Does repeated "experimentation and observation" make it immune from the errors or blunders?
Of course not. Just like NOT doing those things won't make you immune either.
After how many experimentation the result understood/interpreted will be considered 100% correct?
I'm going to say never. By definition, using the scientific method, we can NEVER know anything to a 100% certainty. But they'll still probably know a lot more than the people who try to argue them with guesswork.
Has it ever happened that the result understood to be correct was later found to be erroneous?
ALL the time. I think it's still a mistake on your part for thinking that scientists go around thinking that they are 100% infallible and correct in all things. That's not the point of science.
The word "repeated" shows that doubt was there in the very first place, and it was only out of faith that the exercise was continued. Science is, therefore, the fruit of faith.
Rofl. You're talking about the individual motivations of people doing experiments here... A subjective assessment about subjective assessments.
But even then, repeating something DOES NOT show doubt in itself, you just think it does. Your logic is a bit weak there. But of course there's probably doubt a lot, too. I'm quite confident that many experiments have been performed specifically FROM doubt: As in, when trying to falsify something, and it turns out to be "correct" instead...
You then assume it requires faith, but i can counter you by saying that it doesn't require faith at all. No further explanation needed.
It is not a "battle" with faith, rather it is battle with doubt. Human conscience reject doubt, faith generates peace and progress .
That doesn't sound like a very factual or solid statement with evidence behind it at all. Do i need to spell it out aloud? Ok: You are mistaking your subjective assessment for an objective fact. Firstly, you haven't shown any doubt in the first place...
So, it is faith and faith alone in the "experimentation and observation" that science, the scientists and the people dealing in science that science "works" and continues its endeavors. Please
Right? Please
Nope.
I still think it's funny you somehow think that science is some actual physical thing. Science works simply because as a philosophy, it's made to work inside its own context, like math for example. Math works, right?
Right? Please.
Regards
Double nope.
TLDR: I still think it's a massive leap of faith to consider science faith based.
