HD and the Void
I pick a topic I want to know more about and dig into it for a year. 2017 is all about space! I'll look at anything that sends me down a research tangent. I do take requests, I don't keep it formal, I do my research, I don't like describing complex math but I do try. Wander with me into the cat’s-cradle tangle of society, history, science, and anything I thought was cool to mention.
