I guarantee you that it was stowed
excuse me this evening I would like to
take you on a journey enough
an unusual trip to exactly
halfway between art and science
something that moves beyond the
boundaries of our planet earth that
explore the limits of our perceptions
and that has satellite protagonists
natural that is the moon and of the works
so small that they are invisible and
consequently works that lead to
limit of the concept of art itself
visual
I guess we start from the bottom of the
earth that each of you has been
at least once in life to visit
a museum
usually these are large spaces
full of objects that you can see with i
your eyes
typically paintings statues installations
of every kind there are museums of each
military quality museums agriculture
museums of science museums of archeology and
those who have more and so forth
and they are distributed almost everywhere where a
someone came to mind to open a
museum in a place where there is no one
place that has been explored almost 50
years ago by numerous crews of one
only nation and is called the moon what they are
let’s say the contours of this idea
everything starts from an American consortium
for the accuracy of the southern carolina
this consortium which is called last
robotics decides to join a project
international which is a prize
basically started by google the
giant mountain view this
competition assigns as first prize
$ 30 million for the first consortium
private that will place an object
on the moon a robot capable of accomplishing
a path of at least 500 meters and
send a transmission of
high resolution video and the goal
of this competition is that of
to develop
a new private entrepreneurship for
to open an era of development and of
exploitation of human resources and
basically the characteristics of a
museum that can be transported by a
object as a spaceship and placed
on the moon which must be
surely at least it must be
light because the cost estimates for
deposit a pound in the matter on the
moon
they speak of 1.2 million dollars then
these are astronomical figures here
sketches you see that the museum looks like
a bit of a can
therefore it has a volume lower than one
300 ml drink can and is
designed and made with materials that
they should be able to resist
for thousands of years in the conditions
of the lunar habitat from this rendering
3d that a museum split that yes
call monarch you see is a structure
very complex
without going into too much detail vi
just know that there are inside
numerous miniatures and works of art
in a sample of materials and objects
that come from the earth and that
symbolically they represent society
contemporary and lennon works that us
we have realized they are protected by two
of these ten screws you see
placed on the upper upper discs
of the central cylinder this is instead
the lander that is the object that deposits
the monarchs on the moon is
substantially similar to the lunar
excursion module that in Italian
we call lem that settled on the
moon with emissions of 69 and then in
avanti apollo is made of aluminum is
an object that at 4 and a half meters of
diameter and able to deposit on the
Lunar soil 270 kilos of useful material
therefore scientific experiments objects e
think that it burns well 1700 kg of
propellant to slow down and fall
make a soft landing as they say
this instead the robottino that is the
rover then an object that has the
ability to move at the speed of
18 centimeters per second maximum is
powered by photovoltaic panels
that generate
maximum electrical power of 100 watts and
then has a stereo room to take
let’s say some stereoscopic images in
high resolution
but how the idea of nano art was born
this was born in 2005 at that time a
Turin artist who is called
alessandro scali came to visit us at the
department of physics of the polytechnic
of Turin and showed us sketches on
a notebook and ask us you can
to realize these works in such a way
that are not visible to the human eye
it’s there for a while it seems like a challenge
absurd
obviously the answer was yes yes
let us start this path
together with him and realizing different
works and then we are always gone
arm arm to face different
challenges and we have also collected this
to be able to make works from
what the moon now specifies
that they were given to us were a lot
stringent we needed to do them
on large supports maximum mm x 1
and here you see the silicon support that
at this size above that piece of
silicon were made of incisions
nanometrics that are precisely the works
of fair art you see the artist’s hand
alessandro scali holding a door
samples with tiny pieces inside
silicon that are those on which
we did the champions and this is the
draft of the first work then the
drawing that makes the artist who is called
cam a which is a game of words camon and
moon and is an imprint that symbolizes
let’s say the access of terrestrial art
human on the moon and which also recalls
obviously the famous footsteps of the
astronauts selling limestone on the ground
lunar from the apollo and missions
obviously the first draft
realization that was made e
this is a lithograph what
it means to do a lithograph means
digitally transfer a geometry to
a rigid support in this case
silicon using something like a hammer
a chisel only that the tip of the
chisel is really very small in the
our case 76 ico meters that is we are
speaking of 76 billionths of mm and is
made not of steel like a chisel
but of gallium ions
which are the material we use
to climb another piece of information
interesting given by this white bar
here that is the indication of the
image size this bar is
a micron then a thousandth of
millimeter
this means that they but we have
fact is micrometric non-nanometric
so it was necessary to lear it
another interesting consideration that
what we are actually seeing this
sir the cciaa the intervention of this
morning of the other alexander
greyscale of chiaroscuro that we
we see it has nothing to do with
what we see with the light with i
our eyes because this is
an image made with a microscope
electronic and we see the properties
of matter from tichy to electrons
secondary so they are called who I am
placed in response to a brush
electronic, that is, a beam of electrons
primary that goes to plumb the
surface we had to do the smallest
and so we did it
if you look at the dimensional scale this
it is now 100 nanometers
and this that is sure is a groove you
see this groove is less than 50
nanometers wide
which means a few tens of atoms
placed one after another is really
small though if you have noticed
the work is much more simplified than
what you have seen before
because it’s here we clash with le
oddities of the quantum world ie the
uncertainty principle of
heisenberg who says it is
basically if I want to check
the force that I army with the hammer on the
chisel with high precision
small engraved because if you exercise one
force too high spa with silicon yes
it exerts too low a force it does not
scratch and then I do not do any
engraving for which I need to
check the force I lose control
on the position of the tip of the
chisel so I do not know where I am anymore
digging and I get an image that is a
little blurred then I have to simplify
the image because otherwise I do not have
plus the ability to make it clear
and therefore legible and visible
obviously not interview but with the
electronic microscope this is the
second work that was realized by
the artist’s draft is new
and is part of a series that the artist
called social ethics ie he coined
this neologism to describe the
contemporary society that is
characterized by a very high
technology content but from one
social regression of the
we did it then
micrometric torque keeping the same
geometry the material with which it was
fact is said but because it is said why
it is basically the ubiquitous material
more used cheaper more
known for everything related
smartphones and electronic devices
computers anything it has
of the electronics inside is based on the
silicon and we know it well and
we use this preferably fair
see the final work simplified
as before with respect to the previous e
nanometer like dimensions you see the
200 nanometer scale
this is the very complicated tool
which was used to accomplish
the works that is a microscope
electronic then a brush
electronic that allows us to see
what we do is a jonico beam
which is the chisel that allows us to
dig the surface of the silicon
the whole is then surrounded by a cage
of faraday or from a kind of
cobweb of copper wires that we need
to clean the work environment from
electromagnetic noise that will ever have
in our cities and ubiquitous
particular this tool was
placed inside a basement
of an unsuspected historic building
of the cross of Turin where there are the
work the laboratories of the center for
sustainable food technologists where
work of the Italian institute of
so we did it to
turin
this is my fellow cascia
she is the expert in lithographs and the
person who made the incisions
materially on the site and here we see
while he is opening the door of the
our imaginary spacecraft that then
be the tool with which we have
engraved in silicon equa on the screens
see the two works of art that are
been made
and the imprint of the artist Alessandro
climb almost to want to climb the moon
symbolically and with this concluded I
of course I want to thank you before
all
alessandro stopovers that unfortunately is not
He was present when he could come
but it is he we say the creator from the point
of artistic view of the Cascia project
that the person who dealt with doing
the denis and simone engravings that are
colleagues who cut silicon
professor shoots that was the
coordinator of the center where we have
tried the dix team for his
excellent organization of the event e
you for the attention thank you minutes
