Grade school text books are not the most reliable sources of scientific knowledge. I'm sure you know that. Are you just trying to score cheap rhetorical points?
How could I score cheap rhetorical points against someone who's mainstay of arguing his point is cheap shots and insults?
As far as the text book goes I was only referencing the "Scientific Method" that has been in use since Roger Bacon proposed it in the 1200's. Popper has decided to add to it, which is fair enough, however to say that the Scientific Method is dead and gone is a little over the top.
Thanks for asking, I hope I answered to your satisfaction.
