Chaos

IDEA 1
Simple rules can create chaos
Gleick tells the story of chaos theory, a new science that emerged in the 1960s and 1970s. It showed that simple, fixed rules can produce behaviour so complex that it looks random.
IDEA 2
A rounding error changed science
Gleick describes how the meteorologist Edward Lorenz ran a computer weather model and found that a tiny change in starting numbers produced completely different results. This showed how sensitive some systems are.
IDEA 3
Small causes can have big effects
Gleick explains the butterfly effect, the idea that a tiny disturbance can grow into a large change over time. This means long-range weather forecasts will always have limits. Precise prediction becomes impossible.

IDEA 1
A lonely boy became a genius
Gleick describes Newton's lonely childhood in Woolsthorpe, England, where his father had died before he was born and his mother left him with his grandmother. He grew up solitary, curious and secretive.
IDEA 2
Plague years brought discoveries
When plague closed Cambridge University, Newton returned home and made major discoveries in mathematics, optics and gravity. These years were extraordinarily productive. Gleick presents this quiet time as one of the most productive periods in the history of science.
IDEA 3
He invented calculus
Newton developed calculus, a mathematical tool for studying change and motion. He later quarrelled with Leibniz over who invented it first. Gleick shows that this quarrel became bitter, because each side wanted credit for the same idea.

IDEA 1
Information shapes human history
Gleick tells the story of information, from early writing and drums to computers and the internet. He argues that information has become the central substance of the modern world. Every era found new ways to send it.
IDEA 2
Drums once carried messages
Gleick describes African talking drums, which sent complex messages over long distances by imitating the tones of speech. Drummers added extra phrases to avoid confusion, a way of building in redundancy.
IDEA 3
Early machines dreamed of computing
Gleick describes Charles Babbage's plans for calculating engines and Ada Lovelace's insight that such machines could handle symbols, not just numbers. Their ideas were far ahead of their time. Computers later fulfilled them.
