New Releases by Vaclav Smil

From the internationally bestselling author, a revealing look at the surprising numbers that uncover the hidden forces shaping our world ''There is no author whose books I look forward to more'' Bill Gates ‘There is perhaps no other academic who paints pictures with numbers like Smil’ Guardian What do marriage, milk and the black market tell us about the state of humanity? Most people would say, not much at all. But the numbers reveal startling truths about who we are, how we live and where we’re headed. For centuries we’ve told ourselves stories about how the world works – yet the data often point to a very different reality. In Numbers Tell Stories, Vaclav Smil shows how statistics challenge conventional thinking and illuminate the hidden forces shaping our lives. Take marriage. Weren’t people in the past married off as children? In fact, in eighteenth-century France, the median age was 29 for men and 27 for women – not that different to today. Or longevity. Should we look to Japan to unlock the secrets of a long, healthy life? Perhaps – but only one in five Japanese men and women retains full independence in old age. Even the world’s healthiest nation still has far to go. And waste. It sounds absurd, but discarded electronics contain more gold per ton than gold ore itself – our rubbish is richer than our mines. Climate change is another challenge we know is huge – but the real shock is the scale of the economic effort required to act in time. Cutting greenhouse gas emissions on the recommended timescale would demand 15 to 20 per cent of annual GDP in wealthy countries – roughly equivalent to the resources mobilised by the Allies to win the Second World War. Numbers on that scale are not abstract: they would transform daily life. Behind every familiar story, Smil uncovers the statistics that can reframe the past, jolt our view of the present, and change how we think about the future.

A data-driven, scientific account of our need for speed—exploring a wide range of topics including evolution, transportation, and technology In a world obsessed with efficiency, perhaps nothing is valued as highly as being fast. Some of our greatest achievements include building planes that break the sound barrier and creating computers that process data at the touch of a button. With signature clarity, Smil offers accessible explanations of every major speed category, from wind erosion to hunting cheetahs, from Boeing 747s to America’s war time industrial mobilization to the speed of global energy decarbonization. But as Smil argues in this paradigm-shifting book, speed isn’t just a metric to optimize. In Speed, Smil expands on our traditional, human-centric understanding of speed to explore phenomena of space and time, evolution, and human achievement. What was the speed of planet formation? Of the development of different life forms? What happened in the collision of humans and the limits of natural speed, and what has emerged from our incessant desire to push those boundaries? Lauded for his“compelling, fascinating, realistic” (Steven Pinker) portraits of the modern world, Smil knows that we can’t, won’t, and shouldn’t abandon our collective need for speed. But as good devotees of speed’s eminence, we must understand it, its value, and its cost. Rich in historical and contemporary data, the latest work by Smil is a comprehensive, interdisciplinary guidebook for science readers living in the fast lane.

" Un livre lucide, passionnant et rigoureusement chiffré sur le poids environnemental gigantesque de notre nourriture. " Jean-Baptiste Fressoz Jamais nous n''avons dû nourrir autant d''êtres humains qu''aujourd''hui. Et pourtant, nous comprenons encore mal d''où vient réellement notre nourriture, comment nos besoins alimentaires façonnent nos sociétés, et pourquoi cela bouleverse si profondément notre environnement. Dans cet essai lucide et nécessaire, Vaclav Smil démonte les idées reçues et affronte les grandes questions de notre époque : pourquoi certains des plus grands producteurs mondiaux comptent-ils aussi parmi les pays les plus sous-alimentés ? Pourquoi gaspillons-nous tant ? Pourrions-nous tous devenir végans –; et le devrions-nous ? S''appuyant sur des décennies de recherche et de données concrètes, Smil explore l''histoire et l''avenir de la production alimentaire mondiale pour comprendre comment nourrir une population croissante sans compromettre les ressources de la planète. -- " Un auteur clé sur la place de l''énergie dans le monde. " Jean-Marc Jancovici " Vaclav Smil est mon auteur préféré. " Bill Gates " Une pensée claire, documentée, qui balaie les illusions pour mieux éclairer l''avenir. " Nature " Aucun autre universitaire ne manie les chiffres comme Smil pour en faire des images parlantes. " The Guardian " Indispensable pour qui veut comprendre la sécurité alimentaire mondiale. " Financial Times " Le plus grand expert mondial dans le domaine de l''énergie. " Science

La historia de los inventos e innovaciones que han moldeado nuestra civilización, desde las herramientas de piedra hasta la IA. Vaclav Smil, uno de los pensadores más influyentes de nuestro tiempo, ofrece en este libro una narración rigurosa y sorprendentemente amena de la invención humana. Con su estilo característico, Smil explora la sutil diferencia entre invención e innovación, critica el mito del progreso tecnológico acelerado y demuestra que muchas de nuestras ideas sobre el futuro están infladas por un optimismo infundado. Desde el zepelín hasta la fisión nuclear o el avión supersónico, pasando por inventos que terminaron generando graves daños —como la gasolina con plomo o el pesticida DDT—, este recorrido revela no solo los grandes logros que han transformado la economía y la sociedad, sino también sus límites, sus errores y sus consecuencias imprevistas. Además, Smil plantea una lista de invenciones que realmente necesitamos para enfrentar los grandes desafíos del siglo xxi, como la automatización, la IA y el cambio climático. Con un enfoque pragmático y ejemplos cautivadores, Invención e innovación ofrece un relato aleccionador de la locura que con frecuencia acompaña a la creatividad humana y muestra cómo podemos —y debemos— ajustar nuestras expectativas a la realidad. «El mayor experto en el ámbito de la energía». SCIENCE «Vaclav Smil es mi autor favorito. Espero sus libros con la misma impaciencia que algunos esperan el próximo episodio de Star Wars». Bill Gates, fundador de Microsoft

Essen ist eine der wichtigsten Tätigkeiten des Menschen. Mehrmals am Tag nehmen wir Nahrung zu uns. Wie beeinflusst und das, was wir essen, wie wird es produziert und warum landen gerade die wenigen Tiere und Pflanzen auf unseren Tellern, die für den Großteil der weltweiten Kalorienaufnahme herangezogen werden? Warum endet etwa ein Drittel der weltweiten Nahrungsproduktion im Müll? Könnte sich der ganze Planet vergan ernähren und sollte er das? In seinem neuen Buch räumt der renommierte Wissenschaftler und globale Bestsellerautor Vaclav Smil mit vielen Mythen auf und liefert die grundlegenden Fakten und Zahlen dazu, wie wir das herstellen, was uns jeden Tag am Leben hält. Ein ebenso faszinierender wie überraschender Crashkurs zu Geschichte und Gegenwart unsere Ernährung. Noch nie mussten wir so viele Menschen ernähren wie heute. Und doch verstehen immer weniger von uns, woher unsere Lebensmittel wirklich kommen, wie unsere Ernährungsgewohnheiten uns prägen und warum dies unseren Planeten auf drastische Weise beeinflusst. Infolgedessen nehmen wir das, was unser Leben erst möglich macht, oftmals als selbstverständlich hin, nämlich Lebensmittel. Und ihre wirtschaftliche Bedeutung wird auf groteske Weise unterschätzt, so dass Smartphones in Statistiken als ökonomisch viel bedeutsamer erscheinen als Lebensmittel. In seinem neuen Buch verfolgt Vaclav Smil die Entwicklung unserer Nahrungsbeschaffung seit den Anfängen unserer Spezies und untersucht die brennenden Fragen, mit denen die Welt heute konfrontiert ist: Warum verschwenden wir so viele Lebensmittel? Wie können wir die Weltbevölkerung ernähren, ohne den Planeten zu zerstören? Was wirkt und was ist bloß weltfremdes Wunschdenken? Warum züchten wir einige Tiere und andere nicht, und warum stammen die meisten Kalorien auf der Welt aus nur wenigen Nahrungsmitteln? Was kann sich ändern, was muss sich ändern, gerade auch angesichts des Klimawandels?

"Vaclav Smil is my favorite author."—Bill Gates An indispensable analysis of how the world really produces and consumes its food—and a scientist's exploration of how we can successfully feed a growing population without killing the planet We have never had to feed as many people as we do today. And yet, we misunderstand the essentials of where our food really comes from, how our dietary requirements shape us, and why this impacts our planet in drastic ways. As a result, in our economic, political, and everyday choices, we take for granted and fail to prioritize the thing that makes all our lives possible: food. In this ambitious, myth-busting book, Smil investigates many of the burning questions facing the world today: why are some of the world’s biggest food producers also the countries with the most undernourished populations? Why do we waste so much food and how can we solve that? Could the whole planet go vegan and be healthy? Should it? He explores the global history of food production to understand why we farm some animals and not others, why most of the world’s calories come from just a few foodstuffs, and how this might change in the future. How to Feed the World is the data-based, rigorously researched guide that offers solutions to our broken global food system.

Creating and Transforming the Twentieth Century combines two of Vaclav Smil''s seminal works in a revised and expanded edition. Creating the Twentieth Century explores the period between 1867 and 1914, a time of unparalleled innovation that laid the groundwork for modern civilization. It investigates the birth of an expansive society driven by the synergy of fuels, science, and technical innovation. Key inventions from this era include dynamite, the telephone, photographic film, and the first light bulbs in the 1870s, followed by electricity-generating plants, electric motors, steam turbines, and cars in the 1880s. The period of extraordinary discovery continues into the early 20th century with the advent of airplanes, tractors, radio signals, and plastics. Smil systematically examines four fundamental classes of innovations: the formation and standardization of electric systems, the rapid adoption of internal combustion engines, the surge in chemical syntheses and material substitutions, and the dawn of the information age. This interdisciplinary account highlights the epochal consequences of these advancements, leading to high-energy societies engaged in mass production aimed at improving living standards. Transforming the Twentieth Century investigates how these technical advances shaped the decades that followed. It examines how the 20th century differed from the preceding 100 years due to unprecedented combinations of technical progress. Smil discusses the remarkable pace and ambition of 20th-century advancements, which elevated industrial production to new heights and tackled previously insurmountable challenges. He addresses the themes of electricity, engines, materials, and information techniques, and critically examines the contradictory consequences of technological progress--including liberating simplicity versus overwhelming complexity, unprecedented affluence versus economic disparities, and increased security versus new fears. This new edition contains numerous updates to the original books and features a new preface and a final chapter examining key themes in light of major 21st-century events and publications. Now in a single volume, these classic texts remain central to Smil''s acclaimed oeuvre, and their lessons are perennially fascinating.

El mayor experto mundial en el campo de la energía explica por qué no alcanzaremos el objetivo global de cero emisiones en 2050. A pesar de los acuerdos internacionales, la regulación, la inversión pública y privada, el progreso técnico y los cambios de comportamiento, el consumo mundial de combustibles fósiles aumentó un 55 % entre 1997 y 2023. En el mismo periodo, la proporción de combustibles fósiles en el consumo energético global ha pasado del 86 % al 82 %. La cruda realidad es que la transición en curso será muy larga y complicada. Opera a una escala sin precedentes, exige tecnología que aún no ha sido inventada y cantidades ingentes de recursos naturales y plantea imponentes desafíos ambientales, sociales, económicos y geopolíticos. Debemos escoger: invertir un 20 % del PIB mundial en la transición; decrecer voluntariamente (o colapsar involuntariamente); o renunciar al objetivo climático de 1,5 oC y fiar así el mundo al destino, devolviéndole a los dioses lo que la modernidad quiso quitarles. He aquí el trilema en torno al cual gira este breve y fascinante ensayo, escrito por uno de los científicos e intelectuales más originales e influyentes de nuestro tiempo. «Smil es el mejor antídoto que existe contra la estupidez». David Keith, Universidad de Harvard «Una guía imprescindible para comprender el mundo». Jean-Baptiste Fressoz «El mayor experto mundial en cuestión de energía». Science «Cualquier libro de Vaclav Smil es soplo de aire fresco y una joya en la librería». David G. Victor, profesor de Política y Estrategia Global en la Universidad de California «Smil es una de las mentes más lúcidas que conozco y este ensayo es impresionante». Adrián Godás, fundador de Godás Research «Vaclav Smil es mi autor favorito». Bill Gates

Jeszcze nigdy w naszej historii nie dysponowaliśmy tak wieloma informacjami na wyciągnięcie ręki, a mimo to większość z nas nie wie, jak naprawdę działa świat. Dzięki tej książce poznacie i zrozumiecie siedem najbardziej fundamentalnych aspektów, od których zależy nasze przetrwanie i dobrobyt. Począwszy od produkcji energii i żywności, poprzez surowce i globalizację, aż po wszelkie zagrożenia, nasz wpływ na środowisko naturalne i jego przyszłość – książka „Jak naprawdę działa świat” to bardzo potrzebna konfrontacja mitów z rzeczywistością. Bo żeby skutecznie rozwiązywać problemy, musimy najpierw poznać i zrozumieć fakty. Smil nie jest ani optymistą, ani pesymistą. Jest naukowcem. Opierając się na najnowszych badaniach naukowych i stawiając czoła źródłom dezinformacji – od Yuvala Noah Harariego po Noama Chomsky’ego – odpowiada na najdonioślejsze pytanie naszego stulecia: czy jesteśmy nieodwołalnie skazani na zagładę, czy może nasza przyszłość jest jednak bardziej optymistyczna? Kolejne arcydzieło jednego z moich ulubionych autorów. Jeśli chcesz dowiedzieć się, jak liczby opisują fundamentalne siły kształtujące życie człowieka, powinieneś przeczytać tę książkę. To prawdziwytour de force! – Bill Gates Ta książka w stu procentach spełnia obietnicę zawartą w swoim tytule – to chyba najlepsza możliwa rekomendacja – Simon Ings, „New Scientist” Jeśli jesteś zatroskany o naszą przyszłość i rozsierdzony tym, że nie robimy wystarczająco dużo, by o nią zadbać, przeczytaj, proszę, tę książkę – Paul Collier, autor książki „The Future of Capitalism” Bardzo pouczająca książka, otwierająca oczy na wiele zagadnień. – Ha-Joon Chang, autor książki „23 rzeczy, których nie mówią ci o kapitalizmie” Vaclav Smil to wybitny naukowiec i nauczyciel akademicki, emerytowany profesor kanadyjskiego Uniwersytetu Manitoby. Jest autorem ponad czterdziestu książek, poświęconych między innymi energetyce, innowacjom technologicznym, zmianom środowiskowym i populacyjnym, zagadnieniom żywienia i produkcji żywności, problematyce oceny zagrożeń oraz polityce publicznej.

In ''Invenzione e innovazione'', forse il libro più facile da approcciare, il prolifico autore – tra i più amati da Bill Gates – Vaclav Smil propone un viaggio nella storia dell’invenzione umana acuto e ben documentato. Insofferente al clamore che spesso accompagna le innovazioni, in questo libro Smil offre un lucido correttivo alle promesse eccessive create da qualsivoglia scoperta, dalle nuove cure per le malattie all''intelligenza artificiale. L’autore ci ricorda che, anche una volta conclusa la parabola invenzione-sviluppo-applicazione, non è detto che si riesca ad arrivare a qualcosa di concreto. O, peggio ancora, che anche dopo il successo di un''invenzione, il suo futuro potrebbe essere contrassegnato da prestazioni insoddisfacenti, delusioni, ritiro dal mercato o danni collaterali. Attingendo alle sue vaste conoscenze in campo storico e scientifico, Smil spiega la differenza tra invenzione e innovazione, per poi esaminare non solo le invenzioni che non si sono imposte come avrebbero dovuto (per esempio, il dirigibile, la fissione nucleare e il volo supersonico), ma anche quelle che si sono rivelate disastrose (la benzina al piombo, il DDT e i clorofluorocarburi). Per concludere, l’autore offre una sua lista di desiderata, un elenco delle invenzioni di cui più abbiamo bisogno per far fronte alle sfide sconvolgenti del ventunesimo secolo. Ricco di esempi affascinanti analizzati con un approccio pragmatico, questo libro presenta un quadro che fa riflettere sulla follia che spesso va insieme con l’ingegnosità umana, e su come sia possibile, e doveroso, allineare le nostre aspettative alla realtà.

From the New York Times bestselling author of How the World Really Works, a wide-ranging look at the most fundamental governing principle of our world: size, whose laws, limits, and peculiarities offer the key to understanding health, wealth, and even happiness “No one writes about the great issues of our time with more rigor or erudition than Vaclav Smil.” — Elizabeth Kolbert To answer the most important questions of our age, we must understand size. Neither bacteria nor empires are immune to its laws. Measuring it is challenging, especially where complex systems like economies are concerned, yet mastering it offers rich rewards: the rise of the West, for example, was a direct result of ever more accurate and standardized measurements. Using the interdisciplinary approach that has won him a wide readership, Smil draws upon history, earth science, psychology, art, and more to offer fresh insight into some of our biggest challenges, including income inequality, the spread of infectious disease, and the uneven impacts of climate change. Size explains the regularities—and peculiarities—of the key processes shaping life (from microbes to whales), the Earth (from asteroids to volcanic eruptions), technical advances (from architecture to transportation), and societies and economies (from cities to wages). This book about the big and the small, and the relationship between them, answers the big and small questions of human existence: What makes a human society too big? What about a human being? Which alternative energy sources have the best chance of scaling and reducing our dependence on fossil fuels? Why do tall people make more money? What makes a face beautiful? How about a cathedral? How can changing the size of your plates help you lose weight? The latest masterwork of “an ambitious and astonishing polymath who swings for fences” (Wired) Size is a mind-bending journey that turns the modern world on its head.

Der tschechisch-kanadische Wissenschaftler Vaclav Smil ist einer der weltweit führenden Experten für Energiefragen. In diesem Buch unterzieht er die Hoffnung auf eine schnelle Umstellung auf erneuerbare Energien einem Realitätscheck und konfrontiert die politiischen Ziele mit der wissenschaftlichen Realität. Dabei erinnert er daran, auf welchen materiellen Grundlagen unser modernes Leben beruht und wie abhängig wir bei ihrer Produktion bis auf Weiteres von fossilen Brennstoffen bleiben werden. Denn nicht Datenflüsse sind der harte Kern unserer Zivilisation, sondern so unaufregende Dinge wie Stahl, Zement, Ammoniak und Plastik. Wer die Welt verändern will, sollte erst verstehen, wie sie wirklich funktioniert. Die Menschheit hat so viel Wissen angehäuft wie noch nie in ihrer Geschichte. Doch für den Einzelnen werden immer mehr Geräte und Produkte unseres alltäglichen Lebens zu einer Art Blackbox. Wir können damit umgehen, aber verstehen nicht mehr, wie sie wirklichfunktionieren. Immer mehr Menschen haben zudem nur noch oberflächliche Vorstellungen davon, wie wir die Nahrungsmittel, Rohstoffe und Güter herstellen, auf denen unsere Gesellschaft materiell beruht. Dies führt zu Fehleinschätzungen, etwa der, wir könnten unsere Zivilisation in kurzer Zeit von fossilen Brennstoffen auf erneuerbare Energien umstellen. Denn es geht nicht nur um eine nachhaltige Stromproduktion, sondern etwa auch um alternative Verfahren bei der Herstellung von Zement, Stahl, Plastik und Dünger. Technische Innovationen allein reichen nicht, sie müssen auch kommerziell funktionieren und weltweit implementiert werden – in hunderttausenden Fabriken und Produktionsstätten. Wer sich über die Zukunft unseres Planeten Gedanken macht, der sollte die Fakten kennen, die Vaclav Smil in diesem Buch liefert.

Lidstvo ještě nikdy ve své historii nemělo tolik informací, přesto si jen málokdo uvědomuje, jak svět ve skutečnosti funguje. Oceňovaný vědec českého původu Vaclav Smil popisuje a objasňuje složité procesy s neuvěřitelnou lehkostí. Zabývá se sedmi základními principy moderní společnosti, počínaje energiemi přes globalizaci až po výzvy čekající v budoucnosti. Abychom mohli začít řešit problémy, musíme nejdříve pochopit základní fakta. S touto fascinující publikací to bude mnohem snazší.

Czy podróżowanie samolotem jest bezpieczne? Ile ważą wszystkie krowy na świecie? Co sprawia, że ludzie czują się szczęśliwi? „Liczby nie kłamią” to książka o mieszkańcach Ziemi, o pożywieniu i paliwach, które dostarczają im energii, o transporcie i wynalazkach współczesnego świata, a także o tym, jak to wszystko wpływa na naszą planetę. Profesor Vaclav Smil zabiera czytelników na pasjonującą wyprawę, której celem jest odkrywanie faktów. Podsuwając nam zaskakujące dane statystyczne i prezentując pouczające infografiki, zachęca do otrząśnięcia się z intelektualnego lenistwa. Z tej pełnej fascynujących informacji i frapujących przykładów książki dowiemy się między innymi, ilu ludzi potrzebnych było do zbudowania piramidy Cheopsa, dlaczego szczepionki nie tylko ratują życie, ale są także opłacalną inwestycją, i czemu samochody elektryczne nie są (jeszcze) tak dobrym rozwiązaniem, jak nam się wydaje. Smil błyskotliwie łączy wiedzę naukową i historyczną ze zdrowym rozsądkiem, poruszając niezwykle szerokie spektrum zagadnień, które przedstawia w formie krótkich, ale treściwych rozdziałów. „Liczby nie kłamią” to pasjonująca lektura, która prowokuje do stawiania pytań w sprawach zbyt często traktowanych przez nas jako pewnik. Smil udowadnia, że fakty mają znaczenie. Liczby nie kłamią. Jaką prawdę nam zatem przekazują?

INSTANT NEW YORK TIMES BESTSELLER “A new masterpiece from one of my favorite authors… [How The World Really Works] is a compelling and highly readable book that leaves readers with the fundamental grounding needed to help solve the world’s toughest challenges.”—Bill Gates “Provocative but perceptive . . . You can agree or disagree with Smil—accept or doubt his ‘just the facts’ posture—but you probably shouldn’t ignore him.”—The Washington Post An essential analysis of the modern science and technology that makes our twenty-first century lives possible—a scientist's investigation into what science really does, and does not, accomplish. We have never had so much information at our fingertips and yet most of us don’t know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its future, How the World Really Works offers a much-needed reality check—because before we can tackle problems effectively, we must understand the facts. In this ambitious and thought-provoking book we see, for example, that globalization isn’t inevitable—the foolishness of allowing 70 per cent of the world’s rubber gloves to be made in just one factory became glaringly obvious in 2020—and that our societies have been steadily increasing their dependence on fossil fuels, such that any promises of decarbonization by 2050 are a fairy tale. For example, each greenhouse-grown supermarket-bought tomato has the equivalent of five tablespoons of diesel embedded in its production, and we have no way of producing steel, cement or plastics at required scales without huge carbon emissions. Ultimately, Smil answers the most profound question of our age: are we irrevocably doomed or is a brighter utopia ahead? Compelling, data-rich and revisionist, this wonderfully broad, interdisciplinary guide finds faults with both extremes. Looking at the world through this quantitative lens reveals hidden truths that change the way we see our past, present and uncertain future.

''Een ideaal boek om te genezen van het idee dat de energietransitie een relatief simpel proces is. Smil schrijft terecht: er zal minder veranderen dan we denken.'' Maarten van Rossem ''Je kunt het eens of oneens zijn met Smil [...] maar je kunt hem beter niet negeren.'' The Washington Post ''Dit boek biedt de fundamentele basis om de grootste uitdagingen van deze tijd op te lossen.'' Bill Gates Door de gevolgen van klimaatverandering wordt er harder dan ooit geroepen om snelle veranderingen in onze levenswijzen en productiemethoden. Maar hoe realistisch zijn de claims dat zulke veranderingen haalbaar zijn? Vaclav Smil verdiept zich in zeven fundamentele onderwerpen die ons voortbestaan en onze welvaart bepalen. Zijn mantra: voordat je problemen effectief kunt aanpakken, moet je eerst de feiten kennen. Van energie en voedselproductie tot en met globalisering en risicomanagement: Zo zit de wereld in elkaar biedt de broodnodige realitycheck. Op basis van de nieuwste wetenschappelijke inzichten beantwoordt Smil de meest cruciale vraag van onze tijd: zijn we onherroepelijk gedoemd of ligt er een mooiere toekomst in het verschiet? Wie door Smils kwantitatieve lens naar de wereld kijkt, komt tot nieuwe inzichten waardoor de blik op ons verleden, heden en onze toekomst blijvend verandert.

"Vaclav Smil is my favorite author… Numbers Don't Lie takes everything that makes his writing great and boils it down into an easy-to-read format. I unabashedly recommend this book to anyone who loves learning."--Bill Gates, GatesNotes From the author of How the World Really Works, an essential guide to understanding how numbers reveal the true state of our world--exploring a wide range of topics including energy, the environment, technology, transportation, and food production. Vaclav Smil's mission is to make facts matter. An environmental scientist, policy analyst, and a hugely prolific author, he is Bill Gates' go-to guy for making sense of our world. In Numbers Don't Lie, Smil answers questions such as: What's worse for the environment--your car or your phone? How much do the world's cows weigh (and what does it matter)? And what makes people happy? From data about our societies and populations, through measures of the fuels and foods that energize them, to the impact of transportation and inventions of our modern world--and how all of this affects the planet itself--in Numbers Don't Lie, Vaclav Smil takes us on a fact-finding adventure, using surprising statistics and illuminating graphs to challenge conventional thinking. Packed with fascinating information and memorable examples, Numbers Don't Lie reveals how the US is leading a rising worldwide trend in chicken consumption, that vaccination yields the best return on investment, and why electric cars aren't as great as we think (yet). Urgent and essential, with a mix of science, history, and wit--all in bite-sized chapters on a broad range of topics--Numbers Don't Lie inspires readers to interrogate what they take to be true.

From one of the world's leading experts on the history of energy, a rigorous examination of the transitions that structure our modern world--and the environmental reckoning that will mark its success or failure. What makes the modern world work? The answer to this deceptively simple question lies in four "grand transitions" of civilization--in populations, agriculture, energy, and economics--which have transformed the way we live. Societies that have undergone all four transitions emerge into an era of radically different population dynamics, food surpluses (and waste), abundant energy use, and expanding economic opportunities. Simultaneously, in other parts of the world, hundreds of millions remain largely untouched by these developments. Through erudite storytelling, Vaclav Smil investigates the fascinating and complex interactions of these transitions. He argues that the moral imperative to share modernity's benefits has become more acute with increasing economic inequality, but addressing this imbalance would make it exceedingly difficult to implement the changes necessary for the long-term preservation of the environment. Thus, managing the fifth transition--environmental changes from natural-resource depletion, biodiversity loss, and global warming--will determine the success or eventual failure of the grand transitions that have made the world we live in today.

Wat onthullen cijfers over de toestand van onze wereld? Vaclav Smil, de favoriete wetenschapper van Bill Gates, geeft antwoord op actuele en urgente vragen over energie, het milieu, technologie, transport en voedselproductie. Waarom moeten we diesel voorlopig nog niet afschrijven? Hoeveel wegen alle koeien ter wereld (en waarom zou je dat moeten weten)? En wat maakt mensen gelukkig?Cijfers liegen niet laat je met fascinerende voorbeelden en verhelderende illustraties anders naar de wereld kijken. Je komt te weten hoeveel mensen er nodig waren om de Pyramide van Cheops te bouwen, waarom Nederlandse mannen de langste ter wereld zijn en waarom elektrische auto''s (nog) niet zo goed zijn als we denken.Vaclav Smil maakt duidelijk dat feiten ertoe doen en daagt je uit om de cijfers in de juiste context te plaatsen. Want cijfers liegen niet, maar welke waarheid brengen zij eigenlijk aan het licht?''Er is geen auteur naar wiens boeken ik meer uitkijk dan naar die van Vaclav Smil.'' Bill Gates''Een van de belangrijkste mondiale denkers.'' Foreign Policy''Een van de meest vooraanstaande denkers ter wereld over de geschiedenis van innovatie en een meester in de statistiek (...) Er is geen andere wetenschapper die zo beeldend over getallen schrijft.'' The Guardian ''Een origineel denker.'' Sheila Sitalsing

A selection of 50 Slovak folk tales assembled from the collections of folklorist Pavol Dobsinsky. The translator seeks to preserve the poetic qualities of the originals, and the book includes an introduction to the genres of the folktale and the specifics of Slovak tales.

Every human activity entails the conversion of energy. Changes in the fundamental sources of energy, and in the use of energy sources, are a basic dimension of the evolution of society. Our appreciation of the significance of these processes is essential to a fuller understanding of world history. Vaclav Smil offers a comprehensive look at the role
