I love getting reader questions as blog prompts, and given the sort of people I hang out with, I get some really fascinating ones! Here's a question that Riia sent in for the blog. I've known Riia through the SCA (Society for Creative Anachronism) for a very long time and have been following her professional travels and adventures from Alaska to California to Tasmania (am I remembering that correctly?) to Italy to Sweden doing research with lasers and garnets (among other things).
