>>4. Popper disagreed with Heisenberg’s uncertainty principle.
Heisenberg's principle has more to do with the interference between observer and observed than anything else - and the place to focus is using attempts to prove the principle wrong, each failed attempt making the principle less likely to be wrong - just like anything else. And there's still the possibility of interaction with some kind of as-yet unknown particle or force letting us know both position and momentum. A subatomic black swan, if you will.
Also, both induction and deduction have a place in the project of science (making a model of how the world works). Yes, attempting to disprove hypotheses is critical, but those hypotheses have to be generated somehow, as do more general theories based on those progressively-more-likely-true hypotheses, which in turn generate more hypotheses allowing attempts to disprove the theory. It's attempts to disprove all the way down (like turtles in Pratchett's Diskworld :-)
