Introduction The twentieth century was one of the most remarkable centuries in history referring to the technology advances and scientific discoveries that it had. They are still continuing today. The advances that I believe shape our world today that occurred in the twentieth century are internet, radio and antibiotics. Like I mentioned before, there were so many advances; even inventions. Yet I feel that these three are extremely important.
Radio
The impact that the radio had on the twentieth century is not appreciated. Not only did the radio make it possible for a person to be heard thousands miles away without any use of wire. During the end of World War 2 and into the 1950’s the radio was the center of family life. The radio was the source of entertainment and news. The only time the radio lost its fame was when the television was invented, and when families were replacing the radio with a television. Sadly today the radio is mainly used in vehicles. The radio is a great tool for drivers to keep from falling asleep behind the wheel or some radios in new models of cars; they can communicate through their radio speakers.
The advances that the radio had during the twentieth century been very important and life changing. When the radio was first invented it was a great success and it did the job it entailed. During the 20th Century the radio made some very important advances, they are advances ranging from transmute radio signals to amplifier levels, and FM radio to HD radio. All these advances made the radio what it is today. Transmatic radio signals are when a wireless receiver can transmit sound from over 2000 miles; this is a new way to send Morse code. FM Radio and HD radio advances came in the late twentieth century yet they were just as important; the FM radio came to solve the static problem that the AM radio was having. Rather than increasing the strength of the radio waves, Armstrong changed the frequency on which the waves were transmitted. HD radio came to bring a clearer sound and by doing so the Federal Communications commission sets a testing schedule for all radios to have HD, never just an option.
Antibiotics
It is bazaar to imagine a world before the development of antibiotics. Penicillin was invented just 86 years ago. During the twentieth century antibiotics had some great achievements. Antibiotics serve an important role of keeping the public healthy. During the 20th century antibiotics advanced mainly because the invention of Penicillin. Antibacterials are designed to test bacterial infections. Billions of bacteria live under our skin; antibiotics are preventing the spread of the bacteria by killing it. 90% of children with bacterial meningitis died before antibiotics. The children that lived had severe lasting disabilities. The invention of Penicillin decreased the number of deaths due to bacteria illness.
Internet
In the twentieth century the internet was not what it is today. The internet is connecting a computer to any other computer in the world via dedicated routers and servers to get us information we need. When more than two computers are connected over the internet they can send and receive information, graphics, games and so much more. The internet is not owned by anyone, there are several organizations around the world that collaborate in the development and functioning but it is not owned by one person. The high speed fiber optic cables are owned by the telephone companies in the respected country. When the internet first began in 1960, it was for collaboration in military research for business and government laboratories; today everyone has access to it and can search anything they desire.
Conclusion
To conclude the twentieth century was extremely important due to technology advances. Today in the twenty first century, we would not be where we are without the advances we had a century ago. We are living in a world that is ever changing and we need to run with it and accept it.
