The Zohar (Hebrew: זֹהַר , Zōhar, lit."Splendor" or "Radiance" [a]) is a foundational work of Kabbalistic literature. [1] It is a group of books including commentary on the mystical aspects of the Torah and scriptural interpretations as well as material on mysticism, mythical cosmogony, and mystical psychology.
Brightness temperature or radiance temperature is a measure of the intensity of electromagnetic energy coming from a source. [1] In particular, it is the temperature at which a black body would have to be in order to duplicate the observed intensity of a grey body object at a frequency ν {\displaystyle \nu } . [ 2 ]
For an ideal absorber/emitter or black body, the Stefan–Boltzmann law states that the total energy radiated per unit surface area per unit time (also known as the radiant exitance) is directly proportional to the fourth power of the black body's temperature, T: =.
Radiance is used to characterize diffuse emission and reflection of electromagnetic radiation, and to quantify emission of neutrinos and other particles. The SI unit of radiance is the watt per steradian per square metre (W·sr −1 ·m −2). It is a directional quantity: the radiance of a surface depends on the direction from which it is ...
It is often simply called a book club, a term that may cause confusion with a book sales club. Other terms include reading group , book group , and book discussion group . Book discussion clubs may meet in private homes, libraries , bookstores , online forums, pubs, and cafés, or restaurants, sometimes over meals or drinks.
The novel is set in South Africa, home to five distinct populations: Bantu (native Black tribes), Coloured (the result of generations of racial mixture between persons of European descent and the indigenous occupants of South Africa along with slaves brought in from Angola, Indonesia, India, Madagascar and the east Coast of Africa), British, Afrikaner, and Indian, Chinese, and other foreign ...
The number of photons/sec directed into any wedge is proportional to the area of the wedge. Figure 2: Observed intensity (photons/(s·m 2 ·sr)) for a normal and off-normal observer; dA 0 is the area of the observing aperture and d Ω is the solid angle subtended by the aperture from the viewpoint of the emitting area element.
