Survival of the infinitely fittest

Our world is big and messy, but we agree
that certain facts are objectively true:
Earth is not flat, despite a minority
of people still dispute this hitherto.

What else, we all concur a billiard ball
hit by a cue with ordinary force,
will never just go through a masonry wall
without leaving a hole in a brick course.

But in the microscopic quantum realm
particles can be in two places at once,
so how does objectivity unwhelm?

It's natural selection: At a glance,
the more observers look at the same cat,
the more consensus will be formed hereat.

This Darwinian revue
was known to occur for atoms and all that.
We prove it holds for infinite "cats" too.

Every little quantum helps

Today we’re gonna play a guessing quiz. First, pick a little marble from your drawer. Then push it into a mystery box, whose core is like a maze of many paths. Now, whizz, Look at the ball when it comes out and guess: Which way, inside the box, did it go through? Was it path number one, or three, or two? Let’s try and assess your chances of success. If your marble’s a cheap, generic brand, the various paths won’t have that much effect. But, if you choose a rather high-spec ball, With every different turn, during its roll, a distinct shine the sphere’s going to reflect. Just spot the change and win! Do you understand? Let me briefly expand and give you the tagline (pardon the garble): Every quantum resource is a good marble.

The Office Aide

This is a story which may sound familiar: A man, called Bob, had lots of work to do. However, his condition was peculiar, His brains were tied, and his energy too. One day, a keen co-worker joined the office, Resourceful, with energy to spare, But with no tasks to do. Her name was Alice. She noticed Bob was swamped in despair. Then she proposed a deal: She’d do the thinking And give him clear instructions. Bob, in turn, Could sort stuff at his desk with zero sweating. They would share any revenue in return. And it worked out! They did a stellar job. It was such a dream team: Alice & Bob.
