M: Hello, Mary.
W: Hello, Bob. How did you get up here to the computer room on the sixth floor?
M: Well, by lift, of course.
W: I thought so. Lifts have changed our life.
M: Yes, this invention has had quite an effect on which floor people choose to live on.
W: Well, I suppose before the days of lifts rich people lived on the ground floor and poorer people lived on the top floors and had to use the stairs. Now though it’s the other way round.
M: Do you know when the first lift was invented?
W: I have no idea.
M: It was mathematician Archimedes who invented the first lift in 236 BC. In the Middle Ages there were examples of lifts being used for military purposes. Then they helped to move agricultural products around. They really became very useful in the Industrial Revolution.
W: And there was a wide range of methods used to drive them, too—water and steam power, electricity and so on. Today, tall buildings couldn’t exist without them.
M: But have you noticed why nobody says anything in a lift? Have you ever felt uneasy in a lift, Mary?
W: Actually yes, I have. Just this morning I was standing next to the big boss and neither of us knew what to say to each other.
M: Yes, it’s a strange one, isn’t it? It’s a very anxious experience the time you spend in a lift. I think everyone behaves very differently and awkwardly in a lift. If you have things around you, you take away that awkwardness. We all look at our phones sometimes or look down at the floor. Well, surely it’s better to look at advertisements on the walls.
W: Yes, it is. I think there are so many different ways to improve a lift with light boxes, with moving images, with television screens, it becomes quite exciting for us, and hopefully a little bit more interesting for the people who use lifts every day.
M: Yes, you’re right. By the way, have you heard of the elevator pitch?
W: Yes, I have. It’s something we can do when we’re stuck in a lift with someone.
M: Yes - people say that if you have an idea or product to sell you should be able to sell it - or pitch it - to someone quickly. So in other words, in the time it takes for an elevator - or lift - to reach the top of a building.
W: It’s a good idea if the lift doesn’t break down!
