Il lato umano dei satelliti | Fabrizio Villa | TEDxNovara


you would be interpreting this picture

taken only from a software algorithm

answer this question I ask you to

close your eyes and imagine

be in your city

imagine the deafening traffic

during rush hour

imagine doors that open and yes

they close trucks that unload and load

goods also imagine the sound of

roberta horn that has two twins and

was blocked by a car in

second row

imagine a pneumatic hammer

love in progress children who run e

imagine even the sound of one away

turtle of a turtle’s paws

that walks slowly inexorably

following his path

open your eyes if you have closed them

and if you have imagined the noise

citizen so you will surely also

imagined the turtle is

insignificant noise of the steps of the

insignificant turtle compared to

citizen noise but if the turtle

he impressed in his carapace in his

shell the map of the universe

of the universe in which we live and

of the universe in which we were born then

that turtle becomes the most thing

important that there is reality is a bit

different imagine to replace them

your ears with parables

satellite those to see the

television

and imagine that it’s all the noise

citizen is the noise of smog

electromagnetic cell phones

microwave ovens wireless televisions

digital terrestrial anything that

puts an electromagnetic field and is

unbelievable

and we do not realize that beyond

this noise we are hit by one

electromagnetic radiation it has had

origin at the time of the big bang 14

billions of years ago

I like to think but that’s how

leave the theater

come here invested by this

radiation called radiation

fossil or background radiation a

microwave that originated 380,000

years after the big bang and that is

its intensity is practically constant

it does not vary

in reality it is not really that way

if I look at it from one direction

rather than another

there are slight differences of

intensity and these slight differences

they are so small as to be one

part of 100,000

rather I will say more in polarization

this radiation

assuming to look at her like with

Polaroid glasses of this radiation a

of the small differences of a part on

one million and how to measure these

differences and how to measure the waves of the

sea ​​from a deep from the depth

from the bottom of the ocean but one

depth of 100 km 10 times more

from the Marianne pits

this radiation was measured e

mapped and you see here those lisse that

you see it is nothing but ours

celestial sphere in which we are immersed and

those points every point of that map is

a different direction in which

we observe and those differences of

intensity are those different colors that

we see

and if we enlarge this map

discover something that you already know the

difference of one point to another the

color the size of these points la

direction of these lines you see there

they say how the universe is made that

the universe was indeed old 14

billions of years ago or rather 13,700 99

billions of years ago

and note the three decimal places like the

price of gasoline tells us so many things

tells us that they lit up at first

stars after 700 million years tells us

also that the universe has suffered one

incredible an incredible period of

expansion at the beginning and expands

even now and it’s accelerating

this expression also tells us that

map that much of the universe

we do not know him because we succeed

only to see 5 percent and we know

that 5 percent of the universe is

composed of ordinary matter such as the

our like our body ours

atoms that 26 percent are composed of

dark matter and we do not know what it is and

even 69 percent

of the universe is composed of energy

dark is as if we had a jar of

jam and with a teaspoon

we could only eat 5 for

one hundred

knowing well knowing that everything else

95 percent of the contents of the

jar and the most good part more

tasty but still not able to

eat what I told you

until now it goes under the model name

standard of the universe we know that

there was the big bang he had

this fossil radiation originates

it is expanded and the universe is

cooled until today

galaxies are formed to the stars

so far until the moment when the

let’s observe and I was lucky enough to

work for 15 years on the satellite it has

made that photograph of the universe

satellite is called planck and has been

launched by the European space agency

May 14th , 2009

and has been placed in an orbit

around a million and a half of the sun

kilometers from our land far beyond

beyond the lunar orbit it is all about

2 million turns on itself for

to map the whole time in four years

celestial within the satellite there

they were two Italian instruments and

a French and these tools have

observed the universe at different frequencies

different colors and this way of

watching different colors allowed us

to separate the big bang signal from

everything else from the signal from the

galaxy the signal of the steps of the

turtle noise of the steps of the

turtle from the urban noise and

see here the image of ours

galaxy as it was obtained from

satellite planck that has been discarded

to observe the big bang

but these data were used to study

our galaxy in a detail

incredibly sophisticated and as has

said one of my expert analysis colleagues

data planck data

satellite planck are like pig not

nothing is thrown away

when I started working for planck

on the one hand we had the chance to propose

new things there was little or nothing

there was an idea, a rough draft and

propose we had the chance just for

propose new ideas and new techniques of

building and on the other the

extreme awareness of doing things

with a penalty so you can launch

a 700 million euro satellite

in space without any failure

blanc was a satellite

technologically incredible gave the

away to the construction of satellites that yes

they are developing now according to one

architecture studied here every single one

piece of special planck is shown

only two

this for example are two long tubes

meters of length that carry the

signal from a temperature of about minus

250 degrees at a temperature of about a

room temperature and with want the

signal of the band and inside for

then be sent to the ground because above

there are three there have been three

such incredible fridges

they even allowed to

cool some parts of the satellite

up to the temperature of minus 270 degrees

even less than 273 degrees centigrade

Celsius

is another piece of planck here

see that this was like this

luca measured the laboratory at

thermal characteristics of the whole

universe in here in this piece

there is even an entire universe that

it served us to do to use it like

reference for our comments

I have learned many things workability

I also learned that in science where

everything is coded and where the technology is

the contribution is taken to the extreme

human made of ideas bets

experience is essential and must

remain fundamental

I also learned that the great discoveries

the great experiments in the large ones

bets where the big term can

be applied to anything that

we do are possible because when

we’re doing it we have that

perception of doing something

impossible as for example francesco

who decided to look at one by one

quality data of the satellite planck in

flight because it was absolutely not

convinced that automated software

they could control them well and had

reason

or as a maura watching with the satellite

of the planet Jupiter has discovered how it was

made the telescope as there was

modified the telescope to a million e

half of kilometers from us or how

gianluca that with the chillers of

planck is one of the three studied ha

invented the way to always regenerate it

a million and a half kilometers in the way

that the observations rather than last 18

months lasted four years plank

provided a lot of maps each

we have elaborated with algorithms

sophisticated with the most powerful computers

that between the various maps each with a

different taranto in different

analysis parameters of the many ones

maps if they have been chosen if they are

choice one to represent ours

universe our one-level model

but we are sure to have chosen the map

right and I like to compare planck ha

a big camera that there

allows you to take pictures on one level

of incredible crazy detail then

we take these photographs we give them in

gorini meal for example of

face recognition for example

automatic algorithms that ce

classify according to color

predominant based on the objects that there

I’m inside the photo o

they are even developing

algorithms to decide whether a photo and

beautiful or not according to the canons

aesthetic standards of photography

this thing could put us to

sure we are we feel safe

facing the arrival of these technologies

but we are really really right

convinced to go towards this

direction

or we still prefer to choose the

face with a particular expression e

we still like to choose photography

which is beautiful for us

comparing blanc to our life of

everyday

I am asked to ask if the advancing of the

technologies and indiscriminate use

of modern technologies we can

tarnish the human privilege

typically human to be artists

of our life

in short, I will repeat the question you would do

analyze this map only at one

software algorithm thanks

[Applause]
