China thinks it invented everything.

There is no evidence to suggest that China had any scientific evaluation of chemistry other than trial and error until such practices were introduced to them. Gunpowder was not invented but discovered by chance and improved through trial and error and most of these improvements and the development of the first firearms were made in the middle east.

They didn't invent woodblocks and thus weren't the first to print using woodblocks. Printing with woodblocks is not the same as printing with a printing press.

The chinese did invent a way of using wood pulp to make paper, but this is just 1 material in a long line of materials which were discovered could be used to make paper. The first material was papyrus, thus only the ancient Egyptians can claim the title "invented paper".

The compass was invented by the Olmecs before 1000 BC and it may have been invented seperately later by europeans. For 100s of years the compass never entered the middle east, yet just a few decades after it's first appearance in europe in 1180 the muslims began to use it. The Chinese can neither claim they invented it first or that they gave it to the rest of the world, only that they invented it seperately.

China is a rich ancient culture and has nothing to be ashamed of so I can see the allure to people who have no achievements of their own to claim the achievements of "their" culture. As depressing as it might be to see people stoop to this level of delusion to appease their anxieties, there is nothing more ridiculous than having to lie about your culture to aggrandize yourself more. There are no further depths of self pity.

Indeed. 97% of the most significant figures in science between 800 BC and 1950 AD were Westerners.

The trend continues today, although it's inevitable the East will catch up (to a certain extent) as they become more wealthy and educated. (Something they could not do without the West discovering the technological and economic knowledge, and investing in Asia). Since 2000, the UK has won 12 nobel prizes. Japan, with roughly equal GDP and living standards and twice the population has won just 4. This is despite Japan having a mean IQ about 4-5 points higher. Jews are the only group with an IQ higher than whites who actually "achieve" in proportions you would expect from their scores.

Achievement at the highest level is a difficult thing to explain, but from the emperical data whites and Jews are more prone to great achievements than Asians.
