Alex: I love this museum. This is the room where you can see lots of old inventions. Look! That’s the radio which my great-grandmother told me about. It was made in the 1930s. She remembers the time when everyone used radios like this.
Sami: Does it still work?
Alex: Yes, that’s the button that turns it on. Did you know that the first radio was called a Marconi radio? Guglielmo Marconi is the person who invented it in 1904. It says here that Marconi won the Nobel Prize for his invention in 1909. That was the year when he won it instead of the Wright Brothers.
Sami: Who are they?
Alex: They were the people who invented the aero plane, of course!
Sami: Oh, yes!
Alex: Hey, look at this. It’s an old light bulb. I’ve never seen one like this before.
Sami: Nor have I.
Alex: It says here that the light bulb was invented in 1879 by Thomas Edison in America. That was where he was born. I think that he’s the person whose invention has changed our lives the most.
Sami: I’ve heard of him. Wasn’t he the inventor whose experiment started a fi re on a train? Alex: You’re right! It says here that happened when he was only 15 years old! They made him get off the train after that!
Sami: I’m not surprised!
