Medicine saw important advances in the 20th century, including the discovery of penicillin in 1928 and the structure of DNA in 1953, allowing for advances like cloning. Communication methods also improved, starting with the telephone in 1876 and advancing to transistors in the 1950s and microchips, making electronics smaller. Transportation was initially limited but saw major changes with cars starting in 1908 and aircraft from the 1903 Wright Flyer to the Moon landing in 1969. The internet, developed from 1950s computers, was created in 1991 and transformed how people access information but also enabled new risks. Overall, the author identifies medicine, communication technologies, automobiles, airplanes, and then the internet as the most important 20th century inventions.

2.  Medicine is the most important field from all times. In 1928,
Alexander Fleming discovered penicillin, which was a
important cure for many infections during that time. The DNA
was also an important discovery by Watson and Crick in 1953.
Because of this, now in 21st century, Scientifics can use DNA
for cloning and the Police can identify a criminal by just using
the DNA of this person and compare to their results. Also, the
discovery of the Polio vaccine was very helpful in the 1950’s
by Jonas Salk. In addition, surgery advancement is so helpful
for saving many lives of children, teenagers, adults, or older
ages.

3.  The ways we can communicate with our friends or families
changed during the 20th century. The telephone was one way
we can communicate easily, invented by Alexander Graham
Bell in 1876. This invention didn’t become popular until the
1910s and 1920s. A very significant invention was the
transistor in the 1950s. Since the transistor made possible to
have smaller and cheaper electronic goods to communicate.
The invention of the microchip was also an impact during
the 20th century because it allowed computers or phones to
become smaller, faster, and mobile. Without it, we might
still used those humongous cellphones people used way
back.

4.  During the 20th century, going somewhere
was a little bit difficult, because you didn’t
have too much options. To get to your
destination, you could ride a bike, horse-
drawn carriage, trains or walk. In 1908,
Henry Ford created the first Model T
automobile. Also, he is the founder of Ford
Motor Company which exist now days.

5.  The first manned flight was created by the
Wright brothers with their experiment of
aircraft in 1903. In 1969, was the first time a
manned spacecraft lands on the Moon by the
commander Neil A. Armstrong. Now in days,
airplanes and rockets are more advanced,
people can fly to another country by airplanes
with food aboard and a good comfortable seat.

6.  Another major advancement is the internet, which
many people now days are using it right now. The
internet development thanks for the electronic
computers in the 1950s. In 1991, the World Wide
Web was created by Tim Berners-Lee. Thanks for
him, we can find many jobs and useful things in
internet. In the other hand, if you don’t know how
to manage good the internet, it can also be
something dangerous. That is why the internet is
the last great inventions during the 20th century.

7.  For me I think that the first very important thing invented was the medicine. Because,
with the medicine, doctors now in days can help you with your sickness or prevent
you from getting sick. Also, surgeons can save people’s life in most cases. The second
thing I considered important is the way we can communicate now, through cellphones
or computers, which are the most easiest and faster way to communicate. Automobiles
are also an important invention to many people especially if they have work out of
town or somewhere far away. Another way to transport can be by airplanes, to travel
to another continent, country, or town. I put the internet at the final of the most
important invention, because it can be good and useful; but it also can be dangerous if
you don’t know how to use it very well. Like for example, hackers can be serious
thing; they steal your identity or robe you from your accounts.
