If science is as slow as you say how do you explain the expansion of scientific knowledge during the past 100 years compared to all of history? Maybe we just have a lot more scientists walking around in the dark tripping over things. Your reliance on anecdotal evidence of accidental discovery as an accurate picture of scientific method suggests you're a person that walks only where the is light. You may never come to understand how 'scientific method' has and will continue to light your path. Instead you'll probably use that newly aquired light to dig up more anectodtes to to support your misguided belief.
