And now, Words and Their Stories, from VOA Learning English.
Butterflies are delicate insects. Their wings are thin and can be easily damaged. So, how can a butterfly cause major things to happen?
That is the idea behind the expression butterfly effect.
The theory goes like this: When a butterfly flaps its wings on one side of the planet it can make a small change that, over time, could lead to a big event, like a storm, all the way on the other side of the planet.
The butterfly effect is when very small changes lead to large and unpredictable changes in the future.
For example, let’s say a group of television writers demand higher pay. Their employers refuse. So, the writers go on strike. Then television actors join the strike. Their action forces the television industry to stop production. Then, other businesses that support that industry are affected and so are the towns and communities where those businesses are centered. These changes all resulted from that first demand for higher pay.
A similar expression involves the game of dominoes -- the domino effect.
Dominoes are small rectangular game pieces. One way to play with dominoes is to set them up in a line or pattern. Then you push the domino at the start of the line into the one next to it and so on and so on … until all the dominos fall down. You started the domino effect with your single push of a single domino.
The butterfly effect and domino effect are chain reactions. One thing leads to another. We often say that something sets off a chain reaction.
Here is an example:
The angry argument between the two friends set off a chain reaction of events that no one could have predicted. One thing led to another and now they are enemies.
You can also call this a chain of events. Like butterfly effect and domino effect, one event causes, or triggers, the next one to happen.
Now, let’s hear two friends use some of these expressions:
A: Hey, I’m having the official opening for my bookstore this weekend. You should stop by.
B: I will! And congratulations. You’ve been working on that for a while.
A: Nearly a year. There are so many steps in starting a business.
B: How did you begin?
A: It was a domino effect. As soon as I finished the first thing, the next thing to do became clear, and the next and the next.
B: Sounds like starting that chain of events was important.
A: Absolutely.
B: As a writer, did you always want to own a bookstore?
A: It’s funny you ask. When I was little, my friend’s parents owned a bookstore. I’d hang out there for hours!
B: It’s like the butterfly effect. Something that happened a long time ago, affected your future today.
A: Hmm, that sounds like a good story to write.
And that’s Words and Their Stories.
