Everything we have contact with could be a complete falsehood, so in that sense, science goes on the faith that every observable thing is actually...Being observed, I guess. There's faith in the scientific method (although that feels like having faith that your car, which has been working fine since you got it, will work fine the next time you start it), there's faith that other scientists won't try to somehow BS you (which is more of a capitalist consumer concern, I suppose). But I don't think we can comfortably apply concepts of faith to the day to day work that goes into scientific exploration. Although maybe in a broader sense, faith can enter into the work of science.
I'm not really comfortable with the paralleling of science and religion, though, because the spirit of science is pioneering, and the spirit of religion is not; science quests, religion knows. And so science has faith, in a sense, that we will never know everything about the physically observable, while religion has faith that it answers all of the spiritually knowable (feelable? Conceivable?). So it's pretty apples and oranges, in the first place; science is observation looking for answers (WTF? Why is that butterfly red and this one blue?) while religion is looking for something entirely different.
I do think that non-scientists have a religious faith in science, though. Or just your average Western consumer. I see infomercials all the time with foot doctors talking about something is good for my back, or anal proctologists selling me a diet. And people buy it because "a doctor said" or "a scientist said." I had to suffer on anti-depression meds mistakenly diagnosed for months as a kid because a doctor fucked up the prescription, and my folks bought what he was saying just because he was a doctor. So if we're gonna talk about faith in science, I think it makes more sense to talk about the laymen/women than the "clergy," if you know what I mean. I think scientists get that their endeavor requires certain (I would say faith-based) assumptions about the desire and potential for human progress and the knowability of the universes for the most part (because why do it if there isn't a belief, that at some point, we will understand it, if not put it to use for the betterment of humanity?), but folks who just like scientific stuff (like that FUCK YEAH SCIENCE shit on Facebook and stuff) just trust what they read without really investigating and think stars are pretty or something. Makes me think of all the hubbub about the Higgs boson; a lot of non-scientists I knew (not that I'm a scientist- I do poetry, criticism, education, and that stuff, which all compels me towards research- just had no fucking clue and parroted headlines. It was like hearing little kids repeat the political opinions of their parents without any understanding of it.
