People have always been interested in numbers, in particular the natural numbers. Of course, we all have an intuitive notion of what these numbers are. In the late 19th century mathematicians, such as Grassmann, Frege and Dedekind, gave definitions for these familiar objects. Since then the development of axiomatic schemes for arithmetic have played a fundamental role in a logical understanding of mathematics. There has been a need for some time for a monograph on the metamathematics of first-order arithmetic. The aim of the book by Hajek and Pudlak is to cover some of the most important results in the study of a first order theory of the natural numbers, called Peano arithmetic and its fragments (subtheories). The field is quite active, but only a small part of the results has been covered in monographs. This book is divided into three parts. In Part A, the authors develop parts of mathematics and logic in various fragments. Part B is devoted to incompleteness. Part C studies systems that have the induction schema restricted to bounded formulas (Bounded Arithmetic). One highlight of this section is the relation of provability to computational complexity. The study of formal systems for arithmetic is a prerequisite for understanding results such as Gödel's theorems. This book is intended for those who want to learn more about such systems and who want to follow current research in the field. The book contains a bibliography of approximately 1000 items.

This analysis of Neolithic long barrows in Bohemia uncovers new insights into their construction, significance, and role in spiritual traditions. Neolithic long barrows in Bohemia were long neglected by archaeologists due to their destruction by modern intensive agricultural activity. This new analysis, resulting from a three-year interdisciplinary research project, of the phenomenon of Neolithic long barrows in Bohemia and Central Europe presents entirely new findings and data and tackles a number of previously unresolved questions. New discoveries, based primarily on remote sensing and targeted excavations, together with the revision of earlier archaeological records, allow us to define more accurately the construction and chronological development of these monuments, and to advance our knowledge of the southeastern boundary of this phenomenon's spread together with reconstruction of the social and religious significance of these monuments for the agricultural communities of Central Europe. At the sacred places defined by the long barrows, ceremonies and rituals took place over millennia that confirmed the cohesion of the living with the ancestors and their faith in the gods. People, even many generations later, continued to venerate these ancient monuments, not as places of final rest for their direct ancestors but as places dedicated to mythical time, where the living meet the dead and honour the gods. It is not surprising, therefore, that people added the burials of their own ancestors to the embankments of ancient barrows and established their own funerary areas nearby even after several millennia. All long barrows excavated within our project contained only one primary burial: in Bohemia these were not collective graves as found, for example, in the British Isles or Scandinavia. Given the monumentality of barrow construction, it can be presumed that the buried individuals represented a form of social elite, though not necessarily due to their individual social power. It seems that the primary burial played the role of an initiation sacrifice: a ritual of consecration of the ancestor sanctuary, which then no longer served for further burials that may have been taboo. Subsequent activities may have been related to forms of ancestral cult, but the primary burial was not followed by other funerary events. All evidence of later burials is at least 1000 years later than barrow construction. In the region around the Czech mythical Mountain ?íp, burial monuments from various prehistoric periods, including the Late Neolithic, abound. Residential and economic activities on the plains appear later. It can be assumed that this area was perceived as a ritual landscape in earlier prehistory in which long barrows played a significant role in structuring the farming landscape and as significant landmarks. Their monumentality initiated a long-standing tradition creating palimpsests of funerary and sacred sites near Mount ?íp. The places where the long barrows were built played an important role in the lives of prehistoric communities, and their placement and orientation in the landscape was not random, indicating significant symbolic connotations with the surrounding landscape. The rituals and festivities held here allowed people to connect with the spiritual legacy of their ancestors, thus creating a significant spiritual tradition inscribed in the agriculturally colonised landscape.

The Russian anarchist Peter Kropotkin was the world's foremost spokesman of anarchism at the end of the nineteenth and the beginning of the twentieth centuries. The Conquest of Bread is his most detailed description of the ideal society, embodying anarchist communism, and of the social revolution that was to achieve it. Marshall Shatz's introduction to this edition traces Kropotkin's evolution as an anarchist, from his origins in the Russian aristocracy to his disillusionment with the Russian Revolution, and the volume also includes a hitherto untranslated chapter from his classic Memoirs of a Revolutionist, which contains colourful character-sketches of some of his fellow anarchists, as well as an article he wrote summarising the history of anarchism, and some of his views on the Revolution.

History of pi, says the author, though a small part of the history of mathematics, is nevertheless a mirror of the history of man. Petr Beckmann holds up this mirror, giving the background of the times when pi made progress and also when it did not, because science was being stifled by militarism or religious fanaticism. The mathematical level of this book is flexble, and there is plenty for readers of all ages and interests.

Leaving his beloved meadow behind helps Hare discover what makes it such a special place in this captivating new book from acclaimed author-illustrator Petr Horácek. Hare’s meadow is a beautiful place, but he can’t tell whether it’s the best place in the world. His friends all say it is. The rabbits love to run and play together in the fields, the birds love to sing to Hare from high up in the trees, and Bear loves the bees and the honey they share with everyone. But Hare still isn’t certain, so he sets off to explore the world and find out for himself. He discovers green fields, gushing rivers, and starlit deserts. His friends would surely love these places, too, but they’re all back in the meadow without him . . . which leads Hare to realize something important. In a gorgeously written and illustrated story, Petr Horácek masters a tender new tone and delivers a thoughtful meditation on what makes a home.

A moving fable about friendship and belonging from award-winning illustrator Petr Horácek. Far away, near the South Pole, a blue penguin is born. It is not something you see every day. “I feel like a penguin,” says Blue Penguin. “But you’re not like us,” the others tell him. Blue Penguin can’t jump or dive very well, so the others wander off and leave him behind. In his loneliness, Blue Penguin begins to dream, and he starts to sing. Will he ever convince the other penguins that he is one of them? Beautifully illustrated in icy blue hues, Blue Penguin is an affecting ode to self-expression and connection by a picture book creator whom the Washington Post has called “the thinking tot’s Eric Carle.”

V pořadí pátá sbírka Petra Hrušky je plná neklidu, ne však těkavosti. Naopak. Tenhle nepokoj má svou pomalost, váhu a zaťatost, své hrany. Těžkne, tlačí, dře, znaveně se vrývá pod kůži. Život je již za půlí své pouti, podstatná poznání, zásadní chvíle, činy, zvraty i chyby máme za sebou, ale svět a život nepřestávají naléhat. I toto naléhání stárne, hranatí a těžkne; tak známé, a přece někdy sotva pojatelné. Rozumíme si ještě, svému jazyku, jeden druhému či aspoň trochu sami sobě? Anebo jsme, spolu s okolními věcmi, městem a vůbec celým světem, stiženi podivným mutismem? Neschopni ze sebe vypravit kloudné slovo, větu? Hrany světa hrubnou a dřou, jsou otřískané, osahané k nepoznání. Nějak tím vším však musíme projít. V tomhle městě jménem Ostrava si musíme vyrobit své trudné, umanuté palivo k přežití. V této neladné, pracné noci, zatímco slušní lidé zaspávají zkázu, se básníka vytrvale drží jeho nespavost. Někdo tu stráž má dotáhnout do konce.

Objevujte znovu kouzlo a historii železnice ve volném pokračování knihy Zmizelé koleje, zmizelá nádraží, vydané v roce 2019. Vzhledem k obrovskému historickému rozsahu se do první publikace nemohly vejít všechny zaniklé tratě. Díky tomu měli autoři dostatek témat a materiálů ke zpracování, a čtenáři se tak dostává druhé pojednání o tratích, které si někteří ještě možná pamatují, ale pro většinu čtenářské obce bude překvapením, kde všude existovaly veřejné železnice a kde kdysi stávala malebná nádraží. Velkou kapitolu tvoří železnice přeshraniční, které zanikly zejména změnou poměrů po druhé světové válce. Některé z nich byly po několika desetiletích znovu vybudovány a byl na nich opět zahájen provoz. Kromě jiného se dále více dozvíte o tratích a přeložkách, které nebyly popsány v první knize a díky časovému odstupu se podařilo získat další zajímavou historickou dokumentaci. Stejně jako v prvním dílu, i teď se můžete těšit na přehledné mapky a jedinečné fotografie. Z obsahu: Příhraniční a přeshraniční tratě Tratě nesjízdné nebo zrušené na kterých byl obnoven provoz Zrušené tratě neuvedené v prvním dílu Přeložky tratí pokračování Přeložky na koridorech, začátky a současnost Dráhy prodané jiným provozovatelům Dráhy v řízení o zrušení Dráhy nesjízdné

Petr Uličný, legendární John, vypráví o svých hráčských začátcích, o své trenérské kariéře, která byla pěkně spletitá, protože kvůli své „komunikativnosti“ vystřídal několik klubů, a nevyhýbá se ale ani vyprávění o svém soukromí a milované rodině. Autor sleduje kariéru tohoto rodáka z Kroměříže, mapuje jeho úspěchy a neúspěchy, ale zároveň nechá v plné síle působit opravdovost a ohromný zapálení, se kterým Bouřlivák John všechno prožívá. Z každé věty na nás dýchne osobitost a nesmírná autenticita, kterou si dokázal získat sympatie svých přátel a kolegů, ale kterou i mnohé z nich popudil. Mozaiku profesního a osobního života „nepřeslechnutelného“ trenéra doplňují svými postřehy jeho kamarádi a kolegové, například Pavel Vrba nebo Karel Brückner. Jaké byly začátky Petra Uličného? Proč se mu říká John? Co o něm říkají jeho spoluhráči a přátelé a jak ho vidí jeho žena? Kdy si zazpíval s Pavlem Bobkem? V čem vidí naději pro český fotbal? Přečtěte si, co všechno na sebe Bouřlivák John prozradil a proč se neodmyslitelně zapsal do fotbalové historie a do srdcí všech milovníků fotbalu.
