What have we got here?

figure

(a) nobody gives a damn, Lisa;
(b) phase portraits of quadratic polynomial vector fields;
(c) phase portraits of polynomially quadratic field vectors;

Anybody?

As a physicist, I can say with genuine professional authority that those are fields.

And a lot of them have freaky singularities that make them damned near physically impossible as magnetic, electric, or gravitational fields.

If this were physics, I'd be really curious about them, but as it's mathematics, I'm sure they really don't represent anything my tiny brain can imagine.

well you sound as if you're kind of on the track anyway---care to venture a guess?
