for him time flows differently he can00:01:46
watch some process00:01:49
on Saturn for weeks00:01:50
my baby is so addicted00:01:53
baby what if something happened00:01:59
if something happened happened, he would definitely00:02:02
write, so why write00:02:04
if everything is fine, you’re probably right,00:02:19
your dad is my baby,00:02:23
everything’s fine with me, I said hugging00:02:29
your baby, it’s clear that it’s a miracle, but that’s00:02:34
all, but he’s fine, that’s00:02:41
the main thing, I can’t so00:02:48
I need to see more my boy can the00:03:00
MKA baby fly on a rocket it’s too00:03:05
long and dangerous I need a device that00:03:11
allows me to see my boy a telescope00:03:15
[music]00:03:25
ain telescope don’t come too00:03:29
far baby I need to make a device00:03:32
that transmits the image at00:03:35
a distance and I can see how the baby00:03:39
waves his hand at me how he will send you his photo00:03:43
from space00:03:44
I’m not talking about a photo, I’m talking about a00:03:48
moving image, how is this even possible in a movie00:04:08
[music]00:04:25
wait00:04:29
Vladimir Kozmich Zvorykin was the first to assemble a00:04:32
working device with00:04:34
which you can transmit and receive00:04:36
a video image this event happened in00:04:41
1931 the inventor00:04:44
was 42 years old at that time00:04:46
[music]00:05:01
today the descendants of this device are in00:05:04
every home and even small children know the words TV00:05:09
[music]00:05:15
I still don’t understand how00:05:18
the image can be00:05:19
transferred somewhere, very simply you need to00:05:23
split it into small pieces and00:05:25
pack and send I know when we00:05:31
watch a movie we actually see00:05:33
many separate pictures that00:05:36
change very quickly the entire image on00:05:39
the screen consists of such frames when00:05:41
changing frames quickly you get a00:05:44
single moving picture so in order to00:05:47
send the image somewhere you need to00:05:50
first split it in the picture frames,00:05:53
each picture frame will also have to be00:05:56
broken into pieces; the image consists00:05:59
of many small dots so00:06:02
small that we can’t even distinguish them00:06:04
if00:06:05
we transfer information about00:06:08
each such point from one place to another place and00:06:10
add these points there into a frame, and then in the00:06:13
final result we will get00:06:15
moving images00:06:18
[music]00:06:25
but it can only work out how to00:06:32
see this image, we need something that00:06:36
could bista draw these dots00:06:58
the image can draw a beam it will00:07:01
move through the games if the beam path00:07:03
moves quickly00:07:04
we will get 300:07:07
TV screen consists of individual points,00:07:10
as well as the image transmitted through it,00:07:12
these points are called pixels, in00:07:16
accordance with the information received, the00:07:18
TV lights up the necessary pixels on the screen00:07:21
and we see a certain00:07:23
picture, why is00:07:24
everything black and white00:07:29
not configured or what? there are00:07:37
too many00:07:39
multi-colored people, it’s difficult, but I00:07:44
read somewhere that there are only three primary colors and00:07:47
all the rest are already lower00:07:54
compression, how could I forget there is me and00:07:58
Tristan this is red blue and green00:08:03
I can get the whole color palette with00:08:06
just three colors red00:08:09
green and blue if the rays of the00:08:12
corresponding colors are projected onto a00:08:14
white background with varying degrees of brightness, we00:08:17
get all the other colors; when mixing00:08:22
red and green, we get yellow;00:08:28
adding green and blue, we get00:08:30
sea green;00:08:33
and when mixing red and blue,00:08:36
purple;00:08:38
if we cross all three rays,00:08:41
we get white color I can see00:08:48
my boy colored gospodar went color00:08:56
now you need to send the camera baby00:09:18
let's go00:09:22
and you will receive a radio signal with00:09:27
a video image00:09:29
the signal will go to this antenna and through00:09:32
it to the TV and the TV will remake the00:09:36
signals picture if you force the00:09:43
electron to move in one direction or the other00:09:46
from waves will spread out00:09:49
like a float on the surface of a pond,00:09:51
these waves are called electromagnetic00:09:57
light, these are also electromagnetic waves,00:10:01
electromagnetic waves can00:10:03
spread everywhere00:10:05
even in space between planets and00:10:08
stars,00:10:11
register electromagnetic waves,00:10:13
we can see and hear what00:10:16
is very far from us when00:10:19
electrons move in the transmitting antennas,00:10:21
waves appear00:10:23
that scatter in all directions00:10:25
[music]00:10:27
the antenna of the receiver catches these waves and they00:10:30
force the00:10:32
electrons of the receiver to move in the same way, so you can00:10:36
transmit00:10:38
sound and image of comfort at a distance, but it’s snowing, this is00:10:45
interference, the signal hasn’t arrived yet dank balls00:11:05
Vladimir00:11:07
[music]00:11:15
well - so long as your TV isn’t broken00:11:18
and I’m here a little bit meeting00:11:24
our device and in order to better see this00:11:38
future television00:11:44
[music]00:11:46
she started up00:11:50
we baked a loaf, such a wonderful00:11:58
number Russian folklore00:12:02
I couldn’t even dream of, did00:12:05
you really think we wouldn’t have one for00:12:08
you good gift, do00:12:11
you remember I wanted to know about these00:12:15
leggings00:12:16
and the pages of your encyclopedia were torn out00:12:21
annoyingly I don’t know how this00:12:24
could happen the encyclopedia is a source of00:12:28
knowledge a source in which every00:12:31
sip is important in short we ordered two new encyclopedias for you00:12:35
[music]00:12:39
come on, everyone a sip on the spot 400:12:48
let's already see why this is evil ranks00:12:52
such excellent books are better to read in00:12:59
order00:13:00
first like this the letter L inside is a salmon elk00:13:06
and you do this you're a celebrity and you were00:13:15
silent a modest fellow it00:13:17
can't be this is some kind of mistake no00:13:23
no no00:13:24
it's definitely written here elk00:13:28
scientist loser was expelled from00:13:31
the committee inventors for an extremely stupid00:13:34
discovery there is also a region hrc00:13:39
complete the silly one make a ridiculous mistake00:13:44
another uniform you wear a baby sew00:13:54
yes00:13:56
yes this is the honest truth post00:13:59
sorry for not telling you00:14:03
earlier about this shameful page of my00:14:06
biography this happened on the biggest00:14:10
international congress at the very beginning of00:14:13
my scientific career, I was young,00:14:16
ambitious and really wanted to get into00:14:20
history, dear colleagues, well-known00:14:24
gases, as we know, enter into00:14:26
chemical reactions with other substances,00:14:29
for example, oxygen, which surrounds us everywhere,00:14:32
if not for its ability to00:14:38
enter into chemical reactions, we would00:14:40
literally we were able to breathe00:14:42
many gases unpleasant approach for example00:14:46
hydrogen sulfide kiomi00:14:47
[music]00:14:51
others are simply dangerous for example chlorine as close as possible00:14:59
where are the properties of gases we all know very well here00:15:02
yes yes of course and today I would like to00:15:06
give the world my discovery of amazing00:15:10
gases that do not enter into00:15:13
any form at all reactions, such gases00:15:16
really exist, it was difficult to00:15:19
detect them before because they do not smell,00:15:22
have no color, and otherwise we are not00:15:25
in contact with anything else at all. For this00:15:27
ability, I decided to call them00:15:30
noble gases, or more scientifically, in00:15:37
ours, they are also a good name,00:15:42
just like that I discovered exactly 6 noble00:15:46
or, if you like, inert gases, this is helic00:15:51
not he00:15:52
archon krypton xenon and radon00:15:55
why don’t they enter into any00:15:58
reactions as you know atoms consist of a00:16:02
nucleus and rotating or suddenly often one00:16:06
more unit from them together forming a00:16:08
molecule to hold them together there must be an00:16:11
electron of one of the atoms for this, the00:16:14
second atom00:16:16
must have a free place for it, the00:16:18
atoms of ordinary gases have free00:16:22
places g electron, so they easily00:16:25
react with other substances, but the00:16:28
noble gases have no free places and00:16:31
therefore there cannot be reactions simply00:16:35
like everything is ingenious, besides, my00:16:38
noble gases are very rare in our00:16:41
atmosphere, the most common one is argon,00:16:45
but it also makes up only one percent of00:16:48
all other gases of the00:16:50
earth,00:16:51
tell me halal, what is the practical00:16:55
use of these00:16:57
gases of yours in the reaction, they do not smell in the light, they00:17:01
have no use for yours00:17:05
discoveries, but to be honest, I didn’t think for00:17:09
sure there would be any benefit, I was thinking00:17:16
about something alive then I wanted to say if00:17:26
you look for reconciliation, you will00:17:30
definitely find it, in some sense, my dreams00:17:35
came true, I really left00:17:38
my mark on history and was included in all00:17:42
encyclopedias,00:17:43
but not quite like that As you expected, you00:17:48
won’t figure out00:17:50
where to use your noble basins,00:17:54
the only application I found was00:17:56
inflating balloons with helium,00:17:58
after all, it’s lighter than air, my discovery was00:18:02
recognized as the most useless in the entire00:18:04
history of the Academy of Inventors, it’s a shame,00:18:09
I don’t see anything shameful, you never know where00:18:12
I lived before I mean, it’s a00:18:16
young thing, that’s it, and you’re already getting00:18:19
older, thank you, and that in your committee of00:18:23
inventors they understand about entertainment and the00:18:26
balls are00:18:27
great, raincoats, you don’t take it to heart,00:18:31
but if necessary, we’ll anta00:18:35
encyclopedia mind cyclopia Dima00:18:38
yes00:18:47
[music]00:18:54
we00:18:56
[ music]00:19:05
this is the worst birthday of my life, it00:19:10
could be the last LED ball,00:19:15
the motor is very damaged and the00:19:19
communication and work work, we can’t even00:19:22
call for help somewhere we happened to be near the00:19:36
planet Tsa, this is Mars, its00:19:40
satellites phobos and deimos are hanging over there00:19:43
with talent earth in the sky see it if00:19:47
we had a telescope there is then it will not00:20:05
help with all due respect you are too00:20:08
small an object for astronomers then00:20:11
let's light a big signal00:20:14
fire on Mars there is very little oxygen00:20:17
here nothing will burn then we00:20:22
need a light bulb a large electric light00:20:25
bulb just something On Mars, a00:20:28
factory of00:20:30
giant electric light bulbs just recently opened; however,00:20:35
theoretically, it could be a gas00:20:37
lamp, it is easier to manufacture, and a00:20:41
glass tube can be filled with an00:20:44
ordinary gas, such as nitrogen or00:20:46
carbon dioxide, and pass00:20:49
electrons and ions through not youtube in00:20:54
a year, they will touch it from you and causes00:20:58
them to glow, such a pack will00:21:05
heat up much less than a regular00:21:08
incandescent light bulb,00:21:10
so what are we waiting for? The problem is that00:21:13
such a lamp will be a very short-lived00:21:16
gas that will certainly react with the00:21:18
electrodes, new chemical compounds will be formed00:21:20
and the lamp will fail,00:21:24
which means we need a gas that does not will00:21:27
enter into a chemical reaction as a beggar00:21:30
must be a very lazy gas and such00:21:36
gases and literally yes I am something00:21:41
like that when changing them open one00:21:46
scientist why are we even these are my00:21:52
noble gases00:21:54
[music]00:21:56
phenomenally each gas glows with its own00:22:00
color and that is new words in00:22:04
lighting technology such a lamp hardly heats up and00:22:08
will work much longer than an ordinary00:22:11
incandescent light bulb, all that00:22:13
remains is to build a larger lamp00:22:16
and send it to earth, you can00:22:18
write something, for example, wait a minute, friends, I00:22:22
have a better idea than my00:22:29
colleagues and the benefit of powder,00:22:31
come here I'm observing a00:22:35
very country phenomenon on Mars, I'm talking to Bernard,00:22:52
they're flying small, fly,00:22:59
what, my friend, now your name will go down in00:23:02
history in a completely different light in our00:23:07
world, the discovery of inert or otherwise00:23:09
noble gases00:23:11
belongs to two inert ones, and that is,00:23:13
excuse me, to the most noble English00:23:16
scientist, Lord Roles y xl00:23:18
from Ilya Muromets and for their discovery in00:23:22
1904 they received the Nobel Prize00:23:24
Lord in Physics Acer in Chemistry00:23:29
[music]00:23:35
[music]00:23:55
[music] a00:24:08
fairy tale is an instructive story that a00:24:11
parent tells his child00:24:16
to tell you a fairy tale,00:24:18
well, I don’t know how to tell a fairy tale, just do00:24:28
n’t do it you need such an interface00:24:32
listen to your fairy tale a00:24:37
long time ago in a beautiful minister a bit00:24:42
of green00:24:46
let it be a fairy tale and why am I bringing00:24:54
it there must be stories about00:24:58
him and not in the north it’s cold00:25:03
well a long time ago one00:25:07
kingdom-state film or a handsome00:25:11
prince with the00:25:13
rains and see the poor wandering musician00:25:18
[music]00:25:24
and he immediately in j7 is all a killer00:25:28
[music]00:25:34
and when the musician runs up and whips himself00:25:37
lead to pour00:25:39
you love the song the princess hears the song it’s00:25:44
disgraced and the wandering music or else00:25:47
eggs and live happily ever after and00:25:51
the fairy tale candida and who listened to a very00:25:53
good and all the song and got00:25:59
a princess,00:26:00
but it would have been a big one and a song with such00:26:04
fairy tales, modern youth is completely00:26:06
different overcoming difficulties00:26:09
conflict00:26:10
the hand of the princess still needs to be earned, well,00:26:18
well, but the prince has a spire and an evil stepmother00:26:21
card I don’t want so that everyone is happy00:26:30
just like that,00:26:42
otherwise they get lazy, the princess’s hand still00:26:48
needs to be earned00:26:55
[music]00:27:20
and what happened next the tower is very high,00:27:30
he can’t climb they need a device for00:27:33
voice communication at a distance, which, in other00:27:37
words, is a well-known telephone and the telephone00:27:41
transforms the sound waves of our voice00:27:43
into electrical impulses and transmits these00:27:47
impulses along a copper wire;00:27:51
electrical impulses travel along a wire00:27:54
to another phone and it00:27:55
turns them back into sound waves,00:27:59
so we can hear each other at a very00:28:03
long distance,00:28:04
as far as the wire will reach,00:28:08
the phone is not afraid of even the tallest00:28:11
towers; it will drag the phone from where00:28:14
sand and one I don’t know storyteller you my00:28:18
conservation don’t like the phone00:28:21
come up with your own way well let there00:28:25
be a phone summer wandering musician ca00:28:28
n’t think of anything and then he decided to00:28:31
ask for help and his trumpet is a good00:28:35
wizard00:28:36
[music]00:28:45
and the wizard said my wandering friend I00:28:49
can help you just yesterday I invented00:28:53
one wonderful thing and called it00:28:56
phone00:29:03
[music]00:29:12
yes00:29:14
[applause]00:29:16
[music]00:29:23
princess hear a song and fall in love with a00:29:26
wandering musician they will get married and live00:29:30
long and wait, don’t forget anything oh yes00:29:34
I forgot about the evil sorcerer I’m sure she would00:29:39
I didn’t calmly watch as the princess00:29:41
chatted on the phone with her musicians,00:29:44
she’ll definitely conjure up something else, well,00:29:46
just not a thunderstorm, otherwise everything will be00:29:50
lost, for example, I’m not afraid of thunderstorms,00:30:00
the musician may not be scared,00:30:03
but I’m afraid the telephone connection won’t stand it00:30:07
around the copper wire through which00:30:10
they exchange electric impulses from00:30:11
our phones generate an00:30:13
electromagnetic field; this field is00:30:16
quite easy to record, so00:30:19
someone can eavesdrop on00:30:21
our telephone conversations,00:30:24
but the most unpleasant thing is that these fields are00:30:27
very sensitive to other00:30:29
electrical signals from radio stations00:30:36
[music]00:30:42
electric motors00:30:50
[music]00:30:55
so talk on the phone in a00:30:57
thunderstorm is00:30:58
terribly inconvenient, so let the00:31:02
evil stepmother conjure a thunderstorm00:31:06
[music]00:31:25
and then won’t the princess hear the00:31:29
song of the poor musician? Compression00:31:37
can be transmitted through wires, and only00:31:40
electricity, and light is very simple00:31:45
if you place the light source in a vessel with00:31:49
water or let it out of this vessel, the00:31:52
light will spread along the00:31:54
flowing jets;00:31:55
this is due to the effect of total00:31:58
reflection of light at the water-air interface;00:32:07
this effect is widely used, including in the00:32:10
pharmaceutical industry; and thanks to food, the00:32:14
color can be transferred to the wires;00:32:16
however, these should not be copper wires,00:32:19
but special forces and00:32:20
glass for the ability to transmit00:32:23
a trace they are also called a light beam is00:32:27
reflected from the outer shell and00:32:29
spreads along the light guide in order to00:32:33
transmit sound using light, just00:32:35
connect a microphone to a laser, such a00:32:39
phone will convert the sound of our voice into00:32:42
light pulses and send them along the00:32:44
light guide at the other end of the light guide00:32:47
we will install a photocell00:32:49
that captures light, the telephone00:32:53
converts them back into sound, the00:32:55
interlocutor will hear our voice,00:32:59
thus it is possible to transmit00:33:01
information not with electrical impulses,00:33:04
but with light impulses; such communication cannot be00:33:07
listened to and it is not sensitive to00:33:10
interference00:33:13
[music]00:33:17
in addition, to produce light guides you00:33:21
need to be mute, which is not that much in00:33:23
nature and quartz, that is, ordinary sand and00:33:29
there were fairy tales rubbed by a wizard offensive00:33:35
music new phone with light connection00:33:41
[music]00:33:43
5 Deacon was able to play his song00:33:46
Prince Charming with without any of the toadstools00:33:50
early in00:33:51
the hour to finally hear the song and fall in love with00:33:54
the distributor00:33:56
and the evil card I'm from edges promise00:33:59
[music]00:34:13
I didn’t live happily ever after of course00:34:16
now they deserved it00:34:18
and they always had a wonderful00:34:22
telephone connection00:34:27
[music]00:34:32
baby fairy tale this is an invented story I’ve00:34:36
never actually had anything like this alas00:34:40
unless at some time all00:34:44
the years,00:34:49
glass wires for transmitting light00:34:51
are called optical fibers00:34:54
or fiber optic cables, today they are00:34:57
replacing copper wires all over the world, the00:34:59
importance of this invention was noted by the00:35:02
Nobel Committee in 2009, Charles00:35:06
Ischke received the Nobel Prize in00:35:08
Physics for the development of fiber optic00:35:10
data transmission technology, I don’t00:35:35
understand how it used to be the dogs got acquainted with00:35:38
the princess, well, that’s how the prince found out that the princess was in00:35:42
search, they arranged all kinds of points for the show,00:35:49
so they got acquainted with the show, but it’s practical00:35:56
and without bask00:35:59
without romance00:36:04
[music]00:36:07
I already read this one, too, and this one I read,00:36:20
horses, sorcerers and witches, and00:36:35
this read, the problem of our community is the00:36:41
information vacuum In other words, we are00:36:45
too cut off from the outside world, oh00:36:52
well, but young people don’t have enough00:36:56
air in our company, they need00:37:00
contact, communication with the outside world00:37:26
[music]00:37:44
and I heard someone stopped by on a white horse,00:38:11
what are you doing there, oh, I mean, I also need00:38:15
to explain to you all that I should have hung a sign from the00:38:18
press to take me out of the conclusion who00:38:27
who imprisoned you the right to be honored with a00:38:33
modern princess you have to00:38:35
arrange your happiness with your own00:38:37
hands the main princess needs help which00:38:42
means it will appear soon by the way yes I00:38:47
wanted to read and some of the new things maybe00:38:52
you can go down for a couple minutes00:38:54
I can’t do this, but if you don’t understand, a00:39:00
real prince will00:39:04
definitely find his princess, maybe you want to00:39:25
listen to something new,00:39:29
there’s no time, but if you offered to play, what’s the point, you00:39:31
still win all the time,00:39:34
you’re exactly the same 5 I won,00:39:48
but young people crave communication with their own00:40:02
kind, so maybe it’s time to00:40:05
do something, and by the way, you don’t have anything wrong in the world, there are a00:40:09
lot of interesting things and there are many00:40:12
who want to communicate and exchange00:40:14
information, you just need to figure out how to00:40:17
do it, it’s easy to say in order to00:40:22
exchange information you need at00:40:25
a minimum00:40:26
[music] an00:40:28
electronic computing machine or00:40:30
computer a device designed for00:40:33
processing storage and transmission of information.00:40:35
Currently, computers are capable of00:40:37
analyzing a wide variety of types00:40:39
of information video audio and others00:40:44
[music]00:40:49
we receive the largest amount of data about the world around us through hearing and00:40:52
vision so this is quite enough00:40:56
for touch, smell and taste,00:40:59
only a little bit of information is required, tell me,00:41:09
my friend, you are erudite, what do you think, are there many00:41:12
computers in the world now? I think there are plenty,00:41:16
given global progress,00:41:18
very soon every family will have them,00:41:22
but if we just assume that all00:41:26
these computers are united, friend follow a friend, a global00:41:31
network of computers, I like it,00:41:34
come through and today I understand what00:41:38
computers and communication have to do with it, but even so,00:41:42
you are not civilized, our computers00:41:45
are universal devices for storing and00:41:48
processing any information,00:41:50
text and images, video games, anything,00:41:55
so for example, to see a00:41:57
photograph Cameroonian native we00:42:00
just need to connect our computers00:42:04
the easiest way to connect two00:42:07
cars is to draw a line between them and this00:42:10
reason the computers will exchange00:42:13
information and so the phone I'm afraid we00:42:16
'll have to pull too long a wire00:42:18
to reach the rest of the world00:42:21
Toby we have a phone we couldn't00:42:24
use his company we can00:42:28
use a satellite using00:42:34
radio waves, we can transmit information from00:42:37
one computer to another, but at00:42:39
long distances and due to the attenuation of00:42:41
radio waves and the curvature of the surface of our00:42:43
planet, we have to use an00:42:45
intermediate device that catches the00:42:47
signal, amplifies it and transmits it00:42:50
further to its destination. Such devices00:42:52
are called repeaters, the farther away00:42:56
the transmitter is located and receiver, the00:42:58
more repeaters are required, but if00:43:01
we place the repeater on a satellite00:43:03
located at a very high altitude,00:43:06
more than a hundred kilometers, the00:43:08
coverage area will be almost half of the00:43:11
globe and the signal can be sent to00:43:14
any point using just 100:43:16
repeater, this type of communication is called00:43:19
satellite00:43:21
and everyone should have your number by00:43:28
which it can be identified on the network,00:43:30
just like telephones, for the convenience of00:43:39
communication between computers, each of00:43:41
them is assigned its own number and the00:43:43
internet protocol address, or abbreviated00:43:46
IP address, encrypted, sees the 12-00:43:49
digit year, a unified standard of IP00:43:51
addresses allows you to seamlessly00:43:53
communicate with each other between computers00:43:55
all over the world, you now present us with00:44:00
accessible information from anywhere on the00:44:03
globe, we can travel without00:44:07
leaving the computer,00:44:08
visit museums, go to exhibitions,00:44:11
watch movies and cartoons,00:44:14
and there are white threads here, of course, through a00:44:17
computer network you can order anything00:44:20
you want; a computer network00:44:28
means access to any books00:44:34
these are computer games between players from00:44:38
all over the world this is an opportunity to share00:44:42
their creativity00:44:55

oh without envying this prince whose words00:45:30
the points are much more practical without going yet the00:45:36
prince is the pipe of the country00:45:40
if he stays longer I can00:45:43
grow my hair and he is dependent on stones in00:45:45
my class although this it hurts and what will he00:45:51
discover here, how is it that all this can’t be00:45:57
beautiful among many years in the tower,00:45:59
you don’t go outside to play in the fresh00:46:02
air,00:46:03
not the sun, look at yourself, all00:46:07
pale, your prince will run away as soon as he00:46:11
sees such beauty, let’s bring00:46:14

any more realistic options for finding00:46:20

we will be at home with our heroes00:47:40
[music]00:48:00
[applause]00:48:08
[music] the00:48:20
people of the Don00:48:21
greet their hero we have decided what00:48:26
to do with your planet in order to00:48:28
prove our right to exist the00:48:31
earth must not pass the00:48:33
intelligence test this task we are waiting for the00:48:39
correct answer in a week but good luck00:48:47
[ music]00:48:50
we were given only a week, I hope that with00:48:54
common efforts we can pass this00:48:57
test and save our planet,00:49:01
but what is written there, and to be honest, I have00:49:06
n’t figured it out yet; it’s too small,00:49:11
no, so we won’t see anything, maybe00:49:14
with a microscope, its phenomenal power of the00:49:25
optical microscope is apparently not enough00:49:28
the symbols are too small in an optical00:49:31
microscope,00:49:32
two main elements are the lens and the eyepiece,00:49:36
their lens collects visible light passed00:49:39
through or reflected from the object and creates its00:49:42
image. Thanks to the microscope, we00:49:44
can see what is inaccessible to the00:49:46
naked eye, but its capabilities are00:49:48
not unlimited; the00:49:49
magnification limit of an optical microscope is00:49:51
2000 times00:49:53
I can’t see what’s written here,00:49:58
great joke, buddy, I almost did00:50:02
n’t believe in it, even children, why don’t00:50:05
you believe on the planet,00:50:08
well, not at all, let me00:50:11
sleep a little more and I’ll believe in00:50:17
anything, let’s do better and better, but this00:50:32
is not a game this is a question of the future of our00:50:35
planet and the closest00:50:39
colleague admit so that the joke does not00:50:43
succeed00:50:46
[music]00:50:58
the capabilities of the microscope will not be00:51:00
enough I will not be too small00:51:12
let's not beat around the bush00:51:15
let's think productively come on so00:51:20
why are you saying the possibility and the00:51:22
microscope is not enough the light is00:51:26
spreading electromagnetic00:51:28
waves of visible light minimum00:51:30
distance between waves00:51:31
or in other words wavelength 38000:51:34
nanometers we see light reflected from00:51:36
an object but in order for light to00:51:38
be reflected the size of the object must be00:51:40
larger than long waves00:51:42
if the object is too small then the waves will00:51:44
simply pass through it and we will not00:51:46
see it why not take00:51:49
radiation with a shorter wavelength, but00:51:52
you still can’t catch the00:51:55
eye’s capabilities, so you need to project this00:51:58
radiation onto a screen on which you00:52:00
can see it, my nice friend00:52:06
[music]00:52:08
my friends, I00:52:10
proudly present to your attention00:52:13
the latest achievement of the genius of earthlings,00:52:16
electronic a microscope,00:52:21
unlike an optical microscope, an electron00:52:23
microscope does not use visible light, but a00:52:25
beam of electrons, hot tungsten00:52:28
emits a beam of electrons, just like the rays of00:52:31
light in an optical microscope, a beam of00:52:33
electrons is focused by special00:52:35
electromagnetic lenses, electrons00:52:38
fly through the sample and create an00:52:40
enlarged image of it on the screen, although it is00:52:43
black and white, but this is not it is so important for00:52:45
science00:52:46
due to the fact that an electron00:52:48
microscope uses a beam of electrons00:52:50
and not ordinary light, it allows you to see00:52:53
objects a thousand times smaller text that00:52:55
can be examined with an optical microscope00:52:59
now finally we can read what is00:53:02
written in this task anyway we ca00:53:14
n’t make out anything in00:53:16
the image even smaller than I thought, it is00:53:19
literally made up of nanoparticles00:53:22
on earth, there are simply no such technologies, it’s00:53:26
impossible, moose friend, but you can’t behave00:53:30
like that, husband, when you were sleeping after, I can’t even00:53:34
read this unfortunate task,00:53:37
3 days left, the earth is doomed,00:53:40
I’m mediocrity, you’re not mediocrity,00:53:45
you created such a thing a wonderful device, I00:53:48
thereby rendered an invaluable service00:53:50
to the planet, maybe you shouldn’t save it anymore,00:53:52
let others take care of this, come on,00:53:57
you need to calm down all your fears as if00:54:07
by hand00:54:08
[music]00:54:25
very00:55:28
where am I, what happened, I’m blind, I know what00:55:43
needs to be done if we don’t have enough00:55:45
vigilance to what - to see, we00:55:47
can always feel it, in this case00:55:51
our capabilities are limited by the size of00:55:54
the hooves, that is, the smaller our00:55:56
hooves are, the finer details we can feel with00:56:00
them; the capabilities of the electron00:56:03
microscope are amazing, but there are things00:56:05
that even he cannot see, for00:56:07
example, he is, alas,00:56:09
sometimes useless when working with nano00:56:11
objects, but if we cannot see something, we00:56:14
can try it by touch;00:56:16
however, to feel individual00:56:18
nanoparticles, you will need a needle on, but00:56:20
rather, which will be one or more00:56:22
atoms; such a needle can be made00:56:25
of silicon if you move it along the00:56:28
surface will react to00:56:30
nanoparticles vibration of the needle reads the00:56:32
laser as a result we can build a00:56:34
volumetric relief of the surface we study in the00:56:36
sample and we will finally be able to see00:56:39
nanoparticles00:56:46
[music]00:56:54

you more confident in your answer than00:57:53
and this is the correct answer00:57:57

satellite navigation a00:59:34
very useful and smart invention of something00:59:38
not useful just comes to hand before00:59:41
it appears I had to navigate00:59:44
straight away old-fashioned methods one day00:59:51

[music]01:00:23
badge listens to reception after reception as he did the01:00:27
ice test and pass normally,01:00:30
finally I’m now flying over the desert01:00:34
here is a little sawy and the compass01:00:39
will be spoiled I don’t quite know the idea of01:00:42
being honda01:00:44
how to understand you you are lost a little01:00:50
lost01:01:07
[music] I’m01:01:12
afraid my caring friend01:01:15
your efforts may not be enough the desert is01:01:18
too big and we don’t even01:01:20
know approximately where our pin may be all is the same01:01:24
as looking for food01:01:25
[music]01:01:36
well, of course, my friend, the resourceful01:01:40
inversion method needs to solve the problem on the contrary, the01:01:45
inversion method01:01:46
or reverse analogy means doing01:01:49
something in reverse, in other words,01:01:51
turning it upside down, in other words, it is01:01:54
much easier to prevent the pin opera from01:01:57
finding us, or quite simply put the01:02:00
species needs to decide for itself the01:02:03
right direction in order to get01:02:05
out of the desert to the already desert without a body,01:02:13
this is not easy to do, but before,01:02:16
travelers somehow managed to01:02:18
find the right road, the direction to the01:02:22
sides of the horizon are interconnected01:02:25
if at least one of them is known, you can01:02:28
determine the rest doc01:02:31
if suddenly you have lost your orientation on the01:02:33
terrain the role of the compass and the sun can play01:02:36
in the northern hemisphere in the morning the sun01:02:40
rises in the east at noon it is exactly in the01:02:43
south and in the evening it sets in the west that’s01:02:50
bad luck01:02:51
however at night we always have one minute at our disposal there is oh there is the01:02:56
polar star the polar01:03:03
star is on in the north it can be01:03:06
found by the constellation Ursa Minor,01:03:08
it is located at the very end of its tail,01:03:12
but if the sky is suddenly clouded and01:03:15
you can’t see the sun or stars,01:03:19
you can determine the direction by surrounding01:03:21
objects, for example, moss or deprived of01:03:23
stones, stumps, tree trunks01:03:26
on the northern side of the city of Revi in the northern01:03:29
side is usually rougher and darker than the01:03:31
southern anthill is usually located to the south01:03:34
of the nearest trees, while the southern01:03:36
side of the anthill is flatter than the01:03:39
northern01:03:48
contour contour this base I have good news for you01:03:52
if there is no question you can always01:03:55
navigate by the stars or the01:03:57
anthill I have no stars anthills and there’s01:04:04
nothing to them,01:04:08
just a landmark, just sand, well, there must be a way to01:04:15
get out, some old01:04:18
proven way01:04:21
[applause]01:04:24
baby,01:04:25
we’ve had enough of the old-fashioned methods of01:04:28
determining our coordinates, we01:04:30
can use space satellites;01:04:36
satellite navigation determines the01:04:38
position of an object with an accuracy of 1001:04:41
meters in some cases01:04:43
accuracy can reach up to three meters,01:04:45
while it is possible to determine not only01:04:47
latitude and longitude01:04:49
but also altitude above sea level; satellite01:04:53
navigation includes three segments; a01:04:56
space group of twenty-four01:04:58
satellites and several spare ones; a01:05:00
control system for tracking01:05:03
satellites that determines their exact01:05:05
position relative to the earth and01:05:08
user receiver measuring the01:05:10
distance to satellites 24 working01:05:15
satellites01:05:16
are located at an altitude of about01:05:18
20 thousand kilometers and are divided into 6 groups01:05:21
of 4 satellites; a01:05:23
group of four satellites rotates in01:05:26
one orbit, dividing into equal parts and01:05:28
making one revolution around the earth in 1201:05:31
hours; this system of satellite movement01:05:34
leads to because at01:05:37
least four satellites are always visible from every point on the planet,01:05:39
in order to determine its01:05:42
position the01:05:43
user’s receiver must determine the01:05:45
distance to three visible satellites,01:05:47
let the distance to one of the satellites01:05:50
be x kilometers, then the receiver01:05:53
must be on an imaginary01:05:55
green sphere centered at the01:05:57
satellite’s location and radius x,01:06:00
if the receiver measures the distance to the01:06:02
second satellite and builds the01:06:04
corresponding sphere,01:06:06
then the position of the receiver will be at one of01:06:09
the points where these two spheres intersect, the01:06:11
two spheres intersect in a circle, for01:06:15
clarity, let’s denote it in red, calculating the01:06:18
distance to 3, calmly01:06:20
the receiver builds the third sphere and01:06:23
determines two points goes to and the section with the01:06:25
red circle01:06:27
