Il nostro futuro passa dalla scienza di base | Giovanni Porcellana | [Your TEDx Event Name]


[Music]
when I was invited to this
event called the place of science
I immediately thought of two things
first of all the physical place where it is done
science as a cern where I work but also
for sandolo as a citizen, not just like
scientist what is the role of science
in our society
when we talk about science there are two
basically basic science types
and science applied the science of
base part by pure curiosity
desire for discovery and knowledge
while applied science seeks to
try a practical use of
knowledge that we have developed then
it is quite natural to think of a place
for the science applied in ours
society
but what is the role that it can have
the basic science that at first glance
cern might seem almost useless
and a place of basic science and in
particular what is called
particle physics what
we do our goal and study
the fundamental components of the universe
and answer some of the questions
primordial of humanity where we come from
of what we are made what are the
laws that govern the universe and for
do that
we reproduce the moments during and
immediately after the big bang to try to
understand what happened in those very first
moments almost 14 billion years ago
as you can imagine it’s a job
extremely exciting in this place
of science tens of thousands of
scientists come from all over the world for
to be able to work together and give a try
give answers
we knock on the doors of knowledge and
we hope to open it, therefore, therefore
what is this role of science?
basis
first let’s talk about the technologies
at cern for our program
scientific
we have developed technologies
completely unique beginning with dal
lhc large hadron collider the largest
particle accelerator of the world a
27 kilometers long ring in
a tunnel one hundred meters deep
in the countryside outside of Geneva in here
protons tiny particles that
make up our atoms run almost
at the speed of light in two
directions until then collide and are
just these collisions connections
that we want to study thanks to
huge particle detectors
big tools like heavy buildings
thousands of tons that are skilled at
take the three-dimensional photos of the
collisions and try to understand what
It has been produced and must not only
be extremely precise but also
extremely fast because every second
tens of millions of collisions
they take place inside the detectors producing
a quantity of data that is equal to 200
thousand dvd in a second most
of these technologies did not exist
not even with we started to
work
and indeed our way of doing things
projects and in the long term dozens of
years and when we begin we establish already
what will be the technologies that there
they will be used for that kind of experiment
and we plan the research process e
development to initially get the
feasibility of these machines and then
industrialization because not
we just want to have us there
possibility of using them but also others
research centers
some of these technologies when
we started were just science fiction and
now they are the basic standard on which
the first industry works in this
sector
and clearly the impact is not just in the
physics but also in other fields
perhaps the most famous example is the world
wide web that was invented at cern
to put scientists in communication
from all over the world and now has
changed our life the ways we do not
we need them and you can not imagine
at the time but also medicine a
continues to have great influences from
part of particle physics
nowadays the many hospitals
particle accelerators produce
radioactive isotopes for medicine
nuclear or treat patients
suffering from cancer with radiotherapy e
the same technologies we use in
our experiments for detectors of
particles are used in diagnostics
for images to help medical oncologists
to diagnose a lot of illness
when they are developed in the laboratories
these technologies often have
difficulty getting out and going towards
the industry to go to society
if these connections are there often
they are spontaneous given by initiative
of scientists or staff with
connections what should be done
that we are trying and establishing gods
technology transfer processes
that continually put in touch
these two worlds the world of research
and the industry world so
maximize the positive impact on
company therefore clearly technology
creates a place for basic science
in our lives
instead what is the role of the discoveries
that we make discoveries like the boson of
higgs we think a moment about the theory
of einstein relativity
what maybe the waves come to mind
gravitational or perhaps the paradox of the
twins the same einstein did not have in
mind a practical application when
formula this theory
he wanted me
the races physical phenomena and yet a day
of today our systems of
localization as gps use
relativistic effects to give us the
our exact position more than one hundred
years after the einstein formulation
he is not studying a better candle than
we invented the light bulb is right
the meaning of progress and explore
roads new roads that never have
been discovered and this is one of the
true missions of basic science to
discoveries we make today will not have
maybe an immediate application in the
our lives
but they will become part of this
building that human knowledge is
maybe a tomorrow in 100 or more years
they can become a fundamental part
of our lives
but sincerely I think science
basic has however a place in the
our society even if the discoveries that
we do never have
a practical application even if it were
all knowledge in useful despite this
basic science will always be one of the
highest manifestations of curiosity
human of our insatiable thirst for
knowledge for this is fundamental
invest in basic research
why not invest in our being
human is an investment in ours
knowledge of our curiosity is a
invest in our being critical and
get informed in our know how to take
conscious decisions in our being
citizens because if you think about it for a moment
what makes a good scientist and a
good citizen are not so different
facts you were not to live like brutes but
to follow virtue and knowledge to aim
on basic research and an investment
long-term on our humanity e
on our future to say thanks
