Because Einstein published all four of these papers in a single year, 1905 is called his annus mirabilis (miraculous year). The first paper explained the photoelectric effect , which established the energy of the light quanta E = h f {\displaystyle E=hf} , and was the only specific discovery mentioned in the citation awarding Einstein the 1921 ...
The two-postulate basis for special relativity is the one historically used by Einstein, and it is sometimes the starting point today. As Einstein himself later acknowledged, the derivation of the Lorentz transformation tacitly makes use of some additional assumptions, including spatial homogeneity, isotropy, and memorylessness. [3]
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1] [1] [2]
Albert Einstein, physicist, 1879-1955, Graphic: Heikenwaelder Hugo,1999. Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists and mathematicians, see History of special relativity).
Einstein's 1905 derivation ascribed it to a restriction on the energy of radiation alone, but in this paper, he proposes the modern idea that the energies of both matter and radiation are quantized, which led to his work on quantum specific heats, such as reference #16. Schilpp 14; CP 2, 35: 1906
Modern analysis suggests that neither Einstein's original 1905 derivation of mass-energy equivalence nor the alternate derivation implied by his 1906 center-of-mass theorem are definitively correct. [21] [22] For instance, the center-of-mass thought experiment regards the cylinder as a completely rigid body.
In 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect. Einstein theorized that the energy in each quantum of light was equal to the frequency of light multiplied by a constant, later called the Planck constant .
The correctness of Einstein's 1905 derivation of E = mc 2 was criticized by German theoretical physicist Max Planck in 1907, who argued that it is only valid to first approximation. Another criticism was formulated by American physicist Herbert Ives in 1952 and the Israeli physicist Max Jammer in 1961, asserting that Einstein's derivation is ...
