Why study physics ?
|
This is the first question that any BS Physics student should be able to answer as soon as he gets into the level between heaven and hell.
Well, people, especially those who are totally inclined to do easy jobs, have one point of convergence. They tend to be magnetized to the higher level of thinking. Each of them seek their own philosophies. Fortunately or unfortunately, these kind of people free fall to the field of physics.
Until now, no one, even the physicists themselves, cannot explain this very elaborate and symmetric field. No one can understand the behavior of this kind of field. In fact, the physics field cannot be grouped under the electric field, the magnetic field, the quantum field, or even in the track and field. ( The latter is the field wherein physicists are very unhesitant to tackle.) Perhaps, the field of physics is the ultimate answer to the very bothering question presently discussed by the brilliant members of the field-- the physicists--, the question on Unified Fields.
I can, as of now, say that the physics field is very non-intimidating. It is probably the Unified Field itself.
The answer to the very basic question "Why study physics? " is known to every BS Physics student. Why not ask them about it and they will discuss to you the pros and cons of studying physics.
Physicists study the principles of energy and their action on matter. Their knowledge of physics enable them to help analyze and propose solutions to the environmental problems such as food shortage, pollution, and harmful effects of radiation. It is through their initial efforts that we enjoy the convenience of modern home appliances, ease and safety of travel, the speed of communication, bountiful harvests through mechanized farming, use of laser and ultrasonics in medical diagnosis and therapy, and prosperity in commerce and industry. Thus, PHYSICISTS OPEN UP SCIENCE AND TECHNOLOGY.

Historical facts on physics
|
1. Long time ago, people believed that the Earth is the center of the Universe. One of the advocates of this idea is Ptolemy.
2. During the late 19th century, the physicists thought that they have the answer to all physical phenomena for they had established the connection between electricity and magnetism through the discovery of electromagnetic wave by Hertz. Unfortunately, the discovery of EM wave lead also to the discovery of photoelectric effect which cannot be explained by any existing physics during that time.
3. In the mid-16th century, Copernicus published De Revolutionibus, suggesting that the earth and the planets orbited around the sun. This is contradictory to the early belief that the earth is the center of the universe, with planets and the stars circling around it.
