Albedo
Albedo (albedo, meaning "whiteness") is the measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body (e.g. a planet like Earth).

Anne Frank
Annelies Marie Frank (12 June 1929 – February or March 1945)Research by The Anne Frank House in 2015 revealed that Frank may have died in February 1945 rather than in March, as Dutch authorities had long assumed.
