No, we are not talking about the movie by Ashton Kutcher. We are going to talk about the Butterfly Effect which is a concept in chaos theory, which says
A flap of butterfly's wings in Brazil can set out a tornado in Texas.
More generally, few insignificant random events can cause a big impact. This phenomena occur a lot in our daily life. But perhaps, it is referred to as fate, rather than the Butterfly Effect. For example, had Bruce Willis not gone to at attend an Olympic event in 1984, he might have not been a star today, or had you not gone to study abroad, you might have not found the love of your life.
