The Internet

Years ago, before the Internet exist, people find the information in encyclopedias and not in Wikipedia. When the whatsapp didnt exist, toy talk more by phone. People make invitations by paper, but nowadays they send us, from whatsapp.

AIRPLANE

The concept of the airplane has only been around for two centuries. Before that time, people tried to navigate the air by imitating the birds. They built wings to strap onto their arm or machines with flapping wings. It seemed like a good plan, but the trouble was that it worked better at bird-scale than it did at the much larger scale needed to lift both a man and a machine off the ground. In 1783, some aeronauts made flights in lighter-than-air ballons, filled with hot air or hydrogen gas. But this wasn´t either a practical way to fly. In the 19th century, an English baronet conceived a flying machine with fixed wings, a propulsion system, and movable control surfaces. This was the beginning concept of the airplane that changed lifes of people all over the world.

The light bulb

In any normal room of your house you can find a light bulb which lights up the room. People have been lighting up their rooms for many years, but the light bulb was not invented until 1879.

Before there were light bulbs, eventually people used candles or natural light to light up their rooms. This was a problem because candles did not light up enough and because during the night it was dark. In the 19th century, James Bowman Lindsay invented the light bulb. Later in the 60s, the first red luminescent diode was created by Nick Holoyank. This made the light bulb last for a longer time and waste less energy. Scientists continued developing the light bulb because of  those two reasons. Finally, in 2010 LEDs of colours were introduced in the market. Some of the advantages this light bulbs had is that they were not toxic, because they did not contain mercury, in addition to its efficiency.

At last, people could work at night and see during it.
