My favorite books about the big ideas that changed our world

Why am I passionate about this?

I’ve always been fascinated by great ideas, even wrong ones. As a child, I read a ‘science’ book that proposed that atoms are like solar systems inhabited by electron-sized people and animals. It was bonkers but it got me thinking about astronomy, biology, and particle physics and I retain that fascination today (though I no longer believe in tiny people living inside atoms). But ideas, even wrong ones, can be endlessly fruitful. Einstein came up with the idea of quantum entanglement ‘spooky action at a distance’ as he called it, supposedly as an example of where quantum mechanics goes wrong. A few decades later, experiments proved quantum entanglement was real.

Life Is Simple: How Occam's Razor Set Science Free and Shapes the Universe

By Johnjoe McFadden,

Book cover of Life Is Simple: How Occam's Razor Set Science Free and Shapes the Universe

What is my book about?

Life is Simple is about Occam’s razor, the simplest and most powerful idea that anyone has ever had. It is simply(!) that if you have lots of explanations for say a light in the night sky, then you should choose the simplest – it’s an airplane – so long as it works. The razor is named after William of Occam, a cool medieval friar who disproved the standard ‘proofs’ of God and accused the Pope of heresy. My book follows his razor’s tracks as it cuts through medieval baloney to establish modern science and its subsequent wielding in the hands of Copernicus, Newton to Einstein or Higgs. It remains a cornerstone of modernity and the most powerful weapon against pseudoscience, conspiracy theories, and fake news.

The books I picked & why

Book cover of Sapiens: A Brief History of Humankind

Johnjoe McFadden Why did I love this book?

Sapiens: A Brief History of Humankind is, first of all, a great read and page-turner. 

Harari takes us on a journey from the emergence of Homo sapiens in East Africa to the present day, covering key milestones such as the Agricultural Revolution, the rise of civilization, empires, and technology. Through insightful analysis, he delves into topics like the development of language, the impact of myths and religions, and the role of technology in shaping our species and our lives.

This thought-provoking book challenges readers to question the fundamental nature and future trajectory of humanity. Was agriculture a ‘good thing’? What about technology? Or money? Harari may not have all the answers but he has some great questions.

By Yuval Noah Harari,

What is this book about?

100,000 years ago, at least six human species inhabited the earth. Today there is just one. Us. Homo sapiens. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations and human rights; to trust money, books and laws; and to be enslaved by bureaucracy, timetables and consumerism? And what will our world be like in the millennia to come?

In Sapiens, Dr Yuval Noah Harari spans the whole of human history, from the very first humans to walk the…


Book cover of The Silk Roads: A New History of the World

Johnjoe McFadden Why did I love this book?

Tired of Western-orientated histories of the world? Then take a trip along the Silk Road with Peter Frankopan.

His book is a captivating exploration of the history of the world but with its frame of reference centered in the great cities of the East, such as Baghdad or Peking, and, of course the Great Silk Road that linked much of the world in a single trade route that connected civilizations from East to West, facilitating the exchange of goods, ideas, and cultures.

He highlights the pivotal role the Silk Road played in shaping global history, from the rise and fall of empires to the spread of religions and the transmission of knowledge. Fascinating stories and insights, such as the West to East slave trade operated by medieval Rus tribes.

Book cover of The Malay Archipelago

Johnjoe McFadden Why did I love this book?

I love this book because it provides a great account of the theory natural selection, described as the greatest idea that anyone ever had, by its co-discover, Alfred Russell Wallace.

The Malay Archipelago describes what is now largely a lost world, the 19th-century Malayan Archipelago. Unlike Darwin, Wallace had to earn a living as a ‘fly-catcher’ to support his passion, travelling in native canoes rather than Royal Navy ships, and living with native people, rather than European aristocrats.

Wallace's book describes the geographical distribution of animals, the diversity of species, and his observations of the region's fauna and flora, illustrating how natural selection shapes organisms and ecosystems. But he doesn’t stop with the animals, he also gives us sympathetic portrayals of native people and their lifestyles.

What is this book about?

The Malay Archipelago is a book by the British naturalist Alfred Russel Wallace which chronicles his scientific exploration, during the eight-year period 1854 to 1862, of the southern portion of the Malay Archipelago including Malaysia, Singapore, the islands of Indonesia, and the island of New Guinea. The book describes each island that he visited in turn, giving a detailed account of its physical and human geography, its volcanoes, and the variety of animals and plants that he found and collected. At the same time, he describes his experiences, the difficulties of travel, and the help he received from the different…


Book cover of Wonderful Life: The Burgess Shale and the Nature of History

Johnjoe McFadden Why did I love this book?

This book brings alive, in startling details, the remarkable explosion of multicellular life in the Cambrian period.

600 million years ago, all life on Earth was unicellular microbes. A few tens of millions of years later and the world was teeming with a fantastic diversity of animals. Gould challenges the notion of a predictable and linear evolutionary path and argues instead that chance events and contingency played a crucial role in shaping the course of evolution.

But what I really love is Gould’s attention to detail. It’s said that “the devil is in the detail" and, in his book, Gould revels in the anatomical details of fantastically well-preserved and very strange animals, such as the bizarre Anomalocaris, from the Burgess Shale, their discovery, significance, and just how wonderful life can be.

What is this book about?

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived-a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.


Book cover of Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures

Johnjoe McFadden Why did I love this book?

Who would have thought fungi could be so fascinating and clever?

In this very easy to read but informative book, Sheldrake explores the intricate and symbiotic world of fungi and their invisible connections with plants and animals. From mycelium networks that connect plants underground to the potential of fungi in medicine, psychedelics, biotechnology, the book uncovers the hidden and remarkable abilities of fungi.

Sheldrake challenges our perception of fungi as mere decomposers or organic matter and reveals their immense impact on our planet. For my taste, Entangled Life does occasionally stray into wishy-washy mystical magic mushroom ramblings but Sheldrake’s engaging storytelling and scientific insights, Entangled Life offers a captivating journey into the interconnectedness of life through the lens of fungi.
