Graphical view of Planck's law for a black body (an ideal absorber and emitter). Planck's law states that any body that has a temperature above absolute zero emits electromagnetic radiation at all wavelengths. We can use Planck's law to predict the temperature of a remote body without actually being there, but seeing how much radiance is emitted by it on the spectrum we're scanning on. That's friggin awesome!
Heat radiation of smallest objects: Theories beyond Planck's law describe this emission very accurately.
October 1900 – Max Planck, in his house at Grunewald, on the outskirts of Berlin, discovers the law of black-body radiation (Planck's law).
Classical physics (Rayleigh–Jeans law, black line) failed to explain black body radiation – the so-called ultraviolet catastrophe. The quantum description (Planck's law, colored lines) is said to be modern physics.

Max Karl Ernst Ludwig Planck, ForMemRS (April 1858 – October was a German theoretical physicist who originated quantum theory, which won him the Nobel Prize in Physics in
Sun and Earth's emission spectrum: Sun's is 3000/6000 = 0.5 micrometer wavelength (using Wien's Law); Earth's is 3000/288 = 10.41 micrometer wavelength; Sun and Earth are approximately black body radiators (snow is in the infrared); energy emission rate is given by: Stefan-Boltzman law (total emission), Wien's Law (peak emission wavelength), Planck's law (wavelength dependent emission)
quantum physics -----and spirituality - Quantum physics :--- means that makes up the universe as well as everything in it, both the seen and unseen, is all energy or light . Quantum Physics --is a detailed study of how EVERYTHING in.
Predictions of the amount of thermal radiation of different frequencies emitted by a body. Correct values predicted by Planck's law (green) contrasted against the classical values (Rayleigh–Jeans law, red and Wien approximation, blue).
What is the Bohr Model of the Atom?: The Bohr Model of the atom is a planetary model in which the electrons orbit around the atomic nucleus.
