Candela Candela The candela ( or ; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly
Félix Candela many of his peers, Candela didn’t show intellectual or aesthetic efforts in school. He didn’t even like pure mathematics. When Candela was a student in Madrid, the schools taught the theory of elasticity where Candela assisted the professors and even tutored other students. His studies ended very quickly when the Spanish civil war began in 1936. When Candela returned to Spain to fight, he sided with the republic and fought against Franco.
