The Pip is getting really into books these days, and SteelyKid has been into them for a good while now (she's four-and-a-half, after all...). At some point last week, she asked about my writing, so I got down a copy of How to Teach Relativity to Your Dog and showed her her name in the dedication, which she was tickled by (she now refers to it as "my book").
In which we look back on the ninth full year of this blog, and one of the most unpleasant incidents in the whole run, which nearly ruined what was otherwise a good year. ------------ This is probably going to be the longest of these posts, at least in terms of the number of links included-- I've got all of the worthwhile-looking posts open in tabs, and it comes to 82 total. I may ditch a few of them during the post-writing process, but we'll see how that goes.
In which we look back at a very political, perhaps excessively political year on the blog. ------------ I'm picking up the pace of my recap because I'd like to get through as much as possible before the actual tenth anniversary of the blog this Friday. I won't get through every year, but I'm going to try to do as many as I can.
"A truly good book teaches me better than to read it. I must soon lay it down, and commence living on its hint. What I began by reading, I must finish by acting." -Henry David Thoreau
I exchanged a bunch of emails a week or two ago with a journalist who was working on a story involving the possibility of faster-than-light travel. He wanted me to check some statements about the relationship between FTL and causality. FTL creates problems for causality, because if you have an object moving faster than light, there will be pairs of observers who see events involving the FTL object happening in different orders, which means somebody will see an effect happen before its cause.
