The 7-year-old Uncertainty Principle (7yoUP) states that you may observe any number of 7-year-olds in your yard at an instant in time, but you can never actually know how many 7-year-olds are in your yard. You can know the *identity* of some of the 7-year-olds in your yard, or you can know the *position* of some of the 7-year-olds in your yard, but you can never know all of the properties of all of the 7-year-olds in your yard. Which is to say, you cannot observe the 7-year-olds in your yard without fundamentally affecting the system itself.
This is due to the 7-year-old Singularity, which tells us that 7-year-olds often fail to be well-behaved.
Therefore, when you observe two 7-year-olds in your yard, it is probably safest to assume there are an infinite number of 7-year-olds in your yard, moving at such high speeds and/or behaving so erratically as to be essentially unobservable.
I’d better win the fucking Nobel Prize for Mathematics or Physics or Parenting for this observation, I tell you. Because I swear to God, within FOUR SECONDS, one seven-year-old boy has become five seven-year-old boys. And I **don’t know where they come from**. One moment they’re not there, and then POW! There they are.
I’m pretty sure this is a power one could tap for evil, nefarious purposes. Like, by feeding any number of the seven-year-olds some cola and lick-m-aid.
