Now that I see it works...

I want to keep up with the books I've been reading alone, as well as the ones Obie and Eli and I have been reading. Maybe other stuff - who knows?

So. First entry. We are currently reading 'The Time and Space of Uncle Albert,' although last night Obie was being his contrary self and I was tempted to toss it in the bath. But we managed to finish chapter 1 before either one of us cried.

I think I'm enjoying it - it's very reminiscent of 'George's Secret Key to the Universe,' in that it is really just a physics lesson pretending to be a story. But I'm wondering about the actual physics part of it. According to Uncle Albert, light can't be considered to be light unless it is moving. And not only just moving, but moving relative to anyone who is watching. So you can't catch up to it, because then you'd be moving at the same speed, and so it would appear to you that the light was no longer moving, AND so it would no longer be 'light'. Or something? I know that most physicists believe that you can't go the speed of light, but is this really the theoretical underpinning? Because it seems kind of weak to me.

But hey, we're only on chapter one.
