Travel to Science Light: Einstein from Al Hajen

Egypt is the donation of the blue river. That blue river flows Egypt every year to flood. That trend is going on for ages. The tenth century Egyptian caliph sought eternal freedom from the flood. That is why he went to Iraqi Pandit Al Hasan bin Al-Hayasam Latin and European scientists, who know Al Jazeen Hassan came to Cairo. A project to build a dam was taken into account by monitoring the flood situation. Hassan verified that the construction of the dam could not be possible. But he did not say the caliph Rather than looking for the day, day after day. There are many advantages of being a royal scholar. It can be researched as well, there is no tension in money and pottery.

The construction of the dam is not possible, so that Al-Hajen started using the money and the advantage of the king scientific research. Some of the fundamental works done on the light. The famous Greek philosopher and mathematician Euclid believed that light came out of the human eye. The light went on to go about the object. Then people can see that object. Euclid's idea is wrong, school children understand it too. But in the tenth century it was not easy to understand. Goddess of the Greeks in world science. In the second century Ptolemy has misunderstood most of Aristotle's ideas. There is no exception to light. Euclid's misconceptions were misinterpreted by the era of the era of age. Al Hajin has stole the idea. He said, not from the eyes of the person, when the light comes from the object and reflected on our eyes, we see the body. Many of them came back to the ray again, crying screaming because they were born. How does the al-Hajjena's assumption of how to throw the theory of Wicked-Ptolemy! Then Hazen was supported by two famous scholars of Arabia, Ibn Sina and Al-Biruni.

Al-Hazen could not build the dam. So the caliph had a time of rage. It is heard, then there was a hood of madness in Egypt, in Egypt. Do research in secret light. Writes - Kitab Al-Manajir, a book in light of seven volumes. In the English translation whose name is Book of Optics. Hajin said in this book, the light goes down from the medium to the light, it slows down. Before that people thought light speed was infinite.

After inspiring the idea of Hazin, the famous French scholar Roger Beacon of the thirteenth century He agreed with Al Hajen and said that the speed of light is much more. More than words, but the speed is not infinite. Then another theory was about the speed of light. Scholars thought that the speed of light through zero was infinite, but the light became dark after going through the air medium.

Al Hajen's theories of the famous German scientist Johann Kepler also came in the seventeenth century. He also wrote a famous book on the light of the optics. The book that fills Newton's photographic research. One of the foundations In that book Kepler writes, there is no impediment for the light movement through zero.

1629 years Dutch philosopher Isaac Bakerman offered a test. A light bulb from the cannon, it must be reflected in a mirror a mile away. If it takes time to reflect on the return, then there will be light speed limit. But nobody has seen that test.

Nearly Italian physicist Galileo Galileo made such a test. However, Galileo did not know about Bikan's offer Galileo saw that light does not take time to cross the distance. That was Galileo's mistake. Lighting speed is very high. In the second one thousand six thousand thousand miles So it will take light time to reflect a mirror that is one mile away, only one part of one thousand six thousand of one second. Galileo did not have the technology to scale so much time. So he did not realize that the light took time to move.

French astronomer Giovanni Casini At one point in the middle of the seventeenth century, a surprise was noticed. We know that the planets of the solar system are rotating around the sun. Everyone has a specific orbit. The orbits are not round. The ellipsis So its planets are not always the same distance from each other. The same happens in the case of Earth and Jupiter. Cassini was observing the planets of Jupiter's planet. Jupiter satellites are already predicted to be predicted. And that's very easy. Casini saw that Jupiter was very close to the world at the time of the year, before it was assumed to be taken several minutes before. Again, when Jupiter is the most distant from the sun, it can be seen at some time after a couple of minutes. What does this mean? Its explanation was not to the cassini. Then came the Dennis astronomer Ole Christensen Romar.

When we get light from an object or source, we see the object when our eye strikes the retina. The difference between Jupiter's two acceptance periods is that it takes two different times to get light from two places. Romana thought it meant only one. Lighting is not an immediate event. That is, there is a certain speed of light. But the speed of light is very much.

Jupiter is the distance of the earth. The distinction between distances in two different times of the year is also less. So the events of accepting Jupiter's satellite proves the speed of light. The speed of the light of Romar is one hundred and forty thousand miles. It is far less than modern measurements. But at that time the speed of light was not such a fine device. So this value of Romer's measurement is of great importance.

In the seventeenth century, Christian Hygens said, the sound like the sound continued in wave. Earlier, Newton said that the light is actually the smallest particle particle in motion. The media needs to be in the wavelength. Let's talk about the words. The sound makes waves in the air chest. Then the wind shook and spread it around. What does the wave of light waves on? There is no question of wave blowing in the air. What is the mode of movement?

Then scientists imagined an invisible medium. His name is Ether. It is assumed that Ether has existed at zero places. But the problem remains. If there is light in Ether, there is everywhere in it. Does the light rays come from the stars of the distance from the star of Ether? Or the whole universe submerged in iter?

In 1865, Scottish physicist James Clark Maxwell established his famous electromagnetic equations. This equation is called light electromagnetic wave. Maxwell came out of the equation, there is no need for light waves to run. The dynamic magnetic field produces electricity or electrical conditions and dynamic electromagnetic magnetic conditions. Originally the idea of Maxwell's electromagnet theory was born. And this theory created doubts about Ether's ideas. Because it has come out from the specific values of the speed of light. And in that second one hundred and forty six thousand thousand miles or three lakh kilometers.

The trouble is with Ether. Maxwell could not believe Ether's case. The sound runs in the air. As long as the sound wave can hold the least energy. We see the sound wave can not continue continuously. Once it was forced to stop due to obstruction of air. If Ether is the medium of light, then he is able to stop the light! But the light can never be stopped. Maxwell told the Secretary of the Journal of the Royal Society 'Proceedings of the Royal Society. But editor Maxwell did not seem to be reasonable. American physicist Albert Mickelson was inspired by Maxwell's idea.

In 1887 he conducted a test with another American scientist Edward Morley. Michaelson-Morley runs the light speed test twice in relation to the Earth. Once the speed of light is determined to move towards the motion of the Earth. From a light source, Michaelson and Morley sent two light rays in two mirrors. They found the exact speed of light speed twice the same. This test proves that the speed at which the speed of the train is different in the station, such as the other dynamic bus or the train is different, the event does not happen in the light.

If there were an Ithar wave, there would have been twice as many results. But Michaelson-Morley got the same result. What if there was no barrier to Ether? Michelson-Morley's test really proves that there is nothing Ither. The test is, the proof is that the proof is. But the explanation is not. But Ether's existence broke. It's been a long time to wait for

That means that the existence of Ether broke. But many scientists could not believe it. They started raising various projects to overcome Ithra's complexity. In particular, some scientists were totally unhappy to exclude Ether. So they adopted different ways to hold Ether. Among them, the Irish scientist Fit Gerald's was one of the projects. He said it took more time to return the light sent in motion, but due to the speed the length of the interformometer was shrunk. That is, the direction of light decreased. This pathway has decreased as much as possible, while the light sent by north-south can return to the time it returns. The extent of the contraction depends on the speed of the object. Here the interfomometer is running at the speed of the earth. He calculated that if an object of 1 meter is half-speed in the light of light, its low will stand at 0.866 meters.

Due to his project, Dutch scientist Hendrik Anton Laurent took another project. Fitzgerald and Lorentz set up the Fitzgerald-Lorentz project. They use several equations in this project. Maxwell's electromagnetic equations can be used in two different intersections through the Fitzgerald-Lorenz project. These sources are used by Einstein for his theory. But FitzGerald and Lorenz used to use the equations to prove that Ether was saved and not the velocity of light. Istine proved the velocity of the velocity by using those. Einstein relocated Galileo's transformational equations to the theory of theoretical convergence in the Lorentz conversion.

These problems emerge from Micheles-Morley's tests. But they could not solve it. The solution came in 1905. With Albert Einstein's hand. The velocity of the velocity of light came out. Einstein further said, more speed than the speed of light can not be any object. Einstein's theory still reigns in the heart of natural science.
