1. IDEA 1 OF 8

   Curiosity made life an adventure

   Feynman, a Nobel Prize-winning physicist, tells funny stories from his life that show his endless curiosity.

   He treated every problem, from fixing radios to learning new skills, as a puzzle worth solving for fun.

2. IDEA 2 OF 8

   He fixed radios by thinking

   As a boy, Feynman repaired radios by reasoning about what was wrong rather than following instructions.

   People were amazed that he could fix things by thinking. The story shows that he liked to understand problems for himself instead of following fixed rules.

3. IDEA 3 OF 8

   He cracked safes at Los Alamos

   While working on the atomic bomb at Los Alamos, Feynman enjoyed picking locks and cracking safes containing secret documents.

   He did it to show how weak security was. The stories show his playful nature as well as his curiosity.

4. IDEA 4 OF 8

   He learned to draw

   Feynman decided to learn drawing and became good enough to sell his art.

   He enjoyed exploring a completely different skill. He shows through this story that trying new skills for fun can be rewarding.

5. IDEA 5 OF 8

   He played drums in Brazil

   Feynman learned to play bongo drums and joined a samba band in Brazil.

   He loved music and new experiences. He shows that he enjoyed learning from people outside science, and found joy in taking part in their world.

6. IDEA 6 OF 8

   Understanding beats memorising

   Feynman criticised education that taught students to memorise without understanding.

   He described Brazilian students who could recite facts but not apply them. He argues that real learning means being able to use an idea, not just repeat it.

7. IDEA 7 OF 8

   Beware cargo cult science

   Feynman warned against cargo cult science, research that looks scientific but lacks real rigour.

   He compared it to people building fake runways hoping planes would land. He wanted scientists to check their work honestly, and not to copy the look of science without the substance.

8. IDEA 8 OF 8

   Scientists must be honest

   Feynman argued that scientists must be honest, especially with themselves.

   Self-deception, he warned, is the first trap to avoid. He wanted scientists to look hardest at their own mistakes before they blamed other people for errors.
