In honor of Valentine’s Day, a physics-themed poem I wrote a few years ago, about unrequited love.
I once took a measurement
It was a simple, two-body problem,
Solvable. Not Poisson’s mess.
Two particles, drifting, perhaps entangled.
I wanted to know two things:
Position, and momentum:
Where they were, and where they might go.
I perturbed the system
Like a good scientist, I interacted, and observed,
Added input, caused change.
Then I knew their positions.
They became tightly entangled,
And there was no way of knowing
Any way they could change.
I should have remembered:
In quantum systems
The observer is always involved;
And a three-body problem
Has no solution.
