Albert Einstein publishes four articles that will revolutionize physics. Three of them are published in volume 17 of Annalen der Physik. In the first, he hypothesizes that light is composed of quantized particles (later called photons). In the second, he explains Brownian motion with the thermal noise of atoms. In the third, completely theoretical and without bibliographical citations, he publishes Special Relativity. All this while he is employed at the Swiss Patent Office and his wife is giving birth to his second child (their first daughter, born in 1901 out of wedlock, dies at just two years old).
