Hello everyone
My name is Mt. Hayama, a physicist who should be difficult.
Stop talking tough today that is physics
I think that I want to tell stories easy to understand for everyone
Do not you guys like this
From the unexpected idea far away from common sense in the world
It is various interesting so-called breakthrough
I think that innovation is sometimes created
Or from the opposite idea, the reverse approach creates various breakthroughs –
I think there are times when innovation is born
For example this is mass production of cars
100 years ago –
A lot of people moved to this car one by one
I’ve been doing assembly of automobile parts
But that is very inefficient
Then the next opposite idea is born
It moves the car in reverse
This is the start of a belt conveyor
By doing so, this time the car moves without moving people
People stick to it and make parts –
That’s why mass production of cars was born
In this way the opposite idea plays a very big role in the real world
Actually, this opposite idea is the same in our world of science
We create various breakthroughs
While introducing this story to my actual research
I think I want to talk to you
This year’s Nobel Prize in Physics
It is to verify the gravitational wave from the collision of the black hole
Actually Einstein had predicted 100 years ago
Now that 100 years have passed since I saw this verification in this world
It is very pleasing as a scientist
After this, in fact it is a matter of neutron star
The gravity wave coming out there was verified
Actually, this neutron star itself has a big mystery
We scientists are now very interested in this neutron star
So, I would like to talk about what neutron stars are
The universe here is
Born by the Big Bang 13.8 billion years ago
One billion years later stars are born
The life of the star is that when I was born I made the sun ‘s fruit 8 times as a boundary –
The fate changes on the limit
That small star of the universe –
A star smaller than what is called the sun 8 times
Then it turns into a white dwarf and quietly burns up
A star bigger than 8 times the mass of the sun then has a supernova explosion
The interior of the star becomes black hole or neutron star
We are very interested in this neutron star in this
If you say how big this neutron star is
It’s about 20 kilometers in diameter
That is the center of Konan campus here
It is about the size to reach the station of Sannomiya
Although it is such a small star
Actually, this maximum mass is very large
Actually it is 1.5 times as much as the sun
Actually this is written in the universe textbook properly
We also regard scientists as common sense
However, terrible things happened in 2010
What a pain replacing textbook happened
It was actually realized that twice the mass of the sun was the greatest mass
This scientist greeted me with the greatest surprise
From everyone’s point of view it has doubled from 1.5
Although it may seem like I do not think it is anything
We theorist actually say 1.5 times the sun which is thought to be this common sense
Actually, I tried to explain in theory and made various efforts
But using a bad idea
It is easily 1.1 times the mass of the sun and 1.2 times
It hardly reaches up to 1.5 times –
Where we were accumulating that kind of effort
It has brought a value twice as far as 2010
We were pretty shocked
I still remember but I could not sleep at night
How can we solve twice the mass of this sun?
It is a very hot concern as a very important concern
So what is called a neutron star which is twice the mass of this sun
I say what you are made of and read like a letter
A lot of neutrons and a little proton and called hyperon –
It is said that it is made of particles that do not exist on the earth
To do this research
Actually, as input
The force between this proton and neutron
And the force between Hyperon and Yoko
Or the force between this red and white is important as input
However until now
Actually, I knew the power between this white and blue [about]
But the power between red and blue or red and white is
Actually I did not understand well until now
But in order to solve twice the maximum mass of neutron star
By all means this power is important
As a clue to a solution – one thing is possible
One thing is to artificially make this neutron star on the earth
But please think about everyone
You make stars that are twice as big as the mass of the sun on this small earth
Do not you think it is dangerous?
If you make a mistake a bit, it may become a black hole
Scientists should not do such a thing
Then, there is another idea in the opposite direction again here
Let’s look at the neutron star itself in detail finely and finely
Then the first smallest unit I watched in detail is
This proton, neutron and hyperron are made up of three particles
These three particles or these four particles
Consider making artificially
Call this atomic nucleus made of hyperon, proton and neutron “hyper nucleus”
This hypernuclear is made artificially in this accelerator facility
Hyper nucleus made at this accelerator facility –
It is theoretically to solve this structure
Among them, Hyperon, proton and neutron are made of these three particles
We call this a “three body problem”
Also, what is made of four particles is said to be “four body problem”
It will do theory to unravel this three body, four body problem by theory
You can count them like three bodies, four bodies
However, it is extremely difficult to theoretically solve three- or four-body problems
Let’s take a look at the next human society and talk about why it is difficult
For example, if you think about getting to decide something with friends who are good friends
I think that it is relatively easy to decide things because it is knowledgeable
But there is one popular difficult person – a person who does not like it for a while
For example I think that it will come
This is a three body problem
That means that things that were easier to decide earlier become complicated more quickly
I think that everyone has experience
Suppose another person who is hard to please comes in here
This is a 4 body problem
It gets even harder
Earlier it was easy to decide if it was a two-body problem
The problem of becoming a four-body problem is to get ridiculous
I think that experience may exist
Actually this is the same in the micro world
It becomes complicated and strange when it comes to a very many-body problem
There may be people who start to sleep as soon as they are represented by mathematical expressions
I will reveal such a formula
Among them, this “V” is the word “power” I mentioned earlier in the input
Then, unraveling this formula and saying “E and ψ (ぷ っ)”
This is to unlock with the output
This can actually be compared with experiments
To unravel these expressions exactly and to give out E and ψ
Actually, it is one of the objectives of my research
When solving these problems
So far as this power is definitely given out
Solve the expression earlier and put out the output
And it has been possible to compare with experiments
Actually, however, if we could not do the fundamental power of this power
What should I do? I can not put out an output
It actually came into conflict with this kind of problem
So I thought about it in the opposite way
In other words what do you mean?
I will solve my problem formula exactly
So it is a power that I do not know well
Anyway use it to solve firmly
We will compare and examine it with the output as an output
In fact, you can actually give a correction to the force in the opposite direction
The power that we did, the reliable power this time to the study of neutron stars
It is because I thought of giving it as input
By doing this kind of project
The mystery that we said twice the mass of the sun of neutron star –
We feel that it is not long ago to unlock this
It was the last time to talk about today
This is an opposite idea in the opposite direction
By thinking about this opposite approach in science society
I am experiencing that clues to various solutions spread quickly
Actually this is not just the world of science
I think that it is also important in the real world
For example, if you try to do a new project launch
Be sure to hit any problems – hitting a wall
I think that I have experience.
By overcoming the wall or breaking through the fronts or by going straight ahead
I think it is common to solve by chance or something like that
But I think there is something that does not go well
Look at that kind of view from a different perspective –
Think in the opposite idea
Things that were difficult until then
I think that it is common to solve in a blink of an eye
Everyone is going to be a new issue from now on
I think that it seems to be challenging more and more
Please remember when you hit the wall
This is an opposite idea in the opposite direction
Thank you very much
(applause)
