20+ high speed trains in a train depot in Wuhan

High-speed trains in Wuhan

That (…) picture is so serious. Once upon a time, the Dow Jones industrial average was a composite metric designed to roughly characterize the rail industry, including steel production, machining and manufacture, real estate, and use. The health of that industry was found to be predictive of the health of the entire country, and although the DJIA shifted from rail, it is still predictive of nationwide economic health.

China, in my eyes, just proved how far ahead they are – and my jaw is on the floor. Those trains represent so much. It’s not merely that they exist – and all of the economic activity inherent in making them exist – but now that they exist, they are an engine of productivity.

Histomap of world history

I think I would like to have this map of world history:
histomap.png
“Not a map really, but a 5-foot-high chart showing in one glance 4,000 years of human history on a global scale. Thirty years ago I saw this on the wall of someone’s dorm room and it flipped me out then, and every time I’ve seen it since. Its beauty is how Mr. Sparks divies up world power (somewhat crudely) into its main factions graphed in each increment of fifty years since 2000 B.C.E. Different civilizations are color-coded so one can easily trace the flow and ebb of culture over the centuries.”

Unfortunately, it is out of sale – but luckily there’s still a high quality mirror online.
