Sometimes,when you worry that you may fail an exam,you end up failing.Or during a seating arrangement (安排) in your class,when you are afraid to sit next to someone you don' t like,you end up sharing the desk with him or her.

This is what Murphy' s Law tells us: If things can go wrong,they will go wrong.But is it true?

Of the studies about Murphy' s Law,the most famous one is the buttered toast (烤面包片)phenomenon (现象): One toast with butter falls,it lands butter﹣side down most of the time.

To prove this,Robert Matthews did a lot of experiments with more than 1,000British school kids in 2001.

In the first experiment,each student put a piece of buttered toast on a plate,let it fall off 20times and noted which side it landed on.Of almost 10,000experiments,toast landed butter﹣side down 62percent of the time.

But you may ask: Is it the butter that plays a role? Here comes Matthews' second experiment.

This time,instead of butter,the toast had a letter "B" written on one side.It still landed 58 percent of the time on the B﹣side.

This proved that Murphy' s Law is true: If the toast can land butter﹣side down,it will do so.

Matthews did another experiment.When students threw the toast from a height of 2.5metres,the toast landed butter﹣side down only 47percent of the time.

"Toast lands butter﹣side down because humans aren' t tall enough to let it land any other way," Matthews said.
