1
No, say ABC.
2
Oh little kitty, why are you teaching the alphabet to the keyboard?
3
The keyboard doesn't know ABC.
4
Look!
5
Ha ha ha!
6
Well, I know this looks like a mistake.
7
But there is a reason why the alphabets are in this order.
8
Why?
9
Let me answer that by addressing an alphabetical question.
10
Why aren't keyboards in ABC order?
11
Zoom in!
12
If you've ever glanced at the keyboard of your electronic device, you've probably noticed something strange.
13
It's not organized in the logical sequence of the alphabet.
14
Instead, it might seem like a curious mishmash of letters a seemingly random arrangement that defies the familiar ABC order.
15
But, what if I told you, they are arranged this way for a reason?
16
To know the answer, let's travel back to the 1800s, where an American inventor, Christopher Scholes,
17
was focused on perfecting a device known as a Paginator, designed to efficiently type numbers onto paper.
18
However, one fine day, his friend Carlos Gleiden brought forth a magazine featuring an article about an innovative device,
19
the Tero-Type, an advanced machine that could print alphabets onto paper.
20
Motivated by this discovery, Schultz shifted his focus toward creating his version of the machine.
21
After much effort in 1874, his invention eventually materialized as the typewriter,
22
which had the keyboard in the usual alphabetical order.
23
Excited by this, Schultz handed his invention for testing to telegraph operators,
24
who required swift transcription of messages from Morse code.
25
However, while using this new machine, the operators found the alphabetical layout quite confusing.
26
More importantly, the faster someone typed, the more frequently the typewriter jammed,
27
particularly when the keys were closely positioned on the keyboard.
28
He took this feedback seriously and experimented with various arrangements aiming to minimize the necessity of typing closely positioned keys.
29
After numerous trials and errors, he arrived at the best arrangement known as the QWERTY keyboard,
30
which remains in common use today.
31
Just look at the top row of a keyboard to understand why it's called QWERTY.
32
Later, Scholz sold his invention to the Remington company,
33
which manufactured and marketed the first commercially successful typewriters featuring the QWERTY keyboard.
34
Following this, numerous people worldwide learned to type proficiently on this keyboard,
35
opening up abundant job opportunities for them.
36
So despite several other options coming into the market, like the Vorac keyboard layout designed to put less stress on the typist's hands,
37
most people found it hard to switch to a different keyboard
38
layout as they were already trained to use the QWERTY keyboard layout by that time.
39
And this familiarity is the reason that later on, even computers and smartphones retained in the QWERTY layout.
40
This proves that sometimes what seems most logical isn't what everyone ends up using.
41
People stick to what they know and what works best for them.
42
So we can say that a change made due to the jamming of keys is stuck with us forever.
43
Trivia time!
44
Did you know that thousands of English words can be spelled using only the left hand?
45
While only a couple of hundred words can be typed using only the right hand
46
also typewriter proprietor perpetuity and repertoire are the longest English words that can be written
47
using only the keys in the top row It's sketching time Today's sketch of the day goes to VEDHA!
48
Hope you learnt something new today.
49
Until next time, it's me, Dr. Binox, zooming out!
50
Oh, what are you doing, Kitty?
51
Making a keyboard.
52
And what is it called?
53
Kitty Keyboard!
54
Ha ha ha!
55
Never mind!
56
Thank you.

練習のヒント

このビデオのスピードやトーンで効果的に学ぶためには、shadowspeakやshadow speakを利用して発音練習を行いましょう。特に、ビデオの内容を繰り返し聞きながら、自分の声を録音してみると良いでしょう。録音した自分の発音を確認することで、どの部分がうまくできているか、また改善すべき点について理解が深まります。

また、IELTS スピーキング対策として、特にQWERTY配列に関する語彙を使った短いスピーチを練習することをお勧めします。発音を意識しながら、リズムや抑揚をつけることで、より自然な英語を話すことができるようになります。定期的にこの練習を行うことで、英語の発音を良くするための自信がつき、コミュニケーション能力が向上します。

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。
