Oh it's my favorite time of the week again on HN! I truly love these blogs. Someone last week posted this[1] documentary which I think more people should see in connection with this series. But I'm still collecting questions, which I may take to Quora or SO at some point but I'd love to know how did we get started with (i.e. discover) this process and how does it differ from steel. Apparently we will learn about the latter in the next blog though, so I can wait on that. [1]. https://www.youtube.com/watch?v=RuCnZClWwpQ https://www.youtube.com/watch?v=RuCnZClWwpQ
