John Faulkner, SATRO Volunteer on Paul Dirac, Theoretical Physicist

Ask any physicist today about who they rate as next best British scientist to Newton and the answer might easily be Paul Dirac. Dirac was a theoretical physicist and in 1928 he derived the 'Dirac Equation'. His genius was to construct a single equation that described electron behaviour in all conditions - from the weird world of quantum mechanics to the light speeds of Einstein's special theory of relativity. Put simply the behaviour of every electron that had ever existed in the universe! The power of the equation went further and predicted the existence of a new unsuspected type of matter called antimatter. At the age of 31 Dirac shared the 1933 Nobel Prize for physics. The first anti-matter to be discovered was the anti-electron, or positron, in 1934. Our modern world of electronic wonders would not exist without reference to this one glorious piece of mathematical genius. Knowledge of the positron has enabled the invention of latest non-invasive medical scanners. The Dirac Equation is described in his ground breaking book The Principles of Quantum Mechanics.

Dirac was born in Bristol in 1902 and died in Florida in 1984. As a formidable contributor to quantum theory and one of the world's most respected scientists he held a glittering array of awards and professorships in Britain and the USA. Although happily married he was cripplingly quiet and shy, possibly suffering from autism. This may explain why he is not well known outside the world of physics.

His memorial can be found in a corner of Westminster Abbey - the Dirac Equation carved in stone.

Ever considered a career in Physics?...

Scientists who research in physics are called physicists. Physicists study the world around us and try to discover the laws which explain how and why objects exist and behave as they do, they study everything from tiny atomic particles to the entire Universe as a whole. Physicists look at natural phenomena and use maths to develop theories that help to explain why they occur. Their research acts as the scientific basis for developments in all kinds of technology from medical equipment and electronic devices to space and satellites – the list goes on.

A physicist might be involved in:

  • Climate forecasting
  • Developing new medical instruments and treatments
  • Development of analytical equipment
  • Working in satellite technology and space exploration
  • Investigating new ways to generate power
  • Exploring robotics and artificial intelligence
  • Teaching in schools, colleges or universities
  • Using your knowledge to work in publishing, broadcasting or journalism


To be a physicist you should have:

  • Good scientific and mathematical knowledge
  • An enquiring mind
  • Clear and logical thinking, with good problem solving skills
  • A systematic approach to work, with a high level of accuracy
  • Good communication and presentation skills
  • Report writing skills
  • The ability to work both as part of a team and as an individual
  • Leadership and project management skills


Important subjects related to physics include chemistry, algebra, calculus, statistics and computer science. To get into a physics related job, you will usually need a degree in physics, applied physics or a related science or engineering subject. Some employers may also require a relevant postgraduate qualification such as an MSc, MPhil or PhD. Courses that can be taken as part of a physics degree include thermodynamics, astrophysics, electricity and magnetism, particle physics, nuclear physics, kinematics, quantum physics and much more.

A physicist’s starting salary can be between £21,000 and £25,000 a year. Research physicists who have recently completed a PhD can earn between £25,000 and £35,000. Senior physicists can ear upward of £48,000. (figures are a guideline only)
