Xi Meng origin, birth and death unknown. Han people, active in the 1st century AD, before and after. Astronomy.
On the life of Meng Xi, left no historical records of the material system, currently only the records from a number of pieces
He has extrapolated the Eastern Han Dynasty in the doctor, after promotion to Zhonglang. Han Langguan is no specific duty free
Officer, usually on duty guards at the palace where the emperor from touring to accompany, to serve Juji, usually readily available to the emperor to build
Yee, waiting for the emperor's special dispatch. Langguan was _select_ed because of the frequent collection of books to the secret record of the Royal East view
Work to complete the typical school secretary or the task of writing essays repair, these Langguan also called Mishu Lang. "Book of Jin
* Astronomical records, "and" Sui Dynasty astronomical records, "Meng Xi said that the" Han Mishu Lang. " Also, according to "World Ruixiang
Chi 'records, Xi Meng also worked Taishi order.
According to Ban Gu's Han Dynasty, "Code cited order" records, Yongping seventeen years (1974 AD), he and Xi Meng, who has
Should the Han Emperor Ming of vocations, to discuss the evaluation of historical figures. Many people mentioned in the text view of the then East
Code Langguan school secretary, Meng Xi can be seen active in the 1st century AD, before and after.
Meng Xi's major contribution in astronomy, is the tradition, the ancient Chinese theory of the universe, one of three infinite space.
According to the "Book of Jin astronomy," it reads: "Han Mishu Lang Xi Meng Kee and teacher legend goes: days no matter, the Yang and Zhan,
Lofty Promise, eyes dim absolutely fine, so the green and ran. Give an example of Huangshan Road, next to long-term perspective and are green and look down thousands of feet deep
Valley and Miu black, husband non-true-color blue, and black body is not there. Sun, moon and stars, the natural Bliss emptiness, its line of its
Only are required to air Yan. Is Qiyao or death or to live, or along or against, Fushimi impermanence, retreat varies from almost nothing to the root
System, it is different also. Chen ranking it very often so, but not with the Big Dipper stars West did not have. Photo mention Tianxing all eastbound
On-line once a month line of 13 degrees, Chi Ji Ren Qing, its nothing tied see carry on. If the suffix attached to objects, not Seoul
Also. "From the text we can see, this theory has two main advantages: First, with the ancient Chinese celestial dome
And the celestial globe that the days that the body is different from a hard solid, it denies the physical quality, the size of the day, put
A simple concept of the infinite universe. Second, muddy, covered two just shows a day, month, stars of the operation
Dynamic situation, not a theory of stellar movement seriously raised the issue of driving force, while the infinite space that day,
Month, the stars of natural Floating in the emptiness, the material of the "gas" is to control their movement, so that changes that occur during
The fundamental factors. These two points in the history of cosmology is a progressive significance.
Declare that long night, after another following the Xi Meng new development, but as a theory of the universe, it did not
To explore in depth the day, month, five-star running specific laws, nor make their own independent measure of celestial coordinates
And its method of movement. Therefore, from the practical or the development of mathematical astronomy point of view, its influence far and celestial globe
That large. However, in the history of the universe of human knowledge, infinite space no doubt occupies a important position. As
The infinite space of the ancient theory of the other long lost, so as far as we know the only descendant of the doctrine of Xi
Meng will become infinite space of the main representatives.
Xi Meng or bit astrologer, in the "Sui Shu Jing Ji Zhi" and "astronomy to record" Meng Xi recorded in the
