Transcript of 05.04 Modern Science: Assessment
Medicine is the most important because it helps save lives. Automobiles help you to get where you need to go quickly. Cell phones help you to communicate when you are not at home. Televisions help you to keep up with the news and information going on around the world.
The discovery of penicillin is attributed to the scientist Alexander Fleming in 1928. If this medicine had not been discovered, many people could have died from preventable diseases.
Automobiles have become more advanced over the years but they still have the same benefits. They make transportation much easier than walking, help you get to your destination faster, and to more places in one day.
The development of mobile telephones began in 1918. However, the first cell phone was created in 1973 by a Motorola employee. It sold for over $3,000 and was nicknamed the "brick" because it was so big. Over the years cell phones have become inexpensive and much smaller.
The televison was officially invented by Philo Farnsworth in 1927. It was not developed into the television that was marketed until the late 1940's. When it came out the picture was black and white and now we have color. The styles have changed over the years and there are now even portable televisions.
