Physics Fundamentals: Exploring Scales and Scientific Methods

This lecture introduces the fundamental concepts of physics, focusing on the laws of nature and the scientific method. The instructor discusses the importance of understanding physics in the context of life sciences, emphasizing the need for a solid foundation in scientific principles. The lecture begins by situating physics within various spatial scales, from the vastness of the universe to the infinitesimal size of subatomic particles. The instructor illustrates the scientific method through a practical example, testing a common theory about measurement. The discussion includes the significance of measurement uncertainty and the necessity of experimental verification in science. The lecture also outlines the organization of the course, including the structure of classes and exercises, and highlights the importance of using the International System of Units (SI) for measurements. By the end of the session, students gain insights into the relationship between theory and experimentation, preparing them for further exploration in physics and its applications in the sciences.
