 What is physics and why should you take it as a subject?

 

Physics is a dynamic and varied subject, indeed recent events at CERN demonstrate how international physics has become.

 

Have a look at these recent topics under discussion with current A level students

  

In year 12 we look at particle physics into the world of Quarks and leptons and begin to understand what matter really is. We look at and model particles that exist, but that we can never see.

A level physics is constantly under review; in fact a new specification has been designed by AQA. Teaching methods of the course have been developed by staff at John Port to ensure an exciting and fresh start this September. As a prospective physics student next year things will be in full swing.

Investigative and Practical Skills in A2 Physics

 

 What careers could A level physics  lead me towards?

 

Why Physics?

 

Physics offers challenging, exciting, and productive careers. As a career, physics covers many specialised fields -- from acoustics, astronomy, and astrophysics to medical physics, geophysics, and vacuum sciences.

Physics offers a variety of work activities, -lab supervisor, researcher, technician, teacher, manager. Physics opens doors to employment opportunities throughout the world in government, industry, schools, and private organisations.

Physics applications are many and varied

  • ·        Development of sustainable forms of energy production
  • ·        Treating cancer, through radiotherapy, and diagnosing illness through various types of imaging

         all based on physics.

  • ·        Developing computer games
  • ·        Design and manufacture of sports equipment
  • ·        Understanding and predicting earthquakes

 

The list is almost endless

 

Good luck on making an informed choice.

I hope physics is one of them!
