A natural fractal is a natural element that can be described by fractal geometry. Clouds, mountains, circulatory system, the coastlines or snowflakes are natural fractals. This representation is approximate, since the properties ascribed to the ideal fractal objects such as infinite detail, have limits on the natural world.

Characteristics

Frost crystals formed naturally on cold glass illustrate fractal process development in a purely physical system

A fractal often has the following features:

It has a fine structure at arbitrarily small scales.

It is too irregular to be easily described in traditional Euclidean geometric language.

It is self-similar (at least approximately or stochastically).

It has a Hausdorff dimension which is greater than its topological dimension (although this requirement is not met by space-filling curves such as the Hilbert curve).

It has a simple and recursive definition.

Because they appear similar at all levels of magnification, fractals are often considered to be infinitely complex (in informal terms). Natural objects that are approximated by fractals to a degree include clouds, mountain ranges, lightning bolts, coastlines, snow flakes, various vegetables (cauliflower and broccoli), and animal coloration patterns. However, not all self-similar objects are fractals—for example, the real line (a straight Euclidean line) is formally self-similar but fails to have other fractal characteristics; for instance, it is regular enough to be described in Euclidean terms.

Images of fractals can be created using fractal-generating software. Images produced by such software are normally referred to as being fractals even if they do not have the above characteristics, such as when it is possible to zoom into a region of the fractal that does not exhibit any fractal properties. Also, these may include calculation or display artifacts which are not characteristics of true fractals.

GeOgEbRa

GeoGebra is a free interactive mathematical software education in colleges and universities. Its creator Markus Hohenwarter, the project began in 2001 in Salzburg University and continued on Atlantic University, Florida.

It is basically a "geometric processor" and a "Processor algebraic", ie a collection of interactive mathematical software meets geometry  algebra and calculus, and therefore can be used also in physics, business projections, estimates  strategic decision and other disciplines.

GeoGebra is written in Java and therefore available on multiple platforms.

GeoGebra constructions can be made from points, lines, rays, segments, vectors, tapered ...etc. - by direct use of tools operated with the mouse or the entry of commands into the input bar with the keypad or by selecting from the list available

TOEFL

The TOEFL (Test Of Inglés as a Foreign Language) is a test that measures fluency and knowledge in the English language. Based on the English spoken in the United States, the company is developed by ETS, as well as other tests such as GRE. The certificates provided by the test are recognized internationally, especially by educational institutions, which are those for which is primarily directed.

The test can be performed throughout the world, approved by ETS facilities and preparations to host the exam. The price of the test is not the same throughout the world.

Blogger Vs Moodle

Blog and Moodle are two different platforms, although can be used in educational settings is huge difference. Many people start writing in a blog and then discover Moodle, but initial experience is helpful.

Moodle is a learning sofwere but they can only occupy those in the group.

Blogger is more casual to publish any information.

Yes you can link the blog to Moodle, it would have to do at what level, but I think can bind, for Moodle requires a system of income security, although Sure, you can create courses open to guests who do not require password.
