Transcriber: Andrea McDonough Reviewer: Bedirhan Cinar I'm going to take you on a journey into some hidden worlds inside your own body using the scanning electron microscope.
2
These microscopes use a beam of electrons to illuminate things that are too small to be seen by the photons of visible light.
3
And to put this in context, if you mentally divide one tiny millimeter into a thousand parts, each one of those parts is a micrometer, or micron for short.
4
If you then divide one micron into another thousand parts, each one of those is a nanometer.
5
And it's nanometers and microns that are the domain of the scanning electron microscope.
6
So, let's start with something on the body that we can measure at about 100 microns wide, and that would be a human hair, which now you can see is covered with scales, just like all of our hairs, and in fact, just like all mammal hairs.
7
We're going to plunge into the body now, and we've landed in the thyroid gland.
8
Here we're looking at proteins that are being secreted into a storage chamber where they are going to develop into the mature thyroid hormones before being released into the body.
9
And at this point you might be wondering if these colors are real.
10
The answer is no.
11
Electron images only happen in black and white.
12
I often colorize my images for various reasons, but I don't change the structures, so the strucutres that you're seeing are all exactly as they were when I photographed them in the microscope.
13
We're going to take a detour and zoom in on the heart muscle now.
14
And the heart muscle has this curious structure that's kind of like corrugated cardboard.
15
That's what allows the heart to expand and contract as it's beating.
16
Let's go look at a lung with pneumonia.
17
Here we've got a white blood cell poking around in an air sac, looking for something to clean out like a little vacuum cleaner.
18
This is your immune systems at work.
19
So what are the kinds of things that we don't want to be breathing, besides bacteria and viruses?
20
Well, we all know to stay away from asbestos and now we can see why.
21
This is a close-up view of the mineral that asbestos is made from, and now you can see that it's composed of many tiny, fine little needles.
22
Each one of those needles is a single crystal.
23
And in this picture, they're begininng to pry apart and tangle up into a spiky mess, not for breathing.
24
What else might we want to avoid breathing?
25
Well, how about diesel fuel?
26
We're looking here at the particles of diesel soot, and these are extraordinarily tiny.
27
In fact, each one of these little particles is only about 50 nanometers wide.
28
We'll go and look at some blood now.
29
We've got a collection of nice, fat, happy, healthy red blood cells, but they're all tangled up in a network of fibers.
30
This is how the body makes a blood clot.
31
And so, it surrounds a group of red blood cells and other cells, and traps them so the blood can't flow.
32
We've got two more blood cells here, but they're not normal like the ones in the blood clot image.
33
These are distorted.
34
You can see that they're curling up and beginning to grow what's going to become spikes.
35
These are sickle cells and these are what cause the condition of sickle cell amenia.
36
We've gone into the mouth now and we've landed on dental plague, which you can see is covered with bacteria, and in fact dental plague is host to about 1,000 different species of bacteria.
37
Lovely to think about.
38
And now we are on to other teeth.
39
We're on the surfaces of the, or the internal surfaces of the teeth themselves.
40
The smaller one is a baby tooth that had just fallen out of the mouth of a young friend of mine, and I want to call your attention to the little holes.
41
Those little holes are the tops of a whole network of tiny little tubes that circulate nourishing fluids inside your teeth.
42
And we can see those tubes a little better in the larger picture because some of them are in cross-section.
43
But in fact, this larger picture is showing you a portion of a tusk, which you may know is simply a great big, elongated tooth, so you would expect to see the same features between your teeth and a tusk.
44
But that larger tusk picture is also rough by comparison to the young baby tooth.
45
That's because it's many, many thousands of years old.
46
It's also partly fossilized.
47
And, between these two pictures, now you can see how your teeth relate to the tusk of an Ice Age mammoth.
48
We're shooting up north now into the brain, and we can see these pink cells down at the bottom.
49
Those are the neurons of memory.
50
And I'm going to leave you with this picture because I know you're going to take a lot of happy memories away from your exciting day at TED and now you can visualize where those memories are being stored in your own brain.
51
Thank you.

맥락 및 배경

딜 브레거는 자신의 영상에서 인체 내부의 숨겨진 세계를 탐험하는 여정을 제공합니다. 이 과정에서는 스캐닝 전자현미경을 사용하여 인간의 신체를 구성하는 미세한 세계를 시각화합니다. 이 영상은 신체의 구조와 기능을 이해하고자 하는 이들에게 큰 통찰을 줍니다. 고해상도의 이미지를 통해 단순한 것에서부터 복잡한 생물학적 과정까지 다양한 내용을 다룹니다. 영어 회화 연습이나 IELTS 스피킹 준비를 위한 훌륭한 자료가 될 수 있습니다.

일상 소통을 위한 5가지 주요 문구

  • “이것은 어떻게 작용하나요?” - 구조나 과정에 대한 설명을 요청할 때 유용합니다.
  • “나는 이것을 볼 수 있나요?” - 시각적인 자료나 이미지를 요청할 때 활용할 수 있습니다.
  • “이 색깔은 무엇을 의미하나요?” - 정보 또는 데이터의 의미를 묻는 질문입니다.
  • “어떤 예시가 있나요?” - 명확한 설명을 위해 추가적인 예를 요구할 때 사용합니다.
  • “이 과정을 좀 더 자세히 설명해 주시겠어요?” - 심층적인 이해를 위해 추가적인 설명을 요청할 때 유효합니다.

단계별 섀도잉 가이드

영어 회화를 더욱 효과적으로 익히기 위해 shadowing site에서 제시하는 단계별 섀도잉 전략을 적용해 보세요.

  1. 영상 선택: 딜 브레거의 영상을 선택하고 집중하여 시청합니다. 주요 아이디어를 파악하세요.
  2. 필기: 들은 내용을 간단히 메모해보세요. 특히 핵심 문구나 표현에 주목합니다.
  3. 반복 청취: 여러 번 듣고, 복잡한 문구를 찾는 데 집중하세요. 모르는 단어는 따로 정리합니다.
  4. 따라 읽기: 목소리를 따라하며 발음과 억양에 주의하세요. 이 단계에서 유튜브 영어 공부를 위한 좋은 연습이 될 수 있습니다.
  5. 발음 연습: 섀도잉 후, 직접 문장을 소리 내어 말해보세요. 이를 통해 IELTS 스피킹 준비에 도움을 줄 수 있습니다.

이 과정을 통해 일상적인 영어 대화 능력을 향상시키고, 저자와의 직접적인 소통을 시도해 보세요.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
