TOPIC 13 SCIENCE AND INDUSTRIAL ADVANCES
THE RAILWAY CHANGES TO THE WORLD
It is not easy, in the 21st century, when
cars, buses, and trucks allow us to
understand fast the gigantic effect that had
the introduction of the railway in the XIX.
Remember that, since the agricultural
revolution, land transport was the back of
animals like horses, mules, camels, or in
wagons pulled by those animals.
THE INVENTION OF THE RAILROAD
Rails, first of wood and then of Iron, had in some
mines of Europe for transport the mineral in small
carts, moved by Men or animals of draught, that
is why the first thing-steam-engine was For a coal
mine. It was made in 1814, George Stephenson
for a coal mine (it dragged 30 T to 7 km/h). His dilater improved. Ten years later, he inaugurated
the first railway line to transport coal from the
mine of coal.
THE STEAMBOATS
Until the beginning of the
nineteenth century, the
transport of larger quantities of
goods was by sea or river, in
sailing boats.
The application of the steam
machine to the navigation was
another important advance,
although, in the first
steamboats, the load of coal
needed to operate the machine occupied most of the space.
THE EXACT SCIENCES
During the nineteenth century, the practice of science produced great advances
in physics. Faraday (1791-1867), Ohm (1789-1854), and others studied
electricity and magnetism. These studies led Maxwell (1831-1879) to unify the
two phenomena in a single theory: electromagnetism.
