Physicist Overview

Do you want to research to develop a membrane that will produce pure oxygen which could be used eventually to generate enough electricity to drive cars with much less pollution and cost? Or may be develop chemical sensors that can detect chemicals in the air or water, which will then serve as a warning system for poisonous or flammable gases. Then you got to be a Physicist… 

 

A branch of the physical sciences, physics is the study of energy and the behaviour of single atoms and their component pieces. Physicists consider themselves the most fundamental of scientists, for they are the ones who examine the basic laws of nature. They study what happens when atoms and subatomic particles break down and assemble how they react to collisions with each other. 

 

Physicists use mathematics to understand, explain and predict their theories and equations. They often apply their theories to other fields like chemistry, biology, geophysics, engineering, communication, transportation, electronics and health. 

 

Physicists work by determining the basic laws governing phenomena such as gravity, electromagnetism and nuclear interactions that lead to discoveries and innovations that advance nuclear energy, electronics, communications aerospace technology and medical instrumentation. 

 

Physicists also study the properties and interactions of matter and energy in all their forms. Their interest may range from understanding fundamental physics to developing new technologies in applied physics. They test their observations against the present theories of physics and new hypotheses. 

 

Classical physics refers to the science prevalent prior to the twentieth century. It begins right from the inventions and discoveries of scientists like Galileo and Newton. The studies are broadly classified under five headings, namely Mechanics, Heat and Thermodynamics, Sound, Electricity and Magnetism and Light.

 

Generally, although a physicist should have a broad background of all the five areas of physics, he/she specialises only in one of them. Geophysicists combine the knowledge of geology and physics.

 

Geophysics is used in the study of meteorology, hydrology, oceanography, seismology, radioactivity and magnetism. 

 

Biophysicists study living organisms and life processes 

 

Medical physicists play a vital role in the designing and use of electronic equipments for use in the medical sector 

 

Astrophysicists design equipment for astronomical study and also interpret the research findings of astronomers, particularly in thermonuclear research related to space sciences.

 

A physicist can be either an experimentalist or a theoretician. Almost all have doctorates, which are essential for college and university teaching and research, upper level research positions in government and industry, and higher administrative positions.

 

Those with bachelor's degrees may work in applied research and development as research assistants or in design, administration or engineering. 

 

Specialised areas for physicists are mechanics, atomic and molecular physics, heat, optics, acoustics, electricity and magnetism, electronics, nuclear physics, physics of fluids, solid state physics, or classical theoretical physics. Emerging areas of study for physicists are cryogenics, crystallography, and plasma physics. 

 

Research in physical sciences is broad ranging and includes, for example, observations on how weather systems develop, laser physics and the production of anti-tumour drugs from marine organisms.
