Mathematics has many real-life applications, and one of them is creating and altering the shape of objects. Forming a shape requires various measurement parameters such as length, area, and volume. Now, all our measuring devices are completely straight, meaning they can measure length accurately for straight-line objects. But when it comes to curved shapes, we lack measuring tools that can help determine their length, area, or volume. This led to several major problems in making any curved shape objects. Measuring the parameters of any object with even a slight curve, or any curvature at all, had become extremely difficult.
So, a constant parameter was invented to solve these problems. That constant parameter was named Pi(𝝿). It is an irrational number, and its discovery is linked to many fascinating facts. For instance, its exact value has never been calculated today, and we always use its approximate value. However, I won’t discuss all those details right now. Instead, I’ll focus on its applications. Because the value of Pi(𝝿) gives us the measure of any curved shape with an accuracy of about 99%.
Let’s discuss a few real-world applications. We all wear watches on our wrists. If Pi(𝝿) had not been invented, then inventing a watch would have been nearly impossible. This is because the hands of a watch move in a circular path, and the lengths of the hour and minute hands vary. Without Pi(𝝿), we could never have designed the shape of a watch and we would also not be able to measure the time accurately.
Moreover, Pi(𝝿) is essential wherever curved shapes are involved. Another major application of Pi(𝝿) is in the creation of medical devices used in human body surgeries. The human body faces various problems, and sometimes, surgery is required to fix them. The devices used in these surgeries have highly complex shapes and designs. Designing such complex structures without the help of Pi(𝝿) is completely impossible to imagine.
There are so many other superb applications of Pi(𝝿) in the modern world. Such as a GPS device or GOOGLE MAPS cannot work without the help of Pi(𝝿). Because they use latitude and longitude measures to complete their work, and such measurements can be taken accurately for a spherical-shaped body of earth only with the help of Pi(𝝿).
Now, I will talk about a very major application of Pi(𝝿). Suppose we came to know that a natural disaster like an earthquake, cyclone, or tsunami is about to occur in any region of the world, then for the complete analysis of the natural disaster through modern technology, a large mathematical calculation is required, and for these calculations, we need Pi(𝝿). For such analysis, we need to study the rotational motion and circulation motion of air and water. For this, we again need Pi(𝝿). for rotational and circular motion, we need to measure curvature lengths, which are angular and measured in degrees, and it is very difficult to make any calculation when the measuring units are in degrees. So we convert the degree measurement parameters into radians. It helps in making easy calculations for such complicated measurements, and the measurement in radians is possible only with the help of Pi(𝝿).
So learn the applications of Pi(𝝿) in solving real-life problems. But it requires a lot of practice, and practice comes from continuously solving questions. That is why, on this website, you will find numerous practice questions with their detailed solutions related to probability and other topics of mathematics. These practice questions will be very useful for various competitive exams like IITJEE, GATE, CAT, GMAT, etc. So, find questions according to your topic and practice as much as you want.
