The International Year of Physics commemorates which of Einstein s theoretical contributions

100 years ago, the 26-year-old genius physicist Albert Einstein completed six epoch-making articles in one go, including three great achievements in modern physics: the theory of molecular motion, the special theory of relativity and the optical quantum hypothesis, which have influenced the development of physics over the past century. This year is known as the "Year of Miracles".

On the occasion of the 100th anniversary of this "miracle year", the global physics community unanimously called for 2005 to be the "World Year of Physics". The initiative was first proposed by the European Physical Society and unanimously adopted by the International Union of Pure and Applied Physics. In June 2004, the 58th session of the United Nations General Assembly adopted a resolution establishing 2005 as the International Year of Physics.

In 2005, the global physics community will organize a series of events to commemorate the 100th anniversary of the birth of the theory of relativity and the 50th anniversary of the death of Albert Einstein.

In June 2004, the United Nations General Assembly adopted a resolution calling 2005 the International Year of Physics.

1905 was a special year in the history of science, when the unknown Albert Einstein published five articles** that completely changed the traditional physics and laid the foundation for many technologies that benefited future generations. One hundred years later, the United Nations adopted a General Assembly resolution designating 2005 as the International Year of Physics to commemorate this "year of miracles". The year also coincides with the 50th anniversary of Albert Einstein's death.

In 1905, Albert Einstein published five papers**, covering three areas: the photoelectric effect, Brownian motion, and special relativity. Although these articles have different topics, they are all foundational works in their respective fields. The British journal Nature said in a commemorative article published on January 20.

Answer]: cc [Analysis] Einstein's theory of relativity is a major revolution in physical thought, and he reveals that time and space are not absolutely unchanging. Einstein's theory of relativity is a basic theory about space-time and gravity, mainly founded by Einstein, and is divided into special relativity (special relativity) and general relativity (general relativity).

The basic assumption of relativity is the principle of relativity, that is, the laws of physics have nothing to do with the choice of frame of reference. The answer discussed in the special theory of relativity is the physical laws between inertial frames of reference for uniform linear motion, which are generalized to frames of reference with acceleration (non-inertial frames) and widely used in gravitational fields under the assumption of the equivalence principle. The theory of relativity subverts the common-sense concept of the universe and nature, and puts forward new concepts such as "the relativity of time and space", "four-dimensional space-time", and "curved space".

The special theory of relativity was proposed in 1905, and the general theory of relativity was proposed in l915.

Answer]: C Einstein's Shenqiao theory of relativity reveals that time and space are not absolutely invariant Zen codes, and can widely explain matter in different states of migration, thus solving a series of problems that cannot be explained by Newtonian mechanics based on ultra-low speed motion.

Answer]: c Einstein's theory of relative elimination reveals that time and space are not absolutely unchanging, and can widely explain the downward movement of matter in different states of motion, thus solving a series of problems that cannot be explained by Newtonian mechanics based on ultra-low motion. Therefore, the answer to this question is C.

d:a, Einstein's mass-energy equation e=mc2 tells us that the energy possessed by an object is proportional to its mass, so a is correct

b, e= mc2 where m is the loss of mass, e is the release of nuclear energy, so b is correct c, if the mass is lost in the nuclear reaction, energy must be released, so when a proton and a neutron combine to form a deuterium nucleus, the energy is released, indicating that there is a mass loss in this process so c is correct

d, e=mc2 in e is the energy possessed by the object so d is false clear about the meaning of the individual quantities of e=mc2 and e= mc2

The biggest contribution is as you say: the theory of relativity – the "mass-energy relation".

In addition to this, there is also a photoelectric effect.

In 1905, Albert Einstein proposed the hypothesis of photon deficiency and successfully explained the photoelectric effect, so he was awarded the Nobel Prize in Physics in 1921.

The greatest contribution is as you say: the theory of relativity—".

Quality and reputation grasp the relationship.

And in addition to that, there are.

Photoelectric effect. In 1905, Einstein proposed the photon hypothesis, which successfully explained the imitation of the electric effect of the light preparation virtual shed, so it was obtained in 1921.

Nobel Prize in Physics.
