I can get new and useful knowledge from the sciences books, so I am interested in sciences in an academic field. Because sciences are divided into many classes, and I can't describe a full classification of sciences with my in being knowledge, therefore I will only describe certain parts of the total classification. Science is classified into pure science and natural science. Pure sciences include mathematics, physics and chemistry, natural sciences include earth sciences and biology, and each science also marks off some relevant fields of study.

Firstly, I describe pure sciences. The science of mathematics consists of five categories; these are general mathematics systems, algebra and number theory, geometry, probabilities and mathematical statistics. Geometry may be defined as the branch of mathematics which studies the mathematics of the properties, measurement and relationships of points, lines, angles, surfaces and solids. Probabilities may be defined as the branch of mathematics which studies a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrence.

Physics consists of five categories. These are mechanics, aerodynamics, optics, thermodynamics and electricity and electronics. Aerodynamics may be defined as a branch of physics which studies the dynamics of bodies moving relative to gases, the interaction of moving object with the atmosphere. Thermodynamics may be defined as the branch of physics which studies the relationships between heat and other forms of energy. And the three kinds of mechanics are solid mechanics, fluid mechanics and gas mechanics. The four kinds of electricity and electronics are electromagnetism, electrostatics, electrodynamics and thermoelectricity. Chemistry may be defined as the science of the composition, structure, properties and reactions of matter, especially those of atomic and molecular systems. It consists of four categories. These are theoretical...
