THE AUTHOR |
When Sir
Humphry Davy was at the end of his days, a friend, so, the story goes, asked
him which of his discoveries he thought the greatest. Davy, who was jealous
of his fame and professional reputation, considered for a while. Then he
named an electrical discovery, results of some of his chemical researches,
his, famous safety lamp, and ended by saving; "But the greatest of
all, my discoveries was the discovery of Michael Faraday". And Davy,
who died in 1829 did not know how truly he spoke. Michael Faraday was born at Newington Butts on September 22, 1791. His father, James Faraday, was a blacksmith who, had come to London from Yorkshire. He was very hard put to, to make ends meet, and young Michael experienced the hardships, of poverty throughout his childhood. |

About five years after Michael's birth, the family moved to Jacob's, Well Mews, Charles Street, Manchester Square. Here it ?was that Michael started his schooling, which consisted of little more than the rudiments of reading, writing, and arithmetic at a common day school. His hours out of school he spent at home or in the streets. When he had become famous, he often frequented this part of London and pointed out where he had looked after his, younger sister, or where he had played marbles in the street. But the young Michael was not allowed to run wild. His father had become a member of the Sandemanian Sect, and Faraday, as, his after life showed, became absorbed in deep religious convictions.
His trial year as
an errand boy proved so successful that in 1805 be was apprenticed to
Riebau, without premium, to learn the trade of bookbinder and stationer.
The next few years he was much occupied not only in learning his trade,
but, because he had access to books and his master allowed him considerable
leisure time in which to attend shilling lectures, in natural philosophy.
He made friends at these lectures and learned much from the books and
papers. He got very interested
in science and chemistry. Soon he was inspired with the ambition to give
up trade and adopt a scientific career. Then came the great
incident that was the turning point of his, whole life. While he was yet
an apprentice he had the good fortune to attend four of Sir Humphry Davy's
last lectures. Of these he made notes and then wrote them out in full,
with such drawings as he could introduce. He was so eager for scientific
occupation, even of the lowest type, that in his ignorance of the world
and simplicity of mind he wrote to Sir Joseph Banks, then President of
the Royal Society. Naturally "No, answer" was the reply left
by the porter. The notes he had made
with interest and delight he sent to Sir Humphry himself, asking him if
he could be allowed to drop trade, which be thought "vicious and
selfish", and to take up a scientific career. Davy replied courteously. One night when he
was undressing to go to bed there was a loud knock at the door. Davy's
carriage was below and his servant handed Faraday a note, as a result
of which Faraday went to the Royal Institution the next morning and was
employed as a laboratory assistant at twenty five shillings a week. At
once he became of invaluable help to Davy and they both experimented with
chloride. At this period they were both often injured by explosions of
chloride of nitrogen a dangerous gas. In the autumn of 1813
Sir Humphry Davy and his wife went abroad and Faraday accompanied them
partly as secretary and assistant, and partly as valet. Davy, who was
Faraday's lifelong friend, treated him with every consideration but Mrs.
Davy treated him as a menial and almost drove him to return. Michael Faraday kept
an account of his tour through France, Switzerland, Italy and the Tyrol.
The letters he wrote, during this time, to his mother and sister are typical
of the man. He returned in 1815
and was re-employed in the Royal Institution. From then on his life was
a time of steady intellectual growth, devoted to chemical research, the
explaining of chemical phenomena, and to the popularisation of science. His first research
experiments were along, the lines opened up, by Sir Humphry Davy. He experimented
with chlorine. One day Dr. Paris walked into the laboratory and seeing
an oily liquid in a tube censured the scientist for using dirty vessels.
The next day Dr. Paris received a letter.
Faraday had succeeded
in converting chlorine gas into a liquid by its own pressure. This led
to many similar experiments with other gases and produced like results.
Besides liquefying gases, he performed the first rough experiments on
the diffusion of gases. He discovered two new chlorides of carbon, investigated
alloys of steel, prepared several new types of optical glass, and announced
his discovery of benzol. Besides this, he helped much in the general improvement
of the laboratory. In 1823 he was elected
a Fellow of the Royal Society and two years later he became Director of
the lab?oratory of the Royal Institution. In 1833 he was made Fullerian
Professor of Chemistry, without the obligation of giving lectures. Now Michael Faraday
began the experiments that were to, bring fame and renown to, his name.
Basing his experiments on the work of Oversted and Wallaston in the realm
of electromagnetism, Faraday explained the continual rotation of a magnet
and the electrified wire round each other. This was in 1821. In 1831 he
made his great discovery of electrical induction. Thus he reached the
threshold of a career of discovery unparalleled in the history of pure
experimental science. In 1831 Faraday announced
his epoch?making discovery to the Royal Society. He showed that an electro-motive
force is set up, in a conducting wire when it is moved at right angles
to, a magnet field. If the wire is part of a whole circuit its motion
results in an "induced" current. To give in detail
all his experiments would take volumes, for so great and many were they,
and they resulted in thousands of others. He found that the various kinds
of electricity were all identical. Next, he turned to electro-chemistry
and. Electro-chemical decomposition. This he called electrolysis. Here
he introduced new names. Instead of "poles" for the terminals
that bring and take electricity he called them "electrodes".
The substance which is decomposed by the electric current he called an
electrolyte, and the constituents of the decomposed electrolyte he called
"ions". Electricity has, ceased
to be an intangible phenomenon - it has become a domestic and industrial
slave. Michael Faraday made this possible. His great discovery of induced
currents, which meant the production of electrical current from magnetic
force was the dawn of a new epoch. In 1841 Faraday had
a break down in health. His nerves were shaken, and his mind disturbed
Thus he went abroad with his wife a Miss Sarah Barnard whom he married
in 1821 for three years. During this time he did nothing, not even "reading
on science". He lived at the Royal
Institution for forty years, till in 1858 he was given a house on the
green at Hampton Court by the Queen through the instigation of Prince
Albert. Here he died in 1867, "just waiting". By his discoveries
he made the way clear for his, followers, to produce the dynamo - the
generator of electricity, indirectly we owe to him electric light and
power, the telephone, telegraphy, and a thousand other devices, found
by tapping the vast sources of electricity he discovered. He was a humble,
patient, brilliant scientist, whose achievements are among the highest,
ever attained by humanity, for the fruits of them may never be, exhausted. "The progress
of future research will tend, not to dim nor to, diminish, but to enhance
and glorify the labours of this mighty investigator". PETER TENNENT, |
