PENICILLIN
(David García)
In my opinion
the Penicillin is the best invent of the world, because this help people
all time. Penicillin was discovered by Alexander Fleming. This was the first
antibiotic used in medicine. The person who discover the penicillin told
the story of his discovery. Penicillin was discovered by Alexander
Fleming. The exact date was September
15, 1928. He was studying bacterial cultures. He was studying Staphylococo but accidentally
forgot a sample near the window. Fortunately, he didn´t throw the
sample.
The window where
was the sample, was open. In this one there was humidity but also something had
killed the bacteria. What he called Penicillin fungus; it was capable of
killing deadly bacteria. Fleming won the Nobel Prize with other
scientists for the discovery of penicillin. Penicillin is a medicinestar.
INTERNET
(Santiago Salazar)
In my opinion
the best invent of the world is the internet, because when
you need to see a friend who life in another country you can do a
video meeting in different platform, and now we are an important fact in our
lives, when the internet comes change the rules, now we do not need to
waste time searching for countless of books, now the books are virtual.
Then with the
passage of time we have been able to watch videos, listen to music and even get
to see a television program, but it also became a weapon, since they can steal
your personal data, your bank accounts and steal your money without the
need for an cash machine.

THE
CELLPHONE (Nataly Bautista)
I think the
most important invention is the cellphone Communication has been a great
tool for friendship and also for business and for that reason there was
several inventors who wanted to do communication more effectively
some of them did a great job and there was also many of whom later filed
intellectual property lawsuits when telephone use exploded), Alexander Graham
Bell was the first to be awarded a patent for the electric telephone in
1876. He drew his inspiration from teaching the deaf and also visits to his
hearing-impaired mom. He called the first telephone an
