An important name in optics, theoretical physics. Dropping the name here increases the modality of this exact uncertainty theory.
This article doesn't make much sense. Population sampling statistics do not involve immediately mutual effects, and I think that mutual measurement effect interaction has a role in further specifying the uncertainty. Here's hoping that the new equation is not simply the inequality after removing the "or greater than". It seems to me that the image analysis field has provided more food for thought on the same topic. One relevant concept in that field is the Fisher matrix.
The result is an expression that looks like Heisenberg's original relation, but gives the exact uncertainty in the measurements of position and momentum. Hall says it is an equation rather than an inequality, which is "a far stronger relation".
But it will still be an inequality. Nothing prevents you from having a more uncertain measurement than that allowed by the uncertainty relation, whatever that relation might be.

dp dx = h / (2 x pi) + y
See, I can do it too. ; )
BUMP for later read
"I find it remarkable that the Schrödinger equation no longer has to be god-given," says Wolfgang Schleich, who studies the foundations of quantum mechanics at the University of Ulm.
Don't let some of these people see that!
