Danish physicist Bohr once said: Physics does not tell us what the world is, but what we can talk about it. Physics, as the leading discipline of natural science, studies the most basic motion forms and laws of all substances from the universe to elementary particles, so it has become the research basis of other natural science disciplines. Physics is one of the most important basic disciplines, and the major of physics is the most advantageous and easy for China students to get scholarships. Every year, a large number of China students go to the United States to study physics. So, what is the major of physics? 1. What major do students with good physics study? 1, atomic physics. The microscopic process of high temperature plasma, the structure, spectrum and collision process of atoms and molecular clusters, the physics of highly charged ions, the interaction between laser and matter, the physical design and preparation of materials, and molecular nano-physics are studied. 2. Biophysics. Biophysics is a new interdisciplinary subject gradually formed after the mid-20th century, which is the product of the combination of physics and biology. It is one of the fastest developing departments of contemporary natural science. Biophysics is a science that uses the theories, techniques and methods of physics to study the physical properties of biological substances, the physical and physicochemical laws of life processes and the mechanism of physical factors on biological systems. The content of biophysics research is very extensive, which is generally divided into quantum biophysics, molecular biophysics, cell biophysics and complex system biophysics. The problems involved include almost all the basic problems of biology. In recent years, the development trend of biophysics focuses on the intersection with broader disciplines, such as mathematics and informatics. The research directions of this subject are: neurobiophysics, brain functional imaging and its application, neuroinformatics and bioinformatics, theoretical biophysics and computational neuroscience. This direction is a new interdisciplinary subject in recent two years. Applicants are not only physics majors, but also biology majors, so the competition is fierce and the annual Offer is very small. 3. condensed matter physics. Condensed matter physics is a science that studies the structure of condensed matter and the interaction and motion law between constituent particles (such as atoms, molecules, ions and electrons), and expounds its properties and uses. It is a branch of physics, with various categories, rich content, rapid development and wide application, and has become an extremely active research field in physics today. This major direction is one of the major directions that China students mainly apply for, and it is relatively easy to get scholarships. Peking University and Nanjing University are very strong in this respect. 4. cosmology The branch of science that studies the universe as a whole is collectively called cosmology. For cosmologists, questions about the structure and history of the universe. It's actually about gravity. Because gravity can work at a long distance, it is the force that has the greatest influence on the overall nature of the universe. Einstein's "theory of relativity" is still the best theory about gravity we have, so most cosmologists are trying to explore how to apply Einstein's theory to the whole universe. 5. High energy physics. High-energy physics, also known as particle physics or elementary particle physics, is a branch of physics, which studies the structural properties of substances in the microscopic world deeper than the nucleus, the phenomena of mutual transformation of these substances at high energy, and the reasons and laws of these phenomena. It is a basic subject and one of the frontiers of the development of contemporary physics. Particle physics is based on experiment, and also on the close combination of experiment and theory. Peking University has a strong research strength in this field, and he has a strong strength in particle physics experiments. 6. Computational physics. Computational physics is a new frontier discipline among computer science, computational mathematics and physics, and it is recognized as the third pillar of physics alongside theoretical physics and experimental physics. 7. Astrophysics and astronomy. Astrophysics is to study the origin, evolution and death of celestial bodies in the universe by using the theories and methods of physics, mathematics and chemistry. It mainly includes the shape, internal structure, physical state, chemical composition and relationship of celestial bodies. Generally, it is divided into two aspects: measurement astrophysics: methods and means of celestial observation, processing and analysis of observation results, etc. Theoretical astrophysics: physical interpretation of observation results, study of physical, chemical and motion characteristics of celestial bodies. 8. Optical physics. Including quantum optics, nonlinear optics, high-resolution spectroscopy, etc. Breakthroughs in these fields have become an important support for the laser and optical fiber communication industries. China University of Science and Technology is very strong in this respect, and this direction is also one of the main directions for Chinese physics applicants. 9. Applied physics. Applied physics majors highlight the application of physics in the fields of optical communication and information science, physical electronics and optoelectronics, with emphasis on nano-materials and devices, optoelectronic devices, microelectronics, physical electronics and electronic technology. At present, this direction has been merged into EE in many universities, some have become a department alone, and some applied physics majors have been merged into the College of Engineering and Applied Science. This research direction plays a very important role in developing a new generation of microelectronic materials and devices and quantum devices. 2. Recommended institutions for studying abroad in physics 1 and MIT. The facilities of MIT are all Daniel, each with its own nature and science. As for the articles of PRL (physical review letters), they are just ordinary achievements. The research work of physics department of MIT includes four research fields: astrophysics; Atoms, condensed matter and plasma physics; Experimental nuclear physics and particle physics; Theoretical nuclear physics and particle physics. 2. University of Chicago. The world's first 1 nuclear reactor was born on the football field of the University of Chicago. The University of Chicago is also the school with the largest number of foreign Nobel Prize winners. His research fields include astrophysics and cosmology, condensed matter physics, biophysics, atomic physics, general relativity, nuclear physics and particle physics. The study of condensed matter physics includes thin films, quantum transport and so on. The stronger direction is particle physics. The strength of condensed matter is also good. 3. Cornell University. One of the Ivy League schools. The research fields of physics department include particle physics, astrophysics and general relativity, accelerator physics, condensed matter physics and biophysics. Condensed matter physics is a large group, and its research directions include: non-equilibrium system principle, complex fluids and polymers, critical phenomena and phase transitions, nanostructures, low-temperature physics, quantum fluctuations and entanglement, ultracold atoms, etc. Professor David and Professor robert anderson were awarded the 1996 Nobel Prize in Physics. 4. University of Wisconsin-Madison. This school attaches great importance to hardware conditions. There are four groups in AM0 direction, which study nonlinear optics and atomic physics, atomic collision, quantum computing and ultrafast science, ultracold atoms and laser cooling respectively. Condensed matter is a large group, and his research interests include nanomaterials, nanodevices, nanoelectronics, nanomechanics, NEMS, MEMS, superconductivity, quantum computing, femtosecond science, biomaterials, polymers, magnetic films and so on. Iii. Application conditions for foreign physics majors 1. Foreign institutions prefer applicants born in some top universities in China. Because most of them have performed very well after going to universities abroad, foreign schools will pay more attention to recruiting these students. Of course, the relevance of the applicant's professional background is also closely related to the difficulty of application. When applying for graduate students, the first thing to consider is whether your research direction matches your application direction, and the second is whether it is related to Professor Tao Ci's research direction. Therefore, when choosing a school and a professor of magnetism, the most important thing is the degree of professional matching. 2. The applicant's hardware level GPA, GT scores, scholarships and other academic conditions have become a more intuitive reflection. Generally speaking, professional GPA is more influential than comprehensive GPA, and undergraduate GPA is more influential than graduate GPA. Graduate schools of the top 50 schools usually require: GPA at least 3.5 (B+); GREV+Q & gt； 325, the physics department of some schools requires PhysicalSub scores, and GREsub schools pay more attention to percentages than just scores; IBT & gt； 100。 Follow-up schools usually require: GPA & gt3.0(B), but the average GPA of students admitted is generally around 3.3(B+); GREV+Q & gt； More than 3 15; IBT & gt； 90, but judging from the competition in recent years, if IBT wants not to be easily squeezed out in the fierce competition, it must try to get above 90, and the hope of getting a teaching assistant scholarship is relatively great. After all, there are few opportunities for international students to get grants. 3. The applicant's thesis, research experience and work experience. Scientific research experience can be said to be a prerequisite for applying for a doctorate, and work/internship experience is also an important experience for foreign schools to enrich their experience and help applicants to clarify their development direction. Professional thesis is the concrete embodiment of research experience and professional research level, which is more convincing than the brief description in resume. What do students who are good at physics learn? I think all your friends know! Foreign physics majors provide excellent education for foreign students, so foreign students must understand the specific requirements and institutions when applying for physics majors. I wish you all an early realization of your dream of studying abroad!
