There isn't really much to "blindfoldely believe" in science. Science is about making conclusions and hypothesis based on observation and logic. If further observation is made, old theories are rejected or corrected.
Because of this, science is always changing.
In short: Science doesn't even "believe" in itself. Science is about doubt, not about belief.
We could say "believing" in science is the exact opposite of "blindly believing" in anything, because "believing" in science pretty much means accepting you don't know anything, and accepting that everything you think you know could eventually be found to be untrue.
Mate, again I tell you that there is no logic behind the principle of induction and, although we build logical models to suit the real world, there is no logical conection between our hypothesis and the real occurrences. Once we form a logical hypothesis, we can only "hope" it will help us predict something. And it not always does, and thus we need modify our hypothesis until they have a better chance of describing the real world (although probability is not a good answer to the problem of induction, but I won't get into that).
We can only be certain about rational truths, because following their logic, we find no contradictions. But nature around us is not part of us and therefore does not follow the same basic logic (or we have no knowledge of that logic) therefore we cannot say anything about it with certainty.
I know I am being too sceptical for my own good, but these are concepts that as a scientist you must control, because it is easy to make a mistake and say that because you "by chance" predicted something, will mean that you know (and knew) eveything relating that something.
