is born in woven a given over family to the commerce of, to
learn of the cantone and the mechanical talent, like indicated through
its visualized exact creation of a sundial fierce outside of the house
from its father, Associate of the Royal Society has carried it to the
Dr attention Henry Miles (, 1843). The John father persuaded
Miles to allow that John resides with he in Tooting, Surrey, until
1738, when John articled to Samuel Watkins, landladies of a school in
the quarter of Spital, London, which he
has successful like the master and owner of the school until its dead
women to 1772. The first contributions of Canton to science
were calculations arranged us of the times of the eclispes lunar,
publish in the "Ladies Diary between 1739 and 1740 to you". With Miles
it has been able to know the best students than
London which William
Watson and John Ellicott. It has acquired the
same reputation fastly, in great part for its invention of new method
of fabrication of magnets crafts them strong. It has maintained secret
of method, in the hope to make a sure yield from it, until the
publication of the treaty of To of the John Mitchell. of magnets crafts
them (1750). Its procedure has seemed much similar one to Mitchell,
than immediately the accusation of plagio. That has not prevented to
the real society of assegnargli the medal of Copley for 1751; The
cantone he has had a method before the publication of the Mitchell and
from that what is known of its character testifies its
innocence. In the 1752 Canton he has learned of the
French experiments that confirm the conjecture of the Franklin
approximately lightning bolt. Succeeding the experiments was the first
one in England in order to repeat with and in the process it has
independently uncovered that the clouds have come electrified are
positively (like suggested theory) that negatively. Its job on the
determination of the sign of loads with the cloud has lead Canton to
plan the very famous experiments on electrostatic induction that has
earned it a place in the electricity history. Moreover it has made the
discovery remarkable that the glass does not load always positively
from friction; the sign of the developed electricity depends on the
nature of the substance polished over it and the state of the surface
of the glass. Other contributions to the object were a portable
electroscope of marrow-sphere (1754), a method for electifying the air
from communication (1754), a careful customer of that stone bewildering
the tourmaline (a 1759) and improvement in the machine electrical
worker, covering the relative mercury amalgam shock-absorber and of
latta (1762). Like physical endowed amateur of its time, the cantone it
has visualized the interest in other subjects, like identifying the
cause of the water brightness of sea (organic matter putrefying); it
has invented phosphorus “of cantone phosphorescent strongly
made„ sulfur compound and of the covers calcined of the
oyster (CaS); it has maintained a newspaper meteorological; it has
recorded the every day variations of the compass; and demonstrated the
water compressibility, remarkable happening, that it depended on the
measures so as to from the minute that has been defied on its
revolutionary interpretation of they, even if is rises in feet the
accurate examination of a special committee of the real society and a
second medal of Copley in 1765 has earned it. It was a frequenter of
randello of the Whigs honest in the company of Franklin and the
ministers Dissenting like Joseph Priestley, of which history and the
present declares of electricity has had to a lot to its attendance
patient. The cantone it was one of the most distinguished of the group
of the men car-facts and self-educated that they were the better
representatives of English physics in the half of-eighteenth century. | |
