comment How laminar or turbulent is air?
Turbulent state is defined for a flow, not a fluid. So you have to define what the air flow you want to consider? Flow around you as you walk? Flow around a candle or an incense stick? Cannot answer the question satisfactorily without more details.

comment How can these fluid dynamical smoke-ring phenomena be explained?
I will look into the second point more and maybe do some diagrams if I find the time...

comment Is the liquid/solid line infinite?
That's interesting although raises quite a few new questions. Your phase diagram shows that it becomes very difficult to have liquid phase above 10^9 Pa. Is that behavior (vertical solid-liquid line becoming nearly horizontal) specific to water? Can this 10^9 limit be estimated a priori from atomic quantities?

comment Is there a small enough planet or asteroid you can orbit by jumping?
Other problem: finding a perfectly spherical asteroid. Irregular shapes will make this a lot more difficult !

You don't necessarily come back to your original location after your jump. Any other ballistic trajectory is possible if your speed is below the escape velocity.

comment Flames with no gravity?
I might have more on this in a few days, but couldn't resist to answer something already. Let me know if specific points are not clear...
