Tuesday Tweets -- “rapid unplanned disassembly“ edition

The hyperloop achieved an impressive top speed shortly before “rapid unplanned disassembly“. You could get the same outcome much more cheaply by falling off of a tall building. @TUM_Hyperloop https://t.co/tjE9tAxm0N

“Rapid unplanned disassembly“ is very likely to cause a loss of cabin pressure.@alon_levy @trnsprtst

Nice example of how mobile carriers are using and selling location data, which had gotten less attention than "big tech" https://t.co/EBoobJj7vb

I think Lee is underplaying the role that the huge, broad-based spikes in the late 19th Century and post-war era were in forming the idea of the exponential progress curve (and how resilient the belief has been in the face of conflicting data). 

It's interesting to imagine a world where humanity never invented the transistor and therefore never had a digital revolution. In that world, the obvious interpretation of economic history would be that the discovery of fossil fuels gave humanity a one-time growth spurt.

I've been meaning to do a post on indicators that the standard political model may be heading for a rough patch.

Also want to come back to this.

We've been seeing the same thing in a number of supposedly red States. Ideologically they are moving to the center, perhaps even the left, on many ideological issues while becoming more Republican at the same time https://t.co/rt67z1gO0i

Silver is having a good run.

Not that you should expect better from one of those "Despite Thing, Voters in Trump Country Still Love Trump!" articles, but this polling showing him down 2 in Obama-Trump counties would be quite *bad* for Trump. He won Macomb County by 12 points in 2016. https://t.co/TePjzoDeJ1 pic.twitter.com/9T9ydanMeA
