After solving all the issues that prevented creation, the wheels were essential to allow the wagons moved and then facilitated agriculture and trade, moving goods from one point to another. other.
This was a discovery by Scottish scientist Alexander Fleming in 1928. It all started when he noticed a petri dish full of bacteria. After being contaminated with mold, the bacteria were found dead in all places where there was contamination.
This antibiotic mold resulted in the fungus Penicillium. Decades later, chemists developed the drug Penicillin.
The main developer of the light bulb was Thomas Edison who, through a generator, wiring and a filament bulb, created fully functional lighting.
However, this invention directly impacted people's sleep patterns. Before everyone went to bed as soon as it got dark, now we are awake most of the time and sleep only 7 to 8 hours of sleep.

When it was in 1989, the internet underwent a high evolution thanks to the invention of the World Wide Web by computer scientist Tim Berners-Lee. The major intention was to merge the evolving computer technologies.
The first arose in 1800 thanks to the physicist Alessandro Volta, when he wrapped stacked discs of copper and zinc in a cloth, submerged them in salt water and discovered that they conducted energy.
However, later there were more updates. And, finally, when it was in 1859, the French physicist Gaston Planté invented the first battery in which it is used until the present day.
It all started in 1783 with Joseph-Michael and Jacques-Ètienne Montgolfier, when they took to the skies in a hot air balloon. However, the first invention that actually worked came only in 1903 with Orville and Wilbur Wight.

This technology has been used for thousands of years, but in different ways. In cold climates, ice or very cold water was used to keep food at ideal temperatures.
