’ beskriver Leonard Mlodinow i seks kapitler, hvorfor Stephen Hawking var så stor og vigtig en videnskabsmand – og forklarer det, så vi alle kan være med. Det bliver en rejse, hvor vi bevæger os med Hawking ind i det mærkværdige og de vilde sorte huller, ser ham bevise, at tiden måske slet ikke findes og følger ham i hans arbejde med teorien om, at der findes mange verdener og parallelle universer. Og hvor vi samtidig møder ham som menneske. Medrivende, bevægende og storslået. Et indblik i et rigt sind og en stor ånds univers.

Eller med andre ord… - som en selvhelbredende kraft snarere end på det materielle niveau. I kraft af, at sygdomme er mere almindeligt diagnosticeret som ubalance af legemsenergi, er energimedicin blevet det mest efterspurgte alternativ til den traditionelle vestlige medicin. I den komplette bog af energimedicin giver Dr. Helen Dziemidko os et omfattende kig på energilægemidler. Hun kombinerer det lægefaglige og videnskabelige synspunkt med en udtømmende viden om energihelbredende metoder - fra akupunktur og yoga til Bach Flower terapi og homøopati.Med klare, tilgængelige forklaringer leder hun læseren gennem mere end 50 komplementære terapier som adresserer de 20 mest almindelige kroniske lidelser.Bogen er en international bestseller - nu udgivet på dansk. Den giver en nem guide til at hjælpe læserne med at identificere deres lidelser og de mulige årsager, og derefter vise, hvilke energimediciner der giver den bedste vej mod helbredelse.

Peter Høeg er tilbage med en charmerende og begavet spændingsroman om fysikeren Susan Svendsen og hendes højst usædvanlige talent.Susan er 43 år, lektor i eksperimentalfysik, veltrimmet vinterbader, gift med Laban og mor til teenage-tvillingerne Harald og Thit. Hun finder ro i det periodiske system og ser naturlovene som en garanti for orden og regelmæssighed. Men Susan er selv et særtilfælde: Hun har en helt forbløffende evne til at fremkalde oprigtighed. Mennesker betror sig ganske spontant til hende.Dette talent har hun misbrugt, og nu truer en lang fængselstraf. En tidligere embedsmand tilbyder hende en sidste udvej, men kun på én betingelse: Hun skal opspore det sidste overlevende medlem i den såkaldte Fremtidskommision fra 1970’erne og afsløre, hvad der stod i referatet af deres sidste møde. Det er hemmeligheder med vidtrækkende konsekvenser, og nogen kommer Susan brutalt i forkøbet.Effekten af Susan er en eventyrlig og hæsblæsende roman om oprigtighed – i familien, i videnskaben og i samfundslivet.Pressen skriver: »… først og sidst er Peter Høeg sin egen og i topform. Susan Svendsen […] er skabt af sprog, som funkler. Netop den sproglige virtuositet udgør halvdelen af nydelsen i denne toptunende og ferme femi- og klimathriller.«***** - Jes Stein Pedersen, Politiken »Hvis De kun skal læse én apokalyptisk videnskabs-thriller i år, så lad det blive ”Effekten af Susan.«***** - David Jacobsen Turner, Jyllands-Posten »En glimrende tur i Høeget … Han er ikke for fin til at bruge lavkomik eller filmiske thrillergreb, når han fortæller historien om Susan - og det virker.«***** - Line Rasmussen, Børsen »Peter Høeg er aktuel med romanen "Effekten af Susan", hvis hovedperson bringer tankerne hen på en vis frøken Smilla. Det er ikke tit, Høeg barsler med en ny roman, men denne har været værd at vente på.«***** - Kultunaut»Hvorfor nøjes med litterære gråspurve, der pikker lidt i borgernes tagrender, når der findes en frit flyvende høg, for hvem ingen regler blokerer for en regulær lemlæstelse af byttet! Nej, vel, så her får man muligheden. Peter Høeg er på banen igen, mere oplagt end længe, og med en roman, der både er thriller, samfundsrevser og eksistentielt provokerende; og så er den vidunderligt morsom.«****** - Preben Rasmussen, Dagbladenes Bureau »Peter Høeg er tilbage med en thriller om kvantefysik, og hvordan elitens svigt af masserne allerede er virkelighed … Romanen er et centrifugalaccelereret cirkelspark i borgerskabets moderne pudderparyk. Og det kan de så hygge sig med oppe på Business Class. I mellemtiden kan vi andre læsebogens dybere litterære kvaliteter frem.«– Kristian Ditlev Jensen, Weekendavisen»Peter Høeg er tilbage på toppen … Man er simpelthen skamløst godt underholdt fra første til sidste side.«- Nils Gunder Hansen, Kristeligt Dagblad »Høeg er en gudbenådet fortæller, der her igen har skrevet en bog, man sluger råt fra start til slut. «***** - Alt for damerne

En forårsaften i København 1925. En ung tysk videnskabsmand har en hel nat diskuteret atomfysik med sin mentor, professoren på Institut for Teoretisk Fysik. I Fælledparken ser den unge fysiker en mand, der bevæger sig ind og ud af gadelygternes lyskegler. En tilfældighed, der for altid vil ændre vores verdensbillede.Christian Haller – en af Schweiz’ mest velansete forfattere og selv naturvidenskabsmand – har skrevet en roman om sorg og ensomhed, om grænserne for vor viden og om de mest grundlæggende spørgsmål: Hvor pålidelig er vores opfattelse af verden? Hvor er genstandene, når vi ikke kan se dem? Hvordan tale om det usigelige?

Denne anvisning har til formål at danne et detaljeret overblik over de varmeisoleringsmaterialer, der på nuværende tidspunkt er på det danske marked, dels ved at beskrive væsentlige egenskaber, og dels hvordan materialerne kan anvendes i udvalgte bygningsdele. Først behandler anvisningen emnerne dokumentation og egenskaber for varmeisoleringsmaterialer som helhed for at lette sammenligningen på tværs af materialetyper. Det omfatter bl.a. deklarering og CE-mærkning, varmeledningsevne, brandtekniske egenskaber, fugttekniske egenskaber og bæreevne. Andre forhold af betydning for anvendelse af materialer til varmeisolering af bygninger, som livscyklusvurdering, tilsætningsstoffer og arbejdsmiljø, behandles også. Derefter beskrives 28 forskellige varmeisoleringsmaterialer hver for sig med fokus på egenskaber og typisk anvendelse. Anvisningen beskriver funktionskrav til ydervægge, terrændæk og tag med særligt fokus på, hvad man skal være opmærksom på ved anvendelse af materialer til varmeisolering, og eksempler på udformninger, der lever op til disse krav. Den viser også eksempler på forskellige konstruktioners klimapåvirkning for at illustrere, hvilken betydning valget af materialer har for en given bygningsdel ved en livscyklusvurdering. Afslutningsvis giver anvisningen eksempler på efterisolering af muret etagebyggeri. Anvisningen er rettet mod projekterende og udførende i byggebranchen, professionelle bygherrer, bygningsmyndigheder samt producenter og leverandører af isoleringsmaterialer. Anvisningen kan også anvendes i undervisningsøjemed.

The way to the heart is through the stomach - and perhaps this also applies to intercultural understanding. Most of Julia Goodman's ancestors were Eastern European Jews who emigrated to the USA at the beginning of the 20th century. Gabriele Edlbauer on the other hand grew up on an organic farm in the predominantly Catholic Mühlviertel region of Upper Austria. While gnawing on chicken bones together, the two women came to chat about the significance of certain foods in relation to their own identity. After all, chickens feature in Julia's most important life memories. Since her family always had a chicken recipe at hand for every holiday, including the weekly Shabbat, it was no surprise that the bird eventually became Julia's favorite dish. Gabi's most prominent childhood memories of chickens are less culinary: the hens on the family farm mainly served an economic purpose.Through sharing their stories, they both soon realized that their connections with chicken and their respective artistic approaches were entangled in strange ways. In the process of cooking together, they developed a fascination with the idea of how certain dishes can convey or trigger very specific feelings. The result is a humorous, artistic attempt to expose complex feelings and hard truths in chicken recipes. This book is filled with emotional recipes - accompanied by creative serving suggestions - and invites you to express yourself through chicken.
