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.

文脈と背景
このTEDトークは、エンジニアであり映像製作者であるエリック・スタックポールさんが、彼の冒険や海洋探査の経験を共有するものです。COVID-19の影響で、スタックポールさんは先進的な研究船「オーシャンエクスプローラー」に隔離され、ナショナルジオグラフィックのために番組を制作していました。この船は、探査だけでなく、ストーリーテリングのためにも設計されています。彼は、エンジニアの視点から探査の体験を多くの人に伝えることを目指していました。
日常会話のための5つのフレーズ
- 「私はエンジニアです。」 - 自己紹介で使える基本的なフレーズ。
- 「初めて見たものを見ました。」 - 新しい経験を共有する際に役立ちます。
- 「どうやってその仕事を得ましたか？」 - 興味を持って質問するのに最適。
- 「私たちはDIYの道具を使っていました。」 - 創意工夫を強調する表現。
- 「彼女はエコーロケーションを使っています。」 - 特定の知識を共有する際に良いフレーズ。
ステップバイステップ シャドーイングガイド
このビデオは、エリック・スタックポールさんの独自の視点からの海洋探査を描いています。英語学習の一環として、英語シャドーイングを行う際の具体的なアプローチを以下に示します。
- ビデオを視聴する：最初に全体を通して視聴し、内容を把握しましょう。特に彼の口調や発音に注目してください。
- セクションごとに分ける：ビデオを短いセクションに分け、各セクションを繰り返し聴いてください。特に難しい部分は何回か戻って確認しましょう。
- 声に出してリピートする：発音やイントネーションに注意を払いながら、彼の言葉を声に出してリピートします。英語の発音を良くするポイントです。
- フレーズを変える：彼の使用したフレーズを自分の言葉に置き換え、話す練習をしてみましょう。例えば、彼の質問を自分の経験に基づいた質問に変えてみるのも良いです。
- 録音して振り返る：自分の声を録音し、後で聴いてみてください。どの部分を改善できるかを確認し、最新のIELTSスピーキング対策に役立てましょう。
この方法を通じて、YouTubeで英語学習や英語スピーキング練習を効果的に進めることができます。エリック・スタックポールさんの冒険を体験しながら、楽しく学んでいきましょう!
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
