Et si faire le vide, c’était aussi faire le plein ? | Etienne Klein | TEDxParis


[Applause]

you all know what it means to do

full it must be said that it’s easy

just go to the pump at the

condition obviously that the pump where

we will not be a vacuum pump

but to refuel instead

empty what does that mean is this

that it’s the opposite of refueling

ie rubles and until

the tank gauge indicates that the

tank is empty we guess what to do

the emptiness is still a little more

complicated it’s a little more useful than

simply broke down

so first what is the empty

a quick look in a

dictionary puzzles because he

shows that there are many kinds of

empty

for example the vacuum that can be done

with a vacuum pump does not have big

thing to do with Hindu nothingness

neither with Buddhist emptiness nor with

the void that I could do around

I have the right cigar in a room

nor with the vertiginous emptiness that is

frail acrophobes and who exit

the mountaineer and therefore by an ironic effect

which could be that the move it be

victim of too much of

meanings and so it must be specified

what is meant by this word has proceeded

to what paul valery call a

cleaning the verbal situation the joy

that I forgot the quotation marks of which I

again it is necessary to proceed

I wanted to quote a cleaning of the

verbal situation I closed guillet for

speak like paul valery like that one

is quiet

the idea of living she evokes first

the absence of anything the nothing

nil that are three words almost

synonym that is to say they say to

pretty much the same thing this idea of

empty

about that you noticed a

amazing thing sexy have said these three

words one behind the other in the

preceded by the pronoun game that

give this I have nothing vacuum I did not

want nothing then 7

this weirdness of us is hardly

even she misleads us because doing

the void is not the same as

first want nothing because to do

the void must already want to do

emptiness it is not doing the

nothingness

that is to say shaved the universe you

to stay modest this is not either

to do nothing is not to be lazy

and so even if the idea of empty evokes

a rarefied presence

the absence the emptiness it’s not the same

thing that nothingness and that’s so much better

for me who talks to you about it because

the idea of ​​nothing if we think about it

little is an unthinkable idea unthinkable

because in fact it’s an idea that is

destructive of itself

as soon as we start to imagine or

think nothingness we do some

thing that precisely he can not

be as soon as the idea of birth

forge in our mind the movement

even of our thinking transforms the

nil in question a kind of

substance to which we are going to attribute

a spatiality a materiality that the

nose we could not own without

contradict his own definition is

so a paradox think the nothing is

never thought of anything the idea given in

is a matter to think that if we are

do not think since it becomes a kind

of material that destroys the same

data years it is as soon as there is

thought

so if loving is not nothingness

what’s another one of the definitions by

quick example that’s what’s left in a

container after we have it all

removed so the alive it would be the place of

the radical gap of emptiness

absolute except that this definition poses

a problem because if the vacuum is

nothing is that he has something

something special and

curiously this something of

particular must not be must not

be removed when empty

otherwise the void in question becomes a pure

nothing that can not be since we have

said he was something so

so to make the void

it is absolutely necessary to remove everything

absolutely everything except emptiness

it’s been three minutes since I

spoken

and we did not go much further

in circles I even feel like

a pitcher to look like a pitcher

even what is a pretty feeling

unpleasant but that I can

interrupt by reminding me that the

jug

it is precisely the chosen example of

cards to talk about emptiness if I take

a jug I can remove the water she

contains then it contains air

keep a jug

the jug era I can pump it to

that moment he stays in the jug the

electromagnetic radiation emitted

by these walls game can cancel it in

bringing the temperature of the pitcher to

absolute zero

we quote I can remove the jug it goes

stay a place a portion of the spaces

should I also withdraw

the space where should I interrupt

the exfiltration company that I come

to begin

where stops the list of objects that I

have to tea to empty

ask this question is to understand

that all in the phrase emptiness it’s

what’s left when we’ve removed everything

depends on the physical theory that I

chosen as a reference is to

from objects that she considers

as real as I could by noting in

eliminating these objects define such or

such type of city for example if we

takes Newton’s physics the one we

learn in high school for this physics he

there are three kinds of objects in the universe

there is space is the time ago there are

material body to empty

removed all the material body and

then there is empty space

that is to say without anything nada

the interior that spends its time

stay itself is equal to itself

very well except that physics we

uses today to describe the

matter is not at all that of

newton

it’s another physics called

quantum physics in physics

quantum when we remove the particles

all the particles we get a vacuum

which is not empty space

it’s a void that contains some

fatigued matter is besides

particles that are well and truly there but

which does not really exist what the

kind of ghost that he lacks

energy so that they can only

not materialize and they become

unobservable so-called

virtual particles and l snorts

in this emptiness way a little vegetative

like sleeping beauty

how to wake her up but he

give them an energetic kiss

that is to say give them the mega

electron volt that is missing at their full

the incarnation

to do this it’s very simple we do

high particle collisions

energy and its particles behave

like charming princes

microscopic

they give their energy to the void

quantum particle shot

virtual downstream this energy

become real and kind of empty

with an energy that can be very

long

she who was doing a long piece

since the beginnings of the universe found

the vitality she once had and

leave this landmark with an energy

colossal

when I tell you there is a void

quantum it reminds of a

intuition so great what a blush

pascal philosopher mathematician

physicist death pascal intuition that he has

in a letter in fact 147

letter he addressed to Santa Claus

so it’s not Santa Claus

firs

it’s the reverend Santa Claus who

was a Jesuit author of a book

titled the full of emptiness with which

obviously pascal blaise was not

Okay

and in this paschal blaise letter

writes this there are so many

difference between nothingness and space

empty that between the empty space and the

matter the living space says he holds the

middle between nothingness and matter

in other words, the status is empty

quantum that’s exactly the status that

blaise pascal attributed to the fast all

short

it’s a kind of prologue to the

reference state matter more

low energy everything emerges matter

such as we as the

know without them ever cutting

its umbilical cord the material remains

connected to the void from where it came out

then quantum physics is

obviously very complicated but in

big we can say it’s a physics that

describes all the manifestations of

physical world as excitations to

from this fundamental step of

the material from this void

quantum which is a kind of tuning fork

primitive of the universe so if I you

say this is simply because

the fact that the quantum vacuum backwards

of the meaning of words being complained may

inspire us

that is, it’s a metaphor

which allows us to think that eventually

to empty

that’s somehow doing the

full since empty and full but

so full of what I would take

the quantum analogue past the full of

desires for energy is the full in

life of passion

it’s full of existential libido

it’s full of self- events

in great vivacity and so my

advice is next next time

that you will have a pump stroke that you

you will feel complained of troubles a

go for a ride by thought in

this source of vital momentum that is the

quantum vacuum and you’ll see that pass

by this void there is the opposite

empty passage

the test of the lack of withdrawal from

calm that emptiness forces us into

bring out more alive more

delusional more end less banal and so

positively boosted me I leave you

think about it

hoping not to have spoken in the

empty

and especially by wishing you good

courage for this little meditation

philosophical fisico that I propose to you

with potentially stupefying virtues
