    Cover of The psychology of invention in the mathematical field

    The psychology of invention in the mathematical field

    Jacques Hadamard · 1945

    Thoughtful and articulate study of the origin of ideas. Role of the unconscious in invention; the medium of ideas — do they come to mind in words? in pictures? in mathematical terms? Much more. "It is essential for the mathematician, and the layman will find it good reading." — Library Journal.

      For a introspective view of "aha" I really recommend the enjoyable Hadamard "The Psychology of Invention in the Mathematical Field."

      I've heard it being called Focussed Mode and Diffuse Mode, as described here - https://fs.blog/focused-diffuse-thinking/

      Bret Victor links to this book called Psychology of Invention in the Mathematical Field, which talks a lot about this too - http://worrydream.com/refs/Hadamard%20-%20The%20psychology%2...

      If you find this sort of thinking interesting, definitely also check out "The Psychology of Invention in the Mathematical Field" by Jacques Hadamard.

      The Psychology of Invention in the Mathematical Field by Jacques Hadamard, himself a mathematician is not scientific but a good source of anecdotes and systematic attempts at introspection.

      I find that 'stepping away' from the details after immersion for a few days and allowing the pieces to re-align themselves does seem to pay benefits, even with the mundane and practical problems I need to solve. I agree with the grandparent post that alcohol is not the only de-focusing agent around.

      > "intimidating"

      Exactly.

      /speculation

      There is a point where one starts to see "behind" the symbols. It's a strange sensation, as if one could understand the ideas in a non-verbal way. The symbols become optional. Intimidation crawls back before curiosity at this point.

      An amazing book on the subject is:

        "Hadamard - The psychology of invention in the mathematical field"
