Pipelined motherhood

Not long ago a friend, referring to my second child (who just turned 1), asked me how my second round of motherhood was treating me. He tried to use a computer metaphor for it, so he put it as "how is serial motherhood going?" Then he immediately admitted that this metaphor was inaccurate. It's not really serial, because I'm raising two children, not one at a time. You could say it's parallel, but that doesn't convey the idea of going from one child to two. So, pausing for a bit, he decided it could be called pipelined motherhood. Since I haven't heard about pipelined architecture, which (as a very oversimplified explanation) lets computers run tasks in parallel by starting them at different times, I thought about it in UNIX pipe terms. So I asked: "Do you think I feed one child the output of the other?"

Cute analogies

A few posts ago I was musing about the best ways to introduce scientific ideas in science fiction, to explain them in terms vivid enough to intrigue a reader, instead of slowing down the action. In Sunday's New York Times magazine I found an inspiring example of how it can be done. (I put the particularly memorable sentence in bold.)

Where Protons Will Play

To be sure, the article I'm referring to is a science fact article, not fiction, but I think there's something to be learned from this little perl of explanation. I'm not being sarcastic -- this excerpt seems silly and clever at the same time:

[F]locks of protons will be made to zip around the tunnel in opposite directions at nearly the speed of light. Then they will be forced to crash into each other, with (it is hoped) spectacular results for physics.

Physicists, you see, learn about the subatomic world by smashing things together and then looking at the debris. Imagine a midair collision between two watermelons; it would make quite a mess, but nothing very interesting would result. Suppose, though, you get two protons to collide head-on. If they are moving fast enough, the energy of their collision, converted into mass à la Einstein's E=mc2, will produce a shower of new particles. (It would be as if colliding watermelons splattered into a shower of pineapples, blueberries, mangoes and more exotic fruits.)
