BRANCHES OF PHYSICS

PHYSICS EXAMINES THE BEHAVIOUR OF MATTER AND ENERGY,WHICH,TOGETHER WITH EMPTY SPACE,MAKE UP THE ENTIRE UNIVERSE.FOR THIS REASON, THE THEORIES AND METHODS OF PHYSICS CAN BE USED IN ANY AREA OF SCIENTIFIC STUDY. BIOPHYSICS - A BIOPHYSICIST STUDIES THE PHYSICAL PROCESSES AND CHANGES THAT OCCUR IN LIVING THINGS AND THE WAY THEY RESPOND STIMULI SUCH HEART AND LIGHT.ELECTRON MICROSCOPES ALLOW BIOPHYSICISTS TO SEE OBJECTS TOO TINY FOR EVEN OPTICAL TELESCOPES TO DETECT. MEDICAL PHYSICS - USING THE METHODS OF PHYSICS TO HELP DIAGNOSE AND TREAT ILLNESS IS CALLED MEDICAL PHYSICS.ONE OF THE BEST KNOWN TOOLS OF THE MEDICAL PHYSICIST IS THE CAT SCANNER,WHICH USES X-RAYS TO GIVE 3-D IMAGES OF BODY ORGANS AND TISSUES. PARTICLE PHYSICS - MATTER IS MADE UP OF MORE THAN 200 PARTICLE,INCLUDING ELECTRONS,PROTONS AND QUARKS.MACHINES CALLED BUBBLE CHAMBERS AND PARTICLE ACCELERATORS ALLOW PHYSICISTS TO STUDY THESE TINY PARTICLES AND DISCOVER NEW ONES. GEOPHYSICS - A GEOPHYSICIST STUDIES THE PHYSICAL PROCESS THAT TAKE PLACE ON AND WITHIN THE EARTH,INCLUDING ROCK FORMATION,THE EARTHS MAGNETISM,AND VOLCANOES.DEVICES CALLED SEISMOGRAPH HELP GEOPHYSICISTS TO RECORD AND EARTHQUAKES. ASTROPHYSICS - THE STUDY OF THE PLANETS,STARS AND GALAXIES THAT MAKE UP THE UNIVERSE IS CALLED ASTROPHYSICS.IT MAKES USE OF DATA COLLECTED BY TELESCOPE.COSMOLOGY IS THE PART OF ASTROPHYSICS THAT ATTEMPTS TO EXPLAIN HOW THE UNIVERSE BEGAN.
