Web10 May 2024 · Ruby was invented by Yukihiro “Matz” Matsumoto, a Japanese computer programmer, in the mid-1990s. Matsumoto was an expert on multiple programming languages at the time, including Perl, Eiffel, Smalltalk, Lisp, and Ada. When creating Ruby, he tried to combine what he thought were the best elements of each of these languages. In 1917, Albert Einstein established the theoretical foundations for the laser and the maser in the paper "Zur Quantentheorie der Strahlung" ("On the Quantum Theory of Radiation") via a re-derivation of Max Planck's law of radiation, conceptually based upon probability coefficients (Einstein coefficients) for the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation. In 1928, Rudolf W. Ladenburg confirmed the existence of the phenome…
