Question

Simple things that are super complex

● Defining (定義) the word “the” is really difficult.

The word “the” is one of the most common words in the English language and most of us have probably never stopped to think about how strange of a word it actually is. A dictionary lists more than twenty different ways the word can be used in a sentence correctly, which makes an exact definition of the word much more difficult to explain.

● There’s no theory (理論) accepted by everyone on how bikes work.

Bicycles have existed (存在) for over 100 years, and scientists have been discussing about how exactly they work, or more specifically, how they stay upright, almost since they were first invented. But there’s no exact answer to it. And because bicycle dynamics (動態(tài)) isn’t exactly an area of science into which researchers like to spend time, it’s highly impossible that we’ll know for sure anytime soon.

● Yawning (打哈欠)

Yawning is a puzzling phenomenon (現(xiàn)象). Even that act of talking about it is simple enough to make some people do it. There is really no other bodily function quite like it. In fact, there is no theory for we yawn, which is agreed upon by everyone. As for why yawning is contagious (傳染), no one knows that either.
