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.

पहली छापें
इस वीडियो में, भौतिकी के विषय में एक गहरी चर्चा की गई है, जिसमें अंग्रेजी बोलने का अभ्यास करने के लिए बेहतरीन सामग्री है। यहाँ पर विज्ञान की अवधारणाओं को सरल भाषा में समझाया गया है, जिससे श्रोतागण इन्हें आसानी से समझ सकें। संवाद में विचारशीलता और जिज्ञासा है, जो इसे दिलचस्प बनाती है। वीडियो में वैज्ञानिकों की चुनौतियों और खोजों के बारे में बात की गई है, जो सुनने वालों को प्रेरित करती है।
इसे तोड़ें
वीडियो में कुछ वाक्य विशेष रूप से प्राकृतिक सुनाई देते हैं। उदाहरण के लिए, "यह एक धुंधला, सांयोगिक विश्व है।" इस वाक्य में शैडोइंग तकनीक का उपयोग करते समय, आपको शब्दों के बीच के भाव को समझना जरूरी है। यह एक सामान्य धारणा को स्पष्ट करता है कि क्वांटम भौतिकी की दुनिया कितनी जटिल है। इसी तरह, "कण कभी-कभी संभाव्यता की फैलाव वाली लहरों की तरह व्यवहार कर सकते हैं।" यहाँ पर 'कण' और 'संभाव्यता' जैसे शब्दों का सही उच्चारण और रिदम सुनने में बेहद मददगार होते हैं।
अभ्यास दिनचर्या
आप इस वीडियो के संवाद को वीडियो से अंग्रेजी सीखें के लिए एक अभ्यास के रूप में उपयोग कर सकते हैं। यहाँ एक साधारण दोहराने और रिकॉर्ड करने की प्रक्रिया दी गई है:
- वीडियो को एक बार सुनें और उसकी सामग्री को समझें।
- अब, वीडियो के छोटे हिस्सों को सुनें और उन हिस्सों को दोहराएँ।
- अपने उच्चारण और रिदम का अभ्यास करते हुए रिकॉर्ड करें।
- फिर अपनी रिकॉर्डिंग सुनें और सुधार के लिए नोट्स बनाएं।
इस प्रक्रिया से आप न केवल अपने बोलने के कौशल को सुधारेंगे, बल्कि वैज्ञानिक विचारों को भी समझेंगे। याद रखें, shadowspeaks तकनीक का उपयोग करते हुए, हर बार जब आप अभ्यास करते हैं, तो आप अधिक आत्मविश्वास और स्पष्टता के साथ अंग्रेजी बोलने में सक्षम होंगे।
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
