Not sure if I'm allowed to post resources here. I'm not affiliated with this site or its book, it's simply a good resource I use for low-level research. Some things aren't 100% accurate, but the large majority of it all is. Covers common writing mistakes on everything from biology to rock-climbing, to realistic knife fights. Just thought you guys might want to see it. http://dankoboldt.com/science-in-scifi/
