What's so mysterious about this three-dimensional world?
Climbing, climbing, climbing, climbing...
What?
I can't do it.
Tonight's Madabu-kun is the mystery of the blind.
The world of impossible illusions.
It's possible.
He is very interested in the illusions that change shape one after another.
I like it.
Be careful.
Please make it.
The special lecture this time is by Kouhitsu Sugihara.
He is a professor who studies various three- dimensional illusions using the formula of mathematical theory.
He won the Grand Prix twice at the Best Illusion Contest, which determines the best illusion in the world.
He is a specialist of the illusion world who won the 10th Grand Prix twice.
First of all, I would like to show you the work of the illusion world who won the 10th Grand Prix in 2016.
I'm really surprised.
Please.
First of all, please look at this.
Yes.
What can you see?
It's a square.
Yes.
You can see a lot of squares.
What do you think it looks like in the mirror?
What do you think it looks like?
It's a triangle.
Triangle.
I see.
A circle.
It's a full circle, isn't it?
Why do you think it's a triangle?
It's too early to be mistaken.
It's a full circle.
Make it a full circle.
But it's normal if it's reflected in the mirror.
It's reflected as it is, isn't it?
Now, this is the teacher.
Yes, I'll count this one.
Please look at the mirror in the back.
What? Really? This is just reflected in the mirror, isn't it, teacher?
That's right. It's just a normal plane.
There are two of them.
Why? Why?
This is just reflected in the mirror, isn't it?
That's right. It's just a normal mirror.
Can you move it a little bit, teacher?
That's right. Your hand should also be reflected in the mirror.
Yes, your hand should also be reflected in the mirror.
I'll move this.
What?
Why? Why?
This is just a normal plane.
What? Really?
Why? What do you mean?
I'll do it again.
Why? Why?
This is just reflected in the mirror, isn't it?
Why? Why?
This is just reflected in the mirror, isn't it?
Why? Why?
This is just reflected in the mirror, isn't it?
This is just a normal plane.
When this three-dimensional object, which can only be seen in the parallelogram, is reflected in the mirror,
For some reason, in a circle,
What the hell is going on?
I think it's good to see the real thing.
In fact, it is a shape of the middle that is neither a circle nor a square.
If you look at it from a certain direction, it looks like a circle, and if you look at it from the other side, it looks like a square.
When you look down at about 40 degrees, it looks like a square.
So it's actually like this.
I don't really know what this is.
What is this shape?
Great!
So it's not a square that was shown at the beginning.
This is the Jun Grand Prix.
Yes, that's right.
It wasn't a Grand Prix.
Unfortunately.
No, no, it's strange.
This is the Grand Prix.
I'll go.
It's nothing.
You don't know anything about this tournament.
I don't know anything.
It's amazing.
By the way, why does it look like that?
Our brain loves simple shapes like circles and squares.
When I see a shape that looks like it, I think so.
This three-dimensional is actually a complicated curve where the upper end goes up and down.
If you look at it from a certain direction, it looks like a circle, and as soon as you look at it, you feel like you're looking at a cut that's stuck on the plane.
It's strange, isn't it?
In everyday life, there are many round and square things.
Therefore, when we look at a human brain in a shape similar to a circle or a square, we judge only by the characteristics of the plane, and if it is a circle or a square, it causes an illusion.
In addition, the teacher is doing a three- dimensional research using the equation of mathematical engineering to cause this kind of illusion, so it's not like making it, it's too complicated and I don't think it can be done by trial and error.
If you solve the equation, you will automatically get this kind of shape.
Is there an equation?
People who are far away.
How far are you from yourself?
How do you see it? Saktaku Quiz!
First of all, let's learn from the basics of the teacher's three-dimensional illusion.
First of all, here!
This is an ordinary three-dimensional illusion.
A bird is drawn here.
A horizontal bar, a yellow bar, and a vertical red pillar.
Which one looks longer?
This is a pillar.
It's definitely red.
I see.
It looks like that, doesn't it?
Teacher, what's the correct answer?
Actually, it's the same length.
This is...
No way.
They look the same.
I'll measure it.
From here...
It's easier to measure from here.
Yes, from the middle.
It's definitely...
It's the same.
No matter how you look at it, the red one looks longer.
That's right.
If you move the vertical bar to the side, it looks like this.
I'm totally with you. It's a cicada. Let's get some cicadas. In fact, cicadas are the same length. Not at all. Really? This is an illusion. What kind of illusion is this? This illusion has a name, doesn't it?
It's called quick lyric writing. sticks of the same length. Quick lyric, yes.
If you connect it vertically and horizontally like the letter T, it looks longer vertically.
It looks like that with my fingers too.
With your fingers too?
With my fingers too.
With your fingers?
But that's a bit...
It looks longer vertically.
That's right.
Let's move on to the next question.
This is an illustration of a building. Teacher, what is this picture?
First of all, I want you to sketch how it looks like.
Is there anyone who is good at drawing?
Let's have Uuka sketch this picture.
First of all, let's have Uuka sketch this picture of the building as it is.
I've only sketched a little bit.
Yes.
Oh, I see.
You can see the lines with your second eye, right?
I think the walls of the building are slanted diagonally.
But this is actually straight, isn't it? yeah yeah yeah yeah yeah yeah yeah yeah
yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah
yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah
yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah yeah founder
satisfied with
with
If you try to move only the black square at a distance, the horizontal line that should be parallel looks distorted.
Next is a quiz with these two
Which is longer, the torso or the wings?
The torso is longer on the left
The wings are longer on the right
I see
Sensei, how about this one?
It's the same
It's exactly the same
Both the torso and the wings
If you erase the thickness and leave only the red part of the torso and the yellow part of the wings, you can see that they are the same
If you add the thickness, you can see that they are the same
If there is the thickness, the brain recognizes it and corrects the thickness
It means that if there is the thickness, you can feel the thickness for a long time
That's right
It is not yet clear why each illusion looks like this
After learning various illusions, the next is
Let's learn Mr. Sugihara's original three- dimensional work
There are several stages in the three-dimensional work that you have created
Let's take a look at them step by step
First of all, this one
Mr. Sugihara's original three-dimensional work
Is it strange?
Yes, please tell me where it is strange.
Then, let's have someone come out and climb the stairs more and more.
Yes, someone who will do it for me.
Shu.
Shu, please come out.
How do you climb?
I'll come out now.
No, actually on the screen.
Yes, please climb.
Climb here.
Climb up, climb up, climb up.
You are right. If you keep climbing, you'll go back to your original position.
Oh, but I can go down!
You can go down?
You can go down? What do you mean?
You can go down?
I can go down, go down, go down, go down, go down, go down, go down.
I can go up further.
Maybe you are too talented.
What do you mean?
What?
Even if you keep going down...
never ending. There is no end even if you keep climbing. Really! Sensi is amazing!
That's right! That's right. It's really impossible.
Originally there was a soul picture, which is said to be a picture of impossible solids.
A picture of the Hangan family in Holland is a famous picture used for Hangan.
Would you like me to show you the actual product? I found out that it can be made as a three-dimensional object.
This is the solid. These three sides of the wall of the building are ordinary stairs,
It's on the fourth wall.
The shape is a slanted slanting structure, and when you look at it from a particular direction, this line and this line look parallel, and this is diagonal, but this line and this line are parallel. I've taken a picture from the position where I can see it, so my brain, which loves squares and right angles, thinks that this is also an ordinary staircase made of horizontal and vertical lines.
There are many other things, sir. Yes, here.
I'll try to figure out what's wrong with this too. This is disgusting. That's amazing.
Why? You know what's wrong with this? can anyone explain?
Even though this is how it is, it is lying down again.
The left wall is lined up horizontally and pierced through, while the right wall is lined up vertically and pierced through.
that's strange.
here again on the bridge
Why?
This is also a fake picture. Not at all.
That's amazing.
This horizontal plate is a parallelogram. not a rectangle.
When the camera positions are aligned, the gap in the middle appears to be the same width.
As a result, the parallelogram and the brain feel like a rectangle.
So even in this real thing, if you look at it from a certain angle, it looks like this, right?
Yes, that's right.
From there, I think it's like this.
Wow, amazing!
I want to go there!
Can I go there?
I want to go there!
Can I go there?
Turn around from here and look at me.
Oh!
Amazing!
If you want to see this, come here.
Come here.
This angle.
Come here while looking at this.
This is a weird shape.
Concentrate.
This is it.
Where is it?
It's too close
Where is it?
It's here
It's not what I expected
Why?
The way they look is completely different depending on the angle and height
If you look at it while looking for various places
There should be an angle that fits perfectly like this
Let's do it again
If you do it again from around here, it's okay
If you look from here, it looks like that
Concentrate
It looks strange now, but it's okay
Jyo!
Jyo is hard, isn't it?
Why can't you see the Jyo?
What kind of touch was that?
Deceiving by touching
Sensei, what does this mean?
This time, the three-dimensional object looks like an ordinary object.
If you add movement to it, it looks like something impossible is happening.
I see. It's prepared for us, so please take a look at this.
I think it looks like there are two windows.
There's nothing strange about it.
It's on this window.
I'd like to go through a straight bar. How do you think it will go through?
Go through between the bars.
Between the bars.
Go through from there and go through from here.
And go through this back side.
Go through the back side.
Let's try it.
You look happy.
I'm happy.
I think it will go through like this.
Actually...
What?
It's amazing.
Why?
What's going on?
Go through once.
There are two.
This is one. It's straight.
Let's try again.
Up to here...
What's going on?
That bar is very soft.
It's hard.
If you want to see what's actually going on, go ahead.
Can you pass me the stick?
Don't act like you're just interested in yourself, Yamauchi.
You're an MC after all.
What's going on?
I want to see it.
What's going on?
Does it look like me?
What's going on?
How did you feel when you first saw it?
When I saw it from here, I thought it was normal.
Really?
Akiyama-san, you can go now.
Really?
What's going on?
Can I put it in too?
I saw it from here, it's normal.
I'll put it in.
Why? Are you just doing what you take for granted? What do you want? Liri too, Lili too. Eh, I have no idea. I don't know if I go there. How about Lily?
Eh, what's that? Eh, what's that? Eh, what's that?
It's normal!
Why?
It's normal when you look at it from the other side!
Normally, it should go through the back, but why does it go through the front?
Sensei, please tell us!
Let's try rotating it here
Actually, it looks like this
it's difficult...
You pull the string through the gap
I see
If you put this back...
Wow!
Amazing!
Just by looking at it from a certain angle, it looks like the figure on the right
The point is to make the fold in the middle look vertical
By doing so, the brain will recognize that it is protruding
So it's not like this, it's like this, right?
That's right. When you look at it from this side.
Why is it like that?
This line and this line are lined up in a straight line.
If you look at it with one eye, you will get an illusion.
You found it together.
Amazing.
There is another one behind.
I see.
Next is this three-dimensional.
It is said that if you add a certain movement, strange things will happen.
What will happen if you place the ball at the lowest point?
What will happen if you place the ball at the point where the ball goes like this?
If you think about it normally...
It will stop.
It will stop there, right?
Let's see what will happen.
I'll put it here.
It's so creepy.
Creepy.
Is there a motor?
I don't know anymore.
I want to go there.
It doesn't matter. Akiyama-san, please go.
I did it!!!!
I did it!
Did it come in?
Ouch!
Eh?
Eh? Why?
But is it normal?
It's normal.
If you want to see it, come here.
Eh? Why?
Azusa, come here.
You should definitely come here.
I want to see it.
It's normal.
First, please look at it.
Eh? What is this?
Eh? Why?
Come here. Put the ball down.
Ah, ah, ah, I see.
Eh? What is this?
Only people who came here can experience it.
Ah, only people who came here can experience it.
Eh?
What should we do?
Saebi, Saebi, come here.
Come here.
Is it normal to see it?
Yes, it is.
I'm glad I was chosen.
What?
What does it mean?
What does it mean? Why?
I got it, I got it.
I don't even know why you stopped.
I'm sorry, I'm sorry.
No, it's okay.
Why is it okay?
Come on.
The center is hollow, but why is the ball going up?
Let's see the actual thing.
It looks like this.
It's strange.
There's a slight slope, and the ball is rolling.
It was a V-shape a while ago.
The way the pillars are standing is also messed up.
The pillars are facing different directions one by one.
But if you look at it from the previous direction, it looks parallel, so you misunderstand that the pillar is standing vertically.
The pillars are standing at different lengths and angles.
If you look at it from an angle where the pillars look parallel, you would think that the brain is standing vertically.
You would have the illusion that a long pillar is equal to a tall pillar.
Actually, long pillars are lying down a lot, so it doesn't matter how tall they are.
I love this right angle, so I think the reason is that the pillars are standing vertically.
Mr.Namashido's illusion of reflection.
Sensei, what does this mean?
If you look at the mirror you saw at first, you can see a different figure.
I would like to show you another example.
I see.
If you look at the mirror you saw at first, you can see a completely different shape.
I was surprised enough, but what kind of thing will come out?
First of all, this one.
As you saw at the beginning, I think there are four diamond shapes lined up.
That's right.
If you remove the attached hand behind and move it to the mirror, this will be a different shape.
What is it? Please take it a little bit more, sensei.
If you remove the attached hand behind and move it to the mirror, this will be a different shape.
What is it? Please take it a little bit more, sensei.
It's like this.
What? What? What?
No, no, no
It's impossible.
You're too excited.
Too excited.
There is no way.
You've been pretending to be.
Wait a minute.
This is not.
Wait a minute.
This is not.
For example, this is just as it is.
That's the way it is.
That's why I don't think it's possible.
Even though the bottom hasn't changed.
Until now, everything has changed, right?
That's right.
The bottom hasn't changed, so I think this is a lie.
I'll only look at Akeba-san.
What? Really?
That's fast!
Really?
EEEEEEEEEEEH!? Sensei, I'm sorry!
Really? I'm sorry for lying!
Amazing!
Akarin, Akarin, look at this.
I did it, I did it!
I don't get it at all.
EEEEEEEEEEH!?
Why?
It's like...
It's not 4 of diamonds?
It's completely different.
No way!
It's weird.
Yamauchi, look at this.
It's completely different.
EEEEEEEEEEH!?
You're lying
You can see the reaction of Mr.Yamauchi
It's unbelievable
What kind of mechanism is this?
First, let's try to rotate it
Please try to rotate it
Like this
It's coming out
Wow
Amazing
This is amazing
I don't know what it means
Amazing
There is a formula
If you look at it from this direction, it looks like a diamond
If you look at it from here, it looks like a heart
If you calculate it, it becomes like this
You can do that
Teacher, you didn't cut this tool, did you?
It's guided by the formula, right?
Yes, the result calculated by the computer
If you send it to a 3D printer, you can do this
Do you use 3 or 5?
Yes, I use it
What does that mean?
The number of decimal places
6 and 8 too?
Probably
4 and 2?
I'm using it, of course
Where is the number?
Do we know the number?
The number is the number
You can do that, right?
For example, the screen on a normal TV is an electrical signal, and there are numbers on it.
The voltage is going up and down over time, so you can express anything with numbers, but in this case, especially,
when viewed from two directions, the numbers are together.
If you combine them, you get one shape.
I don't understand that.
But if you don't use numbers, it's more difficult to make.
It's not something you can make just by feeling.
I think numbers have great power.
Numbers have great power.
There's still more. Let's take a look at this.
This time, I don't need a mirror, but you can see the arrow, right?
Yes, you can see the arrow.
I'll try to rotate this.
I'm looking to the right now.
I'm looking to the right.
I'm looking to the left.
Eight.
I hate this arrow on the left.
This is cute.
I hate the left side.
He only looks at the right side.
If you look at the mirror, the three-dimensional effect changes.
But if you look at the mirror, the direction is reversed.
You're showing something completely different.
That's right.
Which way should I go?
If you rotate it 180 degrees, it will look the same.
The actual shape is the middle of the arrow pointing to the right and the arrow pointing to the left.
It faces right in front and faces left in the mirror, but in reality it's just in the middle, as you can see.
N
blogs
or
Yes
Well, if part of the liquid If you move to the mirror, it will disappear.
How about
Let's take a look.
There are six different types.
There is also a hand attached to the back, and there is a mirror behind it, but let's reflect on the mirror.
When I look in the mirror normally
the bottom half. The one below is gone.
Why Why?
Japan.
all right. all right?
Yes.
yeah, do you know?
Okay then?
the one below.
I drew it in the picture, and the top one is just riding on it.
But if that's the case, won't it be reflected in the mirror?
Oh, I see.
that?
I don't understand that, teacher.
Mirror below.
But in the mirror you can't see the mirror below.
I have solved the formula.
e!?
I have solved the formula.
why?
I have solved the formula.
Are you serious?
Did you solve the formula?
Explain.
Um, this, there is this.
Put it on the bottom like this, and what you see in the mirror is this one.
That's excellent.
eh!?
do you guess?
yes.
I solved the formula!
eh!?
The picture is made so that it can be hidden when viewed from this side.
The angle of the mirror can be seen well if you shift it a little.
In this way, the lower surface is attached to the ground, but when the lower part is reflected in the mirror by placing a three-dimensional object at an angle that looks like a hexagon, the lower part is hidden Then there is another one, so let's take a look here
This time, there is someone at the bottom of the ring-like object
It's an old lady, isn't it?
No, it's me. It's me. It's me in the photo
Let's take a look at this in the mirror as well
She found the 3D object
Can you explain what's going on?
The talks changed entirely
Wonder why you got that feature.
It melted in an instant!
Yes, it melted.
Really? Explain it to us.
This one is...
Pasted Yamauchi? Pasted only Yamauchi-san.
I don't understand what you're saying. That's a three- dimensional thing, isn't it? I mean God. It's a picture. A simple picture on the desk.
Does that mean that only Mr. Yamauchi is alive? What does it mean to be alive?
It's a picture like this Even if it were a picture like this
If you look at it from an angle, if you look carefully, you can see a mountain falling down.
Reflecting in a mirror means looking like this
The human brain loves to see things in a right angle.
So we try to see a picture in a rectangular shape as much as possible.
In order to do that, we don't look at the picture from an angle.
We look at the three-dimensionality.
That's how the brain recognizes it.
This is called anamorphosis.
It's an application of illusion.
It looks distorted.
It looks meaningful only when viewed from a special angle.
Is there something you do on a daily basis?
I think there are many kinds of art, symbols, and signs that I use on a daily basis.
This one, right?
This one has the color of a guardrail.
It looks like it has a little bit of color.
Let's change the angle.
This one.
I've seen this before.
You've seen this in the city, right?
The next one is the same.
Wow, it's a strange feeling.
Something is written here, isn't it?
Yes.
It looks like that only when viewed from a certain special direction.
How does it look normally?
Amazing!
What is this?
What happened? What happened?
It looks like this from a certain angle.
Really?
I really want to make this into a room.
How was it, everyone?
It was amazing.
I think it can be used for makeup.
You think it can be used for makeup?
I think it can be used to make my nose look higher.
There's no such angle.
It's the same angle.
I'm going to do it like this.
What are you going to make me do?
This time, the mission is to go around Kyoto and find a beautiful woman.
This time, Keiichi and Fu-chan also participated from NMB48.
This year was also a very successful movie festival.
Kyoto is on the stage.
In Kyoto, which has such a history and charm, you can experience various things and aim for a beautiful woman.
And the member who has the least sense of experience will get a penalty.
First of all, the three of you should aim for a beautiful woman.
Please choose your favorite kimono from the rental kimono Wakana-san, which also has a cafe on the first floor.
I changed my clothes.
It looks like Akari.
Fuu-chan, you look like a good girl.
What do you mean I look like a girl?
I usually wear white or blue.
But that's because my skin color is too bad.
Today I look like a girl.
You look like an adult.
She chose me because I look like a good girl.
Akari-san, you always look like a tough girl.
But today you look like a good girl.
Yes, that's right.
Today I look like a good girl for Instagram.
That's right.
You always look good on Instagram.
And the three people who changed into kimonos first went to the Danish specialty store Grand Marble.
This time, we will have you eat the freshly made Danish brown, which is limited to this factory, which is adjacent to the factory.
We will give you a quiz about Kyoto.
Only two people who answered the quiz about Kyoto can eat it.
In Kyoto dialect, Obu
What do you mean by that?
That's dangerous
Yes
It's not a school, it's a school
Yes, music club
Music club
You eat it everyday
What?
I got it!
Water!
Tea!
That's right!
That's cheating
First, Akarin gets a new Danish
The second question is...
What would you say to a guest who came to your house today?
That's difficult
I would give this to him as a souvenir
There is a separate oven
What is it?
Do you want to eat Ochazuke?
Correct
You are very good at turning
Akarin and Fu-chan got a new tennis shoe
It's hot
It's steaming
It's my first time eating bread
I'm happy
It looks delicious
It's chewy
It's very chewy
It's crispy
It's my first time eating such a crispy tennis shoe
And Senryu will tell us how she feels about eating a freshly made tenis shoe
If every morning is tenis shoe, it's the best
Isn't it good?
Tenis shoe, I'm satisfied just by the smell
Tenis shoe is the best
Agu and Ochazuke are a set
It's Obu
Is it Obu?
Agu and Obu are all different
It wasn't Agu
The one who made the most sense of the three is
It's Kyo
Really?
I enjoyed it just by the smell
Agu and Ochazuke are the best
Among the three, the one who didn't have the most sense is...
Next, they will experience shooting
Here, they will have to compete to see how many of the six targets lined up on the side can be defeated in 10 seconds
Now, let's start the real game
First, Akarin
Go!
Ah! So close!
It was standing.
I thought I beat that.
Next is Jo.
Go, go!
Ah, it's difficult.
The last one is Fu-chan.
She looks very funny.
She's good.
She got 5 cards.
Amazing.
This one.
Jo, who has the least number of cards to beat,
will be punished as a punishment game.
And then, she will go to Senryu.
Ta-da!
I failed at shooting. First close.
Ah, that's good.
Ta-da!
The point is to remember the angry face.
That's the point.
Could it be?
Yabuchi-san?
This is too cute.
Shoot it down, white plate and your Shin.
Disturbing wrinkles.
Shin?
The one who created Chisato, who has the most sense among the three...
Wind-chan.
Of the three, the one with the least sense was...
You shouldn't hit the mole so much.
Next week, we will challenge Kendo and spicy fried rice in the second half of the Kyoto tour.
Will she be able to become a beauty?
That was great, Fu-chan.
Your heart is overflowing.
But my heart is overflowing.
Your heart is overflowing.
I'm waiting for you to look at me.
Let's announce the winner of this week's punishment game.
The winner of this week's punishment game is...
Nagisa!
She solved the mathematical problem.
It's amazing that she solved the mathematical problem.
And the winner of this week's punishment game is...
Jo!
What?
Why?
