1
Five fun physics phenomena.
2
Number one: Have a friend hold a cane out horizontally for you or another similar object,
3
and putting your two index fingers together try to place them underneath the center of mass.
4
When they let go, you will find it doesn't normally work.
5
But, Now try putting each index finger at opposite ends of the cane, and then moving your index fingers in towards the middle.
6
what you will find is that they always end up right under the center of mass of the cane.
7
You can try starting off asymmetrically.
8
and they will still end up under the center of mass.
9
You can try going at different speeds really slowly.
10
you Or really fast?
11
but you still end up perfectly under the center of mass.
12
How does this work?
13
Number two: The Phone Flip.
14
Have you ever tried to spin your phone?
15
If you do it in this direction, it's pretty easy.
16
It stays nicely aligned.
17
If you spin it along its short axis, you'll also find it spins very well.
18
But, if you try to flip your phone end over end like this, you can't do it cleanly.
19
The phone will never flip simply end over end without also rotating in one of the other directions.
20
Even when I make an almost perfect flip, instabilities grow until the phone rotates around another axis.
21
Why can't...
22
No, I still can't do it.
23
Why is it so?
24
Number three.
25
You've probably seen that if you rub a cup on your hair, you can make it electrically charged, and if you bring it close to a stream of water,
26
you can actually cause that stream to deflect.
27
Now usually this is used in chemistry textbooks as a demonstration of the polar nature of water.
28
Water is a molecule with a more positive side and a more negative side.
29
And so what happens, so you're told, is that the water molecule flips around
30
so the positive side of the water faces the negative side of the cup
31
and that is what attracts the water to the cup.
32
But this is not the real explanation.
33
If you have a uniform electric field, there's an equal force pulling the positive side towards it as there is pushing the negative side away from it.
34
And so you can't actually do more than just turn the molecules.
35
you would need a really, really strong gradient in your electric field to make this work at all
36
and it basically is just not going to happen from a cup.
37
So why is the stream actually attracted to a charged cup?
38
That is the question.
39
Number 4 Take a piece of your favorite cereal and drop it into a bowl of water.
40
Then, using a very strong magnet, try to pull the cereal around.
41
Bye.
42
Isn't that cool?
43
So why is cereal magnetic?
44
And finally, five: the teabag rocket.
45
Take a tea bag and cut off the sealed end very carefully.
46
Now dump out the tea.
47
Form the tea bag into a square column.
48
and balance it on the plate.
49
Now, light the top of the teabag on fire.
50
Try to light it evenly on all sides.
51
Get ready for takeoff in three, two, one.
52
Ha, yeah!
53
That is the beauty of the T -Bag Rocket.
54
So why did that happen?
55
So how do all of these phenomena work?
56
Let me know in the comments, or make a video explaining any or all of them, or subscribe to the channel, and I'll post the answers next week.
57
I hope you enjoyed those fun physics phenomena.
58
I know a guy who would, the former commander of the International Space Station, Commander Chris Hatfield.
59
I'm actually hosting live events with him in late August in Sydney and Canberra.
60
I am so looking forward to that.
61
Now the Sydney shows are all sold out, but there are still, as of now, tickets to the Canberra show.
62
So if you want to come to that, check out the link in the description.
63
Now Chris Hatfield actually wrote a book called "An Astronaut's Guide to Life on Earth."
64
people who want to become astronauts but also for everyone who wants to lead a meaningful life here on Earth.
65
And you can download this book for free
66
if you like by going to audible .com /veritasium
67
or you can pick any other book of your choosing for a one -month free trial.
68
Audible is a great service with over a hundred and fifty thousand titles in all areas of literature including fiction, nonfiction, and periodicals and so you can find virtually anything you want there
69
and by going to audible .com /veritasium they know that I sent you videos for you for free.
70
So I really want to thank Audible for supporting me and I want to thank you for watching.

  • “sh” और “zh” की ध्वनियाँ: explanation /ˌɛkspləˈneɪʃən/, fiction /ˈfɪkʃən/, demonstration /dɛmənˈstɹeɪʃən/
  • लंबे शब्द — बलाघात सही रखें: phenomenon /fəˈnɒm.ɪ.nən/, explanation /ˌɛkspləˈneɪʃən/, virtually /ˈvɚ.t͡ʃə.wə.li/, demonstration /dɛmənˈstɹeɪʃən/, instability /ɪnstəˈbɪlɪti/

इस वीडियो से अभ्यास कैसे करें

  1. पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
  2. 0.75× गति से शुरू करें, एक-एक वाक्य की शैडोइंग करें, और सहज लगने पर सामान्य गति पर लौटें।
  3. अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर finger, phenomenon, cane जैसे शब्दों पर ध्यान दें।

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।
