No pictures right now. While I'm getting my new computer up and running, it isn't there yet. And while maybe I could post some pre-2012 pictures and caption those I'm not at all sure I can successfully upload pictures to Dreamwidth so don't want to deal with that. I'll have more pictures sometime later. Meanwhile, this was on my humor blog this week, despite the fiasco.

Also, you know what? Let me post this here before the postscript. I wrote a heck of a big post for my mathematics blog and it gets into some real physics and diff eq and all that.

Trivia: In a Saturn V's Mode II abort the Apollo Service Module main engine lifts the Apollo capsule away from the second- and third-stages to get clear. Then on separation from the Service Module the Command Module rolls heads-up, to a full-life entry attitude. (The capsule's shape and mass configuration let it generate some lift.)
