Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:01:06,160 --> 00:01:11,481
You know, in physics we believe that everything
around us can be made comprehensible.
2
00:01:13,140 --> 00:01:16,380
It's a job that can easily set you apart
from other people.
3
00:01:17,080 --> 00:01:18,520
There is no restriction on thought.
4
00:01:25,330 --> 00:01:29,170
I think I have a quite pictorial view of
physics.
5
00:01:30,190 --> 00:01:31,650
For me, particles are colourful.
6
00:01:31,651 --> 00:01:33,070
For me an electron is red.
7
00:01:33,290 --> 00:01:33,670
I don't know why.
8
00:01:33,770 --> 00:01:34,350
Don't ask me why.
9
00:01:34,690 --> 00:01:35,950
An electron is red.
10
00:01:36,310 --> 00:01:38,230
A photon of course is yellow because of
light.
11
00:01:38,850 --> 00:01:40,330
A proton is brown.
12
00:01:40,990 --> 00:01:44,970
My perception on reality, you know,
I go deep inside, so I eat my spaghetti
13
00:01:44,971 --> 00:01:47,290
and I think of the quarks that are inside
the spaghetti.
14
00:01:47,650 --> 00:01:48,650
It's true.
15
00:01:49,450 --> 00:01:50,650
You will say I'm crazy.
16
00:01:52,410 --> 00:01:56,170
I am a physicist, but I love music and
I've been studying music.
17
00:01:57,270 --> 00:02:01,670
Music and physics are part of the same
thing, you know, human curiosity,
18
00:02:01,930 --> 00:02:07,179
human creativity, the wish
of exploring or understanding
19
00:02:07,180 --> 00:02:10,590
how things work at the
most fundamental level.
20
00:02:11,070 --> 00:02:14,730
And what really touches
me in science, like in
21
00:02:14,731 --> 00:02:18,630
music, is this complexity
built upon simplicity.
22
00:02:21,070 --> 00:02:26,850
In music you have very complex and rich
symphonies, think about Beethoven,
23
00:02:27,330 --> 00:02:32,430
Mahler, but actually they are built upon
the combination of seven notes and
24
00:02:32,431 --> 00:02:36,935
likewise nature is beautiful and
extremely complex, but actually
25
00:02:36,936 --> 00:02:41,330
the most fundamental level
is made of just three particles.
26
00:02:47,780 --> 00:02:48,780
I
27
00:02:52,020 --> 00:02:56,200
always wanted to understand what are we
made out of.
28
00:02:56,900 --> 00:03:02,160
I need to know how are things connected,
how does one depend on the other.
29
00:03:11,390 --> 00:03:19,825
It is the most powerful, most
complex machine ever built
30
00:03:19,826 --> 00:03:27,270
by mankind to try to understand
why we can exist at all.
31
00:03:32,410 --> 00:03:33,570
When
32
00:04:02,580 --> 00:04:07,840
I was young I wanted to understand the
logic of nature,
33
00:04:12,150 --> 00:04:17,350
the fundamental laws which allows us to
exist.
34
00:04:20,190 --> 00:04:24,530
We need these laws for our existence.
35
00:04:25,670 --> 00:04:32,030
The trouble is that these laws can be used
for peace and for war.
36
00:04:38,600 --> 00:04:41,560
Now I am the coming death, the
destruction.
37
00:04:45,260 --> 00:04:52,440
Dr. Oppenheimer, you and many like you who
brought the bomb into being still seem to
38
00:04:52,441 --> 00:04:56,180
suffer, may I say, from a bad conscience
about it.
39
00:04:56,500 --> 00:04:57,500
Is that true sir?
40
00:04:58,580 --> 00:05:05,900
I do think it has left a mark on many of
those who were responsibly engaged.
41
00:05:06,700 --> 00:05:10,260
This is not the natural business of a
scientist.
42
00:05:12,120 --> 00:05:19,760
After the first few minutes of elation,
I realized what had happened to the world.
43
00:05:20,560 --> 00:05:23,940
The big thing I felt was to eliminate
this.
44
00:05:24,800 --> 00:05:32,680
We have to explain to the governments that
what we want to do is never to be
45
00:05:32,681 --> 00:05:38,280
associated with the use of these laws for
war.
46
00:05:47,630 --> 00:05:52,005
Today CERN is a truly global
laboratory with a community of
47
00:05:52,006 --> 00:05:57,410
more than 17,000 people
across more than 110 nationalities.
48
00:05:57,590 --> 00:06:02,650
An incredible melting pot of languages,
cultures, traditions.
49
00:06:04,250 --> 00:06:11,170
But in a world where conflicts between
countries, religions and cultures sadly
50
00:06:11,171 --> 00:06:18,010
persist, this is a truly precious gift
which cannot be taken for granted.
51
00:06:20,010 --> 00:06:23,107
We now have autocrats
ruling the largest nations
52
00:06:23,108 --> 00:06:26,110
on earth in ways we
thought belonged to history.
53
00:06:26,450 --> 00:06:30,730
Russia launched a full scale invasion of
Ukraine by land, air and... CERN has
54
00:06:30,731 --> 00:06:34,266
announced that it will
end cooperation with up
55
00:06:34,267 --> 00:06:37,571
to 500 scientists from
Russian institutions.
56
00:06:41,690 --> 00:06:46,382
The last world war had
been so terrible, I thought it
57
00:06:46,383 --> 00:06:49,990
would be unimaginable that
a new war would start again.
58
00:06:50,770 --> 00:06:52,590
Humanity should have learned a lesson.
59
00:06:53,810 --> 00:07:00,090
Here at CERN, several thousand scientists
coming from different social, political
60
00:07:00,091 --> 00:07:04,670
systems, having different religions,
having completely different mentalities,
61
00:07:05,150 --> 00:07:09,870
work together very peacefully and,
I might say so, also very successfully.
62
00:07:14,860 --> 00:07:19,180
How many years ago was it that you stepped
down as director-general?
63
00:07:19,400 --> 00:07:21,300
It's a long time ago, 1990.
64
00:07:22,880 --> 00:07:24,560
And you're still coming in?
65
00:07:26,280 --> 00:07:31,820
When I became 100 years old, some people
asked me, what do you do to become so old?
66
00:07:32,660 --> 00:07:33,820
I said, there are two things.
67
00:07:34,740 --> 00:07:38,240
Always stay active and always be curious.
68
00:07:42,000 --> 00:07:44,301
The CERN Council
decided that we have to stop
69
00:07:44,302 --> 00:07:47,761
almost all collaborations
with Russia now.
70
00:07:48,340 --> 00:07:49,340
It's a pity.
71
00:07:50,000 --> 00:07:53,883
I think it was more or less
the first time that in the 70 years
72
00:07:53,884 --> 00:07:57,840
of CERN that politics determined
essentially a council decision.
73
00:08:08,040 --> 00:08:10,420
So this week there was Council Week at
CERN.
74
00:08:11,160 --> 00:08:13,906
So it means the
representative of our member
75
00:08:13,907 --> 00:08:16,961
states got together for
decisions and discussions.
76
00:08:17,800 --> 00:08:22,960
The contracts with Belarus and with Russia
already have been suspended.
77
00:08:23,660 --> 00:08:29,160
However, there's still this laboratory in
Russia, which is a bit similar to what we
78
00:08:29,161 --> 00:08:33,720
have at CERN, and the collaboration with
them dates back to 1967.
79
00:08:34,360 --> 00:08:37,860
So it's a really long-standing partner.
80
00:08:38,720 --> 00:08:40,780
Here at CERN we have
Israelis working together
81
00:08:40,781 --> 00:08:43,441
with Palestinians,
Indians with Pakistanis.
82
00:08:43,740 --> 00:08:50,360
So science and fundamental science gives
you a kind of basis where people,
83
00:08:50,980 --> 00:08:54,480
independent of their religion,
independent of their political system
84
00:08:54,481 --> 00:08:57,960
where they grew up in, can collaborate and
can communicate.
85
00:08:58,080 --> 00:09:00,300
And I think that's something important to
keep.
86
00:09:00,620 --> 00:09:03,220
That was what CERN is for, science for
peace.
87
00:09:08,760 --> 00:09:15,192
I remember when I first came
to CERN I was here visiting
88
00:09:15,193 --> 00:09:19,120
because I was thinking about
moving here and I wasn't sure.
89
00:09:20,700 --> 00:09:27,220
One of my mentors at the university
arranged to see the Atlas detector and it
90
00:09:27,221 --> 00:09:32,740
was the best thing anyone ever did for me
because when you see it, it was like,
91
00:09:33,400 --> 00:09:34,400
it was love.
92
00:09:36,820 --> 00:09:37,820
You
93
00:09:47,020 --> 00:09:54,360
know, it's just this beautiful detector
with the precision of it, the size of it,
94
00:09:54,760 --> 00:09:58,807
the amount of human
effort and passion that
95
00:09:58,808 --> 00:10:02,641
went into building
every single little part.
96
00:10:03,000 --> 00:10:04,400
I just wanted to be a part of that.
97
00:10:06,500 --> 00:10:08,440
I got to build this, help build this.
98
00:10:08,620 --> 00:10:11,960
There are, you know, thousands of people
involved in this construction and I really
99
00:10:11,961 --> 00:10:14,540
got to help with those teams putting it
all together.
100
00:10:15,760 --> 00:10:17,800
There was a common goal that we all had.
101
00:10:17,880 --> 00:10:20,560
So it gave a special spirit to the whole
thing.
102
00:10:21,040 --> 00:10:26,260
There was this chance to unlock something
very deep about nature itself.
103
00:10:32,490 --> 00:10:35,465
2008, it was really the
first time we switched
104
00:10:35,466 --> 00:10:37,970
on our camera Atlas
and took the first data.
105
00:10:38,430 --> 00:10:43,150
But the room was crowded at that time, so
everybody who contributed was in that room.
106
00:10:43,750 --> 00:10:46,670
The preparation of this experiment took
decades.
107
00:10:52,930 --> 00:10:57,730
We now believe that all the matter that we
now see in the universe was made during
108
00:10:57,731 --> 00:11:00,177
the first fraction of a
fraction of a fraction
109
00:11:00,178 --> 00:11:02,991
of a second of the
age of the universe.
110
00:11:03,090 --> 00:11:07,910
In fact, it's something like 10 to the
minus 35 seconds.
111
00:11:08,670 --> 00:11:14,410
That means a one with 34 zeros before it.
112
00:11:14,830 --> 00:11:15,830
Extremely small time.
113
00:11:17,750 --> 00:11:22,850
There's zero particles and all the other
elementary particles have masses.
114
00:11:23,210 --> 00:11:24,210
They weigh something.
115
00:11:24,670 --> 00:11:25,670
Why is that?
116
00:11:26,470 --> 00:11:31,510
We believe that comes about from a
particle called the Higgs boson.
117
00:11:32,490 --> 00:11:37,210
Peter Higgs proposed the existence of the
Higgs boson in 1964.
118
00:11:37,810 --> 00:11:40,930
I would compare it to a Roman arch.
119
00:11:41,690 --> 00:11:47,350
So you've got this beautiful semicircular
arch and at the top there is a capstone.
120
00:11:48,070 --> 00:11:51,530
And if that capstone were not there,
the arch would collapse.
121
00:11:52,710 --> 00:11:57,570
With my colleagues, we basically sat down
and said, OK, we don't know what the mass
122
00:11:57,571 --> 00:12:03,250
of the Higgs boson might be, but for
different masses we could figure out the
123
00:12:03,251 --> 00:12:05,190
way in which it would show up in an
experiment.
124
00:12:05,910 --> 00:12:08,130
Some experiments of that type were being
done as so.
125
00:12:08,870 --> 00:12:12,456
But we really thought it
was going to be heavier and
126
00:12:12,457 --> 00:12:15,230
could only be found at a
higher energy accelerator.
127
00:12:20,280 --> 00:12:22,660
The protons are in the machine.
128
00:12:25,800 --> 00:12:27,600
We are ready at this end.
129
00:12:31,350 --> 00:12:32,570
We are now in the countdown.
130
00:12:49,310 --> 00:12:52,430
So what happens in the sort of experiments
that are done here, well actually sort of
131
00:12:52,431 --> 00:12:57,459
underground in some sense,
what's being done down there is
132
00:12:57,460 --> 00:13:00,451
a sort of recreation of the
first seconds of the Big Bang.
133
00:13:08,020 --> 00:13:14,320
You are about 100 metres underground at
the absolute best experiment on Earth.
134
00:13:15,760 --> 00:13:22,280
The LHC pipe runs through the centre and
protons come in from either direction.
135
00:13:22,440 --> 00:13:26,660
If we are lucky and if they hit really
like a big strong head-on collision,
136
00:13:27,320 --> 00:13:29,311
we can create all
sorts of cool stuff,
137
00:13:29,312 --> 00:13:32,921
potentially something we
have never seen before.
138
00:13:36,810 --> 00:13:41,210
It's very nice here in the control room
because you can see in real time all these
139
00:13:41,211 --> 00:13:46,930
collisions and the particles, the shower
coming out of it and sometimes it's really
140
00:13:46,931 --> 00:13:53,030
overwhelming and actually it's also
bothering me thinking about all the things
141
00:13:53,031 --> 00:13:57,010
that they will discover in the future and
that maybe I will never know.
142
00:14:01,130 --> 00:14:04,190
Everybody is trying to write his history
in a way.
143
00:14:04,430 --> 00:14:05,430
It's our ambition.
144
00:14:06,310 --> 00:14:11,970
The man of the caverns was writing
pictures of cows on the walls, right?
145
00:14:12,670 --> 00:14:14,717
So that 3,000 years
later you walk in there,
146
00:14:14,718 --> 00:14:17,451
he says, my God, there's
a human being there.
147
00:14:18,150 --> 00:14:23,030
We are not painting ghosts on walls or
caves.
148
00:14:23,670 --> 00:14:26,110
We are trying to do much more
sophisticated things.
149
00:14:27,110 --> 00:14:29,265
When it's all done and
over, what do you think
150
00:14:29,266 --> 00:14:32,331
20th century civilization
have left behind?
151
00:14:32,930 --> 00:14:37,416
My own opinion is that we
care and we respect us and we
152
00:14:37,417 --> 00:14:40,330
respect us on the basis of
the understanding we have.
153
00:14:55,820 --> 00:15:02,040
When I arrived here at CERN, I was this
student, very much lacking in confidence,
154
00:15:02,810 --> 00:15:08,240
looking around at what's happening here,
and I did not feel that I fit in here.
155
00:15:08,820 --> 00:15:10,280
I felt like an imposter.
156
00:15:11,260 --> 00:15:14,374
It was like another
planet, first of all, because
157
00:15:14,375 --> 00:15:17,520
there were literally no
Indians here at CERN.
158
00:15:18,700 --> 00:15:20,000
It was incredible.
159
00:15:20,280 --> 00:15:24,080
I can tell you that even the smell of
coffee was alien to me.
160
00:15:26,840 --> 00:15:33,300
Coming from India, a woman working in the
laboratory, you know, with Europeans and
161
00:15:33,301 --> 00:15:35,940
with Americans and all that, it was not
easy.
162
00:15:36,620 --> 00:15:39,482
The confidence is today,
the smiles are today, but
163
00:15:39,483 --> 00:15:43,860
I have had endless
sleepless nights, years on end.
164
00:15:52,520 --> 00:15:55,760
This human endeavor is mind-boggling.
165
00:16:11,220 --> 00:16:14,948
When you were presented
with the plans for the LHC,
166
00:16:14,949 --> 00:16:18,860
the engineering challenge
is absolutely enormous.
167
00:16:19,420 --> 00:16:22,050
Well, I wasn't presented with the plans,
I made the plans.
168
00:16:26,960 --> 00:16:29,200
I came to CERN in 69.
169
00:16:31,500 --> 00:16:32,500
Anti-product now.
170
00:16:33,420 --> 00:16:35,020
What is it, 55 years now?
171
00:16:35,600 --> 00:16:36,600
Practically.
172
00:16:38,240 --> 00:16:39,520
55 of the 70.
173
00:16:41,400 --> 00:16:44,140
But this is home now, after all this time.
174
00:16:45,080 --> 00:16:47,721
I took over the project
in 93, prepared for
175
00:16:47,722 --> 00:16:51,700
approval, took until the
end of 1994 to get approved.
176
00:16:58,210 --> 00:17:01,150
The project could provide answers to the
nature of the universe.
177
00:17:01,830 --> 00:17:04,924
The machine, called the
Large Hadron Collider, will aim
178
00:17:04,925 --> 00:17:07,750
to recreate the conditions
at the time of the Big Bang.
179
00:17:09,730 --> 00:17:13,470
The tunnel was there already, we took it
over from the previous machine.
180
00:17:15,970 --> 00:17:22,530
There is a pit where the big magnets can
be lowered into the tunnel, onto a
181
00:17:22,531 --> 00:17:26,150
transport vehicle, and then that gives us
access to the LHC ring.
182
00:17:33,590 --> 00:17:39,751
This is really the biggest and most
complex scientific project ever undertaken.
183
00:17:40,410 --> 00:17:43,145
The whole 27-kilometer
circumference is
184
00:17:43,146 --> 00:17:46,731
aligned to better than
a tenth of a millimeter.
185
00:17:47,650 --> 00:17:52,470
Very, very, very tiny movements will
affect our data.
186
00:17:53,390 --> 00:17:57,870
The moon, for example, also affects the
LHC.
187
00:18:04,770 --> 00:18:09,810
It's the kind of breathing that goes on,
like the tides, you know.
188
00:18:11,330 --> 00:18:13,570
And we need to track everything.
189
00:18:14,030 --> 00:18:20,810
Think of gravity, that every time there is
a movement of a piece of matter around the
190
00:18:20,811 --> 00:18:26,730
Earth, that actually translates into a
very, very, very tiny movement,
191
00:18:27,130 --> 00:18:30,092
which can be reflected in
the measurements at the
192
00:18:30,093 --> 00:18:32,431
scale at which we do the
measurements, you know.
193
00:18:32,630 --> 00:18:34,730
We are looking for
a particle that has a
194
00:18:34,731 --> 00:18:38,211
lifetime of ten to the
minus twenty-two seconds.
195
00:18:39,730 --> 00:18:43,910
And within that, if there is a movement,
you're lost.
196
00:18:48,330 --> 00:18:53,190
So the idea behind the collision is you're
just getting a huge amount of energy into,
197
00:18:53,490 --> 00:18:57,330
you know, a single spot, and then you can
produce something very massive.
198
00:18:58,290 --> 00:19:02,890
And so by studying these collisions,
we understand this very microscopic world,
199
00:19:03,330 --> 00:19:09,050
and then that helps us understand how we
evolved from a microscopic world to the
200
00:19:09,051 --> 00:19:12,910
macroscopic to galaxies, superclusters of
galaxies.
201
00:19:13,150 --> 00:19:14,610
It's all intertwined.
202
00:19:15,130 --> 00:19:17,450
We can't understand that without
understanding this.
203
00:19:49,320 --> 00:19:50,320
Hello.
204
00:19:50,780 --> 00:19:51,780
Welcome.
205
00:19:51,980 --> 00:19:52,980
Hello.
206
00:19:53,540 --> 00:19:56,560
Well, it's nice to welcome you here in my
home.
207
00:19:57,080 --> 00:19:58,080
Please come in.
208
00:19:58,420 --> 00:19:59,420
Thank you very much.
209
00:20:00,960 --> 00:20:05,040
Do you still play the piano?
210
00:20:05,041 --> 00:20:07,160
Yes, a little bit, yes, a little bit.
211
00:20:07,720 --> 00:20:10,380
I like music besides physics very much.
212
00:20:19,470 --> 00:20:21,510
I am a very old man now.
213
00:20:21,810 --> 00:20:24,719
I have the advantage
that I've seen now
214
00:20:24,720 --> 00:20:28,751
practically hundred
years of European history.
215
00:20:29,070 --> 00:20:31,490
During the last war, I was a soldier.
216
00:20:31,850 --> 00:20:34,770
I was fighting against Russia and the
British.
217
00:20:42,450 --> 00:20:46,910
In fact, I was, by chance, also a Dresden
when it was bombed.
218
00:20:47,410 --> 00:20:47,990
So I've seen it.
219
00:20:48,050 --> 00:20:49,150
Fortunately, I survived.
220
00:20:52,880 --> 00:20:59,241
So I know what real war means, where
10,000 people were killed in one night.
221
00:21:00,900 --> 00:21:02,880
All that, of course, is nightmare.
222
00:21:06,160 --> 00:21:10,780
When war was ended, I was taken prisoner
by British troops near Hamburg.
223
00:21:11,500 --> 00:21:15,340
At that time, I imagine there was
practically no radio.
224
00:21:15,860 --> 00:21:18,240
There were just a few local newspapers.
225
00:21:19,060 --> 00:21:20,620
There was no television nothing.
226
00:21:21,200 --> 00:21:25,720
So I learned about the bombs rather late,
more or less by chance.
227
00:21:41,650 --> 00:21:43,490
It is an atomic bomb.
228
00:21:44,990 --> 00:21:48,330
It is a harnessing of the basic power of
the universe.
229
00:22:27,730 --> 00:22:33,511
I knew many of the people who were
involved in the development of these bombs.
230
00:22:36,900 --> 00:22:38,920
In Germany, it was Heisenberg.
231
00:22:44,740 --> 00:22:49,500
And it was never quite clear whether the
nuclear chain reaction would work.
232
00:22:50,380 --> 00:22:51,980
I knew Heisenberg quite well.
233
00:22:52,580 --> 00:22:56,797
He was surprised that the
bomb had worked because he had
234
00:22:56,798 --> 00:23:00,560
calculated the detailed
cross-section and he made a mistake.
235
00:23:00,561 --> 00:23:05,940
It was incredible because Heisenberg said,
Look, it can't have worked.
236
00:23:06,600 --> 00:23:07,980
And I told him yes, but it worked.
237
00:23:08,080 --> 00:23:11,460
So he sat down and found out, yes,
he had made a mistake.
238
00:23:16,090 --> 00:23:21,932
A short time ago, an American
airplane dropped one bomb
239
00:23:21,933 --> 00:23:25,430
on Hiroshima and destroyed
its usefulness to the enemy.
240
00:23:26,410 --> 00:23:30,870
That bomb has more power than 20,000 tons
of TNT.
241
00:23:32,250 --> 00:23:35,879
The force from which the
sun draws its power has been
242
00:23:35,880 --> 00:23:39,990
loosed against those who
brought war to the Far East.
243
00:23:41,090 --> 00:23:44,152
We have spent more
than 2 billion dollars on
244
00:23:44,153 --> 00:23:47,711
the greatest scientific
gamble in history.
245
00:23:47,890 --> 00:23:49,010
And we have won.
246
00:23:54,960 --> 00:24:01,581
What has been done is the greatest
achievement of organized science in history.
247
00:24:10,780 --> 00:24:18,940
I think when you play a meaningful part in
bringing about the death of over 100,000
248
00:24:18,941 --> 00:24:24,201
people and the injury
of a comparable number,
249
00:24:24,202 --> 00:24:31,160
you naturally don't
think of that as with ease.
250
00:24:31,740 --> 00:24:33,580
We had known the sin of pride.
251
00:24:34,300 --> 00:24:38,660
We had turned to effect in what was to
come.
252
00:24:38,661 --> 00:24:43,040
It proved to be a major way, the course of
man's history.
253
00:24:54,720 --> 00:24:57,795
The European Union, for
nuclear physics, has fixed
254
00:24:57,796 --> 00:25:00,621
the size of 100
international research atoms.
255
00:25:02,320 --> 00:25:04,504
The delegates brought
their lives on Geneva,
256
00:25:04,505 --> 00:25:07,381
to the great satisfaction
of the president.
257
00:25:11,520 --> 00:25:16,560
It is an idea which is, to some extent,
unimaginable today.
258
00:25:16,561 --> 00:25:24,100
Shortly after the Second World War,
a handful of visionary scientists and a
259
00:25:24,101 --> 00:25:33,040
handful of visionary diplomats getting
together from all continents and saying,
260
00:25:33,300 --> 00:25:37,960
okay, we have to do something to get
Europe out of the ruins.
261
00:25:38,820 --> 00:25:41,760
It took only a few years to create CERN.
262
00:25:43,100 --> 00:25:44,660
This is amazing.
263
00:25:44,661 --> 00:25:47,480
I cannot imagine something like this
today.
264
00:25:52,790 --> 00:25:56,930
The Council of CERN is made up of
delegates from the 13 member states.
265
00:25:58,390 --> 00:26:02,670
The purpose of the European Organization
for Nuclear Research is to further
266
00:26:02,671 --> 00:26:06,950
collaboration in scientific research of a
purely fundamental nature.
267
00:26:09,130 --> 00:26:12,150
A few years ago, the Council of CERN was
celebrated by Mr. Dumont.
268
00:26:13,810 --> 00:26:19,670
And here, in Denmark, in 1972,
Robert Oppenheimer, creator of the Bomba,
269
00:26:22,150 --> 00:26:24,550
Heisenberg, almighty, in 1972.
270
00:26:26,770 --> 00:26:33,450
Looking at these people together,
Oppenheimer, Heisenberg, who worked
271
00:26:33,451 --> 00:26:40,170
beforehand on different sites within the
war, but they ignored the political
272
00:26:40,171 --> 00:26:43,830
difference and they were just
concentrating on science.
273
00:26:47,870 --> 00:26:56,370
An atomic war would end this civilization
and would end any science and so on.
274
00:26:58,230 --> 00:27:02,395
Mankind has to learn to
control itself because it now
275
00:27:02,396 --> 00:27:06,550
has, within its power, to
destroy itself very cheaply.
276
00:27:11,030 --> 00:27:15,551
We brought the people
together, we wrote a convention
277
00:27:15,552 --> 00:27:19,670
which clearly states
peaceful application only.
278
00:27:27,250 --> 00:27:32,250
The organization should provide for
collaboration among European states in
279
00:27:32,251 --> 00:27:36,590
nuclear research of a pure scientific and
fundamental character.
280
00:27:41,460 --> 00:27:48,440
When we work, we don't think of making
military applications.
281
00:27:51,380 --> 00:27:54,904
The responsibility of
the scientists is that
282
00:27:54,905 --> 00:27:58,841
the new technologies
are used in the proper way.
283
00:27:59,440 --> 00:28:05,880
Every technology can be used for the good
of humanity or against humanity.
284
00:28:06,460 --> 00:28:11,480
A typewriter can be used for war or can be
used for peaceful poetry.
285
00:28:25,530 --> 00:28:29,490
I grew up in an industrial part of the
United States in western Pennsylvania
286
00:28:29,491 --> 00:28:33,310
where everybody's grandfather and father
worked in the steel mills.
287
00:28:34,170 --> 00:28:36,549
And they told us when we
were kids that if we didn't
288
00:28:36,550 --> 00:28:39,190
study hard, we'd end up
in the factory like they were.
289
00:28:39,750 --> 00:28:41,810
And I totally failed, you can see.
290
00:28:51,610 --> 00:29:00,150
We have Metallica, Muse, Roger Waters,
Jack White, Pixies.
291
00:29:00,151 --> 00:29:02,090
The bar is pretty high.
292
00:29:02,250 --> 00:29:04,030
It's not just for any rock stars.
293
00:29:05,390 --> 00:29:06,590
There'll be more, I hope.
294
00:29:09,050 --> 00:29:12,999
The science fiction question
is do we have enough
295
00:29:13,000 --> 00:29:16,430
antimatter to be dangerous
or to power a starship?
296
00:29:17,330 --> 00:29:20,823
And the answer is even
though this is the best and only
297
00:29:20,824 --> 00:29:24,730
machine to create this
anti-hydrogen atom, we kind of suck.
298
00:29:25,210 --> 00:29:27,870
It's never going to be a danger to
anybody.
299
00:29:27,871 --> 00:29:32,630
It would take longer than
the age of the universe
300
00:29:32,631 --> 00:29:36,511
to accumulate just
one gram of antimatter.
301
00:29:36,710 --> 00:29:40,070
But that one gram of antimatter could put
a space shuttle into orbit.
302
00:29:40,710 --> 00:29:44,910
That's a cataclysmic amount of antimatter
to lose all at once.
303
00:29:45,450 --> 00:29:48,891
We simply... I wouldn't want to be
anywhere near that, let's put it that way.
304
00:30:05,620 --> 00:30:11,920
So in the early 90s I found an extremely
exciting atmosphere.
305
00:30:12,700 --> 00:30:17,240
Those were the years we were developing
the Large Hadron Collider.
306
00:30:18,940 --> 00:30:22,780
ATLAS is the biggest experiment ever built
in particle physics.
307
00:30:23,980 --> 00:30:27,988
We are all pushed by the
same spirit and by the same
308
00:30:27,989 --> 00:30:32,240
awareness of being very
close to discover something big.
309
00:30:34,760 --> 00:30:39,360
In addition to the fundamental science,
which might have interesting applications,
310
00:30:39,900 --> 00:30:44,441
there are the technologies which you develop
in order to make the research possible.
311
00:30:45,060 --> 00:30:48,600
And the World Wide Web is one example of
that.
312
00:30:49,100 --> 00:30:52,970
This is a technology which
was developed in order for
313
00:30:52,971 --> 00:30:55,860
scientists to be able to
collaborate around the world.
314
00:30:56,200 --> 00:31:00,681
And of course it's completely
revolutionized the way that humans interact.
315
00:31:19,280 --> 00:31:20,440
So what's the Web?
316
00:31:21,020 --> 00:31:24,340
It used to be difficult to explain what
the Web would be like.
317
00:31:24,341 --> 00:31:27,700
Now it's difficult to explain why it was
difficult.
318
00:31:30,300 --> 00:31:34,320
But back in the 1980s at CERN it was an
exciting place to be.
319
00:31:35,120 --> 00:31:37,491
Lots and lots of information
systems on different
320
00:31:37,492 --> 00:31:40,260
computers, on different
networks, all incompatible.
321
00:31:41,060 --> 00:31:45,600
So the idea was that one should be able to
communicate by sharing information.
322
00:31:47,260 --> 00:31:52,540
How many of you have actually never
experienced the World Wide Web?
323
00:31:52,541 --> 00:31:53,920
I see one hand.
324
00:31:54,780 --> 00:31:59,120
Two, three, four, five, six, seven.
325
00:31:59,540 --> 00:32:00,540
No, come on.
326
00:32:03,320 --> 00:32:13,060
What was it that made the Web click as the
universal hypertext on a computer network?
327
00:32:13,440 --> 00:32:14,540
It is the URL.
328
00:32:14,920 --> 00:32:18,040
And that is Tim's fundamental
contribution.
329
00:32:19,020 --> 00:32:24,160
We sat under the big tree in the CERN
cafeteria one evening with a beer.
330
00:32:25,080 --> 00:32:28,560
And then I said, we need a catchy title
for it.
331
00:32:28,561 --> 00:32:31,680
And suddenly Tim said, what about World
Wide Web?
332
00:32:32,600 --> 00:32:35,620
I said, yeah, that's great.
333
00:32:35,780 --> 00:32:36,780
It's a bit long.
334
00:32:38,100 --> 00:32:42,460
I like its name, World Wide Web, which
was unpronounceable to French people.
335
00:32:42,840 --> 00:32:44,720
That's why most French people didn't like.
336
00:32:48,720 --> 00:32:52,020
I don't think we've even seen the tip of
the iceberg.
337
00:32:52,440 --> 00:32:55,517
I think the potential of
what the Internet is going
338
00:32:55,518 --> 00:33:00,800
to do to society, both good
and bad, is unimaginable.
339
00:33:02,280 --> 00:33:07,220
I think we're actually on the cusp of
something exhilarating and terrifying.
340
00:33:08,320 --> 00:33:10,100
It's just a tool, though, isn't it?
341
00:33:10,300 --> 00:33:11,300
No, it's not.
342
00:33:11,360 --> 00:33:11,540
No.
343
00:33:12,080 --> 00:33:14,000
No, it's an alien life form.
344
00:33:14,140 --> 00:33:18,420
What do you think of the It's their life
on Mars.
345
00:33:18,600 --> 00:33:20,440
Yes, it's just landed here.
346
00:33:25,260 --> 00:33:29,140
You never spend your nights with me.
347
00:33:29,540 --> 00:33:33,120
You don't go out with other girls either.
348
00:33:34,220 --> 00:33:36,980
You only love your collider.
349
00:33:47,020 --> 00:33:52,040
Tim Berners-Lee and our group of friends
were part of a theatre group.
350
00:33:52,740 --> 00:33:57,740
We used web pages for the clubs and for
work.
351
00:34:00,220 --> 00:34:03,040
And I did think it was a brilliant thing.
352
00:34:04,160 --> 00:34:10,520
When this Cernet picture, all published,
ended up being the first picture of a
353
00:34:10,521 --> 00:34:15,060
band, of an artist, of something social on
the web which was not mere physics.
354
00:34:17,020 --> 00:34:19,440
You only love your collider.
355
00:34:20,620 --> 00:34:24,502
I think that we realised
fairly early on that the
356
00:34:24,503 --> 00:34:28,060
World Wide Web was not
something that it could manage.
357
00:34:30,320 --> 00:34:34,460
The most ambitious attempt ever to
recreate conditions at the beginning of
358
00:34:34,461 --> 00:34:37,100
the Universe is launched this morning in
Switzerland.
359
00:34:38,780 --> 00:34:43,860
Catastrophic claims Professor Otto Rosler,
who went to court to stop the experiment,
360
00:34:43,861 --> 00:34:47,240
warning the Earth could be eaten inside
out.
361
00:34:47,640 --> 00:34:50,062
How many months or
years it takes to eat the
362
00:34:50,063 --> 00:34:53,581
whole Earth cannot be
predicted at the moment.
363
00:34:54,220 --> 00:34:59,961
This might be my last broadcast, because
tomorrow may be the end of the Earth.
364
00:35:00,360 --> 00:35:02,760
You get these things moving around at the
speed of lightning.
365
00:35:03,160 --> 00:35:04,160
Bam!
366
00:35:04,680 --> 00:35:11,460
That story was very beneficial for us
because it attracted a lot of interest and
367
00:35:11,461 --> 00:35:15,160
attention by the public, the media which
was not there before.
368
00:35:16,580 --> 00:35:18,460
Normally we would not publish a switch on
day.
369
00:35:18,640 --> 00:35:19,940
We never did that before.
370
00:35:20,540 --> 00:35:22,900
We were forced into it effectively.
371
00:35:23,580 --> 00:35:28,960
So we had to pick a day and then go flat
out to make it.
372
00:35:31,180 --> 00:35:33,916
We're actually inside the
control room for what is
373
00:35:33,917 --> 00:35:37,100
genuinely the biggest experiment
ever undertaken by mankind.
374
00:35:38,660 --> 00:35:42,500
Nobody was more surprised than me when I
came in at 6 o'clock in the morning and
375
00:35:42,501 --> 00:35:45,938
saw these huge satellite
dishes and big lorries
376
00:35:45,939 --> 00:35:48,320
full of mobile studios
and God knows what.
377
00:35:48,800 --> 00:35:50,220
They were under enormous pressure.
378
00:35:50,420 --> 00:35:51,920
We would normally not accept that.
379
00:35:53,100 --> 00:35:54,620
Don't forget that it made Google.
380
00:35:55,540 --> 00:35:58,200
The Google logo was the LHC that day.
381
00:36:00,680 --> 00:36:03,220
I didn't really know how much of it in the
spotlight I was.
382
00:36:03,520 --> 00:36:06,760
I was doing a running commentary of what
we were doing from step to step.
383
00:36:07,340 --> 00:36:08,460
Let's get started everybody.
384
00:36:09,220 --> 00:36:10,360
Now comes the day of reckoning.
385
00:36:10,361 --> 00:36:13,800
Little did I know that my wife was
watching it at home.
386
00:36:16,040 --> 00:36:19,160
There are innumerable things that could go
wrong.
387
00:36:19,280 --> 00:36:20,760
This has never been done before.
388
00:36:21,960 --> 00:36:28,060
I did not sleep that night before because I
kept thinking I had this list in my brain.
389
00:36:28,340 --> 00:36:28,940
Did we check that?
390
00:36:29,020 --> 00:36:29,540
Did we check this?
391
00:36:29,900 --> 00:36:30,940
What about the voltage?
392
00:36:31,960 --> 00:36:36,380
Everything that could have gone wrong I
was sure it was going to go wrong.
393
00:36:37,420 --> 00:36:40,394
Everybody is staring at
a series of screens above
394
00:36:40,395 --> 00:36:43,420
us and the tension you
could cut with a laser beam.
395
00:36:48,550 --> 00:36:51,790
OK, the next cycle we will inject the beam
into the LHC.
396
00:36:52,370 --> 00:36:53,530
Now we go into new territory.
397
00:36:55,730 --> 00:36:57,990
OK, let's go.
398
00:36:58,970 --> 00:37:05,510
Five, four, three, two, one, zero.
399
00:37:06,410 --> 00:37:07,410
Nothing.
400
00:37:07,530 --> 00:37:08,530
Wave!
401
00:37:27,090 --> 00:37:30,670
Physics has that kind of garage feel to
it.
402
00:37:30,750 --> 00:37:31,750
It is not production.
403
00:37:32,050 --> 00:37:33,170
It involves a lot of tweaks.
404
00:37:33,330 --> 00:37:34,490
It involves a lot of hacking.
405
00:37:34,610 --> 00:37:35,950
We are hackers in the end.
406
00:37:36,150 --> 00:37:37,610
We fix things, they don't work.
407
00:37:37,730 --> 00:37:38,890
We tweak them, we don't work.
408
00:37:41,790 --> 00:37:46,730
Fundamental research is a lot of getting
it wrong until you get it right.
409
00:37:47,550 --> 00:37:49,930
But fortunately we got it right on the
first try.
410
00:37:50,310 --> 00:37:51,310
Never happens.
411
00:37:52,610 --> 00:37:54,950
That was a day, really.
412
00:37:55,590 --> 00:37:57,390
A big emotion.
413
00:37:57,810 --> 00:38:05,370
When you see the thing on which we have
been working for years together with
414
00:38:05,371 --> 00:38:09,630
thousands of colleagues from all over the
world become real.
415
00:38:10,830 --> 00:38:12,710
And they said, wow, here we are.
416
00:38:13,010 --> 00:38:13,310
We manage.
417
00:38:13,770 --> 00:38:14,770
We did it.
418
00:38:16,030 --> 00:38:20,390
It may have looked easy to you but I can
assure you it was only made to look easy
419
00:38:20,391 --> 00:38:25,190
because of the quality of the equipment,
the quality of the software, and above
420
00:38:25,191 --> 00:38:27,313
all, the quality of the
people who have built
421
00:38:27,314 --> 00:38:30,251
this machine and will
operate it in the future.
422
00:38:52,520 --> 00:38:54,793
I got a call, so I went
straight over to the
423
00:38:54,794 --> 00:38:58,281
control room and all
the screens were red.
424
00:38:58,440 --> 00:38:59,440
Red is a bad color.
425
00:39:04,760 --> 00:39:07,617
What we thought it was at
the time was that they had lost
426
00:39:07,618 --> 00:39:10,520
the helium and that it would
take us two months to recover.
427
00:39:12,060 --> 00:39:14,933
I mean, at that point we were
just like days from data and
428
00:39:14,934 --> 00:39:17,880
ah, we've got to lose two more
months because of the helium.
429
00:39:19,520 --> 00:39:22,980
I think it only settled later that we were
talking about a year.
430
00:39:24,600 --> 00:39:29,840
It took a long time to recover emotionally
from it.
431
00:39:33,600 --> 00:39:34,600
It
432
00:39:38,420 --> 00:39:44,420
took about 50 magnets in one sector that
we had to replace.
433
00:39:47,300 --> 00:39:49,620
Fortunately, we had all the spares.
434
00:39:50,060 --> 00:39:53,749
It was just picking
ourselves up, rolling up our
435
00:39:53,750 --> 00:39:56,480
sleeves yet again and
getting on with the job.
436
00:40:00,490 --> 00:40:05,630
Clearly I was frustrated but that was 24
years ago.
437
00:40:05,631 --> 00:40:11,430
24 years after first thinking about the
physics that you could do with the LHC.
438
00:40:12,230 --> 00:40:15,030
So if it was going to take another year or
two, no, that's OK.
439
00:40:21,590 --> 00:40:26,130
So I am Palestinian from Hebron,
West Bank.
440
00:40:27,250 --> 00:40:29,030
Part of this job is international.
441
00:40:29,570 --> 00:40:33,081
We work physics and for
physics and we have to collaborate
442
00:40:33,082 --> 00:40:35,650
with all people regardless
of their background.
443
00:40:41,290 --> 00:40:43,690
I don't care what you believe.
444
00:40:43,950 --> 00:40:47,108
Our goal is to understand
the building blocks of
445
00:40:47,109 --> 00:40:50,670
matter, the fundamental
interactions in nature.
446
00:40:51,430 --> 00:40:55,976
I am a Muslim and I
believe the God Almighty and
447
00:40:55,977 --> 00:40:58,610
I believe there is a
beginning of the universe.
448
00:40:59,910 --> 00:41:04,310
And my goal is not to contradict the God
but to discover the laws of God,
449
00:41:05,190 --> 00:41:06,430
the laws that govern nature.
450
00:41:08,270 --> 00:41:12,750
So my belief, my physics works are side by
side.
451
00:41:12,890 --> 00:41:13,930
There is no contradiction.
452
00:41:15,550 --> 00:41:18,490
Is my belief consistent with my research?
453
00:41:19,150 --> 00:41:19,810
Up to now, yes.
454
00:41:20,130 --> 00:41:21,530
There is no contradiction.
455
00:41:24,050 --> 00:41:28,110
There are so many unanswered questions.
456
00:41:29,030 --> 00:41:33,990
If we really do want to understand why the
universe is the way it is, we need to
457
00:41:33,991 --> 00:41:39,170
understand what the pieces are that make
it up and how those pieces fit together.
458
00:41:40,850 --> 00:41:43,950
The pieces that we know about,
is that all of them?
459
00:41:44,550 --> 00:41:46,190
Or are there more pieces?
460
00:41:47,790 --> 00:41:52,650
When they were building a part of this,
they needed some really, really high
461
00:41:52,651 --> 00:41:58,450
purity brass which was expensive and
difficult to get hold of.
462
00:41:58,910 --> 00:42:04,950
But some of the Russian colleagues
realized that they had loads of World War
463
00:42:04,951 --> 00:42:09,510
II shell casings made out of exactly the
right quality brass necessary.
464
00:42:10,230 --> 00:42:15,409
And so over a million World
War II shell casings were collected,
465
00:42:15,410 --> 00:42:20,310
melted down and turned into
our calorimeter right in here.
466
00:42:26,920 --> 00:42:31,600
CERN was one of the holes in the Iron
Curtain during the Cold War.
467
00:42:32,560 --> 00:42:35,558
Because all the people
from the other side of the
468
00:42:35,559 --> 00:42:38,881
Iron Curtain could come
to sell and vice versa.
469
00:42:48,960 --> 00:42:55,400
CERN is the only organization which had in
its foundation the double role to promote
470
00:42:55,401 --> 00:43:00,060
science and improve the relations between
countries.
471
00:43:01,660 --> 00:43:02,680
The moment is at hand.
472
00:43:02,900 --> 00:43:06,660
President Reagan now is at a lakeside
mansion about eight miles north of Geneva.
473
00:43:06,920 --> 00:43:08,985
And it is there that the
President will meet this
474
00:43:08,986 --> 00:43:11,380
morning with Mikhail
Gorbachev of the Soviet Union.
475
00:43:11,880 --> 00:43:14,880
The first meeting between the leaders of
the two most powerful forces in the
476
00:43:14,881 --> 00:43:17,620
history of civilization in more than six
years now.
477
00:43:29,890 --> 00:43:33,514
When I was Director General
of CERN, I got a call from the
478
00:43:33,515 --> 00:43:37,510
head of the American delegation
to prepare the discussion.
479
00:43:37,790 --> 00:43:44,970
We said, look, we need a place which is
respected by both sides, where we can
480
00:43:44,971 --> 00:43:48,390
freely and informally discuss the
problems.
481
00:43:49,830 --> 00:43:51,796
So I invited a small
group, both from the
482
00:43:51,797 --> 00:43:55,331
Russians and the
Americans, to dinner at CERN.
483
00:43:56,030 --> 00:44:00,150
And after they first dosed, I left them
alone and said goodbye.
484
00:44:01,430 --> 00:44:04,390
I called for a fresh start and we made
that start.
485
00:44:04,870 --> 00:44:07,717
I can't claim that we had
a meeting of the minds on
486
00:44:07,718 --> 00:44:10,531
such fundamentals as
ideology or national purpose.
487
00:44:11,130 --> 00:44:15,350
But we understand each other better,
and that's a key to peace.
488
00:44:17,090 --> 00:44:22,070
I think if, in the end, Gorbachev could
sign the first disarmament agreement,
489
00:44:22,071 --> 00:44:25,990
it was, I believe, with the help of the
physicists.
490
00:44:52,630 --> 00:44:55,373
The Large Hadron
Collider is a machine for the
491
00:44:55,374 --> 00:44:58,891
world because it's the
only machine of that type.
492
00:44:58,970 --> 00:45:02,269
It brings the world
forward, and it can only
493
00:45:02,270 --> 00:45:05,771
work because the
whole world is involved.
494
00:45:13,600 --> 00:45:18,900
It could not immediately start with the
highest possible energy for which the LHC
495
00:45:18,901 --> 00:45:22,040
was designed, so we decided to go up very
slowly.
496
00:45:22,680 --> 00:45:26,780
But we reached the highest energy ever
with an accelerator on Earth.
497
00:45:27,440 --> 00:45:30,715
It's a bit like an
explorer, because I see
498
00:45:30,716 --> 00:45:33,780
something which nobody
else had seen before.
499
00:45:34,260 --> 00:45:35,260
It's brilliant.
500
00:45:41,900 --> 00:45:47,260
40 million pictures per second of these
collisions, roughly 150 million channels,
501
00:45:47,720 --> 00:45:49,620
and it's a three-dimensional picture.
502
00:45:54,120 --> 00:45:58,280
Of course, then we were in a rush to find
the Higgs particle.
503
00:45:58,500 --> 00:46:00,660
I mean, that was what we wanted to see.
504
00:46:02,540 --> 00:46:05,467
What's left to fill the
gap between theory and
505
00:46:05,468 --> 00:46:08,721
experiment, that's the
Higgs boson contribution.
506
00:46:10,800 --> 00:46:14,376
For particle physicists
discovering the Higgs
507
00:46:14,377 --> 00:46:18,401
boson, this would be
like landing on the moon.
508
00:46:21,840 --> 00:46:23,000
It's not just a particle.
509
00:46:23,720 --> 00:46:25,540
It's not just a thing that gets produced.
510
00:46:25,600 --> 00:46:30,202
It is a clue to one of the
most fundamental concepts
511
00:46:30,203 --> 00:46:34,480
of our lives and worlds,
which is, how do we get mass?
512
00:46:41,610 --> 00:46:43,550
It was sort of bam, bam, bam.
513
00:46:43,590 --> 00:46:46,190
We were working along, we were doing
everything, calibrating the detector,
514
00:46:46,191 --> 00:46:48,410
and then suddenly there was something
there.
515
00:46:48,610 --> 00:46:50,630
I mean, we thought, okay, God,
is this the Higgs?
516
00:46:50,830 --> 00:46:51,910
You know, could this be it?
517
00:46:51,950 --> 00:46:55,851
You know, of course, there was this excitement
that we knew, but it happened so fast.
518
00:47:00,660 --> 00:47:06,940
You check and recheck, and then you see
suddenly this peak or this number of
519
00:47:06,941 --> 00:47:09,740
pictures indicating something interesting
growing.
520
00:47:11,460 --> 00:47:14,420
People were working days and nights,
looking at the data.
521
00:47:16,300 --> 00:47:20,220
There was something special going on.
522
00:47:24,450 --> 00:47:27,950
We decided, okay, we will have a seminar.
523
00:47:28,970 --> 00:47:30,310
But we didn't know yet.
524
00:47:30,311 --> 00:47:33,790
Is it a discovery or is it close to a
discovery?
525
00:47:45,480 --> 00:47:49,200
Today we hear two presentations from the
two experiments, ATLAS and CMS,
526
00:47:49,520 --> 00:47:52,220
on their update on a search for a certain
particle.
527
00:47:54,800 --> 00:47:58,120
We have a magic limit in particle physics.
528
00:47:58,900 --> 00:48:03,480
When we cross this threshold of evidence,
then we can call it a discovery.
529
00:48:03,800 --> 00:48:07,644
We needed to cross this
threshold in both experiments
530
00:48:07,645 --> 00:48:10,461
because the cross-check
is absolutely vital.
531
00:48:12,000 --> 00:48:13,674
There were many, many
people who had made the
532
00:48:13,675 --> 00:48:15,761
history of CERN,
previous director-general.
533
00:48:16,420 --> 00:48:18,320
Peter Higgs was there, Francois Anglaire.
534
00:48:19,880 --> 00:48:24,520
The day of the announcement was really
kind of, not only was the world learning
535
00:48:24,521 --> 00:48:28,040
about it, but also half the community was
learning about the other half.
536
00:48:28,440 --> 00:48:31,478
So this distribution
is extremely clean,
537
00:48:31,479 --> 00:48:36,001
except one big spike
here in this region here.
538
00:48:39,680 --> 00:48:42,380
So, zooming in this region.
539
00:48:49,720 --> 00:48:54,260
We have observed a new particle consistent
with Higgs's proposal.
540
00:48:55,580 --> 00:48:57,660
As a layman I would now say...
541
00:48:59,080 --> 00:49:00,080
I think we have it.
542
00:49:01,220 --> 00:49:02,220
Do you agree?
543
00:49:10,470 --> 00:49:15,316
Maybe one more round of
applause to all the guys who
544
00:49:15,317 --> 00:49:20,190
supported the whole project
for more than 25 years here.
545
00:49:20,350 --> 00:49:21,350
All the way.
546
00:49:25,970 --> 00:49:29,450
Just take a step back and look at what we
achieved.
547
00:49:30,010 --> 00:49:31,010
It was huge.
548
00:49:43,250 --> 00:49:46,190
The elementary particles wouldn't have a
mass.
549
00:49:46,750 --> 00:49:50,030
They would fly through the universe with
the speed of light.
550
00:49:50,290 --> 00:49:52,450
No chance to form composite matter.
551
00:49:52,910 --> 00:49:54,630
No chance to form us.
552
00:49:54,970 --> 00:49:56,230
No chance to form the Earth.
553
00:49:57,430 --> 00:49:58,970
And now we found the explanation.
554
00:49:59,650 --> 00:50:00,650
We found it.
555
00:50:02,150 --> 00:50:04,630
It's a great moment.
556
00:50:06,030 --> 00:50:07,030
I
557
00:50:22,100 --> 00:50:25,140
have to say I was pretty emotional.
558
00:50:27,220 --> 00:50:30,900
I'm not quite sure whether I had tears in
my eyes.
559
00:50:31,040 --> 00:50:32,220
Peter Higgs certainly did.
560
00:50:32,960 --> 00:50:38,500
So this was 48 years after they had
proposed their theory.
561
00:50:40,060 --> 00:50:42,787
Well, I would like to
add my congratulations to
562
00:50:42,788 --> 00:50:45,160
everybody involved in this
tremendous achievement.
563
00:50:46,100 --> 00:50:52,320
For me, it's really an incredible thing
that has happened in my lifetime.
564
00:51:28,280 --> 00:51:32,760
Just at the moment where you say,
OK, that was worth all my work,
565
00:51:33,060 --> 00:51:37,720
this moment, this day, and basically you
then stop working.
566
00:51:37,920 --> 00:51:39,900
After that seminar, we just celebrated.
567
00:51:40,180 --> 00:51:42,240
It was a day full of champagne and beer.
568
00:51:42,640 --> 00:51:43,640
Perfect.
569
00:51:47,850 --> 00:51:53,470
I think the one good thing that I had
going for me when I started this was that
570
00:51:53,471 --> 00:52:00,071
I was naive and never realised the mountain
that we had to climb to actually succeed.
571
00:52:06,260 --> 00:52:10,140
You look at the experimental teams that
discovered the Higgs boson.
572
00:52:10,520 --> 00:52:14,020
They include Russians and Americans.
573
00:52:15,020 --> 00:52:18,560
They include Chinese and Europeans.
574
00:52:18,561 --> 00:52:21,920
They include Indians and Pakistanis.
575
00:52:22,540 --> 00:52:25,180
They include Israelis and Palestinians.
576
00:52:27,900 --> 00:52:33,340
This is an endeavour which, I think,
really unifies the human race.
577
00:52:38,180 --> 00:52:40,000
The situation is complex today.
578
00:52:40,620 --> 00:52:43,100
The war in Ukraine does have an impact.
579
00:52:43,820 --> 00:52:47,831
Last year, the CERN
Council decided to terminate
580
00:52:47,832 --> 00:52:50,920
the collaboration with
some Russian institutes.
581
00:52:54,600 --> 00:52:59,900
So there is one institute based in Russia
that we're still working with.
582
00:53:02,000 --> 00:53:06,220
Now the CERN Council must decide whether
it wants to keep that long-standing
583
00:53:06,221 --> 00:53:09,220
collaboration going or whether it wants to
cut all ties.
584
00:53:12,960 --> 00:53:18,861
Sanctioning Russia and Belarus, yeah,
that contradicts the CERN Foundation.
585
00:53:19,580 --> 00:53:26,180
So CERN was established after the Second
World War in the ash of Europe in 1954.
586
00:53:27,640 --> 00:53:34,240
And in the 1950s, 60s, 70s, at the height
of the Cold War, World War, Americans,
587
00:53:34,700 --> 00:53:38,420
Germans, West Europe, Russians,
Soviets worked together, so what changed?
588
00:53:38,820 --> 00:53:39,820
Why don't you keep that?
589
00:53:44,200 --> 00:53:46,890
You cannot generalise to all the people.
590
00:53:47,250 --> 00:53:50,704
You cannot generalise
to all Russian or Ukrainian,
591
00:53:50,705 --> 00:53:53,631
the decision of a few people
in the government, maybe.
592
00:53:56,050 --> 00:53:58,570
I know these people, they are against war.
593
00:53:58,970 --> 00:54:02,310
And they are paying for something that is
not their fault.
594
00:54:08,240 --> 00:54:13,560
So I'm really curious now to see whether
Fabiola somehow has said something.
595
00:54:14,080 --> 00:54:14,640
There is something.
596
00:54:15,000 --> 00:54:16,000
I'll wait.
597
00:54:16,300 --> 00:54:18,040
An important item on the CERN Council.
598
00:54:18,400 --> 00:54:21,460
Has the Council decided not to terminate
the agreement?
599
00:54:21,960 --> 00:54:22,500
That's good.
600
00:54:22,860 --> 00:54:30,620
I'm very happy to read that CERN remains
in its tradition.
601
00:54:31,260 --> 00:54:32,260
Very good.
602
00:54:33,140 --> 00:54:38,000
If the Council had not taken that decision
and decided to terminate the agreement,
603
00:54:38,160 --> 00:54:41,820
that would have been the end of any
relation with the Russian Federation.
604
00:54:45,720 --> 00:54:47,520
This is really the nerve centre.
605
00:54:47,740 --> 00:54:49,440
This is where everything happens.
606
00:54:50,080 --> 00:54:53,920
How can we make sure that we continue
being the number one lab?
607
00:54:53,921 --> 00:54:58,540
So it's projecting CERN in decades away
from today.
608
00:55:00,760 --> 00:55:03,820
This is why we're doing this feasibility
study.
609
00:55:04,640 --> 00:55:07,920
You know, should we have a super,
super-duper large accelerator,
610
00:55:08,900 --> 00:55:12,540
it's going to be three times the size of
the current LHC.
611
00:55:16,510 --> 00:55:17,810
What is dark matter?
612
00:55:18,070 --> 00:55:19,850
That's the question I'm looking for.
613
00:55:20,230 --> 00:55:25,470
We know it's there and it must be there in
an enormous amount, about four times more
614
00:55:25,471 --> 00:55:29,270
of this than the visible mass of the
universe.
615
00:55:32,600 --> 00:55:38,340
We're in the control room of my experiment
on the space station.
616
00:55:39,960 --> 00:55:44,660
The highest energy particle comes from the
cosmos.
617
00:55:52,760 --> 00:55:58,020
To know the origin of Hubble, you have to
go above the Earth's atmosphere.
618
00:55:59,000 --> 00:56:04,600
Thank you very much for the great ride and
safe delivery of AMS to the station.
619
00:56:05,840 --> 00:56:10,862
Your support and fantastic
work has taken us one step
620
00:56:10,863 --> 00:56:15,020
closer to realizing the
science potential of AMS.
621
00:56:19,040 --> 00:56:27,440
We have some very, very important results
that correspond to dark matter conditions.
622
00:56:29,020 --> 00:56:32,652
So we have learned
from this experiment,
623
00:56:32,653 --> 00:56:37,100
cosmic rays behave in a
way nobody dreamed of.
624
00:56:37,560 --> 00:56:38,860
That's why it's so interesting.
625
00:56:47,280 --> 00:56:53,520
It's the mystery of life and we have to
accept that there are things that are much
626
00:56:53,521 --> 00:56:59,720
bigger, much more complex than our brain
and our imagination can capture.
627
00:57:11,550 --> 00:57:15,490
We are made of sub-nuclear universe.
628
00:57:16,450 --> 00:57:18,730
We are pieces of the sub-nuclear universe.
629
00:57:19,610 --> 00:57:24,810
Believe it or not, it's the real origin of
existence.
630
00:57:31,900 --> 00:57:33,080
Do
631
00:57:36,660 --> 00:57:44,720
you sometimes want to wake up to the
singularity we once were?
632
00:57:47,960 --> 00:57:53,660
For every atom belonging to me as good
belongs to you.
633
00:57:55,000 --> 00:58:01,508
When Earth was sky and
animal was energy and rock
634
00:58:01,509 --> 00:58:07,980
was liquid and stars were
space and space was not.
635
00:58:10,720 --> 00:58:20,040
Only a tiny dot brimming with is,
is, is.
636
00:58:23,930 --> 00:58:25,330
Everything.
637
00:58:27,250 --> 00:58:28,250
Home.
