A few days ago, I was scheduled to meet with a collaborator of mine in the early afternoon. She called me in the late morning and said, “I’m observing the fact that I seem not to have moved, and I’m wondering what to do about it.”
“Well,” I said, “it seems to me that you have two options. First, you could operate from an understanding of the Heisenberg Uncertainty Principle, which states that the mere fact of observation changes the thing being observed. Or second, you could move.”
When I type it now, it doesn’t seem that funny, but I promise that in the moment it was, as they say, a laff riot.
Really, I’m telling this story as a way to introduce this link, but I can’t for the life of me come up with a graceful segue.
