For many reasons, mostly political but partly ethical, I do not use Google, Facebook, Twitter. They practice corrupt business policies, while targeting conservative websites for censoring, facts repeatedly confirmed by news stories and by my sense that Facebook has taken action to prevent my readers from recommending Behind the Black to their friends.
Thus, I must have your direct support to keep this webpage alive. Not only does the money pay the bills, it gives me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.

An evening pause: More proof that modern engineering can make almost anything seem easy.

Thats an awful big and complex machine, way up high, and a lot of guys all depending that nothing fails, like the grade of concrete being poured in those columns by some Chinese contractor. Its cool, but it makes me nervous.
Look on the bright side: if it doesn’t collapse during the erection, you’d feel safe driving a car over it when it’s done.
It would be even cooler if they could do this on a curved section.
Not a safety harness in sight. Here in BC the authorities would poop nukes. Send in the grief counsellors.
I agree about the safety measures. One thing I’ve noticed about Chinese construction practices is that little attention is paid to worker safety. But when you’ve got 2 billion people to choose from, and the State protects you from liability, why worry? On the other hand, I was looking at the process from a continuous feed standpoint, sort of like a TBM.
