He derived the word from the Greek for amber electra. It was known from ancient times that amber when rubbed could lift light materials. Gilbert added other examples such as sulphur and was describing what would later be known as 'static electricity' to distinguish it from the more noble magnetic force which he saw as part of a philosophy to destroy forever the prevailing Aristotlean view of matter.

De Magnete, magneticisique corporibus, et de magno magnete tellure. Browne calls the attractive force "Electricity, that is, a power to attract strawes or light bodies, and convert the needle freely placed". He is also the first to use the word 'computer' - referring to people who compute calendars.

London Otto Von Guericke builds the first static electricity generator. He had worked on his ideas in the s but had abandoned publication because of the persecution of other radical thinkers such as Galileo.

William Harvey had developed similar ideas but they were never published. De Homine Treatise of Man ; On removing the brain all movement stopped which would be in keeping with Descarte's theory but then, when the frog was dissected and a severed nerve end stimulated with a scalpel the muscles twitched.

This proved that movement of a muscle could occur without any connection to the brain and therefore the transmission of 'animal spirits' was not necessary. Swammerdam's ideas were not widely known and his work was not published until after his death.

However, he wrote many letters and his friend, Nicolaus Steno, did attack the Cartesian ideas in a lecture in Paris in Boerhaave published Swammerdam's 'Book of Nature' in the s which was translated into English in One experiment suspended the muscle on a brass hook inside a glass tube with a water droplet to detect movement and 'irritated' the nerve with a silver wire.

This produced movement of the muscle and it may have been due to the induction of a small electrical charge - although Swammerdam would have been unaware of this. In the diagram opposite - a glass tube, b muscle, c sliver wire, d brass wire, e drop of water, f investigator's hand. He demonstrates the transfer of static electrical charge to a cork ball across metres of wet hemp thread.

Later he found that the transfer could be achieved over greater distances by using brass wire. The jar is named the 'Leyden Jar' after the place of its discovery.

Ewald Georg von Kliest of Pomerania invented the same device independently. He showed that the properties of the shock were similar to those from a Leyden jar in that it could be conducted or insulated with appropriate materials.

The Torpedo fish and other species were widely known to deliver shocks and were often used in this way for therapeutic reasons. However, electrical theory at the time dictated that electricity would always flow through conductors and diffuse away from areas of high charge to low charge.

Since living tissues were known to be conductors it was impossible to imagine how an imbalance of charge could exist within an animal and therefore animals could not use electricity for nerve conduction - or to deliver shocks. Furthermore, 'water and electricity do not mix' so the idea of an 'electric fish' was generally not accepted.

An essay on the natural history of Guiana, London: The eel was out of water as it was not possible to produce the spark otherwise. He used thin strips of tin foil and demonstrated his technique to many colleagues and visitors at his house in London. Unfortunately he never published his eel experiment though he did win the Copley medal in and for his work.

The observations of Walsh, and Bancroft before him, added to the argument that some form of animal electricity existed. On the electric property of torpedo: Mr Sowdon and Mr Hawes, apothecary, report on the surprising effects of electricity in a case report of recovery from sudden death published in the annual report of the newly founded Humane Society now the Royal Humane Society.

The Society had developed from 'The Institution for Affording immediate relief to persons apparently dead from drowning'.

It was "instituted in the yearto protect the industrious from the fatal consequences of unforseen accidents; the young and inexperienced from being sacrificed to their recreations; and the unhappy victims of desponding melancholy and deliberate suicide; from the miserable consequences of self-destruction.

After the attending apothecary had declared that nothing could be done for the child Mr Squires, "with the consent of the parents very humanely tried the effects of electricity.

At least twenty minutes had elapsed before he could apply the shock, which he gave to various parts of the body without any apparent success; but at length, upon transmitting a few shocks through the thorax, he perceived a small pulsation: In about ten minutes she vomited:Cardiology (from Greek καρδίᾱ kardiā, "heart" and -λογία-logia, "study") is a branch of medicine dealing with disorders of the heart as well as parts of the circulatory timberdesignmag.com field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.
