I've spent a lot of time soul searching after having some academic "failures" in the previous semesters, and what I found is that often when I'm not studying, it's not because I can't study, but it's because the book we're using is unreadable to me. For example, after sailing through Calculus...

Hello. Longtime reader, first time poster. I'm 28, and graduated from a decent school in Philadelphia in 2005, though I wasn't a very good student--mostly a lack of maturity and discipline. Having obtained a BS in Information Systems has led to work in various IT careers that haven't been too...

Someone gave me the argument... In other words, a complex system allowing for intelligent life is unlikely a mere coincidence. Thus, suggesting a "creator". Myself being scientifically immature, the only counter point I could think of is: we don't know all the possible combination of...
