Solar physicists are the most bad-ass of all astrophysicists.<p>They are not afraid of unconstrained plasma fluid dynamics, which sends practically all other physicists and cosmologists fleeing in terror. It is considered extremely rude, even "career-limiting" to even mention plasma dynamics at a regular astrophysics conference.<p>Most physicists who do anything with plasma try desperately to stay within the stable envelope where the maths remain tractable. With good reason.
