Arthur C. Clarke's 2001 Diary (excerpts)

May 28, 1964. Suggested to Stanley that "they" might be machines who regard organic life as a hideous disease. Stanley thinks this is cute and feels we've got something.

May 31. One hilarious idea we won't use. Seventeen alien, featureless black pyramids riding in open cars down Fifth Avenue, surrounded by Irish cops.

June 20. Finished the opening chapter, "View from the Year 2000," and started on the robot sequence.

July 1. Last day working at Time/Life completing Man and Space. Checked into new suite, 1008, at the Hotel Chelsea.

July 2-8. Averaging one or two thousand words a day. Stanley reads first five chapters and says "We've got a best-seller here".

July 9. Spent much of afternoon teaching Stanley how to use the slide rule -- he's fascinated.

July 11. Joined Stanley to discuss plot development, but spent almost all the time arguing about Cantor's Theory of Transfinite Groups. Stanley tries to refute the "part equals the whole" paradox by arguing that a perfect square is not necessarily identical with the integer of the same value. I decide that he is a latent mathematical genius.

July 12. Now have everything -- except the plot.

July 13. Got to work again on the novel and made good progress despite the distraction of the Republican Convention.

July 26. Stanley's birthday. Went to the Village and found a card showing the Earth coming apart at the seams and bearing the inscription: "How can you have a Happy Birthday when the whole world may blow up any minute?"

July 28. Stanley: "What we want is a smashing theme of mythic grandeur."

August 1. Ranger VII impacts on moon. Stay up late to watch the first TV close-ups. Stanley starts to worry about the forthcoming Mars probes. Suppose they show something that shoots down our story line? [Later he approached Lloyd's of London to see if hc could insure himself against this eventuality].

August 6. Stanley suggests that we make the computer female and call her Athena.

August 17. We've also got the name of our hero at last -- Alex Bowman. Hurrah!

August 19. Writing all day. Two thousand words exploring Jupiter's satellites. Dull work.

September 7. Stanley quite happy: "We're in fantastic shape." He has made up a 100 item questionnaire about our astronauts, e.g. do they sleep in their pajamas, what do they eat for breakfast, etc.

September 8. Upset stomach last night. Dreamed I was a robot, being rebuilt. In a great burst of enorgy managed to redo two chapters. Took them to Stanley, who was very pleased and cooked me a fine steak, remarking: "Joe Levine doesn't do this for his writers..."
