The application of science in modern world has produced many proven technology that can make human life easier, more comfortable, healthier, and safer. Science is a great gift for human being of all over time. With science, human managed to solve problems experienced in his/her life so as it able to improve the quality of his/her life. Beside, science is also one way to achieve objective truth. Physics is a science that deals with the interaction between physical phenomena and human as observer. It is a tool to explain the nature of physical world of the universe. Physics is very interesting because it can explain complex phenomena from microscopic world to the macroscopic world in simple, elegant and beautiful mathematical language.
Driven by curiosity, mankind is always zeal to know what really happened in physical world. Curiosity rises from the interaction between human sensory and environment or physical world where human are. Physics is always initiated by such interaction. From the interactions, various kind of information about physical units can be obtained. The interaction is not always a direct interaction between human sensory and physical phenomena, scientist often use instruments to help them to get information about the physical world which beyond the range of human sensory. Astrophysicist uses the telescope to obtain information about macroscopic world such as stars, planets, nebulas, etc. Solid State physicist uses electron microscope to obtain information and explore the microscopic world such as atom and electrons. From such interaction, physicist derives theories which provide systematic explanation of the interaction between physical phenomena. Theory brings physicist to develop some methods and certain process in order to confirm the truth behind phenomena that occurs. The confirmation of the truth between theory and experiments yields what we called knowledge.
Physics is divided into two different methods of study; experimental and theoretical. Experimental physics deal with observation of the physical world in order to get data from the physical world, whereas theoretical physics deals with explaining data and predicting the nature of the physical world. These two methods of study are complements one to another, they provide mutual symbiotic with one goal that is to understand how nature works.
Science is always placed parallel to technology; progress in science is almost always followed by the progress in applied technology. History has proven that research in science base always plays an important role in development of advanced technology. Recent development in electronics and more advanced in nanoelectronics devices are initiated by basic research in physics. Research in basic modern physics which is pioneered by giant physicist such as Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Wolfgang Pauli, Erwin Schrödinger many years ago is undoubtedly bring massive influence in today’s modern technology. The fact that research done by late Nobel Prize in physics winner Professor Konstantin Novoselov and Professor Andrea Geim for the ground breaking research in graphene will bring another advanced development in carbon based electronics technology to replace recent silicon-based technology is undeniably will come into reality.
The development of Physics is closely related to education. Physics education plays an important role in future development of technology and will determine the direction of human life on earth in the future. Good education in physics for young generation will determine the sustainability of physics development in the future. The future of physics is depend on how many young people get involved and interested in physics subject. Thus, it is important have good and expert teacher in physics who can motivate more young people to get involved and later get deep into research in physics.
