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?

93
So you won't miss out on my latest videos.
94

このレッスンについて

このレッスンでは、「ゼロ」の発明に関する興味深いお話を通じて、英語のリスニングとスピーキングを練習します。このビデオでは、ゼロが数学でどれほど重要であるか、そしてその歴史的背景について学ぶことができます。また、発音やフレーズの使い方を理解し、英語の発音を良くするためのスキルを向上させる機会にもなります。

主な語彙とフレーズ

  • ゼロ (Zero) - 何もないことを示す数字
  • 負の数 (Negative numbers) - ゼロ以下の数
  • 正の数 (Positive numbers) - ゼロ以上の数

  • コミュニケート (Communicate) - 意思や情報を伝えること

練習のヒント

このビデオを利用して、英語シャドーイングを行うことが効果的です。話者のスピードは比較的ゆっくりで、はっきりとした発音が特徴ですので、初心者でも挑戦しやすいです。まずは以下の手順を試してみましょう：

  • 繰り返し聞く： ビデオを何度も見て、内容を理解します。理解できるまで何度でも再生してみましょう。
  • 音声を真似る： 各文を聞いた後に、自分でも声に出して真似してみてください。特に語尾や強調された部分を意識して発音します。
  • 発音をチェックする： 自分の声を録音して聞いてみましょう。ネイティブスピーカーの発音と比較することで、どの部分を改善する必要があるかを確認できます。
  • フレーズを使ってみる： 学んだフレーズを日常的に使う練習をし、自信を持って英語を話せるようにしましょう。特に「ゼロ」や「計算」などの専門用語を覚えることが重要です。

英語スピーキング練習においては、言葉の意味を理解するだけでなく、実際に使用することが重要です。このビデオを通して、英語力を高め、IELTS スピーキング対策にも役立ててください。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
