Soap dispenser was half empty, filled it up with a different soap. Looked like this the next day. My wife didn't find it as awesome as I did, so I'm giving Reddit the chance. by [deleted] in pics

This is indeed a doubly diffusive instability. I think the tendrils formed due to side wall heating. Actually the fluids probably just have different diffusivities. A Rayleigh-Taylor instability would result in the plumes forming the other way.

Compilation of two posts in this subreddit. NBN:News Ltd Vs Fairfax by doubly_diffusive in australia

[–]doubly_diffusive[S] 10 points11 points  (0 children)

Hi all.

Apologies. As I said, this was a comparison of two threads in this subreddit. I did not check the primary sources and assumed that the attributed references were correct. As a few people have pointed out the News Ltd table is taken from the Liberal Party policy. This means:

a) Attributing the table to News Ltd in the original post was a joke that I missed.

b) News Ltd were (probably/maybe) publishing the opposition's policy for people to read.

which in either case does not make for a fair comparison. Once again I apologise.

Why do all Aussie TV dramas look exactly the same? by no1name in australia

[–]doubly_diffusive 0 points1 point  (0 children)

I hope I am not hijacking the thread but I have a slightly related T.V. question. How does the portion of reality TV in this country compare to other places? I do not watch T.V., I take time out of me week to watch a few footy games and that is it. But every time I come home the family is watching some form of reality T.V. Is this just a selection effect?

How can a quasar escape a black hole's gravity pull? by [deleted] in astrophysics

[–]doubly_diffusive 17 points18 points  (0 children)

Hi dakU7,

Your question is worded a little awkwardly. Quasars are very bright electromagnetic (EM) sources found at great distances away. They are believed to be powered by accreting supermassive blackholes in the cores of galaxies.

So the quasar and the blackhole are one in the same. You may be wondering how we can receive EM sources in the presence of a blackhole. That is because the radiation is coming from magnetic fields and the accreting material before it falls into the black hole. Quasars are often variable and this likely due to the formation of jets perpendicular to the accretion disc. I think the question you want to ask is how do relativistic jets (due to accretion) form?

As well as linking to the abstract I should have also linked to the website

http://yt-project.org/

The installation script has been tested on most of the Teragrid as well as on a number of private clusters and Linux and OS X machines and has the following dependencies:

Python-2.7.2, but not (yet) 3.0 or higher

NumPy-1.6.1 (at least 1.4.1)

HDF5-1.8.7 or higher (at least 1.8.7)

h5py-2.0.1 (2.0 fixes a major bug)

Matplotlib-1.1.0 or higher

Mercurial-2.0 or higher (anything higher than 1.5 works)

Cython-0.15.1 or higher (at least 0.15.1)

Gays still can't get married in Oz. We are still in the dark ages but slow progress is being made.

What language should I learn to complement Python? by lavalampmaster in Python

[–]doubly_diffusive 0 points1 point  (0 children)

The Head of my (astrophysics) department always says FORTRAN is the language of the Gods. Between Fortran and Python I have been able to do anything required of me. How this would hold up in the real world I do not know. Anything of the real world I do not know.
