Couple of months ago, while attending a seminar, the guest professor started to mention some Swedish inventions. I found myself surprised since among them, the professor mentioned some quotidian ones, such as, the pc mouse, the tetrapak or the zipper. Regarding inventions, there is always controversial opinions about the original inventor. Sometimes, ancient cultures are missed here. For instance, China counts with many inventions used hundred years before Europe. I found a video compilation in Youtube with some of the most famous Swedish inventions. As I already mentioned, the authority for such discoveries is always controversial. When watching the video, notice that the telephone was patented by Alexandre Graham Bell and Lars Magnus Ericsson sells improved version of Bell telephone.
