During one of my vacations, I had the unique pleasure of visiting the house where Thomas Edison lived and worked. It was fascinating to be able to enter the building, now converted into a museum, and simultaneously immerse myself in the world of this legendary inventor associated with so many groundbreaking innovations. The diversity of his inventions, from the light bulb to electrical power generation, is impressive. Since then, a lot has happened. There are many creations and discoveries, most of which undoubtedly have their merits. I find it difficult to single out a specific one.
