TOPICS

FUSION:

  • Drift-wave turbulence: zonal-flows, coherent structures, shear and all that
  • Plasma physics at (and in) the Edge
  • 3D and EM (or not)
  • GK numerical algorithms
ASTRO:
  • (Kinetic) turbulence, reconnection, dynamo, pressure anisotropies, microinstabilities and all that
  • Exteme astrophysics: same as above, but at higher energies
JPP



If you know exactly what you are going to do, what is the point of doing it? Pablo Picasso

Every line in your calculations ends with "=0". You are not making much progress!
Kate Hammett
We don't do the calculation because we don't know the answer, we do it because we have a conscience. Bryan Taylor
Let's change the resolution on the Unknown. Gabe Plunk
Let me put it differently: suppose we had a reactor... Per Helander
Working together takes more than one person. Bill Dorland
We can't do ultraviolence to that square bracket. Ian Abel
Field lines are forever. Bryan Taylor
This is not really an ill-posed problem, this is not a problem at all. Paul Dellar
I am just doing mathematics at the moment, but it is mathematics that has some point. Bryan Taylor
The equivalent of God in MAST is MHD, which is global and all powerful. Anthony Field
I've got a fishbone coming up. Tim Horbury
We have crossed all the i's and dotted all the t's. Job's a good'un. Ian Abel
Let us not jump in front of the bandwagon! Alex Schekochihin
It's not the triviality, it's the emptiness of it that bothers me. Bryan Taylor
Never take 0 for an answer. Alex Schekochihin
This is a very inefficient way of achieving nothing. François Rincon
We Hankel all the way in and then Hankel all the way out. Joseph Parker
For the sake of fairness, let me mention that some people have objections to this, none of which are particularly valid. Chris Chen
Yes, Steve, you have always known what we have only just figured out. Alfred Mallet
This is more or less right. Perhaps less. Alfred Mallet
You go ahead with your argument. I'll think. Steve Cowley
Too simple? At the end of my talk, you will beg for simplicity! Andrey Beresnyak
The point is not the point! Anonymous
This is why I am presenting this here and nowhere else: nothing is solved! Ian Abel
It is better to be roughly right than precisely wrong. Maynard Keynes 

This calculation is not intellectual masturbation: there's no orgasm. Anonymous
Previous studies of this problem have been either unsatisfactory or limited in scope.---What  is the difference between these?---This means either wrong or irrelevant.
Anatoly Spitkovsky, Michael Medvedev and Steve Cowley (in conversation)
I don't give a damn about astrophysics, explain to me what is going on. Anatoly Spitkovsky
Have you subtracted the baby with the bathwater? Steve Balbus
 
This is not rigour, unless you mean rigor mortis. Ian Abel
I wouldn't say these are theoretical arguments... Let's just call them arguments. François Rincon
You can never be too happy with the state of your closure. Amitava Bhattacharjee
For this plot, 1 is 6.--- Weeell, not even. Steve Cowley and Steve Balbus
Это качественное объяснение недостаточно качественное. Eugene Churazov
If you mean it seriously, this is actually a very good question. Minhyong Kim
This paper is a tour de farce. Ian Abel
What is modelling? You run a simulation, you compare. If it coincides, great! If it doesn't coincide, fuck! Felix Parra
We are stuck at x=0. Felix Parra
I have seen papers where the student wasn't the problem. Michael Hardman
There has been a lot of fascinating work on this subject, most of it kind of boring. Philipp Kempski
These simulations show more or less exactly the same thing. Francesco Califano
So now you want us to drop everything we are doing and start worrying about what the big questions are?! Ian Abel
Oh dear, I thought I had some conclusions. Nuno Loureiro
I've got my little fingers inside this plasma. Steve Cowley
Words will play a big role in this talk. Dmitri Uzdensky
Everything that can be done should be done---and that's the astrophysical attitude. Michael Medvedev
What I will talk about is not low-hanging fruit. A lot of people have looked at this. There is no fruit here at all.---Is it sour grapes? Michael Medvedev and Nuno Loureiro
[these quotes are mostly from Oxford plasma seminars and the Vienna meetings]

The workshop will be held at
Wolfgang Pauli Institute, Faculty of Mathematics, University of Vienna,
Oskar-Morgenstern-Platz 1, 1090 Vienna, Austria
All seminars are in Seminar Room 08.135 (8th floor)

Hotels: Deutschmeister (very close by and perfectly adequate), Pension Ani-Falstaff (non-nonsense super-affordable student option)
Hotels with AC: Harmonie (somewhat self-indulgent, comes at a noticeable additional expense to you), Bellevue (a 15-min walk, but both nice and affordable)
Please contact Ms Ramona Bluma (ramona.bluma at  univie dot  ac dot  at) to arrange accommodation
