Mind Blowing Machines That Are At Another Level

The first machine tools date back to 1200 B.C.E. Many new mechanisms have been invented, and now they're an essential part of our industry. It's hard to imagine some everyday processes being done without them. Nowadays, machines are more evolved than ever and help in more ways than we can count. I liked that stuff, like with the pan and that Metal thing before that. Pretty nice and interesting how it is made and how people would even get the Idea for all the things is beyond comprehension how to take it from literally nothing and then see where you can have material for it and that it would actually do a specific task or like more tasks. The world is quite strange really if one goes into the thoughts of how they could Think of these things like Photo cameras, like, how did they think a person or people could become also visible on? Whatever they thought right and then just out of the blue think like, say like, this material will be able to do it without any idea in advance on it. The welding at 2.09 is not the welding described by the text. The video is rotation friction welding, where the friction is between the two round pieces being joined and there is no tool piece in the weld. Friction stir welding is where a rotating tool is forced along a joint creating heat and mixing the two parts being joined.
