Inventions that revolutionized history
1. Internet
It is not known for sure the date or who was the person who created the internet, however the world wide web began in the 1960s. At first, the US military used the Internet as a way to transmit information between small networks, but the technology progressed rapidly.
2. Penicillin
Scottish-born scientist Alexander Fleming (1881-1955) discovered penicillin, the first antibiotic in history, in 1928. Since then, penicillin has become the main substance in the fight against various bacterial infections in humans.
3. Plane
This was the invention of the Brazilian Alberto Santos Dumont that revolutionized the world. Since the creation of the airplane, travel time has decreased considerably. Currently it is possible to travel to different states in a few hours or even minutes, quite different from what happened in the past.
4. Electricity
Did you know that before electricity was discovered, people ironed clothes with a hot iron? Also, did they bury the water to keep it cold? In addition, many of the food preservation techniques we know today were used in the old days because it was the only way to keep them fit for consumption.
Electricity was discovered from many studies carried out by the English physicist William Gilbert (1544-1603), a pioneer in conducting experiments that provided other scientists with ways to advance in their production.
5. Telephone
The telephone is considered one of the most visionary inventions of all time. Scottish scientist Alexander Graham Bell (1847-1922) registered the patent for the first electric model in March 1876.
Bell was also responsible for mass producing the phones. Thus, in 1886, these objects were already present in about 150,000 homes in the United States. However, since then, many changes have occurred and today we have extremely advanced versions of these devices.
6. Printer
Finally, we have the mechanical printer. The first was made between 1440 and 1450 by the German Johannes Gutenberg (1396-1468). Furthermore, after its creation, the equipment became popular very quickly and was essential to expand access to works such as the Bible and also the theses of Martin Luther.
