There is no prescribed route to follow to arrive at a new idea. Der er ikke foreskrevet rute til følge for at nå frem til en ny idé. You have to make the intuitive leap. Du er nødt til at gøre den intuitive spring. But the difference is that once you've made the intuitive leap you have to justify it by filling in the intermediate steps. Men forskellen er, at når du har foretaget de intuitive spring du nødt til at retfærdiggøre det ved at udfylde de mellemliggende trin. In my case, it often happens that I have an idea, but then I try to fill in the intermediate steps and find that they don't work, so I have to give it up. I mit tilfælde, sker det ofte, at jeg har en idé, men så jeg prøver at udfylde de mellemliggende trin og se, at de ikke arbejde, så jeg er nødt til at give det op. ~Stephen W. Hawking ~ Stephen W.
