2. Over the years, between 1700 and 1848, there
were several very important inventions,
which helped us to grow as human beings .These
discoveries were made by people who step into
history as very important people.
3. The invention of the modern piano is credited to
Bartolomeo Cristofori, then owned by the Republic
of Venice (Italy), who was hired by Prince
Ferdinando II de 'Medici as conservative
instruments. He was an expert harpsichord maker
and that's how he could become familiar with the
techniques of making stringed instruments
keyboard. Not known precisely the date on which
Cristofori workshop in Florence came the first
piano, but an inventory made by its patron, the
Medici family, the existence of a piano in the year
1709 is indicated.
4. A mercury thermometer is a type of thermometer that is generally
used to measure the temperatures of the selected material. The
physicist Daniel Gabriel Fahrenheit thermometers worked at first
with alcohol, but in 1714 made the key breakthrough by using
mercury. The Fahrenheit thermometer was first able to determine
the thermal level with sufficient accuracy to be useful to scientists.
5. Its name comes from the arc 60, a sixth of
a full circle of 360 degrees. It is a
mechanical-optical instrument that has
served for almost 3 centuries to place the
great explorers of our contemporary world.
And still it used when electronic
navigational aids do not work for some
reason. It´s created by John Campball.
6. The spinning jenny is attributed to James Hargreaves. He was born in
Oswaldtwistle, near Blackburn, around 1764.
At the time, cotton production could not keep up with demand, and
Hargreaves spent some time considering how to improve the
process. The flying shuttle had increased yarn demand by the
weavers by doubling their productivity,and now the spinning jenny
could supply that demand by increasing the spinners' productivity
even more.
7. In 1767, Joseph Priestley discovered a method of infusing water with
carbon dioxide when he suspended a bowl of water above a beer vat at
a local brewery in Leeds, England. Priestley found water thus treated
had a pleasant taste, and he offered it to friends as a cool, refreshing
drink.
8. Winzer went to Britain before
1799 and became interested in
technology and fuel economy. In
1802 he moved to Paris to
investigate the "heat-lamp" that
the French engineer Philippe
Lebon had patented in 1799.
Returning to Britain, he opened a
factory of gas and lit in 1807
one side of Pall Mall London by
gas lamps. Between 1804 and
1809 he requested some
privileges to Parliament for
company Gas Light and Coke
Company, being denied. Winsor
returned to Paris, but the
company failed to make much
headway so closed in 1819.
9. A steam locomotive is a railway locomotive that produces its pulling power
through a steam engine. These locomotives are fueled by burning
combustible material usually coal, wood, or oil to produce steam in a boiler.
The creation of steam locomotives began with the development of the
steam engine. The invention of the steam engine dates back into the late
17th century. In 1698, Thomas Savery, an English inventor, patented a
device that allowed for the use of steam to pump water.

11. During 1831 and 1832, Michael
Faraday discovered that an
electrical conductor moving
perpendicular to a magnetic
field generated a potential
difference. Taking advantage
of this, he built the first
electromagnetic generator,
the disc Faraday a homopolar
generator, using a copper disc
rotating between the ends of a
horseshoe-shaped magnet,
generating a small current. It
was also used as a power
generator on a bicycle to
produce light of low intensity.
12. Batteries come in many shapes and sizes, from miniature cells used in hearing aids and
wristwatches to battery banks the size of the rooms that provide standby power for telephone
and computer central data center. the March 20, 1800, Alessandro Volta announced his
invention of the stack, which now bears his name, the Royal Society.en 1836 John Frederic
Daniell invented the Daniell cell, from the pile of Volta, which prevents the accumulation of
hydrogen. Soon after, when already evolved and increased power by William Robert Grove
who invents the eponymous stack it was widely used in telegraph networks United States until
1860.
13. Peter Durand was a British merchant who is widely credited with receiving the first
patent for the idea of preserving food using tin cans. The patent was granted on August
25, 1810 by King George III of England.
Durand's patent was dedicated to the preservation technique rather than to the vessel.
The technique itself was developed previously by a Frenchman, Nicolas Appert. However,
Appert used exclusively glass vessels whereas Durand was the first to mention in a patent
use of tin cans.
