My Christian friends I have met through blogging, Aussiebirder, just put out a very interesting and applicable application for faith. Please check out this blog:

The most interesting observation as a scientist that I have made over my years of birding and photographing birds is that of capturing what is termed the leap of faith. This phenomena is usually only observed in small passerines (tree perching birds) and not so much in larger species where much more effort is required to become airborne. The above photo was my first observation, taken of a Lord Howe Island Golden Whistler male leaping off a branch, into the air, quite confidently, with wings closed. My camera had caught something my limited human eye had not.
