The electron cloud is often represented with a fuzzy outline because electrons can be found in different locations within the space around the atom at any given moment. What we mean is that though each electron has a fixed energy level in which it "lives" in the cloud, it is not confined to a fixed physical location or position. Electrons are always in motion, and they can be found a little closer to an atomic nucleus one moment, and a little farther away in the next moment. Use the link below to a related question to learn a little more.
It's simply called the electron cloud, and it does look fuzzy in diagrams. We don't really know what it looks like, but we do know that it consists of various energy levels, and the electrons move through it very quickly. Based on valence shell electron repulsion theory, we can predict the three-dimensional geometry of the space they occupy, but ultimately, we just can't see them because they're so small.
I suppose on some atom models the electron cloud would be called "fuzzy".
No, there really aren't any pictures of the electron cloud of an aluminum atom. Atoms are too small for conventional pictures. There are drawings of the electron clouds of atoms, but they're just "fuzzy shapes" because the location, or, rather, the probable location, of electrons cannot be precisely stated. It can only be given as a probability density function - an "indefinite area where an electron is most likely to be" as it is hanging around in orbit. The shapes of the electron clouds vary as we look at them from atom to atom. A link is provided to a post introducing the viewer to the basic shapes.
"Uncertainty Principle". He didn't say that the position can't be precisely determined. He said that the position and the momentum can't both be precisely determined at the same time. The more precisely you determine one, the more fuzzy the other becomes at the same time.
Because it best fits the experimental data. From a layman's perspective (the layman being me, not necessarily you), the reasoning is thus: Heisenberg's Uncertainty Principle states that we cannot know both the position and the trajectory of a particle, because in the act of observing the particle we will have altered at least one of those qualities. What we can then deduce about the position of an electron (its 'orbit,' if you will) is not a precise set of values but a range of probabilities as to where that electron will be at a given point in time. That range, represented graphically, describes a fuzzy-edged set of possible locations, in the shape of a hollow sphere (thus "cloud"), at a distance from the atomic nucleus which is determined by the energetic state of that particular electron.

Stars appear to twinkle and are fuzzy due to the earths atmosphere
An electron doesn't have specific orbital path about an atomic nucleus. They move in specific energy levels that we identify as specific electron orbitals. But recall that the area where the electrons hang out is called the electron cloud. It's a "fuzzy zone" where electrons may be found. Electrons don't have specific routes about any atomic nucleus.

"Cloud" ought to give you a clue.Very, very small objects simply do not behave the same way that objects on the scale we're used to do. When you look at a bowling ball, it looks (and feels, and acts) like it has a hard edge that's well-defined.Electrons aren't like that. We can't even say with certainty where an electron is; it behaves in some ways as if it's lots of places at once, and even when we can narrow it down to a smaller region, it can "jump" from that region to another one without ever seeming to pass through the space in between. The best we can do is talk in terms of probabilities, and while the probability for an electron in an atom is highest for the region near the nucleus of that atom (well, at least relatively near ... within an Angstrom or two), the probability that it's several feet ... or miles ... or light-years ... away is not zero (it's just very close to zero). So we can't draw a sharp line and say "the electron is definitely inside here". Given that, it makes more sense to depict the line as "fuzzy", which better conveys the idea "the electron is probably somewhere inside here ... we're about 90 (or 95, or 99) percent sure of it ... but it might be outside".
None. An oxygen atom has a roughly spherical nucleus which is surrounded by a fuzzy cloud of electrons.

fuzzy graph is not a fuzzy set, but it is a fuzzy relation.
Fuzzy wuzzy had no hair, fuzzy wuzzy wasn't fuzzy was he.
fuzzy wuzzy had no hair... therefore he cannot be fuzzy
