Shadowing Practice: 🔥 Elon Musk: This Engine Produces More Thrust Than 4 Boeing 747 Engines #joerogan #shorts - Learn English Speaking with Video

Creating lesson...
1
It'll be about 30 times faster than a bullet from a handgun.
2
30 times faster than a bullet from a handgun and it's the size of a skyscraper.
3
Yes.
4
Yeah.
5
That's fast.
6
It's so wild!
7
It's so wild to see, man.
8
It's so exciting.
9
The factory is so exciting too, because like genuinely, no bullshit, I felt like I was witnessing history and the sheer numbers of them that you guys are making.
10
And then this is a version and you have a new updated version that's coming soon.
11
And what is the difference?
12
It's a little longer.
13
More pointy?
14
It's the same amount of pointy, but it's got a bit more length.
15
The interstage, you see that interstage section with the grill area?
16
That's now integrated with the boost stage.
17
So we do what's called hot staging, where we light the ship engines while it's still attached to the booster.
18
The booster engines are still thrusting, it's still being pushed forward by the booster of the ship.
19
But then we light the ship engines and the ship engines actually pull away from the booster, even though the booster engines are still firing.
20
Whoa!
21
So it's blasting flame through that grill section, where we integrate that grill section into the boost stage with the next version of the rocket.
22
And the next version of the rocket will have the Raptor 3 engines, which are a huge improvement.
23
You may have seen them in the lobby, because we've got the Raptor 1, 2, and 3.
24
you can see the dramatic improvement in simplicity.
25
We should probably put a plaque there to also show how much we reduced the weight, the cost, and improve the efficiency and the thrust.
26
So the Raptor 3 has almost twice the thrust of Raptor 1.
27
Wow.
28
So you see Raptor 3, it looks like it's got parts missing.
29
It's very, very clean.
30
How many of them are on the rocket?
31
There's 33 on the booster.
32
And each Raptor engine is producing twice as much thrust as all four engines on a 747.
33
Wow.
34
So that engine is smaller than a 747 engine, but is producing almost 10 times the thrust of a 747 engine.
35
So extremely high power to weight ratio.
36
So when you're designing these, you get to Raptor 1, you see its efficiency, you see where you can improve it, you get to Raptor 2.
37
How far can you scale this up with just the same sort of technology, with propellant and ignition and engines?
38
Like how much further can you?
39
We're pushing the limits of physics here.
40
So really, in order to make a fully reusable orbital rocket, which no one has succeeded in doing yet, including us, but Starship is the first time
41
that there is a design for a rocket where full and rapid reusability is actually possible.
42
So it was not, there's not even been a design before where it was possible.
43
So we live on a planet where the gravity is quite high, like Earth's gravity is quite high.
44
If the gravity was even 10 or 20 percent higher, we'd be stuck on Earth forever.
45
We could not use, certainly couldn't use conventional rockets.
46
On the other hand, if Earth's gravity was just a little lower, like even 10-20% lower, then getting to orbit would be easy.
47
It's like if this was a video game, it's set to like maximum difficulty, but not impossible.

About This Lesson

In this lesson, learners will practice English by listening to and mimicking a segment from an engaging discussion featuring Elon Musk. The focus will be on understanding complex engineering concepts expressed in everyday language, while also improving pronunciation and fluency through the practice of shadowing. By the end of this lesson, you will feel more comfortable with technical vocabulary and be able to engage in conversations about advancements in technology.

Key Vocabulary & Phrases

  • Thrust: The force that propels an object forward; important in discussions about rockets and engines.
  • Booster: A component of a rocket that provides the initial thrust needed to launch it into space.
  • Hot staging: A method where a rocket's engines are ignited while still attached to the booster, allowing for smoother transitions in launch sequences.
  • Efficiency: A measure of how well a process converts inputs into outputs, often used in the context of engines or machinery.
  • Propellant: The fuel used by rockets and engines to produce thrust.
  • Power-to-weight ratio: A key performance metric indicating the power of an engine relative to its weight.
  • Fully reusable: Refers to technology designed to be used multiple times without significant refurbishment, a critical aspect of modern space travel.
  • Gravity: The force that pulls objects toward the Earth; understanding its effects is crucial in discussions surrounding space exploration.

Practice Tips

To get the most out of this lesson, utilize the shadowing technique. As you watch the clip, listen to Elon Musk's speech patterns, intonation, and pacing. Begin by playing the video in short segments. Repeat each segment out loud immediately after hearing it. This method can significantly enhance your English pronunciation and help you internalize the natural flow of conversation.

Pay attention to Musk's emphasis on specific words, particularly technical jargon, as this will aid in building your vocabulary in a contextual manner. Aim to match his speed, but don't rush; clarity is key. You can adjust the playback speed on the YouTube video to a comfortable pace if needed. The shadowing site refers to the concept of repeating after a speaker, which is beneficial for language acquisition.

Engaging with this video will help you not only to improve your English speaking skills but also to familiarize yourself with discussions on technology and engineering. Consider revisiting the video multiple times, gradually increasing your speaking pace as you grow more confident. By incorporating this practice into your routine, you will find it easier to discuss complex subjects in English.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
