Ministry of Education: Wait a minute description of textbook revision seismograph!
Recently, Zhang Heng's
abercrombie and fitch outlet seismograph after restoration controversial everywhere, and primary and secondary school textbooks used in recovery after the seismograph is appropriate? 3 November, the Ministry of Education in reply to "Legal Evening News" reporter, said that the disputed seismograph in the world, school textbooks should be described is a professional issue, relevant departments of the Ministry of Education has the relevant information to the national basic education curriculum teaching profession Committee for further study. Our Ministry of Education, the Ministry of Education
burberry handbags is indeed the people, work efficiency is fast. September 4, 2009, Premier Wen Jiabao in Beijing to listen to 35 middle school after-school geography that "Shaanxi, Gansu and Ningxia, North China classified defect." This is not the Ministry of Education flew in this year's new materials, the North China no longer separate into sections, but extended into the northern region, which has caused controversy in the Ningxia region also was included in a map
burberry outletof the northern region. Moreover, a large high school textbooks this year, "Changing Faces" - Lu Xun to a great retreat! So why the hurry of the Ministry of Education to modify school textbooks describe seismograph? According to science writer Fang issued a document on Zhang Heng seismograph questioned whether the works. Fang said that China made in 2005 restored seismograph model, in 2008, when the quake, felt in Beijing, have not heard of the recovery model to monitor the earthquake. December 2, Li Henan Museum researcher interviewed said that in 2005 restored version of the Zhang Heng seismograph model itself is unable to monitor the actual earthquake. Oh, so it is no wonder that people rush to the Ministry of Education of the major textbook revision. Well known, the Eastern Han Dynasty in China Zhang Heng great astronomer, mathematician, inventor, geographer, mapping scientist, poet, Han officials, to our astronomy, mechanical technology, the development of seismology has made an indelible contribution. Because of his outstanding contributions to astronomy organizations, the United Nations in 1802 was the solar system asteroid named "Zhang Heng Star." People more aware, Zhang Heng seismograph is handed down the masterpiece, in the Eastern Han Dynasty, Zhang Heng in which the era of more frequent earthquakes

According to the "five elements of the Later Han" records, since the Dili Yongyuan four years (AD 92) to Andi Yan light four years (AD 125) of thirty years, there were twenty-sixth major earthquake, Sometimes the earthquake zone to dozens of counties, causing the crack landslides, river flooding, house collapses, causing huge losses, Zhang Heng, many first-hand experience of the earthquake, in order to grasp the seismic dynamics, after years of research he finally Yang Jia Dynasty (AD 132) invented the seismograph which is one the world's first seismograph. According to the "Biography of the Later Han Zhang Heng" records, seismograph of "refined cast, round diameter of eight feet," "shape Jiuzun", a raised, round cover,

Instrument has an internal central copper "are columns", retrofitting has eight channels, known as the "eight, there are clever machine off. Bottles around the eight leading outside the body, according to the east, south, west, north, southeast, northeast, southwest, northwest direction of cloth out of eight. faucet and the internal organs of the channel's launch is connected, each leading his mouth is a copper ball title. against the leader, eight toad squatting
marc jacobs handbags on the ground, all Angtou mouth, ready to undertake the copper ball. when there was an earthquake, along with bottles of body movement, touch the organs, leading to the direction of the earthquake opened his mouth, spit copper ball, copper fell toad's mouth, a great place sound. so people can know the direction of the earthquake. Shundi Yang Jia Han Renyin November for three years (AD 134 on Dec. 13), a seismograph suddenly launched dragon machine, spit out the copper ball, fell into the toad's mouth. was in the capital (Luoyang) people
marc jacobs bags felt the earthquake but did not sign, so people started talking about the blame does not come true seismograph. a few days, Longxi (now Gansu Province, Tianshui) was Pegasus to report, confirmed that there did occur a few days before the earthquake, so people began to Zhang Heng's superior technology is very convincing. Longxi more than a thousand years away from Luoyang, seismograph labeled correctly, that its seismic sensitivity is relatively high

Now, only a few behind closed doors because the fiddle out of the brick home less than a seismic monitoring of the recovery model to a denial of the great scientist Zhang Heng's masterpiece - seismograph, who can guarantee that the brick house crunching the impulsive recovery model and the Zhang Heng's candidate exactly the same seismograph? Ministry of Education, plus getting laughs are, you are too subjective, emotional, mistakes are too low grade! well known, the Three Kingdoms era of Zhuge Liang invented the wooden ox, with its rugged path along the cliff in the delivery of rations, and "People do not labor, cattle are not eating". "Three Kingdoms",
ugg"Three Kingdoms" and other books on Zhuge Liang's wooden ox have carried out a vivid, vivid, very detailed description. So, smart people today still copy the clone can not "wooden ox "The Ministry of Education to deny you," wooden ox "exist? Finally, Cao Min, Ministry of Education would like to say is, do not mind always used in those far-fetched and thankless things! or the mind is used in urgent need to address the issue of it: the children of farmers schooling and an education issue; Qian of asking questions; backwardness of rural education; Education imbalances; education corruption, etc., etc. This is important in the Ministry of Education should pay attention to The re-ah
