Now in the modern world there are many advanced technologies from telephones to televisions to refrigerators

And before, for example, in the USSR there was no such thing at all, even normal gas stoves were not there, now we can buy all this in a hardware store. For example, their phones were not there either before, only home phones were and phones at an early stage were huge and bulky. And the first phones the grandfather of our smartphone phones was made in the USA.
And he was very large, weighed about 3 kg and it was impossible to walk with him on the street, but it was a sensation for people of that time.they wrote about this in newspapers, magazines everywhere talked about him and even rumors about a new phone probably reached the USSR.
And this first phone was made by Motorola, which was then popular in 1973 by Martin Cooper. And after that they began to create phones that we see every day in people of the modern world.and in russia, a funny invention was the Kalash machine gun, which was created by a guy with the name Kalashnikov.the machine gun was made in 1947 and was issued to the armament of the soldiers of the USSR in 1949.
The plane in which we fly every day was not so huge that weighs more than 100 tons. It was first invented in 1903 and it was modernized over the years for tens of years so that it flew as it should and so familiar that we now fly every day.and in our time, everyone has a computer that they use every day, but in fact it was not originally like that.
The first computer was invented in the USA in 1942 by John Atanasov.
The first computer was quite large, heavy and weighed about 500 kg and his height was about 2 meters, or rather not the computer itself, but its processor.after many years of work by scientists, you see what these scientists did for us before half a century ago. So I think we should be happy and proud of those who created these technologies for us that we use every day and each technology has its own history and therefore we should appreciate it.
