China and Science



Chinese schoolchildren are still taught to think of this general period as the “century of humiliation,” the nadir of China’s long fall from its Ming-dynasty peak. Back when the ancient observatory was built, China could rightly regard itself as the lone survivor of the great Bronze Age civilizations, a class that included the Babylonians, the Mycenaeans, and even the ancient Egyptians. Western poets came to regard the latter’s ruins as Ozymandian proof that nothing lasted. But China had lasted. Its emperors presided over the planet’s largest complex social organization. They commanded tribute payments from China’s neighbors, whose rulers sent envoys to Beijing to perform a baroque face-to-the-ground bowing ceremony for the emperors’ pleasure.

In the first volume of his landmark series, Science and Civilisation in China, published in 1954, the British Sinologist Joseph Needham asked why the scientific revolution hadn’t happened in China, given its sophisticated intellectual meritocracy, based on exams that measured citizens’ mastery of classical texts. This inquiry has since become known as the “Needham Question,” though Voltaire too had wondered why Chinese mathematics stalled out at geometry, and why it was the Jesuits who brought the gospel of Copernicus into China, and not the other way around. He blamed the Confucian emphasis on tradition. Other historians blamed China’s remarkably stable politics. A large landmass ruled by long dynasties may have encouraged less technical dynamism than did Europe, where more than 10 polities were crammed into a small area, triggering constant conflict. As we know from the Manhattan Project, the stakes of war have a way of sharpening the scientific mind.

Still others have accused premodern China of insufficient curiosity about life beyond its borders. (Notably, there seems to have been very little speculation in China about extraterrestrial life before the modern era.) This lack of curiosity is said to explain why China pressed pause on naval innovation during the late Middle Ages, right at the dawn of Europe’s age of exploration, when the Western imperial powers were looking fondly back through the medieval fog to seafaring Athens.

Whatever the reason, China paid a dear price for slipping behind the West in science and technology. In 1793, King George III stocked a ship with the British empire’s most dazzling inventions and sent it to China, only to be rebuffed by its emperor, who said he had “no use” for England’s trinkets. Nearly half a century later, Britain returned to China, seeking buyers for India’s opium harvest. China’s emperor again declined, and instead cracked down on the local sale of the drug, culminating in the seizure and flamboyant seaside destruction of 2 million pounds of British-owned opium. Her Majesty’s Navy responded with the full force of its futuristic technology, running ironclad steamships straight up the Yangtze, sinking Chinese junk boats, until the emperor had no choice but to sign the first of the “unequal treaties” that ceded Hong Kong, along with five other ports, to British jurisdiction. After the French made a colony of Vietnam, they joined in this “slicing of the Chinese melon,” as it came to be called, along with the Germans, who occupied a significant portion of Shandong province.

Meanwhile Japan, a “little brother” as far as China was concerned, responded to Western aggression by quickly modernizing its navy, such that in 1894, it was able to sink most of China’s fleet in a single battle, taking Taiwan as the spoils. And this was just a prelude to Japan’s brutal mid-20th-century invasion of China, part of a larger campaign of civilizational expansion that aimed to spread Japanese power to the entire Pacific, a campaign that was largely successful, until it encountered the United States and its city-leveling nukes.

China’s humiliations multiplied with America’s rise. After sending 200,000 laborers to the Western Front in support of the Allied war effort during World War I, Chinese diplomats arrived at Versailles expecting something of a restoration, or at least relief from the unequal treaties. Instead, China was seated at the kids’ table with Greece and Siam, while the Western powers carved up the globe.

Only recently has China regained its geopolitical might, after opening to the world during Deng Xiaoping’s 1980s reign. Deng evinced a near-religious reverence for science and technology, a sentiment that is undimmed in Chinese culture today. The country is on pace to outspend the United States on R&D this decade, but the quality of its research varies a great deal. According to one study, even at China’s most prestigious academic institutions, a third of scientific papers are faked or plagiarized. Knowing how poorly the country’s journals are regarded, Chinese universities are reportedly offering bonuses of up to six figures to researchers who publish in Western journals.

It remains an open question whether Chinese science will ever catch up with that of the West without a bedrock political commitment to the free exchange of ideas. China’s persecution of dissident scientists began under Mao, whose ideologues branded Einstein’s theories “counterrevolutionary.” But it did not end with him. Even in the absence of overt persecution, the country’s “great firewall” handicaps Chinese scientists, who have difficulty accessing data published abroad.

China has learned the hard way that spectacular scientific achievements confer prestige upon nations. The “Celestial Kingdom” looked on from the sidelines as Russia flung the first satellite and human being into space, and then again when American astronauts spiked the Stars and Stripes into the lunar crust.

China has largely focused on the applied sciences. It built the world’s fastest supercomputer, spent heavily on medical research, and planted a “great green wall” of forests in its northwest as a last-ditch effort to halt the Gobi Desert’s spread. Now China is bringing its immense resources to bear on the fundamental sciences. The country plans to build an atom smasher that will conjure thousands of “god particles” out of the ether, in the same time it took cern’s Large Hadron Collider to strain out a handful. It is also eyeing Mars. In the technopoetic idiom of the 21st century, nothing would symbolize China’s rise like a high-definition shot of a Chinese astronaut setting foot on the red planet.
