\nMax Planck, one of the fathers of quantum theory, recipient of the Nobel Prize in Physics (1918) and one of the most respected scientists of the 20th Century had to take on an early age what may seem to some a difficult decision: to devote himself to physics or music.[1]<\/sup><\/a><\/p>\n

Chroniclers tell us that the young Planck was highly gifted for music: he played piano, organ and cello and composed songs and operas. But he decided instead to pursuit a career in physics. Working on the problem of the black body radiation (i.e., the lack of agreement between the prediction of classical physics and the experimental wavelength distribution of the energy emitted by a black body as a function of temperature) he arrived to a conclusion that later became one of the fundamental cornerstones of the new physics of the 20th Century: electromagnetic radiation can only be emitted in quantized amounts, i.e., it cannot take whatever value but has to be a multiple of h\u03bd, where h is a universal constant (now called the Planck’s constant) and \u03bd is the frequency of the radiation. Few years after Planck’s finding, Albert Einstein gave the idea a new dimension when he explained the photoelectric effect considering that light is made of photons, i.e., discrete particles with an energy equal to h\u03bd (that is, quanta of light). Both scientists became close friends and played frequently music together at Planck’s home.[2]<\/sup><\/a><\/p>\n

\nMax Planck, uno de los padres de la teor\u00eda cu\u00e1ntica, ganador del Premio Nobel de F\u00edsica (1918) y uno de los cient\u00edficos m\u00e1s respetados del siglo XX tuvo que tomar en su juventud una decisi\u00f3n que a algunos les parecer\u00e1 dif\u00edcil: dedicarse a la m\u00fasica o a la f\u00edsica.[1]<\/sup><\/a><\/p>\n

Los cronistas cuentan que el joven Planck ten\u00eda un gran talento para la m\u00fasica: tocaba el piano, el \u00f3rgano y el chelo y compon\u00eda canciones y \u00f3peras. Decidi\u00f3, sin embargo, dedicarse a la f\u00edsica. Trabajando en el problema de la radiaci\u00f3n del cuerpo negro (el desacuerdo entre las predicciones de la f\u00edsica cl\u00e1sica y el espectro experimental de energ\u00eda emitida por un cuerpo negro en funci\u00f3n de la temperatura) lleg\u00f3 a una conclusi\u00f3n que m\u00e1s tarde se convirti\u00f3 en una de las piedras angulares de la nueva f\u00edsica del siglo XX: la radiaci\u00f3n electromagn\u00e9tica s\u00f3lo puede ser emitida en cantidades cuantizadas, es decir, su energ\u00eda no puede tomar cualquier valor, sino que ha de ser un m\u00faltiplo de h\u03bd, donde h es una constante universal (llamada ahora constante de Planck) y \u03bd es la frecuencia de la radiaci\u00f3n. Pocos a\u00f1os despu\u00e9s del hallazgo de Planck, Albert Einstein dio una nueva dimensi\u00f3n a esta idea, al explicar el efecto fotoel\u00e9ctrico considerando que la luz est\u00e1 hecha de fotones, es decir, part\u00edculas discretas con una energ\u00eda igual a h\u03bd (es decir, cuantos de luz). Ambos cient\u00edficos se hicieron grandes amigos y tocaban con frecuencia en casa de Planck.[2]<\/sup><\/a><\/p>\n
