________ Take the following as examples.

Traffic solutions

Do you know how the timing of traffic lights is decided to avoid traffic jams? Traffic engineers use special math models to set these timings. They are called traffic flow (流量) models. They consider the number of cars, zebra crossing, the time of day, and any events happening. With these models, engineers can work out the best timings for traffic lights in the city. Moreover, researchers are always trying to make these models better to prevent traffic jams more effectively.

Literature

UK scientist Sarah Hart presents some interesting thoughts about “three”. She said that the number has a special influence on Western literature and languages.

According to Hart, three sticks can create a triangle (三角形), the most basic stable (稳定的) structure. With “a sense of strength and completeness (完整)”, she said, “three” becomes common in our languages. Many common expressions in English come as three words, such as “ready, set, go”. Some nursery (童谣) rhymes have a word repeated three times, such as “row, row, row your boat”. In stories, there are usually three main characters, such as Harry, Ron and Hermione in the Harry Potter series. For a series of novels, there are usually three books rather than four.

Weather prediction

As we have a further understanding of nature, we come to realize that it can be explained through math. Math plays an important role in weather prediction.

Every day, supercomputers process thousands of observations from Earth, including air pressure, water levels, temperature, and wind speed. These observations are presented in data (数据). Using different mathematical methods, these supercomputers analyze (分析) the data and predict global weather patterns.

So, don’t make math just appear on students’ homework.
