1
Einstein is celebrated for giving us the special theory of relativity.
2
The fact that nothing goes faster than light, time is the fourth dimension.
3
But he didn't come up with the equations.
4
That was the interpretation, the narrative of the equations.
5
And it's the same with any other theory in physics.
6
With quantum mechanics it's different.
7
We have the equations of quantum mechanics, but we can't agree on what that equation means.
8
Schrodinger's equation being the most famous one, we can crank the handle and produce numbers from the equation, but the narrative, the story,
9
the explanation is still something that we're arguing about.
10
And that bugs me.
11
By the end of the 19th century, it was already known that we needed some new physics to explain mysterious phenomena,
12
X -rays, like radioactivity, that energy seemed to be coming out of nowhere, to understand the behavior or the structure of the atom.
13
And so when quantum mechanics came along, it wasn't because physicists were sitting scratching their heads,
14
thinking there must be some deeper understanding of the nature of reality.
15
I know, let's come up with quantum mechanics.
16
It was forced on physicists because of experimental results
17
that were inexplicable it's a fuzzy probabilistic world things are never
18
behaving in one way for certain atoms can have two energies
19
at the same time electrons can be in two places at
20
the same time particles aren't discrete little lumps they can sometimes
21
behave like spread out waves of probability it's really down at a level far beyond anything
22
that we can visualize or imagine
23
if we think about everyday objects a tennis ball for example subject to the laws of newtonian mechanics.
24
You drop down orders of magnitude down to a millimetre, down to a micrometre, down to the scale of individual cells or bacteria.
25
Ultimately, when you get down to something like a billionth of a metre, then you start to encounter the fuzziness of the quantum world.
26
The founding fathers of quantum mechanics in the 1920s, people like the Danish physicist Niels Bohr, Werner Heisenberg, Wolfgang Pauli.
27
And they realized they could make predictions for the results of measurements.
28
But you only make the connection with the real world if you look.
29
So that's how they got away with not needing a narrative.
30
The shut up and calculate interpretation.
31
More correctly, it's known as the Copenhagen narrative.
32
But now, many physicists, including myself, argue that it's not a narrative at all.
33
It's a bury your head in the sand approach.
34
Einstein was very unhappy about this, by the way.
35
He said, no, look, the job of physics is to know and understand how the world is, not just to make predictions about the results of experiments,
36
that sort of operationalist view.
37
Well, fine, that's useful, but that doesn't give us real understanding.
38
That's why we still need a narrative.
39
The knowledge of quantum mechanics, together with Einstein's theories of relativity, really gave us the modern world.
40
We wouldn't have developed understanding of materials and how they conduct electricity, so we wouldn't have understood semiconductors we wouldn't have developed silicon chips,
41
therefore we wouldn't have computers.
42
I wouldn't be talking here in this medium today were it not for our quantum understanding.
43
But there are aspects of the quantum world that are more mysterious.
44
Quantum entanglement, for example, the idea that,
45
let's say, two electrons that are separated in space can nevertheless somehow behave in a coordinated way.
46
There are speculative ideas about whether space itself is connected together via quantum entanglement.
47
We don't all need to be experts in quantum mechanics.
48
Not even the smartest quantum physicist knows how stuff goes on inside their smartphone.
49
But we are going to be developing ideas like quantum cryptography, quantum computing, quantum sensors.
50
These are ideas and technologies that are going to affect us in our daily lives.
51
So we do need to have enough of an appreciation of the science simply to know what to trust, who to trust.
52
As we peel back layers of the onion about the nature of reality, we find deeper mysteries inside.
53
But it's also true that we are learning more.
54
We are becoming more enlightened.
55
We know a lot about how the world works now, but that doesn't mean we have reached the end of the road.
56
Now, I think there's going to be more weirdness coming down the line, And that's great.
57
I look forward to it.

이 영상이 영어 회화 연습에 좋은 이유
이 영상은 과학적 주제를 쉽게 풀어낸 대화체로, 자연스러운 영어 발음과 리듬을 배우기에 적합합니다. 전문 용어도 있지만 일상적인 설명이 섞여 있어 영상 영어 공부에 최적입니다. 특히 "That bugs me"나 "crank the handle" 같은 구어체 표현이 많아, 책에서 배우지 못하는 실용적인 표현을 습득할 수 있습니다.
자연스러운 표현 분석
- "The job of physics is to know and understand how the world is": "is" 대신 "works"를 쓸 수도 있지만, "is"를 사용해 더 직관적인 표현을 만듭니다. 영어에서는 "how the world is"처럼 간결하게 현실을 묘사하는 경우가 많습니다.
- "We wouldn't have developed silicon chips, therefore, we wouldn't have computers": "therefore"가 중간에 위치해 논리적 연결을 강조합니다. 구어체에서도 "so" 대신 "therefore"를 사용해 더 공식적이지만 자연스러운 말을 할 수 있습니다.
- "I look forward to it": "it"이 가리키는 내용이 앞서 언급된 "more weirdness"이지만, 문맥에서 자연스럽게 이해됩니다. 영어에서는 명확한 참조 없이도 대화가 이어지는 경우가 많으므로, 이런 패턴을 익히는 것이 중요합니다.
Shadowing 연습 방법
Shadow speech를 하기 위해선 10-15초 분량을 반복해서 듣고 따라하는 것이 좋습니다. 먼저 영상을 듣고 발음과 억양을 주의깊게 관찰한 후, 즉시 따라합니다. 녹음기를 사용해 자신의 말과 원본을 비교해 영어 발음 교정을 합니다. 하루에 10분씩坚持하면, 자연스러운 리듬과 표현을 익힐 수 있습니다. Shadowing site를 이용해 텍스트와 음성을 동시에 확인하면 더 효과적입니다.
이 영상을 통해 과학 지식뿐만 아니라 실용적인 영어 회화 기술도 쌓아보세요. 작은 부분부터 차근차근 연습하다 보면, 자연스러운 영어 표현을 마스터할 수 있습니다.
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.
