Naomi Alderman explores the thinking of the Buddha, who, as a young prince, ventured outside the palace walls and began his journey towards enlightenment.

Siddhartha Gautama lived in a life of rarefied luxury until an encounter with suffering changed everything for him. He became the Buddha, the awakened one, urged self-transformation and profoundly shaped the world we live in. But did his many insights come from thinking, as such, or something else altogether?

Albert Einstein was an international pop star of science who urged the US government to build an atom bomb. Naomi Alderman gets into one of the most famous brains of all time.

Einstein rewrote our understanding of universe. He imagined hitching a ride on a light beam and pursued his famous 'thought experiments' to remarkable ends. He was a man who never swam with the tide. Despite a lifelong commitment to pacifism, in 1939, Einstein signed a letter urging the US government to speed up work on the development of a nuclear bomb. Naomi finds out why.

Lise Meitner was a world-class physicist, who saw what others could not. She recognised nuclear fission – the splitting of the atom, the powerful energy released – before anyone else. Naomi Alderman finds out how.

Women weren't even allowed to attend lectures at the University of Berlin, when Meitner moved there in 1907. She began her career in a basement workshop, kept away from male students, and went on to build an unimpeachable reputation for scientific precision and brilliance. Her discovery of fission made the atom bomb possible, but she refused to have anything to do with the Manhattan Project.

Naomi Alderman dives into the amazing intellect of John von Neumann, physicist, mathematician, economist, computer scientist – a visionary who predicted the rise of artificial intelligence decades ahead of time.

As a child, von Neumann could recite the telephone directory and crack jokes in Ancient Greek. He waltzed into the Manhattan Project and solved a problem that had frustrated other top scientists for months. His work on game theory underpins the modern world, from defence strategies to dating apps. But, for all his serious intellectual contributions, von Neumann was a party animal, who did his best thinking surrounded by people and noise.

Niels Bohr said, 'Anyone who is not shocked when they first come across quantum theory cannot possibly have understood it.' Naomi Alderman investigates the remarkable insights of a scientific genius.

Bohr is the man who figured out the structure of the nucleus at the centre of the atom, recognising that the quantum world of tiny particles behaves very differently to the tangible, everyday world around us. He built a scientific family around him, mentoring some of the greatest theoretical physicists of the twentieth century.

Naomi Alderman explores the multifaceted mind of J Robert Oppenheimer, scientific lead on the Manhattan Project, a vast, top secret scheme to build the world's first atomic bombs in World War II.

The Project was a remarkable feat of human intellect with a real, devastating human cost. It required close cooperation between the US military and a group of world-leading scientists. In many ways, Oppenheimer was a puzzling candidate for the job. He was brilliant, but fuelled by self-loathing. A physicist, he was also a student of philosophy and mysticism, interested in left-wing radical politics. Oppenheimer built the bomb, but later called the weapon's industry "the devil's work". His legacy, like the Manhattan Project itself, is infinitely complex.

Darwin asked big questions. His theory of evolution transformed our understanding of life on Earth. But Naomi Alderman discovers that he did it by looking at small things and tiny changes that other people had overlooked. From earliest childhood, he’d been a collector – pocketing shells, coins, minerals, bits of pottery and rooftiles – and his travels on HMS Beagle allowed him to amass a vast collection of specimens and observations that he and others would puzzle over for decades.

Samuel Johnson was living proof that a person can be extremely messy and disorganised but still do work of great worth. He compiled and almost single-handedly wrote an English dictionary that changed the language for good. ‘Dictionary Johnson’ established the spelling and meaning of many words; he looked at etymology; he poked fun and cracked jokes. He lived hand to mouth, writing for money, and helped establish the modern literary world.

Naomi Alderman examines the intelligence and sharp humour of an ancient Greek historian known as Pamphila of Epidaurus. She was a female historian working in a society that believed women were constitutionally unsuited to the rational and peculiarly masculine task of recording facts for posterity. She wrote thirty-three volumes of her famed Historical Commentaries from her home. She wrote for fun, organising her material in a free and easy mix, like ‘embroidery’. We have none of her original writings, just reported fragments, but she gave us cultural history as we know it today, centuries ahead of time.

Naomi Alderman looks at the remarkable way Denis Diderot connected ideas and people. In 18th-century Paris, he edited one of the very first encyclopaedias: twenty-eight volumes with tens of thousands of articles on everything from the concept of liberty to cutting-edge medical research, the manufacture of silk stockings and a recipe for apricot jam. Diderot was the perfect man for the job – energised by veering from one subject to the next and undeterred by fierce opposition from the Church or even a government ban on the entire project.
