Cognition – The way we think, learn, remember, and solve problems. It’s all the mental work our brain does. For example, when you study for a test, plan your day, or figure out how to fix something, that’s cognition.
Metacognition – Thinking about your own thinking. It helps you notice how you solve problems or learn so you can improve. For example, before doing homework, you might plan your approach or check if your solution makes sense.

Classical and Quantum Free Electron Theory Principles
1. Classical Free Electron Theory and Assumptions
The classical free electron theory explains the electrical behavior of metals by assuming that a metal consists of a lattice of positive ions surrounded by a gas of free electrons. These electrons move freely inside the metal and obey classical Newtonian mechanics. Electron–electron interactions are neglected, and collisions occur only with fixed ions. The electrons follow Maxwell–Boltzmann statistics, and an applied electric field causes a net
