Základní kurz na většině středověkých univerzit se skládal ze studia sedmi svobodných umění. Nižší úroveň (gramatika, rétorika a dialektika) se nazývala trivium a úroveň vyšší, kvadrivium, zahrnovala studium aritmetiky, geometrie, hudby a astronomie. Kvadrivium lze chápat jako studium čísel ve vztahu k prostoročasu: aritmetika se zabývá čistými čísly, geometrie čísly v prostoru, hudba čísly v čase a astronomie (kosmologie) čísly v časoprostoru. Kniha Kvadrivium vznikla jako syntéza šesti publikací řady Pergamen, která pro českého čtenáře již téměř deset let systematicky mapuje lidské poznání na pomezí vědy a tajemna. Stejně jako u jednotlivých titulů řady jde o atraktivně graficky zpracované ochutnávky velkých témat, které se nebrání mystice ani čisté spekulaci. Jednotlivé knihy byly pro Kvadrivium aktualizovány, doplněny o řadu nových kapitol, tabulek a přehledů a propojeny odkazovým aparátem. Kniha poskytne mnoho potěšení každému, kdo se nebojí přemýšlet o velkých tématech, a uvítá názorného průvodce po jejich říši s doprovodem stovek půvabných ilustrací.

Ve druhém dílu fantasy ságy se Jednomyslně zvolení setkají se zlem v nové podobě, ale je to hlavně Samuel, který mu bude čelit tváří v tvář. Přešel času běh a draci zmizeli. Zdálo by se, že zlo je poraženo a Jednomyslně zvolení bez překážek dostojí svému slibu. S jakou lehkostí by se tomu dalo uvěřit. Jenže pravda je jiná a odhaluje bezduché násilí, které tu po dracích zůstalo a z jehož temné hlubiny se vynoří hrůzovláda netušené síly. Ale prozatím není nic ztraceno a Poutník, Modrooká, Horal, Lovec a Johan jedou vstříc nové naději.

Mastersmith Elof Valantor pursues his love, Kara, to an unknown land where he is faced with the greatest challenge of his life

At last, the costly and bitter war between the two Foundations had come to an end. The scientists of the First Foundation had proved victorious; and now they retum to Hari Seldon's long-established plan to build a new Empire that the Second Foundation is not destroyed after all-and that its still-defiant survivors are preparing their revenge. Now the two exiled citizens of the Foundation-a renegade Councilman and the doddering historian-set out in search of the mythical planet Earth. . .and proof that the Second Foundation still exists. Meanwhile someone-or something-outside of both Foundations sees to be orchestrating events to suit its own ominous purpose. Soon representatives of both the First and Second Foundations will find themselves racing toward a mysterious world called Gaia and a final shocking destiny at the very end of the universe!

Golan Trevize, former Councilman of the First Foundation, has chosen the future, and it is Gaia. A superorganism, Gaia is a holistic planet with a common consciousness so intensely united that every dewdrop, every pebble, every being, can speak for all—and feel for all. It is a realm in which privacy is not only undesirable, it is incomprehensible. But is it the right choice for the destiny of mankind? While Trevize feels it is, that is not enough. He must know. Trevize believes the answer lies at the site of humanity's roots: fabled Earth . . . if it still exists. For no one is sure where the planet of Gaia's first settlers is to be found in the immense wilderness of the Galaxy. Nor can anyone explain why no record of Earth has been preserved, no mention of it made anywhere in Gaia's vast world-memory. It is an enigma Trevize is determined to resolve, and a quest he is determined to undertake, at any cost.[ Original description here: Горстка смельчаков пытается найти прародину человечества - Землю, чтобы получить разгадку тайн истории Галактики. = A handful of brave souls trying to find humanity's ancestral home—the Earth, to get answers to the mysteries of the history of the Galaxy.]

Sparhawk, Pandion-ridder en kampioen van de koningin, keert na een verbanning van tien jaar terug naar Elenië.

Alleen de Bheliom, een legendarisch magisch Amulet, kan haar redden. Elenië wordt geregeerd door een Prins-Regent, een stroman van de ware machthebber, de Primaat Annias, die de leider van de Kerk. Samen met Sephrenia en zijn oude schildknaap, begint Sparhawk aan een wanhopige queeste op zoek naar de Bhelliom om koningin Ehlana te bevrijden.

David Eddings returns to The Elenium, the splendid fantasy series that began with the thrilling novels Diamond Throne and Ruby Knight. Finally the knight Sparhawk had come to possess Bhelliom, legendary jewel of magic that alone could save Queen Ehlana from the deadly poison that had felled her father. Sparhawk and Sephrenia, ageless instructor in Styric magics, made haste to free Ehlana from the crystalline cocoon that had preserved her life while they desperately sought a cure. But Bhellion carried dangers of its own. Once the stone came into his hands, Sparhawk found himself stalked by a dark, lurking menace. Whether the foul Zemoch God Azash was behind this threat, or some other enemy, even Sephrenia could not say—only that the sapphire rose held powers too dangerous for any mortal to bear. Restoring Queen Ehlana would be only the beginning of Sparhawk’s mission. With the aid of four stalwart knights, one from each Militant Order, he must thwart Ehlana’s prisoner, the Primate Annias, in his plot to assume the throne of the Church. For as Archprelate, Annias would serve his secret master, Azash, and deliver up to the dread God the one thing Azash thirsted for—Bhelliom itself!

Everybody has regrets, Daniel H. Pink explains in The Power of Regret. They're a universal and healthy part of being human. And understanding how regret works can help us make smarter decisions, perform better at work and school, and bring greater meaning to our lives. Drawing on research in social psychology, neuroscience, and biology, Pink debunks the myth of the "no regrets" philosophy of life. And using the largest sampling of American attitudes about regret ever conducted as well as his own World Regret Survey-which has collected regrets from more than 15,000 people in 105 countries-he lays out the four core regrets that each of us has. These deep regrets offer compelling insights into how we live and how we can find a better path forward. As he did in his bestsellers Drive, When, and A Whole New Mind, Pink lays out a dynamic new way of thinking about regret and frames his ideas in ways that are clear, accessible, and pragmatic. Packed with true stories of people's regrets as well as practical takeaways for reimagining regret as a positive force, The Power of Regret shows how we can live richer, more engaged lives

Decades ago, Japan won the Second World War. Americans worship their infallible Emperor, and nobody believes that Japan's conduct in the war was anything but exemplary. Nobody, that is, except the George Washingtons -- a group of rebels fighting for freedom. Their latest terrorist tactic is to distribute an illegal video game that asks players to imagine what the world might be like if the United States had won the war instead. Captain Beniko Ishimura's job is to censor video games, and he's tasked with getting to the bottom of this disturbing new development. But Ishimura's hiding something...kind of. He's slowly been discovering that the case of the George Washingtons is more complicated than it seems, and the subversive videogame's origins are even more controversial and dangerous than the censors originally suspected. A spiritual sequel to Philip K. Dick's The Man in the High Castle, United States of Japan carries on the legacy of Dick's famous alternate history, focusing on how Americans and Japanese deal with their guilt and troubled relationship to the past.

Naomi Seberg and Nathan Math, sensational photojournalists of the digital age, are both lovers and rivals. They traverse the world separately, meeting only in airport hotels or online, always in search of spectacular, often sordid stories. The case of Célestine and Aristide Arosteguy, a libertine couple and former philosophy professors, particularly captivates Naomi. Célestine is found mutilated in her Paris apartment, and her missing husband is suspected of having murdered and cannibalized her. Accompanied by Hervé Blomqvist, an eccentric student, Naomi embarks on a quest to find Aristide, leading her to Tokyo. Meanwhile, Nathan is in Budapest photographing Zoltán Molnár, a controversial surgeon wanted by Interpol for organ trafficking. After having an affair with one of Molnár's patients, Nathan contracts a strange illness, the "Roiphe disease," and travels to Toronto to meet the doctor who identified this mysterious syndrome. These parallel narratives intertwine in a plot that blends technology, body, 3D printing, and philosophy, exploring dark themes of death and sex in all its forms. David Cronenberg delves into the psychological and physical darkness of humanity in this debut novel, incorporating his cinematic themes and aesthetics.

Kniha esejí "O Pálení kníh" po prvý raz zhrnula do jedného zväzku štyri texty od Ericha Käastnera, v ktorých autor rozpráva, čo sa v roku 1933 – a aj neskôr stalo, ako sa to stalo a prečo sa to stalo. Erich Käastner je dvojitý korunný svedok hanebného činu – pálenia kníh. V noci 10. mája 1933 musel na námestí opery v Berlíne hľadieť, ako nacisti hádžu do ohňa jeho knihy a v roku 1965 v Düsseldorfe zažil, ako jeho knihy páli Spolok odhodlaných kresťanov.
