The Evolution Of Electrical Power

Few technologies have changed forever the way in which humanity does things. Some, such as radio, television or the Internet, have had a significant impact on how we communicate and for better or for worse have modified our behavior as a society. Others have served to drive great technological changes. But few technologies can be said to have been so fundamental as to mark a new era for humanity.

Although most of us were born too late to feel what was before and after the arrival of electric power in our lives, electricity has probably been the discovery that has most influenced a change in humanity and the world. Just think for a moment, after such a fundamental breakthrough, humankind has achieved an overwhelming advance in a few decades, which would not be anywhere near possible if we did not have electricity.

From the communications to the endless entertainment media that we currently have, thanks to electrical energy, that machinery works at the atomic level and allows us to enjoy pleasures like the music that I listen to when writing these words. But things were not always like that.

Evolution And History

Although the human understanding of electricity is relatively recent, we already knew of the existence of this rare and almost magical energy for several millennia. There are Egyptian records of nearly 5 thousand years old that speak of electric fish in the Nile river, and since then many other civilizations also described other similar marine animals.

It was the Greeks who gave the first tumbles with static electricity and electromagnetism, although as in most of their observations, the basis of their postulates was not misguided, many things were not entirely accurate.

There are those who believe that there are ancient civilizations that understood electricity much better than we think, is the case of births, which created pieces that could function as original batteries. In any case, it has not been proved that such objects were designed to be used as batteries, nor have other objects of that time that need electrical power been found, so this is a very controversial issue

Interestingly, discovering that electrical energy forms the rays seems to have taken us much longer. The first records that are held about it are of Arab civilizations of the fifteenth century, who used the word ray (raad) to refer to the phenomenon.
