Is faith in science comparable to religious faith? Scientists aren't dogmatic in the sense that they review their theories whenever they are contradicted by new experiments, but still, they have faith that their methods lead them to a better understanding of the world.
If you ask the question at this level of generality, the answer is probably "yes". This is not necessarily very profound; if you get general enough you would expect the two to have something in common: "Are science and religion comparable in that both are human endeavors?"; "Are science and religion comparable in that both are intended to convey information?"
In particular, yes, scientists do engage in their pursuit because they believe that it will lead them to a better understanding of the world. The question then is whether it's apt to call it "faith". Scientists have accomplished breathtaking things, so there's certainly abundant evidence that science leads them to a more powerful position from which to manipulate the world. But there's always doubt that running that RNAseq experiment will really tell you something meaningful about the interaction partners of CREB, and generally as a personal matter it's faith that this whole thing's eventually going to work and turn out that keeps scientists going.
You cannot conclude from this that science and religion have the same sorts of guarantees behind the robustness of their claims, only that people like to do things that they believe in, and scientists are people.
