Season 1 (7) Challenge to measure physical quantities

With the arrival of spring, the entire campus was bathed in warm light, and Sakura went to the “Advanced Electronics and Electrical Measurement” class. This day’s second lesson focused on “Measurement of basic physical quantities,” and how physical quantities such as pressure, flow velocity, radio waves, force, displacement, and velocity are used in daily life and the development of science and technology. It was an opportunity to deeply explore how we are contributing to the world.

When the class began, the professor began by talking about the basic principles of measurement. He emphasized that all measurements are a process of expressing one physical quantity in another known unit, and that the precision and reproducibility required in that process. Sakura understood that measurement is not just the act of recording numbers, but that there are deep scientific principles and rigorous processes behind it. We learned that selecting the right measuring instrument, accurate calibration, and controlling environmental conditions are essential for accurate measurements.

The explanation about “uncertainty” in measurement provided new insight for Sakura. The professor explained that the uncertainty associated with measurement results determines their reliability, and that their accurate evaluation and reporting is essential to ensuring the accuracy of scientific research. We deeply understood the importance of properly controlling and evaluating the main sources of uncertainty, which include instrument limitations, operator skill, and variations in environmental conditions.

In the second half of the lesson, we will learn how to measure physical quantities such as pressure, flow velocity, and radio waves, and how they are used in various fields of society, such as weather forecasting, medicine, river management, industrial processes, communication technology, and astronomy. I learned about what’s going on. These measurement techniques require advanced skills and knowledge, and the participants also touched on the technical issues involved in achieving highly accurate measurements and the difficulties involved in interpreting measurement results.

In the practical training that was the climax of the class, Sakura formed a team and took on the challenge of measuring flow velocity. Through experiments, I learned about the practical aspects of measurement technology and gained valuable experience that cannot be gained from theory alone. They learned how to evaluate and report measurement uncertainty, and through the analysis and presentation of experimental data, they realized the importance of communication skills and teamwork.

The learnings gained through this class further strengthened Sakura’s foundation as a scientist. They gained a deep understanding of how the measurement of physical quantities contributes to the development of science and technology, and also learned about the handling of uncertainty in measurement and the importance of analyzing and reporting experimental data. This knowledge and experience will be a new step towards future exploration and will serve as a guide to the next challenge. As the spring light illuminates the classroom, Sakura renews her determination to continue her educational journey with the insights she gained from her Advanced Electronic and Electrical Measurement class.
