On Tuesday, I read Mia a story from the latest Highlights magazine that talked about galaxies and stars moving and led us to a long discussion of thermodynamics and the Big Bang. I quickly learned that I was not able to explain the Big Bang in a way that was remotely understandable to an almost four year old, so we picked up a library book. Actually, we got several, the Big Bang, the moon, astronauts, and one about all the planets in the solar system. The Big Bang book was great, she got quite a bit out of it and I even learned a thing or two. The only problem is that it led to an hour-long discussion of quantum mechanics, and I know even less about that than I do about thermodynamics. I can't believe that I am having these conversations with my preschooler. I can't believe her new favorite book is the one about "the planet that got kicked out." (The solar system book was published pre-dissing of Pluto.) And I can't believe that she is now composing songs about the big bang and the origins of the cosmos. Who would ever have guessed that kids were actual people? Certainly not me before I had one of my own.
