What is the most cutting edge physics research right now?

There are three branches of theoretical physics: condensed matter, high energy, and astrophysics. Condensed matter has been very powerful recently, because graphene is harder than diamond, and the conductivity is also very good, so many people are researching.

Superconductors are also popular. High-energy physics isn't very popular right now, but particle colliders are being built in various countries, so it shouldn't be hard to find a job. Astrophysics is also relatively good, and it was finally confirmed in 08 that the universe is expanding at an accelerated pace, which is more powerful.

And more than 99% of the universe we don't know, so many people do research on the author's side.

Environmental engineering is a combination of chemistry, physics, and biology. Nanotechnology, closely related to materials science, is now the most cutting-edge chemistry as far as I know, is the study of the structure of matter, and the representative discipline is quantum chemistry, which.

To cite two ions, the argument for string thoery, supersymmetry, etc., the European Large Nuclear Collider is confirming or falsifying this theory.

There is also an experiment about neutrons being faster than the speed of light, which, if verified, would rewrite Einstein's theory of relativity, and other laboratories in the United States are repeating this experiment and will reveal the answer within a year.

There are new basic theories of physics (or new basic laws of physics), published on page 171 of the 12th issue of Science and Technology Innovation Herald in 2008!

Neutrons with a speed exceeding the speed of light.

Uh, Tesla.

Exploring the universe upstairs?

Now the energy crisis.

Isn't Tesla's Cosmic Linear Energy Receiver the hottest?

And geophysics**?

I don't quite understand either.

Anyway, the Tesla effect is very powerful.

Physics is the natural science that studies the most basic structure, the most universal interactions, the most general laws of motion, and the experimental means and thinking methods used in the material world.

In modern times, physics has become one of the most fundamental disciplines in the natural sciences. The laws of physics that have been verified by a large number of rigorous experiments are called laws of physics. However, like many other theories of the natural sciences, these laws cannot be proven, and their correctness can only be tested through repeated experiments.

The word "physics" first came from the Greek word for 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 in the late Ming and early Qing dynasties.

Scientist Fang Yizhi.

The encyclopedic work "Physics Tips".

In the field of physics, the basic components of the universe are studied: matter, energy, space, time and their interactions. A complete understanding of the system is achieved through the fundamental laws and laws that are being analyzed. Physics in classical times consisted of the study of natural philosophy, which was very similar to it, and it was not until the nineteenth century that physics was separated from philosophy and became an empirical science.

Learning method: Feynman, a famous physicist.

"Science is a method," he said. It teaches people:

how some things are understood, what things are known, to what extent are they understood, how doubts and uncertainties are treated, and what laws are obeyed by evidence; How to think about things, how to make judgments, how to distinguish between truth and falsehood and superficial phenomena? ”

Famous physicist Albert Einstein.

"Develop independent thinking.

and the general ability to make independent judgments, which should always come first, and professional knowledge should not be given priority. If a person has mastered the basic theories of his discipline and has learned to think and work independently, he will certainly find his own way, and he will certainly be better able to adapt to progress and change than the kind of person who mainly takes the acquisition of detailed knowledge as the content of his training. ”

Research interests: particle physics and nuclear physics, astrophysics, atomic and molecular photophysics, condensed matter physics, etc

Physics is a discipline that studies the most general laws of the motion of matter and the basic structure of matter. As a leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, from the universe to elementary particles, so it has become the research foundation of other natural science disciplines.

The theoretical structure of physics makes full use of mathematics as its working language, and experiments as the only criterion for testing the correctness of theories.

Physics field of study.

1. Condensed matter physics - the study of the macroscopic properties of matter, which contain a very large number of components and strong interactions between members. The most familiar condensed matter phases are solids and liquids, which are formed by bonds between atoms and electromagnetic forces.

2. Atomic, Molecular and Optical Physics – the study of matter-matter and light-matter interactions within the size of an atom or the structure of several atoms. These three areas are closely related. Because they use similar methods and scales related to energy.

3. High-energy particle physics - particle physics studies the basic components of matter and energy and the interactions between them; It can also be referred to as high-energy physics. Because many elementary superfluous particles do not exist in nature, they only appear when they collide with other particles in a particle accelerator.

4. Astrophysics - Astrophysics and astronomy are the theories and methods of physics used to study the structure and evolution of stars, the origin of the solar system, and related problems of the universe.

The nature of physics.

Physics is a regular summary of people's knowledge of the transformation of matter in inanimate nature. There should be two kinds of such movements and transformations. The first is the extension of sensory vision in the early days, and the second is the foundation of the indirectly understanding of the internal composition of matter through the invention and creation of scientific instruments for observation and measurement in modern times.

Hello dear, the following are some of the fields that are currently considered to be the frontier of physics: 1. Quantum computing: Using the properties of quantum mechanics to research and develop quantum computers for computing, which are still in the research stage.

2. Quantum communication: The properties of quantum mechanics are used to ensure the security of communication, so that eavesdroppers cannot steal the communication content. 3. Plasma physics:

The study of ionization phenomena in plasmas, electromagnetic fields, and plasma-solid surface interactions includes nuclear fusion ballast energy and high-power lasers. 4. Particle physics: the study of the basic composition and interaction of matter, the study of high-energy particle accelerators and particle detectors, for the study of the origin of the universe and the detection of unknown particles.

5. Many-body quantum physics: the quantum mechanical theory of the interaction between multiple quantum objects, which can be applied to the design of new materials and the development of new electronic devices. 6. Gravitational wave astronomy:

Laser interferometers are used to detect gravitational waves and detect major events in the universe, such as black hole mergers and neutron star collisions. 7. Solar physics: study the composition, activity, magnetic field and influence of the sun on the earth, understand the physical mechanism of solar storms and solar flares, and the relationship with earth meteorology and satellite communications.

8. Physics of new materials: the study of the physical properties and applications of new materials, such as Eryu rock stove dimensional materials, quantum dots, etc., can be applied to the development of new electronic devices and energy materials.

Theoretical physics is an important discipline to explore the truth of the universe, and the two pillars of modern physics are relativity and quantum mechanics, but the two are not unified, and there are even contradictions.

Theoretical physicists are always on the lookout for more advanced theories that will help physics unify relativity and quantum mechanics, and even find a "grand unification theory" for the universe in general. Cutting-edge theoretical physicists have been extending other more advanced theories based on the theory of relativity and quantum mechanics, including the "string theory" based on quantum mechanics.

The main goal of theoretical physicists is to use theory to unify physical phenomena in the universe. Newton once proposed Newtonian classical mechanics, which can explain almost all physical phenomena that occur on the earth, but with the development of physics, Newton's classical mechanics began to show limitations.

Physicists always make small errors when they use Newton's classical mechanics to perform various calculations of the universe, but no one can explain why these errors exist, and it was not until Einstein proposed the theory of relativity that scientists learned that space can bend and the speed of time can change.

The theory of relativity, as the backbone of modern physics, still has the dominant position, but with the discovery of the microscopic world, the theory of relativity began to show limitations.

In order to adapt the theory of relativity to the microscopic world, physicists extended quantum mechanics through the theory of relativity, and the two theories played a role in different occasions to explain the physical laws of the universe.

But what theoretical physicists want is not a complex world of multiple physical theories, but a "grand unified theory" that theoretically explains all fundamental forces.

Cutting-edge theoretical physicists have been looking for a unified theory that can explain the entire universe, and string theory is considered to be the most likely advanced theory to become a unified theory.

String theory further breaks down microscopic particles into strings, which can produce vibrations in different directions, which in turn form different particles in our world. But for a single string to form a very complex kind of particle, it needs to vibrate in at least 10 dimensions, so string theory also implies that the universe is 10 dimensions.

String theory is a very advanced theory, and almost all conclusions cannot be verified by modern science, so many theoretical physicists call string theory opportunistic.

Theoretically, string theory does unify the theory of relativity and quantum mechanics, thereforeString theory is also the closest physical theory to the grand unification theory. In addition to string theory, the theory of relativity and quantum mechanics have also been evolving, and the theory of relativity, which can use gravity perfectly explained by space, has become a bottleneck in quantum mechanical theory, and scientists have been experimenting with hadron impacts in the hope of discovering particles that can produce gravity.

What theoretical physicists are constantly looking for is a unified theory that requires innovative thinking about physics, which may never be found, or may unify physics in the near future.

Theoretical physics is an important discipline for mankind to explore the secrets of the early universe, and cutting-edge physicists use their professional knowledge to help physics unify relativity and quantum mechanics.

In theoretical physics, cutting-edge physicists generally study the quantum realm, molecular structure, quantum mechanics, and the unified theory of relativity.

1. Introduction to the frontier development of physics in the fields of low-dimensional condensed matter physics, optics and technology, nonlinear physics, fluid microflow, nuclear physics, etc.

2. Low-dimensional physics mainly involves thin film physics, quantum Hall effect, graphene and carbon nanotubes, conductive luminescent plastics, etc., solid, liquid, gaseous, plasma, bose, Einstein leakage condensed matter, Fermi condensed matter, and boson system.

3. For bosons, the number of particles that can be accommodated in a quantum state is not limited, and the particles will occupy the lowest state of swimming delay energy as much as possible at absolute zero, and all of them will be at the lowest energy level of zero energy at absolute zero degrees of leakage, forming a system composed of Bose Einstein condensate fermions.
