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 ...
Annus mirabilis (pl. anni mirabiles) is a Latin phrase that means "marvelous year", "wonderful year", or "miraculous year". This term has been used to refer to several years during which events of major importance are remembered, notably Isaac Newton's discoveries in 1665–1666 at the age of 23 and Albert Einstein's papers published in 1905 at the age of 26.

In 1905, sometimes described as his annus mirabilis (miracle year), he published four groundbreaking papers. [10] In them, he outlined a theory of the photoelectric effect, explained Brownian motion, introduced his special theory of relativity, and demonstrated that if the special theory is correct, mass and energy are equivalent to each other.
Before his "miracle year" (1905), when Einstein was a patent clerk in Bern, the group of friends met to debate books in the fields of physics and philosophy. The group's origin lay in Einstein's need to offer private lessons in mathematics and physics in order to make a living (in 1901, before he took up his post at the patent office in Bern).
Within months, Einstein's description of Brownian motion was experimentally verified by Henry Siedentopf. [8]: 103–106 In 1905, Einstein developed his special theory of relativity, which reconciled the Galilean relativity of motion with the observed constancy of the speed of light (a paradox of 19th-century physics). [14]
It is one of the four groundbreaking papers Einstein published in 1905, in Annalen der Physik, in his miracle year. In 1827, botanist Robert Brown used a microscope to look at dust grains floating in water. He found that the floating grains were moving about erratically; a phenomenon that became known as "Brownian motion". This was thought to ...
