• There is a perverse side of me that would love to discuss the Heisenberg’s Uncertainty Principle with Britney Spears. The famous scientist Werner Heisenberg taught us that the very act of measuring and observing phenomena (in his case, subatomic particles) disturbs and alters that phenomena.

Now class — I mean Britney — the same goes for reality TV. In the debut episode of “Britney and Kevin: Chaotic” (8 p.m., UPN), Britney promises to show us clips of videos of her “document(ing) (her) first romantic moments with Kevin (Federline).” But Britney, how romantic could these moments have been if you were “documenting” them?
