1. THE MASS OF THE EARTH
Noemi Alfaro, Jorge Andreu, Daniel Aparici and Maria-Andreea Banu tried to present the
work of the scientists who devoted his life to researching about this phenomenon of the
mass of the earth. First began his presentation by introducing the topic by explaining that it
is the land mass and the various scientists who studied this issue: Isaac Newton, Albert
Einstein and Peter Higgs.
They began the actual work of Isaac Newton talking about his laws. In this way the mass
of the Earth is m = 5.95·1024
kg.
Then they talked about Albert Einstein emphasizing his theory of relativity. From this point
of view the mass depends on the speed, and the energy is E=m·c2
.
They also explained Peter Higgs has obtained the Nobel Prize of Physics in 2014 because
of the Higgs boson, that is the quantum of mass with aproximately 126 GeV/c2
. So the
mass ot the Earth contains aproximately 8.85·1040
times the mass of the Higgs boson.
They explained it well, because we understood them. And this topic is very interesting. It's
important that thanks to technological advances everyone can learn more and have
knowledge of this, and don't confuse assumptions with facts.
