A kaon

I am still thinking about particle physics. Things are getting 'curiouser and curiouser.'

Stenger was one of the first few people to see the tracks left by a kaon (for instance, a particle talked about as the fusion of an anti-strange and a down quark). Tracks, however, like those left by a fox in the snow, are what are seen after the fox is gone not while the fox is around.

The length of a kaon track (ignoring relativistic effects) is 10^-15 seconds long. So this particle does not exist for very long. If I think of the track a little more, then I notice that the track has footprints in it. The first set of footprints is the footprints of the down quark going forward in time. Right next to these footprints are the footprints of the anti-strange quark coming the other way. The footprints are right next to each other. They are apparently held next to each other by a depression in the snow-the nuclear strong force.

Where these quarks come from and where they go after this little stroll down the same trail in the snow, I don't know. Why the antistrange appears at the right time and does the pas de deux with the down, I also do not know.

Can anyone help me with some comprehension?
