This was a super fun read, and it felt nice to take the time to carefully read it to understand the very complex processes it was describing. That said, can someone explain how the pigtail accomplishes the following?: > "The crystals grow in a straight line in the direction that the mould is being withdrawn, but because of the pigtail’s twisted shape, all but the fastest-growing crystals are eliminated."
I'm not a car person but you can't help but feel a shiver when you see a car like that. The engines where the same as the ones they used in the Spitfire fighter planes during WW2 (6.5 liter v8!), full white leather interior, a retractable partition between the passengers and the chauffeur.

I had the chance recently to see the Mayor of the City of London's (the strange city-within-a-city bit of London) two Rolls Royce's they keep for formal occasions up close. They are super rare (only ~400 ever made), worth a whole lot of money and looked amazing . I'm not a car person but you can't help but feel a shiver when you see a car like that.
