About Mermaids


MERMAIDS

The word is a compound of mere, the Old English word for "sea", and maid, a woman. The male equivalent is a merman.

There are many Mermaids all over the world, the myth ( for some, the belief) can be found everywhere

Among the Neo-Taíno nations of the Caribbean the mermaid is called Aycayia. Her attributes relate to the goddess Jagua, and the hibiscus flower of the majagua tree Hibiscus tiliaceus. In the modern Caribbean the mermaid is found as Haitian Vodou Lwa La Sirene (literally, 'the mermaid') who is lwa of wealth and beauty and the orisha Yemaya. Examples from other cultures are the Mami Wata of West and Central Africa, the Jengu of Cameroon, the Merrow of Ireland and Scotland, the Rusalkas of Russia and Ukraine, the Iara from Brazil and the Greek Oceanids, Nereids, and Naiads. One freshwater mermaid-like creature from European folklore is Melusine, who is sometimes depicted with two fish tails, and other times with the lower body of a serpent. It is said in Japan that eating the flesh of a ningyo can grant unaging immortality. In some European legends mermaids are said to be unlucky.

Atargatis, The first Mermaid

The first known mermaid stories appeared in Assyria, ca. 1000 BC. The goddess Atargatis, mother of Assyrian queen Semiramis, loved a mortal shepherd and unintentionally killed him. Ashamed, she jumped into a lake to take the form of a fish, but the waters would not conceal her divine beauty. Thereafter, she took the form of a mermaid—human above the waist, fish below—though the earliest representations of Atargatis showed her as a fish with a human head and legs, similar to the Babylonian Ea. The Greeks recognized Atargatis under the name Derketo. Prior to 546 BC, the Milesian philosopher Anaximander proposed that mankind had sprung from an aquatic species of animal. He thought that humans, with their extended infancy, could not have survived otherwise. This idea reappeared as the aquatic ape hypothesis in the twentieth century.

Djullanar, The Arabic Mermaid

The One Thousand and One Nights includes several tales featuring "Sea People", such as Djullanar the Sea-girl. Unlike the depiction in other mythologies, these are anatomically identical to land-bound humans, differing only in their ability to breathe and live underwater. They can (and do) interbreed with land humans, the children of such unions sharing in the ability to live underwater.

Chinese Mermaids and the peal tears

In some ancient fairytales of China, mermaid is a special species whose tears can turn into priceless pearls. What's more, mermaids can also knit an extremely valuable material which is not only slight but also beautiful and translucent. Because of this, fishermen longed to catch them, but it's difficult for them to survive for mermaids' splendid singing can simply drag them to coma. Actually, mermaid is a symbol of wonderful creatures in Ancient China. They are deft,beautiful and versatile. And the fishermen who want to catch mermaids are a symbol of negative character.

Sirens

The sirens of Greek mythology are sometimes portrayed in later folklore as mermaid-like; in fact, some languages use the same word for both bird and fish creatures, such as the Maltese word 'sirena'. Other related types of mythical or legendary creatures are water fairies (e.g., various water nymphs) and selkies, animals that can transform themselves from seals to humans.[citation needed]

YEMANJA ( or Yemaja ), the MERMAID

In Brazilian mythology Yemaja is known as Yemanja, she is a beautiful mermaid goddess, who appears from the water surrounded by sweet melodies and carrying a comb and mirror made from oyster and snail shells. She will rise from the water seated on a sea shell wearing a crown of pearls and starfish. Her kingdom is the all the waters of the world.

In African mythology the supreme being created the earth, and created a pantheon of gods and goddesses known as Orishas, Yemaja was the Orisha who was responisble for all the waters of the world. She regulated night and day, the tides and rain. Yemaja was also said to have brought beauty to the world.

About Faraday and Empiric intelectuals...




OK, allow me introduce Sir. Michael Faraday...

Faraday's law of induction is a basic law of electromagnetism relating to the operating principles of transformers, inductors, and many types of electrical motors and generators. The law states that:
"The induced electromotive force (EMF) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit."
Or alternatively:
"The EMF generated is proportional to the rate of change of the magnetic flux."
In Faraday's first experimental demonstration of electromagnetic induction (August 1831), he wrapped two wires around opposite sides of an iron torus (an arrangement similar to a modern transformer). Based on his assessment of recently-discovered properties of electromagnets, he expected that when current started to flow in one wire, a sort of wave would travel through the ring and cause some electrical effect on the opposite side. He plugged one wire into a galvanometer, and watched it as he connected the other wire to a battery. Indeed, he saw a transient current (which he called a "wave of electricity") when he connected the wire to the battery, and another when he disconnected it. Within two months, Faraday had found several other manifestations of electromagnetic induction. For example, he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires, and he generated a steady (DC) current by rotating a copper disk near a bar magnet with a sliding electrical lead ("Faraday's disk").
Faraday explained electromagnetic induction using a concept he called lines of force. However, scientists at the time widely rejected his theoretical ideas, mainly because they were not formulated mathematically. An exception was Maxwell, who used Faraday's ideas as the basis of his quantitative electromagnetic theory. In Maxwell's papers, the time varying aspect of electromagnetic induction is expressed as a differential equation which Oliver Heaviside referred to as Faraday's law even though it is slightly different in form from the original version of Faraday's law, and doesn't cater for motionally induced EMF. Heaviside's version is the form recognized today in the group of equations known as Maxwell's equations.


I wonder...

Without Maxwell, The Faraday law would never be accepted... beacuse of LACKING OF SCIENTIFIC SUPPORT. the empirical scientist used to be a a ultrage for all intelectuals.

But...

Nowadays in a world where information just pop out toward our starving eyes, not always we consider to check out the sources or look into the real premisses of information, everybody believe in everthing as long there's no time to check out any information
There's junky food ( not simply fast food) and now "Junky information"( not simply fast information)

On the other hand, there are some people that despite of scientific formal skills can naturally surpass the straight science by the enforces of creativity, and can bring a new meaning for everything... it might be the power of syntesis and analogies, so needed to be understood by those who hardly can understand the scientific language, they just cut the crap and hit the ground running, toward to the point, straight into the bull's eye.

But... those new empirical scientists, teechers, visionaries, businessmen or even goodfellas must save all scientific knowledge possible due to have support for their theories... or we'll have the junky information again. The empirical intelectuals must have a great MAGNETIC personality, a MAGNETIC comunication skill ( or ability, or gift... ) because the new world is starving for the POWER of information to keep MOVING.

I said MAGNETIC and POWER

Yes... there's a relation between magnetic field and energy...

"The EMF generated is proportional to the rate of change of the magnetic flux"

Faraday was right... for sure.
