Las funciones de Bessel describen la parte radial de . En matemáticas, las funciones de Bessel, primero definidas por el matemático Daniel Bernoulli y más tarde generalizadas por Friedrich Bessel, son soluciones canónicas y ( x) de la ecuación diferencial de Bessel: ( 1) donde es un número real o complejo.
27 de jun. de 2018 · Bessel, Friedrich Wilhelm (1784–1846) German astronomer and mathematician. Bessel devised a system for analysing and reducing astronomical observations, made the first accepted measurements of the distance of a star (61 Cygni), and accurately predicted that Sirius and Procyon are binary stars.
The work of the German astronomer and mathematician Friedrich Wilhelm Bessel (1784 –1846) provides a good illustration. Among his many other accomplishments, Bessel developed techniques to measure the positions of stars with far greater accuracy than previously possible.
"Friedrich Wilhelm Bessel" published on by null. (1784–1846)Germanmathematician and astronomer. After compiling a fundamental catalogue of 3000 stars (1818), he began an extensive programme of measuring star positions and proper motions.
Friedrich Wilhelm Bessel (Minden, 22 de julho de 1784 — Königsberg, 17 de março de 1846) foi um matemático, físico e astrônomo alemão. Foi o primeiro astrônomo a determinar valores confiáveis da distância do Sol para outra estrela, através do método da paralaxe .
