you know exactly what you are going to do, what is the point of doing
it? Pablo
Picasso He goeth furthest who knows not whither he is going. Oliver Cromwell 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 What is the point? The point is not the point! Anonymous This is why I am presenting this here and nowhere else: nothing is solved! Ian Abel This calculation is not intellectual masturbation: there's no orgasm. Anonymous |
It is
better to be vaguely right than exactly wrong. Carveth Read (usually attributed to Maynard Keynes) 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 & 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 & Steve Balbus This qualitative explanation is not of sufficient quality. 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 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.---How about sour grapes? Michael Medvedev & Nuno Loureiro In order to have a disappointment, you first have to have an appointment.
