Abstract: physics as one of the most basic natural sciences, in the process of generating the formation and development, contains a wealth of human culture. In order to fully exploit the natural sciences humanistic ideas, to strengthen the link between science and culture and humanistic culture, the three aspects of the article from the materialist dialectics, aesthetic, scientific ethics analysis of the physics of human culture.
Keywords: Physics; human culture

Physics is one of the most basic natural sciences, it is to explore the disciplines of the basic structure of matter and material law of motion, so people tend to believe that physics is just boring theoretical formula, while ignoring the human factors contained in the physics such as humanities philosophy, aesthetics, ethics. In fact, physics in the production, the formation, the process of development, it is not for physics research in physics, but in order to contribute to the development of human, social and individual study of physics, all of which are related to the people the relationship between people, the relationship between man and nature, these relationships contains a wealth of human culture.
CS Wu pointed out: In order to avoid the crisis in the sustainable development of society, an urgent problem is to eliminate the gap between the two cultures, science and culture and human culture in the modern culture, and strengthen these two aspects, a famous physicist linked. There is no place more suitable than the university. Only when the two cultural barriers to be bridged in the university garden, we can given the world a coherent and convincing. So we need to discuss the humanistic ideas in science and culture.
The following analysis of physics from a cultural perspective of humanistic ideas, mainly the following aspects:

1 Physics of materialist dialectics thought

Physics in ancient times was called natural philosophy, physics as a sophisticated discipline study from the beginning of 1687 Newton published Philosophiae Naturalis Principia Mathematica ". With the development of the discipline and constantly improve, physics was split off from philosophy to form a separate discipline, but the philosophy behind the physical culture will not be separated.
1.1 Practice is the sole criterion for testing truth
Physics is an experimental science, physics experiments both to establish a physical theory is based on the method of testing the truth of the physical theory. Professor Yang Chen said, "physics based on experiment-based discipline, a lot of theories in physics demonstration by experimental test results, reflects the the materialist dialectics epistemological point of view - practice is the sole criterion for testing truth.
1.2 substances are commonly associated
The history of development of the physical, many places reflects the substance is commonly associated view. For example, people had electricity and magnetism isolated, physicist Oersted accept the unified forces of nature philosophy. Firmly believe that there is a potential link between electricity and magnetism, after years of study, and finally discovered the magnetic effect of current, and thus creating a new era of electromagnetism. Electric and magnetic contact, which embodies the the materialist dialectics characteristics - the substance is commonly associated.
1.3 things in the development of the law of "negation of negation"
Understanding of the physical phenomenon and its essence is to continue to develop and improve the a theory of the process of establishing the concept of "experiments (facts) - theoretical assumptions - experimental (new facts) - modified theory , follow the "negation of negation" laws of dialectical materialism. For example, in the history of the development of the entire optical light of the understanding of the nature of the problem, the first Newton's corpuscular theory; Huygens elastic wave theory; followed by Maxwell electromagnetic wave action that; said to the 20th century, Einstein's light quantum. Eventually people realize that light has a wave-particle duality, the understanding of human nature to light is to follow the "negation of negation" understanding of the law of reflection.
1.4 the principal contradiction and the secondary contradictions dialectical relationship
Physics in order to facilitate the study of problems, often seize the main features of the object, ignoring the secondary features of the object, and smoke come up with some ideal model. Such as "particle" ideal model retains the actual mass of the object and the location, while ignoring the size and shape of the object itself, reflecting the dialectical materialism in the dialectical relationship between the principal contradiction and the secondary contradictions.
1.5 relativity of motion and time and space relative
A theory of modern physics - Einstein's theory of relativity involved in a lot of philosophical questions. The most prominent is the relative motion and relative concept of time and space. The theory of relativity: the essence of the principle of relativity is the relativity of motion to the fact that without the existence of absolute motion. Relativistic denial of the existence of absolute motion, to deny the concept of absolute space and time. Constant speed of light combination of time and space as a whole, by the Lorentz transformation to establish the temporal and spatial relationship between the various inertial system.
Visible, both physical and cultural knowledge, physical culture, the process of development contains a wealth of philosophical thinking, have a significant impact on the human view of nature and philosophy. The 2 physics aesthetic culture

2.1 physical theory of aesthetic features
2.1.1 simple and profound beauty
Simple kind of beauty in the eyes of an artist. Complex natural phenomena, physics strive to use simple equations or law to summarize the laws of nature, but reflect the inherent law is indeed very deep. Energy transformation and conservation reflects the conversion of various forms of energy, Newton's three laws of general mechanical law of motion of the low speed conditions, the Maxwell equations unified complex electromagnetic phenomena which, Einstein's theory of relativity, the basic principle is simple and concise, but the connotation is really rich and deep.
2.1.2 Symmetry Conservation
Symmetry is widely present in nature is also very willing to accept an aesthetic form of physics in the representation of nature is evident at the beauty of symmetry: attraction and repulsion, "electrophysiological magnetic" and "magnetic raw power , particles and anti-particles, matter and antimatter, hole or single-slit diffraction pattern symmetry, infinitely long straight wire, the magnetic field around the axis of symmetry. Invariance of the laws of physics to some kind of gauge transformation, conservation is a symmetric form throughout the entire physics, the many conservation law in physics: conservation of momentum, conservation of mechanical energy, and so on. In fact, the symmetry has become a method of the physical theory of contemporary physicists.
2.1.3 unified and harmonious beauty
Physical theory of harmony and unity of the United States is actually the United States and the theoretical form of harmony and unity in nature. Such as electromagnetic theory of Maxwell unified electricity, magnetism, optics, quantum mechanics volatility and particle unified unify Einstein's theory of relativity of time, space, matter and motion, all inclusive in classical physics within the framework of his theory to create a higher degree of broader theory of harmony and unity.
2.2 physicist and aesthetic ideas
The world-famous physicist Dirac: an equation to beauty than experiment more important. French scientists Poincare once said: "Scientists study of nature, from which he can have fun, he has been able to have fun, because of her beauty. Famous physicist Chen Ning Yang once said: "the principles of physics has its structure that its beauty with wonderful physics workers feel the beauty of this structure with wonderful, different, because we have different feelings, so every worker will develop his own unique research direction to form his own style. "
Many well-known physicist singular ability to have a sense of beauty, aesthetic ideology founded with the evaluation of theoretical physics plays a major inspiration and guiding role in many physicists. Trace the source of human science, science and the United States has always been as a humanistic ideals and the pursuit of one of the direct driving force scientists to careers in science, painstaking research.

The 3 physics scientific moral and spiritual

3.1 of the unknown with curiosity and the spirit of exploration
Curiosity is an emotion, a human spirit, and most important scientific spirit. The real driving force of scientific progress is the desire of many physicists to understand the unknown. Newton saw the fall of an apple, go to think why Apple will fall from a tree, to think of gravity; Archimedes inspiration from the tub bathing, found the water to invade the intrinsic link between the partial volume rose with his body, whether the identification of a gold crown adulteration is found, resulting in Archimedes' principle, found buoyancy. This unknown curiosity and the spirit of exploration, a very important role in the development of physics and human civilization.
3.2 the scientific spirit of seeking truth from facts and innovative
Cognitive basis of seeking truth from facts, and innovation is the core of the scientific spirit. The revolution of the 20th century physics tells us: scientists to set up a new theory of the development of science on the road, must have the courage to existing old theory, old ideas to challenge the courage. For example: Galileo is the movement of objects cause "suspected Aristotle force before the establishment of the right of force and motion. That Newton's laws of motion generation later. Famous physicist Chen Ning Yang and Tsung-Dao Lee, precisely because of the keen awareness to the scope of application of the law of conservation of parity has never been doubted, boldly put forward the thesis of weak interaction parity violation, only to theoretical physics of a breakthrough.
