Answers to simultaneity / time dilation questions

Hi guys!

So, I think this is my first message to Rebecca's physics students this year. I'm a little embarrassed it took me so long to say hello, but things out at CERN have been pretty busy for me recently.

Anyway, this week I'm posting the answers to the first two sets of questions. If you found the one on simultaneity a little abstract, I don't blame you. It's tough to find reasonable questions before we've developed any of the mathematics, but hopefully you'll agree that it gets better as we go.

Oh, and a standing invitation: feel free to leave me comments at any time, on any post; don't worry that I won't see them--I get notified automatically. Especially for the answers; if there's something you don't understand, or something you think I messed up, write me and let me know!
