Dr. STONE (Dr.STONE)

What do you know?

So the Corn City folks are going to help us make circuit diagrams.

Free manual labor.

I don't know what those two are cooking up,

but they sure look excited, don't they?

Oh, I know.

The Stone World is finally getting smart phones.

Haven't heard that one in a while.

You really miss screen time, huh?

Sorry, still no dice.

We'll just be wrapping coils for the computer.

We're taking this step by step.

Truly, proper craftsmanship from those three.

Why are we wasting my raw manpower

sitting around making tiny little coil thingies?

We'll need to get to the moon and land there.

It's like getting a hole in one on the first try, but on a cosmic level.

We're going to need a way to do precise calculations.

So the Stone World desperately needs a computer.

Do you realize you sound like a mad scientist?

There's no freaking way.

STONE WORLD MATH OLYMPICS

The Math Olympics, and tools aren't against the rules?

That sounds fun.

Feels like Gen's way of motivating us to make calculators.

Please, we're not a bunch of stupid kids.

They can't trick us into helping them with some bogus competition.

It says here that the winning team gets 100 million drago.

THE TRUTH ABOUT THE ROCKET

Listen up, we'll need all hands on deck for this one.

We're making memory.

Memory?

For computing.

We need storage devices.

Without them, our machine won't be able to remember any numbers, much less

pull off complex calculations.

Circuits for thinking and for remembering.

Then we just have to combine the two,

and computational wizardry is at our fingertips.

Say that again.

Machines can remember things?

I don't get it.

To be fair, nor do I.

How do you expect us to pull this off without semiconductors?

We'll be saving our data onto magnets.

Oh, wow.

Senku's faxing us instructions on crafting memory.

It's still going.

Run a strong current through oxidized wires.

When the process is finished

you've got a magnet.

We can also run the current backwards.

One side becomes north, and the other south,

determined by the digit it's storing.

In short, each magnet stores a number,

and it's either a 1 or a 0.

That's pathetic.

It just knows 1 or 0?

Any idiot could do that math.

What a waste.

Why bother going through all the trouble?

You're oversimplifying.

Memorizing one number wouldn't be impressive,

but imagine putting lots of them together.

Watch and learn.

To save on this little magnet,

I zapped the third column

and the second row.

That's how it remembers.

Oh, I get it now.

Only the point where the two wires cross gets a bad shock.

That's how it knows which side is north.

And it remembers that without affecting the other magnets.

Yep. You just earned a cool 10 billion points.

It's ridiculously primitive, but reliable as hell.

The space shuttle and F-15 fighters use this method.

It was a group effort, to say the least.

They had skilled tailors working non-stop to make everything they needed.

What you're saying is that our current mission is to sew together a ton of these tiny magnets we made.

Exactly how much is a ton, anyway?

Didn't he say it'd be something like 200,000?

Is that all we need?

That's nothing for a capable woman.

Oh, that is what he said.

But that was only for the donuts.

Thank goodness.

But that didn't worry me.

As for the magnets, he says we need...

just 30 million or so.

There's more we need to do with these?

Vertical and horizontal wires write the data.

Now we need to add in diagonal wires.

That's the only way that we can read it.

We still need something to view the numbers, like a display.

So we're using Nixie tubes.

We'll place wire numbers and tubes of gas.

Then they'll light up when we run a current through them.

You can leave the precision work to the master craftsmen.

Compared to crafting fine watches,

it's as simple as taking candy from a baby.

We're all good on fuel thanks to India.

Then it's finally time to set sail.

Let the games begin.

Is everyone eady-ray?

It's the Indian Ocean New World Math Olympics.

Not to be mean, but it seems like Gen finally snapped.

Say hello to our contestants,

Chrome, Senku, and Sai.

Chrome's up there?

But he has no chance of winning against those other two.

That's not all.

Joining us remotely from Corn City, it's Magma.

Magma?

Why did we pick Magma?

No one could be worse at number stuff than him.

That is precisely why we chose him.

He's no less than ideal.

Now it's a race to solve this equation.

Wait, what? That's bad!

8 then 2, 7, 4, and 0.

Then 1 and 1 and 3 and 6, 0, and 5 and 8.

Yep.

He got it.

He even managed to beat a genius like Senku,

and all within the blink of an eye.

So that's the true power of a computer.

We got to bear witness.

That was another defining moment for all of humanity.

Incredible.

We did it.

It's a Stone World computer.

Yeah.

Something that humans made from scratch

is capable of transcending the human mind.

This is exhilarating.

Get excited.

CALCULATOR ACQUIRED!!

You stuffed 30 million magnets into that thing?

Try to think before you talk.

It's just a few thousand.

No way.

So the next one's going to be even more impressive?

Smartphones, let's go!

That's quite the workload.

This won't be easy.

We won a lot of drago in that contest,

but it's more like a commission for work.

Hey, where's the cash?

We won 100 million drago fair and square.

Explain yourself, Ryusui.

No need to worry.

We will credit your account.

Ryusui Bank is open for business.

Are you trying to weasel out of this?

You expect us to believe that?

But banking isn't that simple.

How will you record and calculate balances?

BANKING ACQUIRED!!

Status report.

Xeno's got the engine covered.

And Yazuriha's team is crafting the computer parts.

As for our contribution, we'll make the actual rocket,

and finally blast off to the moon.

The rocket, huh?

You're talking about the part where the people will go?

What's it going to be made of?

I'm guessing iron, right?

Iron's way too heavy to launch all the way into space.

We'll use aluminum, because that stuff is stupidly lightweight.

Time to leave the shores of India

for the next stop on our adventure,

the land down under, Australia.

We'll be going right to the tippy top.

That's where the world's most abundant source of bauxite is waiting for us.

It's the ore we'll use to make our aluminum.

Right. Leave the rock hunting to the resource king.

Between a pro explorer like me and a pro geographer like Chelsea, we're set.
