1
During COVID, everyone was sequestered in their own corners of the world.
2
I had the strange fortune of being sequestered here aboard the Ocean Explorer,
3
one of the most advanced research vessels on the planet,
4
filming a show for National Geographic.
5
The ship was designed not just for research, but also for storytelling.
6
My job was to travel the world and show people what exploration is like from the perspective of an engineer.
7
When I tell people this,
8
they usually have three questions.
9
What was it like?
10
What did you learn?
11
And how did you get the job?
12
I'll go backward.
13
I wasn't always a great engineer.
14
I wasn't even a good student.
15
I spent more time tinkering than doing homework.
16
But I love engineering, and that has led me on an incredible journey.
17
With friends, I built low-cost underwater robots designed to democratize exploration,
18
and that democratization drew the attention of the show's producers.
19
You can watch the show to see what we discovered,
20
but for me, the most powerful moments we're seeing things that no one had ever seen before,
21
using the tools that we had built.
22
In the Azores, we teamed up with Rui Pareto,
23
renowned whale biologist who spent decades studying sperm whales.
24
These giants can dive to over a mile deep to hunt,
25
and we know very little about what they do when they're down there.
26
So to find out, Rui had put together a very DIY tag.
27
It used a taken-apart action camera.
28
It had a light, there was a radio beacon,
29
and it had suction cups designed to stick to the whale for a few hours
30
and then pop up and float to the surface.
31
It was very DIY, but even on an advanced research ship,
32
building your own tools is often the way to get the information you need.
33
It barely worked.
34
We had to spend nights soldering and improvising to try to get it going.
35
And at like 2 in the morning,
36
we finally got it going.
37
And while I overslept, Drew was already out on the boat.
38
He placed the tag on a whale,
39
and I remember him radioing back.
40
The tag was on.
41
Okay, a huge amount of suspense.
42
Would it ever come back to the surface?
43
Or would it flood with water?
44
Would the battery die?
45
Would the camera work?
46
We had no idea.
47
But it did come up.
48
We found it.
49
We took it back to the ship.
50
And fingers were crossed.
51
Finally, we opened it up.
52
There was no water inside.
53
Oh, my God.
54
We pulled out the SD card,
55
and like with bated breath,
56
we put it in the computer and waited for the files to load.
57
And oh my God, we had footage from the back of a sperm whale.
58
Oh my God.
59
Rui and I were losing it.
60
The first thing we saw was the whale's head and back as she descended into the bottom.
61
You could hear the water rushing by as she swam faster and faster into the deep particles rushed by the camera.
62
And the water pressure was so immense from the speed that eventually the suction cup started to come loose.
63
I thought that was going to bit.
64
We were going to lose it.
65
But one suction cup miraculously held on.
66
And it caused the tag to rotate backward.
67
And now we can see the sails massive fluke.
68
These can be 16 feet across on some whales,
69
driving her into the depths.
70
And as it got deeper,
71
we started hearing on the camera's microphone clicking.
72
You guys hear that?
73
That is echolocation.
74
That is the sound of the sperm whale hunting by listening for echoes bouncing off of prey.
75
I couldn't believe it.
76
And it didn't seem like she caught anything that time,
77
but as she came shallower in the light group rider,
78
we were just, like, amazed at what we were seeing.
79
It didn't seem like this was possible.
80
And then we started hearing a different sound.
81
It was a rapid series of clicks.
82
That's called codas.
83
This is the way sperm whales used to communicate with each other.
84
So we were hearing her talking to another whale.
85
We could not believe our ears and then we couldn't believe our eyes.
86
Rui and I were losing it.
87
The other whale came into the shot,
88
and they were talking back and forth.
89
They were swimming and bumping alongside each other.
90
For minutes, we watched in disbelief as we watched this exchange of these two whales.
91
Friends, family, lovers, we can never know for sure.
92
But what we were witnessing was something no one had ever seen before.
93
I remember seeing the bond that they had with my eyes and also feeling it with my heart.
94
The footage we had seen was not just data.
95
This was an experience of life.
96
It was reminding me why exploration really matters.
97
It's not just about understanding the world with our logical minds.
98
I believe exploration has huge potential to allow us to experience things with emotion
99
and feel the context of why we're here on Earth.
100
We saw that they even dived together,
101
and that is really something that moved me.
102
That one last dive, seeing that maybe it's not even such a lonely place down there after all.
103
We are all here together,
104
and that is something extremely powerful.
105
So we are living in an era now where our tools
106
can give us amazing ability to understand in ways never before possible.
107
The same advances that have put computers in our pockets
108
and access to almost unlimited information on our screens can also allow us to explore in brand new ways.
109
Our tools no longer limit what we can understand.
110
It's more that our understanding is limited by curiosity.
111
So the question isn't, what can we explore?
112
So much is already within our reach.
113
The real question is, what will we wonder about next?
114
Thank you very much.
115
Thank you.

Contesto e sfondo

Nel video TED di Eric Stackpole, l'autore condivide la sua straordinaria esperienza a bordo dell'Ocean Explorer, una delle navi di ricerca più avanzate al mondo. Durante il periodo di COVID, Stackpole ha avuto l'opportunità di esplorare gli oceani e documentare la vita marina, in particolare quella delle balene. Attraverso la sua passione per l'ingegneria e l'avventura, ha creato strumenti per monitorare e studiare le balene, rivelando dettagli mai visti prima sull'habitat di questi animali straordinari. La sua storia evidenzia l'importanza della curiosità e della creatività nella scienza e nella comunicazione.

Top 5 frasi per la comunicazione quotidiana

  • “Cosa hai trovato a proposito delle balene?” - Una domanda utile per avviare una conversazione sulla fauna marina.
  • “Ho costruito un robot sottomarino.” - Utile per descrivere progetti o esperienze tecnologiche.
  • “Qual è stata la parte più emozionante dell'esplorazione?” - Una domanda che stimola la riflessione e il dialogo.
  • “Hai mai visto un animale nella sua habitat naturale?” - Un modo per condividere esperienze personali legate alla natura.
  • “Come funziona l’echolocalizzazione?” - Una domanda tecnica che può portare a discussioni più approfondite sulla biologia animale.

Guida passo-passo per il shadowing

Per affrontare le sfide di questo video, puoi seguire questi passaggi per migliorare la tua pronuncia inglese e affinare le tue capacità di shadow speech:

  1. Ascolta attentamente: Guarda il video una prima volta senza sottotitoli per familiarizzare con l'argomento e il tono di voce di Stackpole.
  2. Dividi il contenuto: Suddividi il video in sezioni più piccole. Questo ti permetterà di concentrarti su frasi e pronunce specifiche.
  3. Ripeti ad alta voce: Inizia a ripetere a voce alta, seguendo il ritmo di Stackpole. Utilizza il metodo di shadowspeak per emulare la sua intonazione e pronuncia.
  4. Registrati: Fai una registrazione della tua voce mentre parli. Questo ti aiuterà a identificare aree di miglioramento e a seguire i progressi.
  5. Confronta e migliora: Ascolta la tua registrazione e confrontala con il video. Focalizzati su dettagli come l'accento, il ritmo e la fluidità.

Utilizzando questi passaggi, puoi migliorare significativamente la tua competenza linguistica e rendere più efficace il tuo esercizio di shadow speech.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
