How Chinas science renaissance has already begun 有“超级天眼”之称的贵州FAST射电望远镜开启天文发现新时代； “千人计划”吸引海归科学家；以“博物君”为代表的科普浪潮 正在大众中兴起。在中国，科技备受瞩目。 “Im really not very interested in science， Im sorry to say，” claims the chief scientist and engineer of the worlds largest radio telescope， Nan Rendong. Joking or not， its probably fair to say that theres never been greater interest in science among many Chinese today. Although the government has always ostensibly promoted science， incorporating slogans such as “scientific development” into its rubric， policy and practice has not always lived up to ambition. Yet today， China may be on the cusp of a new scientific revolution， announcing fresh discoveries and plans with head-spinning regularity. And while， to be sure， not everything is likely to pan out perfectly， the sense of optimism is enough to ensure that more and more Chinese and foreign scientists are considering investing their time and research skills in mainland laboratories， rather than abroad. Over the next few pages， we examine a few of these advances， from the engineering triumph of the FAST telescope， to the scientific returnees and young people finding new interest in the natural world on Weibo， examining both the challenges and possibilities that lie ahead—in the next and possible final frontier. STARSTRUCK TEXT AND PHOTOGRAPHY BY WU HAO （吳皓） In Guiyang， the worlds largest radio telescope is taking astronomy—and the local economy—rapidly into the future I t takes at least five hours hard driving from Guiyang， plus a vehicle change if using public transport， to reach the place many now call “the future of astronomy.” Kedu has a population of around 30，000， and around 10 percent are on the poverty line； the rest are mostly rice and corn farmers， making an average 8，000 USD per capita. It is also home to the 185 million USD， Five-hundred-meter Aperture Spherical radio Telescope—known as FAST， and nicknamed “the Eye of Heaven.” Currently the worlds largest radio telescope， FAST nestles inside a vast natural karst depression in remotest southern Guizhou province， silently searching for signs of extraterrestrial activity. The huge diameter—200 meters wider than the previous record-holder， Puerto Ricos 300-meter Arecibo Observatory （though its maximum illuminated aperture is only 30 meters larger）—isnt simply a matter of bragging rights： The bigger the dish， the more gravitational waves it can collect； the fainter their signals， the further back in time they go： 13.7 billion light years， to be precise. FAST has 4，450 panels， double the Arecibo， and， as one scientist put it， if “filled with wine， each of the worlds seven billion inhabitants could fill about five bottles from it.” With this vast astronomical receptacle， researchers hope to explore the deepest secrets of space and， perhaps， answer the most pressing question of all： Are we alone in the universe？ As TWOC arrived in Kedu， we assuredly were not alone： Hundreds of workers were swarming over two large construction sites，页游传奇， from which the familiar sounds of clanking and digging emanated. In the villages of Kedu and Hanglong， a little over five kilometers from the FAST site， another equally eagerly awaited project is going on： the “Pingtang International Radio Science Tourism and Cultural Park，” which locals are calling “the future of tourism” （TWOC visited in March， 2017； the park was scheduled for completion in September， exactly a year after FAST officially went into use）. According to a tourism brochure published by the local government， the park will include a welcome square， an astronomy education park， an “astronomical time village，” the FAST visitor service center， the Galaxy Vortex Tour Central Plaza， a delicacy street， and a four-star resort hotel—this is in addition to the 46 hotels and over 100 restaurants that have been built in the area to cater for the influx of tourism thats already begun flooding in. If tourism and cutting-edge research seem like strange bedfellows， they arent—at least， not for China. In September 2016， when the telescope went into operation， it was hailed by President Xi Jinping as an achievement in “innovation-led development.” Articulated in Chinas 13th Five Year Plan （2016 – 2020）， the phrase summarizes a decade of effort by the Chinese leadership to move past an economy based on manufacturing and low-cost labor. Officials in Pingtang county claims that “Big Tourism，” as generated by FAST， will “push forward local economic and social development” of local villages. “Pushing forward”， or sometimes “pulling forward”， is rural officials version of trickle-down economics： Attracting a flow of national resources and urban capital to their communities， then hoping for the best. Many of those whove lived their whole lives in Kedu do not know what the radio telescope is； nevertheless， theyre encouraged to keep up with this extraordinary pace of development by planting specialty produce， selling local handicrafts， and cooking “eco-friendly farmhouse meals” for visitors. Around town， businesses have been putting up new signage—“Astro Computer Repair，” “Milky Way Renovation Services.”
