Hi Tamara
From a pure software engineering perspective I would say, no. You don't need physics to do software engineering, but it does help. A lot of software developers don't think about the physical world when they are writing software. Given limits like the speed of light, it takes a finite time to move a body of data from point A to point B. If they expect it to happen instantaneously then their software isn't going to work as well as it could. An understanding of physics and those sorts of limitations is always helpful I think, but certainly not mandatory for a software engineer.

Physics does not play a significant role in most traditional software engineering roles, which typically focus on developing software applications, designing user interfaces, building databases, managing software projects, and optimizing algorithms. These roles require a deep understanding of computer science concepts, programming languages, software development methodologies, and problem-solving skills rather than physics. However, if you are interested in specialized fields like quantum computing, physics becomes significantly more important. Quantum computing represents a revolutionary approach to computation, fundamentally different from classical computing. While traditional computers use bits as the basic unit of information, either 0 or 1, quantum computers use quantum bits or qubits. Qubits can exist in multiple states simultaneously (thanks to the principles of superposition). They can be entangled with one another, allowing quantum computers to perform complex calculations at speeds exponentially faster than classical computers for specific tasks. Let me break this down for you so you understand the role of physics in this type of software engineering.
Physics does not play a significant role in most traditional software engineering roles. These roles typically focus on the following areas:
Software Development involves writing code to build software applications, ranging from simple programs to complex systems like enterprise software. Engineers work with programming languages (such as Python, Java, or C++) and follow software development methodologies (like Agile or DevOps) to create, test, and maintain software products. For example, a software engineer developing a mobile app for e-commerce does not require an understanding of physics to perform their job.
Database Management: Software engineers often design and manage databases, ensuring that data is stored efficiently and can be retrieved quickly. This involves working with database management systems (DBMS) like SQL, PostgreSQL, or MongoDB. The focus here is on data structures, optimization, and query performance, which are more aligned with computer science than physics.
User Interface (UI) and User Experience (UX) Design: In roles focused on UI/UX, engineers design user-friendly and aesthetically pleasing interfaces. This requires knowledge of design principles, human-computer interaction, and often some front-end development skills (like HTML, CSS, and JavaScript). Again, physics plays little to no role in these tasks.
Software Testing and Quality Assurance: Engineers in this area focus on ensuring that software operates as intended, identifying bugs, and improving performance. They use testing frameworks and methodologies to validate software functionality. For example, a QA engineer writing test cases for a web application would not need to apply any physics concepts.
Note that these are the traditional methods; if you want to get ahead of the game, you would like to get into quantum computing, which needs physics or at least the quantum mechanics side. While physics is not essential for traditional software engineering roles, it becomes critically important in quantum computing. Quantum computing is an emerging technology that leverages the principles of quantum mechanics—a branch of physics that deals with the behavior of particles at the atomic and subatomic levels—to perform computations.
A quantum computer differs fundamentally from a classical computer:
Classical Computers Use bits as the basic unit of information, where each bit can be either 0 or 1. They perform computations by processing these bits sequentially or parallelly.
Quantum Computers: Use quantum bits, or qubits, which can exist in multiple states simultaneously due to a quantum phenomenon called superposition. Unlike classical bits, qubits can represent both 0 and 1 at the same time, which allows quantum computers to process a vast number of possibilities simultaneously.
Example: Suppose you have to solve a problem that requires checking multiple data combinations (like finding the shortest path in a network). A classical computer might have to check each path one by one. In contrast, a quantum computer can explore all possible paths simultaneously, thanks to superposition, drastically reducing the computation time for specific problems.
Entanglement: Another quantum principle is entanglement, where the state of one qubit is directly related to the state of another, no matter the distance between them. This property allows quantum computers to perform complex computations with a level of parallelism that classical computers cannot achieve.
Example: In cryptography, quantum computers can potentially break traditional encryption methods by factoring large numbers exponentially faster than classical computers, thanks to entanglement and superposition.
Quantum computing is deeply rooted in the principles of quantum mechanics, a branch of physics. Here are a few key concepts from physics that are crucial in quantum computing. As mentioned earlier, superposition allows qubits to exist in multiple states simultaneously. Understanding the mathematics and physics behind superposition is essential for developing quantum algorithms and understanding how quantum computers process information. An example of this would be the quantum algorithm, Grover's algorithm, which is used for searching unsorted databases and leverages superposition to search the database in significantly fewer steps than a classical algorithm would require. Another aspect is Quantum Entanglement. This phenomenon is used in quantum computing to link qubits so that one qubit's state instantly affects another's state, regardless of distance. It is crucial for certain quantum algorithms and for the development of quantum networks.
An example of this would be quantum teleportation, in which information about the state of a qubit is transmitted from one location to another using entanglement without physically moving the qubit itself. One last aspect is Quantum Tunneling. Quantum computers can exploit quantum tunneling to solve optimization problems more efficiently. This phenomenon allows particles to pass through energy barriers that would be insurmountable in classical physics. An example would be quantum annealing, a quantum computing technique used by companies like D-Wave, which leverages quantum tunneling to find the optimal solutions for complex optimization problems that classical computers struggle to solve.
If you are interested in pursuing a career in quantum software engineering, a strong foundation in physics, particularly quantum mechanics, is crucial. Developing algorithms for quantum computers, understanding how quantum gates operate, and optimizing quantum circuits require knowledge of the underlying physical principles. An example of a Quantum Software Engineering Role is a quantum software engineer who might work on developing quantum algorithms for machine learning. To do this, they would need to understand quantum mechanics and machine learning principles to create algorithms that can be executed on quantum computers.
Suppose you are studying software engineering and are primarily interested in traditional software development roles (such as web development, app development, or database management). In that case, you may not need to take advanced physics courses. However, introductory physics courses can still benefit general knowledge and problem-solving skills. On the other hand, if you are fascinated by the potential of quantum computing and want to work in this cutting-edge field, taking courses in physics—especially quantum mechanics—would be highly recommended. These courses will provide the necessary background to understand how quantum computers work and how to develop software for them. In summary, while physics is not a significant requirement for most software engineering roles, it becomes essential if you wish to explore the rapidly growing field of quantum computing. Understanding the physical principles that underlie quantum mechanics will enable you to contribute to this advanced area of technology, where the boundaries of computation are being pushed to new limits.

Sahida’s Answer
Physics does not play a major role in software engineering itself, which primarily focuses on programming, software design, algorithms, and systems development. However, there are certain areas within computer science and engineering where physics concepts might be relevant:
Where Physics Might Be Relevant in Software Engineering:
Computer Graphics and Game Development:
Physics is essential in creating realistic simulations, animations, and rendering in video games or virtual environments.
Embedded Systems:
If you work with hardware-software integration, such as in robotics or IoT (Internet of Things) devices, understanding basic physics might be useful.
Simulation Software:
Developing software for scientific simulations, like climate models, fluid dynamics, or mechanical systems, requires a solid understanding of the underlying physical principles.
Quantum Computing:
If you venture into quantum computing, physics (specifically quantum mechanics) plays a significant role.
Do You Need to Take Physics for Software Engineering?
Basic Requirement: Most software engineering programs may require you to take at least one or two introductory physics courses as part of the general engineering curriculum, but this is often more about giving you a broad scientific foundation rather than focusing directly on software engineering.
Focus on Math: Mathematics is generally more critical for software engineering, especially areas like algorithms, data structures, and cryptography.
Conclusion:
While physics is not a central part of software engineering, having a basic understanding can be beneficial in specific fields within computer science. However, if your primary focus is on software development, programming, and related areas, you won't need an in-depth knowledge of physics, and it may not be a major part of your university coursework.

You've got a nice question!
Physics does play a role in *certain* areas of software engineering, particularly when it comes to specialized fields like computer graphics, game development, simulations, and embedded systems.
Also, understanding physics can help you help you model real-world phenomena, optimize algorithms for performance, and work with hardware more effectively.
However, for most software engineering roles, especially in application development, web development, or systems programming, a deep knowledge of physics is not essential. The mathematical and logical foundations of computer science, such as algorithms, data structures, and software design principles, are usually more critical.
Note, as for whether you need to take a physics course while studying software engineering, that depends on your university's curriculum.

Basic Understanding: Grasping the fundamentals of Physics can arm you with strong logical problem-solving skills and sharpen your analytical thinking.
Specific Areas: If your interests lean towards game development, simulation, graphics, or even certain aspects of AI, Physics can be a key player. For example, in the world of game development, physics engines are used to mimic the physics of the real world.
Formulating Algorithms and Models: Physics concepts like kinematics and dynamics can be handy in crafting algorithms and models for some software applications.
The Need for Physics in University:
General Requirement: A lot of software engineering courses include Physics in their syllabus, especially in the first year. This is to lay a solid foundation in analytical thinking.
Specialization: If you opt to focus on areas where Physics plays a bigger role, having a background in it can be quite advantageous.
In a nutshell, while Physics isn't a must-have for every software engineering path, it can be a great addition to your skill set, particularly in specialized fields. It's definitely a handy tool to have in your toolbox!

Does Physics play a major part? It depends. What kind of software are you developing? If it's to model something in the real world, you may need to know a lot of physics. If you are writing software to check out library books, you will need very little.
Do you need to take physics? It depends. Each school is going to determine the required curriculum for a degree. Go to any college or university website, and you can find exactly what courses are required for a CS degree.

Hello Tamara,
Not directly necessary still it could be a good idea depending on where you would like to focus in your career. You can prioritize other lessons like agile project management as a side development area which is very useful in private sector as a coder. There you can have opportuity to be a product owner or an architect if you feel like in the future. But if you would like to be a mastermind in algorithms additional mathematics and physics helps enlarging your perspective dramatically. So what I would suggest is to question what you want to do in the future as a software engineer.

Hello Tamara!
What a thought-provoking question you've posed!
In my view, delving into Physics can serve as a cornerstone if your ambition is to be a scientist. However, when it comes to computer science, the application of this knowledge isn't as direct. This is primarily because the realm of computers is deeply intertwined with mathematics, algorithms, and logical reasoning.
That being said, it's certainly beneficial to grasp the workings of our world around us (a key focus of Physics), as it broadens your perspective on everyday challenges and situations. This understanding could potentially be harnessed to devise software solutions. Furthermore, if engineering is in your future, a background in Physics can provide you with a competitive edge, particularly if you find yourself working in industries related to Physics.

Hi! If you're asking if you need or should take physics in order to study software engineering in university, the answer is most likely no - unless the university has it as a requirement to complete the degree. I would say the vast majority of software engineers do not need to think about physics on the university level (or high school level for that matter) in their careers.
However, if your question is whether you can combine physics and software engineering as a degree or as a career, you absolutely can! There's a lot of different disciplines of software-engineering and physics where aspects of the other disciplines are necessary or useful.
