[edit] Activities in physics

There are many types of activities in physics:

  • Experimental physics

To get the data that physics relies on, experiments are made sometimes.

  • Observational physics

Sometimes experiments are not possible, but data is still found by observation.

  • Instrumental physics

Often special kinds of devices, machines and instruments have to been designed and built to make the measurements and observations in physics.

  • Theoretical physics

To explain the data, theories are produced.

  • Mathematical physics

Often equations and mathematical analyses are important to make models based on these theories, or to develop methods for analyzing and processing the data. This is called mathematical physics:

  • Computational physics

Numerical models are produced based on these theories, and predictions are made. Also, the data is analyzed. Both of these rely on extensive computations, usually done on computers:

  • Applied physics

Many people work in using the methods, data and theories of physics to make things or do tasks. This is called applied physics. Applied physics sometimes overlaps with engineering.

[edit] Fields of physics

Physics is roughly broken into two parts; classical physics and modern physics. Classical physics is the physics that does not use quantum mechanics or relativity. Modern physics is the physics that uses quantum mechanics and relativity. There is some overlap between classical physics and modern physics. Modern physics was mainly created after the year 1900.

[edit] Fundamental forces

There are four known forces in physics:

  1. Gravitational
  2. Electromagnetic
  3. Weak
  4. Strong

In unified field theory, physicists attempt to understand how these four forces are all different aspects of a single force.

[edit] Theories of physics

A theory is an explanation created to describe the measurements and observations. There are many theories in physics. Some theories belong mainly to classical physics and some belong mainly to modern physics.
