Why Some People Believe They Never Used the Pythagorean Theorem in the Real World
Upon finishing school, it is common to hear that some individuals confidently state they have never utilized the Pythagorean theorem in the real world. This article delves into the reasons behind such claims and explores the broader implications of these statements on mathematics education and real-world applications.
The Context of School Completion
The term upon finishing school can mean different things to different people. For some, it signifies the moment of graduation, while for others, it might denote the end of a particular grade level. Those who have just graduated may lack extensive real-world experience, leading them to make sweeping generalizations about their past.
Often, people emphasize such points to prove a particular assertion. For instance, if someone casually remarks they have never used the Pythagorean theorem, it might not elicit much response. However, if they emphatically state they have never used it, it could signal a more profound aversion or misunderstanding of the concept.
The Truth of the Matter
Most people, even those with a solid mathematical background, may rarely, if ever, utilize the Pythagorean theorem in their daily lives. I myself majored in math at the undergraduate level, yet I cannot recall any instances of applying the theorem to solve real-world problems. The basic principles of arithmetic (addition, subtraction, multiplication, and division) are often sufficient to manage everyday tasks.
The Psychology Behind the Claim
Some individuals enjoy proving that they are capable of disregarding even the simplest concepts. The Pythagorean theorem, with its complex name and specific application, can be particularly easy to overlook in favor of more straightforward methods. For example, measuring a distance directly might be quicker than using the theorem. Additionally, the quadratic formula, which includes squares and square roots, might contribute to the confusion, especially if the underlying concepts are not clearly explained.
The Disparity in Language and Mathematics
While speaking a native language correctly is essential in most professions, the same cannot be said for mathematics. People often take pride in announcing that they never use mathematics in their daily lives. This attitude overlooks the critical role of mathematics in understanding our modern world. As James Burke aptly demonstrated in his television series Connections, our current technologies and systems are deeply rooted in mathematical principles.
Mathematics is not just about solving abstract problems; it is a fundamental tool for understanding the world around us. A course in the history of science and mathematics could provide a more profound appreciation for these concepts, fostering a better connection between theoretical knowledge and practical applications.
Conclusion
The idea that one has never used the Pythagorean theorem in the real world can stem from a mix of personal experiences, psychological factors, and a broader attitude towards mathematics. While these claims might reflect a genuine lack of specific applications, they also highlight the importance of making mathematics more accessible and relevant in everyday life. By understanding the historical and practical significance of mathematical concepts, we can bridge the gap between theory and practice, ultimately enriching our understanding of the world.
