It's been a long time since I had to do a research paper. When I was fresh out of high school, most of my teachers frowned upon the internet as a source, because the internet wasn't quite the integral part of society it is today.
Next week, I have to turn in a topic for a research paper for a physics class. It can be on any topic that has to do with physics in any way at all, and I've chosen to do it on theoretical energy sources and propulsion systems for future space travel. I know the kinds of sources I want, I'm just not really familiar with where to find them.
So my question for the Asylum is: do you know of any reputable science journals/magazines or any other legitimate sources of scientific information that may be helpful to me?
