ABSTRACT
Well, it's another fillin talk by one of the organizers. The
message is clear: we need talks! Please volunteer! We especially would like
to hear from students.
That said, I do have some new understandings about the
Parker's model of coronal heating based on a simple concept that we all
learned from our statistical mechanics classes: random walk. In this talk,
I will review the coronal heating problem and what we have done on it in
numerical simulations. I hope to show how we can understand these results
theoretically, based on the concept of random walk of the magnetic field
line footpoints on the photosphere (surface of the sun). I hope students
will at least get this out of this talk: a simple concept like random walk
we learned in our undergraduate studies can help understanding great unresolved
problems in physics.
