Because I don't think we'll ever be together at a blackboard and I haven't drunk a beer since the Reagan administration. Sad as it is, the internet is my only current university.
Forget paddles and paddling.
Is a line not composed of points? If so, then any stagnation line is composed of stagnation points.
Consider an egg. Consider it moving through a fluid. This is a 3D space according to Euclid, or 4D according to Einstein, or 11D according to Witten.
Not considering boundary layer effects, what is the stagnation "geometry" on the frontal end of the egg? I don't think it's a line. I suggest, asymptotically, it's a point.
Back to paddles.
I accept the terminology and actuality of a stagnation line on a paddle face.
Much more reluctantly (without empirical proof), I will accept that a symmetrically spilling stagnation line will reduce paddle flutter vis-a-vis some other stagnation line.
What I have real difficulty accepting is that you can "force" this symmetrical spillage by gluing a ridge on a paddle face. Paddle face movements are too complex and changing in 3D and 4D for the spillage to maintain symmetry. (I don't believe Witten and his 11D supersymmetry.)
And if I had spilled more many decades ago, I might have finished majoring in physics instead of Budweiser.
