The reason why this happens is that physical chemistry can be felt by ordinary people, because physical chemistry is the accumulation of phenomena in daily life. For example, the ground in physics can be touched in daily life. After putting forward this concept, students can immediately imagine what it looks like. Many chemical experiments and chemical substances in chemistry are real. Students can feel a concrete object, so physics and chemistry have an objective basis. For students, it is a better understanding, but mathematics is built entirely through the knowledge built in people's minds, such as formulas, theorems and logical reasoning in mathematics. In fact, it is difficult to find a specific mapping in real life, and it is more about the accumulation of symbols, so it is natural to feel that mathematics is more abstract, which is why mathematics has become the basis of many disciplines, because mathematics can serve many disciplines. Although mathematics is abstract, it can be linked with real life, so when learning mathematics, we must be aware of this difference and importance.
Master scientific learning methods. As long as the learning methods are scientific and efficient, you will have more knowledge for a longer time. Learning is not a painful thing, but a thing to improve yourself step by step. Only by truly understanding the learning methods can we make ourselves more comfortable in the process of learning and never feel the passage of time at all. This is also an important reason why many students can keep their enthusiasm for learning. So there's no need to be too disgusting. As long as you find the right method, you will certainly learn a lot of difficult science knowledge.
