        @AmenZwa I am sure Acton knew what he was doing when he picked that book title. (In fact, in the original edition of the book, the title was ostensibly just "Numerical Methods That Work", and the "Usually" was in a faded shade of gray, like he was trying to sneak it in.)

            @tpfto This is, as a whole, a pleasantly opinionated book.

              @nxskok I find that Acton is a little like Velvel Kahan (he of IEEE floating point standard fame) or Edsger Dijkstra: you don't always have to agree with what they wrote, but you should at least give them some serious thought.

                  @tpfto my take with this kind of thing is "the author has done some serious thinking about these issues, so if I'm going to disagree with them, I'd better have a good reason".

                      @kbob I don't know how appealing it would be to non-specialists, but let me just say that it's one of the books I read because I really like reading it (e.g. I'd read it before bedtime), as opposed to just needing to refer to it for an application (though I've done that for this book, too).

                        maybe I am totally wrong, but wasn't this once very influential book sort of about using the computer as a partial substitute for thought ?

                          It has been a good long while since I looked at Tukey, but what I took away from his body of work back then (setting the FFT algorithm aside) is that even the simplest tools can be used to reveal a lot about data (which he then amply illustrated in that book you display, e.g. stem-leaf plots). Just like Tufte, he does not strike me as the sort who'd surrender his capability to think and make sense of things to the computer.
