Related subjects
Most relevant
- Physics - Physicists study the fundamental behaviour of matter, energy, forces, and the universe itself – physics is the core of everything they do. They design experiments, develop theories, and apply principles from mechanics, electromagnetism, quantum physics, and thermodynamics to solve problems and make new discoveries.
- Mathematics - Physicists use advanced mathematics every day to build models, analyse data, and express the laws of nature in precise equations. From calculus and differential equations to statistics and linear algebra, maths is the language physicists use to describe and predict how the universe works.
- Computer Science - Physicists build computer simulations and use programming to model complex systems, from particle interactions to climate patterns. Writing code to process large datasets, run numerical calculations, and visualise results is a routine part of modern physics research.
Also relevant
- Chemistry - Physicists working in areas like materials science or energy engineering need to understand atomic structure, bonding, and how substances interact at a molecular level. Chemistry and physics overlap significantly when investigating the properties of new materials such as superconductors or alternative fuels.
- Engineering - Physicists often apply their knowledge to engineering challenges, such as designing satellite instruments, developing medical scanners, or building experimental equipment. Understanding engineering principles helps them turn theoretical ideas into practical devices and systems.
- Biology - Physicists working in medical physics or biophysics need to understand how the human body works. For example, building more sensitive medical scanners requires knowledge of how radiation interacts with living tissue.
- Electronics - Physicists frequently design and build experimental apparatus that relies on electronic sensors, detectors, and circuits. Understanding how electronic components work is important when setting up instruments to measure physical phenomena with precision.
- Environmental Science - Physicists can apply their skills to understanding atmospheric and oceanic systems, interpreting satellite data, and predicting environmental changes. Knowledge of environmental science provides useful context for physicists working on climate research or pollution reduction technologies.
How to become
You can get into this job through:
- a university course
- an apprenticeship
- a graduate trainee scheme
You can do a degree to start your career in physics. The course you choose will depend on your area of interest.
Course examples include:
- physics
- astrophysics
- mathematics
- medical physics
- computer science

If you do not have the required entry qualifications to do a physics degree, you may be able to do a 1-year physics foundation course before moving onto a degree.
Some physics degrees combine an undergraduate course with a postgraduate master's qualification, like an MPhys or MSci. On these, you'll do more independent research, and courses can lead to further study for a PhD.
Entry requirements
You'll usually need:
- 2 or 3 A levels, or equivalent, including maths and physics
- a degree in a relevant subject for postgraduate study
More Information
You could apply for a Degree Apprenticeship work-based training scheme. There are a lot of options available to develop your skills in physics.
Examples include:
- Robotics Engineer Level 6
- Nuclear Scientist Level 6
- Space Systems Engineer Level 6
- Scientist Level 6
- Research Scientist Level 7
These apprenticeships take between 3 and 5 years to complete.
Entry requirements
You'll usually need:
- 4 or 5 GCSEs at grades 9 to 4 (A* to C) and A levels, or equivalent, for a degree apprenticeship
More Information
You may be able to apply for a place on a graduate training scheme with a commercial company, government department or university, after completing your degree or postgraduate qualification.
