see the world in a grain of sand
or hold infinity in the hollow
of his hand
2 to an English poet William Blake
written two centuries tells a
bit is a summary of what
you could say the Grain
single grain contains the world
it is ultimately there are so
grain species everyone
mineral presents the SAP grains
and stones that can be
100 micron grit that may
be dust
it may be seeds which
carries life in the world
plant and it is really this
vast nature of forms of diversity
colors all you want
and then there ended in the palm of
hand is obviously that
pervasiveness of grains that these grains
covers 80% of the surface of the earth you
coverings obviously our planets
nearby
we will find in the rings of
jupiter finally made this
granular material is huge and
Universal is actually after
air if we want after water species
most common on earth is
rigorously banal commonplace it
is inspiring this is inspiring for
do what is called the matter
Grain kernels build with it
farts build a house that can
to make a pie dough
seed grain which it is simple
perhaps for Grain which I
want to talk to you starting with
our dear grain when can we
say, well first thing is
indeed it is a grain
endangered his not look like that
80% of the land realized that
indeed any materials the
even human construction you
do that this rag singing ten
in the hundreds of tons grain
which are transported e.g.
desert to make constructions
Parents are an estimate
14 billion tons or is that
beaches are getting poorer as
riverbeds also drag
So we have a poorer
actual grain loss is a danger
which seems quite trivial but
is quite real and you
Looks good it does not matter
grains for very long one
crusher used for in
careers to drop wines and
it is true that we can always do it
can even replace the crushed green
for the case is like the silica
to make sand however it
doesnt this is extraordinarily
Instead of breaking the grains poor
menders on the road to Louviers
he spent a lot of energy
just open these grains but creates
Heat still a little small
statistics you nothing to remember but
is large order of magnitude 30%
the energy consumed on Earth used to
break of the material as much as the
transportation we do not talk because
it is not noble did not
improvements that improves a
automotive
but it was very wrong the
things actually this energy it
and it is lost because this
material is blended or priest
not recover afterwards and therefore
this story is a story
dangerous and must be serious
attention in our consumer
Contents and the docks constructions
we can do with these guys then
this meaning of grains it is known
long time in the big century
classic which pleased jacqueline
romilly
there was Democritus Democritus will
introduce the concept of atoms what
does not cut its ultimate small grains
that seemed to go help
build strong dispute is
it moves a little damage or if it is
fully dispersed so the notion of
this granular material helps us
understand the material
we live in the material the
material world it continues and it was
Coulon who was an engineer who
were built bridges
slope of the problems that was the
bo é té world revolution
, Fight crystallography and then
it continues and I had practically
in all fields of technology
science and applications
we used the links so they
Grain Science I spoke of
Civil build a road
I not tell you the number of tons
but not of the considerable
material that is used to dig a
Tunnel also the name for the material he
must break the field Civil Engineering
vest trial as an excuse me genius
Process which is a very science
developed in this region if in
wherein the very finely divided material as
most proud coal will be brought
to burn more efficiently and therefore it
be reduced in granular powder while
they possessed relay Science
Earth particularly pedology
soil science in which
grains coexists with water air
with roots of the plant with
mineral course with them all
small animals that live in it so 7
it was this whole grains
is the ground and the subsoil
Environmental Science all
World Talk and rightly we
take a landslide
comprises an avalanche comprises a
scree include forming a
dune
these are subjects that interested
as a loose community but I
wanted to say this was science
plural grain 30 years ago with a friend
Gilles expensive stone that gennes
I worked 50 years of my life
we asked if we could not
do instead of down and a grain
Grain Science and start what
because it simpler a bag
ball
no high-tech as one puts
beads together as one makes a
Pyramid bi how is poured
debits from turkey
just to dress like a bag
they are made to vibrate so we Laye
created in France
a school on this science
grains and why we supported
the fact that we knew paradoxically
much better how atoms
moving in a solid than knowing
that when we degrade and thus places
used what made us all
called atomism the tiny
to try to understand larger,
we built this science to
time I wrote a book
was called BioTalent sand bag
it really was the bag of marbles
Model prince william he knew nothing
but it will come and so during its 30
years so we developed this
science it has become
internationally highly developed
you have a magazine like Nietzsche
very serious hours you find out
coverage is why there come a
sand castle I will talk again
like when you put the water not
not too little troop then so is
we are notified
I am advised me to describe this book
that came out to 15 days Thursday jacob g
combine two two young Jean-Yves friends
aisne and Farouk Rajai them that
themselves are in charge of this year
World Congress
not regret for grain which
held in Montpellier in July
so see news
Work was being done on it not
that this book then I think we described a
slightly different situations
wherein grains exist in
wherein working with grains in
which they are used to a lot of
science and I think
indeed new issues but
point will be moved because obviously
than what we got
is a particle engineering is
over only the ball is really
grains which are forms that
is attached in a way that
allows different constructions
not if it happens to be
used by the computer Dutrey jeans
not this little small dish
structure we can help to make
macroscopic structures so they
will have prices
and in particular this is
calls ref willingly these houses
scale not by microscopic
great building but it’s at
the intermediate material then
must of course I’m talking about
some concrete things that
I could have material you describe
examples in all fields
Application show you how
finally in orbit returned it
uses the porous ceramic for
power and prevent raids to
allow cooling I could
show you the contrary command is
rather ultimately ceramic
uses opposite Grain
extremely dense etc.
I could have taken any other
Just as you want then I chose
take one of the field
construction
then this field of construction
an area that is dear to us and you
will see that it is involved
off intervenes in
problems yesterday but also
problems of tomorrow then the first
view actually shows you the
fascination we all have round
where is it
as we all have for these
grain sand castle
Castle our children about what
is that a sand castle that is
nothing other than grains of sand which
were bonded together by
small beautiful feydeau called
capillary deposit capillarity
this is what makes your hair that
So it seems when you go
with Apec with water but it is
This capillarity it works well
if there is water, but if you would not
there it was asked
scholarly controlling the volume of purchases
rate of sand grains takes these
what they need to
last longer and so it is important that
we can add to it so we go
add clay
so this serves as a first model
the first model of our childhood but
it illustrates well enough what I want
say
the second course nature does
has not waited for us
Here you have a model of a
anthill as it reminded them
meeting of Central Africa
those below them can do something
6 thing as human raise
termite termites have the
made by mixing their slime their
saliva earth grain grain
sand and sun having dried
ferrand real welding
consolidate its grain and they will
make rooms they will make
corridors
they will make a vent
Ventilation these countries are wet and
eschau and this is just a model
construction do not know if
mankind has used in its models
East Africa but in any case there
these buildings served by this city
étaples of Manhattan and often the
desert and ban d in yemen Chibane you
have buildings that need 30 meters
back quickly floors constructed before the
pre-Islamic period, therefore it is not
yesterday and continues to exist quest
World Heritage of Humanity
but it is only very very
many examples of the cabin
up houses highly evolved
up mosques use
this particular material
Africa
but what is this building are
truly part of the past
answer is no
they are part of you today
There are two billion people on
earth who live in a habitat
grain material here that I you
shows her breasts winners
Mr. charm of a gun prices
called tera watt is given to
best building architects
model it is a village in China
destroyed in 2008 by an earthquake
earth the Chinese peasants and road
formed to make land habitat
have built their habitat locally
and this being what is fabulously
why significant because they
do not use the cement is cement
a is a producer of carbon dioxide
fabulous
passing carbon notation Mr. diop
you send co2 no choice
if you use a material UN
vernacular actual construction
used by local resources
Well you of course makes
this transport economy this
economy of the use of cement
So I think there really
for the future of quite modest
the use of this construction
land and ecologically
extremely important
you will find in tera watt other
Examples actual construction
of all kinds that you actually
know we went from our models
the initial bag of marbles to
more advanced models of how to
effectively avoid these structures
degraded by the effect of humidity and
this is my last favorite and I was
chance to work in there
it is the concrete high
Performance is said many evil
Beto but these concretes have been
improved
created as the pantheon rome
first centuries AD
rediscovered in France in the 19th
century the great big projects
progress will be in the XXth
century has been there for some years
recent decades was
discovered these concretes high
performance and working in these
projects I understand we have
understand how we could improve
these materials by adding at wholesale
Grain little small up to
fine grains to toddlers
hombourg as the material that can be
until that is very little empty
doing it considerably strengthens
if the material on top of that there
adds fiber that becomes concrete
buoyant’ll earn more there
again saves more we
something hard – using cement
less CO2 to products but at the same
time is produced of the structures
light
that’s the fishnet you can
view from inside the MuCEM this
Modern Marseille museum
is what you guess what is behind
a walkway that rises to the
Fortress genre across the
old port and the gateway to 4 cm
thick that you are above
it is as if you were on a metal
elastic
So we made the
lightness
we realized elegance
a material which is obviously
initially not very appetizing
here is a little bit the examples
I wanted to develop by showing
how our search for this
grain engineering joined a
extremely important tradition
so I wanted to finish you tell
as well as scientist who headed
a school that cared about
literary and humanities
social
Well we found tremendously
applications in science
Social humanities this
material to gain imagine that here there are
a small fire that fires
enough to trigger for
actually make people leave
with the only emergency exit
what will happen exactly
as if you try to
do chickens in a funnel rice
Basmati’s real are they block passes
not people must not pass
much more time in case of panic
to evacuate worlds if you
have if you are like Sade in
normal output and made models
which is a granular model it was
Interested problems
congestion
it was interested in two issues
congestion is addressed a
Blame parking and then more
meaning and interested in the fact that
finally individual grief grains
it is an individual which are put
socializes together they make groups
How do we pass from the individual to
group organized themselves how these
exchanges anyway So here
it’s a little bit what I wanted
just say a last word because
I had the opportunity to lead not
and the discovery is that I could
really lead to youth
discovered he discovered as
School solid liquid
gaseous
a material that was sometimes solid
liquid default x games were times
everything else
sometimes not you and I could
lead young people to admire their
love do their walking on the
sand hopefully that small
walk on the sand with me that
we will not be too good after more
