What is fractional dimensional space?

We introduce fractional flat space, described by a continuous geometry with constant non-integer Hausdorff and spectral dimensions. This is the analogue of Euclidean space, but with anomalous scaling and diffusion properties. Models of Quantum Gravity, Field Theories in Lower Dimen- sions, Fractal Geometry.

Can a dimension be a fraction?

However, fractal sets can be “infinitely crumpled”, so no matter how small a sphere you use, you still get a dimension larger than you might expect. With fractals there is no “small enough” (that should totally be a terrible movie tag line), and you find that they have a dimension that’s often a fraction.

What does fractional size mean?

Portion of a sample of sand lying between two size limits, the upper being the limiting and the lower the retaining mesh.

Why do fractals have fractional dimensions?

Fractional dimensions are very useful for describing fractal shapes. In fact, all fractals have dimensions that are fractions, not whole numbers. If a line is 1-Dimensional, and a plane is 2-Dimensional, then a fractional dimension of 1.26 falls somewhere in between a line and a plane.

Why are fractals useful?

Why are fractals important? Fractals help us study and understand important scientific concepts, such as the way bacteria grow, patterns in freezing water (snowflakes) and brain waves, for example. Their formulas have made possible many scientific breakthroughs.

What is fractional width?

Definition: a numerical quantity that is not a whole number (e.g., 1/2, 0.5). Example: If you require a shutter that is 60 1/2″, the height fraction is the 1/2″. If you need a shutter that is 60″ even, then select 0/0″ as the inch fraction.

How do you read fractional rule?

Simply count the number of spaces between graduations or marks contained within a single inch. If there are 16 the smallest fraction would be 1/16″, if there are 8 the smallest fraction would be 1/8″, etc..

Do fractals exist in nature?

Fractal patterns are extremely familiar, since nature is full of fractals. For instance: trees, rivers, coastlines, mountains, clouds, seashells, hurricanes, etc. Abstract fractals – such as the Mandelbrot Set – can be generated by a computer calculating a simple equation over and over.

What determines the number of dimensions of a fractal?

In the case of fractals the number of dimensions has to do (this is a little hand-wavy) with the way points in the fractal are distributed. For example, if you have points distributed at random in space you’d say you have a three-dimensional set of points, and if they’re all arranged on a flat sheet you’d say you have two-dimensional set of points.

What is the dimension of a snowflake in math?

The Koch snowflake, which is so messed up that it has a dimension greater than 1, but less than 2. That all said, when somebody (looking at you, all mathematicians) talks about fractional dimensions, they’re really talking about a weird, abstract, and not at all physical notion of dimension.

How many dimensions of space can you have?

The dimensions of space are either there or not, so while you could have 4 dimensions, you couldn’t have 3.5. This entry was posted in — By the Physicist, Math. Bookmark the permalink .

How do you know if a set is d-dimensional?

Way back in the day mathematicians figured that a good way to determine the “dimensionality” of a set is to pick a point in the set, and then put progressively larger and larger spheres of radius R around it. If the number of points contained in the sphere is proportional to R d, then the set is d-dimensional.
