Luminous gems are common theme in comparative mythology. Ball cross-culturally analyzed stories about luminous stones and pearls and found about one hundred variants in ancient, medieval, and modern sources. The wide-ranging locations of the tales comprise all Asia (except Siberia), all Europe (except Norway and Russia), Borneo, New Guinea, the ...
Luminous energy is related to radiant energy by the expression = / ¯ (). Here λ {\displaystyle \lambda } is the wavelength of light, and y ¯ ( λ ) {\displaystyle {\overline {y}}(\lambda )} is the luminous efficiency function , which represents the eye's sensitivity to different wavelengths of light.
Luminous mind (Skt: prabhāsvara-citta or ābhāsvara-citta, Pali: pabhassara citta; Tib: འོད་གསལ་གྱི་སེམས་ ’od gsal gyi sems; Ch: 光明心 guangmingxin; Jpn: 清浄心 syōzyōshin) is a Buddhist term that appears only rarely in the Pali Canon, but is common in the Mahayana sūtras [1] [2] and central to ...
Note that even the most luminous stars are much less luminous than the more luminous persistent extragalactic objects, such as quasars. For example, 3C 273 has an average apparent magnitude of 12.8 (when observing with a telescope), but an absolute magnitude of −26.7.
Luminous intensity is the perceived power per unit solid angle. If a lamp has a 1 lumen bulb and the optics of the lamp are set up to focus the light evenly into a 1 steradian beam, then the beam would have a luminous intensity of 1 candela.
"When form is the object of observation or drshyam, then the eye is the observer or drk; when the eye is the object of observation, then the mind is the observer; when the pulsations of the mind are the objects of observation, then Sakshi or the Witnessing-Self is the real observer; and it is always the observer, and, being self-luminous, can ...
Feroz-ul-Lughat Urdu Jamia (Urdu: فیروز الغات اردو جامع) is an Urdu-to-Urdu dictionary published by Ferozsons (Private) Limited. It was originally compiled by Maulvi Ferozeuddin in 1897. The dictionary contains about 100,000 ancient and popular words, compounds, derivatives, idioms, proverbs, and modern scientific, literary ...
In photometry, luminous flux or luminous power [citation needed] is the measure of the perceived power of light. It differs from radiant flux , the measure of the total power of electromagnetic radiation (including infrared , ultraviolet , and visible light), in that luminous flux is adjusted to reflect the varying sensitivity of the human eye ...
