1. Sensors Sensors can detect physical quantities such as force, temperature, light, sound, and chemical components, and convert them into a physical quantity (usually electrical quantities like current or voltage) that is easy to transmit and process, or switch a circuit on or off. By converting non-electrical quantities into electrical quantities, measurement, transmission, processing, and … Read more
The core of solid-state physics is band theory, which classifies the crystalline world into two categories: “insulators” and “conductors”. Then, to fill in the gaps for semiconductor applications at room temperature, the concept of “semiconductors” was added. This is now common knowledge taught in high schools, marking the establishment of band theory.^_^. Of course, band … Read more
Most people in society would agree that among the major disciplines of natural sciences, mathematics and physics are the most authoritative, precise, and beautiful. The experience of authority is not easy to grasp, but as time spent in these fields increases, the understanding deepens. The authority of physics is reflected in the simplicity, effectiveness, and … Read more
