Niels Bohr and Max Planck. Historical portrait of the Danish physicist Niels Henrik David Bohr (1885-1962) with the German physicist Max Planck (1858-1947). Planck is at right. They were central figures in the development of quantum theory. Planck proposed in 1900 that radiation is emitted in discrete packets (quanta). Bohr's 1913 model of the hydrogen atom used quantized energy levels for electrons orbiting the nucleus. Bohr received the Nobel Prize for Physics in 1922, as Planck had in 1918. Photographed in 1930.

How many topics in physics are contained in a simple rainbow produced on the wall (and toilet) by sun shining through a plastic privacy screen?
Well...the light from the sun is composed of many different wavelengths...the distribution of which is dependent on the temperature of the star - which ours is centered on the the yellow. When the the light encounters an optically dense medium (glass or plastic in this case), the light is absorbed by the molecules and passed from molecule to molecule, the probability of which an absorption and emission occurs is described by Feynman's QED. The principle of least action (from D'Alembert and Lagrangian mechanics) finds the maximum probability amplitude, and hence the interaction that occurs, or the direction the light is refracted. The path of light through the medium is dependent on the wavelength and frequency of the light. One can back up to PAM Dirac's relativistic quantum mechanics, ingeniously melded Schrodinger's wave equation and/or Heisenberg's Matrix mechanics with Einstein's relativity, which determined that the only certainty in the universe is the speed of light. Everything else including Newton's fixed stars and time...TIME itself are mutable to make the speed of light constant in every situation. Dirac faced with the actual energy of a particle being the square root of the rest mass and its motion, devised a Hamiltonian that required matricies, later interpreted by Pauli as spin states of particles. Schoedinger and Heisenberg following Bohr's amazing leap of quantized orbits to describe Plancks description of light as quanta....actually they were named by Einstein to describe the photoelectric effect....but Planck needed the quantized description of light to explain the ultraviolet disaster of Rayleigh. Planck was working for the electric company to maximize the light output of municipal utilities at the least cost.... TBC

This is a block printed portrait of Danish physicist Niels Bohr (1885-1962). One of his most famous contributions to quantum mechanics was the Bohr-Rutherford model of the atom. Bohr is shown in front of the Bohr model of the Hydrogen atom (all the concentric circles are actually at the appropriate spacing, proportional to the n squared, which probably reflects on my sanity in some way). Bohr proposed that the orbits of electrons were somewhat like planetary orbits (though circular, and at specific quantized distances). To explain how orbitting charged electrons didn't lose energy and annihilate spectacularly with the so-called "spiral death" (physicists are big on melodrama, I'm telling you), he stipulated that perhaps they simply weren't allowed anywhere but the specific orbits. They could lower their energy state if excited by falling to a lower orbit, giving off a specific photon of a specific colour related to the difference between energy levels. This also explained how the spectra of gases had distinct, thin, spectral lines. I've illustrated this with the Balmer series - because it is composed of lines which are visible to the eye (H-alpha is red and caused by a jump from the 3rd to 2nd orbit; H-beta is cyan and caused by a jump from the 4th to 2nd orbit; H-gamma is indigo and caused by a jump from the 5th to 2nd orbit; and H-delta is violet and caused by a jump from the 6th to 2nd orbit). I've shown both the quantum jumps (squigelly arrows - squigelly lines are tradition for photons) and by the line spectrum below Bohr.

"This number signifies the initiate. 13 is an integral part of the creation pattern and is also known as 12+1. It is a Fibonacci number and also a prime. 13 is a symbol of transformation, and can represent a re-birth into a higher state of consciousness beyond the Earth plane. The lunar cycle also has 13 phases."
"Number Eleven is a master number and means birth or enlightenment. Others turn to 11 characters for teaching and inspiration and are usually uplifted by the experience. 11 is the divine base unit which begins at 1. God uses base 11, man uses base 10, erroneously believing in a theoretical concept called "zero"."

Have you ever considered that your clothes run long distances when cycling in your washing machine( WM)? Considering a mean WM of 45 cm of internal diameter, a normal program of 1h30min, and a maximum speed of 800rpm (which lasts only for a small frction of the entire program), then you can come with a total run path of 25 to 30 km!!! Where the 60% of the this path has been run during the centrifuge. With WMs that reach speeds of 1200-1400rpm the clothes can run over 35km!

♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!
ay, yo sé que duele parar aquí, pero vea quien es la #6
Esto se pone cada vez más y más complicado. Este señor sí que me hace sonreír. Feynmansito divino, es para mí, mi físico favorito!
Es indiscutible la importancia de Feynman para la física del siglo XX. Además, lo que más me gusta además de su pilera, es que todo lo emociona a tal nivel, que a uno le dan ganas de ser físico y trabajar en lo mismo que él, y ver el mundo como él lo ve.
Si usted ha tenido problemas entendiendo conceptos básicos de la física, pues véalo a él explicarlos y sienta que el mundo es demasiado cool, y demasiado TIN!
Fun to imagine 1 2 3 4 5 6 7 8 9 10 11
Desde pequeño curioso y estudioso, hacía preguntas que hacían repensar las cosas a todo aquel a quien se las preguntaba, una de las anécdotas que más me gustan es cuando en clase de biología en la Universidad, aprendiendo la anatomía de los felinos, Feynmancito pregunta al profesor: ¿Tiene un mapa del gato? Este tipo de preguntas, dejaba a la gente confundida
Su trabajo fue crucial, gracias a sus avances en electrodinámica cuántica, (que le valió el premio nobel de física en 1965), desarrolló la formulación integral de camino de la mecánica cuántica en la que se estudian todas las posibilidades de transición de un estado a otro, y el camino final es la suma de todas las posibilidades.
Tiene muchos descubrimientos y avances mas, que no explicaré aquí, porque no soy física y no los entiendo. Así que si quieren conocerlos, hay una cosa llamada wikipedia, que sirve su propósito.
Lo que sí voy a mencionar, es que desarrolló los diagramas de Feynman, que son un estilo de cuadernos para calcular y entender las interacciones de las partículas en el espacio y en el tiempo. Gracias a estos diagramas se le facilitó trabajar en conceptos como la reversabilidad del tiempo. HUH??!!! Yo quiero que alguien me explique esto! Porque si es lo que parece ser, pues me pido ese super poder!
Con estos diagramas, se ha logrado definir y avanzar en la teoría de cuerdas, (¿Recuerdan a nuestro querido Brian Greene?), y la teoría M.
Feynmansito cogió un pequeño número de partículas interactuando en el espacio-tiempo e intentó modelizar toda la física a partir de esas partículas, dando nacimiento a su teoría del partón, que fue derrotada por la teoría de quarks. Lo chévere sobre los científicos, es que pueden trabajar toda una vida en una teoría, y cuando alguna tra les demuestra que está mal, no les da miedo tirarla a la basura y abrazar la nueva. Así, Feynmancito abrazó la teoría de los quarks, y les explicó a sus estudiantes cuando se descubrió el quinto quark que su descubrimiento de hecho implicaba la existencia de un sexto quark, el cual fué descubierto una década después de que Feynmancito estuvo d.e.d.
Durante su trabajo en Caltech, dió su cátedra de física y de ahí salió su libro de "Conferencias de física de Feynman" y por ésto es que se le considera uno de los más grandes maestros de la enseñanza de la física EVER! aaayy lo amo!
¿No me creen? Párenle bolas a cómo explica todo! Uno se enamora de él, imposible no! Sus estudiantes se emocionaban en las teorías que él explicaba, volviéndose una competencia poder desarrollar las ecuaciones a toda costa. Lo amo! ♥!
Lo más TiN de Feynmancito, era su personalidad. Trabajando en Los Alamos, en la bomba atómica, se aburría inmensamente, por lo que se las ingeniaba para divertirse. Dejaba noticas en las cajas fuertes del laboratorio, para demostrarles que no eran tan seguras como se pensaban, salía a los bares a bailar, cantar, tocar bongos, y levantar chicas. Era un womanizer de primera! : ) debeno!
En uno de sus libros: "Surely you're joking Mr. Feynman" habla de una de sus experiencias. ¿lo quiere leer,? para picarle el interés, le digo que devela el secreto para conquistar chicas. (debo agradecer a winki ese link, como debería agradecerle muchas cosas en este proceso de 42 días, como por ejemplo que él me presentó a Gilbert y que muchas curiosidades y links, me los ha mandado el. tenks dude.)
Su visión sobre la religión y la fe, como siempre, perfectamente articulada! aquí
Aaaayy, no es divino? Ahí lo tienen, y sí, yo hice el video y la animación, y ese es él hablando de cauchos y partículas, en su muy neoyorkino acento. Love him.
yes... y como aún tenemos tin dudes, vea quien es el #4
