Physics is the fundamental science and the important key to understand the universe as well as nature phenomena. The fact that the progression of understanding physics behind the nature phenomena such as the motion of electron, waves, and other things significantly improve the quality of our everyday lives and directly help the mankind to build their modern civilization. Physics has opened the way up for other areas of science such as chemistry, biology, and medicine to extend their research. For instance, quantum mechanics formulation was proposed by Schrödinger, Dirac, and Heisenberg is widely used in chemistry to predict the properties of molecule such as molecule configuration, binding energy, etc. Also, the discovery of fiber optics and Magnetic Resonant Imaging has made a great impact to the medicine. The discoveries help the medic to find the finest way to cure the disease as well as surgery.
The most characteristic of science is its application, the fact that as a consequence of science one has a power to do things. The whole industrial revolution would almost have been impossible without the development of science. And physics has made a great contribution to the human technology as well as the industrial revolution. In other hand, our today’s technology is nothing without physics.
For instance, one of the physics branch i.e. condensed matter physics which is I am interested in, is the source of such technological innovations. Condensed matter physics has the greatest impact on our daily lives through the technological developments to which it gives rise. Such familiar devices as transistor, which has led to the miniaturization of a variety of electronic appliances; the semiconductor chip, which has made possible all the myriad aspects of the computer; magnetic tapes used in recording of all kinds; plastics for everything from kitchen utensils to automobile bodies; catalytic converters to reduce automobile emissions; composite materials used in fan jets and modern tennis or badminton rackets; and NMR tomography are a few practical consequences of research in condensed matter physics, and in physics generally.
These examples illustrate the intimate connection between fundamental science, physics, and the development of basic new technology for human prosperity. Indeed, the full extent to which the consequences of research in physics play a role in the quality of our everyday lives.
The fact that physics provides such an enormous number of degrees of freedom that the intellectual challenges that it presents are found. A high degree of creativity is required to find conceptually, mathematically, and experimentally tractable ways of extracting the essential things/features. Physics is intellectually stimulating also because of the discoveries of fundamentally new phenomena, the development of new concepts, and the opening up of new subfields which can be correlated with other areas of science such as chemistry, biology, and even social science.
