Editing Zhang Heng (section)

===Posthumous honors===
Zhang was given great honors in life and in death. The philosopher and poet [[Fu Xuan]] (217–278) of the [[Cao Wei|Wei]] and [[Jin dynasty (265–420)|Jin]] dynasties once lamented in an essay over the fact that Zhang Heng was never placed in the [[Nine Ministers|Ministry of Works]]. Writing highly of Zhang and the 3rd-century mechanical engineer Ma Jun, Fu Xuan wrote, "Neither of them was ever an official of the Ministry of Works, and their ingenuity did not benefit the world. When (authorities) employ personnel with no regard to special talent, and having heard of genius neglect even to test it—is this not hateful and disastrous?"<ref name="needham 1986 volume 4 42">Needham (1986), Volume 4, Part 2, 42.</ref>

In honor of Zhang's achievements in science and technology, his friend Cui Ziyu (Cui Yuan) wrote a memorial inscription on his burial stele, which has been preserved in the ''Guwen yuan''.<ref name="xiao knechtges 1996 398">Xiao & Knechtges (1996), 398.</ref> Cui stated, "[Zhang Heng's] mathematical computations exhausted (the riddles of) the heavens and the earth. His inventions were comparable even to those of the Author of Change. The excellence of his talent and the splendour of his art were one with those of the gods."<ref name="needham 1986 volume 3 359">Needham (1986), Volume 3, 359.</ref> The minor official Xiahou Zhan (243–291) of the Wei dynasty made an inscription for his own commemorative stele to be placed at Zhang Heng's tomb. It read: "Ever since gentlemen have composed literary texts, none has been as skillful as the Master [Zhang Heng] in choosing his words well&nbsp;... if only the dead could rise, oh I could then turn to him for a teacher!"<ref name="declercq 1998 247">Declercq (1998), 247.</ref>

Several things have been named after Zhang in modern times, including the lunar crater [[Chang Heng (crater)|Chang Heng]],<ref>''Lunar Names Proposed'', 290.</ref> the asteroid [[1802 Zhang Heng]],<ref name="schmadel 2003 144">Schmadel (2003), 144.</ref> and the mineral [[zhanghengite]]. In 2018, China launched a research satellite called China Seismo-Electromagnetic Satellite (CSES) which is also named Zhangheng-1 (ZH-1).<ref>{{Cite web|url=https://www.nasaspaceflight.com/2018/02/long-march-2d-zhangheng-1-earthquake-investigator/|title=Long March 2D launches Zhangheng-1 Earthquake investigator – NASASpaceFlight.com|website=www.nasaspaceflight.com|date=2 February 2018|language=en-US|access-date=2018-02-05}}</ref>
