Best video so far of the two massive explosions in Tianjin


From wiki:

On 12 August 2015, at least two explosions within 30 seconds of each other occurred at a container storage station at the Port of Tianjin in the Binhai New Area of Tianjin, China.[4][5] The cause of the explosions was not immediately known, but initial reports pointed to an industrial accident.[5] Chinese state media said that at least the initial blast was from unknown hazardous materials in shipping containers at a plant warehouse owned by Ruihai Logistics,[6] a firm specializing in handling hazardous materials.

 [...]

 Several reports stated that at least 71 people were severely injured, and more than 50 killed.

How Do Bikes Stay Up?

We discussed this a while ago, I don't know the supported arguments anymore, but it turns out we were both wrong/right. It's complicated and not exactly known.


A nice quote from the brilliant physicist Freeman Dyson:
You can't possibly get a good technology going without an enormous number of failures. It's a universal rule. If you look at bicycles, there were thousands of weird models built and tried before they found the one that really worked. You could never design a bicycle theoretically. Even now, after we've been building them for 100 years, it's very difficult to understand just why a bicycle works – it's even difficult to formulate it as a mathematical problem. But just by trial and error, we found out how to do it, and the error was essential.
This is also really interesting, a bicycle that steers in reverse and is only possible to control after a lot of practice:
