1
And, it's complete!
2
Oh! You're back.
3
I've missed you.
4
So, what do you think of my new collection of Numbers!
5
Something is missing?
6
That's impossible.
7
Everything's here. There's nothing missing.
8
Oh, wait. Now I see.
9
You are talking about the number that denotes nothing.
10
You are talking about the number Zero! Right?
11
So, let's zero in!
12
Oh, sorry. I mean, zooom in.
13
Don't you wonder why the number zero is so important in mathematics?
14
When it only means nothing?
15
Well kids, it because of the two very different and very important purposes..
16
..that zero serves.
17
Firstly, it's Zero that separates the negative numbers from the positives.
18
Secondly, it serves as a place holder for writing numbers.
19
Consider the number 10 for example.
20
It has two parts.
21
1 and 0. The number zero is placed here to say,..
22
..that it is 10 times bigger than the number 1!
23
However, people from ancient times could not wrap their heads around the idea..
24
..of denoting nothing, by something.
25
So, they never considered zero as a number.
26
Consider this man, for example.
27
Excuse me, Sir.
28
Will you please tell me how many sheep you have now?
29
I don't have even 1 sheep.
30
You see, people were able to communicate the idea of nothingness...
31
Uh.. One minute, Sir.
32
But they did not have a representation for it.
33
What is it?
34
My sheep. Oh, yes of course. I'm sorry.
35
Here you go.
36
It was not until 628 AD..
37
..that zero became an important part of the number system, in East India.
38
An Indian Astronomer and Mathematician, Brahmagupta..
39
..took the idea of nothingness...
40
Symbolized it with a dot.
41
And, included it in the number system.
42
This was the first time in the whole world..
43
..that zero was included in the number club.
44
Hey, hold on.
45
Wait a minute.
46
Not so fast, with your celebrations there, peeps.
47
Although, Brahmagupta gave us the rules for using zero in calculations..
48
..defining it's very first important use.
49
He never introduced zero for it's second purpose.
50
That is, as a place holder digit.
51
It was another Indian mathematician, Aryabhata.
52
Who gave rules to use zero as a place holder.
53
This helped representing numbers like 10, with 1 and 0.
54
Instead of coming up with a whole new symbol for them.
55
Thanks to these mathematicians for nothing!
56
I mean zero.
57
Soon this revolutionary knowledge spread around the whole world.
58
And, mathematicians across the globe started using it in their calculations.
59
Today, zero also forms an integral part of Physics, Chemistry..
60
..Astronomy and Computer Science too.
61
Welcome, Welcome.
62
We have been waiting for you all.
63
Our family of numbers with the hero, Zero.
64
So now, let's look at some of his properties.
65
When the integers are placed on a number line..
66
..number 0 places itself before number 1.
67
The number 0 is neither negative nor positive.
68
It's a natural number.
69
Come friends, let's take this Zero back to our number collection.
70
Oh, look at this.
71
Isn't our Zero looking beautiful?
72
What? No way. Something is missing again?
73
1..2..3..4... Oh! I see, I remember.
74
TRIVIA TIME!
75
There is a large number called Googol.
76
That is written as 1 followed by a hundred zeros.
77
And do you know who coined it?
78
Someone just like you.
79
Googol. Milton Sirotta, the 9 year old nephew of US mathematician Edward Kasner..
80
..came up with the term Googol.
81
That's a lot of zeros, isn't it?
82
But wait till you hear about Googol Plex.
83
Which is 1 followed by 1 googol zeros.
84
Even Google could not have found me there.
85
Wait. Doesn't Google sound like Googol?
86
It does! And that's because the popular search engine derived it's name from the number Googol.
87
And that my friend, is the story of number zero.
88
So kids, I hope you learnt something interesting today.
89
To know more about such cool inventions, tune in next time.
90
This is me zoooming out.
91
Hey, kids. You liked my videos, didn't you?
92
Before you go, don't forget to click on the subscribe button and the bell.
93
So you won't miss out on my latest videos.
94
See you.

背景介绍

在这一集的《Dr. Binocs Show》中，主持人通过生动的讲述引导观众探索数字“零”的重要性。虽然零代表着“无”，但它实际上在数学中扮演着不可或缺的角色。从历史上看，古代人对于如何表示“没有”这一概念感到困惑，直到印度数学家Brahmagupta在公元628年提出了零的概念。通过这样一个简单却深刻的主题，孩子们不仅可以学习数字的基础知识，还可以认识到科学和数学思想发展的历程。

日常交流中的五个常用短语

  • I'm sorry. - 对不起。
  • How many do you have? - 你有多少个？
  • I don't have even one. - 我甚至没有一个。
  • What is it? - 那是什么？
  • Here you go. - 给你。

这些短语在日常生活中非常实用，可以帮助英语学习者应对各种交流场合。使用这些短语时，可以尝试结合英语影子跟读技术，增强自己的口语能力。

逐步影子跟读指南

为了有效学习并处理这段视频的内容，我们可以按照以下步骤进行影子跟读：

  1. 观看视频：首先观看整段视频，理解其整体内容和语调。
  2. 逐句跟读：将视频暂停，每次只播放一小段，模仿发音和语调。用shadowspeak的方法重复每句话，注意语音的抑扬顿挫。
  3. 重听核对：重复这一步骤后，回过头去重听并对照自己的发音，看看和原音有哪些差异。
  4. 运用练习：尝试将学习到的短语应用到不同的场合，例如与朋友交流或在模拟对话中。
  5. 定期复习：在接下来的日子里，每周至少回顾和练习这些短语几次，以增强记忆和口语流利度。

通过这套逐步的影子跟读方法，英语学习者能够更好地掌握发音和语调，提升整体口语能力，尤其是在雅思口语练习中，能够更加自信地运用所学内容。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
