 The Internet first began in the 1950s in USA during the Cold War between the US and the Soviet Union. Computer that were used by the government were 4 metres long and weighed almost a ton which made them very unreliable because they were expensive and in limited quantaties. After some time they started to develop a network which was supposed to give access to computers that were located far away from a person that wanted to use them. Many different scientists were put on this project so the Internet has no true inventor. In 1965 Lawrence Roberts used two different computers to make them "talk to each other" and later the first messages through the internet were sent. The first generation of the internet was born called the Arpanet, but it was decomissioned in 1990 and was replaced by a newer one. Many alterations to the internet led to the internet we know today. It's used to almost everything across the globe: shopping, schoolwork, business meetings and countless other ...

 In the late 1960s Marion Franklin Rudy created a prototype of an air bag that was supposed to be put on in the heel of a shoe, in 1978 this invention was called Nike Air. Since then many people started to try to make footwear more comfortable or innovative. In 2010 a basketball shoe made by a brand called APL featured a spring underneath the ball of the foot which increased the vertical leap of a player by almost 9cm, because of that they were banned by the NBA very quickly. In 2011 Nike released a replica of the shoes shown in "Back to the Future" - the Nike Air Mag. Their laces were swapped with a self lacing mechanism just like in the movie. They were limited to 150 pairs and nowadays can sell for as much as 10 thosand dollars. In 2019 there was a controversy about another shoe made by Nike - the Nike Vaporfly. It was a running shoe that had specially made foam for the lower part of the shoe and had three carbon fiber plates in it to make it more springy. By wearing them ...

 Drones have been around since 1917, when Peter Cooper and Elmer A. Sperry invented the first automatic gyroscopic stabilizer, which straightens and levels out aircraft during flight. Their technology was used to create unmanned planes, but they were never used. Since then this concept has spread out around the world and many different types of drones have been made. Military drones also called UAV's (unmanned aerial vehicle) are now widely used to perform missions such as looking for someone or attacking enemies. They are typically shaped like a plane but all the windows are usually missing and have extra elements like cameras or sensors. The second type of drones are very different and are not used by the military, they're the ones that we might sometimes see flying above our heads. They typically have a couple rotors which give them the ability to fly and hover in the air. These drones are used for many things like taking photos, videos or in the future deliver packages to u...

  Electric cars are vehicles that use onboard rechargeable batteries instead of fuel to provide propulsion for the wheels. The first electric car was invented by  Gustave Pierre Trouvé in 1881 and the first "real" electric car was designed by Andreas Flocken in 1888. The first modern electric vehicles were created by California Air Resources Board in the early 1990s but they went off the market very quickly. Nowadays electric cars are becoming more and more popular because they are advertised to be more environmentally friendly and cost less to operate. They emit no CO2 and are more efficent than regular cars.  A lot of companies like Ford,Volvo and Jaguar are planning to produce only electric vehicles by 2030. But is it a good thing that this is happening? Electric cars are still a lot more expensive to buy than normal cars, they use rare metals for their batteries and the driving distance is usually shorter. These downsides are a very big problem for this concept but ev...
