- IDEA 1 OF 8
Knowing a name is not understanding
Feynman recalls his father teaching him that knowing a bird's name in many languages tells you nothing about the bird.
Real understanding comes from observing what it does and asking why.
- IDEA 2 OF 8
Curiosity drives discovery
Feynman describes the joy of figuring things out as the real reward of science.
Prizes and honours mattered less to him than the pleasure of finding something new. Fun was his real motive.
- IDEA 3 OF 8
Los Alamos brought hard questions
Feynman reflects on working on the atomic bomb as a young scientist during the war.
He describes the excitement of the work and later doubts about what it led to.
- IDEA 4 OF 8
Beware cargo cult science
Feynman warns against research that copies the outward forms of science without its honesty.
He urges scientists to report everything that could prove them wrong, including results that do not fit.
- IDEA 5 OF 8
There is room at the bottom
In a famous talk, Feynman imagined building machines and writing information at the scale of atoms.
His ideas later inspired the field of nanotechnology. He even offered prizes to anyone who could build such tiny devices.
- IDEA 6 OF 8
A simple experiment exposed a failure
Feynman describes serving on the commission investigating the Challenger space shuttle disaster.
He showed with a glass of ice water that the shuttle's rubber seals lost flexibility in cold weather.
- IDEA 7 OF 8
Organisations can hide risks
Feynman argues that NASA's managers greatly underestimated the risk of failure compared with engineers.
He warns that organisations must not let public relations override technical reality. Nature, he said, cannot be fooled.
- IDEA 8 OF 8
Doubt is a strength
Feynman argues that it is fine, even valuable, not to know the answer.
Living with uncertainty keeps the mind open and is far better than believing things that may be false.
