A thread: why arithmetic numeracy is heavily under-appreciated and why it should not. "China camped millions of Uyghurs in XJ!" OK, let's play a bit of math game. How much room is needed to house, say, one million people? 20 sqm. Let's say it has four double bunkers, able to

house 8 people. To house one million people, we need 2.5mil sqm space. According to "credible sources", one such typical "concentration camp" includes 10k sqm of living area. See the problem here? To house one million people, you need 250 of such facilities. Xinjiang has 14

cities. The amount of money, personnel, resources.. needed to manage this kind of project? The time involved in building them up? The possibility to hide them away from the public scrutiny and satellite imaging? According to "credible sources", 30 of them have been identified.

Great! Only 220 more to "find". Another little math game. XJ has 10mil Uyghur citizens. Let's say we stick to the "low" number: one million is being held in camps. That also means since around five years ago, it is likely that each year this similar number of people have been

held. Adding their relatives into the equation, it soon becomes clear that 50% or even more of XJ Uyghurs have been held in camps at some point in the last five years. How does this work, especially in big Uyghur cities such as Kashgar, where 90%+ of the population are Uyghurs?

According to the 3.5% rule, in any society if 3.5% of the population have discontent, an uprising is very likely. Imagine what must be going on in Kashgar until.. wait, no such thing there! What's wrong? 2) HK's 2mil protesters. How many people can a cubic of 1sqm hold?

In a walking parade, at most 2-3 people. HK's wider streets have 4 lanes in total, or measure at around 40 meters. The entire marching length is 3.5km. That gives a total land space of 140k sqm: at any given point of time, a fully packed march gives you at most 400k people.

And I do encourage you to try standing in a cubic meter with two other adults to get a feel. And then try walking together, in that square. Must be real comfy. Standing in that density to complete a 3.5km march would require at least 2 hours. AND we need the previous batch of
