use for carrying wagons since the sixteenth century, the history of 
modern train travel is just over 200 years old.The first full-scale 
working railway steam locomotive was built in the United Kingdom in 
1804 by Richard Trevithick, a British engineer. It used high-pressure 
steam to drive the engine. On 21 February 1804, the world's first steam-

powered railway journey took place when Trevithick's unnamed steam 
locomotive hauled a train along the tramway in Wales. However, 
Trevithick's locomotives were too heavy for the cast-iron plateway track 
then in use. The commercial appearance of train networks came in the 
1820s. In 1821, George Stephenson was appointed as an engineer for the 
construction of the Stockton and Darlington Railway in the northeast of 
England, which was opened as the first public steam-powered railway 
in 1825. In 1829, he built his famous steam engine,

of railways had begun. While flying machines had been dreamt up since 
Leonardo da Vinci's time, and likely long before, and thanks to the work 
of countless inventors over several centuries, the Wright Brothers 
became the first people to achieve controlled, powered flight. Beginning 
with their work on gliders, the duo's success laid the foundation for 
modern aeronautical engineering by demonstrating what was possible. 
Though fire is a natural phenomenon, its discovery as a useful tool 
marks a revolution in the pages of history. In fact, the controlled use of
