1
Hello.
2
Oh, hello.
3
Am I speaking with Francis Halsan?
4
Speaking.
5
Hello, my name is Adam Smith.
6
You are lucky you're talking to me because I only answered because, you know, I thought it was a call from Sweden,
7
but I'm glad to talk to you.
8
I'm very glad to talk to you.
9
Thank you very much indeed.
10
And lucky me that you recognize the Swedish prefix.
11
Thank you.
12
May I just start by asking, how did the news actually reach you?
13
How did you learn that you'd been awarded the Nobel Prize?
14
You know, I am travelling.
15
I travelled between, I was at a science festival in Bergamo over the weekend.
16
I was sitting in my hotel room writing a proposal.
17
As I joked in one of the meetings, I hope it helps to get it funded.
18
Let's hope so, because finding time to finish it is going to be hard, I'm afraid, yes.
19
Yes, I'm afraid so too.
20
You know, just like Ice Cube, I have talented collaborators, so they always help me survive.
21
I'll come through this one as well.
22
I mean, if we think of Ice Cube and its extraordinary beauty
23
and size there in the translucent ice under the South Pole, you and your collaborators must be very proud
24
well yeah and in fact my uh main reaction to this project over time was not proud
25
but was surprised you know i gave a talk very early
26
on the in the project at a conference in venice where I said, this is a detector, Deo Volante, which means God willing.
27
And I listed all the hurdles we had to overcome.
28
And among these hurdles, you know, we overcame them all, evidently.
29
That's why I'm here.
30
But was the fact that we didn't really know what the optics of the ice was, which is crucial because it's a particle detector that detects light.
31
And so we made this incredible discovery that blue light that we detect can travel for hundreds of meters through this ice.
32
And that was totally unexpected as well.
33
So beyond all the other risks of whether hot water drilling would work and whether we could beat the backgrounds,
34
this was what really made the project possible and that was pure luck.
35
After the fact that it's totally normal,
36
this is ancient snow that fell on Antarctica 50 ,000 years ago and it's ultra -pure and that's why it's so transparent.
37
But we really didn't have the guarantee of that.
38
But I suppose fortune favours the bold and in your case everything fell into place.
39
As I said, at every step, my reaction was surprise rather than pride.
40
And now this ushers in this dawn of a new era of neutrino astronomy.
41
I know that it's early days, but what do these neutrinos allow us to see?
42
Well, the first source we really identified by ourselves was an active galaxy
43
and the data of that active galaxy tell us
44
that the neutrinos are produced very close to the black hole at the center of that galaxy.
45
And it's an active galaxy, so it has a supermassive black hole
46
and the core of the galaxy is surrounded by plasma which produces the target to produce these neutrinos.
47
This is obviously a place from which light doesn't escape.
48
It can, with great difficulty, maybe be studied with radio telescopes. But
49
so our first detection of a source is already an example
50
of looking into the very close regions of the black hole where presumably only neutrinos escape.
51
That's extraordinary.
52
This is just one example of the concept for which we all thought that the neutrino astronomy was promising.
53
As someone mentioned in the press conference,
54
it's actually, in retrospect, the most amazing thing is that we got funded for this project.
55
The National Science Foundation should take great credit for this.
56
And also the environment that you were able to work in, Wisconsin, which has obviously been very supportive for you.
57
Yes, incredibly.
58
In two ways.
59
Wisconsin has always been a place that has tolerated unconventional physics and unconventional ideas.
60
We got instant support at the very early stages of the project.
61
Where, as I said, this project, everybody thought, is a cute idea that won't work.
62
We got the support from the chancellor of the administration, and we were not just lucky.
63
In a sense that the University of Wisconsin had a decision to create a laboratory
64
that could actually build equipment of the type required and the size and the sophistication required for this project.
65
It's called the Physical Sciences Laboratory.
66
It's kind of a non -profit, high -tech lab.
67
And the very talented technicians, engineers that were available to us there played a major role.
68
And that's where, you know,
69
for instance, the hot water drilling equipment that was so critical for achieving the deployment of these sensors.
70
That's where it was designed and built.
71
And so most universities over the years had gotten rid of these labs,
72
but Wisconsin was one of the few places which maintained this capability, and that's what made IceCube possible there.
73
I just wanted to finish by just reflecting on this extraordinary thing
74
that this new era will allow you to use neutrinos to look to the very edges of the universe
75
and to the very beginnings of time.
76
I mean, there is so much to be discovered, isn't there?
77
That's right.
78
And so someone asked me what will be this, what will the neutrino astronomer be like 50 years from now?
79
There's no way to answer that question.
80
I wouldn't like to answer that question for, if you ask me, one year from now.
81
you know we have been consistently making new discoveries over the 15 years
82
that we have been taking data that's my my real wish
83
that this may continue
84
and it will young people around the world will be saying this is the field for me then i hope
85
so it's been a joy speaking to you thank you very
86
much indeed thank you very much thank you bye bye now

Qu'est-ce que la technique du Shadowing ?
Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
