Physics, pesiká or pisiká (from the Greek, φύσις (phúsis), "nature" and φυσικός (phusikós), "natural"), the most fundamental natural science, deals with the fundamental principles of the Universe. Physics deals with the elements that make up the natural world (e.g. matter, energy, space, and time) and their interactions, as well as the analysis of systems that are clearly expressed in the language of these principles.


Pesika began as a Philosophy-natural during the Archaic period of Greece (650 BCE-480 BCE). Philosophers such as Thales sought methodological explanations of natural phenomena. They provide ideas based on reason and observation, and many of their hypotheses have been proven experimentally; such as atomism, which has been proven to be correct nearly 2000 years since it was first proposed by Leucippus and Democritus. Pesika was a science in early modern Europe by using experimental and quantitative methods to discover what are now considered laws of physics.

Classical Pesika

Classical physics includes traditional branches such as mechanics, acoustics, optics, thermodynamics, and electromagnetism. Classical mechanics deals with objects that are repulsed and repulsed by forces, and divides them into statics, kinematics, and dynamics; Mechanics is further divided into solid mechanics and fluid mechanics. Fluid mechanics includes the branches of hydrostatics, hydrodynamics, aerodynamics, and pneumatics.

Modern and Pesika

Modern physics presents a different concept of space, time, and matter presented in classical physics. The two theories that dominate modern physics are the Quantum theory and the special theory of relativity. Quantum mechanics is all about modern physics.
