My seven year old begged to stay up late tonight so that he could watch "The Ghost Particle", a Nova program on PBS about neutrinos. Despite being very tired, he watched the whole thing intently.
Some (well, a lot) of the concepts were pretty arcane. My wife asked him during the show if he was following it. I interjected that the show gave a good portrayal of the scientific method. He interrupted - "Yes, I got that...."
I'm proud of that boy.
