   Lumosity is an online program consisting of games claiming to improve memory, attention, flexibility, speed of processing, and problem solving. [2] History.

3. Luminosity - Wikipedia

   en.wikipedia.org/wiki/Luminosity

   Luminosity is an absolute measure of radiated electromagnetic energy (light) per unit time, and is synonymous with the radiant power emitted by a light-emitting object. [1][2] In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical objects. [3][4] In SI units ...

4. Luminous intensity - Wikipedia

   en.wikipedia.org/wiki/Luminous_intensity

   Luminous intensity. In photometry, luminous intensity is a measure of the wavelength -weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.

5. Stellar classification - Wikipedia

   en.wikipedia.org/wiki/Stellar_classification

   Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.

6. Mass–luminosity relation - Wikipedia

   en.wikipedia.org/wiki/Mass–luminosity_relation

   Mass–luminosity relation. In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star's mass and its luminosity, first noted by Jakob Karl Ernst Halm. [1] The relationship is represented by the equation: where L⊙ and M⊙ are the luminosity and mass of the Sun and 1 < a < 6. [2]

8. Luminous efficiency function - Wikipedia

   en.wikipedia.org/wiki/Luminous_efficiency_function

   The CIE photopic luminous efficiency function y(λ) or V(λ) is a standard function established by the Commission Internationale de l'Éclairage (CIE) and standardized in collaboration with the ISO, [1] and may be used to convert radiant energy into luminous (i.e., visible) energy. It also forms the central color matching function in the CIE ...
