BUILDING NEW WAYS OF "PAYING ATTENTION": Interdisciplinar y Astronomy, Physics, and Statistics
Ingrid Daubechies[1]: ``But I looked at it differently. A change of paradigm. Well, paradigm, I never know what that means. A change of ... a way of seeing it. A way of paying attention.''

Ways of Paying Attention: Astronomy Perspective to 1980 After a good beginning, Isolated

· · · · ·

Started out together (Kepler, LaPlace, ...) Interesting independent methods, i.e. MC BUT ISOLATED: "Astronomers and Physicists know a few methods (Chi-Square, FFT, KS....) and use it for EVERYTHING" All assumes Gauss-Normal holds "Well it's not exactly wrong..." --- BUT sometimes it is!
