The shut-down system

As computer develops, people have enjoyed more convenient and comfortable life. Besides, it leads more scientific achievements. Even it leads human to explore space. It's undeniable that the Apollo project, which was the first step of human space-exploration, was feasible by development of computer technology. 

Video game and Computer game has developed simultaneously with the development of computer. Now "Game" is really realistic. In some games, we can even see characters are sweating, and it is advancing. 

The scale of game industry of world is surmised as 122 trillions won. 

In korea, the scale of domestic game industry is 10 trillions won. Moreover it has created 100-thousands jobs. And it is predicted as it will continuously grow up 

However, something starts to disrupt it.

The shut-down policy was enacted mainly by the ministry of gender equality and family in May,2011. The ministry stated "Game is drug." Every Adolescents are compulsorily kicked off in any conditions at 12 a.m. 

Because of this system something awkward happened before. 

He is adolescent pro-gamer. When he was playing a game in the league, he abruptly gave up. He said " I gotta go, because of shutdown system." Although he is  an officially enrolled pro-gamer, he had to give up. 

The shutdown system also has advantages either. Because of the system Adolescent can not excessively play game. And it leads them to have regular-life. In other words, adolescents can have time to do what they have to do which is study. 

What do you think about it?

World of space time

What if we chase the light with same speed with it? 

Einstein was wondering about it everyday and every night. 

If we sit in a subway lookout of the window, and watch the car which has equivalent speed with it, it looks stagnant. We all know this. 

Can we adapt the situation above into light? 

The velocity of light is almost 300,000 km/s. 

Is it going to be stagnant, if we chase with equivalent velocity? 

No, It isn't

It is still stretching with formidable velocity. 

Einstein contrived the theory of relativity from this question.
And finally concluded as "Time goes differently, and it depends on quantity of motion of object."


Then, what is speed?
Speed is, generally, dividing moved distance by time.
In other words, it is dividing of space quantity by time quantity.



What is movement?
Most of people may answer, " It's just a move of object."
It's wrong 
Movement = Movement in space + Movement in time

Every stagnant thing is taking movement in time
and every moving thing is taking movement in time and space simultaneously.



A stopped car is taking movement only in time. However, when it starts to move, it consumes a part of motion which it uses in movement in time to movement in space.
The quantity of motion is absolute. It can't be doubled or increased.
It might sounds weird, but time of the person who drive a car in front of you is passing later than your time.



Hafele–Keating experiment

Hafele and Keating did a experiment to examine the theory of relativity in 1971. They equipped  8  cesium atomic clocks. 4 of those were on the ground, and the other 4 were in the airplane. After the flight, clocks which were in the airplane were 59/1 billion seconds later than the clocks on the ground. 

Einstein was right.

There is no exact 12 a.m.

Gravity

It is better to view this page with the music above.

Recently, the movie "Interstellar" is sweeping all the people's attention in Korea. Some might say "It's fantastic, it's really interesting." The movie's genre is SF (Scientific-Fiction). There are many scientific materials in it. The most fundamental two theories of this movie are Gravity and Space - time. I'll inform you briefly about gravity in this page. 

Issac Newton contrived the theory of universal gravitation. It's well-known story that Newton invented the theory because of falling apple. It sufficiently explains why people in the south hemisphere do not fall off to the space. Simply, Gravity is the tension between two objects. 

However, someone broke the theory, and it was Albert Einstein. 

He invented "Special theory of relativity" and "General theory of relativity" in 1905 and 1915 respectively. Time and space were absolute and immutable subjects at that time. So, he was blamed much. But now, it becomes the base of science. 

In Newton's theory, gravity is the interaction of two objects. However, in Einstein's theory, gravity is rather a space-time distortion than a just power. 

Einstein saw the space in 4D. 1D is line or dot. 2D is face. 3D is solid and volume. 4D contains Time and everything in 1D,2D,3D. In Newton's theory, the revolution of moon is explained by "Gravity." But in Einstein's theory, it is explained as "Parallel condition in space-time distortion. In Einstein's theory, every-planet in the space creates invisible space which commensurate with its mass under itself. You may don't comprehend the picture above. Imagine there are bowling ball and golf ball. If we place those on a mattress, bowling ball will dent deeper than golf ball. Moreover, if the golf ball is near by the bowling ball and stagnant, it will fall into the dent. So it needs to revolve the dent with moderate speed to prevent collision. 

What is more? 

If light goes in a straight line we can not see stars which is behind the sun. 

However, light tends to take the shortest distance ( according to Fermat's principal). 

So the light of the star behind the sun is not taking the way to go through distortion distance. It takes a detour. 

 Actual location and observed location of star are different, because light doesn't go straight. (Gray line is the actual way of the light of the star takes)

 The then Time's Headline 

"Revolution of science - New theory to explain space - farewell to the Newton theory."  

"We still don't know one-thousandth of one percent of what nature has revealed to us."

Albert Einstein 

(1879-1955)
