Mathematics is a subject that studies concepts such as quantity, structure, change and spatial model. By using abstract and logical reasoning, the shape and motion of objects are counted, calculated, measured and observed. Mathematicians have extended these concepts in order to express new conjectures with formulas and establish strictly deduced truths from properly selected axioms and definitions.
Mathematical attribute is the measurable attribute of anything, that is, mathematical attribute is the most basic attribute of things. The existence of measurable attributes has nothing to do with parameters, and the result depends on the selection of parameters. For example, time, whether measured in years, months, days or hours, minutes and seconds; Space, whether measured in meters, microns, inches or light years, always has their measurable properties, but the accuracy of the results is related to these reference coefficients.
Physical pinyin: wù lǐ, the full name of physics. Physics is a natural science that studies the most basic structure, the most common interaction, the most common law of motion and the experimental means and thinking methods used in the material world. In modern times, physics has become one of the most basic disciplines in natural science. The laws of physics verified by a large number of rigorous experiments are called laws of physics. However, like many other natural science theories, these laws cannot be proved, and their correctness can only be tested through repeated experiments.
The word "physics" comes from the Greek word φ υ σ ι κ, which means nature. In ancient times, Europeans called physics "natural philosophy". In the broadest sense, it is the study of natural phenomena and laws. The word "physics" in Chinese and Japanese originated from Fang Yizhi's encyclopedia "Little Knowledge of Physics" in the late Ming and early Qing Dynasties.
In the field of physics, study the basic elements of the universe: matter, energy, space, time and their interaction; By analyzing the basic laws and rules, we can fully understand this system. Physics is composed of the study of natural philosophy which is very similar to the classical times. It was not until19th century that physics was separated from philosophy and became an empirical science.
Physics is closely related to many other natural sciences, such as mathematics, chemistry, biology, astronomy and geology. Especially mathematics, chemistry and biology. Chemistry has a far-reaching relationship with some physical fields, such as quantum mechanics, thermodynamics and electromagnetism, and mathematics is the basic tool of physics.
