Who descovered electricity?
Here is some information from http://www.electricityforum.com/electricity-history.html “900 BC – Magnus, a Greek shepherd, walks across a field of black stones which pull the iron nails out of his sandals and the iron tip from his shepherd’s staff (authenticity not guaranteed). This region becomes known as Magnesia. 600 BC – Thales of Miletos rubs amber (elektron in Greek) with cat fur and picks up bits of feathers. 1269 – Petrus Peregrinus of Picardy, Italy, discovers that natural spherical magnets (lodestones) align needles with lines of longitude pointing between two pole positions on the stone. 1600 – William Gilbert, court physician to Queen Elizabeth, discovers that the earth is a giant magnet just like one of the stones of Peregrinus, explaining how compasses work. He also discusses static electricity and invents an electric fluid which is liberated by rubbing. ca. 1620 – Niccolo Cabeo discovers that electricity can be repulsive as well as attractive. 1630 – Vincenzo Cascariolo,
1) “The history of electricity is a history of humans discovering and harnessing an essential force in nature: electromagnetism. Lightning is an awe-inspiring spectacle of electricity almost universally manifested across our planet, a common experience to nearly every human who has ever lived. Prehistoric depictions of lightning testify to its presence since the very beginning of human consciousness. Magnetism is not so obvious. The first evidence of human interaction with magnetic fields goes back about 2200 years. A precursor to the magnetic compass was utilized by Chinese fortune tellers as early as 200 BC.” Source and further information: http://www.codecheck.com/HistoryOfElectricity.html 2) “1. Ancient electrical, magnetic, and optical effects have been known since antiquity. – the ability of some materials, notably amber, when rubbed to attract bits of cloth or paper and the lodestone or natural magnet. 2. Early systematic investigation did not occur until the middle ages. Magnet
