At a time when Einstein had gained international recognition, quantum theory culminated in the late 1920’s statement of the Uncertainty Principle, which says that the more precisely the position of a particle is determined, the less precisely the momentum is known in this instant, and vice versa. The above phrasing of the principle is a succinct version of the mathematically precise uncertainty relation that Heisenberg published in 1927. Since the momentum of a particle is the product of its mass and velocity, the principle is sometimes stated differently, however, its meaning remains the same: The act of measuring one magnitude of a particle, be it its mass, its velocity, or its position, causes the other magnitudes to blur. This is not due to imprecise measurements. Technology is advanced enough to hypothetically yield correct measurements. The blurring of these magnitudes is a fundamental property of nature
Gross mistatement?..... really? More of a paraphrase. Of course I am sure that along with economics your field of study is also Quantum Physics.

Too bad your source carries the same misconception. It has nothing to do with "measurement blurring" anything. The attributes of quantum level matter are ALWAYS "blurred" in their natural because they are a probability (wave) function. They are in all states at all times, just with varying probability. The only thing that observation can do is remove "blurriness", not increase it, via the collapse of the wave function into discrete properties.
Actually I did plan on majoring in Physics early on and had 6 semesters of it (4 required, 2 elective). I realized however that my talents lie in the practical, not the theoretical.
BTW, the above is so far off it even talks about "velocity" which is not defined for quantum particles.
