So I was surprised to hear that the port of Prince Rupert has the third largest port in Canada, ranked above even Halifax ( 5 Largest Major Ports in Canada | Canada's Shipping Ports : Dolphin Delivery ). The city (town really) has a population of around 12,000, though I'm not sure if there's an increasing trend there lately. Shipments are heavily reliant on CN Rail's tracks, as you can imagine there is little local demand with poorly connected road infrastructure. I guess fishing and forestry make up the rest of the economic share of the region. My question is, why hasn't there been a massive population boom or economic boom as a result of this huge port capacity? For example, Prince Rupert is one of the worst regions for intergenerational income mobility in Canada ( A tale of two Canadas: Where you grow up affects your income in adulthood - The Globe and Mail ). Even cities like Anchorage, which are somewhat isolated, are more populated, diverse and prosperous (though for different reasons - I'm guessing not so much as a major shipping stop but due to oil and gas). Why isn't the economic output from the port being properly reinvested in the local community?
From a material science perspective, what's distinct about a material that can form a prince Rupert drop and what conditions are needed to find out how to make them?
Has anyone made comparisons between different glass types or molten crystal like sapphire? Are there organic materials that "temper" when dropped into liquid nitrogen that behave similar? Can they be made from metal glass?
