Butterfly effect

The “butterfly effect” is the idea that a tiny change in one place can have a huge effect somewhere else. For example, if a butterfly in the Amazon flaps its wings, it could cause a tornado in Kansas. Yup, that’s right, a tiny butterfly can be responsible for a giant storm! Fun fact: the butterfly effect was first described by meteorologist Edward Lorenz who noticed that tiny changes in the starting conditions of a weather pattern could result in huge differences in the end result.
