All human life is surrounded a set of the various phenomena. Scientists-physicists are engaged in studying these phenomena; mathematical formulas and achievements of predecessors act as their tools.
Natural phenomena
Studying the nature helps to belong more reasonably to the available resources, to open new power sources. So, geothermal sources warm almost all Greenland. The word "physics" goes back to the Greek root "fizis" that is meant by "nature". Thus, physics - science about the nature and the natural phenomena.
Forward, in the future!
Often physics literally "advances time", opening laws which find application only decades (and even centuries) later. Nikola Tesla opened laws of electromagnetism which find application today. Pierre and Marie Curie opened radium practically without support, in inconceivable conditions for the modern scientist. Their opening helped to save tens of thousands of lives. Now physics of the whole world is concentrated on Universe questions (macrocosmos) and the smallest particles of substance (nanotechnologies, a microcosm).
Understanding of the world
The most important engine of mankind is the inquisitiveness. That is why experiments in the Big Hadron Collider have such high importance and are sponsored by the union from 60 states. There is a real opportunity to reveal secrets of mankind.
Physics - fundamental science. It means that any opening of physics can be used in other spheres of science and technology. Small opening in one industry can influence strikingly all "next" industry entirely. In physics practice of a research by groups of scientists of the different countries is popular, the policy of the help and cooperation is accepted.
The mystery of the universe, matter disturbed the great physicist Albert Einstein. He offered the theory of relativity explaining that fields of gravitation bend space and time. The well-known formula E = m * C * C, connecting energy with weight became apogee of the theory.
The union with mathematics
The physics leans on the latest mathematical tools. Often mathematicians open abstract formulas, bringing the new equations out of existing, applying higher levels of abstraction and laws of logic, doing courageous hypotheses. Physicists monitor development of mathematics, and sometimes discoveries of abstract science help to explain the natural phenomena unknown until then. Happens and vice versa - physical opening push mathematicians on creation of hypotheses and the new logical device. Communication of physics and mathematics - the authority of physics supports with one of the major scientific disciplines.
