TECHNICAL AND SCIENTIFIC ADVANCES
TECHNICIANS XVlll
1752
Lightning rods: the American scientist and statesman Benjamin Franklin placed them, in the form of cables, on the facades of buildings in Philadelphia, United States.
1757
Sextante: el capitán John Campbell lo construyó, aunque el primer instrumento preciso para medir la latitud lo ideó el inglés John Hadley, en 1731.
769
Steam Vehicle: Nicholas Joseph Cugnot, a French Army engineer, built what would become the forerunner of the automobile, a three-wheeled vehicle powered by steam, to tow a cannon. His speed was 5 kilometers per hour.
1768
Mechanical Thresher - The first practical thresher was invented by Scottish farmer Andrew Meikle.
1762
Sandwich: This tasty and popular form of food was a product of the game. John Montagu, Earl of Sandwich, a fan of games of chance, would not leave the table to eat and ask his cook to prepare some meat between two slices of buttered bread.
SCIENTISTS XVlll
Steam engine
In 1768, James Watt built the first model of a steam engine. It is an external combustion engine that transforms the energy of water vapor into mechanical or kinetic work. He had an important role in moving machines and apparatus.
The phone
Alexander Graham Bell is credited with the invention of the telephone in 1876. It was a device that transmitted sounds through a cable through electrical signals. It has been one of the most important inventions because it revolutionized the world of telecommunications.
The car
In 1885, Karl Benz developed the first internal combustion car that was shaped like a tricycle. It was equipped with a small horizontal single cylinder four-stroke engine and featured a carburetor and water cooling.
The plane
The Wright brothers in America invented the first airplane. The idea arose in 1899 on December 17, 1903 they flew for the first time
Light bulb
Although it has been attributed mainly to Thomas Alva Edison, in 1809 Humphry Davy in one of his experiments placed a thin strip of carbon between the two poles of a battery and created a fleeting arc of light, considered the essence of the operation of the light bulb.
The first bulb gave light for 14 successive hours. Edison later developed and refined it into the long-life bulb.

At the end of the 19th century, many discoveries related to heredity and genetics were made, including those of Gregor Johann Mendel (1822-1884), who established the principles that govern the inheritance of specific characters, including structure and color.
We have seen in the last posts of this blog how in the 19th century the Industrial Revolution was consolidated in England, it spread through various European countries, leaps to the United States and ends up contributing to what we call "industry" or "industrial sector" ends up being a fundamental component of the productive systems of all countries. The spectacular economic growth that certain countries have experienced in the 20th century has been largely due to the development and expansion of the industry, which has also led to an incredible creation of jobs of all kinds, in the industry itself, and in what we call “services”.
