00:00:01

1983 and zionist David Copperfield

00:00:04

demonstrates the main trick of his life

00:00:06

by making the statues of liberty disappear in front of

00:00:09

millions of television viewers and 20

00:00:12

witnesses, right at the foot of the monument,

00:00:14

David closes the statue with a screen

00:00:16

while a spotlight shines on it from a helicopter and the ground

00:00:19

and, on a signal, the screen falls down and

00:00:22

instead of 90 three-meter giant there remains an

00:00:25

empty space, an

00:00:27

amazing trick of magic, but most

00:00:30

of you, of course, guessed that the statue

00:00:32

actually did not move a millimeter,

00:00:34

but simply because it is impossible to

00:00:36

move 25 thousand tons of concrete and metal

00:00:39

in space in a second, anril

00:00:43

absurdity, the secret of the trick in the lighting, when the

00:00:47

screen was raised, the spotlight

00:00:49

was turned off around and inside the monument, and the platform

00:00:52

with the spectators was carefully turned at

00:00:54

that moment so that the bright lamps obscured

00:00:57

their view, it can be seen that when turning, here on

00:01:00

the radar a glare from the lamp moved, what

00:01:03

happened, the statue became completely

00:01:05

indistinguishable against the background of the night sky

00:01:07

so the trick would only work at night, and

00:01:10

these shots with an empty site instead of a

00:01:12

monument are fake, taken in another place, it’s

00:01:14

boring to find out the truth, it was just as offensive

00:01:18

as you to know that in fact the birds don’t

00:01:19

sing, but call for [ __ ], but what if I

00:01:23

told you that there is a scientific way to

00:01:26

return magic and make an object

00:01:28

disappear day or night if you want to

00:01:32

create truly fantastic

00:01:34

things beyond reality, then you

00:01:37

will have to create materials that

00:01:39

do not exist in this very reality and

00:01:41

which by themselves could not

00:01:45

appear here; they are called meta

00:01:47

materials for winter, which means beyond

00:01:50

and today we will plunge headlong into their world,

00:01:53

at first it will seem to you that I am

00:01:56

deceiving you, yes, I understand you, we

00:01:59

studied this topic for three weeks, it also seemed to us that

00:02:00

we were being deceived, but at the end of the issue you

00:02:03

will understand that science is the best illusionist

00:02:07

and any enough advanced

00:02:09

technology actually resembles

00:02:11

magic. Now you will find out whether it is true that

00:02:14

metamaterials do not obey the laws of

00:02:17

physics; is it possible to create an invisibility cloak?

00:02:29

why an engineer folds

00:02:32

giant origami, how to make things out of

00:02:35

thin air and why the number doesn’t

00:02:38

look like ours at all

00:02:39

[music]

00:02:57

space from here you can see a lot of

00:03:00

amazing or even mysterious things

00:03:02

colored lakes in the USA a hypnotic

00:03:05

spiral in the Egyptian desert a huge

00:03:07

pentagram in Kazakhstan a great

00:03:10

place for dark rituals Do you agree,

00:03:12

or these mysterious circles seem that

00:03:15

trees a kilometer thick were cut down here,

00:03:18

but how can you see hope from space from space?

00:03:20

It’s possible you need to know where to

00:03:24

look, look here, here is Indonesia, this is a

00:03:27

huge island of Sulawesi, let’s zoom in on this

00:03:29

area in the southwest and here is an island

00:03:32

semi abend with y-a- and what’s here next to the

00:03:35

huge letters hop, this is the hope

00:03:38

that we were looking for in translation from

00:03:40

English, but this is not an art object or an

00:03:43

illusion of our sick brain, this is a chance

00:03:46

to correct one of the most terrible mistakes

00:03:49

of humanity, and if you look at the letters

00:03:51

even closer, we we will see that these letters

00:03:54

are made of coral reefs two years

00:03:56

ago this place was lifeless because the

00:03:58

corals were killed by dynamite and

00:04:00

cyanide and such tin was used

00:04:03

for catching fish they began to grow reefs from

00:04:05

scratch with the support of the Shiba brand how it

00:04:08

works on these steel

00:04:09

structures called reef structures the stars

00:04:12

plant pieces of coral and then they

00:04:14

themselves grow into a reef, why is all this necessary? I’ll

00:04:17

explain if you do nothing, then in

00:04:20

20 years approximately 90 percent of all

00:04:22

tropical reefs will die and here

00:04:25

the day before only corrals and most of the

00:04:27

organisms that live in them will

00:04:29

disappear; tropical seas will turn into a

00:04:32

cemetery small fish will die,

00:04:34

those who fed on them, sponges and other

00:04:37

invertebrates sitting on the reefs will also

00:04:39

die out, 500 million people

00:04:42

will be left without food and income, and I

00:04:45

repeat, this will all happen in 2

00:04:48

sheba plan to slow down this

00:04:50

marine apocalypse their plans to

00:04:53

cover an area of \u200b\u200bwith reefs in 2029 20 Olympic

00:04:57

stadiums and you too can help this

00:05:00

mission need to do a very simple thing,

00:05:03

it couldn’t be simpler, just watch the

00:05:05

video on Shiba’s YouTube channel, here there is a

00:05:08

small playlist, the quality of the footage is no

00:05:10

worse than that of National Geographic or Discovery,

00:05:12

just a few minutes of your attention to the

00:05:14

juicy shots of the underwater world

00:05:16

skip advertising and money from

00:05:18

monetization of viewing will go to the

00:05:20

project fund, another fish like this will get a

00:05:23

new home, in my opinion, an honest exchange is like

00:05:26

watching in the animal world or films with a

00:05:28

bush, only you are not just looking at the

00:05:30

good old researchers, but you are

00:05:32

actually bringing benefits, remember, the

00:05:35

more reefs we will build today the

00:05:38

more unique animals will be left

00:05:40

tomorrow

00:05:43

and

00:05:45

[music]

00:05:47

and I if you have an apple in one hand in your

00:05:52

left and in your right hand there is also an apple

00:05:54

if you add them up you will get 2 apples

00:05:58

to the simplest mathematics but what if you

00:06:02

put an apple in one hand with an apple in the

00:06:05

other hand and get an orange

00:06:09

wow, this is almost impossible, but this is

00:06:12

exactly how composite

00:06:14

materials work or just composites in

00:06:16

composites, materials are mixed but do not

00:06:20

enter into a chemical reaction, instead

00:06:22

they are connected like concrete with

00:06:24

reinforcement inside, one material strengthens

00:06:26

the other and the result is a new

00:06:29

property that none of the components

00:06:31

alone has, here is an example: there is

00:06:34

carbon fiber, it is very strong

00:06:36

if you stretch or press it, and there is a

00:06:38

regular graph that becomes

00:06:40

brittle if heated, but if you combine

00:06:43

carbon fiber with a graphite lattice,

00:06:45

then we can get a new property of not

00:06:47

cracking when sharp heated up to 2000

00:06:50

degrees, so this material

00:06:52

is used for fairings of

00:06:54

ballistic missiles, and in shuttles it was

00:06:56

used to cover the places where the

00:06:58

nose and wings were heated the most, or here’s my favorite

00:07:01

example: a ship made of [ __ ] and sticks,

00:07:06

well, it’s almost pykerite, it’s 15 percent

00:07:09

sawdust, the rest

00:07:12

is ice essentially a dirty iceberg, and

00:07:15

this boat is made from it. Paykerite melts

00:07:18

much more slowly than usual and, yes,

00:07:20

it can withstand explosions like concrete, all

00:07:22

because sawdust reinforces thicker than ice and

00:07:25

conducts heat poorly. In the 1940s, the British

00:07:29

seriously wanted to build an

00:07:31

aircraft carrier out of paykerite, why

00:07:34

save on metal? During the war,

00:07:36

fortunately, it didn’t go beyond the model, it looks like a

00:07:38

floating barn, but we are not

00:07:41

interested in all composites, no,

00:07:44

for example, what’s surprising about the

00:07:47

brick itself is nothing,

00:07:49

but I’ll tell you anyway, it’s just dirt

00:07:52

mixed with straw from which you can

00:07:54

build houses, that’s all no today we

00:07:57

will talk about the most amazing

00:07:58

composites whose properties for scientists

00:08:01

sometimes sound even crazier than an ice

00:08:04

ship and meta materials in ordinary

00:08:07

materials to properties are determined by

00:08:09

chemical elements, that is, the atoms and

00:08:11

molecules of which they are composed,

00:08:13

for example, and gold glitters yellow

00:08:16

because atoms reflect the most specifically the

00:08:18

yellow part of the spectrum, but for

00:08:19

metamaterials, the properties are determined

00:08:22

mainly by the order in which these atoms are

00:08:24

arranged, that is, the strength of these materials is

00:08:28

not in what they are made of, but in how

00:08:31

they are made, not in chemistry but in geometry, you

00:08:35

know, and this allows us to create

00:08:37

devices which previously there were only

00:08:39

science fiction, for example, an invisibility cloak, but not

00:08:42

like Copperfield’s illusion, but a real one, with

00:08:46

the help of science, we see objects

00:08:48

because light is reflected from them and hits

00:08:51

us right in the eye, and so that you understand how

00:08:53

this principle can be hacked, let

00:08:55

me show you first the simplest

00:08:57

device for invisibility, the Rochester

00:08:59

cloak, in fact, it’s no cry

00:09:03

about 4 lenses like this, they first seem to

00:09:06

shrink the light beam and then

00:09:08

risk it back to life and as a result

00:09:10

we get this pocket where any

00:09:13

object will be invisible, this zone is a blind

00:09:16

spot if look straight through the lens,

00:09:18

look, we put a ruler in there and

00:09:21

it’s not visible, we put our hand in and it

00:09:25

also disappears, all because these

00:09:26

objects don’t actually stand in the way of the

00:09:28

light and because we

00:09:30

artificially jump off the skin or the light that

00:09:33

seems was supposed to go through the

00:09:34

object now passes by and the object

00:09:37

ends up in the blind spot pure optics

00:09:40

no electronics cost no more than 150

00:09:43

bucks super working principle to control the

00:09:45

movement of light to bring it to

00:09:48

our eyes and bypassing the object all that

00:09:50

remains is to replace this entire

00:09:52

structure with something more

00:09:54

universal

00:09:55

for one metamaterial so that you can

00:09:57

look from different angles, but how it will

00:10:01

work will make the refraction of light, that

00:10:04

is, it will change the trajectory of the rays

00:10:06

inside itself. Now I will take you by the hand

00:10:10

and walk you through the school course, and this is how

00:10:14

we usually see refraction when

00:10:16

light goes from one material into

00:10:18

another, for example, from air to water and at the

00:10:21

border it sharply deviates from the previous

00:10:23

trajectory, you yourself could see this in the

00:10:25

pool when your friend entered the input,

00:10:27

for example, and his lower half of the body was

00:10:29

distorted so funny that he was

00:10:31

holding his head on his hand, by the way, mirages

00:10:34

hot and cold layers of air appear for the same reason,

00:10:36

they refract the light

00:10:38

differently and as a result,

00:10:40

a reflection flies into your eye not from where you are

00:10:42

looking, for example, you are in the desert looking at the

00:10:44

foot of a palm tree to offend and the top of the

00:10:47

palm trees and because the light came this way

00:10:49

from the tops of a palm tree are refracted

00:10:52

several times in different layers of air and

00:10:54

then into your eye according to the same principle on a

00:10:57

hot day you see

00:10:58

a piece of sky on the asphalt in order for us to create an

00:11:00

invisibility device we will need to

00:11:02

perform the same trick as inside the

00:11:04

mirages but we will have to break the light under

00:11:07

more with more crazy angles, this is how

00:11:10

ordinary water bends light, whose

00:11:12

refractions ordinary physicists say that

00:11:14

it has a plus sign, but this is what a

00:11:16

substance with a minus sign could do, let’s

00:11:18

give it meta water, such water has not yet

00:11:21

been created by fish in this meta water from the shore,

00:11:24

it would seem to be floating in the air, so

00:11:26

if you ever see something like this in life,

00:11:28

you can start to worry until either you

00:11:31

are sleeping or your matrix is malfunctioning

00:11:34

because, as I already said, in nature atoms do not

00:11:36

assemble into such materials, but where can we

00:11:39

get them? We need to discover probably

00:11:43

new chemical elements yes no no

00:11:46

need we will assemble the atoms ourselves manually and

00:11:49

for this we will not need particle accelerators

00:11:52

chemists or new cells in the

00:11:55

periodic table instead of ordinary atoms we

00:11:58

will create meta atoms the trick is that

00:12:01

in fact it is and there it is assembled from hundreds

00:12:03

or even thousands of atoms but he is still

00:12:05

smaller than electromagnetic waves, so he

00:12:08

can gently move it if he

00:12:11

gets in its way, but wait, what do the

00:12:13

waves have to do with it? We wanted to move the color, well,

00:12:16

hello to high school, because light is not

00:12:18

only a

00:12:19

photon beam, it is also a wave, that light

00:12:22

behaves like a wave because that this is

00:12:24

part of a large family of electromagnetic

00:12:27

waves and here he is in this family, he is one of the

00:12:29

younger brothers, the wave of light has a length of

00:12:32

only a hundred nanometers, followed by

00:12:34

infrared radiation of hundreds of micrometers,

00:12:37

microwaves up to a meter long, and finally

00:12:39

radio, these waves can reach up to

00:12:41

several kilometers and for each from

00:12:43

these waves we can build our own

00:12:46

invisibility cloak if we select atoms

00:12:48

that are smaller than the wavelength from which we are

00:12:50

hiding because we need to deflect them

00:12:52

very subtly, so for wavelengths meta

00:12:55

atoms can be large like antennas and

00:12:57

for short waves they must be

00:12:59

tiny like a virus cloak -invisibility

00:13:02

is a set of atoms that

00:13:04

completely cover our object from all

00:13:06

sides like

00:13:08

rhinestones on Kirkorov’s suit and refract the

00:13:11

electromagnetic wave in thousands of different

00:13:13

places at the same time, like in thousands of small

00:13:16

pieces of glass, such a device forces the wave and at

00:13:18

the same time the rays to go around the object from all

00:13:21

sides and beyond it closes again into its

00:13:23

original form, like a black hole causes

00:13:25

the rays to bend under the ear, creating the effect of a

00:13:28

lens, but only our cloak should make

00:13:30

it even more invisible so that we do not notice

00:13:33

any distortion, but those who ran to

00:13:35

Uglich are working invisibility cloaks to

00:13:37

spy on someone in the locker room

00:13:38

wait, you will have some more time, we have

00:13:41

learned to hide large objects so far, they will be deprived of

00:13:44

microwaves and radio waves because for

00:13:46

large waves it is much easier to select meta atoms

00:13:48

and it is also easier to make a cloak,

00:13:51

for example, we take a cylinder like this that

00:13:54

we need to hide like this, a radio wave

00:13:56

passes through it without masking and

00:13:58

bounces off in all directions so that

00:14:01

any fool with a radar will notice it, and now

00:14:03

we place our cylinder inside the shell and

00:14:05

Smith material, that is, metal

00:14:07

plates printed in ceramics in a

00:14:09

certain order, now the wave

00:14:11

calmly passes through the

00:14:14

shell objects as if there were no

00:14:16

obstacles with such a coating You can,

00:14:18

for example, upgrade stealth technology for

00:14:21

airplanes, now it works like this: a

00:14:23

radio wave from the radar hits the airplane

00:14:25

invisibly and scatters in any

00:14:28

direction, just not back to the radar that

00:14:30

could catch it, it’s all about these

00:14:32

flat surfaces on the skin

00:14:34

located at pre-calculated

00:14:36

angles, but here the problem is that modern

00:14:38

radars can detect invisible people with

00:14:40

waves of a different length, but if

00:14:42

invisible people had a coating and an estimate

00:14:45

of material, then the same radar

00:14:47

releases a wave, the wave flows around the plane and

00:14:50

flies off somewhere into infinity, everything is

00:14:52

super, unfortunately, with visible light, until

00:14:55

such a trick can be pulled off but we can’t and

00:14:57

why, well, there are many reasons why, not only are

00:15:01

we meta, but we must be

00:15:03

several times smaller than the wavelength of light from 100

00:15:05

nanometers and less, and

00:15:08

we can only put the

00:15:10

same small objects 15 times smaller in width and in invisibility cloaks

00:15:13

human hair, scientists believe that it is

00:15:15

impossible to hide something large like

00:15:18

a person with this material alone, because a

00:15:20

person is not a cylinder, we have very complex

00:15:23

shapes and it is difficult to disguise us from an

00:15:26

observer from all sides; in addition,

00:15:29

there is another bug when light bends around an

00:15:32

object along a longer path then there is

00:15:34

along this arc and the light nearby passes in a

00:15:36

straight line, then our eye immediately notices

00:15:38

the delay and the brain thinks someone will still

00:15:41

exchange something, they are deceiving here, and

00:15:43

finally, the most obvious tank of the

00:15:46

invisibility cloak is what if you force

00:15:48

all the light to bend around your body then every

00:15:51

photon will go around your body, including your

00:15:53

eyes, and you yourself won’t

00:15:55

see anything, but it will just be that you go blind,

00:15:57

and you can make a hole in the proceeds for the eyes,

00:16:01

stick your eyes out and that’s all, and that it will

00:16:05

just scare your observer like some kind of

00:16:07

[ __ ], this is the situation, simple food and

00:16:09

the eyes hang scary, in general, where you

00:16:13

want to peek, it won’t work, I’m talking

00:16:15

about this, but that doesn’t mean that all this is

00:16:17

hopeless, you can connect active

00:16:20

camouflage that works on electronics,

00:16:22

but there are such miracles too, and most

00:16:25

likely 1 invisibility suit will

00:16:27

look more like Harry Potter's robe, that is, a

00:16:29

rag with ideal properties, it is an

00:16:31

adaptive predator suit that

00:16:33

runs on batteries and roughly imitates

00:16:36

what is behind, like a million or a

00:16:38

cuttlefish, it will only be an illusion of

00:16:40

invisibility, camouflage like the rather

00:16:43

primitive developments of quantum, a stealth shield

00:16:45

made of several lenses does not allow you to see

00:16:47

the reflection from the object in the center, shielding

00:16:50

it with light from the edges, yes, the person in is not

00:16:52

omnipotent until we can’t make a damn

00:16:55

invisibility cloak, that’s what we do, but it

00:16:57

turns out with varying degrees of success, but it

00:17:00

surprises, it surprises me, oh

00:17:02

well, why do you need to hide why

00:17:06

hide who are you afraid of

00:17:08

shout about yourself on board dye your hair

00:17:10

dress up in a fishnet dish like marilyn

00:17:14

manson attract attention

00:17:15

earn subscribers money later and

00:17:18

sell your courses on successful life

00:17:22

and then everything is fine with you but look

00:17:26

I want to continue the issue and move on to something

00:17:28

very interesting question question such a

00:17:31

time we cannot subjugate all

00:17:32

electromagnetic waves yet

00:17:35

can we fix some other

00:17:37

waves for example sound sound this is also a

00:17:40

wave spoiler until we can and now you

00:17:45

will see a black hole that can save

00:17:48

your party

00:17:49

from the police but finally- then, well, they’ve finally invented it,

00:17:52

it’s built on the principle of a

00:17:54

labyrinth, the further the sound travels inside,

00:17:57

the more it encounters walls, gradually

00:17:59

being absorbed and losing its strength by 99

00:18:02

percent; this, for example, you can line the

00:18:04

walls of an apartment and not worry about the neighbors

00:18:06

hearing the noise or extinguishing

00:18:08

all unnecessary noise with this black hole for sound noises from the back

00:18:11

side of the speaker, yes, you can say I

00:18:13

- we already know this; in recording

00:18:16

studios there are these sharp

00:18:17

triangles in anechoic chambers, there are

00:18:19

these scary walls with big huge

00:18:22

things in meta materials, the principles

00:18:26

seem to be that geometry also works here, but

00:18:29

it’s more about whether you’re ready you glue

00:18:31

giant ribs and pyramids all over the wall and are

00:18:34

not ready to look at the pattern from the

00:18:36

labyrinth on the wall, the answer is obvious

00:18:41

and

00:18:44

finally weather news Sunday

00:18:47

at the beginning of the work week in Moscow the

00:18:48

hot weather will continue the abnormal heat is

00:18:51

not going to leave the capital weather forecasters

00:18:54

say that Muscovites are waiting for new sweltering

00:18:56

records already now the temperature outside the window is

00:18:59

36 degrees and at night it will drop to

00:19:06

but it will endure

00:19:18

[applause]

00:19:28

[music] and

00:19:44

[music]

00:19:56

upgrade your thermal camouflage with a new

00:19:59

deodorant flash drives from Neva and I

00:20:02

get out dry from any sweaty situation

00:20:05

splashed and we are at least five

00:20:07

percent of your skin no more sweating

00:20:09

from the heat, this ad is dedicated to everyone who

00:20:11

survived the abnormal heat of Yulia and special

00:20:15

respect to those who have unshaven armpits, but

00:20:18

I will continue the release with fresh ones and

00:20:22

so here’s an interesting question: if sound is

00:20:26

also a wave, like light, can we

00:20:28

collect similar devices for it and

00:20:30

control these waves, for example, if

00:20:33

we can assemble a lens for light, we can also

00:20:35

assemble a lens for sound, of course, from

00:20:37

different metamaterials in the shape of bricks and

00:20:39

refracting the sound in any way we can actually even

00:20:42

make it so that at one end of the room

00:20:43

a person will listen to one sound and at the

00:20:45

other end of a completely different

00:20:47

UK a prototype of

00:20:49

a device similar to a

00:20:51

camera lens has already been developed, but with two acoustic

00:20:53

lenses inside, such a thing can

00:20:55

focus sound waves into an area

00:20:58

the size of a ball and even track

00:21:00

your position in space while you

00:21:02

move to send sound clearly to

00:21:04

your ears without people around even

00:21:06

hearing what kind of music are you

00:21:08

playing now all the light and sound to some extent are

00:21:12

officially in our pocket we can either

00:21:15

create waves that are worse than waves in

00:21:19

solid objects and the same principles of

00:21:21

constructing materials can be transferred from

00:21:24

the microworld to the macroworld and they will

00:21:26

work, for example, to save us from

00:21:29

earthquakes, as we remember from the issue

00:21:31

that are hidden under our feet, an

00:21:32

earthquake is also a wave from but

00:21:35

it moves inside the earth to

00:21:37

extinguish it in San Francisco, for example, houses

00:21:39

are built on a movable foundation so that they do

00:21:41

not collapse but simply sway, but in

00:21:44

Japan you are constantly shaking there Since the times of

00:21:47

ancient pagodas, a strong rod has been placed in the center of buildings,

00:21:49

and now it has migrated

00:21:52

to skyscrapers where a whole building hangs around it on ties,

00:21:54

that is, now

00:21:57

every building is protected as best it can from an

00:21:59

earthquake, but what if the entire

00:22:03

city is protected at once at the design stage, if

00:22:06

houses are built in the city in ascending order to the

00:22:08

center, then each of them will

00:22:10

vibrate, taking away energy from the seismic wave,

00:22:13

and together they will protect the central

00:22:16

square and make it invisible to

00:22:18

earthquakes and also reduce destruction

00:22:21

in at least half of the city, a

00:22:23

good concept, but what if we don’t want to

00:22:25

build a round city, we want to protect

00:22:27

existing ones, you can

00:22:30

plant rows of trees near residential areas or simply

00:22:32

drill holes in the ground and they

00:22:34

will also tremble and dampen technical waves.

00:22:37

You see, the principle of creating order to

00:22:40

dampen the wave is

00:22:41

universal, but I don’t want you to think

00:22:44

that metamaterials are only about waves,

00:22:46

this is how to control them with their help, you can

00:22:49

create a new reality where physics

00:22:51

behaves very strangely, well, for us it’s

00:22:54

strange for us large creatures, this

00:22:57

is called on the range, this is the world on a

00:23:00

scale from 1 to 100 nanometers, and what is

00:23:03

so surprising in this range

00:23:05

from and what is here the chemical properties of

00:23:08

matter large piece of matter that

00:23:10

we see generally stop working on

00:23:12

them, quantum effects begin to dominate,

00:23:15

for example, gold on this scale

00:23:17

no longer shines yellow, its color

00:23:20

changes from red to purple

00:23:22

depending on the size of the particles, and if you

00:23:25

make even smaller nanoparticles, but

00:23:28

not gold, but from semiconductors, then

00:23:29

we will get the most luscious dyes - quantum

00:23:33

dots;

00:23:34

if previously, different chemicals were needed to paint each color,

00:23:38

for example, to make red you need

00:23:40

separate chemicals, others are

00:23:42

needed to make blue, but now

00:23:44

we have a whole light constructor and,

00:23:47

most importantly, from the same

00:23:49

substance. out of 15 atoms, when a

00:23:53

photon hits, it gives us a rich blue color,

00:23:55

add another 15 atoms and the quantum dot is

00:23:58

already green, and so we reach 150 atoms,

00:24:02

having received the entire spectrum of the rainbow, quantum

00:24:04

dots have been working for a long time, crooked matrices

00:24:06

in TVs where I drink means quantum and

00:24:09

such a bright contrast picture they

00:24:12

produce in comparison with LEDs, and in

00:24:14

ordinary TVs here you can get

00:24:16

more accurate colors as in nature, but these

00:24:19

were all chaotically scattered

00:24:21

nanoparticles and if you combine them in a

00:24:24

strict order you will get the second

00:24:26

cool property - incredible strength, but

00:24:30

for this you will need one more

00:24:31

ingredient, ready to find out what kind of holes the

00:24:36

more holey your material is, the

00:24:38

stronger it is I understand yes it sounds somehow

00:24:41

illogical because a holey wall a holey

00:24:43

bridge support a holey condom should be

00:24:45

less durable than whole ones yes that’s all true but

00:24:50

here

00:24:51

the size matters if you press a cube of

00:24:54

ceramic tubes 50

00:24:56

nanometers wide with a press then at some point the material

00:24:58

will not hold up and will sharply flatten, this is

00:25:01

because the cube is made from fragile ceramics,

00:25:03

no, everything is because it is simply not

00:25:06

holey enough, okay, let's make the tubes

00:25:09

5 times thinner and the material with absolutely the

00:25:12

same chemical composition can be compressed

00:25:15

twice as much and then we will also

00:25:17

establish its shape and so let’s

00:25:19

once again it was ceramics like from ordinary

00:25:22

earthenware, but it was

00:25:25

only 0.1 percent, all the other

00:25:28

ninety-nine and nine percent

00:25:30

were holes in the air, the material is so light

00:25:33

that it holds on to a dandelion or there is

00:25:36

no photoshop here, a whole sea of

00:25:38

variants of these lattices with different

00:25:41

chemical compositions has been created and it looks like

00:25:43

architecture on a nano-scale, some

00:25:45

even look like the Eiffel Tower, and in

00:25:48

2020 they created a lattice of simple

00:25:51

carbon atoms that reached the

00:25:53

maximum possible strength for all

00:25:56

porous materials there is

00:25:57

simply nowhere to improve further, but why are they

00:26:00

all so strong because if you take

00:26:02

molecules and build a lattice from them cell

00:26:05

by cell on the nano-scale, then there

00:26:08

will be no cracks there, and if there are no cracks and

00:26:10

defects on the nano-scale, then

00:26:12

strength at the macro-level will be super

00:26:14

high, that is, if there are no problems at the

00:26:18

small level, then at the large level everything

00:26:21

will be perfect by the way, the golden rule in

00:26:23

life straight from engineering, you

00:26:26

can build light and strong structures from such materials every day,

00:26:29

for example, I don’t know where the orbital

00:26:31

station or colony is on Mars, after all, every

00:26:34

kilogram to lift into space costs a

00:26:37

lot of money.

00:26:38

Even cyborgs can be built from the lattices,

00:26:40

and if patients are diagnosed with

00:26:43

bone cancer, the diseased area must be

00:26:45

removed. Doctors have already tried the great

00:26:47

idea of printing an exact

00:26:50

copy of this area on a 3D printer and inserting it

00:26:52

as a replacement. Includes: poured in, but if you

00:26:54

use metamaterials for this

00:26:56

on the gratings, the implant will be even lighter and even

00:26:59

stronger, and real bone tissue

00:27:02

will be happy to settle in such

00:27:04

on the frame as corals on artificial

00:27:06

structures, although to create them you

00:27:08

need a not quite ordinary 3D printer, they are

00:27:10

literally burned out on the gratings shooting one

00:27:13

cartridge at another photon into drops of resin in

00:27:16

layers one atom thick, so while

00:27:20

such things are not being made on an industrial

00:27:22

scale, they are expensive for a long time and go find a

00:27:25

photon printer, but we have

00:27:27

another class of materials that are also 99

00:27:30

and 9 composed of air - airgel and they

00:27:34

either launched a

00:27:35

constant stream of general production

00:27:38

already, yes, they look like liquid gummies

00:27:41

from which you pumped all the liquid and

00:27:44

add gas so they look like

00:27:46

something drawn with computer

00:27:48

graphics airgel, solid and withstands heat very well,

00:27:51

insulates heat on the

00:27:53

veritasium channel, he protected the presenter from

00:27:56

flamethrower, but the airgel came out 1 on 1 with

00:27:59

hot lava and remained intact, you can

00:28:01

make a suit for volcanoes and crossbars out of it,

00:28:04

this is not just a prototype and a toy,

00:28:08

they already left the laboratory and flew into

00:28:10

space. NASA used quartz

00:28:13

airgel for its stardust mission to

00:28:15

catch particles from it. comets Windows 2

00:28:18

and on the last Mars rover Perseverance the

00:28:20

airgel plays the role of thermal insulation

00:28:22

by the way, who doesn’t remember about the graph but the graph

00:28:25

here is the one that

00:28:27

was on the hype a few years ago, there were a whole bunch of articles about him

00:28:31

that he will revolutionize science, that soon

00:28:33

everyone will know about him and everything will be from

00:28:37

graphene it is ordinary carbon, like a

00:28:39

pencil lead, but while you live in a

00:28:41

three-dimensional world, the decanter has a thickness of

00:28:44

one atom, that is, it is almost two-dimensional

00:28:48

so that it is clear what I will explain on the

00:28:50

sheet, the decanter has a primary width and

00:28:54

length but is only 1 atom thick if

00:28:57

you turn it over like this

00:28:58

[music]

00:29:02

it will almost disappear and at the same time it is wildly

00:29:06

durable and conducts current very well

00:29:08

airgel and decanter are cool materials but

00:29:11

this is not a meta material then why are they talking about them

00:29:13

yes many of you understand but there are

00:29:16

2 cool materials then

00:29:18

why I would like to say it connects with

00:29:21

together that this will, of course, turn out to be

00:29:24

the best building material on the planet

00:29:28

meta brick is not a joke you need to build a

00:29:32

metro city of beaten bricks if a

00:29:35

meter of brick fell on your head you me to be

00:29:37

ironic here graphene airgel is an

00:29:40

excellent performer among all metamaterials in

00:29:43

all respects stronger steel, but at the same time

00:29:45

500 times lighter and it lies like flowers,

00:29:48

withstands heating up to seven hundred and fifty

00:29:50

degrees, holds its shape when compressed up to 90

00:29:54

percent and absorbs liquids a thousand

00:29:56

times more than its mass, and the Chinese have already

00:29:59

been able to make bricks out of it and want to

00:30:02

build graphene zaire and air

00:30:05

locks, well, yes, that is, literally locks out of thin

00:30:07

air, you understand the graph, the new airgel is like

00:30:10

that, I’m the coolest, you beat me, I’m the most

00:30:12

durable, I’m also generally idle, I can

00:30:16

absorb water, how much water I can absorb all of it,

00:30:18

and at the same time, I’m the lightest,

00:30:23

we’re friends, and so what I want to say is when I

00:30:26

I’m talking about these things, I feel like you

00:30:28

know, a salesman of air because

00:30:31

I say scientists have created a prototype or

00:30:33

scientists have come up with new innovative

00:30:35

materials and it seems that

00:30:39

all these developments remained on paper

00:30:42

or somewhere in

00:30:43

ted speeches, but not this time I

00:30:47

like to repeat that the future

00:30:49

has already arrived, we just didn’t notice it,

00:30:52

so metamaterials have become a part of everyday

00:30:55

life, new satellite dishes

00:30:57

no longer look like wide dishes, now they are

00:31:00

flat pancakes that catch a signal from

00:31:03

any side, they don’t need to be rotated and

00:31:05

you can even put everything on the roof of a car

00:31:08

thanks to the fact that every meter and there it

00:31:10

works as a separate antenna that

00:31:13

can be very finely tuned, but

00:31:15

special glasses made of materials already

00:31:18

protect pilots’ eyes from lasers, and

00:31:20

yes, in 2021 there are still a lot of idiots

00:31:23

who shine into the windshield of

00:31:26

airplanes, burning out the pilot’s retina, why,

00:31:29

but aux ethics that when stretched, they do

00:31:32

not thin out, but on the contrary, they become

00:31:34

wider; they make excellent

00:31:36

shock-absorbing soles for sneakers; and

00:31:38

very soon a blood sugar meter will appear

00:31:41

that will not need a single

00:31:43

drop; cut; the device will simply send a

00:31:45

radio wave through the tissue between the fingers; At

00:31:50

the exit,

00:31:52

the device measures glucose because it has a

00:31:55

special effect on the passage of radio waves

00:31:57

and some conditional jarakhov will be able to

00:32:00

measure sugar without pain at the moment at least

00:32:02

every five seconds, there is also a film that
