"Waves of emotion change faster than the weather- but they follow patterns..." said Layla, casually brushing back her blonde hair.

"Yes, like waves on a pond- but those patterns change unpredictably when a pebble is tossed into the pond." said Mark.

"Yes, that's true- but the changed wave pattern is still a solution of the wave equation for the pond- just a different solution from the one before." said Layla in return.

"But if you can't predict how long a wave pattern will last, you can't predict much of anything!" said Mark.

Layla stirred in her chair.

"But what if we enlarge our system to include all information- that is suppose there really are no pebbles beyond our system, only unknown influence from the part of the pond we cannot see- then we would have one endogenous solution of the wave equation for all time- we just wouldn't know which one because we can't see all of the pond- we can only make educated guesses about which solution we are looking at based on the part of the wave pattern we can see." said Layla. And then she stirred her coffee with a silver spoon as she contemplated her imprecise analogy.
