A Factful Guide

How to Feed the World

'There is no author whose books I look forward to more' Bill Gates 
 
'A fascinating deep dive...a wonderful fact-based tour of our food system, past and present. It opens up plenty of interesting debates on what to do next to feed 10 billion people without wrecking the planet' Hannah Ritchie, author of Not the End of the World 
 
In this ambitious, myth-busting book, leading scientist and internationally bestselling author Vaclav 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 is food waste a colossal 1,000kcal per person daily, and how can we solve that? Could we all go vegan and be healthy? Should we? How will we feed the ballooning population without killing the planet? 
 
How to Feed the World shows how 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. Ultimately, this data-based, rigorously researched guide explains how we will survive and thrive long into the future.

There is no author whose books I look forward to more than Vaclav Smil

A compelling, fascinating, and most important, realistic portrait of the world and where it's going

There is perhaps no other academic who paints pictures with numbers like Smil . . . The nerd's nerd

A fact-filled, punchy book . . . Smil's fascination with numbers is infectious

‘How to Feed the World had a lot to teach me – and I’m sure it will teach you a lot, too. It challenges readers to think differently about a problem we thought we understood’

Another masterpiece from one of my favourite authors

BILL GATES on the New York Times bestseller HOW THE WORLD REALLY WORKS

Very informative and eye-opening in many ways

HA-JOON CHANG, author of 23 Things They Don't Tell You About Capitalism on the New York Times bestseller HOW THE WORLD REALLY WORKS

The word "polymath" was invented to describe people like him

Smil’s art is that he immerses readers rather than overpowering them, while delivering clear takeaway messages: that we must learn to do more with less, that we ought to be wary of any radical solutions, and that we must accept that any gains will be gradual

Concise and erudite . . . How to Feed the World is weighted with statistics, but there is something light and irresistible about the way Smil structures his argument and propels his narrative . . . The breadth of Smil’s knowledge is as impressive as the depth

Vaclav Smil is Distinguished Professor Emeritus at the University of Manitoba. He is the author of over forty books on topics including energy, environmental and population change, food production and nutrition, technical innovation, risk assessment, and public policy. No other living scientist has had more books (on a wide variety of topics) reviewed in Nature. A Fellow of the Royal Society of Canada, in 2010 he was named by Foreign Policy as one of the Top 100 Global Thinkers.

How It Explains the World

Size

'There is no author whose books I look forward to more' Bill Gates 
 
The New York Times bestselling author returns with a mind-opening exploration of how size defines life on Earth. 
 
Explaining the key processes shaping size in nature, society and technology, Smil busts myths around proportions - from bodies to paintings and the so-called golden ratio - tells us what Jonathan Swift got wrong in Gulliver's Travels - the giant Brobdingnagian's legs would buckle under their enormous weight - and dives headfirst into the most contentious issue in ergonomics: the size of aeroplane seats. 
 
It is no exaggeration to say this fascinating and wide-ranging tour de force will change the way you look at absolutely everything. 
 
&lsquo;Vaclav Smil is a phenomenon with an appetite for facts over prejudice and fashion. Essential reading for anyone who cares about the future&rsquo; Lord Norman Foster

Vaclav Smil is a phenomenon with an appetite for facts over prejudice and fashion. Essential reading for anyone who cares about the future

An endlessly entertaining career through fascinating territory

Both informative and entertaining . . . I suspect that many Physics World readers would be delighted to find this book waiting for them under the Christmas tree. Indeed, it would be perfect reading material for anyone who enjoys a mathematical analysis of the world around them

In a world of specialized intellectuals, Smil is an ambitious and astonishing polymath who swings for fences . . . They're among the most data-heavy books you'll find, with a remarkable way of framing basic facts

There is perhaps no other academic who paints pictures with numbers like Smil

Vaclav Smil is Distinguished Professor Emeritus at the University of Manitoba, Canada.

A Scientist’s Guide to Our Past, Present and Future

How the World Really Works

* THE NEW YORK TIMES BESTSELLER * 
 
 'Another masterpiece from one of my favorite authors . . . If you want a brief but thorough education in numeric thinking about many of the fundamental forces that shape human life, this is the book to read. It's a tour de force' BILL GATES 
 __________ 
 
 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 and that our societies have been steadily increasing their dependence on fossil fuels, making their complete and rapid elimination unlikely. Drawing on the latest science and tackling sources of misinformation head on - from Yuval Noah Harari to Noam Chomsky - ultimately Smil answers the most profound question of our age: are we irrevocably doomed or is a brighter utopia ahead?

 'Very informative and eye-opening in many ways' HA-JOON CHANG, author of 23 Things They Don't Tell You About Capitalism 
 
 'If you are anxious about the future, and infuriated that we aren't doing enough about it, please read this book' PAUL COLLIER, author of The Future of Capitalism

Ha-Joon Chang, author of 23 Things They Don't Tell You About Capitalism

It is reassuring to read an author so impervious to rhetorical fashion and so eager to champion uncertainty . . . Smil's book is at its essence a plea for agnosticism, and, believe it or not, humility - the rarest earth metal of all. His most valuable declarations concern the impossibility of acting with perfect foresight. Living with uncertainty, after all, "remains the essence of the human condition." Even under the most optimistic scenario, the future will not resemble the past

A grumpy, pugnacious account that, I would argue, is intellectually indispensable in the run up to this year's COP27 climate conference in Egypt. In short, How the World Really Works fully delivers on the promise of its title. It is hard to formulate any higher praise

You can agree or disagree with Smil - accept or doubt his 'just the facts' posture-but you probably shouldn't ignore him . . . In Smil's provocative but perceptive view, unrealistic notions about carbon reduction are partly, and ironically, attributable to the very productivity that societies achieved by substituting machine work, powered by fossil fuels, for draft animals and human laborers

This accessible and witty book cuts to the chase of what we need to know

If you are anxious about the future, and infuriated that we aren't doing enough about it, please read this book

Paul Collier, author of The Future of Capitalism

"I am neither a pessimist nor an optimist; I am a scientist," Smil writes in the introduction, with typically Smilian swagger. In fact, he is more of a numberist, a polymath with a gift for rigorously crushing complex data into pleasing morsels of information

Smil's meticulously researched words are for anyone who wants his priors reexamined and feathers ruffled

Ambitious and eye-opening . . . provides valuable insight as opposed to the agenda-pushing rhetoric commonly found in mainstream scientific literature. Data-rich, informative and eye-opening, How the World Really Works is a captivating read

Canadian polymath Vaclav Smil taught at the University of Manitoba for half a century. In this brilliant book, he does the hard work of crunching complicated data to present a clear and surprising picture of how our world - especially our physical world - really does work

Chrystia Freeland, Deputy prime minister and minister of finance, Canada

This is a compelling read. It uses science and practical examples to clearly illustrate the kinds of resources we are consuming on this planet today - and the quantities, too. It lays bare how demanding the changes will be in our daily lives if the green transition in energy away from fossil fuels is to be achieved. It also makes clear how far humanity is lagging behind the Paris Agreement's goal of limiting the global temperature rise to 1.5 degrees Celsius. Getting China and India fully on board with this is absolutely critical if climate warming is to be even moderately tamed

Olli Rehn, Governor, Bank of Finland, and governing council member, European Central Bank

Numbers Don't Lie

'My favourite author has done it again. Numbers Don't Lie is by far his most accessible book to date, and I highly recommend it to anyone who is curious about the world. I unabashedly recommend this book to anyone who loves learning' Bill Gates 
 
Is flying dangerous? How much do the world's cows weigh? And what makes people happy? 
 
 From Earth's nations and inhabitants, through the fuels and foods that energize them, to the transportation and inventions of our modern world - and how all of this affects the planet itself - in Numbers Don't Lie, Professor Vaclav Smil takes us on a fact-finding adventure, using surprising statistics and illuminating graphs to challenge lazy thinking. Smil is on a mission to make facts matter, because after all, numbers may not lie, but which truth do they convey? 
 
'Smil's title says it all: to understand the world, you need to follow the trendlines, not the headlines. This is a compelling, fascinating, and most important, realistic portrait of the world and where it's going' Steven Pinker 
 
 'The best book to read to better understand our world. It should be on every bookshelf!' Linda Yueh 
 
'There is perhaps no other academic who paints pictures with numbers like Smil' Guardian 
 
Vaclav Smil is Distinguished Professor Emeritus at the University of Manitoba.

No other living scientist has had more books (on a wide variety of topics) reviewed in Nature. A Fellow of the Royal Society of Canada, in 2010 he was named by Foreign Policy as one of the Top 100 Global Thinkers. This is his first book for a more general readership.

The human mind soaks up the images and narratives conveyed by the press, but they are a highly nonrandom sample of reality: the lurid, the sudden, the photogenic. Smil's title says it all: to understand the world, you need to follow the trendlines, not the headlines. This is a compelling, fascinating, and most important, realistic portrait of the world and where it's going

The best book to read to better understand our world. Once in a while a book comes along that helps us see our planet more clearly. By showing us numbers about science, health, green technology and more, Smil's book does just that. It should be on every bookshelf!

Linda Yueh, author of The Great Economists

One of the world's foremost thinkers on development history and a master of statistical analysis . . . The nerd's nerd

A book for anyone confused by statistics or dubious of data in a world where numbers seem to mean everything and nothing. Vaclav Smil's new book reveals why diesel isn't as bad as you think, how much food is really being wasted, what actually makes people happy, and much more.

Outstanding perspectives on the world we live in providing context on mankind's challenges ranging from demographics through globalization, innovation and the environment

Sarah Riopelle, Senior portfolio manager at RBC Global Asset Management

Is flying dangerous? How much do the world's cows weigh? And what makes people happy? 
 
From earth's nations and inhabitants, through the fuels and foods that energize them, to the transportation and inventions of our modern world - and how all of this affects the planet itself - in Numbers Don't Lie, Professor Vaclav Smil takes us on a fact-finding adventure, using surprising statistics and illuminating graphs to challenge lazy thinking. 
 
Packed with 'Well-I-never-knew-that' information and with fascinating and unusual examples throughout, we find out how many people it took to build the Great Pyramid, that vaccination yields the best return on investment, and why electric cars aren't as great as we think (yet). There's a wonderful mix of science, history and wit, all in bite-sized chapters on a broad range of topics. 
 
Urgent and essential, Numbers Don't Lie inspires readers to interrogate what they take to be true in these significant times. Smil is on a mission to make facts matter, because after all, numbers may not lie, but which truth do they convey?

How it Explains the World

Explore how speed influences every aspect of life on Earth, from the slow grind of geological processes and the fleeting lifespans of organisms to the astonishing speed of light and the remarkable adaptations of creatures like the swift antelope and the soaring albatross. In this ambitious and wide-ranging ideas book, internationally bestselling author Vaclav Smil uncovers the intricate connections between speed, nature, and human innovation. 
 
With counterintuitive insights, such as how erosion actually accelerates mountain growth, Smil challenges long-held myths. For example, Smil debunks the notion that our modern lives are accelerating at an unprecedented pace: the rapid adoption of mobile phones – from 0% in 1983 to 90% in 2002 (19 years) – is like the spread of earlier technologies such as radio (22 years), colour television (24 years) and even microwave ovens (17 years). 
 
In SPEED, Smil combines his trademark compelling statistics with insightful analysis to take readers on a captivating journey through the vast timescales of Earth’s history and the complexities of modern life. He explains how we measure speed and reveals the theoretical limits that shape our societies, offering a thought-provoking exploration of the forces that define our world. This eye-opening book encourages readers to see speed’s vital role in everything around us.
