Dog with lady


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! Anonymous
It's not the triviality, it's the emptiness of it that bothers me. Bryan Taylor
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
It is better to be roughly right than precisely wrong. Maynard Keynes
 

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
This calculation is not intellectual masturbation: there's no orgasm. Anonymous
There are many big Buts here... I like big Buts. 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
 
EDQNM is not rigour, unless you mean rigor mortis. Ian Abel
I wouldn't say these are theoretical arguments... I would call them arguments. François Rincon
