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

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.

Viva la vida lyrics

Viva la Vida (Coplay)

I USED TO RULE THE WORLD

SEAS WOULD RISE WHEN I GAVE THE WORD

NOW IN THE MORNING I SWEEP ALONE

SWEEP THE STREETS I USED TO OWN

I USED TO ROLL THE DICE

FEEL THE FEAR IN MY ENEMYS EYES

LISTEN AS THE CROWD WOULD SING:

"NOW THE OLD KING IS DEAD! LONG LIVE THE KING!"

ONE MINUTE I HELD THE KEY

NEXT THE WALLS WERE CLOSED ON ME

AND I DISCOVERED THAT MY CASTLES STAND

UPON PILLARS OF SALT AND PILLARS OF SAND

I HEAR JERUSALEM BELLS A RINGING

ROMAN CAVALRY CHOIRS ARE SINGING

BE MY MIRROR MY SWORD AND SHIELD

MY MISSIONARIES IN A FOREIGN FIELD

FOR SOME REASON I CANT EXPLAIN

ONCE YOU GO THERE WAS NEVER, NEVER AN HONEST WORD

THAT WAS WHEN I RULED THE WORLD

(OHHH)

IT WAS THE WICKED AND WILD WIND

BLEW DOWN THE DOORS TO LET ME IN

Letras4U.com » letras traducidas al español

SHATTERED WINDOWS AND THE SOUND OF DRUMS

PEOPLE COULDNT BELIEVE WHAT ID BECOME

REVOLUTIONARIES WAIT

FOR MY HEAD ON A SILVER PLATE

JUST A PUPPET ON A LONELY STRING

OH WHO WOULD EVER WANT TO BE KING?

I HEAR JERUSALEM BELLS A RINGING

ROMAN CAVALRY CHOIRS ARE SINGING

BE MY MIRROR MY SWORD AND SHIELD

MY MISSIONARIES IN A FOREIGN FIELD

FOR SOME REASON I CANT EXPLAIN

I KNOW SAINT PETER WILL CALL MY NAME

NEVER AN HONEST WORD

BUT THAT WAS WHEN I RULED THE WORLD

(OHHHHH OHHH OHHH)

I HEAR JERUSALEM BELLS A RINGING

ROMAN CAVALRY CHOIRS ARE SINGING

BE MY MIRROR MY SWORD AND SHIELD

MY MISSIONARIES IN A FOREIGN FIELD

FOR SOME REASON I CANT EXPLAIN

I KNOW SAINT PETER WILL CALL MY NAME

NEVER AN HONEST WORD

BUT THAT WAS WHEN I RULED THE WORLD

OOOOOH OOOOOH OOOOOH

Viva la Vida on Spanish

YO SOLÍA GOBERNAR EL MUNDO

LOS MARES SE ALZABAN CUANDO YO LO ORDENABA

AHORA EN LA MAÑANA YO BARRO SOLO

BARRO LAS CALLES QUE SOLÍA POSEER

YO SOLÍA TIRAR EL DADO

SENTIR EL MIEDO EN LOS OJOS DE MI ENEMIGO

ESCUCHABA COMO LA GENTE CANTABA:

"AHORA EL VIEJO REY ESTÁ MUERTO, ¡LARGA VIDA AL REY!"

UN MINUTO YO TENÍA LA LLAVE

AL SIGUIENTE LAS PAREDES SE CERRABAN EN MÍ

Y DESCUBRÍ QUE MIS CASTILLOS ESTABAN CONSTRUIDOS

SOBRE PILARES DE SAL Y PILARES DE ARENA

ESCUCHO LAS CAMPANAS DE JERUSALEN SONANDO

LOS COROS DEL CALVARIO ROMANO ESTÁN CANTANDO

SON MI ESPEJO, MI ESPADA Y MI ESCUDO

MIS MISIONEROS EN UN CAMPO EXTRANJERO

POR ALGUNA RAZON QUE NO PUEDO EXPLICAR

UNA VEZ QUE SABES QUE NUNCA HUBO UNA PALABRA HONESTA

ASÍ ERA CUANDO YO GOBERNABA EL MUNDO

FUE EL VIENTO LOCO Y SALVAJE

QUE TIRÓ LAS PUERTAS PARA DEJARME ENTRAR

VENTANAS ROTAS Y EL SONIDO DE TAMBORES

LA GENTE NO PODÍA CREER EN LO QUE ME CONVERTÍ

LOS REVOLUCIONARIOS ESPERAN

MI CABEZA EN CHAROLA DE PLATA

SOLO UNA MARIONETA EN UNA CUERDA SOLITARIA

OH ¿QUIEN PODRÍA QUERER SER REY?

ESCUCHO LAS CAMPANAS DE JERUSALEN SONANDO

LOS COROS DEL CALVARIO ROMANO ESTÁN CANTANDO

SON MI ESPEJO, MI ESPADA Y MI ESCUDO

MIS MISIONEROS EN UN CAMPO EXTRANJERO

POR ALGUNA RAZON QUE NO PUEDO EXPLICAR

YO SE QUE SAN PEDRO DIRÁ MI NOMBRE

NUNCA HUBO UNA PALABRA HONESTA

PERO ASÍ ERA CUANDO YO GOBERNABA EL MUNDO

ESCUCHO LAS CAMPANAS DE JERUSALEN SONANDO

LOS COROS DEL CALVARIO ROMANO ESTÁN CANTANDO

SON MI ESPEJO, MI ESPADA Y MI ESCUDO

MIS MISIONEROS EN UN CAMPO EXTRANJERO

POR ALGUNA RAZON QUE NO PUEDO EXPLICAR

YO SE QUE SAN PEDRO DIRÁ MI NOMBRE

NUNCA HUBO UNA PALABRA HONESTA

PERO ASÍ ERA CUANDO YO GOBERNABA EL MUNDO

This is a video of climate change, such as CO2 is a danger to the planet as it is violating the ozone layer and all thanks to services public domestic, since the industrial revolution brought electricity and other technologies by which our world isdeteriorating faster than in previous years so we need a miracle.

Therefore each of us we must do our part to heal the planet earth.

Whatever lyrics on Spanish

Soy libre para ser cualquier cosa que yo

Cualquier cosa que escoja

Y cantaré los blues si es que quiero

Soy libre para decir cualquier cosa que yo

Cualquier cosa que me guste

Si está bien o está mal, no importa

Siempre me parece

Que tú sólo ves lo que la gente quiere que veas

Cuánto más va a pasar?

Antes de que te subas al bus y no causes alboroto

Busca un apoyo en ti, no cuesta mucho

Eres libre para ser cualquier cosa que tú

Cualquier cosa que digas, si es algo bueno para mí, está bien

Eres libre para ser cualquier cosa que tú

Cualquier cosa que te guste, puedes patear la brisa si así lo quieres

Siempre me parece

Que tú sólo ves lo que la gente quiere que veas

Cuánto más va a pasar?

Antes de que te subas al bus y no causes alboroto

Busca un apoyo en ti, no cuesta mucho

Soy libre para ser cualquier cosa que yo

Cualquier cosa que escoja

Y cantaré los blues si es que quiero

Aquí en mi mente

Sabes que podrás hallar

Algo que tú

Pensaste que alguna vez conociste, pero ahora todo se ha ido

Y sabes que no es divertido

Si, sabes que todo se ha ido

Y sabes que no es divertido

Soy libre para ser cualquier cosa que yo

Cualquier cosa que escoja

Y cantaré los blues si es que quiero

Soy libre para ser cualquier cosa que yo

Cualquier cosa que escoja

Y cantaré los blues si es que quiero

Cualquier cosa que hagas

Cualquier cosa que digas, sí, yo sé que está bien

Cualquier cosa que hagas

Cualquier cosa que digas, sí, yo sé que está bien
