Why a Physics and Math Major is Valuable for Electrical Engineering

For one thing, physics and mathematics form the bedrock of any electrical engineering program. While electrical engineering is often seen as a practical, hands-on field, a strong foundation in these subjects is essential for understanding the fundamental principles and tools used in circuit analysis and design.

The Interplay Between Mathematics and Electrical Engineering

Mathematics is the language of physics, and it serves as a crucial tool for electrical engineers in circuit analysis and design. Without a solid grasp of mathematical concepts, it would be nearly impossible to comprehend the underlying principles that govern electrical systems.

My journey in electrical engineering began with a heavy emphasis on physics and mathematics before I started my formal electrical and electronics courses in my third year. These early courses provided a fertile ground for understanding the intricate relationships between physical phenomena and their mathematical representations.

Setting the Foundation for Advanced Studies

The knowledge gained from a physics and math major can greatly prepare you for advanced studies, such as doctoral research in fields related to electrical engineering. For instance, having a strong foundation in these subjects can enable you to tackle complex research projects that require a deep understanding of both theoretical and practical aspects.

The Power of Multidisciplinary Knowledge

Understanding the boundaries of overlapping disciplines can be incredibly powerful. A physicist might get overwhelmed by the details of electrons and holes when attempting to design a simple transistor circuit, while an electrical engineer can see the bigger picture—knowing that a small input current results in a larger output current.

Each discipline requires a different mindset and approach. For example, engineers often need to generalize and abstract complex systems to simpler models, a skill that is much less emphasized in purely theoretical physics. Conversely, physicists tend to focus on the intricate details that underpin the behavior of matter and energy.

However, the ability to wear different hats and switch between these perspectives is what enables true innovation and creativity. This interdisciplinary mindset is invaluable in the modern field of electrical engineering, where seamless integration of mechanical, electrical, and applied physics concepts is essential.

The Roadmap to Mastery

Your journey in electrical engineering can either follow a traditional path or a more self-directed route. For those who start learning at a young age, like me at the age of 9, the path can be easy and intuitive. I didn't take a single formal electrical engineering class but instead learned through practical problem-solving and trial and error.

While theoretical knowledge is undoubtedly important, hands-on experience and problem-solving are equally crucial. As you progress, you will encounter increasingly complex problems that require a deeper understanding of both mathematics and physics. The more knowledge you accumulate, the more capable you will be in devising innovative solutions and pushing the boundaries of what is currently known.

Beyond the Book

A true engineer is not one who merely follows the steps laid out in a textbook. While it's important to learn from others, the real value comes from going beyond the existing knowledge and contributing something novel. This might involve developing new technologies, exploring uncharted territories, or finding more efficient ways to solve problems that have long been considered difficult.

The power to innovate lies in your head, and it is the ability to synthesize and apply knowledge from various disciplines that sets you apart. So, whether you are a budding electrical engineer or a seasoned professional, investing in a strong foundation in physics and mathematics is an invaluable tool for your journey in this exciting and dynamic field.
