Koko:
Owlo, look at what I found today in the school playground! It's a secret note with strange symbols on it.
Owlo:
That's very interesting, Koko, let me take a look. This really looks like some kind of secret code.
Koko:
Yes, that's exactly what I thought it was! My friend Jasper and I sometimes send each other secret messages. But I don't really understand this particular code.
Owlo:
You know, code breaking has been very important in history. Shall we go to the library together? I want to show you something interesting.
Koko:
Wow, look at all these books about secrets and codes! What are we looking for, Owlo?
Owlo:
I want to tell you about a very special man. His name was Alan Turing, and he was a brilliant mathematician from England.
Koko:
What does brilliant mean, Owlo? Does that mean he was very smart?
Owlo:
Exactly right, Koko, that's what it means. Brilliant means super smart and very creative. Alan Turing lived about eighty years ago.
Koko:
What did he do with his life? Did he make puzzles like this one here?
Owlo:
He did something even more important than that. During World War Two, the enemies made secret codes. Alan Turing helped crack those codes.
Koko:
Wow, so he could read all their secret messages? Just like I try to read Jasper's codes?
Owlo:
Yes, but his codes were much harder to crack. The enemies used a special machine called Enigma. It made very many different codes.
Koko:
How did he crack such a difficult code then?
Owlo:
Alan Turing built a special machine that could think cleverly. That machine was called the Bombe, and it could find patterns in the codes.
Koko:
A machine that could actually think? That sounds like magic to me!
Owlo:
It wasn't magic, but it was very clever mathematics. Turing thought of ways that machines could solve problems.
Koko:
Do we use those kinds of machines now too?
Owlo:
Absolutely, we use them every day, Koko! Alan Turing is often called the father of the computer. Without his ideas, we wouldn't have computers now.
Koko:
Wow, that's amazing! So my tablet and mama's laptop exist because of him?
Owlo:
Indeed, that's right, Koko. He thought of how machines could follow instructions and solve problems. That's exactly what computers do every day.
Koko:
That's really cool, Owlo. Did he help many people by cracking those codes?
Owlo:
Yes, he helped very many people, Koko. Experts think his work may have made the war two years shorter. That saved very many lives.
Koko:
That makes him a real hero! Did he get a big party for that?
Owlo:
Sadly not right away, Koko. His work was secret for many years after the war. Only later did people show respect for what he did.
Koko:
That's so sad, Owlo. I think heroes should be celebrated right away.
Owlo:
You're completely right about that, Koko. Now we all know how important he was. There are even films made about him.
Koko:
Owlo, can I also learn about codes and computers? Maybe I can make something special later too!
Owlo:
Of course you can, Koko! Smart ideas and hard work can change the world. Just like Alan Turing did with his work.
Koko:
So Alan Turing was a super smart mathematician who cracked secret codes. He built special machines that could think and solve problems.
Koko:
Because of him, we now have computers and tablets today. He saved very many people during the war. I want to learn more about codes and computers!
Owlo:
That's a beautiful summary, Koko, well done. Maybe we can make a simple code together next week for you and Jasper.
Koko:
Yes, I would love that very much! And then I'll tell him about Alan Turing. Thank you so much, Owlo!
