What is the history of cosmology timeline?

The research on this mineral world was started a long time ago and the total time period from that beginning moment is considered as “cosmology timeline”.

 The word cosmology is the combination of two Greek words, “Kosmos” and “Logos”. The meaning of the words are world and science respectively. From that point of view, the meaning of the word cosmology is the science of the world. So it is clear that cosmology is a special science that deals with the causes or phenomenon of this organic or mineral world. The scientists of cosmology formulate some of the theories to explain the condition of this mineral world like the availability of the light, heat or electricity. The research on this mineral world was started a long time ago and the total time period from that beginning moment is considered as “cosmology timeline”. In this article the beginning history of “cosmology timeline” will be highlighted to inform them the introduction of this special field of science.

Cosmology Timeline

The discussion of the history of “cosmology timeline” began with the research of Pythagoras and the time estimated between 500 BC to 300 BC. Pythagoras assumed that the earth was in motion and he tried to find out the numerical relation between the earth, planets, sun and moon. He assumed that all the planets, sun and moon are in motion with the earth in a harmony of music and he considered a big sphere as the music of the sphere. Then he taught Aristotle that the sun, moon, planets and the other stars are in motion around the stationary earth and those are carried away from that big sphere. Pythagoras also taught Aristotle that the earth was unique as stated at the central position and also for its composition of minerals. At that time both Pythagoras and Aristotle have tried to calculate the distance between the earth and the moon but they failed to do so.

In the later part of the history of “cosmology timeline”, after Pythagoras and Aristotle another scientist named Aristarchus also kept a special role in this history. He was a famous Greek mathematician and astronomer. He is the first man who proposed the idea about the modern model of the solar system. According to his idea, the position of the sun is at the center of the universe not the earth. And on the basis of that he predicted that, all the planets are in a correct order considering with the sun. After him, in the 200 AD a scientist named Ptolemy gave another idea which was similar to the Pythagoras’s idea. But in his theory, the earth was also in a motion with the neighboring Sun and Moon.

The history which are mentioned are the history of “cosmology timeline” at the beginning stages of research on the cosmology science. Basing on the previous theory, the modern cosmological theory is established. Without the efforts of those scientists, it becomes impossible for the scientists of this generation to reach in this level. It's the hard work and desire of those scientists which is helping the scientist of this generation to achieve the success in this field.

What are the remarkable achievements of Stephen Hawking?

Stephen Hawking is the name which is well known to the people of the whole world for his remarkable achievements throughout the lifetime.

Presidential Medal of Freedom” The mentioned awards are the remarkable achievement of Stephen Hawking."

He is one of the special names that will be kept written with golden letters in the scientific community. His astonishing observations and perfect explanation of those observations has helped the world of science to advance in a quicker way. Stephen Hawking was born in the United States in the year 1942. But he had to return London as both of his parents are from there. He had completed his graduation in the year 1962 from the Oxford University. After the completion of the graduation, he became famous within a short time for applied mathematics and theoretical physics. An accident happened at that time which made him a paralyzed patient, but that accident couldn’t stop him from his determination rather all his remarkable achievements are after that accident.

The first mentionable achievement was the Eddington medal in the year of 1975. Though Stephen Hawking was paralyzed and was unable to speak, he was the man who kept a massive contribution for the breakthroughs of the theoretical physics. And the Eddington award was given to him as an honor for his remarkable contribution. As the scientists found his contributions as something special, they nominated his name for the Albert Einstein Medal. And after that nomination, Stephen Hawking received the famous Albert Einstein Medal in the year of 1979. After that he was named as the fellow of the famous Royal Society and he is one of the few people who received this honor in the early stage of life.

The “Wolf Prize” in Physics is considered as the most prestigious award after the Noble Prize and Stephen Hawking won that price in the year of 1988. He won that famous prize for his hard work and deep research on the two most important topics. The two topics are Big Bang Theory and the Black Hole theory. He wrote a famous book named “A brief History of Time” where the proper explanation of the two mentioned theory was added and that book is the bestselling book from 1988. For his outstanding services in the field of science he was honored with the award Copley Medal arranged by the Royal Society in the year 2006. His last award is the “Presidential Medal of Freedom”  in the year 2009 and this is the highest honor that can be given to a citizen of the U.S.A.

The mentioned awards are the remarkable achievement of Stephen Hawking. But without those achievements, this famous man had won a number of awards over his life span. He has kept a remarkable influence in the field of science especially physics. His outstanding contribution will help the scientist of the next generation in many ways. At the very end it can be said that, he is the person whose name will be written in golden letters for the next thousand years.
