The Disappearing Spoon: 8 key ideas
The core ideas of The Disappearing Spoon, each in under a minute, written in our own words. Want the full depth? Get the book.
- IDEA 1 OF 8
The periodic table tells stories
Kean argues that the periodic table is full of stories about people, wars and discoveries.
Each element has a history beyond its chemical properties. Kean tells them with humour. Each chapter is lively.
- IDEA 2 OF 8
A spoon can melt in tea
Kean describes gallium, a metal that melts at a low temperature.
A spoon made of it would disappear in hot tea, a favourite trick of chemists. It is a classic practical joke.
- IDEA 3 OF 8
Mendeleev saw the pattern
Kean describes Dmitri Mendeleev's creation of the periodic table and his bold predictions of missing elements.
His success made the table a powerful tool. Gaps in his table were later filled.
- IDEA 4 OF 8
Curie studied radioactivity
Kean describes Marie Curie's work on radioactive elements.
Her discoveries won her fame but also exposed her to harmful radiation. She won two Nobel Prizes for her research on these elements.
- IDEA 5 OF 8
Scientists raced to make elements
Kean describes researchers in places like Berkeley creating new heavy elements.
These efforts were linked to Cold War competition. Rival laboratories argued over who found them first and what to name them.
- IDEA 6 OF 8
Some elements are deadly
Kean describes poisonous elements such as thallium and cadmium.
Their effects on people show the dangers of chemistry. Some were used deliberately as poisons, while others harmed whole communities. Both stories are told.
- IDEA 7 OF 8
One village gave many names
Kean describes Ytterby in Sweden, where several elements were discovered.
Their names reflect the village's surprising importance. A single mine there produced rare earth minerals. Four elements were named after it.
- IDEA 8 OF 8
Chemistry shapes history
Kean argues that elements have influenced wars, economies and medicine.
The table is a record of human curiosity and ambition. Behind every element are human stories of courage, rivalry and error.
